description: Substance use disorder (SUD) is difficult to treat, as evidenced by its high prevalence and relapse rates. Research shows, however, that hope may have the potential to create effective and efficient change in the way we prevent and treat SUD. In order to utilize hope in this way, we must have a good understanding of what hope is. This phenomenological study aims to explore and describe the essence of hope through the lived experience of individuals in recovery from a SUD. Through interviews with 20 informants to generate data and an iterative interpretative process to identify shared meanings, hope emerged as an experience that is lived, spiritual, relational, revivifying, and felt. These results point to a need for more research regarding a theory of hope, improved scales for accurately measuring hope, and new language for talking about hope when using it as a tool in recovery and elsewhere.

description: Tylosin A is a macrolide antibiotic used in beekeeping. The aim of the study was to characterise the behaviour of tylosin A in honey after heating and during storage, and to identify its degradation products using a non-targeted approach. In addition, the possibility of a semi-quantification of tylosin B using tylosin A was assessed as a case study for the semi-quantification of degradation products using the parent compounds. The results showed significant degradation of tylosin A in aqueous solution (~96%) as well as in spiked and incurred honey dissolved in water (~50% and ~29%, respectively) after heating at 100°C for 90 min. However, at a lower heating temperature of 70°C, degradation was only observed in water (~31%). When stored at room temperature (27°C) for one year, tylosin A degraded significantly (~47%) in an incurred honey sample. Tylosin B, the only reported degradation product of tylosin A in honey so far, increased significantly in aqueous solution under all treatments, but it only increased in spiked water-honey mixture after heating at 100°C. Two new degradation products, namely 5-O-mycaminosyltylonolide (OMT) and lactenocin, were tentatively identified in water and spiked honey after heating at 100°C. The results of the present study reinforce the conclusion that relying only on the water model or spiked food matrix is not sufficient to understand the thermal degradation of antibiotics in food matrices. Finally, a semi-quantification of tylosin B with a relative error of 20% in an incurred honey sample was possible using the response factor of tylosin A, its parent compound. The results of this study prove that a semi-quantification using the parent compound to quantify its degradation compound can provide satisfactory results, but this will be analyte-dependent.

description: We present a coherent state quantization of the dynamics of a relativistic test particle on a one-sheet hyperboloid embedded in a three-dimensional Minkowski space. The group SO_0(1,2) is considered to be the symmetry group of the system. Our procedure relies on the choice of coherent states of the motion on a circle. The coherent state realization of the principal series representation of SO_0(1,2) seems to be a new result.

description: In this note we use the Matsuo–Cherednik duality between the solutions to the Knizhnik–Zamolodchikov (KZ) equations and eigenfunctions of Calogero–Moser Hamiltonians to get the polynomial p8-truncation of the Calogero–Moser eigenfunctions at a rational coupling constant. The truncation procedure uses the integral representation for the hypergeometric solutions to KZ equations. The s→∞ limit to the pure p-adic case has been analyzed in the n=2 case.

description: Filaments of cold gas ($T\leq 10^{4}$ K) are found in the inner regions of many cool-core clusters. These structures are thought to play a major role in the regulation of feedback from active galactic nuclei (AGN). We study the morphology of the filaments, their formation, and their impact on the propagation of the outflowing AGN jets. We present a set of GPU-accelerated 3D (magneto)hydrodynamical simulations of an idealized Perseus-like cluster using the performance portable code AthenaPK. We include radiative cooling, and a self-regulated AGN feedback model that redistributes accreted material through kinetic, thermal and magnetic feedback. We confirm that magnetic fields play an important role in both the formation and evolution of the cold material. These suppress the formation of massive cold discs and favour magnetically supported filaments over clumpy structures. Achieving resolutions of $25-50$ pc, we find that filaments are not monolithic as they contain numerous and complex magnetically supported sub-structures. We find that the mass distribution of these clumps follows a $\mathrm{d}N/\mathrm{d}M \propto M^{-1.6}$ power-law for all investigated filaments. Studying the evolution of individual filaments, we find that their formation pathways can be diverse. We find examples of filaments forming through a combination of gas uplifting and condensation, as well as systems of purely infalling clumps condensing out of the intracluster medium. The density contrast between the cold gas and the outflowing hot material leads to recurring deflections of the jets, favouring inflation of bubbles.

