description: Boehmite, an aluminum oxide hydroxide $γ$-AlO(OH), is broadly used in the form of particulate dispersions in industrial applications, e.g., for the fabrication of ceramics and catalyst supports or as a binder for extrusion processes. Under acidic conditions, colloidal boehmite dispersions at rest form gels, i.e., space-spanning percolated networks that behave as soft solids at rest, and yet yield and flow like liquids under large enough deformations. Like many other colloidal gels, the solid-like properties of boehmite gels at rest are very sensitive to their previous mechanical history. Our recent work [Sudreau et al., J. Rheol. 66, 91-104 (2022), and Phys. Rev. Material 6, L042601 (2022)] has revealed such \textit{memory effects}, where the shear experienced prior to flow cessation drives the elasticity of boehmite gels: while gels formed following application of a shear rate $\dotγ_{\rm p}$ larger than a critical value $\dotγ_{\rm c}$ are insensitive to shear history, gels formed after application of $\dotγ_{\rm p}<\dotγ_{\rm c}$ display reinforced viscoelastic properties and non-negligible residual stresses. Here, we provide a microstructural scenario for these striking observations by coupling rheometry and small-angle X-ray scattering. Time-resolved measurements for $\dotγ_{\rm p} <\dotγ_{\rm c}$ show that scattering patterns develop an anisotropic shape that persists upon flow cessation, whereas gels exposed to $\dotγ_{\rm p}>\dotγ_{\rm c}$ display isotropic scattering patterns upon flow cessation. Moreover, as the shear rate applied prior to flow cessation is decreased below $\dotγ_{\rm c}$, the level of anisotropy frozen in the sample microstructure grows similarly to the viscoelastic properties, thus providing a direct link between mechanical reinforcement and flow-induced microstructural anisotropy.

description: L'osteoartrite (OA) è una delle principali cause di dolore cronico e deterioramento articolare, che influisce significativamente sulla qualità della vita. Hanno un ruolo nella sua patogenesi i fibroblasti (FLS), che producono che rispondono a citochine infiammatorie. Il segnale del calcio (Ca2+) influenza la secrezione di citochine infiammatorie e altri fattori in tutte le cellule, inclusi gli FLS. Pertanto, la modualzione del Ca2+ negli FLS da parte di SOCE potrebbe rappresentare una strategia promettente per ridurre l'infiammazione nell'OA. L'obiettivo di questo studio è indagare gli effetti un nuovo modulatore negativo del SOCE (CIC-39) e di un farmaco commerciale (metotrexato (MTX) usato per il trattamento delle malattie reumatiche su un modello in vitro 2D di OA-FLS infiammato, in cui gli FLS, derivati da biopsie sinoviali di pazienti con OA, sono stati stimolati con un cocktail di citochine proinfiammatorie (IL-1β, IL-6 e TNF-α) ed i livelli di espressione delle citochine proinfiammatorie sono stati valutati mediante qRT-PCR. I nostri risultati hanno mostrato che CIC-39 sembra ridurre la secrezione di TNF-α, a e futuri esperimenti, con un maggior numero di campioni, sono necessari per confermare questo risultato.

ABSTRACTClimate change is producing a radical mutation in the world of design, inviting designers to change their attitude from designers of the present to facilitators of the future, placing them before the challenge of planning the unexpected of a territorial structure that we know will change drastically, but in ways not actually foreseeable. The following research focuses on this change of attitude, probing the attention on the issue of sea level rise through a compositional and design exploration. If technical solutions such as dams and resistant waterfront are activated on one side, on the other it is necessary to identify coexistence strategies with the variation of the sea, especially for those peripheral areas where it is not possible to foresee heavy infrastructure investments. The challenge is to imagine new aquatic landscapes of the future, to create both the basis for dialogue and a reference tool for change. For this purpose, the research started by wondering what the constitution of the current landscape is, how it can be defined and what the bases are for an imaginary of future water landscapes. The proposed solution is that of exploration through the representation of a compositional catalog of the water space, which allows to sample the current elements of which the territory is composed, and then, through the instruments of drawing and composition, probing its evolution according to the scenario of sea level rise. The result is therefore that of a large table of elements that speaks of the territory and its transformation, of the current relationship between architecture and water and of what could come, an orientation abacus for the composition of the future water landscape.

