description:
Chemical weathering of silicate minerals plays a vital role in maintaining the long-term habitability of Earth’s climate over geological timescales via a negative feedback mechanism. But much debate concerns the response strength of silicate weathering to each climatic factor and its evolution with land surface reorganisation. Such discrepancy arises from lacking weathering proxy validation and scarce quantitative paleo-constraints on individual forcing factors. Here we examine the catchment-scale link of silicate weathering intensity with various environmental parameters using a global compilation of modern sediment dataset for calculation of weathering intensity proxies, including chemical index of alteration (CIA) and weathering index of Parker (WIP).

We show the primary control of temperature on silicate weathering given the monotonic increase of feldspar dissolution (constrained by CIA) with it at 0-30 oC, while controls of precipitation or topographic-lithological factors are regional and subordinate1. We interpret the non-linear forcing of temperature on feldspar dissolution as depletion of more reactive plagioclase (relative to orthoclase) at higher temperature. Accordingly, the surface temperature decrease could be accompanied with a higher proportion of more reactive plagioclase available for weathering, supporting the hypothesis that land surface reactivity has increased during the late Cenozoic cooling2. We also propose a first-order quantitative relationship between surface temperature, feldspar dissolution and CO2 consumption that will be of great potential for deep-time temperature reconstruction and carbon cycle modeling.

description: One of the important issues in nanomagnetism is to lower the current needed for a technologically useful domain wall (DW) propagation speed. Based on the modified Landau-Lifshitz-Gilbert (LLG) equation with both Slonczewski spin-transfer torque and the field-like torque, we derive the optimal spin current pattern for fast DW propagation along nanowires. Under such conditions, the DW velocity in biaxial wires can be enhanced as much as ten times compared to the velocities achieved in experiments so far. Moreover, the fast variation of spin polarization can help DW depinning. Possible experimental realizations are discussed.

description:
Islands are interesting geomorphic features because they possess a well defined base level. Non-volcanic islands, in particular, are the product of rifting of a small continental fragment such that they start their geomorphic evolution as a more or less elevated flat plateau. After tens of millions of years of evolution, some islands, such as Madagascar, still present a Pi-shaped form composed of large watersheds on top of a central plateau surrounded by smaller ones that connect the plateau to the coastline. Other islands, such as Sri Lanka have a more conical or Lambda-shape composed of a radial distribution of basins connecting the island summit to the coastline. Here we investigate the conditions that lead to the transformation of an initially plateau-shape island to either a Pi- or Lambda-shape by using a Landscape Evolution Model solving the Stream Power Law and talking into account flexural isostasy.

We find that to maintain a Pi-shape, an island must fulfil two criteria: firstly, its extent must be sufficiently large in comparison with the underlying effective elastic thickness (EET), and, secondly, it must be subjected to limited erosion. We introduce a morphometric index that allows to discriminate between the two types of morphologies and show how it evolves through time as a function of both EET and erodibility.

Constraining the time evolution of the morphology of an island is important to study the evolution of its bio-diversity. Our finding implies that the micro-endemism that characterises Madagascar is linked to the strength of the underlying lithosphere.

description: The silicon vacancy is a prominent intrinsic defect of cubic SiC (3C-SiC) to which much effort has been devoted so far, experimentally and theoretically. We calculate its properties using the GW approximation that does not suffer from the band gap problem. The obtained formation and transition energies deviate significantly from the usual density functional theory evaluations and now compare favorably with experiment. A new assignment for the main line of photoluminescence is then proposed. We further perform GW calculations for the saddle point of reaction paths. The resulting barrier energies explain the thermal annealing experiments thanks to an original mechanism mediated by a minority charge configuration.

description: With the explosion of wireless networks and automotive radar systems, there is an acute need for new materials and technologies that would not only minimize the size of these devices, but also enhance their performances. The technique of transformation optics-an innovative approach to produce artificial metamaterials that control electromagnetic waves as if space itself was transformed-provides unique opportunities to reach this goal. In this paper we design, fabricate and characterize a new class of metamaterial capable of transforming the source distribution and radiation pattern of an isotropic microwave emitter. Our findings have considerable implications for the development of new ultradirective antennas with superior performances and compactness compared to conventional antennas operating in the same frequency range.

description:
Most islands host an endemic biota, i.e., present nowhere else on Earth. This is the case, for instance, of Madagascar. It has been shown that different populations of lemurs, endemic to the island, are mostly distributed along the watersheds surrounding Madagascar, creating a so-called micro-endemism, while the populations living on the high-elevated watersheds, on the central plateau, are not showing this micro-endemism. Here we wish to address the question whether there exists a correlation between the evolution of the landforms (i.e., the geometry of the watersheds) of Madagascar and the hybrid evolution of lemur populations? More broadly, can the tectono-geomorphic evolution of an island be advantageous or disadvantageous to the flourishing of micro-biodiversity?

