description: Silicon-based tracking detectors have been used in several important applications, such as in cancer therapy using particle beams, and for the discovery of new elementary particles at the Large Hadron Collider at CERN. III-V semiconductor materials are an attractive alternative to silicon for this application, as they have some superior physical properties. They could meet the demands for fast timing detectors allowing time-of-flight measurements with ps resolution while being radiation tolerant and cost-efficient. As a material with a larger density, higher atomic number Z and much higher electron mobility than silicon, GaAs exhibits faster signal collection and a larger signal per μm of sensor thickness. In this work, we report on the fabrication of n-in-n GaAs thin-film devices intended to serve next-generation high-energy particle tracking detectors. Molecular beam epitaxy (MBE) was used to grow high-quality GaAs films with doping levels sufficiently low to achieve full depletion for detectors with an active thickness of 10 μm. The signal collection speed of the detector structures was assessed using the transient current technique (TCT). To elucidate the structural properties of the detector, Kelvin probe force microscopy (KPFM) was used, which confirmed the formation of the junction in the detector and revealed residual doping in the intrinsic layer. Our results suggest that GaAs thin films are suitable candidates to achieve thin and radiation-tolerant tracking detectors.

description: The extension of the serverless paradigm to the edge-cloud continuum is a groundbreaking advancement in the field of distributed computing. While serverless architectures abstracts the infrastructure management and enable function as a service with operational efficiency, edge computing brings processing closer to the data source reducing latency and improving real time capabilities. As such, EDGELESS presents a strong case for academic, industrial and commercial adoption as well as introducing new application development scenarios and fine-grained resource utilisation. In this deliverable we provide an insight on the exploitation strategy for the project based on the market context, business challenges and value proposition of EDGELESS. The report also presents the methodology and activities performed to arrive at the exploitation plans. Starting with an overview of the overall exploitation strategy for the project’s results, the deliverable provides an insight into the planned utilisation and propagation of the outcomes across identified segments. For a meaningful exploitation strategy, it is important to identify key stakeholders, business values and related value proposition. To fulfil that, a set of key customer roles were identified as stakeholders for the results and their respective profiles were developed based on questionnaires and interviews. Additionally, a SWOT analysis was performed to extend the value proposition of the results based on market drivers, needs, trends and use cases.A detailed section on joint and individual exploitation plans complements this by providing insights into the impact of the results within the ecosystem and the individual as well as overall summary of currently envisaged key exploitable results. The final section on IPR management tackles the current and planned approaches regarding intellectual property and licensing of the results.In summary, the deliverable presents the exploitation strategy to utilise the EDGELESS platform and learnings from the development process, to foster innovation and a paradigm shift in serverless in the edge-cloud continuum for industries and academia.

description: © 2015 Optical Society of America. We study the problem of constructing an optical surface separating two homogeneous, isotropic media, one of which has a negative refractive index. In doing so, we develop a vector form of Snell's law, which is used to study surfaces possessing a certain uniform refraction property, in both the near- and far-field cases. In the near-field problem, unlike the case when both materials have positive refractive indices, we show that the resulting surfaces can be neither convex nor concave.

description: Eine sinnvolle Sanierung historischer Bausubstanz setzt die Überprüfung von Gründungskörper und Baugrund voraus, insbesondere wenn Umnutzungen vorgesehen sind. Die Vielfalt der Gründungsmethoden und _materialien historischer Bauwerke einerseits und der erforderliche schonende Umgang mit historischer Bausubstanz andererseits erfordern neue Untersuchungsmethoden. Bei Tragfähigkeitsuntersuchungen müssen die langzeitlich erfolgten Veränderungen von Baugrund und Bauwerk berücksichtigt werden. Dementsprechend werden zuerst die Besonderheiten historischer Gründungskörper umrissen. Danach werden häufig auftretende baugrundbedingte Gründungsschäden und moderne Untersuchungsmethoden beschrieben. An mehreren konkreten Objekten werden Gründungsschäden als Folge langzeitlich wirkender geologischer Prozesse erläutert.
description: It is not possible to carry out effective restoration of historical buildings, particulary when they are going to be put to new use, without first investigating of methods of constructing foundations and the many the foundations and the underlying geology. The variety different materials used, as well as the necessity to treat historical buildings with the utmost care, require new methods of investigation. Assessments of bearing capacity must take into account the long-term changes that have taken place in the foundation conditions and the buildings themselves over the past centuries. The characteristic features of historical foundations are first described. The most common types of foundation damage caused by subsurface changes are then dealt with, and modern methods of investigation are explained. Foundation damage as a result of long-term geological processes is illustrated by means of several actual examples.

