description: Layer-by-layer assembly of van der Waals (vdW) heterostructures underpins new discoveries in solid state physics, material science and chemistry. Despite the successes, all current 2D material (2DM) transfer techniques rely on the use of polymers which limit the cleanliness, ultimate electronic performance, and potential for optoelectronic applications of the heterostructures. In this article, we present a novel polymer-free platform for rapid and facile heterostructure assembly which utilises re-usable flexible silicon nitride membranes. We demonstrate that this allows fast and reproducible production of 2D heterostructures using both exfoliated and CVD-grown materials with perfect interfaces free from interlayer contamination and correspondingly excellent electronic behaviour, limited only by the size and intrinsic quality of the crystals used. Furthermore, removing the need for polymeric carriers allows new possibilities for vdW heterostructure fabrication: assembly at high temperatures up to 600°C, and in different environments including ultra-high vacuum (UHV) and when the materials are fully submerged in liquids. We demonstrate UHV heterostructure assembly for the first time, and show the reliable creation of graphene moiré superlattices with more than an order of magnitude improvement in their structural homogeneity. We believe that broad adaptation of our novel inorganic 2D materials assembly strategy will allow realisation of the full potential of vdW heterostructures as a platform for new physics and advanced optoelectronic technologies.

Gauge Invariant Linear Response Theory of Relativistic BCS superfluids

description: We develop a gauge-invariant linear response theory for relativistic Bardeen-Cooper-Schrieffer (BCS) superfluids based on a consistent-fluctuation-of-the order-parameter (CFOP) approach. The response functions from the CFOP approach satisfy important generalized Ward identities. The gauge invariance of the CFOP theory is a consequence of treating the gauge transformation and the fluctuations of the order parameter on equal footing so collective-mode effects are properly included. We demonstrate that the pole of the response functions is associated with the massless Goldstone boson. Important physical quantities such as the compressibility and superfluid density of relativistic BCS superfluids can also be inferred from our approach. We argue that the contribution from the massless Goldstone boson is crucial in obtaining a consistent expression for the compressibility.

description: No abstracts are to be cited without prior reference to the author.Satellite data and operational ocean models provide the necessary inputs for ecosystem models of the lower to mid and upper trophic levels. One key explanatory variable that is usually missing but important for an understanding of the dynamics of key exploited or protected marine species is the dynamic of the micronekton that is at the mid-trophic level (MTL) in the ecosystem. This includes both prey of large predators and predators of eggs and larvae of fish. We present the development of an operational model of mid-trophic functional groups driven by physical and biogeochemical variables. Once a reasonable prediction of MTL organisms is achieved, the number of applications for near real-time management and monitoring of marine ecosystems and resources should increase rapidly, as illustrated by the examples provided here. This includes the prediction of feeding and spawning habitats for many exploited and protected species, their movements and spatial distributions, and their population dynamics under the combined effects of natural (climate variability) and anthropogenic forcings (fishing, climate warming).

description: Lithium abundances in open clusters are a very effective probe of mixing processes, and their study can help to understand the large depletion of lithium in the Sun. Due to its age and metallicity, the open cluster M67 is especially interesting on this regard. Many studies on lithium abundances in M67 have already been performed, but a homogeneous global analysis of lithium in stars from subsolar up to the most massive members, was never accomplished for a large sample based on high-quality spectra. We tested our non-standard models, which were calibrated using the Sun with observational data. We collected literature data to follow, for the first time in a homogeneous way, NLTE lithium abundances of all observed single stars in M67 more massive than about 0.9 solar masses. Our grid of evolutionary models were computed with non-standard mixing at metallicity [Fe/H] = 0.01, using the Toulouse-Geneva evolution code. The analysis is started from the entrance in the ZAMS. Lithium in M67 is a tight function of mass for stars more massive than the Sun, apart of a few outliers. A plateau in lithium abundances is observed for turn-off stars. Both less massive and more massive stars are more depleted than those in the plateau. There is a significant scatter in lithium abundances for any given mass lower than M <= 1.1 solar masses. Our models qualitatively reproduce most of the features described above, although the predicted depletion of lithium is 0.45 dex smaller than observed for masses in the plateau region, i.e. between 1.1 and 1.28 solar masses. Clearly, more work is needed to throughly match the observations. Despite hints that chromospheric activity and rotation play a role in lithium depletion, no firm conclusion can be drawn with the presently available data.

