description: High-contrast imaging studies of debris disks have revealed a significant diversity in their morphologies, including large-scale asymmetries. Theories involving stellar flybys, an external source of gravitational disturbance, have offered a plausible explanation for the origin of these morphological variations. Our study is an experiment to gain empirical evidence that has been lacking from such theories. We explore this paradigm by using astrometric and radial velocity measurements from the Gaia DR2 and ground-based observations to trace the trajectories of 625 stars in the Sco-Cen OB Association from 5 Myr in the past to 2 Myr in the future. We identified 119 stars that had at least one past flyby event occurring within one Hill radius, and 23 of these experienced flybys within 0.5 Hill radius. We found no evidence of a significant correlation between the presence of flyby events and infrared excess detections, although the sample is not uniformly sensitive to infrared excess emission. Ten stars that had past flyby events host resolved circumstellar disks that appear relatively symmetric in the existing data except for the circumbinary disk surrounding HD 106906. We determined the trajectory and relative velocity of each of these flyby events, and compared these to the geometry of the spatially-resolved disks. Future work is needed to measure the kinematics of lower mass stars and to improve sensitivity to circumstellar disks for the entire sample.

description: Rovibrational bands spectra of three $ν_{20}$, $ν_7$ and $ν_{19}$ bands of 1, 3, 5 -- trioxane (H$_2$CO)$_3$ were recorded in the 50--650 cm$^{-1}$ range using a long path absorption cell coupled to a high resolution Fourier transform spectrometer and synchrotron radiation at the AILES beamline of the SOLEIL synchrotron. More than 16000 lines were assigned with a dRMS better than $0.17\times10^{-3}$ cm$^{-1}$. Two different formalisms (tensorial and Watson) were used to derive accurate rotational and quartic parameters for the three bands and for the first time, a precise determination of Coriolis parameter and $q_+$ $l-$doubling constant for both $ν_{20}$ and $ν_{19}$ perpendicular bands was obtained. Last, each set of spectroscopic parameters is compared and discussed between both formalisms.

Paint a Vulgar Picture. On the Relationship Between Images and Projects in Our Work

description: The essay is a reflection on the production of images in the work of our practice, Dogma. Since the onset of our work, we were interested in architectural images as both explanations of architecture and real abstractions, and in developing a representation method that was consistent with the content of our design work. Critical of the realist character of the computer renderings and of its ideological underpinnings, we started producing our first digital collages in an analogical way for our first large-scale proposals of the early 2000s. In this work, avoiding the formal complexity of early digital architecture, we used images to abstract architecture, namely to reduce architecture to simple formal compositions of built masses. These early images avoided the typical effects of early computer renderings by using simple found textures or by imagining interventions as simple cut-outs of a given context picture. The technique of using found images and cutting out things in them led us to rediscover the pictorial dimension of images and to use paintings and art photography as source materials for our own representation work. In this period, we were particularly fascinated by the early work of Thomas Ruff and Andreas Gursky, and in that of painters such as David Hockney, Peter Doig and Henri Rousseau. Since 2010, following a series of housing competitions, we started to become interested in domestic space and its potential for transformation. This interest unfolded in a long research by design trajectory, in which we have tried to further develop our representation technique in line with our design agenda. The images produced for this set of projects are based on a few common characteristics, such as the deployment of the central perspective as a tool to de-individuate the subject of our architecture, the avoidance of any stylistic or linguistic concerns, the deployment of simple and non-descriptive furniture, hinting to the possible uses of domestic space without imposing predetermined functions. Our essay articulates and reflects on the relationship between our design ideas and representation and our understanding of drawing as the place of mental creation and material expression.