description: CuI/TEMPO (TEMPO=2,2,6,6-tetramethylpiperidinyloxyl) catalyst systems are versatile catalysts for aerobic alcohol oxidation reactions to selectively yield aldehydes. However, several aspects of the mechanism are yet unresolved, mainly because of the lack of identification of any reactive intermediates. Herein, we report the synthesis and characterization of a dinuclear [L12Cu2]2+ complex 1, which in presence of TEMPO can couple the catalytic 4 H+/4 e− reduction of O2 to water to the oxidation of benzylic and aliphatic alcohols. The mechanisms of the O2-reduction and alcohol oxidation reactions have been clarified by the spectroscopic detection of the reactive intermediates in the gas and condensed phases, as well as by kinetic studies on each step in the catalytic cycles. Bis(μ-oxo)dicopper(III) (2) and bis(μ-hydroxo)dicopper(II) species 3 are shown as viable reactants in oxidation catalysis. The present study provides deep mechanistic insight into the aerobic oxidation of alcohols that should serve as a valuable foundation for ongoing efforts dedicated towards the understanding of transition-metal catalysts involving redox-active organic cocatalysts.

description: We present and analyze a near infrared(NIR) spectrum of the under-luminous Type Ia supernova SN~2020qxp/ASASSN-20jq obtained with NIRES at the Keck Observatory 191 days after B-band maximum. The spectrum is dominated by a number of broad emission features including the [FeII] at 1.644mu which is highly asymmetric with a tilted top and a peak red-shifted by ~2,000km/s. In comparison with 2-D non-LTE synthetic spectra computed from 3-D simulations of off-center delayed-detonation Chandrasekhar-mass white-dwarf(WD) models, we find good agreement between the observed lines and the synthetic profiles, and are able to unravel the structure of the progenitor's envelope. We find that the size and tilt of the [Fe II] 1.644mu-profile (in velocity space) is an effective way to determine the location of an off-center delayed-detonation transition (DDT) and the viewing angle, and it requires a WD with a high central density of ~4E9$g/cm^3$. We also tentatively identify a stable Ni feature around 1.9mu characterized by a `pot-belly' profile that is slightly offset with respect to the kinematic center. In the case of SN~2020qxp/ASASSN-20jq, we estimate that the location of the DDT is ~0.3M(WD) off-center, which gives rise to an asymmetric distribution of the underlying ejecta. We also demonstrate that low-luminosity and high-density WD SNIa progenitors exhibit a very strong overlap of Ca and 56Ni in physical space. This results in the formation of a prevalent [Ca II] 0.73mu emission feature, which is sensitive to asymmetry effects. Our findings are discussed within the context of alternative scenarios, including off-center C/O detonations in He-triggered sub-M(Ch)-WDs and the direct collision of two WDs. Snapshot programs with Gemini/Keck/VLT/ELT class instruments and our spectropolarimetry program are complementary to mid-IR spectra by JWST.

description: Topologically non-trivial vacuum structure in gravity models with Cartan variables (vielbein and contortion) is considered. We study the possibility of vacuum space-time tunneling in Einstein gravity assuming that the vielbein may play a fundamental role in quantum gravitational phenomena. It has been shown that in the case of RP3 space topology the tunneling between non-trivial topological vacuums can be realized by means of Eguchi-Hanson gravitational instanton. In Riemann-Cartan geometric approach to quantum gravity the vacuum tunneling can be provided by means of contortion quantum fluctuations. We define double self-duality condition for the contortion and give explicit self-dual configurations which can contribute to vacuum tunneling amplitude.

description: Background and Purpose: Brain perfusion measurement in the subacute phase of stroke may support therapeutic decisions. We evaluated whether arterial spin labeling (ASL), a noninvasive perfusion imaging technique based on magnetic resonance imaging (MRI), adds diagnostic and prognostic benefit to diffusion-weighted imaging (DWI) in subacute stroke. Methods: In a single-center imaging study, patients with DWI lesion(s) in the middle cerebral artery (MCA) territory were included. Onset to imaging time was ≤ 7 days and imaging included ASL and DWI sequences. Qualitative (standardized visual analysis) and quantitative perfusion analyses (region of interest analysis) were performed. Dichotomized early outcome (modified Rankin Scale [mRS] 0-2 vs. 3-6) was analyzed in two logistic regression models. Model 1 included DWI lesion volume, age, vascular pathology, admission NIHSS, and acute stroke treatment as covariates. Model 2 added the ASL-based perfusion pattern to Model 1. Receiver-operating-characteristic (ROC) and area-under-the-curve (AUC) were calculated for both models to assess their predictive power. The likelihood-ratio-test compared both models. Results: Thirty-eight patients were included (median age 70 years, admission NIHSS 4, onset to imaging time 67 hr, discharge mRS 2). Qualitative perfusion analysis yielded additional diagnostic information in 84% of the patients. In the quantitative analysis, AUC for outcome prediction was 0.88 (95% CI 0.77-0.99) for Model 1 and 0.97 (95% CI 0.91-1.00) for Model 2. Inclusion of perfusion data significantly improved performance and outcome prediction (p = 0.002) of stroke imaging. Conclusions: In patients with subacute stroke, our study showed that adding perfusion imaging to structural imaging and clinical data significantly improved outcome prediction. This highlights the usefulness of ASL and noninvasive perfusion biomarkers in stroke diagnosis and management.

