description: Abstract

The present investigation, utilizing a quantitative research approach, focused on a sample of 393 employees from selected construction companies in Kuwait City. The primary data collection instrument employed was a questionnaire, and a total of 433 questionnaires were returned, resulting in an impressive response rate of 61.85% The study utilized advanced statistical methods, including SPSS, SEM, and AMOS, to analyse the gathered data. This study delved into the effects of organizational justice dimensions and explored the mediating role of job satisfaction in employees' intention to leave their jobs, finding empirical support for these relationships. The research specifically examined and verified the mediating effects of job satisfaction in the association between organizational justice dimensions and the intention to leave. The significance of this study lies in its ability to propose and validate a plausible sequence of factors influencing employees' intentions to leave their jobs, building upon established relationships between these variables from prior research. The findings highlight that organizational justice, as an external factor, significantly impacts individuals' intentions to leave the organization. The measurement model analysis revealed a statistically significant relationship between organizational justice and employees' intention to leave. Coefficient tests further demonstrated a significant correlation between diminished aspects of organizational fairness and an elevated intention to leave. Conversely, high levels of organizational justice were positively correlated with employees expressing an intention to leave based on the achieved level of job satisfaction. This study contributes to the understanding of the complex dynamics between organizational justice, job satisfaction, and employees' intentions to leave, specifically within the context of construction companies in Kuwait. The findings offer valuable insights for both researchers and practitioners in managing and retaining human capital in this sector. The analysis also considers the implications and limitations associated with the study's findings, providing a comprehensive perspective on the research outcomes.

description: Background— The manifestations and associated outcomes of patients with Coronavirus disease 2019 (COVID-19) are not well studied in large studies. To understand how the COVID-19 affects, and is affected by, cardiovascular conditions, larger and more diverse patient samples are necessary. A better understanding of how the disease interacts with pre-existing risk factors and COVID-19 induced complications may improve the ability of clinicians to provide informed care.Methods— A Cerner COVID-19 deidentified dataset based on electronic medical records in the Cerner Real-World Dataset is available to researchers. Data analytics pipelines are used to select study populations and identify risk factors, co-morbidities, and outcomes in patients with COVID-19 with various manifestations.Settings— A total of 54 healthcare facilities across the United States for the April 2020 release.Participants— Patients with a minimum of one emergency department (ED) visit, who were admitted for observation, or had an inpatient encounter with a diagnosis code that could be associated with COVID-19 exposure or infection, or those with a positive laboratory result for COVID-19.Intervention— Standard care as per institution.Main data elements— The encounters include pharmacy, clinical and microbiology laboratory, admission, and billing information. The patient population can be identified using the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) primary or secondary diagnosis codes and procedures can be identified using Procedure Coding System(ICD-10-PCS) and Current Procedural Terminology (CPT) codes.Conclusions— The Cerner COVID-19 deidentified dataset provides data from a large cohort of COVID-19 patients, which may increase the ability to address gaps in current knowledge regarding how the disease affects and is affected by cardiovascular conditions

description: Ion-trap quantum computers offer a large number of possible qubit couplings, each of which requires individual calibration and can be misconfigured. To enhance the duty cycle of an ion trap, we develop a strategy that diagnoses individual miscalibrated couplings using only log-many tests. This strategy is validated on a commercial ion-trap quantum computer, where we illustrate the process of debugging faulty quantum gates. Our methodology provides a scalable pathway towards fault detections on a larger scale ion-trap quantum computers, confirmed by simulations up to 32 qubits.

description: Lifetimes of low-spin excited states in $^{98}$Zr were measured using the recoil-distance Doppler-shift technique and the Doppler-shift attenuation method. The nucleus of interest was populated in a $^{96}$Zr($^{18}$O,$^{16}$O)$^{98}$Zr two-neutron transfer reaction at the Cologne FN Tandem accelerator. Lifetimes of six low-spin excited states, of which four are unknown, were measured. The deduced $B(E2)$ values were compared with Monte Carlo shell model and interacting boson model with configuration mixing calculations. Both approaches reproduce well most of the data but leave challenging questions regarding the structure of some low lying states.