To answer these questions in a quantitative manner, we combined a Landscape Evolution Model based on the Stream Power Law and taking into account flexural isostasy, with a speciation model. We first developed a morphometric index to differentiate between islands with a central plateau surrounded by smaller basins, like Madagascar, from conical islands, like Sri Lanka. We then predicted patterns of biodiversity as a function of the index value and its time evolution. We show that for the tectono-geomorphic evolution to influence patterns of biodiversity requires a specific range of model parameter values, in particular the parameters characterising dispersal and mutation. We finally used phylogenetic observations to constrain some of these parameters.

description: The angular dependence of the remanence and coercivity of Ni nanowire arrays produced inside the pores of anodic alumina membranes has been studied. By comparing our analytical calculations with our measurements, we conclude that the magnetization reversal in this array is driven by means of the nucleation and propagation of a transverse wall. A simple model based on an adapted Stoner-Wohlfarth model is used to explain the angular dependence of the coercivity.
Characterizing host protein post-translational modification in pathogenic Escherichia coli infection
Creators: name: Santos, Andrew Stanislaw
Publisher: name: University of British Columbia
Year: 2024

description: Enteropathogenic Escherichia coli (EPEC) is a bacterial pathogen that causes significant morbidity and mortality worldwide. During infection, EPEC attaches to the intestinal epithelium and uses a molecular syringe-like nanomachine called a Type 3 Secretion system (T3SS) to secrete virulence ‘effector’ proteins directly into human cells, where they manipulate host cell signalling and mediate the characteristic features of infection, including intimate attachment to host cells, formation of actin-rich pedestals, disruption of the epithelial barrier, and dysregulated immune function and cell survival. Some effectors possess enzymatic activities that allow them to directly modify host proteins through post-translational modifications, including ubiquitination, phosphorylation, and proteolysis. However, the host targets of many effectors are unknown and their collective impact on global host post-translational modification has not been widely explored. This work utilizes proteomics tools to characterize the impact of EPEC infection and T3SS effectors on the host proteome. Here, ubiquitin proteomics were used to investigate the EPEC effector ubiquitin ligase NleG, exploring its impact on the host ubiquitome, and identifying and characterizing the relationship of NleG with a novel host substrate: Ataxin-3. We also developed a novel EPEC infection-proteomics workflow to characterize global changes in host protein post-translational modifications during important stages of infection. This method simultaneously profiled changes in protein abundance, ubiquitination, and phosphorylation due to EPEC infection, T3SS effector influences, and host response during early, mid-, and late infection. Infection-proteomics exhibited the highest coverage of the host proteome, ubiquitome, and phosphoproteome of any EPEC proteomics investigation to date, identifying thousands of EPEC infection-, exposure-, and T3SS-associated changes in proteins involved in cell processes regulated by EPEC during infection. These include innate immune signalling, actin remodelling, and cell survival pathways, while also identifying novel pathways targeted by EPEC. This work demonstrates the power of proteomics techniques to characterize impacts of EPEC infection on the host proteome by developing a novel approach to study how EPEC infection and effectors affect host post-translational modification and cell signalling throughout infection. Proteomics tools serve as valuable methods to study host-pathogen interactions and identifying molecular level changes underpinning characteristic phenotypes mediated by EPEC during infection.

description:
The poster presents the framework of the modeling part of the BMWi-funded project "Li-Fluids" (grant number: 03EE4034A). It introduces PHREEQC modeling approaches for simulating lithium-bearing minerals in geothermal reservoirs. By integrating lithium sources into PHREEQC, the release of lithium can be simulated. Additionally, a 1D dual-porosity approach is used to define reservoirs and calculate time-dependent depletion.

However, there are challenges. The accurate calculation of brines requires the Pitzer approach, which is limited in the number of minerals considered and does not include aluminum. Li-Mica, a modified form of K-Mica, appears to be an important primary source of lithium in the host rock. To address these limitations, other databases like the SIT database can be extended to include lithium-bearing aluminum silicates.