description: We investigate effects of optical lattice potential in one- and two-dimensional two-component trapped Fermi gases with population imbalances. Using the exact diagonalization and the density matrix renormalization group methods complementarily, we calculate the atom density profile from the ground state many-body wavefunction as a function of attractive interaction strength for various population imbalances. The numerical results reveal that although a phase separation between the superfluid core and the shell cloud of excess atoms occurs as observed in experiments without the optical lattice, the population imbalance generally remains in the core region in contrast to the non-lattice cases. The essence of the numerical results in a strong attractive regime can be explained by an effective model composed of Cooper pairs and excess major fermions.

We introduce an invariant for the elements of $QI(\mathbb{R_{+}})$ and split it into smaller units. We give an almost characterization of the elements of these units. We also show that a quotient of $QI(\mathbb{R_{+}})$ gives an example of a left-orderable group which is not locally indicable.

ABSTRACTOver the past century, population growth and climate change have affected most cities in developing countries, being damaged extensively at different scales. For instance, in Iran, the historical sustainable blue-green infrastructure (BGI) is under pressing pressure. However, sustainable BGI could support the environmental, social, and economic sustainability and mitigate as well as adapt to climate change. Qazvin, the historical Persian garden city in the middle of Iran, is a valuable sample of sustainable adaptation to drought and water shortage. Due to the urban development process, population growth, and climate change during the last century, Qazvin has lost a significant part of its historical blue-green infrastructure. This paper aims to assess the effects of population growth and climate change on sustainable BGI in Qazvin and offer appropriate solutions for conserving and rehabilitating sustainable BGI. The research methodology is the case study method. Hence, the principles of environmental, social, and economic sustainability dimensions in the blue-green infrastructure are identified. Data related to population growth, climate change, and urban development in Qazvin are collected, and the effects of these factors on sustainable BGI are analyzed. Finally, the proposed mechanism implementing the sustainable BGI adapted to climate change and urban development has been introduced.
Linking Uranus' temperature profile to wind-induced magnetic fields

description: The low luminosity of Uranus is still a puzzling phenomenon and has key implications for the thermal and compositional gradients within the planet. Recent studies have shown that planetary volatiles become ionically conducting under conditions that are present in the ice giants. Rapidly growing electrical conductivity with increasing depth would couple zonal flows to the background magnetic field in the planets, inducing poloidal and toroidal field perturbations $\mathbf{B}^ω = \mathbf{B}^ω_P + \mathbf{B}^ω_T$ via the $ω$-effect. Toroidal perturbations $\mathbf{B}^ω_T$ are expected to diffuse downwards and produce poloidal fields $\mathbf{B}^α_P$ through turbulent convection via the $α$-effect, comparable in strength to those of the $ω$-effect; $\mathbf{B}^ω_P$. To estimate the strength of poloidal field perturbations for various Uranus models in the literature, we generate wind decay profiles based on Ohmic dissipation constraints assuming an ionically conducting H$_2$-He-H$_2$O interior. Due to the higher metallicities in outer regions of hot Uranus models, zonal winds need to decay to $\sim$0.1% of their surface values in the outer 1% of Uranus to admit decay solutions in the Ohmic framework. Our estimates suggest that colder Uranus models could potentially have poloidal field perturbations that reach up to $\mathcal{O}(0.1)$ of the background magnetic field in the most extreme case. The possible existence of poloidal field perturbations spatially correlated with Uranus' zonal flows could be used to constrain Uranus' interior structure, and presents a further case for the $\textit{in situ}$ exploration of Uranus.