description: Recently, we showed that parathyroid hormone-like hormone (PTHLH), a cytokine-like polyprotein, is critical for extracellular matrix (ECM) deposition through the activation of hepatic stellate cells (HSCs). Here, we show that N-terminal PTHLH is secreted into the supernatant of injured hepatocytes, its expression is positively correlated with liver fibrosis severity based on mice liver biopsies, and it is primarily expressed in the cytoplasm of hepatocytes along the fibrous septa of fibrotic livers. PTHLH overexpression in mice was achieved through adeno-associated virus-mediated gene delivery (AAV9-PTHLH), and liver fibrosis was induced with carbon tetrachloride (CCl4). We observed that AAV9-PTHLH induced spontaneous development of liver fibrosis and increased sensitivity to CCl4. PTHLH increased Hedgehog (Hh) pathway activation in a PTH1R-dependent manner, and the effect of PTHLH was primarily mediated by protein kinase C (PKC) θ. PTHLH-mediated PTH1R-PKC θ pathway activation is a key event in the profibrotic Hh-dependent activation of HSCs.

description: We present ab initio and k.p calculations of the spin texture on the Fermi surface of tensile strained HgTe, which is obtained by stretching the zincblende lattice along the (111) axis. Tensile strained HgTe is a semimetal with pointlike accidental degeneracies between a mirror symmetry protected twofold degenerate band and two nondegenerate bands near the Fermi level. The Fermi surface consists of two ellipsoids which contact at the point where the Fermi level crosses the twofold degenerate band along the (111) axis. However, the spin texture of occupied states indicates that neither ellipsoid carries a compensating Chern number. Consequently, the spin texture is locked in the plane perpendicular to the (111) axis, exhibits a nonzero winding number in that plane, and changes winding number from one end of the Fermi ellipsoids to the other. The change in the winding of the spin texture suggests the existence of singular points. An ordered alloy of HgTe with ZnTe has the same effect as stretching the zincblende lattice in the (111) direction. We present ab initio calculations of ordered Hg_xZn_1-xTe that confirm the existence of a spin texture locked in a 2D plane on the Fermi surface with different winding numbers on either end.

description: Presentation given by Dr Samantha P. Kanza on behalf of PSDI at ACS Fall 2023. Abstract: The Semantic Web was originally introduced as enabling "machines to interpret data with the same level of intelligence as a human being" with grand promises of an almost sentient web that could seamlessly link data together to produce insights and services beyond your wildest dreams. Fast forward 20 years and it's safe to say, that has not happened. However, that does NOT mean that the Semantic Web is without its uses, it has been misrepresented, misunderstood, and neglected with respect to nurturing its growth and enabling its potential. 
This talk will discuss how and why the Semantic Web can be useful but will also describe the current issues both in terms of the currently available Semantic Web Toolkit and the limitations of its technologies.
The Semantic Web holds a great deal of potential, in terms of interoperable data representation, the capacity to make inferences, providing context and meaning to data and enabling the use of AI/ML technologies on semantically rich datasets. However, there are several issues with these technologies. There is an over saturation of ontologies, and yet somehow when searching for viable ones to use within projects, the "let's just make a new one" option is often the solution, so what can we do to address this? Ontologies don't typically enable the representation of complex numerical data and seem better served to represent static rather than temporally changing data. Further, we are lacking in formal tools and methods to create linked data in the first place. These are just some of the issues and questions that will be addressed in this presentation, as we provide a whirlwind tour to the current state of Semantic Web Technologies.

description: No abstracts are to be cited without prior reference to the author.As high-resolution physical circulation models in Irish waters have improved, there is a growing demand for operational outputs and products from these models. A regional physical model (ROMS) produces a 7-day forecast for Irish waters daily. Several nested models with a horizontal resolution of several hundred metres have been developed for coastal areas such as Connemara, Bantry, and Killary Harbour. Several applications have been based on forecast and hindcast model output to date. Model flowfields that include the effects of river discharges, meteorological conditions, and wider field oceanographic conditions have been used to accurately define epidemiological units around individual finfish aquaculture sites. In the event of a fish disease outbreak, this information supports decision-making regarding movement of fish and fallowing of sites. In forecast mode, this tool will be used as a real-time decision support tool for the aquaculture industry. Similarly, models have been used in hindcast mode to examine the distribution and transport of sea lice between salmon farming sites. Varying resolution models have been compared to assess the accuracy of hindcasts and predictions under different forcing conditions. Finally, model currents are used to hindcast harmful algal bloom events off southwest Ireland in 2009 to examine transit times of harmful algae from inoculation areas in the Celtic Sea to shellfish and finfish sites in Bantry Bay. This complements a short-range model developed for Bantry based on shifts in wind direction that accurately predicts the onset of toxic algal events in several previous years.