Saturation experiments were conducted up to 200°C using pure H2O, approximating the observed Li+ concentrations from gold capsule experiments conducted by the project partner BGR. These concentrations ranged from a few mg/l Li+. Since Al3+ is necessary for calculating the saturation indices of Li+-bearing aluminum silicates, the use of pure H2O was necessary to combine the BGR's laboratory experiments with PHREEQC's capabilities.

The next step involves implementing reservoir properties and developing an approach for modeling transport using concentrated saline waters frequently encountered in deep sedimentary basins in Germany. Van Genuchten's (1985) approach, which incorporates dual porosity similar to sedimentary rocks, will be utilized in PHREEQC. This hydraulic extension, combined with deep saline waters (e.g., the North German Basin), facilitates the extrapolation of findings from pure water experiments to a quasi-reservoir.

description:
The Adriatic seascape, as the Mediterranean’s northernmost extension, has long been an important crossroad of cultural exchanges between the East and the West. Here, connectivity and insularity served to link diverse peoples and cultures, with regional connectivity reaching its peak during the Iron Age. Concurrently, the Greeks embarked on extensive overseas journeys and established numerous settlements across the Mediterranean. One fascinating example to explore the dynamics between the locals and Greek colonists is the island of Hvar in central Dalmatia, which offers valuable insights through the examination of ceramic material culture. Using a range of traditional and state-of-the-art microscopic and spectroscopic analyses, a wide range of Greek and local Iron Age coarseware from the Greek colony of Pharos and local indigenous settlements was examined, with a particular emphasis on the practices involved in raw materials selection. A novel method for collecting elemental concentration data was implemented, which concentrates exclusively on the clayey substrate. This approach effectively mitigates any potential bias arising from the tempering of clay paste. Additionally, we conducted a geological survey of the island to identify plausible raw material deposits, considering that coarseware was predominantly produced locally. The findings of our study provide fresh perspectives on the lives of protohistoric local communities and their interactions with Greek settlers for whom the island of Hvar served as a hub from which Hellenistic culture spread throughout the insular and coastal Adriatic regions and beyond.

description:
Land-ocean interactions in the coastal zone are of particular interest regarding the exchange of substances, like nutrients, carbon, sulfur, metals, and water. The rising sea level is and will enhance the pressure of salty solutions on previously fresh water ecosystems. Currently coastal areas in the North Eastern part of Germany under increasingly rewetted by the connection with the brackish Baltic Sea. We present results on the isotope biogeochemistry of a modern rewetted wetland, at the southern Baltic Sea, the Huetelmoor, that is under impact by event-type flooding by brackish seawater. These events lead to an enhancement of sulfate availability for microbial carbon transformations. Sediment cores on transects within the wetland were investigated for the pore water and soil composition, together with selected ground water wells and surface waters from the channeling system. Different fractions of the soils were analyzed for the elemental composition, mineral micro-textures, and the stable sulfur (and oxygen) isotope composition of different sulfur fractions to understand the water and biogeochemical carbon-sulfur-metal cycles and the geochemical signatures in authigenic mineral phases and organic matter. Adding sulfate creates space for mineral authigenesis and organic matter sulfurization. The soils are impacted by different intensities in sulfur cycling as reflected by isotope and textural signals. Further mechanistic investigations consider the role of DOS upon changing sulfur substrate availability. Results allow for a transfer of proxy information to other modern and past coastal organic-rich peatlands.

description: We study charged particle motion in weakly charged higher dimensional black holes. To describe the electromagnetic field we use a test field approximation and use the higher dimensional Kerr-NUT-(A)dS metric as a background geometry. It is shown that for a special configuration of the electromagnetic field the equations of motion of charged particles are completely integrable. The vector potential of such a field is proportional to one of the Killing vectors (called primary Killing vector) from the `Killing tower' of symmetry generating objects which exists in the background geometry. A free constant in the definition of the adopted electromagnetic potential is proportional to the electric charge of the higher dimensional black hole. The full set of independent conserved quantities in involution is found. It is demonstrated, that Hamilton-Jacobi equations are separable, as well as the corresponding Klein-Gordon equation and its symmetry operators.

