description: A natural extension of the Pasterski-Shao-Strominger (PSS) prescription is described, enabling the map of Minkowski space amplitudes with massive spinning external legs to the celestial sphere to be performed. An integral representation for the conformal primary wave function (CPW) of massive spinning bosons on the celestial sphere is derived explicitly for spin-one and -two. By analogy with the spin-zero case, the spinning bulk-to-boundary propagator on Euclidean AdS is employed to extend the massive CPW integral representation to arbitrary integer spin, and to describe the appropriate inverse transform of massive spinning CPWs back to the plane wave basis in Minkowski space. Subsequently, a massive spin-$s$ momentum operator representation on the celestial sphere is determined, and used in conjunction with known Lorentz generators to derive Poincaré symmetry constraints on generic massive spinning two-, three- and four-point celestial amplitude structures. Finally, as a consistency check, three-point Minkowski space amplitudes of two massless scalars and a spin-one or -two massive boson are explicitly mapped to the celestial sphere, and the resulting three-point function coefficients are confirmed to be in exact agreement with the results obtained from Poincaré symmetry constraints.

description: In this paper we use a path-integral approach to represent the Lyapunov exponents of both deterministic and stochastic dynamical systems. In both cases the relevant correlation functions are obtained from a (one-dimensional) supersymmetric field theory whose Hamiltonian, in the deterministic case, coincides with the Lie-derivative of the associated Hamiltonian flow. The generalized Lyapunov exponents turn out to be related to the partition functions of the respective super-Hamiltonian restricted to the spaces of fixed form-degree.

description: Σκοπός της μεταπτυχιακής αυτής εργασίας ήταν η παραγωγή μιας υβριδικής πρωτεΐνης αποτελούμενης από το αμινο-τελικό τμήμα του LBR που εκτείνεται στο πυρηνόπλασμα και της TM7SF2 που εντοπίζεται στο ενδοπλασματικό δίκτυο και να διαπιστωθεί η υποκυτταρική εντόπιση της υβριδικής πρωτεΐνης. Η πρωτεΐνη TM7SF2 παρουσιάζει εκτεταμένη ομολογία αλληλουχίας με το διαμεμβρανικό τμήμα του LBR. Παρατηρήθηκε ότι τόσο το διαμεμβρανικό τμήμα του LBR όσο και η πρωτεΐνη TM7SF2 μπορούν να λειτουργήσουν ως ένζυμα που καταλύουν την αναγωγή του C14-ακόρεστου δεσμού της λανοστερόλης, με πολλές ασθένειες να συνδέονται με μεταλλάξεις που παρεμποδίζουν την ενζυμική αυτή λειτουργία. Δεδομένου ότι ο LBR εντοπίζεται στην εσωτερική πυρηνική μεμβράνη και η TM7SF2 στο ενδοπλασματικό δίκτυο, κατασκευάσαμε μία πρωτεΐνη σύντηξης LBRTM7SF2 στην οποία αντικαταστήσαμε το διαμεμβρανικό τμήμα του LBR με την πρωτεΐνη TM7SF2. Για τον σκοπό αυτό χρησιμοποιήσαμε ένα cDNA που κωδικοποιεί την αμινο-τελική περιοχή του LBR και ένα cDNA που κωδικοποιεί την TM7SF2 στα οποία ενσωματώσαμε τα κατάλληλα άκρα ώστε να ενωθούν μεταξύ τους και στην συνέχεια να ενσωματωθούν στον πλασμιδιακό φορέα pEGFP-N1. Στην συνέχεια, επιμολύναμε κύτταρα HeLa με τους ανασυνδυασμένους πλασμιδιακούς φορείς, με απώτερο σκοπό να μελετήσουμε την υποκυτταρική εντόπιση της νέας πρωτεΐνης. Μέσω ανοσοφθορισμού που ακολούθησε, διαπιστώσαμε ότι η πρωτεΐνη σύντηξης εντοπίζεται τελικά περιμετρικά του πυρηνικού φακέλου
description: The aim of this dissertation was to produce a hybrid protein consisting of the amino-terminal portion of LBR, extending into the nucleoplasm, and TM7SF2, located in the endoplasmic reticulum, and to determine the subcellular localization of the hybrid protein. The TM7SF2 protein exhibits extensive sequence homology to the transmembrane portion of LBR. It has been observed that both the transmembrane portion of LBR and the TM7SF2 protein can function as enzymes that catalyze the reduction of the C14-unsaturated bond of lanosterol, with many diseases being associated with mutations that inhibit this enzymatic function. Since LBR is located in the inner nuclear membrane and TM7SF2 in the endoplasmic reticulum, we constructed an LBRTM7SF2 fusion protein in which we replaced the transmembrane portion of LBR with the TM7SF2 protein. For this purpose we used a cDNA encoding the amino-terminal region of LBR and a cDNA encoding TM7SF2 in which we inserted the appropriate ends to join them and then integrate into the plasmid vector pEGFP-N1. We transfected HeLa cells with the recombinant plasmid vectors in order to study the subcellular localization of the new protein. Through immunofluorescence that followed, we found that the fusion protein was eventually located around the perimeter of the nuclear envelope