description: On 27 October, 2003, two GOES M-class flares occurred in the lapse of three hours in active region NOAA 10486. The two flares were confined and their associated brightenings appeared at the same location, displaying a very similar shape both at the chromospheric and coronal levels. We focus on the analysis of magnetic field (SOHO/MDI), chromospheric (HASTA, Kanzelhoehe Solar Observatory, TRACE) and coronal (TRACE) observations. By combining our data analysis with a model of the coronal magnetic field, we compute the magnetic field topology associated to the two M flares. We find that both events can be explained in terms of a localized magnetic reconnection process occurring at a coronal magnetic null point. This null point is also present at the same location one day later, on 28 October, 2003. Magnetic energy release at this null point was proposed as the origin of a localized event that occurred independently with a large X17 flare on 28 October, 2003, at 11:01 UT. The three events, those on 27 October and the one on 28 October, are homologous. Our results show that coronal null points can be stable topological structures where energy release via magnetic reconnection can happen, as proposed by classical magnetic reconnection models.

description: The bound state problem of $D^0\bar{D}^{\ast0}$ ($\bar{D}^0{D}^{\ast0}$) is relevant to the molecular interpretation of the X(3872). We investigated this problem in a chiral quark model by solving the resonating group method equation. We found the system is unbound through S-wave $π$ and $σ$ interactions. The inclusion of $ρ$ and $ω$ meson exchanges is helpful to the formation of a molecule. Because the binding energy relies on the coupling constants, we cannot draw a definite conclusion whether a molecular state exists in $D^0\bar{D}^{\ast0}$ ($\bar{D}^0{D}^{\ast0}$) system. When moving on to the bottom counterpart, we obtained an S-wave $B\bar{B}^\ast$ state.

description: © 2015 American Physical Society. © 2015 American Physical Society. We present a search for ten baryon number violating decay modes of Λ hyperons using the CLAS detector at Jefferson Laboratory. Nine of these decay modes result in a single meson and single lepton in the final state (Λ→m) and conserve either the sum or the difference of baryon and lepton number (B±L). The tenth decay mode (Λ→p¯π+) represents a difference in baryon number of two units and no difference in lepton number. We observe no significant signal and set upper limits on the branching fractions of these reactions in the range (4-200)×10-7 at the 90% confidence level.

description: We have revisited the problem of metallicity prediction of RR Lyrae stars from their near-infrared light curves in the Cousins I waveband. Our study is based on high-quality time-series photometry and state-of-the-art high-resolution spectroscopic abundance measurements of 80 fundamental-mode (RRab) and 24 first-overtone (RRc) stars, spanning $\sim$[$-2.7$,$+0.18$] dex and $\sim$[$-3$,$-0.5$] dex ranges, respectively. Employing machine-learning methods, we investigated various light-curve representations and regression models to identify their optimal form for our objective. Accurate new empirical relations between the [Fe/H] iron abundance and the light-curve parameters have been obtained using Bayesian regression for both RRab and RRc stars with mean absolute prediction errors of 0.16 and 0.18 dex, respectively. We found that earlier $I$-band [Fe/H] estimates had a systematic positive bias of up to $\sim 0.4$ dex in the metal-poor regime. Our new predictive models were deployed on large ensembles of RR Lyrae stars to obtain photometric metallicity distribution functions (MDFs) for various old stellar populations in and around the Milky Way. We find that the mode of the old bulge component's MDF is approximately $-1.4$ dex, in remarkable agreement with the latest spectroscopic result. Furthermore, we derive MDF modes of $-1.83$, $-2.13$, and $-1.77$ dex for the Large and Small Magellanic Clouds, and the Sagittarius dwarf galaxy, respectively.