description: Triple-negative breast cancer (TNBC) is of great concern due to its aggressiveness and lack of targeted therapy. For these reasons, TNBC is one of the main causes of death in women, mainly due to metastases. Tumor dissemination has highlighted a set of possible targets, with extensive research into new single-target drugs, in addition to drug repurposing strategies, being undertaken to discover new classes of potential inhibitors of metastasis. The authors here describe the main proposed targets and the bases of their pharmacological inhibition with different chemical compounds. The authors also discuss the state-of-the-art from the latest clinical trials and highlight other potential targets for metastatic TNBC. In the last decade, oncology research has changed its focus from primary tumors to moving tumor cells, their products, and to the secondary tumor and its surroundings, for the purpose of finding targets to treat metastasis. Consequently, our comprehension of the complexity of the metastatic process has increased drastically, with, furthermore, the discovery of new potential targets. Although promising, the wide range of strategies is still not effective to suppress TNBC metastasis in terms of increasing patient survival or decreasing the number of metastases. Treating or preventing metastasis continues to be a great challenge.

Regulatory phosphorylations on the eukaryotic elongation factor 1A mediated by RAF kinases
Creators: name: Sanges, Carmen
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: The elongation factor 1A has a crucial role in protein biosynthesis. EF1A belongs to the GTP-binding family of proteins and is able to deliver the aa-tRNA to the A-site of the ribosome because of its GTPase activity. Higher eukaryotes express two tissue specific isoforms of EF1A. In the last years, these isoforms were found to be involved in several different processes like senescence, apoptosis and transformation. In particular EF1A2 is overexpressed in several tumor cells and participates in drug resistence processes. Previous experiments in H1355 cells demonstrated that IFN treatment results in an antiapoptotical answer during which EF1A2 is increasingly expressed due to its RAF kinase mediated phosphorylation. As this interaction establishes a new link between the mitogenic cascade and protein biosynthesis, in vitro kinase assays were performed in presence of B- and C-RAF kinase and recombinant EF1A1/2 to investigate this important interaction. Mass spectrometry analysis identified treonine 88 (exclusively mediated by B-RAF) and serine 21 on EF1A1 and serine 21 on EF1A2 as B-/ and C-RAF mediated phosphorylation sites. Interestingly, serine 21 belongs to the consensus sequence of the GTP/GDP binding domain of EF1A. Its phosphorylation prevents the binding of the nucleotide suggesting that this potentially RAF mediated modification has a regulatory role affecting the function of the elongation factor.

description: Platelet hyperaggregation and hypercoagulation are associated with increase of thrombogenic risk, especially in patients with type 2 diabetes (T2D). High activity of P2Y12 receptor is found in T2D patients, exposing such patients to a prothrombotic condition. P2Y12 is a promising target for antiplatelet, but due to P2Y12 receptor constitutive activation, the clinical practical phenomena such as “clopidogrel resistance” are commonly occurring. In this study, we investigate the role of lncRNA on platelet activation. By lncRNA array, we screened thousands of differentially expressed lncRNA in megakaryocytes from T2D patients and confirmed that lncRNA metallothionein 1 pseudogene 3 (MT1P3) was significantly upregulated in megakaryocytes from T2D patients than in healthy controls. And we further investigate the biofunction of MT1P3 on platelet activation and the regulatory mechanism on p2y12. MT1P3 was positively correlated with p2y12 mRNA levels and promoted p2y12 expression by sponging miR-126. Knockdown of MT1P3 by siRNA reduced p2y12 expression, inhibiting platelet activation and aggregation in diabetes animal model. In conclusion, our findings identify MT1P3 as a key regulator in platelet activation by increasing p2y12 expression through sponging miR-126 under T2D condition. These findings may provide a new insight for managing platelet hyperactivity-related diseases.
title: Remember the medium! : film, medium specificity, and response-dependence
Creators: name: Torregrossa, Clotilde
Publisher: name: University of St Andrews