description: High resolution echelle spectra of PW And (HD~1405) have been taken during eight observing runs from 1999 to 2002. The detailed analysis of the spectra allow us to determine its spectral type (K2V), mean heliocentric radial velocity (V_hel = -11.15 km/s) rotational velocity (vsin{i} = 22.6 km/s), and equivalent width of the lithium line 6707.8 AA (EW(LiI) = 273 mAA). The kinematic (Galactic Velocity (U, V, W)) confirms its membership of the Local Association moving group, in agreement with the age (30 to 80 Myrs) inferred from the color magnitude diagram and the lithium equivalent width. Photospheric activity (presence of cool spots that disturb the profiles of the photospheric lines) has been detected as changes in the the bisectors of the cross correlation function (CCF) resulting of cross-correlate the spectra of PW And with the spectrum of a non active star of similar spectral type. These variations of the CCF bisectors are related to the variations in the measured radial velocities and are modulated with a period similar to the photometric period of the star. At the same time, chromospheric activity has been analyzed, using the spectral subtraction technique and simultaneous spectroscopic observations of the H_alpha, H_beta, NaI D_1 and D_2$, HeI D_3, MgI b triplet, CaII H&K, and CaII infrared triplet lines. A flare was observed during the last observing run of 2001, showing an enhancement in the observed chromospheric lines. A less powerful flare was observed on 2002 August 23. The variations of the chromospheric activity indicators seem to be related to the photospheric activity. A correlation between radial velocity, changes in the CCF bisectors and equivalent width of different chromospheric lines is observed with a different behaviour between epochs 1999, 2001 and 2002.

description: Automatic melanoma segmentation in dermoscopic images is essential in computer-aided diagnosis of skin cancer. Existing methods may suffer from the hole and shrink problems with limited segmentation performance. To tackle these issues, we propose a novel complementary network with adaptive receptive filed learning. Instead of regarding the segmentation task independently, we introduce a foreground network to detect melanoma lesions and a background network to mask non-melanoma regions. Moreover, we propose adaptive atrous convolution (AAC) and knowledge aggregation module (KAM) to fill holes and alleviate the shrink problems. AAC explicitly controls the receptive field at multiple scales and KAM convolves shallow feature maps by dilated convolutions with adaptive receptive fields, which are adjusted according to deep feature maps. In addition, a novel mutual loss is proposed to utilize the dependency between the foreground and background networks, thereby enabling the reciprocally influence within these two networks. Consequently, this mutual training strategy enables the semi-supervised learning and improve the boundary-sensitivity. Training with Skin Imaging Collaboration (ISIC) 2018 skin lesion segmentation dataset, our method achieves a dice co-efficient of 86.4% and shows better performance compared with state-of-the-art melanoma segmentation methods.