description: Intensive Subrosionsvorgänge im Zusammenhang mit dem Flutungsprozeß in der Mansfelder Mulde führten Mitte der 70er Jahre in Teilen der Stadt Eisleben zu starken, oft bruchartigen Oberflächendeformationen mit umfangreichen Bauschäden. Nach einer Phase relativer Ruhe traten 1995 erneut Senkungsbewegungen auf, die zum Bruch einer Hauptversorgungsleitung der MIDEWA führten. Die Leitung, die den gesamten Südraum Sachsen-Anhalt mit Fernwasser versorgt, mußte daraufhin völlig neu geplantwerden. In diesem Zusammenhang war eine Senkungs- und Deformationsprognose gefordert. Sie mußte wegen fehlender Senkungsmeßergebnisse auf Vergangenheitsdaten aufbauen. Dies entspricht einer worst-case- Betrachtung, so daß die prognostizierten Deformationsparameter auf der sicheren Seite liegen. Daraufhin vorgeschlagene und realisierte technische Sicherungsmaßnahmen garantieren eine Betriebssicherheit der Leitung über viele Jahrzehnte.
description: In the mid-1970s, strong underground solution (subrosion) associated with flooding took place in the Mansfeld syncline and caused considerable subsidence and often fracture-like surface deformation with serious damage to buildings in certain areas of the town of Eisleben. After a relatively quiet period, subsidence reoccurred in 1995 damaging one of MIDEWA’s main water pipelines. As a consequence, the pipeline, which supplies water to the whole southern area of Saxony-Anhalt, had to be completely re-designed. In this context, future subsidence and deformation had to be predicted. Due to the lack of subsidence measurements, the prediction had to rely on historical data. With this worst-case assumption, the predicted deformation parameters are on the safe side. Technical safeguards proposed and installed on this basis will guarantee operational reliability of the pipeline for many decades

description: We present a detailed derivation of a model to study effects of self-gravitation from semi-classical gravity, described by the Schrödinger-Newton equation, employing spin superposition states in inhomogeneous magnetic fields, as proposed recently for experiments searching for gravity induced entanglement. Approximations for the experimentally relevant limits are discussed. Results suggest that spin interferometry could provide a more accessible route towards an experimental test of quantum aspects of gravity than both previous proposals to test semi-classical gravity and the observation of gravitational spin entanglement.

description: As part of the DarkSide program of direct dark matter searches using two-phase argon TPCs, a prototype detector with an active volume containing 10 kg of liquid argon, DarkSide-10, was built and operated underground in the Gran Sasso National Laboratory in Italy. A critically important parameter for such devices is the scintillation light yield, as photon statistics limits the rejection of electron-recoil backgrounds by pulse shape discrimination. We have measured the light yield of DarkSide-10 using the readily-identifiable full-absorption peaks from gamma ray sources combined with single-photoelectron calibrations using low-occupancy laser pulses. For gamma lines of energies in the range 122-1275 keV, we get light yields averaging 8.887±0.003(stat) ±0.444(sys) p.e./keVee. With additional purification, the light yield measured at 511 keV increased to 9.142±0.006(stat) p.e./keVee.

The magnetic field $B$ is assumed strong. The energy spectrum of collective excitations, the sound spectrum as well as the effective magnetic mass of magnetoexcitons are presented in the strong magnetic field regime. The superfluid density $n_S$ and the temperature of the Kosterlitz-Thouless phase transition $T_c$ are shown to be increasing functions of the excitonic density $n$ but decreasing functions of $B$ and the interlayer separation $D$. Numerical results are presented from these calculations.