description: Löss-Paläoboden Sequenzen sind wichtige terrestrische Archive für die Rekonstruktion der quartären Landschafts- und Klimageschichte. Die Entwicklung neuer, quantitativerer Paläoklima-Proxies könnte in den kommenden Jahren eine neue Ära in der Lössforschung einleiten. Dieser Review-Artikel stellt die Prinzipien, die zugrunde liegende Analytik, und erste Anwendungsbeispiele für einige dieser Proxies vor, welche derzeit entwickelt werden. Wir diskutieren das Potential von (i) pflanzenwachsbürtigen n-Alkanen als Biomarker für die Rekonstruktion der Vegetationsgeschichte, (ii) Aminosäure Razemisierung und Glycerin-Dialkyl-Glycerin-Tetraether (GDGT) Indizes als Proxies für die Rekonstruktion der Paläotemperatur und (iii) substanzspezifischen δD and δ18O Analysen an pflanzenbürtigen n-Alkanen bzw. Zuckern für die Entwicklung von Proxies zur Rekonstruktion von Paläoklima/-aridität. Während wir versuchen, die Leserschaft für die methodischen und analytischen Neuentwicklungen und deren Potential für die Lössforschung zu begeistern, verweisen wir gleichzeitig auch auf die Limitierungen und Schwächen der jeweiligen Methoden. So müssen beispielsweise Degradationseffekte oder postsedimentäre ‚Kontamination’ bei der Interpretation von Biomarker-Rekords berücksichtigt und weiter untersucht werden. Des Weiteren könnte sich die Quantifizierung der unterschiedlichen Einflussfaktoren auf Deuterium- und 18O-Rekords als herausfordernd erweisen.

description: This special issue on automotive Cyber-Physical Systems(CPS) safety and security is a continuation
of the special issue that appeared in ACM Transactions on Cyber-Physical Systems, Vol. 7,
No. 1, in January 2023. It features a second set of seven articles, spanning across a variety of topics,
such as electric and autonomous vehicles, automotive control, and in-vehicle networks, again
with a focus on safety and security. To give an impression on how rich the research literature on
this domain is, we provided a brief survey in Part 1 of this special issue. In Part 2, we continue
that survey—once again, our goal is not to exhaustively list all of the problems that have been
addressed in this area but to provide a larger context for the seven articles featured here.

description: Den Schwerpunkt dieser Arbeit bilden die Ergebnisse sedimentologischer, palynologischer, malakologischer und chronometrischer Untersuchungen an Sedimenten aus dem Zentralbereich des Paläoseebeckens Neumark-Nord 2. Die interdisziplinären Untersuchungen an dem 11 m mächtigen Hauptprofil A und benachbarten Profilen zeigen übereinstimmend, dass die limnische Sedimentation vom Ende des Saale-Komplexes über die Eem-Warmzeit bis in die Weichsel-Kaltzeit erfolgte. Das Profil lässt Seespiegelschwankungen mit einer generellen Tendenz der Verflachung und Verlandung sowie wechselnde Sedimentationsraten erkennen. Durch die palynologischen Untersuchungen sind außerdem mit Erosion und Sedimentumlagerungen verbundene Hiaten festgestellt worden. Eine von Laurat et al. (2006) und Mania et al. (2008, 2010) im Profil ausgewiesene zusätzliche Warmzeit, die durch eine Kaltphase von der Eem-Warmzeit separiert und zudem jünger als das Interglazial von NN1 sein soll, existiert nicht. Vor allem die palynostratigraphische, aber auch die malakologische Koinzidenz der Becken NN1 und NN2 belegt die Gleichaltrigkeit der Ablagerungen. Somit ist in Neumark-Nord zwischen der Saale-Grundmoräne der Zeitz-Phase und den periglaziären Bildungen der Weichsel-Kaltzeit nur eine Warmzeit nachweisbar, das Eem. Dies wird durch neue geochronologische Daten eindeutig verifiziert. Daher können die zuletzt von Mania et al. (2010) dokumentierten Lagerungsbeziehungen, nach denen die Beckenfolge von NN2 über der von NN1 liegen soll, nicht bestätigt werden. In Neumark-Nord werden die klimatischen Besonderheiten des Mitteldeutschen Trockengebietes während der Eem-Warmzeit deutlich. Insofern bietet der Vergleich der Eem-Vorkommen von Neumark-Nord, Gröbern und Grabschütz ein Lehrbeispiel für die standortspezifische Variabilität benachbarter synchroner Warmzeitprofile.