description: Gamma Ray Bursts (GRBs) are expected to leave behind GRB remnants, similar to how ``standard'' supernovae (SN) leave behind SN remnants. The identification of these remnants in our own and in nearby galaxies would allow a much closer look at GRB birth sites, and possibly lead to the discovery of the compact object left behind. It would also provide independent constraints on GRB rates and energetics. We have initiated an observational program to search for GRB remnants in nearby galaxies. The identification is based on specific line ratios, such as OIII/$H_β$ and HeII/$H_β$, which are expected to be unusually high in case of GRB remnants according to the theoretical predictions of Perna et al. (2000). The observing strategies and preliminary studies from a test run at 2.34 m VBT as well as archival data from planetary nebulae surveys of spiral galaxies are discussed.

description: Determination of defect ionization energy in low-dimensional semiconductors has been a long-standing unsolved problem in first-principles defect calculations because the commonly used methods based on jellium model introduce an unphysical charge density uniformly distributed in the material and vacuum regions, causing the well-known divergence issue of charged defect formation energies. Here in this work, by considering the physical process of defect ionization, we propose a charge correction method based on jellium model to replace the unphysical jellium background charge density with the band edge charge density to deal with charged defects. We demonstrate that, our method is physically meaningful, quantitatively accurate and technically simple to determine the defect ionization energies, thus solving the long-standing problem in defect calculations. Our proposed method can be applied to any dimensional semiconductors.

description: Objective: Intensive care unit (ICU) cost estimates are critical to achieving healthcare system efficiency and sustainability. We aimed to review the published literature describing ICU costs in Australia. Design: A systematic review was conducted to identify studies that estimated the cost of ICU care in Australia. Studies conducted in specific patient cohorts or on specific treatments were excluded. Data sources: Relevant studies were sourced from a previously published review (1970–2016), a systematic search of MEDLINE and EMBASE (2016–5 May 2023), and reference checking. Review methods: A tool was developed to assess study quality and risk of bias (maximum score 57/57). Total and component costs were tabulated and indexed to 2022 Australian Dollars. Costing methodologies and study quality assessments were summarised. Results: Six costing studies met the inclusion criteria. Study quality scores were low (15/41 to 35/47). Most studies were conducted only in tertiary metropolitan public ICUs; sample sizes ranged from 100 to 10,204 patients. One study used data collected within the past 10 years. Mean daily ICU costs ranged from $966 to $5381 and mean total ICU admission costs $4888 to $14,606. Three studies used a top-down costing approach, deriving cost estimates from budget reports. The other three studies used both bottom-up and top-down costing approaches. Bottom-up approaches collected individual patient resource use. Conclusions: Available ICU cost estimates are largely outdated and lack granular data. Future research is needed to estimate ICU costs that better reflect current practice and patient complexity and to determine the best methods for generating these estimates.

Η ιστιδίνη αντιδρά με την ο-φθαλαλδεΰδη (ΟΡΑ) σε ελαφρώς αλκαλικό περιβάλλον και απουσία πυρηνόφιλων αντιδραστηρίων, για να σχηματίσει ένα φθορίζον παράγωγο (360/440 nm).Η γραμμικότητα βρέθηκε στην περιοχή των 500 - 25000 nmol L-1 με όριο ανίχνευσης 160 nmol L-1. Η απουσία της επίδρασης του υποστρώματος (<5%) επέτρεψε την επεξεργασία πραγματικών δειγμάτων μετά από ελάχιστη προεπεξεργασία. Η ενδογενής ιστιδίνη προσδιορίστηκε στον ανθρώπινο ορό στην περιοχή 78 - 119 μmol L-1 και στα τυχαία ανθρώπινα ούρα στην περιοχή 266 - 2034 μmol L-1. Το ποσοστό ανάκτησης ήταν ικανοποιητικό σε όλες τις περιπτώσεις, κυμαινόμενο μεταξύ 89 και 114%.
description: Τhe present study reports the development, optimization, validation and application of a fully automated method for the determination of low levels of histidine in urine and blood samples, using High Performance Liquid Chromatography.Histidine was separated from the matrix by cation exchange chromatography and detected selectively using on-line post column derivatization and fluorimetric detection. Unique reaction of Histidine with o-phthalaldehyde in the absence of nucleophilic compounds offered specific detection(360/440 nm). in the complex biological substrate. Linearity was obeyed in the range of 500 – 25000 nmol L-1 with a limit of detection of 160 nmol L-1. The absence of matrix effect (< 5%) enabled the processing of real samples after minimal pretreatment. Endogenous Histidine has been determined in human serum in the range of 78 – 119 μmol L-1 and random human urine in the range of 266 – 2034 μmol L-1. The percent recoveries were satisfactory in all cases, ranging between 89 and 114 %.