description: In the literature on spatial point processes, there is an emerging challenge in studying marked point processes with points being labelled by functions. In this paper, we focus on point processes living on linear networks and, from distinct points of view, propose several mark summary characteristics that are of great use in studying the average association and dispersion of the function‐valued marks. Through a simulation study, we evaluate the performance of our proposed mark summary characteristics, both when marks are independent and when some sort of spatial dependence is evident among them. Finally, we employ our proposed mark summary characteristics to study the spatial structure of urban cycling profiles in Vancouver, Canada.

description: We present a novel and simple method of stabilizing the laser phase and frequency by polarization spectroscopy of an atomic vapor. In analogy to the Pound-Drever-Hall method, which uses a cavity as a memory of the laser phase, this method uses atomic coherence (dipole oscillations) as a phase memory of the transmitting laser field. A preliminary experiment using a distributed feedback laser diode and a rubidium vapor cell demonstrates a shot-noise-limited laser linewidth reduction (from 2 MHz to 20 kHz). This method would improve the performance of gas-cell-based optical atomic clocks and magnetometers and facilitate laser-cooling experiments using narrow transitions.

description: Quantum technologies are advancing from fundamental research in specialized laboratories to practical applications in the field, driving the demand for robust, scalable, and reproducible system integration techniques. Ceramic components can be pivotal thanks to high stiffness, low thermal expansion, and excellent dimensional stability under thermal stress. Lithography‐based additive manufacturing of technical ceramics is explored, especially for miniaturized physics packages and electro‐optical systems. This approach enables functional systems with precisely manufactured, intricate structures, and high mechanical stability while minimizing size and weight. It facilitates rapid prototyping, simplifies fabrication and leads to highly integrated, reliable devices. As an electrical insulator with low outgassing and high temperature stability, printed technical ceramics such as Al2O3${\rm Al}_2{\rm O}_3$and AlN bridge a technology gap in quantum technology and offer advantages over other printable materials. This potential is demonstrated with CerAMRef, a micro‐integrated rubidium D2 line optical frequency reference on a printed micro‐optical bench and housing. The frequency instability of the reference is comparable to laboratory setups while the volume of the integrated spectroscopy setup is only 6mL$6 \,\mathrm{m}\mathrm{L}$. Potential for future applications is identified in compact atomic magnetometers, miniaturized optical atom traps, and vacuum system integration.

description: The history of communications in the United States is a relatively uncultivated field. Generalizations abound yet conceptual frameworks are few. This essay contends that the history of the country's dominant communications networks can be understood as a chapter in the history of government-business relations, or what contemporaries would have called political economy. In the long nineteenth century that began in 1788 and ended in 1914, the three most important communications networks—that is, the mail, the telegraph, and the telephone—were shaped not only, or even primarily, by technological imperatives and economic incentives, but also by the regulatory regimes in which they were embedded.

description: Recycling nutrients from human faeces is a practicable and effective process in terms of the circular economy. To test this, we carried out a pot experiment with a hygienized human faeces compost (HHFC) and a nitrified urine fertilizer (NUF) made from contents of dry toilets to determine the short‐term fertilizer addition effect. HHFC variants were created in increments equivalent to 10, 20, and 30 t ha −1 dry matter weight (DM) and as joint fertilizer application of HHFC and NUF. For the classification of the fertilizer addition effect, soluble concentrations of nitrogen, phosphorus, and potassium in the soil as well as contents in the plant ( Zea mays L.) were analysed after a trial period of 8 weeks. Above‐ground biomass, plant height, and chlorophyll content of the leaves were also assessed. The sole compost variants showed no to slightly higher DM yields than the control, whereas the combined compost urine fertilizer variant achieved around 80% of the DM yield of the mineral‐fertilizer applied reference treatment. The soil's total nitrogen storage is significantly increased in our experiment by the addition of HHFC. The concentration of soluble phosphorus in the soil increases significantly with increased compost applications. However, in the combined compost urine fertilizer variant, sufficient nitrogen supply results in a low level of soluble phosphorus because of high plant biomass production. This trend is reflected in the phosphorus content of plant material. HHFC is considered a good phosphorus fertilizer, which is also confirmed in this experiment. A similar picture emerges for the supply of potassium from HHFC. Although the liquid urine fertilizer (combined with HHFC) does not achieve the DM yield of the mineral reference variant in the early phase of plant growth, it has clear advantages in supplying the crop with nitrogen. This study shows that the recycling of nutrients from human faeces is a potential strategy for conserving finite resources and promoting energy‐efficient agricultural practices in line with the circular economy.