description: Abstract- Throughout the history of the ascent of cognitive sciences, cells of the robust and rather resourceful bio-entity we call the brain have enjoyed particular attention, deliberation and scrutiny. Among these are the tiles that pile up throughout CNS by outnumbering neurons fivefold, called Astrocytes. (Michael V et al 2009) [1] Astrocytes played a passive role in the learning of neuroscience, however, recent studies have invoked compelling novelty that attends more to their contribution as astrocyte-assisted neural signalling, astrocyte-associated immunological activity (Dong et al 2001) [2] and Ca-based form of excitability (Fiacco TA et al 2008). [3] This article will explore the contrast among the historical remodelings regarding the understanding of astrocyte molecular biology while focusing on the review of avant-garde updates central to astrocyte functioning. It is already well put by Harold K Kimelberg (2004) [4], “Astrocytes had been the initial neuroglia of Ramón y Cajal but even after 100 years there is no adequate interpretation of what should comprise these cells,” Surely more systematic examination into this would extract an integrated and thorough understanding of astrocytes but this could borrow more time, perhaps years. This article puts into perspective, the manifold scope of astrocyte biology by producing organized discussions regarding several essential themes such as astrocytes as intermediaries to the regulation of neurodegenerative diseases, neural modulation and discoveries of astrocyte-associated therapeutic targets.

description: In order to illustrate the emergence of Coulomb blockade from coherent quantum phase-slip processes in thin superconducting wires, we propose and theoretically investigate two elementary setups, or "devices". The setups are derived from Cooper-pair box and Cooper-pair transistor, so we refer to them as QPS-box and QPS-transistor, respectively. We demonstrate that the devices exhibit sensitivity to a charge induced by a gate electrode, this being the main signature of Coulomb blockade. Experimental realization of these devices will unambiguously prove the Coulomb blockade as an effect of coherence of phase-slip processes. We analyze the emergence of discrete charging in the limit strong phase-slips. We have found and investigated six distinct regimes that are realized depending on the relation between three characteristic energy scales: inductive and charging energy, and phase-slip amplitude. For completeness, we include a brief discussion of dual Josephson-junction devices.

This study focuses on the investigation of scour depth around a complex pier featuring a nine-pile group configuration. The primary objective was to develop a scour depth equation specific to this complex pier setup using regression analysis techniques. The research employed MATLAB for comprehensive data analysis, enabling the derivation of a robust mathematical model to predict scour depths. By exploring the intricacies of scour patterns around complex pier structures, this study contributes valuable insights into coastal and hydraulic engineering practices, aiding in the design and management of resilient pier foundations in dynamic aquatic environments.

description: Commonly observed patterns typically follow a few distinct families of probability distributions. Over one hundred years ago, Karl Pearson provided a systematic derivation and classification of the common continuous distributions. His approach was phenomenological: a differential equation that generated common distributions without any underlying conceptual basis for why common distributions have particular forms and what explains the familial relations. Pearson's system and its descendants remain the most popular systematic classification of probability distributions. Here, we unify the disparate forms of common distributions into a single system based on two meaningful and justifiable propositions. First, distributions follow maximum entropy subject to constraints, where maximum entropy is equivalent to minimum information. Second, different problems associate magnitude to information in different ways, an association we describe in terms of the relation between information invariance and measurement scale. Our framework relates the different continuous probability distributions through the variations in measurement scale that change each family of maximum entropy distributions into a distinct family.

For the southern part, benthic DIC sources have been identified [1], with tidal areas being further hot spots [2], some being impacted by submarine fresh water discharge [3]. The Skagerrak provides the unique opportunity of studying benthic DIC production under the impact of different dominant electron acceptors [4]. Potential transformation of carbonates may impact release of TA and DIC.

Here, we investigated the role of different sediments from the North Sea, including tidal areas, for their DIC source function and carbon storage capacity. Water column, pore water, and sediment samples were investigated to understand the processes controlling the benthic production and release of TA and DIC. The carbon isotope composition of dissolved and solid phases were investigated to understand the specific biogeochemical processes dominating benthic mineralization and carbonate dissolution.

description: We report on the measurements of the superconducting order parameter in the nonmagnetic borocarbides LuNi$_2$B$_2$C and YNi$_2$B$_2$C. Andreev conductance spectra are obtained from nanoscale metallic junctions on single crystal surfaces prepared along three major crystallographic orientations: [001], [110], and [100]. The gap values extracted by the single-gap Blonder-Tinkham-Klapwijk model follow the BCS predictions as a function of temperature and magnetic field and exhibit a small anisotropy. These observations are robust and reproducible among all the measurements on two different sets of LuNi$_2$B$_2$C crystals and one set of YNi$_2$B$_2$C crystals. We suggest possible explanations for the small gap anisotropy based on the recent detailed gap measurements by angle-resolved photoemission spectroscopy and the tunneling cone effect. Our results provide a consistent picture of the superconducting gap structure in these materials, addressing the controversy particularly in the reported results of point-contact Andreev reflection spectroscopy.