description: Medium specificity is a theory, or rather a cluster of arguments, in aesthetics that rests on the idea that media are the physical material that makes up artworks, and that this material contains specific and unique features capable of 1) differentiating media from one another, and 2) determining the aesthetic potential and goals of each medium. As such, medium specificity is essential for aestheticians interested in matters of aesthetic ontology and value. However, as Noël Carroll has vehemently and convincingly argued, the theory of medium specificity is inherently flawed and its many applications in art history ill-motivated. Famously, he concluded that we should ‘forget the medium’ entirely. In this thesis, I reject his conclusion and argue that reconstructing a theory of medium specificity, while taking Carroll’s objections into account, is possible. To do so, I offer a reconceptualization of the main theoretical components of medium specificity and ground this new theory in empirical research. I first redefine the medium not as the physical material that makes up artworks but as sets of practices – not the material itself but how one uses the material. I then show that what makes media specific and unique is not certain physical features, but the human responses, which can be empirically investigated, to the combination of practices that constitute media. This relation is one of response-dependence, albeit of a novel kind, which I develop by appealing to social metaphysics. The resulting theory is more complex but also much more flexible and fine-grained than the original and provides insight into a variety of current aesthetic theories.

Valutazione dell’efficacia e della sicurezza di nuovi approcci terapeutici in alcuni difetti congeniti del metabolismo

description: Negli ultimi anni grandi progressi sono stati effettuati per il trattamento di alcuni errori congeniti del metabolismo, al fine di migliorare la qualità di vita, la crescita e lo sviluppo dei pazienti affetti. Da sempre il trattamento delle LSD rappresenta una grande sfida per i medici coinvolti nel management dei pazienti affetti da tali patologie. In passato l’unica terapia possibile per le LSD era una terapia di supporto, mirata a combattere le complicanze associate alle LSD. Al contrario non era disponibile alcun approccio mirato alla correzione del difetto di base della malattia. Negli ultimi 20 anni, le maggiori conoscenze sulle basi molecolari e biochimiche di varie malattie da accumulo lisosomiale, e la disponibilità di nuove tecnologie hanno reso possibile l’introduzione e la sperimentazione, con risultati anche molto incoraggianti, di diverse strategie terapeutiche innovative quali la terapia enzimatica sostitutiva (Enzyme Replacement Therapy, ERT). Oltre alle malattie d’accumulo lisosmali, nuove strategie terapeutiche sono state sperimentate anche in altri errori congeniti del metabolismo, quali le aminoacidopatie, in particolare nelle iperfenilalaninemie. Storicamente, il trattamento della HPA è stato unicamente non-farmacologico e i pazienti affetti dovevano essere trattati con una dieta a ridotto contenuto di Phe entro le prime settimane di vita. È attualmente noto che il trattamento deve essere necessariamente continuato per tutta la vita. Sfortunatamente, la compliance alla terapia dietetica risulta essere sub-ottimale, e molti pazienti, in particolare gli adolescenti, non seguono o sospendono lo schema dietetico prescritto. Lo studio qui riportato è il risultato di quattro anni di ricerca effettuato nell’ambito del programma del Dottorato, sviluppato presso il Dipartimento di Pediatria dell’Università “Federico II” di Napoli da Novembre 2006 ad Ottobre 2010. Tale studio ha permesso la realizzazione di due progetti, incentrati su nuovi approcci terapeutici in due errori congeniti del metabolismo: la Mucopolisaccaridosi tipo I (MPS I) e le iperfenilalaninemia (HPA).