description: We study the nanoscale phase coexistence of ferromagnetic metallic (FMM) and antiferromagnetic insulating (AFI) regions by including the effect of AF superexchange and weak disorder in the double exchange model. We use a new Monte Carlo technique, mapping on the disordered spin-fermion problem to an effective short range spin model, with self-consistently computed exchange constants. We recover `cluster coexistence' as seen earlier in exact simulation of small systems. The much larger sizes, $\sim 32 \times 32$, accessible with our technique, allows us to study the cluster distribution for varying electron density, disorder, and temperature. We track the magnetic structure, obtain the density of states, with its `pseudogap' features, and, for the first time, provide a fully microscopic estimate of the resistivity in a phase coexistence regime, comparing it with the `percolation' scenario.

On the complexity of analyticity in semi-definite optimization
Creators: name: Mohammad-Nezhad, Ali
name: Basu, Saugata
Publisher: name: Elsevier
Year: 2024

description: It is well-known that the central path of semi-definite optimization, unlike linear optimization, has no analytic extension to μ = 0 in the absence of the strict complementarity condition. In this paper, we consider a reparametrization μ ↦ μ ρ , with ρ being a positive integer, that recovers the analyticity of the central path at μ = 0 . We investigate the complexity of computing ρ using algorithmic real algebraic geometry and the theory of complex algebraic curves. We prove that the optimal ρ is bounded by 2 O ( m 2 + n 2 m + n 4 ) , where n is the matrix size and m is the number of affine constraints. Our approach leads to a symbolic algorithm, based on the Newton-Puiseux algorithm, which computes a feasible ρ using 2 O ( m + n 2 ) arithmetic operations.

description: We use multi-band optical and near-infrared photometric observations of galaxies in the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS) to predict photometric redshifts using artificial neural networks. The multi-band observations span over 0.39 microns to 8.0 microns for a sample of about 1000 galaxies in the GOODS-S field for which robust size measurements are available from Hubble Space Telescope Wide Field Camera 3 observations. We use Self Organizing Maps (SOMs) to map the multi dimensional photometric and galaxy size observations while taking advantage of existing spectroscopic redshifts at 0 < z < 2 for independent training and testing sets. We show that use of photometric and morphological data led to redshift estimates comparable to redshift measurements from SED modeling and from self-organizing maps without morphological measurements.

description: There is a striking suppression of the cross section for production of octet baryons in $e^+ e ^-$ annihilation, as the mass of the produced hadron increases. We present a simple parametrization for the fragmentation functions into octet baryons guided by two input models: the SU(3) flavor symmetry part is given by a quark-diquark model, and the baryon mass suppression part is inspired by the string model. We need only eight free parameters to describe the fragmentation functions for all octet baryons. These free parameters are determined by a fit to the experimental data of octet baryon production in $e^+ e ^-$ annihilation. Then we apply the obtained fragmentation functions to predict the cross section of the octet baryon production in charged lepton DIS and find consistency with the available experimental data. Furthermore, baryon production in $pp$ collisions is suggested to be an ideal domain to check the predicted mass suppression.

description: What are the key properties that a network should have to provide bounded-delay guarantees for the packets? In this paper, we attempt to answer this question. To that end, we explore the theory of bounded-delay networks and provide the necessary and the sufficient conditions required to have deterministic bounded-delays in the network. We prove that as long as a network is work-conserving, independent of the packet scheduling and queue management algorithms used in the switches, it is sufficient to shape the traffic~\textit{properly} at the edge of the network to meet hard bounded-delays in the network. Using the derived theorems, we present SharpEdge, a novel design to meet deterministic bounded-delays in the network. To the best of our knowledge, SharpEdge is the first scheme that can meet all following key properties: 1) it supports coexistence of different classes of traffic, while it can guarantee their different required bounded-delays 2) it does not require any changes in the core of the network, 3) it supports both periodic and bursty traffic patterns, and 4) it does not require any time synchronization between network devices.

description: The recent period of high and volatile food prices has cast doubt on many longstanding assumptions such as the inevitability of declining real food prices, and brought to an end a long period of food price stability. Some of the key driving forces appear to have been declines in yield growth for major commodities and the rapid growth of biofuels. Both high and volatile food prices are justly causes for concern. Key elements of the cure for high food prices include a strong focus on agricultural research and development, as well as rural development more generally, and a reconsideration of the role of biofuels. The best cures for food price volatility aim to reduce it by improving market information and reducing output volatility. Social safety nets are the best policy for coping with its effects, while the widely-used trade and storage policy measures have many complex and uncertain effects.