description: Box–Cox power transformation is a commonly used methodology to transform the distribution of the data into a normal distribution. The methodology relies on a single transformation parameter. In this study, we focus on the estimation of this parameter. For this purpose, we employ seven popular goodness-of-fit tests for normality, namely Shapiro–Wilk, Anderson–Darling, Cramer-von Mises, Pearson Chi-square, Shapiro-Francia, Lilliefors and Jarque–Bera tests, together with a searching algorithm. The searching algorithm is based on finding the argument of the minimum or maximum depending on the test, i.e., maximum for the Shapiro–Wilk and Shapiro–Francia, minimum for the rest. The artificial covariate method of Dag et al. (2014) is also included for comparison purposes. Simulation studies are implemented to compare the performances of the methods. Results show that Shapiro–Wilk and the artificial covariate method are more effective than the others and Pearson Chi-square is the worst performing method. The methods are also applied to two real-life datasets. The R package AID is proposed for implementation of the aforementioned methods.

description: For the first time in the history of photography, digital photographers can now experiment with photographic effects and immediately review the results. This capability, which is crucial for experimentation, opens up a new world of imagery with slow shutter speeds that 'paint' light in a variety of ways. Yet some people believe that the effects of movement in slow-exposure photography are about the same and accidental. Nothing could be further from the truth. There is a quite sophisticated vocabulary, a physics of light and motion, that can be understood and once understood is not accidental. This eBook details the ways these different motions are recorded in photographs and the new artwork that is now possible -- work that has its roots in modern art.

This PowerPoint show also explains how the black and white microphotographs of snow crystals by W.A. "Snowflake" Bentley in 1885 were converted to colored images. Using a technique similar to staining, Rick Doble colored the original Bentley images (in the public domain) to bring out the structure of the crystals. Doble explains his process in this presentation along with a lavish display of his colored snowflakes. These colored photographs have been widely used in elementary schools and also at the college level. They have also been featured in libraries and in the national media. Documentation about these mentions are included at the end of this presentation. Permission is given to educators and non-profit organizations to use these images, as long as the artist is credited.

description: A lot of thought goes into what we sit on. From the design of the office chair to the cafe bench, kitchen stool, or couch where we watch television. For consumers, even more thought goes into what we sit on when we fly. Either domestic or international, we all have ourpreferences. Starting with which airline, then the location within the aeroplane—either up front or behind the wing. Finally, our preference for aisle or window, but never choosing a middle seat. Choice matters and can influence passengers to pay more than an economy fare. Design also plays a part and can affect a consumer's experience when flying. Good design can also play a role in linking innovation and the commercial success of products and services. Airplane seating is no exception.
Less thought goes into understanding the importance of design. Qantas Airlines Australia, however, recognized the importance of design and equally its protection and with the inception of the Skybed, it changed the perception of international business-class travel and what it means to fly. Design played a key role and created a consumer experience that was more functionally efficient and more aesthetically pleasing. The Qantas Skybed is an illustrative example of the unseen connections between industry, designer, consumer experience and design law.
In 2001, Qantas approached Marc Newson, a designer famous for his Lockheed Lounge and Embryo chair, to create a new business-class seat. The seat would need to recline and produce a flat bed. Qantas knew what drove customers to choose business class: comfort, privacy, and flexibility. The Newson seat would achieve all this, but also create a new sense of space for passengers either while working, relaxing, sleeping, or being entertained. Newson designed a retro-futuristic business-class seat with a sculpted carbon fibre back shell. Although not the first flatbed business-class seat—British Airways introduced the first in 1999—the Skybed was the longest at two meters fully reclined. The innovative design went on to win the Good Design Award from the Chicago Athenaeum Museum in 2003 and, a year later, an Australian Design Award. Following the successful launch and acclaim of the Skybed, Qantas asked Marc Newson back to redesign the entire cabin interior of Qantas’ new A380 fleet. To Qantas, the Skybed was the crown jewel of a $385 million modernization process.

description: Using high-throughput first-principles calculations to search for layered van der Waals materials with the largest piezoelectric stress coefficients, we discover NbOI2 to be the one among 2940 monolayers screened. The piezoelectric performance of NbOI2 is independent of thickness, and its electromechanical coupling factor of near unity is a hallmark of optimal interconversion between electrical and mechanical energy. Laser scanning vibrometer studies on bulk and few-layer NbOI2 crystals verify their huge piezoelectric responses, which exceed internal references such as In2Se3 and CuInP2S6. Furthermore, we provide insights into the atomic origins of anti-correlated piezoelectric and ferroelectric responses in NbOX2 (X = Cl, Br, I), based on bond covalency and structural distortions in these materials. Our discovery that NbOI2 has the largest piezoelectric stress coefficients among 2D materials calls for the development of NbOI2-based flexible nanoscale piezoelectric devices.