The first section reviews Chandler's argument, touches on the relationship of Chandler's oeuvre to his personal background, and locates 'The Visible Hand' in the context of American historical writing. The second considers how three groups of historians have responded to Chandler's ideas. These groups consist of champions who creatively elaborated on Chandler's intellectual agenda; critics who probed anomalies between Chandler's argument and their own research; and skeptics who rejected Chandler's analysis outright.

description: We develop Entanglement Perturbation Theory (EPT) for infinite Quasi-1D quantum systems. The spin 1/2 Heisenberg chain with ferromagnetic nearest neighbor (NN) and antiferromagnetic next nearest neighbor (NNN) interactions with an easy-plane anisotropy is studied as a prototypical system. The obtained accurate phase diagram is compared with a recent prediction [Phys.Rev.B,81,094430(2010)] that dimer and Neel orders appear alternately as the XXZ anisotropy Delta approaches the isotropic limit Delta=1. The first and second transitions (across dimer, Neel, and dimer phases) are detected with improved accuracy at Delta\approx 0.722 and 0.930. The third transition (from dimer to Neel phases), previously predicted to be at Delta\approx 0.98, is not detected at this Delta in our method, raising the possibility that the second Neel phase is absent.

description: Quark line disconnected matrix elements of an operator, such as the axial current, are difficult to compute on the lattice. The standard method uses a stochastic estimator of the operator, which is generally very noisy. We discuss and develop further our alternative approach using the Feynman-Hellmann theorem which involves only evaluating two-point correlation functions. This is applied to computing the contribution of the quark spin to the nucleon and in particular for the strange quark. In this process we also pay particular attention to the development of an SU(3) flavour breaking expansion for singlet operators.

description: LHCb and Belle II opportunities for model builders, Mainz, Germany, 28 Jan 2019 - 1 Feb 2019
description: New particles in the ~ 1-100 GeV range that couple to gluons and photons are well motivated by frameworks addressing both the hierarchy problem and Dark Matter (e.g. the SUSY R-axion) and by "heavy axion" solutions to the strong CP problem. After reviewing these motivations, I will discuss how vast regions of parameter space are left unexplored by current collider searches. I will then propose a program of new searches for these particles, with particular emphasis on LHCb and Belle-II.

Exploration of the budding yeast kinase Mck1 in cell cycle regulation
Creators: name: McQueen, Jennifer
Publisher: name: University of British Columbia
Year: 2013

description: The study of essential cellular processes such as the regulation of the cell cycle and cellular responses to DNA replication stress in model organisms such as the budding yeast Saccharomyces cerevisiae (S. cerevisiae) benefits our understanding of these processes in human cells. The pathways that govern the response to the DNA replication checkpoint as well as those involved in accurate chromosome segregation are vital to prevent genomic instability, which is a cause of cancer. The yeast cell cycle is governed by one cyclindependent kinase, Cdk1, which controls cell cycle transitions by interacting with specific cyclins during G1, S and M phase. Using a combination of genetic and biochemical techniques, I have discovered that Mck1, a homologue of mammalian glycogen synthase kinase 3 (GSK-3), is a novel negative regulator of Cdk1 activity in budding yeast. My thesis also explores a role for Mck1 during the DNA replication checkpoint. Additionally, my work has contributed to the understanding of the mechanisms utilized to restrain spindle elongation during DNA replication stress. My thesis has three main conclusions; 1) The kinase activity of Mck1 is required to inhibit Clb2-Cdk1 activity post-nuclear division. 2) Mck1 kinase activity is required for survival during chronic exposure to DNA replication stress caused by HU in a process other than checkpoint activation. 3) Overexpression of MCK1 rescues the viability of a kinetochore mutant (spc24-9) that is defective in attachment of chromosomes to kinetochore microtubules. In particular, overexpression of Mck1 restrains the precocious spindle elongation that occurs in spc24-9 strains in response to DNA replication stress. Overall, my thesis demonstrates that the Mck1 kinase contributes to regulation of cell cycle progression in budding yeast. This is important as it demonstrates a conserved function with the mammalian homologue, which has been implicated in several diseases including cancer.