description: The always increasing demand in new transportation routes in urban area, in the last years, led to the need in increasing the present road transports; by then, the need to use the underground environment for new transportation lines became always more important. New underground lines started to be excavated in many of the largest cities in the world, leading to a large number of shallow and deep excavations in the urban environment.
Many tunnels, often located at relatively shallow depth from the ground surface, started to be excavated, inducing not negligible effects on the preexisting buildings. For such a reason, methods directed to the induced tunnelling effects prediction were developed on the basis of empirical data collected all over the years. Despite such empirical methods resulted very useful and reliable for the designing process of a tunnel line, as to predict the tunnel induced displacements on the ground surface, they base on very simplified hypothesis, neglecting important phenomena such as the soil-tunnel-buildings interaction and considering in a simplified way the excavation technique influence. Indeed data collected from literature, demonstrated how the improvements in technologies in the last years allowed an important reductions in induced displacements on the ground surface. For a such a reason numerical analysis of the excavation technique influence on tunnelling induced displacements, became always more significant.
Thus, the purpose of this research is to define the importance of excavations technologies, in terms of tunnelling induced effects on the ground surface, inspired by the current construction process of the Line 6 tunnel in Naples. For this purpose, a number of numerical analyses, by means Finite Element codes, were performed as to simulate the tunnel excavation process, and to carry on a parametric study on the technology influence on the induced effects, finally compared to results of a similar parametric study concerning the geotechnical properties of the soils affected by the excavation. Results of such analyses were then used to back-analyze monitoring data collected during the Line 6 tunnelling process.
Modelling, Analysis, Control and Experimental Validation of Electromechanical Valve Actuators in Automotive Systems

Year: 2011

description: This Thesis is concerned with the modelling, analysis and control of novel mechatronic valve actuators for automotive systems, specifically, the control of the mechanical valves to intake and exhaust gases in Internal Combustion Engines (ICE). Scientific studies have shown that significant benefits in terms of engine efficiency and emissions can be obtained through the adoption of variable valve actuation. Current engine technology are based on the use of a mechanical driven camshaft, which is a no flexible device due to its strongly coupling to crankshaft position. Thus, it is not possible to adjust or adapt in real time the valve features according to the engine working conditions. Hence, there is the need of designing innovative mechanisms to actuate the engine valves. In so doing, traditional mechanical cam systems can be removed and a train of single actuated valves is incorporated into the ICE, leading to the development of camless engine technology. Electro-Mechanical Valve Actuators (EMVA) have been considered as one of the most promising technological solutions to develop this novel engine technology. To achieve all the potential benefits of the EMVA systems, two crucial control problems have to be tackled and solved efficiently: the control of the first lift manoeuvre, known as First Catching Control (FCC) problem, and the control of the valve seating velocity, known as Soft Landing Control (SLC) problem. The thesis shows that the analysis and control of the EMVA device can be successfully addressed in the framework of non-smooth dynamical system and nonlinear control theory, furthermore, the tuning of non linear controllers can be successfully done by using closed loop bifurcation diagram analysis. In particular, a non-smooth mathematical model is proposed, estimated and validated experimentally. A novel Key-on controller is proposed to solve the FCC control problem, while a combined feedforward-sliding mode controller is proposed to solve the SLC control problem. The proposed control approaches have been tested numerically and validated on an experimental setup, leading to successful results.

description: Little is known about the spin-flip diffusion length $l_{\rm sf}$, one of the most important material parameters in the field of spintronics. We use a density-functional-theory based scattering approach to determine values of $l_{\rm sf}$ that result from electron-phonon scattering as a function of temperature for all 5d transition metal elements. $l_{\rm sf}$ does not decrease monotonically with the atomic number Z but is found to be inversely proportional to the density of states at the Fermi level. By using the same local current methodology to calculate the spin Hall angle $Θ_{\rm sH}$ that characterizes the efficiency of the spin Hall effect, we show that the products $ρ(T)l_{\rm sf}(T)$ and $Θ_{\rm sH}(T)l_{\rm sf}(T)$ are constant.

description: Ischemic stroke and encephalitis have been reported in patients infected with SARS-CoV-2. We describe a case of a 60-year old woman with posterior reversible encephalopathy syndrome (PRES) associated with SARS-CoV-2 antibodies. She had classic laboratory abnormalities indicating multi-organ involvement. The MRI Brain revealed classical PRES findings on T2-weighted and FLAIR sequences and MR spectroscopy confirmed findings of PRES. Repeat MRI brain at one-month follow-up confirmed PRES findings based on signal resolution and identified an infarct in addition to PRES. Most of the laboratory abnormalities resolved at one-month follow-up. The inflammatory changes implicated in PRES including TNF-α, IL-1, IFN-Υ and IL-6 have been identified in SARS-CoV-2 patients in other case reports. We hypothesize that monoclonal antibody therapies targeting these inflammatory molecules that consequently disrupt the blood brain barrier may be useful in patients with PRES associated with SARS-CoV-2 infection.