description: Background Metabolic plasticity mediates breast cancer survival, growth, and immune evasion during metastasis. However, how tumor cell metabolism is influenced by and feeds back to regulate breast cancer progression are not fully understood. We identify hypoxia-mediated suppression of pyruvate carboxylase (PC), and subsequent induction of lactate production, as a metabolic regulator of immunosuppression. Methods We used qPCR, immunoblot, and reporter assays to characterize repression of PC in hypoxic primary tumors. Steady state metabolomics were used to identify changes in metabolite pools upon PC depletion. In vivo tumor growth and metastasis assays were used to evaluate the impact of PC manipulation and pharmacologic inhibition of lactate transporters. Immunohistochemistry, flow cytometry, and global gene expression analyzes of tumor tissue were employed to characterize the impact of PC depletion on tumor immunity. Results PC is essential for metastatic colonization of the lungs. In contrast, depletion of PC in tumor cells promotes primary tumor growth. This effect was only observed in immune competent animals, supporting the hypothesis that repression of PC can suppress anti-tumor immunity. Exploring key differences between the pulmonary and mammary environments, we demonstrate that hypoxia potently downregulated PC. In the absence of PC, tumor cells produce more lactate and undergo less oxidative phosphorylation. Inhibition of lactate metabolism was sufficient to restore T cell populations to PC-depleted mammary tumors. Conclusions We present a dimorphic role for PC in primary mammary tumors vs. pulmonary metastases. These findings highlight a key contextual role for PC-directed lactate production as a metabolic nexus connecting hypoxia and antitumor immunity.Graphical abstract

description: Between 2017 and 2019, Oceanic Exchanges, funded through the Transatlantic Partnership for Social Sciences and Humanities 2016 Digging into Data Challenge (https://diggingintodata.org), brought together leading efforts in computational periodicals research from six countries—Finland, Germany, Mexico, the Netherlands, the United Kingdom, and the United States—to examine patterns of information flow across national and linguistic boundaries. Over the past thirty years, national libraries, universities and commercial publishers around the world have made available hundreds of millions of pages of historical newspapers through mass digitisation and currently release over one million new pages per month worldwide. These have become vital resources not only for academics but for journalists, politicians, schools, and the general public. However, these digitisation programmes share a critical weakness: the very creation of national newspapers collections obscures the fact that international news exchange was central to the nineteenth-century press. The Atlas of Digitised Newspapers and Metadata is an open access guide to digitised newspapers around the world. Its initial selection is limited in scope, being comprised of the ten databases (including the aggregator Europeana) for which we were able to secure access and licensing to the machine-readable data. Nonetheless, it aims to form the foundation of a wider mapping of collections beyond its current North Atlantic and Anglophone-Pacific focus. It brings together their histories and digitisation choices with a deeper look at the language of the digitised newspaper, the evolution of newspaper terminology and the variety of metadata available in these collections. It explores how machine-readable information about an issue, volume, page, and author is stored in the digital file alongside the raw content or text, and provides a controlled vocabulary designed to be used across disciplines, within academia and beyond.

description: The goal of this study was to analyze the impact of a newly introduced market information system “E-Soko”, on beans markets integration by comparing the period before and after the system was implemented in Rwanda. Beans, both bush and climbing, are the most important traded crop in rural areas of Rwanda, and third most important in urban areas in terms of value. Bi-weekly prices on beans were analyzed for the two time periods: one before the introduction of the market information system “E-Soko” (1999 to 2003) and another one after “E-Soko” was introduced (2007-2012) on eight markets across Rwanda for each period. Vector autregression methods were used to analyze the data and assess the level of market integration in both periods. Stationarity tests show that the price series in the period after the introduction of E-Soko (2007-2012) are all (except one) stationary, which raises the question of the market efficiency. Prices in the period before E-Soko (1999-2003) indicate a good level of integration with Musanze market leading the group. No clear conclusions were drawn from this study regarding the impact of the E-Soko market information system. More studies on beans marketing channels, mechanism of price formation (market power?) and price data collection and reporting processes are needed to elucidate some of the unclear behavior of beans prices.