description: This is a cross-sectional review of biomarkers used in air pollution research from January 2009 through December 2012. After an initial keyword search in PubMed retrieving 426 articles, a comprehensive abstract review identified 54 articles of experimental design that used biomarkers of exposure or effect in human studies in the area of air pollution research during this specified time period. A thorough bibliographic search of the included articles retrieved an additional 65 articles meeting the inclusion criteria. This review presents these 119 studies and the 234 biomarkers employed in these air pollution research investigations. Data presented are 70 biomarkers of exposure with 54% relating to polycyclic aromatic hydrocarbons, 36% volatile organic carbons, and 10% classified as other. Of the 164 biomarkers of effect, 91 and 130 were used in investigating effects of short-term and chronic exposure, respectively. Results of biomarkers used in short-term exposure describe different lag times and pollutant components such as primary and secondary pollutants, and particle number associated with corresponding physiological mechanisms including airway inflammation, neuroinflammation, ocular, metabolic, early endothelial dysfunction, coagulation, atherosclerosis, autonomic nervous system, oxidative stress, and DNA damage. The review presents three different exposure scenarios of chronic, occupational, and extreme exposure scenarios (indoor cooking) with associated biomarker findings presented in three broad categories of (1) immune profile, (2) oxidative stress, and (3) DNA damage. This review offers a representation of the scope of data being explored by air pollution researchers through the use of biomarkers and has deliberately been restricted to this particular subject rather than an extensive or in-depth review. This article provides a contextualization of air pollution studies conducted with biomarkers in human subjects in given areas while also integrating this complex body of information to offer a useful review for investigators in this field of study.

description: In gauge-Higgs unification (GHU), gauge symmetry is dynamically broken by an Aharonov-Bohm (AB) phase, $θ_H$, in the fifth dimension. We analyze $SU(2)$ GHU with an $SU(2)$ doublet fermion in flat $M^4 \times (S^1/Z_2)$ spacetime and in the Randall-Sundrum (RS) warped space. With orbifold boundary conditions the $U(1)$ part of gauge symmetry remains unbroken at $θ_H = 0$ and $π$. The fermion multiplet has chiral zero modes at $θ_H = 0$, which become massive at $θ_H = π$. In other words chiral fermions are transformed to vectorlike fermions by the AB phase $θ_H$. Chiral anomaly at $θ_H = 0$ continuously varies as $θ_H$ and vanishes at $θ_H=π$. We demonstrate this intriguing phenomenon in the RS space in which there occurs no level crossing in the mass spectrum and everything varies smoothly. The flat spacetime limit is singular as the AdS curvature of the RS space diminishes, and reproduces the result in the flat spacetime. Anomalies appear for various combinations of Kaluza-Klein excitation modes of gauge fields as well. Although the magnitude of anomalies depends on $θ_{H}$ and the warp factor of the RS space, it does not depend on the bulk mass parameter of the fermion field controlling its mass and wave function at general $θ_H$.

Spontaneous Coronary Artery Dissection – Advanced Phenotyping and Risk Stratification in Key Subpopulations
Creators: name: Wood, Alice
Publisher: name: University of Leicester
Year: 2024