Two coupled equations describing the interaction between a high-frequency CPEM wave and the low-frequency electrostatic wake field are derived. It is found that the generation of the wake fields depends on the presence of the ion species. The wake field generation in turn leads to de-acceleration and frequency down conversion of the electromagnetic pulse.

description: One of the problems for the cyclic Universe will be its compatibility with a vast population of indestructible black holes that accumulate from cycle to cycle. The article considers a simple iterative model of the evolution of black holes in a cyclic Universe, independent of specific cosmological theories. The model has two free parameters that determine the iterative decrease in the number of black holes and the increase in their individual mass. It is shown that this model, with wide variations in the parameters, explains the observed number of supermassive black holes at the centers of galaxies, as well as the relationships between different classes of black holes. The mechanism of accumulation of relict black holes during repeated pulsations of the Universe may be responsible for the black hole population detected by LIGO observations and probably responsible for the dark matter phenomenon. The number of black holes of intermediate masses corresponds to the number of globular clusters and dwarf satellite galaxies. These results argue for models of the oscillating Universe, and at the same time impose substantial requirements on them. Models of a pulsating Universe should be characterized by a high level of relict gravitational radiation generated at the time of maximum compression of the Universe and mass mergers of black holes, as well as solve the problem of the existence of the largest black hole that is formed during this merger. It has been hypothesized that some neutron stars can survive from past cycles of the Universe and contribute to dark matter. These relict neutron stars will have a set of features by which they can be distinguished from neutron stars born in the current cycle of the birth of the Universe. The observational signs of relict neutron stars and the possibility of their search in different wavelength ranges are discussed.

description: We present measurements of three-dimensional correlation functions of like-sign, low-transverse-momentum kaon pairs from √sNN=200 GeV Au+Au collisions. A Cartesian surface-spherical harmonic decomposition technique was used to extract the kaon source function. The latter was found to have a three-dimensional Gaussian shape and can be adequately reproduced by Therminator event-generator simulations with resonance contributions taken into account. Compared to the pion one, the kaon source function is generally narrower and does not have the long tail along the pair transverse momentum direction. The kaon Gaussian radii display a monotonic decrease with increasing transverse mass mT over the interval of 0.55≤mT≤1.15 GeV/c2. While the kaon radii are adequately described by the mT -scaling in the outward and sideward directions, in the longitudinal direction the lowest mT value exceeds the expectations from a pure hydrodynamical model prediction. © 2013 American Physical Society.

We consider which finite groups G have the property that every faithful action of G on a connected smooth projective curve over k lifts to characteristic zero. Oort conjectured that cyclic groups have this property. We show that if a cyclic-by-p group G has this property, then G must be either cyclic or dihedral, with the exception of A_4 in characteristic 2. This proves one direction of a strong form of the Oort Conjecture.

description: The text is a review of Titian. Love, Desire, Death (London, The National Gallery, 16 March 2020 - 17 January 2021), an exhibition of six 'poems' created by the Venetian painter for the young Philip of Habsburg, future king of Spain. The canvases on view are mostly based on Ovid's Metamorphoses and represent mythological subjects; they are 'poesie' (figurative poems) whose protagonists are predominantly women - Diana, Venus, Andromeda, Danaë, Callisto, Europa and the nymphs. The understanding of the paintings is never univocal, never simplistic: they represent Titian at his best, the most complex creation of a mature painter who, at sixty years old, knows his patron, and his patron's passion for women and hunting, well.

description: We have recently shown that for the special case of a bipartite system with binary inputs and outputs there exist equalities in local theories which are violated by quantum theory. The amount of white noise tolerated by these equalities are twice that of inequalities. In this paper we will first introduce an inequality in bipartite qutrits systems which, if non-maximally entangled state is used instead of maximally entangled state, is violated more strongly by quantum theory. Hence reproducing the results obtained in the literature. We will then prove that our equalities in this case are violated by quantum theory too, and they tolerate much more white noise than inequalities.