description: The biomedical sciences must maintain and enhance a research culture that prioritizes rigour and transparency. The US National Institute of Neurological Disorders and Stroke convened a workshop entitled 'Catalyzing Communities of Research Rigor Champions' that brought together a diverse group of leaders in promoting research rigour and transparency (identified as 'rigour champions') to discuss strategies, barriers and resources for catalyzing technical, cultural and educational changes in the biomedical sciences. This article summarizes 2 days of panels and discussions and provides an overview of critical barriers to research rigour, perspectives behind reform initiatives and considerations for stakeholders across science. Additionally, we describe applications of network science to foster, maintain and expand cultural changes related to scientific rigour and opportunities to embed rigourous practices into didactic courses, training experiences and degree programme requirements. We hope this piece provides a primer for the wider research community on current discussions and actions and inspires individuals to build, join or expand collaborative networks within their own institutions that prioritize rigourous research practices.

description: We present an efficient method for preparing the initial state required by the eigenvalue approximation quantum algorithm of Abrams and Lloyd. Our method can be applied when solving continuous Hermitian eigenproblems, e.g., the Schroedinger equation, on a discrete grid. We start with a classically obtained eigenvector for a problem discretized on a coarse grid, and we efficiently construct, quantum mechanically, an approximation of the same eigenvector on a fine grid. We use this approximation as the initial state for the eigenvalue estimation algorithm, and show the relationship between its success probability and the size of the coarse grid.

Die Datenerfassung und – analyse in einem Geographischen Informationssystem (GIS) ermöglichte die Ableitung großformatiger thematischer Lösskarten. Daten über Lössmächtigkeiten wurden analysiert und zu einer regionalen Mächtigkeitskarte kompiliert. Zusätzlich dazu wurden zahlreiche Lössvorkommen mit anormaler Mächtigkeit aufgrund spezieller geologischer und geomorphologischer Bedingungen abgegrenzt. Mehrere Lössregionen mit unterschiedlicher granulometrischer Fazies wurden ausgeschieden. Zudem konnten regionale Lössdecken unterschiedlichen Alters kartiert werden. Die Lössdecken im nördlichen Teil des Untersuchungsgebietes haben jungweichselzeitliches Alter, dagegen wurden im Bergland Regionen mit unvollständigen und gut gegliederten weichselzeitlichen Lössabfolgen nachgewiesen. Die Ergebnisse der Untersuchung zeigen, dass auf der Grundlage veröffentlichter, heterogener Daten neue Aspekte und regionale Muster abgeleitet werden können.

description: Diatrype subundulata Lar.N. Vassiljeva & H.X. Ma, sp. nov. (Figs. 12, 21) MB 809639
 Type:— CHINA. Jilin Province: vicinity of The Red Leaves Valley of Jiaohe, Shasongling area, on dead branches of Acer mandshuricum, 30 August 2013, L. Vasilyeva, VLA P-2825, holotype!
 Differs from Diatrype undulata in larger ascospores (7–9 versus 5–7 µm long) and the restriction to Acer spp.
 Other specimens examined:— RUSSIA. Primorsky Territory: Ussuriysk Nature Reserve, on Acer sp., 18 August 1962, E. Koval, VLA P-401; on A. pseudosieboldianum (Pax) Kom., 28 April 1956, I. Bunkina, VLA P-402; Khabarovsk Territory: Big Khekhtsir Nature Reserve, on Acer sp., 27 August 1983, L. Vasilyeva, VLA P-1370; Jewish Autonomous Region, Bastak Nature Reserve, on Acer tegmentosum Maxim., 18 August 2004, L. Vasilyeva, VLA P-91.
Stromata usually widely effused, dark brown, studded with small stellate ostiloles, surrounded by a black line within the substrate; perithecia monostichous or distichous, singly erumpent, 150–200 µm diam., with short ostiolar necks. Asci cylindrical, paraphysate, 35–40 × 5–7 µm in spore bearing part, stalks of different length (up to 60 µm long), containing 8 biseriate ascospores, apical ring non-amyloid. Ascospores one-celled, allantoid, yellowish, 7–9 × 1.7–1.9 µm.
 Etymology:—Refers to the superficial similarity with Diatrype undulata.
 The similarity of stromata in Diatrype subundulata and D. undulata could be seen at Figs. 12 and 13, but these species differ in their ascospores. The specimens of D. subundulata from the south-east of Russia were wrongly identified as Diatrype spilomea Syd. (Vasilyeva 2011). The latter species has smaller ascospores comparable with those of D. undulata. The new species D. subundulata seems to be restricted to Acer spp. and the area around the Sea of Japan (north-eastern provinces of China, south of eastern Russia).