description: We propose a relationship between thermodynamic phase transitions and ground-state quantum phase transitions in systems with variable Hamiltonian parameters. It is based on a link between zeros of the canonical partition function at complex temperatures and exceptional points of a quantum Hamiltonian in the complex-extended parameter space. This approach is applied in the interacting boson model, where it is shown to properly distinguish the first- and second-order phase transitions.

description: The dynamics of vortices in type II superconductors exhibit a variety of patterns whose origin is poorly understood. This is partly due to the nonlinearity of the vortex mobility which gives rise to singular behavior in the vortex densities. Such singular behavior complicates the application of standard linear stability analysis. In this paper, as a first step towards dealing with these dynamical phenomena, we analyze the dynamical stability of a front between vortices and antivortices. In particular we focus on the question of whether an instability of the vortex front can occur in the absence of a coupling to the temperature. Borrowing ideas developed for singular bacterial growth fronts, we perform an explicit linear stability analysis which shows that, for sufficiently large front velocities and in the absence of coupling to the temperature, such vortex fronts are stable even in the presence of in-plane anisotropy. This result differs from previous conclusions drawn on the basis of approximate calculations for stationary fronts. As our method extends to more complicated models, which could include coupling to the temperature or to other fields, it provides the basis for a more systematic stability analysis of nonlinear vortex front dynamics.

Owing to the difficulty in conducting high-cadence observations of the Galactic plane over its vast area, which are necessary for the detection of microlensing events, their global properties were hitherto unknown. Here, we present results of the first comprehensive search for microlensing events in the Galactic plane. We searched an area of almost 3000 square degrees along the Galactic plane (|b|<7, 0

description: In the present work, planar polycyclic conjugated systems have been studied in terms of their magnetic properties both with the standard methodology applied on hydrocarbons, as well as with the use of the Pseudo-π hydrogen model in order to conclude whether this method provides us with computational cheap and scientifically reliable description, interpretation and prediction of aromaticity / anti-aromaticity in these systems. The optimizations of the various geometries wereperformedwith DFTcomputational methods. Initially, NICS XY-Scan calculations were performed on all molecules in both hydrocarbons and the corresponding hydrogen models and we proceeded to compare the results using diagrams. The induced magnetic field of the total magnetic response, as well as the magnetic response of the HOMO molecular orbital and HOMO-1 molecular orbital where necessary, was visualized. The study we performed confirmed that the Pseudo-π model is a reliable tool for the study of polycyclic conjugated systems with anti-aromatic rings. Finally, we compared the isomers to each other and investigated whether the substitution and the geometry affect the aromaticity or in this case the anti-aromaticity of the molecules

description: In the wake of President Carter's decision to suspend the sale of agricultural goods to the Soviet Union, the Administration has sought to offset potential declines in farm prices. As a result, agricultural issues took on an even more important role when the 96th Congress resumed in 1980. Congress had completed work on several important agricultural issues in the first session of the 96th Congress and laid the groundwork for 1980 decisions in other areas-including grain target prices and gasohol production. The overnight transformation of these issues to very high priority made early 1980 a lively time for agriculture on Capitol Hill. Of course all plans and schedules in Congress will be subject to revision as Congress responds to events developing abroad.