description: BackgroundSpontaneous coronary artery dissection (SCAD) is an uncommon cause of myocardial infarction predominantly affecting women. It is caused by the development of a false lumen in the arterial wall leading to compression of the true lumen and myocardial infarction.MethodsThe thesis is comprised of three studies. Study one is a phenotyping study of women with a history of two or more SCAD events compared with matched healthy controls. Participants underwent clinical assessment and detailed phenotyping with brachial artery flow mediated dilatation, cardiopulmonary exercise testing, quantitative adenosine and psychological stress MRI perfusion and ambulatory ECG monitoring. Study two is a phenotyping study of men with SCAD compared with matched healthy controls, who underwent the same tests as the women. Study three is an observational study of a larger group of men from the SCAD registry; these men were compared to a previously studied female group in terms of demographic data, clinical history, risk factors and recurrent events.ResultsCardiopulmonary exercise testing demonstrated both male and female SCAD patients to have a significantly greater increase in blood pressure per unit workload than healthy controls (P=0.002 for male, 0.02 for female). Female recurrent SCAD participants had lower myocardial perfusion reserve with psychological stress than healthy controls (P=0.022).Men were found to have recurrent SCAD sooner than women, at 2.66 versus 4.43 years after their first SCAD.Female SCAD patients showed greater flow mediated dilatation than healthy controls (P = 0.0145) whilst male SCAD patients had greater nitrate mediated dilatation (P=0.041).Many of the other test results did not differ between SCAD patients and healthy controls.ConclusionsSCAD survivors did not differ significantly from healthy controls in terms of measures of autonomic dysfunction or myocardial perfusion at rest and with adenosine stress.Female SCAD patients had greater flow mediated dilatation than controls, whereas male SCAD patients had greater nitrate mediated dilatation.Both female recurrent and male SCAD survivors showed an enhanced blood pressure response to exercise, and female recurrent patients showed a reduced level of perfusion with psychological stress.Male SCAD patients experience recurrence earlier than female SCAD participants.

description: Embedding molecular symmetries into machine-learning models is key for efficient learning of chemico-physical scalar properties, but little evidence on how to extend the same strategy to tensorial quantities exists. Here we formulate a scalable equivariant machine-learning model based on local atomic environment descriptors. We apply it to a series of molecules and show that accurate predictions can be achieved for a comprehensive list of dielectric and magnetic tensorial properties of different ranks. These results show that equivariant models are a promising platform to extend the scope of machine learning in materials modelling.

Two models of the dependence of the refractive index of the defect layer on the concentration of the pathogen in water were considered. The optimal parameters for the photonic crystal in our device and the optimal thickness of the defect layer were determined. It was also demonstrated that in the presence of absorption in the investigated structure it is much more advantageous to work in the reflection mode compared to the transmission mode. Finally, the wavelength dependence of the defect mode on the SARS-CoV-2 concentration was obtained and the sensitivity of the sensor was determined.

description: The US and China were embroiled in the trade battle war in the year 2018 their power struggle has also played out the technology sectors with Chinese telecoms giant Huawei becoming the central part of their dispute. The company has consistently denied the allegations and many in China argue the US is trying to curb the technology ambition. Huawei has repeatedly denied claims that it will help the Chinese government spy or disrupt other countries’ government telecom systems. Huawei resolutely incorporates requirements of the EU’s General Data Protection Regulation (GDPR) in all of its business processes. They are investing heavily to upgrade the existing networks and build a new network. The case study presents marketing in Malta as an innovation from a blockchain island to an artificial intelligence nation.

description: Background: Internet-based interventions can make self-management and recovery-oriented information and tools more accessible for people experiencing severe mental illness, including psychosis. The aim of this scoping review was to identify and describe emerging joint uses of these Internet-based interventions by service users experiencing psychosis and mental health workers. It also investigated how using these Internet-based interventions influenced interactions between service users and workers and whether recovery-oriented working practices were elicited. Methods: A scoping review method was used. Iterative review stages included identifying the review question, a comprehensive search including searching six electronic databases to locate relevant studies, selecting studies, charting the data, and collating and reporting the results. Rigour of the scoping review was enhanced by using an appraisal tool to evaluate the quality of included studies, and by using a published template for systematic description of interventions. Results: Fifteen papers about eleven Internet-based interventions that focused on self-management and/or recovery were identified. Interventions were web-based, mobile-device based, or both. The eleven interventions were used by service users either with their usual mental health workers, or with mental health workers employed in a research project. Emerging evidence suggested that jointly using an Internet-based intervention could support a positive sense of working together. However, mismatched expectations and poor integration of Internet-based interventions into service systems could also negatively influence interactions, leading to mistrust. The interventions demonstrated potential to elicit recognised recovery-oriented practices, specifically understanding service users' values and supporting their goal striving. Conclusions: The use of Internet-based interventions focused on self-management and recovery in mental health services by service users and workers jointly demonstrates potential to support working together and recovery-oriented practice. Given that the quality of relationships is critical in recovery-oriented practice, greater focus on human support in Internet-based interventions is needed in future research and practice.
Quark and gluon entanglement in the proton on the light cone at intermediate $x$