description: Der Vergleich von „multiple aliquot“ Protokoll basierten IRSL- und TL-Altern mit denen von „single aliquot regenerative“ Protokollen mittels des post-IR IRSL (225°C) und fading-korrigierten IR (50°C) zeigt, dass Signalverlust durch anomales Ausheilen für Lösse und Lössderivate des Schwalbenberg II Profils ein geringes Problem darstellt. Aus diesem Grund ist es sehr wahrscheinlich, dass auf „multiple aliquot“ Messprotokollen beruhende Lumineszenz-Datierungen, die in den 1990er Jahren im allgemeinen für Lösse aus dem Mittelrheingebiet angewendet wurden, bis zu einem Alter von 70–80 ka innerhalb der 1-sigma Fehlerabweichung verlässliche IRSL und TL-Alter ergeben haben. Die Löss-/Paläobodensedimente des Schwalbenberg II Lössprofils zeigen einen bemerkenswert detaillierte weichselzeitliche mittelpleniglaziale Abfolge, die mit dem marinen Sauerstoffisotopenstadium 3 korreliert wird. Ein verlässlicher chronologischer Rahmen wurde durch Lumineszenz-Datierungsmethoden bestimmt. Vier Löss-Hauptakkumulationsphasen konnten für die letztglaziale Abfolge vom Schwalbenberg nachgewiesen werden. Die chronologischen Ergebnisse unterstützen die litho-pedologische Korrelation der Hesbaye Formation mit MIS 2 und der Ahrgau Formation mit MIS 3. Aufgrund von litho-pedologischen Befunden wird die Keldach Formation mit MIS 4 korreliert. Die Lumineszenz-Alter von 55 bis 45 ka legen jedoch eine Korrelation mit MIS 3 nahe.

description: Egg dormancy is a key life history strategy in copepods to temporarily escape catastrophic or repetitive detrimental events and ensure permanent colonization. In Lake Biwa, although the copepod Eodiaptomus japonicus dominates the zooplankton community year-round, it has been known to produce resting eggs, yet little is known about its dormancy. To clarify the nature of dormancy in E. japonicus, we collected a sediment core from Lake Biwa, isolated resting eggs, and conducted hatching experiments to determine the life-cycle traits of the hatched individuals. We isolated 242 eggs (maximum age, 60 years) from the upper 17 cm depth sediments, and although no strict catastrophic event such as seasonal drying up was found, the findings implied that E. japonicus might have a “bet-hedging” strategy. Accumulated egg density above 17 cm was 2.5 × 104 m−2, and mean annual egg flux was 103 m−2 per year. Over the first 10 cm sediments, average egg hatching success was 17%. No egg hatchings were confirmed below 10 cm depth. Embryonic development times of the resting eggs were longer than those of subitaneous eggs, indicating that a lag phase existed until development resumed; 33% of hatched nauplii molted to adulthood, and 80% of females produced offspring. These results suggest potential recruitment from resting eggs in the bottom sediments, which partly serve as an egg bank in this copepod.

description: Intrinsic resistance to targeted therapeutics in PTEN-deficient glioblastoma (GBM) is mediated by redundant signaling networks that sustain critical metabolic functions. Here we demonstrate that coordinated inhibition of the ribosomal protein S6 kinase 1 (S6K1) and the receptor tyrosine kinase AXL using LY-2584702 and BMS-777607 can overcome network redundancy to reduce GBM tumor growth. This combination of S6K1 and AXL inhibition suppressed glucose flux to pyrimidine biosynthesis. Genetic inactivation studies to map the signaling network indicated that both S6K1 and S6K2 transmit growth signals in PTEN-deficient GBM. Kinome-wide ATP binding analysis in inhibitor-treated cells revealed that LY-2584702 directly inhibited S6K1, and substrate phosphorylation studies showed that BMS-777607 inactivation of upstream AXL collaborated to reduce S6K2-mediated signal transduction. Thus, combination targeting of S6K1 and AXL provides a kinase-directed therapeutic approach that circumvents signal transduction redundancy to interrupt metabolic function and reduce growth of PTEN-deficient GBM.