description: We discover chiral phonons at the lowest-energy bands in moiré superlattices. The moiré chiral phonons we uncover are the collective excitations of the stacking domains. Their origin is uniquely attributed to the stacking configurations whose interlayer binding energy breaks the $C_{2z}$ symmetry on the moiré length scale. Within elastic theory, we use a general symmetry analysis to provide a complete classification of van der Waals heterostructures in respect to hosting moiré chiral phonons and show the calculation for twisted MoS$_2$ as an example. We present a low-energy effective model to qualitatively understand the moiré chiral phonons and show that it captures the essential physics remarkably well. Our result potentially opens up new possibilities in phononic twistronics as the moiré chiral phonons have high tunability, moiré scale wavelengths, excitation energies in only a few meV, and can possibly be mechanically excited.

description: The estimation of rare K decay matrix-elements from Kl3 experimental data is extended beyond LO in Chiral Perturbation Theory. Isospin-breaking effects at NLO (and partially NNLO) in the ChPT expansion, as well as QED radiative corrections are now accounted for. The analysis relies mainly on the cleanness of two specific ratios of form-factors, for which the theoretical control is excellent. As a result, the uncertainties on the K+ --> pi+ nu nubar and KL --> pi0 nu nubar matrix-elements are reduced by a factor of about 7 and 4, respectively, and similarly for the direct CP-violating contribution to KL --> pi0 l+ l-. They could be reduced even further with better experimental data for the Kl3 slopes and the K+l3 branching ratios. As a result, the non-parametric errors for B(K --> pi nu nubar) and for the direct CP-violating contributions to B(KL --> pi0 l+ l-) are now completely dominated by those on the short-distance physics.

description: It is well known that Pfaffian formulas for eigenvalue correlations are useful in the analysis of real and quaternion random matrices. Moreover the parametric correlations in the crossover to complex random matrices are evaluated in the forms of Pfaffians. In this article, we review the formulations and applications of Pfaffian formulas. For that purpose, we first present the general Pfaffian expressions in terms of the corresponding skew orthogonal polynomials. Then we clarify the relation to Eynard and Mehta's determinant formula for hermitian matrix models and explain how the evaluation is simplified in the cases related to the classical orthogonal polynomials. Applications of Pfaffian formulas to random matrix theory and other fields are also mentioned.

description: The evaporation coefficients of water in air and nitrogen were found as a function of temperature, by studying the evaporation of pure water droplet. The droplet was levitated in an electrodynamic trap placed in a climatic chamber maintaining atmospheric pressure. Droplet radius evolution and evaporation dynamics were studied with high precision by analyzing the angle-resolved light scattering Mie interference patterns. A model of quasi-stationary droplet evolution, accounting for the kinetic effects near the droplet surface was applied. In particular, the effect of thermal effusion (a short range analogue of thermal diffusion) was discussed and accounted for. The evaporation coefficient αin air and in nitrogen were found equal. αwas found to decrease from ~ 0.18 to ~ 0.13 for the temperature range from 273.1 K to 293.1 K and follow the trend given by Arrhenius formula. The agreement with condensation coefficient values obtained with essentially different method by Li et al.[1] was found excellent. The comparison of experimental conditions used in both methods revealed no dependence of evaporation/condensation coefficient upon droplet charge nor ambient gas pressure within experimental parameters range. The average value of thermal accommodation coefficient over the same temperature range was found to be 1 \pm 0.05.

description: We relate the entropy of entanglement of ensembles of random vectors to their generalized fractal dimensions. Expanding the von Neumann entropy around its maximum we show that the first order only depends on the participation ratio, while higher orders involve other multifractal exponents. These results can be applied to entanglement behavior near the Anderson transition.