description: In QCD with $N_c$ colors the anti-symmetric valence quark color space singlet state $\sim ε_{i_1\cdots i_{N_c}} |i_1,\cdots, i_{N_c}\rangle$ of the proton corresponds to the reduced density matrix $ρ_{ij}=(1/N_c) δ_{ij}$ for a single color degree of freedom. Its degenerate spectrum of eigenvalues, $λ_i=1/N_c$, the purity $\mathrm{tr}~ρ^2 = 1/N_c$, and the von~Neumann entropy $S_\mathrm{vN}=\log(N_c)$ all indicate maximal entanglement of color. On the other hand, for $N_c\to\infty$ the spatial wave function of the proton factorizes into valence quark wave functions determined by a mean field (E. Witten, Nucl. Phys. B 160 (1979) p. 57) where there is no entanglement of spatial degrees of freedom. A model calculation at $N_c=3$ using a simple three quark model light-front wave function by Brodsky and Schlumpf, predicts percent level entanglement of spatial degrees of freedom. Using light-cone perturbation theory we also derive the density matrix associated with the four parton $|qqqg\rangle$ Fock state. Tracing out the quarks, we construct the reduced density matrix for the degrees of freedom of the gluon, which encodes its entanglement with the sources. Our expressions provide the dependence of the density matrix on the soft cutoff $x$ for the gluon light-cone momentum, and on the collinear and ultraviolet regulators. Numerical results obtained in a simple approximation indicate stronger entanglement for the gluon (with $x_g < \langle x_q\rangle$) than for quarks in the three quark Fock state.

description: The measurement of the apsidal motion in close eccentric massive binary systems provides essential information to probe the internal structure of the stars that compose the system. Following the determination of the fundamental stellar and binary parameters, we make use of the tidally induced apsidal motion to infer constraints on the internal structure of the stars composing the binary system HD152219. The extensive set of spectroscopic, photometric, and radial velocity observations allows us to constrain the fundamental parameters of the stars together with the rate of apsidal motion of the system. Stellar structure and evolution models are further built with the Clés code testing different prescriptions for the internal mixing occurring inside the stars. The effect of stellar rotation axis misalignment with respect to the normal to the orbital plane on our interpretation of the apsidal motion in terms of internal structure constants is investigated. Made of an O9.5 III primary star (M1 = 18.64+/-0.47M${_\odot}$, R1 = 9.40+0.14-0.15R${_\odot}$, Teff,1 = 30900+/-1000 K) and a B1-2 V-III secondary star (M2 = 7.70+/-0.12M${_\odot}$, R2 = 3.69+/-0.06R${_\odot}$, Teff,2 = 21697+/-1000 K), the binary system HD152219 displays apsidal motion at a rate (1.198+/-0.300)°yr-1. The weighted-average mean of the internal structure constant of the binary system is inferred: k2 = 0.00173+/-0.00052. For the Clés models to reproduce the k2-value of the primary star, a significant enhanced mixing is required, notably through the turbulent mixing, but at the cost that other stellar parameters cannot be reproduced simultaneously. The difficulty to reproduce the k2-value simultaneously with the stellar parameters as well as the incompatibility between the age estimates of the primary and secondary stars are indications that some physics of the stellar interior are still not completely understood.