description: Background and aim: Increasing the diversity of future healthcare professionals is essential to support inclusive patient care. However, course inherent requirements (IRs) may act as (un)intentional and potentially harmful gatekeepers to diverse students entering entry-to-practice courses. A decade beyond the establishment of formal IRs, it is timely to reconsider if and how IRs might be impacting diversity and inclusion. Methods: This study analysed IRs published by the 37 Australian universities offering nursing and midwifery entry-to-practice courses. Findings: IRs were not uniform across all institutions. Most universities placed the responsibility to meet IRs solely upon the student, without sufficient information about possible reasonable adjustments. When institutional support was offered, the level of and means of accessing support were often unclear, again putting the onus to navigate support structures on the student. Discussion and conclusions: Whilst it is helpful for prospective students to understand the types of tasks they will be required to undertake as part of learning within the course and upon graduation, many IRs may be better positioned as expected learning. With increasing student diversity, alternate models requiring all students to demonstrate readiness for clinical placement immediately before placement may be helpful. Rather than presenting a static list of requirements, diverse students and practitioners may be better supported through the concept of ‘fitness to practice’ where more flexible and in-the-moment evaluations can be made.

description: We have studied the cubic to tetragonal phase transition in epitaxial SrTiO$_3$ films under various biaxial strain conditions using synchrotron X-ray diffraction. Measuring the superlattice peak associated with TiO$_6$ octahedra rotation in the low temperature tetragonal phase indicates the presence of a phase transition whose critical temperature is a strong function of strain, with T$_C$ as much as 50K above the corresponding bulk temperature. Surprisingly, the lattice constants evolve smoothly through the transition with no indication of a phase change. This signals an important change in the nature of the phase transition due to the epitaxy strain and substrate clamping effect. The internal degrees of freedom (TiO$_6$ rotations) have become uncoupled from the overall lattice shape.

description: The astounding growth in the number of grocery items-most of which are touted as novel by their manufacturers-is a main feature of contemporary grocery merchandising. But opinions vary greatly on whether this food product proliferation benefits consumers. Estimates of its extent tend to vary widely because they are based on different concepts of proliferation. Moreover, most positions on the topic appear to use unstated economic rationales with little or no empirical evidence.

description: This paper revisits the analysis of the implications of China's economic growth on her trading partners presented in Arndt et al. (1997) using a dynamic, applied general equilibrium model that features international capital mobility. We find that accounting for the impact of China's growth on international capital markets reverses some of the findings in the paper by Arndt et al. In particular, net creditor regions lose while net debtor regions benefit from an economic slowdown in China due to the resulting decline in the cost of capital. Our analysis also reveals the importance of capital accumulation effects which interact with non-capital factor productivity and tax distortions in determining regional welfare.

description: The Solar Wind Electrons Alphas and Protons experiment on the Parker Solar Probe (PSP) mission measures the three-dimensional electron velocity distribution function. We derive the parameters of the core, halo, and strahl populations utilizing a combination of fitting to model distributions and numerical integration for $\sim 100,000$ electron distributions measured near the Sun on the first two PSP orbits, which reached heliocentric distances as small as $\sim 0.17$ AU. As expected, the electron core density and temperature increase with decreasing heliocentric distance, while the ratio of electron thermal pressure to magnetic pressure ($β_e$) decreases. These quantities have radial scaling consistent with previous observations farther from the Sun, with superposed variations associated with different solar wind streams. The density in the strahl also increases; however, the density of the halo plateaus and even decreases at perihelion, leading to a large strahl/halo ratio near the Sun. As at greater heliocentric distances, the core has a sunward drift relative to the proton frame, which balances the current carried by the strahl, satisfying the zero-current condition necessary to maintain quasi-neutrality. Many characteristics of the electron distributions near perihelion have trends with solar wind flow speed, $β_e$, and/or collisional age. Near the Sun, some trends not clearly seen at 1 AU become apparent, including anti-correlations between wind speed and both electron temperature and heat flux. These trends help us understand the mechanisms that shape the solar wind electron distributions at an early stage of their evolution.