description: Purpose: This study examined the relationship between utterance length, syntactic complexity, and the probability of making an error at the utterance level.Method: The participants in this study included 830 Spanish-speaking first graders who were learning English at school. Story retells in both Spanish and English were collected from all children. Generalized mixed linear models were used to examine within-child and between-children effects of utterance length and subordination on the probability of making an error at the utterance level.Results: The relationship between utterance length and grammaticality was found to differ by error type (omission vs. commission), language (Spanish vs. English), and level of analysis (within-child vs. between-children). For errors of commission, the probability of making an error increased as a child produced utterances that were longer relative to their average utterance length (within-child effect). Contrastively, for errors of omission, the probability of making an error decreased when a child produced utterances that were longer relative to their average utterance length (within-child effect). In English, a child who produced utterances that were, on average, longer than the average utterance length for all children produced more errors of commission and fewer errors of omission (between-children effect). This between-children effect was similar in Spanish for errors of commission but nonsignificant for errors of omission. For both error types, the within-child effects of utterance length were moderated by the use of subordination.Conclusion: The relationship between utterance length and grammaticality is complex and varies by error type, language, and whether the frame of reference is the child’s own language (within-child effect) or the language of other children (between-children effect).

Normal ordered exponential approach to thermal properties and time-correlation functions: General theory and simple examples

description: A normal ordered exponential parametrization is used to obtain equations for thermal one-and two-particle reduced density matrices, as well as free energies, partition functions and entropy for both Fermionic (electronic) and Bosonic (vibrational) Hamiltonians. A first principles derivation of the equations, relying only on a simple Wick's theorem and starting from the differential equation $\frac{d \hat{D}}{d β}= - (\hat{H}-μ\hat{N})\hat{D}$, is presented that yields a differential equation for the amplitudes representing density cumulants, as well as the grand potential. In contrast to other approaches reported in the literature the theory does not use perturbation theory in the interaction picture and an integral formulation as a starting point, but rather requires a propagation of the resulting differential equation for the amplitudes. While the theory is applicable to general classes of many-body problems in principle, here, the theory is illustrated using simple model systems. For one-body Fermionic Hamiltonians, Fermi-Dirac one-body reduced density matrices are recovered for the grand-canonical formulation. For multidimensional harmonic oscillators numerically exact results are obtained using the thermal normal ordered exponential (TNOE) approach. As an application of the related time-dependent formulation numerically exact time-autocorrelation functions and absorption spectra are obtained for harmonic Franck Condon problems. These examples illustrate the basic soundness of the scheme and are used for pedagogical purposes. Other approaches in the literature are only discussed briefly and no detailed comparative discussion is attempted.

description: Erhebungen zeigen, daß Kanalnetze z.T. starke bauliche Mängel aufweisen und daß durch Undichtigkeiten Grundwasser- und Bodenkontaminationen zu befürchten sind. Die Auswertung von Forschungs- und Entwicklungsarbeiten zur Detektion und Quantifizierung von Abwasserexfiltrationen aus undichten Kanälen durch hydrogeologisch-hydrogeochemische, hydraulische und geophysikalische Methoden ermöglicht eine zusammenfassende Bewertung im Hinblick auf Anwendung und Aussage der jeweiligen Verfahren. Ergebnisse aus hydrochemischen und geochemischen Untersuchungen zur Exfiltration von überwiegend häuslichem Schmutzwasser werden dargestellt. Als Randbedingungen sind unterschiedlichste Schadensarten und -klassen in Sohl-, Kämpfer- und Scheitellagen des Rohrquerschnitts sowie die Untergrundverhältnisse, die schwer bis gut durchlässige Sedimente bei Grundwasserständen < 50 cm bis 500 cm unterhalb der Rohrsohle umfassen, berücksichtigt. Anhand von Leitparametern wurden Abwasserinhaltsstoffe in der unmittelbaren Umgebung, insbesondere von schweren Schäden nachgewiesen. Sie sind auf eine nur wenige dm müächtige Infiltrationsschicht beschränkt, im Grundwasser jedoch nicht belegt.Umweltrelevante Stoffbelastungen schränken die multifunktionelle Nutzungsmöglichkeit von Aushubmassen bei Kanalbaumaßnahmen ein.
description: Surveys have shown that sewer systems are quite often damaged, causing a pollution hazard for soil and groundwater. Hydrogeological, hydrogeochemical, hydraulic and geophysical methods for the detection and quantification of leaked sewage have been compared. The main results of the project are illustrated using case studies on liquids leaked from sewers carrying mainly domestic waste water and exhibiting different types and categories of damage at he bottom, sides and top of the pipe. The condition of the underlying soil was characterized, i.e. sediments of variable permeability, ranging from good to poor, with groundwater levels of less than 50 cm to as much as 500 cm below of the pipe bottom. Using indicator parameters, waste waterconstituents were detected in the immediate vicinity of categories 0, 1 and 2 damage. Infiltration is limited to a zone only a few tens of centimetres thick, so that the occurrence of environmentally relevant concentrations is assumed to be mainly confined to the damage categories mentioned. Nevertheless, such contamination limits the possible uses of soil excavated during sewer reconstruction