description: The ongoing Changi East Reclamation Project in Singapore consists of land reclamation and ground improvement of the foreshore for the future expansion of Changi International Airport. The deformation behaviour of marine clay under reclamation fills and surcharge was modelled by the finite element method (FEM) with Plaxis numerical modelling software. The analyses included modelling the consolidation behaviour of marine clay under reclamation fills with and without prefabricated vertical drains. Marine clay with vertical drains was modelled by both the axisymmetric unit cell and full-scale analysis methods. Marine clay that was not treated with prefabricated vertical drains was modelled by means of full-scale analysis. The numerical analysis was carried out at two case study locations: the pilot test site and the in situ test site. The test sites comprise vertical drain treated and untreated sub-areas that were reclaimed and preloaded under the same conditions. The result of the FEM analysis was compared with that obtained by means of observational methods. The vertical drain performance was verified for the in situ test site by using the value of Ch obtained from back-analysis by the Asaoka method and by FEM with Plaxis.

description: The dissipative mechanism in weakly collisional plasma is a topic that pervades decades of studies without a consensus solution. We compare several energy dissipation estimates based on energy transfer processes in plasma turbulence and provide justification for the pressure-strain interaction as a direct estimate of the energy dissipation rate. The global and scale-by-scale energy balances are examined in 2.5D and 3D kinetic simulations. We show that the global internal energy increase and the temperature enhancement of each species are directly tracked by the pressure-strain interaction. The incompressive part of the pressure-strain interaction dominates over its compressive part in all simulations considered. The scale-by-scale energy balance is quantified by scale filtered Vlasov-Maxwell equations, a kinetic plasma approach, and the lag dependent von Kármán-Howarth equation, an approach based on fluid models. We find that the energy balance is exactly satisfied across all scales, but the lack of a well-defined inertial range influences the distribution of the energy budget among different terms in the inertial range. Therefore, the widespread use of the Yaglom relation to estimating dissipation rate is questionable in some cases, especially when the scale separation in the system is not clearly defined. In contrast, the pressure-strain interaction balances exactly the dissipation rate at kinetic scales regardless of the scale separation.

description: The ongoing Changi East Reclamation Project in Singapore consists of land reclamation and ground improvement works of the foreshore for the future expansion of the Changi International airport and associated facilities. Reclamation works in the project involve the hydraulic placement of sand-fill over the seabed, which is underlain by thick, highly compressible Singapore marine clay. Ground improvement works in the project comprise the installation of vertical drains and the subsequent placement of surcharge to accelerate the consolidation of the underlying marine clay. A pilot test site was carried out in the project, comprising three sub-areas that were installed with vertical drains at various spacings, plus a fourth untreated sub-area. The four sub-areas were surcharged simultaneously and preloaded for a duration of 32 months. A comprehensive field instrumentation programme was implemented in the pilot test site, comprising settlement plates, deep settlement gauges, piezometers and water standpipes. The degree of improvement attained by the foundation soil at each sub-area was determined and assessed during the process of consolidation and 32 months after surcharge placement using the observational method. This paper describes the applications and comparisons between the Asaoka method, the hyperbolic method and piezometers in monitoring the improvement of marine clay under reclamation fills.

description: The aim of this work is to characterize HCN and CH$_3$OH emission from recent comets. We used the Onsala 20-m telescope to search for millimetre transitions of HCN towards a sample of 11 recent and mostly bright comets in the period December 2016 to November 2019. Also CH$_3$OH was searched for in two comets. The HCN sample includes the interstellar comet 2I/Borisov. For the short-period comet 46P/Wirtanen we could monitor the variation of HCN emission over a time span of about one month. We performed radiative transfer modelling for the observed molecular emission by also including time-dependent effects due to the outgassing of molecules. HCN was detected in 6 comets. Two of these are short-period comets and 4 of them are long-period. Six methanol transitions were detected in 46P/Wirtanen, enabling us to determine the gas kinetic temperature. From the observations, we determined the molecular production rates using time-dependent radiative transfer modelling. For 5 comets, we could determine that the HCN mixing ratios lie near 0.1% using contemporary water production rates, $Q_\mathrm{H_2O}$, taken from other studies. This HCN mixing ratio was also found typical in our monitoring observations of 46P/Wirtanen but here we notice deviations, on a daily time scale, up to 0.2% which could indicate short-time changes in the outgassing activity. From our radiative transfer modelling of cometary comae, we found that time-dependent effects on the HCN level populations are of the order 5-15% when $Q_\mathrm{H_2O}$ is around $2\times 10^{28}\,\mathrm{mol\, s^{-1}}$. The effects may be relatively stronger for comets with lower $Q_\mathrm{H_2O}$. The exact details of the time-dependent effects depend on the amount of neutral and electron collisions, radiative pumping, and molecular parameters such as the spontaneous rate coefficient.