description: New cobalt(II)‐based complexes with [N2O2] coordination formed by two bis‐chelate ligands were synthesized and characterized by a multi‐technique approach. The complexes possess an easy‐axis anisotropy (D<0) and magnetic measurements show a field‐induced slow relaxation of magnetization. The spin‐reversal barriers, i. e., the splitting of the two lowest Kramers doublets (UZFS), have been measured by THz‐EPR spectroscopy, which allows to distinguish the two crystallographically independent species present in one of the complexes. Based on these experimental UZFS energies together with those for related complexes reported in literature, it was possible to establish magneto‐structural correlations. UZFS linearly depends on the elongation parameter ϵT of the (pseudo‐)tetrahedral coordination, which is given by the ratio between the average obtuse and acute angles at the cobalt(II) ion, while UZFS was found to be virtually independent of the twist angle of the chelate planes. With increasing deviation from the orthogonality of the latter, the rhombicity (|E/D|) increases.
JWST reveals widespread CO ice and gas absorption in the Galactic Center cloud G0.253+0.016

description: We report JWST NIRCam observations of G0.253+0.016, the molecular cloud in the Central Molecular Zone known as The Brick, with the F182M, F187N, F212N, F410M, F405N, and F466N filters. We catalog 56,146 stars detected in all 6 filters using the crowdsource package. Stars within and behind The Brick exhibit prodigious absorption in the F466N filter that is produced by a combination of CO ice and gas. In support of this conclusion, and as a general resource, we present models of CO gas and ice and CO$_2$ ice in the F466N, F470N, and F410M filters. Both CO gas and ice may contribute to the observed stellar colors. We show, however, that CO gas does not absorb the Pf$β$ and Hu$ε$ lines in F466N, but that these lines show excess absorption, indicating that CO ice is also present and contributes to observed F466N absorption. The most strongly absorbed stars in F466N are extincted by $\sim$ 2 magnitudes, corresponding to $>$ 80\% flux loss. This high observed absorption requires very high column densities of CO, requiring total CO column that is in tension with standard CO abundance and/or gas-to-dust ratios. There is therefore likely to be a greater CO/H$_2$ ratio (X$_{CO} > 10^{-4}$) and more dust per H$_2$ molecule ($>0.01$) in the Galactic Center than the Galactic disk. Ice and/or gas absorption is observed even in the cloud outskirts, implying that additional caution is needed when interpreting stellar photometry in filters that overlap with ice bands throughout our Galactic Center. The widespread CO absorption in our Galactic Center hints that significant ice absorption is likely present in other galactic centers.

Proposal for Inverting the Quantum Cloning of Photons

Publisher: name: arXiv
Year: 2011
Subjects: subject: Quantum Physics (quant-ph)

description: We propose an experiment where a photon is first cloned by stimulated parametric down-conversion, making many (imperfect) copies, and then the cloning transformation is inverted, regenerating the original photon while destroying the copies. Focusing on the case where the initial photon is entangled with another photon, we study the conditions under which entanglement can be proven in the final state. The proposed experiment would provide a clear demonstration that quantum information is preserved in quantum cloning. It would furthermore allow a definitive experimental proof for micro-macro entanglement in the intermediate multiphoton state, which is still an outstanding challenge. Finally, it might provide a quantum detection technique for small differences in transmission (e.g., in biological samples), whose sensitivity scales better with the number of photons used than a classical transmission measurement.

Verantwortliche aus Wirtschaft und Politik sehen durch fremdenfeindliche Stimmung bereits die Standortattraktivität einiger Regionen gefährdet. Zwei Untersuchungen des IAB zeigen nun, wie sich fremdenfeindliche Einstellungen in Regionen auf die innerdeutsche Arbeitskräftemobilität auswirken, aber auch die Wohnortwahl von Migrant*innen beeinflussen, die neu nach Deutschland kommen, um hier zu arbeiten. Die Redaktion des IAB-Forums hat dazu bei Tanja Buch und Carola Burkert nachgefragt.

description: It has become a cliche to predict that the most fundamental innovations in information technology in the twenty-first century will originate in the garage of some teenage entrepreneur. While this prediction is intuitively appealing, it is almost certainly wrong. No one can predict the future, and forecasting is notoriously inexact. Yet we will have a better chance of avoiding detours, wrong turns, and traffic jams if we have in front of us a road map of where we have been.

description: The SEEBLOCKS.eu workshop “Blockchain - A Transformative Power for a Transatlantic Digital Posterity”, held on 21 March during the SES 2025 Annual Conference in New Orleans, explored emerging standardisation needs in blockchain between the USA and Europe, within a global perspective.

With the EU and US representing nearly one-third of global GDP and sharing the world’s largest bilateral trade relationship, the workshop highlighted the strategic importance of transatlantic collaboration in setting global blockchain standards. Experts from both regions presented key standardisation priorities, followed by a panel discussion on fostering innovation, avoiding fragmented efforts, and paving the way for a unified digital future.

The session attracted stakeholders from public institutions, academia, the ICT sector, blockchain networks, and standardisation bodies.