description:
The Kallar Kahar area falls in the sub-Himalayas. The structural geometry of the area has been assessed using geological mapping and structural analysis. At the surface the study area comprises of the rock units ranging in age from Precambrian to Pliocene with several major unconformities. The Precambrian Salt Range Formation is exposed in the form of diapiric intrusions. The strike slip Kallar Kahar Fault (KKF) controls the structural fabric of the area. It is a NW-SE trending structure characterized by an overall transpressional tectonics with a right lateral strike slip component. An en echelon pattern of NW-SE trending folds, a back thrust and a couple of fore thrusts occurs in the immediate south of the Kallar Kahar Lake. These thrusts are out of sequence thrusts cutting up section the thrust sheet of the Salt Range Thrust (SRT). The fore-thrusts represents a relatively younger phase of deformation than the back thrust as the former cross cut the later one. These folds and faults formed as a result of transpression associated with a left step over along the KKF. The rigorous compressional structures in the southeastern portion of the mapped area, and a clear discontinuity on the Landsat images are in line with the presence of a left step over along the KKF. The restraining along this stepover during ramping along the SRT, resulted in salt diapirism in the area. The KKF is believed to have formed to accommodate the variable stresses generated during the differential propagation of the SRT’s thrust sheet.

description: Nonlinear electrical properties of graphene-based three-terminal nanojunctions are presented. Intrinsic rectification of voltage is observed up to room temperature. The sign and the efficiency of the rectification can be tuned by a gate. Changing the charge carrier type from holes to electrons results in a change of the rectification sign. At a bias < 20mV and at a temperature below 4.2K the sign and the efficiency of the rectification are governed by universal conductance fluctuations.

description:
The tectonics on the Archean Earth is intricate and contentious, with ongoing debate concerning the dominant surface processes controlled by either a plate tectonics regime or alternative forms of tectonics (stagnant lid, heat pipe, drip tectonics, sluggish plates and other planetary modes of heat loss). In this study, we assess the viability of interpretations of tectonics during the Archean using a newly compiled metamorphic database. We relate Archean cratons and continental history, crustal growth and reworking, and horizontal motion of ancient cratons to infer which tectonic styles and processes operated. Our analysis is synthetized by the highlighting of three distinct Archean periods with different tectonic activity, starting at 3.8 billion years (Ga), from when the first metamorphic data are available. We find that in the interval 3.8-3.5 Ga, tectonics was dominated by short-lived subduction tectonics and non-subduction tectonics, possibly in cohabitation. Between 3.4 and 3.0 Ga, subduction was present and contributed to the lateral growth of the continents. In the 2.8-2.5 Ga period, the assembly of supercontinent/supercratons signals the action of modern-style plate tectonics. In summary Archean metamorphic data allow timing the Earth progression from pre-modern tectonics to modern plate tectonics including the supercontinent cycle.

description: Observations of Plutino 2003 AZ84 suggest it could share similar properties to Orcus, or even Pluto’s satellite Charon. Because it is smaller, hence fainter, its surface composition could not be constrained from ground-based spectroscopy.
 The JWST/NIRSpec instrument was thus used to target 2003 AZ84, using the Fixed Slit (FS) mode, with both low and medium spectral resolutions, from 0.6 to 5.3 microns. To avoid any loss of spectral information, an optimal processing of these FS data is necessary. In this work, we propose such an optimal spectra extraction method, using an inverse problem approach. For each wavelength, the data acquired on the detector are considered as a 1D spatial Point Spread
 Function (PSF), with the amplitude giving the spectral value for this wavelength, plus some additive noise. A thorough model of the spatial PSF is thus essential to ensure the optimal processing. The spectrum is then extracted by minimizing the co-log-likelihood of the data, with an additive regularization term, to avoid noise amplification in the extraction. We present the results of our method for the spectra extraction of 2003 AZ84, and compare them to the spectra obtained with the JWST/NIRSpec pipeline, where the spectrum is extracted by integrating the flux in fixed size small aperture.