description: We have measured and analyzed the hyperfine structure of two lines, one at 583 nm and one at 401 nm, of the only stable fermionic isotope of atomic erbium as well as determined its isotope shift relative to the four most-abundant bosonic isotopes. Our work focuses on the J→J+1 laser cooling transitions from the [Xe]4f126s2(3H6) ground state to two levels of the excited [Xe]4f126s6p configuration, which are of major interest for experiments on quantum degenerate dipolar Fermi gases. From a fit to the observed spectra of the strong optical transition at 401 nm we find that the magnetic dipole and electric quadrupole hyperfine constants for the excited state are Ae/h=-100.1(3)MHz and Be/h=-3079(30)MHz, respectively. The hyperfine spectrum of the narrow transition at 583 nm, was previously observed and accurate Ae and Be coefficients are available. A simulated spectrum based on these coefficients agrees well with our measurements. We have also determined the hyperfine constants using relativistic configuration-interaction ab initio calculations. The agreement between the ab initio and fitted data for the ground state is better than 0.1%, while for the two excited states the agreement is 1% and 11% for the A e and Be constants, respectively. © 2013 American Physical Society.

description: We predict atomic, electronic, and magnetic structures of a hypothetical compound LaOFeSb by first-principles density-functional calculations. It is shown that LaOFeSb prefers a stripe-type antiferromagnetic phase (i.e., spin density wave (SDW) phase) to the non-magnetic (NM) phase, with a larger Fe spin moment and greater SDW-NM energy difference than those of LaOFeAs. The SDW phase is found to favor the orthorhombic structure while the tetragonal structure is more stable in the NM phase. In the NM-phase LaOFeSb, the electronic bandwidth near the Fermi energy is reduced compared with LaOFeAs, indicating smaller orbital overlap between Fe $d$ states and subsequently enhanced intra-atomic exchange coupling. The calculated Fermi surface in the NM phase consists of three hole and two electron sheets, and shows increased nesting between two hole and two electron sheets compared with LaOFeAs. Monotonous changes found in our calculated material properties of LaOFePn (Pn=P, As, and Sb), along with reported superconducting properties of doped LaOFeP and LaOFeAs, suggest that doped LaOFeSb may have a higher superconducting transition temperature.

CONGENITAL CLUBFOOT IN CHILDREN: PSYCHOEMOTIONAL STATUS AND TREATMENT METHODS
Creators: name: Narziqulov, U.K.
Publisher: name: Zenodo
Year: 2025

description: In children with congenital clubfoot, not only the movements of the ankle joint but also the entire musculoskeletal system’s functions are impaired, which can lead to deformities in posture. Therefore, early treatment is crucial to prevent secondary complications of the disease. If the disease persists for a long period, it affects the child’s walking ability, creating discomfort in movements, which in turn negatively impacts their psychoemotional state.

description: Momentum imaging measurements from two experiments are presented and interpreted with the aid of ab initio theoretical calculations to describe the dissociative electron attachment (DEA) dynamics of CO2. The dynamics of the transient negative ions of CO2- involve several conical intersections taking part in mechanisms that have only recently been understood. We address the problem of how the 4-eV 2Πu shape resonance in CO2 proceeds to dissociate to CO(1Σ+) + O-(2P) by DEA. © 2013 American Physical Society.