description: Background— Headaches and dizziness may occur in patients with coronavirus disease 2019 (COVID-19).Objective— To determine the prevalence and clinical characteristics of headaches and dizziness in patients with COVID-19.Design— A questionnaire was used for patients with confirmed COVID-19.Methods— The questionnaire inquired about baseline characteristics and clinical features of the new onset headaches or dizziness. The temporal relationship between various features of headache and dizziness and onset of classical COVID-19 symptoms (cough, dyspnea, and fever) were determined. The severity of headaches was assessed on a numeric rating a scale of 0-10.Results— A total of 88 (21.6%) of 407 patients reported new headaches with diagnosis of COVID-19. The median severity of headaches on average and when most severe based on the were 5 and 6, respectively. A total of 75 (85.2%) patients with headaches required over the counter medications and 60 (68.2%) reported decreased functional ability secondary to their headaches. A total of 20.5% reported that headaches started prior to classical symptoms, 8% reported that headaches were worst and 11.4% reported that headaches had resolved prior to onset of classical symptoms of COVID-19. A total of 21 (5.2%) of 407 patients reported that they had dizziness with COVID-19; 18 of 21 patients reported episodic dizziness. Of the 21 patients with dizziness, 23.8% reported that dizziness started prior to onset classical symptoms of COVID-19.Conclusions— Headaches and dizziness were relatively frequent in COVID-19 patients and often preceded the classical symptoms. Headaches often require medication and impair functional ability in COVID-19 patients.

description: Baryonic feedback effects consist of a major systematic for upcoming weak-lensing and galaxy-clustering surveys. In this paper, we present an emulator for the baryonic suppression of the matter power spectrum. The emulator is based on the baryonification model, containing seven free parameters that are connected to the gas profiles and stellar abundances in haloes. We show that with the baryonic emulator, we can not only recover the power spectra of hydro-dynamical simulations at sub-percent precision but also establish a connection between the baryonic suppression of the power spectrum and the gas and stellar fractions in haloes. This connection allows us to predict the expected deviation from a dark-matter-only power spectrum using measured X-ray gas fractions of galaxy groups and clusters. With these measurements, we constrain the suppression to exceed the percent-level at k = 0.1-0.4 h/Mpc and to reach a maximum of 20-28 percent at around k = 7 h/Mpc (68 percent confidence level). As a further step, we also perform a detailed parameter study and we present a minimum set of four baryonic parameters that are required to recover the scale and redshift dependence observed in hydro-dynamical simulations.

description: We investigate all N=2 supersymmetric IIB supergravity backgrounds with non-vanishing five-form flux. The Killing spinors have stability subgroups $Spin(7)\ltimes\bR^8$, $SU(4)\ltimes\bR^8$ and $G_2$. In the $SU(4)\ltimes\bR^8$ case, two different types of geometry arise depending on whether the Killing spinors are generic or pure. In both cases, the backgrounds admit a null Killing vector field which leaves invariant the $SU(4)\ltimes \bR^8$ structure, and an almost complex structure in the directions transverse to the lightcone. In the generic case, the twist of the vector field is trivial but the almost complex structure is non-integrable, while in the pure case the twist is non-trivial but the almost complex structure is integrable and associated with a relatively balanced Hermitian structure. The $G_2$ backgrounds admit a time-like Killing vector field and two spacelike closed one-forms, and the seven directions transverse to these admit a co-symplectic $G_2$ structure. The $Spin(7)\ltimes\bR^8$ backgrounds are pp-waves propagating in an eight-dimensional manifold with holonomy $Spin(7)$. In addition we show that all the supersymmetric solutions of simple five-dimensional supergravity with a time-like Killing vector field, which include the $AdS_5$ black holes, lift to $SU(4)\ltimes\bR^8$ pure Killing spinor IIB backgrounds. We also show that the LLM solution is associated with a co-symplectic co-homogeneity one $G_2$ manifold which has principal orbit $S^3\times S^3$.