description: Electric fields are integral to numerous industrial and scientific processes that involve multiphase complex
fluid systems; for example, electrocoalescence,
electro-emulsi cation and dielectrophoretic manipulation in micro fluidic devices. In these processes, electric fi elds deform, break and coalesce fluid interfaces. These systems contain surface-active species, or surfactants, which
simultaneously transport to the interface. To engineer the system response, the deformation, conditions for instability of the interface and the transport of surfactant under electric fields needs to be quanti fied. In this thesis, we analyze the response of liquid drops, and surfactant transport to interfaces under electric fields. The impact is prediction of drop behavior in devices and development of a unique tool to engineer and manipulate liquid-liquid interfaces.
We fi rst employ boundary integral computations to highlight the role of convection of surface charges in the transition in breakup mode of a weakly conducting drop suspended in another weakly conducting drop, under a uniform electric field. Accumulation of surface charges at the tips of the drop
results in an abrupt change from a breakup mode characterized by bulbous lobes to one distinguished by the formation of conical tips. We next model interaction between multiple conducting drops and disturbances in operating
conditions as temporal fluctuations in the electric field. We use small deformation theory and the boundary integral method to predict the transient deformation and criterion for breakup of the drop under a random electric field. We demonstrate that fluctuations in the external electric field increase the average drop deformation, reduce the time for breakup, and soften the transition from steady state to breakup. We then probe the addition of soluble
surfactants to the drop phase in terms of the eff ective viscosity of a dilute emulsion of such drops. Small amounts of added surfactant can greatly impact the viscosity of the emulsion for certain regimes of surfactant transport and
depletion. We then proceed to develop an experimental platform to quantify the transport of surfactants to an oil-water interface under electric fields. We show that surfactants that form charge carriers in an oil phase show an enhanced transport under electric fields. Moreover, the fi eld selectively aff ects surfactant transport in the oil phase. In summary, using theory, computation and experiment, we make signi ficant contributions to underline the ability of
electric fields to manipulate liquid-liquid interfaces.

description: Tournaisian-age failure of marginal lacustrine sediments, and their bulk collapse into an inland rift-basin lake in the Moncton Subbasin, Canada, led to the entrainment of rare, almost complete, three-dimensionally preserved non-woody trees. Preservation of these unique fossils from the Albert Formation was a consequence of contemporaneous seismicity. Synsedimentary structures include an array of soft-sediment deformational features and a field of cross-cutting sand boils indicating multiple seismic shocks >4.6 Mw. This tectonically controlled event, entombing trees whose novel growth form is both evolutionarily and ecologically transitionary and unlike other Paleozoic plants, is a one-off in the paleobotanical record.

description: Der vorliegende Artikel gibt einen Überblick über neu datierte Abschnitte in bekannten Löss/Paläoboden-Sequenzen Niederösterreichs. Die Ergebnisse der Datierungen im Profil Joching deuten darauf hin, dass es im letzten Hochglazial zur Lösssedimentation kam. Die meisten erfassten Alter sind jedoch älter als das letzte Hochglazial, was auf Erosionsprozesse hindeutet, die zur Abtragung der jüngeren Lösse geführt hat. In dem Abschnitt zwischen ~28 ka and ~35 ka wurden überwiegend Tundragleye gebildet. Eine intensivere interstadiale Bodenbildung ist nicht nachzuweisen. Dieses Ergebnis kann auch für die stratigraphische Einstufung von ‚Stillfried B‘ (sensu Fink) von Bedeutung sein. Der folgende chronologische Abschnitt liegt zwischen ~35 ka and ~57 ka in Lösssedimenten mit eingeschalteten Tundragleyen. Auch dieser Abschnitt ist durch Umlagerungsprozesse charakterisiert. Im Zeitraum von ~57 ka bis ~106 ka befindet sich eine markante Zeitlücke, die vermutlich auf langandauernde und intensive Erosionsprozesse im Untersuchungsgebiet zurückzuführen ist. Die älteste Datierung in den Sedimenten des letzten Glazials mit 106 ± 12 ka befindet sich in Paudorf direkt über dem ‚Stillfried A‘- Komplex (Paudorfer Bodenbildung). Direkt unter diesem Pedokomplex, bzw. vergleichbaren Pedokomplexen treten in Lössablagerungen Alter von 124 ± 2 5 ka (Göttweig-Aigen), 159 ± 20 ka (Paudorf 1), and 170 ± 16 ka (Joching) auf. Darüber hinausgehende Alter konnten in Stratzing, Paudorf 2, Göttweig-Furth und Langenlois nachgewiesen werden.