description: Prior work on diagnosing Alzheimer's disease from magnetic resonance images of the brain established that convolutional neural networks (CNNs) can leverage the high-dimensional image information for classifying patients. However, little research focused on how these models can utilize the usually low-dimensional tabular information, such as patient demographics or laboratory measurements. We introduce the Dynamic Affine Feature Map Transform (DAFT), a general-purpose module for CNNs that dynamically rescales and shifts the feature maps of a convolutional layer, conditional on a patient's tabular clinical information. We show that DAFT is highly effective in combining 3D image and tabular information for diagnosis and time-to-dementia prediction, where it outperforms competing CNNs with a mean balanced accuracy of 0.622 and mean c-index of 0.748, respectively. Our extensive ablation study provides valuable insights into the architectural properties of DAFT. Our implementation is available at https://github.com/ai-med/DAFT.

description: We introduce a new observable, 'gluino stransverse mass', which is an application of the Cambridge $m_{T2}$ variable to the process where gluinos are pair produced in proton-proton collision and each gluino subsequently decays into two quarks and one LSP, $i.e. \tilde{g}\tilde{g} \to qq\tildeχ_1^0\ qq\tildeχ_1^0$. We show that the gluino stransverse mass can be utilized to measure the gluino and the lightest neutralino masses separately, and also the (1st and 2nd generation) squark masses if lighter than the gluino mass, thereby providing a good first look at the pattern of sparticle masses experimentally.

description: Relativistic jets can interact with the ambient gas distribution of the host galaxy, before breaking out to larger scales. In the past decade several studies have simulated jet-driven outflows to understand how they affect the nearby environment, and over what spatial and temporal scales such interactions occur. The simulations are able to capture the interaction of the jets with the turbulent clumpy interstellar medium and the resultant energetics of the gas. In this review we summarise the results of such recent studies and discuss their implications on the evolution of the dynamics of the gas distribution and the star formation rate.

Approximate Functionals in Hypercomplex Kohn-Sham Theory

description: The recently developed hypercomplex Kohn-Sham (HCKS) theory shows great potential to overcome the static/strong correlation issue in density functional theory (DFT), which highlights the necessity of further exploration of the HCKS theory toward better handling many-electron problem. This work mainly focuses on approximate functionals in HCKS, seeking to gain more insights into functional development from the comparison between Kohn-Sham (KS) DFT and HCKS. Unlike KS-DFT, HCKS can handle different correlation effects by resorting to a set of auxiliary orbitals with dynamically varying fractional occupations. These orbitals of hierarchical correlation (HCOs) thus contain distinct electronic information for better considering the exchange-correlation effect in HCKS. The test on the triplet-singlet gaps shows that HCKS has much better performance as compared to KS-DFT in use of the same functionals, and the systematic errors of semi-local functionals can be effectively reduced by including appropriate amount of the HCO-dependent Hartree-Fock (HF) exchange. In contrast, KS-DFT shows large systematic errors, which are hardly reduced by the functionals tested in this work. Therefore, HCKS creates new channels to address to the strong correlation issue, and further development of functionals that depend on HCOs and their occupations is necessary for the treatment of strongly correlated systems.

description: The flow of genetic information is regulated by selective nucleocytoplasmic transport of messenger RNA:protein complexes (mRNPs) through the nuclear pore complexes (NPCs) of eukaryotic cells. However, the three-dimensional (3D) pathway taken by mRNPs as they transit through the NPC, and the kinetics and selectivity of transport, remain obscure. Here we employ single-molecule fluorescence microscopy with an unprecedented spatiotemporal accuracy of 8 nm and 2 ms to provide new insights into the mechanism of nuclear mRNP export in live human cells. We find that mRNPs exiting the nucleus are decelerated and selected at the centre of the NPC, and adopt a fast-slow-fast diffusion pattern during their brief, ∼12 ms, interaction with the NPC. A 3D reconstruction of the export route indicates that mRNPs primarily interact with the periphery on the nucleoplasmic side and in the centre of the NPC, without entering the central axial conduit utilized for passive diffusion of small molecules, and eventually dissociate on the cytoplasmic side. © 2013 Macmillan Publishers Limited.