The Evolutive Nature of Translation and Teaching Workflow: Textometric Analysis of Multiple Revision Cycles in a Simulated Website Translation Project

Year: 2023

description: In this paper, we explore the practical and theoretical status of revision in the context of a Masters-level website translation project integrating machine translation (MT) for teaching purposes. We use textometric analysis to explore the nature of modifications made at each of the different stages of revision during the lifetime of one particular project. Computation of characteristic elements and Correspondence Analysis (CA) reveal regular patterns of linguistic intervention, with significant differences observed between the initial stages of the project (MT-EN0 generated by SYSTRAN Pure Neural Machine Translation and post-edited MT-EN1) and subsequent revision cycles. We combine quantitative and qualitative research methods to study characteristic revision patterns in different project cycles (chronological textual series). While some of these patterns represent unpredictable “punctual” edits, the majority are “progressive”, involving modifications that are predictable or gradually built up throughout the project. More generally, it appears that different types of revision closely mirror the guidelines that are presented to students during the teaching workflow. This observation leads us to posit an “evolutive” view of the translation project: just as each webpage in the project has to undergo several cycles of revision, so each stage of revision needs to be carefully primed during the preparation of the project with the clients as well as the students.

description: Quadratic curvature Gauss-Bonnet gravity may be the solution to the dark energy problem, but a large coupling strength is required. This can lead to conflict with laboratory and planetary tests of Newton's law, as well as light bending. The corresponding constraints are derived. If applied directly to cosmological scales, the resulting bound on the density fraction is |Omega_GB| < 3.6 x 10^-32.

description: The unfree gauge symmetry implies that gauge variation of the action functional vanishes provided for the gauge parameters are restricted by the differential equations. The unfree gauge symmetry is shown to lead to the global conserved quantities whose on shell values are defined by the asymptotics of the fields or data on the lower dimension surface, or even at the point of the space-time, rather than Cauchy hyper-surface. The most known example of such quantity is the cosmological constant of unimodular gravity. More examples are provided in the article for the higher spin gravity analogues of the cosmological constant. Any action enjoying the unfree gauge symmetry is demonstrated to admit the alternative form of gauge symmetry with the higher order derivatives of unrestricted gauge parameters. The higher order gauge symmetry is reducible in general, even if the unfree symmetry is not. The relationship is detailed between these two forms of gauge symmetry in the constrained Hamiltonian formalism. The local map is shown to exist from the unfree gauge algebra to the reducible higher order one, while the inverse map is non-local, in general. The Hamiltonian BFV-BRST formalism is studied for both forms of the gauge symmetry. These two Hamiltonian formalisms are shown connected by canonical transformation involving the ghosts. The generating function is local for the transformation, though the transformation as such is not local, in general. Hence, these two local BRST complexes are not quasi-isomorphic in the sense that their local BRST-cohomology groups can be different. This difference in particular concerns the global conserved quantities. From the standpoint of the BRST complex for unfree gauge symmetry, these quantities are BRST-exact, while for the alternative complex, these quantities are the non-trivial co-cycles.

description: This paper describes the design goals and engineering efforts that led to the realization of AMBER (Astronomical Multi BEam combineR) and to the achievement of its present performance. On the basis of the general instrumental concept, AMBER was decomposed into modules whose functions and detailed characteristics are given. Emphasis is put on the spatial filtering system, a key element of the instrument. We established a budget for transmission and contrast degradation through the different modules, and made the detailed optical design. The latter confirmed the overall performance of the instrument and defined the exact implementation of the AMBER optics. The performance was assessed with laboratory measurements and commissionings at the VLTI, in terms of spectral coverage and resolution, instrumental contrast higher than 0.80, minimum magnitude of 11 in K, absolute visibility accuracy of 1%, and differential phase stability of 1E-3 rad over one minute.

description: We extract local current distributions from interatomic currents calculated using a fully relativistic quantum mechanical scattering formalism by interpolation onto a three-dimensional grid. The method is illustrated with calculations for Pt$|$Ir and Pt$|$Au multilayers as well as for thin films of Pt and Au that include temperature-dependent lattice disorder. The current flow is studied in the "classical" and "Knudsen" limits determined by the sample thickness relative to the mean free path $λ$, introducing current streamlines to visualize the results. For periodic multilayers, our results in the classical limit reveal that transport inside a metal can be described using a single value of resistivity $ρ$ combined with a linear variation of $ρ$ at the interface while the Knudsen limit indicates a strong spatial dependence of $ρ$ inside a metal and an anomalous dip of the current density at the interface which is accentuated in a region where transient shunting persists.