description: We present an explicit formula for Lorentz boosts and rotations that commute with BMS supertranslations in asymptotically flat spacetimes. Key to the construction is the use of infrared regularizations and of a unitary transformation that makes observables commute with the soft degrees of freedom. We explicitly verify that our charges satisfy the Lorentz algebra and we check that they are consistent with expectations by evaluating them on the supertranslated Minkowski space and on the boosted Kerr black hole.

description: The recently proposed bianisotropic acoustic metagratings offer promising opportunities for passive acoustic wavefront manipulation, which is of particular interest in flat acoustic lenses and ultrasound imaging at ultra-high frequency ultrasound. Despite this fact, acoustic metagratings have never been scaled to MHz frequencies that are common in ultrasound imaging. One of the greatest challenges is the production of complex structures of microscopic size. Owing to two-photon polymerization, a novel fabrication technique from the view of acoustic metamaterials, it is now possible to precisely manufacture sub-wavelength structures in this frequency range. However, shrinking in size poses another challenge; the increasing thermoviscous effects lead to considerable losses, which must be taken into account in the design. In this work we propose three microacoustic metagrating designs refracting a normally incident wave towards -35$^{\circ}$ at 2 MHz. In order to develop metaatoms insensitive to thermoviscous effects we use shape optimization techniques incorporating the linearized Navier-Stokes equations discretized with finite element method. We report for the first time microscopic acoustic metamaterials manufactured using two-photon polymerization and, subsequently, experimentally verify their effectively using a capacitive micromachined ultrasonic transducer as source and an optical microphone as a detector in a range from 1.8 MHz to 2.2 MHz. We demonstrate not just that a microacoustic metagrating can effectively redirect the normally incident wave despite the thermoviscous losses, but also that it being only 0.29$λ$ thick can allocate 90% of the transmitted energy in the $-$1st diffraction order.

description: The spirohydantoin-containing cucurbitane-type triterpenoid, kaguacidine A (1), was isolated and purified from 95% ethanol extract of vines of Momordica charantia L. (Cucurbitaceae). Its unprecedented chemical structure, a spirohydantoin substituent at C-23 of cucurbitane, was elucidated by extensive spectroscopic analyses, including HRESIMS, IR, optical rotation, 1 D- and 2 D-NMR spectra. The possible biosynthetic pathway is deduced and may be attributed to the metabolic activity of microbial symbionts in M. charantia L. Compound 1 was evaluated for anti-inflammatory activity against LPS-induced NO production in RAW 264.7 cells and anti-proliferative activity against four cancer cell lines, including HEp-2, MCF-7, Hep-G2, and WiDr. Compound 1 showed moderate anti-inflammatory activity with an IC50 value of 18.5 ± 0.4 μg/mL and weak anti-proliferative activity against MCF-7, HEp-2, Hep-G2, and WiDr with IC50 values of >40, 33.8 ± 0.6, 31.0 ± 0.7, and 27.0 ± 0.7 μM, respectively.

description: Unimodular gravity (UG) is an interesting theory that may explain why the cosmological constant is extremely small, in contrast to general relativity (GR). The theory has only the transverse diffeomorphism invariance and this causes lots of debate as to the equivalence of UG to GR in the covariant quantization. We study the covariant BRST quantization of UG by gauge fixing only the transverse diffeomorphism and show that the remaining physical degrees of freedom are two, the same number as GR. This is achieved by using antisymmetric tensor ghost fields which automatically satisfy the transverse condition without nonlocal projection operator. The theory exhibits the ghosts for ghosts phenomenon, which requires further gauge fixing and introduction of more ghosts. We identify the BRST quartet structure among the various fields and single out the remaining physical degrees of freedom.