description: The $σ$ profile is presented as a tool to analyze the organization of systems at different scales, and how this organization changes in time. Describing structures at different scales as goal-oriented agents, one can define $σ\in [0,1]$ ("satisfaction") as the degree to which the goals of each agent at each scale have been met. $σ$ reflects the organization degree at that scale. The $σ$ profile of a system shows the satisfaction at different scales, with the possibility to study their dependencies and evolution. It can also be used to extend game theoretic models. A general tendency on the evolution of complexity and cooperation naturally follows from the $σ$ profile. Experiments on a virtual ecosystem are used as illustration.

description: The objective of this critical review is to provide an overview of how emerging bioanalytical techniques are expanding our understanding of the complex physicochemical nature of virus interactions with host cell surfaces. Herein, selected model viruses representing both non-enveloped (simian virus 40 and human norovirus) and enveloped (influenza A virus, human herpes simplex virus, and human immunodeficiency virus type 1) viruses are highlighted. The technologies covered utilize a wide range of cell membrane mimics, from supported lipid bilayers (SLBs) containing a single purified host membrane component to SLBs derived from the plasma membrane of a target cell, which can be compared with live-cell experiments to better understand the role of individual interaction pairs in virus attachment and entry. These platforms are used to quantify binding strengths, residence times, diffusion characteristics, and binding kinetics down to the single virus particle and single receptor, and even to provide assessments of multivalent interactions. The technologies covered herein are surface plasmon resonance (SPR), quartz crystal microbalance with dissipation (QCM-D), dynamic force spectroscopy (DFS), total internal reflection fluorescence (TIRF) microscopy combined with equilibrium fluctuation analysis (EFA) and single particle tracking (SPT), and finally confocal microscopy using multi-labeling techniques to visualize entry of individual virus particles in live cells. Considering the growing scientific and societal needs for untangling, and interfering with, the complex mechanisms of virus binding and entry, we hope that this review will stimulate the community to implement these emerging tools and strategies in conjunction with more traditional methods. The gained knowledge will not only contribute to a better understanding of the virus biology, but may also facilitate the design of effective inhibitors to block virus entry.

Die empirische Grundlage liefert eine Fallstudie zur Teilhabe und zur Stärkung des sozialen Zusammenhalts durch kooperative Freiraumentwicklung in benachteiligten Quartieren. Obwohl der Themenkomplex „Experiment und Planung“ im urbanen Kontext in der jüngeren Vergangenheit verstärkt Aufmerksamkeit gefunden hat, mangelt es doch weiterhin an theoretischen Analysen und empirischen Untersuchungen. Hier wird daher zunächst auf das Verhältnis von Experiment und Planung aus methodologisch-methodischer Sicht eingegangen – im Hinblick auf die Ziele, die Art des Wissens und die Verfahren der Wissensproduktion, die Instrumente und Prozesse. Dann werden anhand der Fallstudie die inhaltlichen, instrumentellen und akteursbezogenen Dimensionen dieses Verhältnisses analysiert. Im Ergebnis zeigt sich, dass das Realexperimente der Stadtplanung durchaus Chancen eröffnen kann – in inhaltlicher Hinsicht die Produktion differenzierteren Ziel-, System- und Transformationswissens, in instrumenteller Hinsicht die Bereitstellung offenerer Beteiligungsformate, in akteursbezogener Hinsicht das Aufbrechen eingefahrener Governance-Arrangements. Ob dies wirklich als Chance begriffen wird, hängt jedoch vom lokalen Planungsobjekt und von der lokalen Planungskultur ab.

description: When very small particles are suspended in a fluid in motion, they tend to follow the flow. How such tracer particles are mixed, transported, and dispersed by turbulent flow has been successfully described by statistical models. Heavy particles, with mass densities larger than that of the carrying fluid, can detach from the flow. This results in preferential sampling, small-scale fractal clustering, and large collision velocities. To describe these effects of particle inertia, it is necessary to consider both particle positions and velocities in phase space. In recent years, statistical phase-space models have significantly contributed to our understanding of inertial-particle dynamics in turbulence. These models help to identify the key mechanisms and non-dimensional parameters governing the particle dynamics, and have made qualitative, and in some cases quantitative predictions. This article reviews statistical phase-space models for the dynamics of small, yet heavy, spherical particles in turbulence. We evaluate their effectiveness by comparing their predictions with results from numerical simulations and laboratory experiments, and summarise their successes and failures. Annu. Rev.