Is your chapter hoping to engage community partners to inspire, share skills and wisdom, and provide opportunities to your members? If so, this session is for you. The goal of this session is to share a framework for interacting with potential and existing community partners (i.e., government, businesses, non-profits, etc.) and fostering meaningful relations that benefit both parties. Our chapter will discuss what these partnerships may look like. Then, we will use our newly-formed relationship with NASA as an example, and walk through how we fostered this relationship and what both parties gained from it. We will discuss what materials a chapter should consider to prepare and discuss how tasks from company partners can be delegated using committees to divide responsibilities. Participants will learn strategies for communicating and identifying these needs of their chapter; while also tips for setting clear and reasonable requests with partners.

How Consumption and Repulsion Set Planetary Gap Depths and the Final Masses of Gas Giants

description: Planets open gaps in discs. Gap opening is typically modeled by considering the planetary Lindblad torque which repels disc gas away from the planet's orbit. But gaps also clear because the planet consumes local material. We present a simple, easy-to-use, analytic framework for calculating how gaps deplete and how the disc's structure as a whole changes by the combined action of Lindblad repulsion and planetary consumption. The final mass to which a gap-embedded gas giant grows is derived in tandem. The analytics are tested against 1D numerical experiments and calibrated using published multi-dimensional simulations. In viscous alpha discs, the planet, while clearing a gap, initially accretes practically all of the gas that tries to diffuse past, rapidly achieving super-Jupiter if not brown dwarf status. By contrast, in inviscid discs---that may still accrete onto their central stars by, say, magnetized winds---planets open deep, repulsion-dominated gaps. Then only a small fraction of the disc accretion flow is diverted onto the planet, which grows to a fraction of a Jupiter mass. Transitional disc cavities might be cleared by families of such low-mass objects opening inviscid, repulsion-dominated, overlapping gaps which allow most of the outer disc gas to flow unimpeded onto host stars.

description: We have studied the effect of irreversibility induced by repeated thermal cycles on the electric transport and magnetization of polycrystalline samples of La0.5Ca0.5MnO3 and La0.325Pr0.3Ca0.375MnO3. An increase of the resistivity and a decrease of the magnetization at different temperature ranges after cycling is obtained in the temperature range between 300 K and 30 K. Both compounds are known to exhibit intrinsic submicrometric coexistence of phases and undergo a sequence of phase transitions related to structural changes. Changes induced by thermal cycling can be partially inhibited by applying magnetic field and hydrostatic pressure. Our results suggest that the growth and coexistence of phases with different structures gives rise to microstructural tracks and strain accommodation, producing the observed irreversibility. Irrespective of the actual ground state of each compound, the effect of thermal cycling is towards an increase of the amount of the insulating phase in both compounds.

Publisher: name: Unknown
Year: 2000
Subjects: Consumer/Household Economics

description: The GTAP final demand system has some known defects: the computation of the equivalent variation is not exact; with non-standard demand parameters, the equivalent variation may be grossly in error; the decomposition of the equivalent variation contains a nuisance term. We find a further defect, that the upper-level demand equations are invalid. We revise the model to remove these defects.

description: As manufacturing tariffs have fallen worldwide, the focus of free trade agreements has shifted towards other issues, including: rules governing foreign investment, e-commerce regulations, trade in services, harmonization of technical standards, sanitary and phyto-sanitary regulations, and the streamlining of customs procedures. Japan and Singapore are undertaking negotiations over this kind of "new-age" FTA. The purpose of this paper is to evaluate the impact of the FTA on production, consumption, trade, international investment flows, GDP and welfare. We use a modified version of the dynamic GTAP model, which is well-suited to capturing the impact of this new-age FTA over both the short run and the longer run.