description: In this study, we focus on a static spherically symmetric $f(R)$ black hole spacetime characterized by a linear dark matter-related parameter. Our investigation delves into understanding the influence of different assumed values of this parameter on the observable characteristics of the black hole. To fulfill this task, we investigate the light deflection angles, which are inferred from direct analytical calculations of null geodesics.} To examine the black hole's properties further, we assume an optically thin accretion disk and explore various emission profiles. Additionally, we investigate the shadow cast by the illuminated black hole when affected by the disk. Furthermore, we simulate the brightness of an infalling spherical accretion in the context of silhouette imaging for the black hole. Our findings indicate that, except for some specific cases, the observed brightness of the accretion disk predominantly arises from direct emission, rather than lensing and photon rings. Moreover, we reveal that the linear dark parameter of the black hole significantly influences the shadow size and brightness. Our discussion covers both analytical and numerical approaches, and we utilize ray-tracing methods to produce accurate visualizations.

description: Background KDEL receptor helps establish cellular equilibrium in the early secretory pathway by recycling leaked ER-chaperones to the ER during secretion of newly synthesized proteins. Studies have also shown that KDEL receptor may function as a signaling protein that orchestrates membrane flux through the secretory pathway. We have recently shown that KDEL receptor is also a cell surface receptor, which undergoes highly complex itinerary between trans-Golgi network and the plasma membranes via clathrin-mediated transport carriers. Ironically, however, it is still largely unknown how KDEL receptor is distributed to the Golgi at steady state, since its initial discovery in late 1980s. Results We used a proximity-based in vivo tagging strategy to further dissect mechanisms of KDEL receptor trafficking. Our new results reveal that ACBD3 may be a key protein that regulates KDEL receptor trafficking via modulation of Arf1-dependent tubule formation. We demonstrate that ACBD3 directly interact with KDEL receptor and form a functionally distinct protein complex in ArfGAPs-independent manner. Depletion of ACBD3 results in re-localization of KDEL receptor to the ER by inducing accelerated retrograde trafficking of KDEL receptor. Importantly, this is caused by specifically altering KDEL receptor interaction with Protein Kinase A and Arf1/ArfGAP1, eventually leading to increased Arf1-GTP-dependent tubular carrier formation at the Golgi. Conclusions These results suggest that ACBD3 may function as a negative regulator of PKA activity on KDEL receptor, thereby restricting its retrograde trafficking in the absence of KDEL ligand binding. Since ACBD3 was originally identified as PAP7, a PBR/PKA-interacting protein at the Golgi/mitochondria, we propose that Golgi-localization of KDEL receptor is likely to be controlled by its interaction with ACBD3/PKA complex at steady state, providing a novel insight for establishment of cellular homeostasis in the early secretory pathway.

ABSTRACTOver the past century, population growth and climate change have affected most cities in developing countries, being damaged extensively at different scales. For instance, in Iran, the historical sustainable blue-green infrastructure (BGI) is under pressing pressure. However, sustainable BGI could support the environmental, social, and economic sustainability and mitigate as well as adapt to climate change. Qazvin, the historical Persian garden city in the middle of Iran, is a valuable sample of sustainable adaptation to drought and water shortage. Due to the urban development process, population growth, and climate change during the last century, Qazvin has lost a significant part of its historical blue-green infrastructure. This paper aims to assess the effects of population growth and climate change on sustainable BGI in Qazvin and offer appropriate solutions for conserving and rehabilitating sustainable BGI. The research methodology is the case study method. Hence, the principles of environmental, social, and economic sustainability dimensions in the blue-green infrastructure are identified. Data related to population growth, climate change, and urban development in Qazvin are collected, and the effects of these factors on sustainable BGI are analyzed. Finally, the proposed mechanism implementing the sustainable BGI adapted to climate change and urban development has been introduced.

description: Background: Mobile stroke units ( MSU s), equipped with an integrated computed tomography scanner, can shorten time to thrombolytic treatment and may improve outcome in patients with acute ischemic stroke. Original (German) MSU s are staffed by neurologists trained as emergency physicians, but patient assessment and treatment decisions by a remote neurologist may offer an alternative to neurologists aboard MSU. Methods and Results: Remote neurologists examined and assessed emergency patients treated aboard the MSU in Berlin, Germany. Audiovisual quality was rated by the remote neurologist from 1 (excellent) to 6 (insufficient), and duration of video examinations was assessed. We analyzed interrater reliability of diagnoses, scores on the National Institutes of Health Stroke Scale and treatment decisions (intravenous thrombolysis) between the MSU neurologist and the remote neurologist. We included 90 of 103 emergency assessments (13 patients were excluded because of either failed connection, technical problems, clinical worsening during teleconsultation, or missing data in documentation) in this study. The remote neurologist rated audiovisual quality with a median grade for audio quality of 3 (satisfactory) and for video quality of 2 (good). Mean time for completion of teleconsultations was about 19±5 minutes. The interrater reliabilities between the onboard and remote neurologist were high for diagnoses (Cohen's κ=0.86), National Institutes of Health Stroke Scale sum scores (intraclass correlation coefficient, 0.87) and treatment decisions (16 treatment decisions agreed versus 2 disagreed; Cohen's κ=0.93). Conclusions: Remote assessment and treatment decisions of emergency patients are technically feasible with satisfactory audiovisual quality. Agreement on diagnoses, neurological examinations, and treatment decisions between onboard and remote neurologists was high.
Implications of the low frequency turn-over in the spectrum of radio knot C in DG Tau

description: The synchrotron spectrum of radio knot C in the protostellar object DG Tau has a low frequency turn-over. This is used to show that its magnetic field strength is likely to be at least 10 mG, which is roughly two orders of magnitude larger than previously estimated. The earlier, lower value is due to an overestimate of the emission volume together with an omission of the dependence of the minimum magnetic field on the synchrotron spectral index. Since the source is partially resolved, this implies a low volume filling factor for the synchrotron emission. It is argued that the high pressure needed to account for the observations is due to shocks. In addition, cooling of the thermal gas is probably necessary in order to further enhance the magnetic field strength as well as the density of relativistic electrons. It is suggested that the observed spectral index implies that the energy of the radio emitting electrons is below that needed to take part in first order Fermi acceleration. Hence, the radio emission gives insights to the properties of its pre-acceleration phase. Attention is also drawn to the similarities between the properties of radio knot C and the shock induced radio emission in supernovae.

description: Silicon monosulfide is an important silicon bearing molecule detected in circumstellar envelopes and star forming regions. Its formation and destruction routes are not well understood, partially due to the lack of a detailed knowledge on the involved reactions and their rate coefficients. In this work we have calculated and modeled the potential energy surface (PES) of the HSiS system employing highly accurate multireference electronic structure methods. After obtaining an accurate analytic representation of the PES, which includes long-range energy terms in a realistic way via the DMBE method, we have calculated rate coefficients for the Si+SH$\rightarrow$SiS+H reaction over the temperature range of 25-1000K. This reaction is predicted to be fast, with a rate coefficient of $\sim 1\times 10^{-10}\rm cm^3\, s^{-1}$ at 200K, which substantially increases for lower temperatures (the temperature dependence can be described by a modified Arrhenius equation with $α=0.770\times 10^{-10}\rm cm^3\,s^{-1}$, $β=-0.756$ and $γ=9.873\, \rm K$). An astrochemical gas-grain model of a shock region similar to L1157-B1 shows that the inclusion of the Si+SH reaction increases the SiS gas-phase abundance relative to \ce{H2} from $5\times 10^{-10}$ to $1.4\times 10^{-8}$, which perfectly matches the observed abundance of $\sim 2\times 10^{-8}$.

description: A heteronuclear Tb-Al complex (1) was obtained by pyridine-2,6-dicarboxylic acid (H2PDA), AlCl3 and Tb4O7 under hydrothermal condition. Single-crystal X-ray diffraction analysis reveals that 1 is an ion-pair and consists of [Al(H2O)6]3+ cation and [Tb(PDA)3]3- anion; the [Al(H2O)6]3+ cations and [Tb(PDA)3]3- anions are further connected by hydrogen bonds to construct a 3D NaCl-like topology. Lattice water molecules in 1 fabricate a cubic (H2O)8-octamer by hydrogen bonds, which is located in the void of 1. Luminescent property indicates efficient energy transfer from PDA3- ligand to Tb3+ in 1, exhibiting the typical green emission of Tb3+ in the visible region.

description: The coordinate transformation between emission coordinates and inertial coordinates in Minkowski space-time is obtained for arbitrary configurations of the emitters. It appears that a positioning system always generates two different coordinate domains, namely, the front and the back emission coordinate domains. For both domains, the corresponding covariant expression of the transformation is explicitly given in terms of the emitter world-lines. This task requires the notion of orientation of an emitter configuration. The orientation is shown to be computable from the emission coordinates for the users of a `central' region of the front emission coordinate domain. Other space-time regions associated with the emission coordinates are also outlined.
