description: FAIR-IMPACT acknowledges that effective governance is crucial for developing and maintaining semantic artefacts, enabling a network of interoperable resources across organizations and communities while preventing data silos. To support this, the project has established a dedicated task focused on defining and advancing the concept of 'Semantic Artefact Governance and Management. Through the FAIR-IMPACT Semantic Artefact Governance workshop, we explored a variety of practices across diverse EOSC-related communities. This effort enabled us to generate the final deliverable (D4.1) of FAIR-IMPACT’s T4.1.

This document presents a broadly applicable definition of Semantic Artefact Governance and Management that can be adapted to various contexts. It provides a governance framework that enables initiatives to define their principles, best practices, and standards, ensuring a structured and consistent approach to managing semantic artefacts.

The document demonstrates several approaches to semantic artefact development and management used by different initiatives, highlighting key aspects of the semantic artefact lifecycle. A high-level analysis of organizational structures across multiple initiatives is also included, outlining the domains of activity that need to be considered for effective governance.

Finally, we provide tailored recommendations for three types of initiatives managing semantic artefacts:

Project-based initiatives that oversee individual semantic artefacts, such as application ontologies (e.g., EFO, SAREF), and Linked Open Data sets (e.g., AGROVOC).

Support-based initiatives that facilitate the development and maintenance of interoperable semantic artefacts within communities, such as INRAE Voc, NFDI4Biodiv, and LifeWatch ITA SWG.

Harmonization initiatives that provide principles, guidelines, and infrastructure to standardize semantic artefact management across communities and organizations, such as OBO Foundry, BASF Company, Crop Ontology, and IVOA.

By integrating these elements, this document serves as a comprehensive resource for organizations seeking to implement effective governance and management strategies for semantic artefacts.

description: We present radio continuum observations at frequencies ranging from $\sim$150 to 5000 MHz of the misaligned double-double radio galaxy, DDRG, 3C293 (J1352+3126) using the Giant Metrewave Radio Telescope (GMRT) and the Very Large Array (VLA). The spectra of the outer lobes and the central source are consistent with being straight, indicating spectral ages of $\lapp17-$23 Myr for the outer lobes, and $\lapp$0.1 Myr for the central source. The north-western lobe has a prominent hotspot suggesting that the interruption of jet activity is $\lapp$0.1 Myr, consistent with the age of the inner double. The time scale of interruption of jet activity appears significantly smaller than observed in most other DDRGs which are often associated with giant radio sources. These observations suggest that there is a wide range of time scales of interruption of jet activity in active galaxies.

The targum (1881:Nov. 18)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1881

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: We demonstrate that the Lyman alpha emission in the absorption troughs of a large sample of stacked damped Lyman alpha absorption systems (DLAS) presented by Rahmani et al (2010) is consistent with the spectral profiles and luminosities of a recently detected population of faint Lyman alpha emitters at z ~ 3. This result supports the suggestion that the faint emitters are to be identified with the host galaxies of DLAS at these redshifts.

description: We present new X-ray observations of the A0p stars alpha^2 CVn (log Lx < 26.0 erg/s) and IQ Aur (log Lx = 29.6 erg/s) and find that their X-ray luminosities differ by at least three orders of magnitude. IQ Aur possesses a strong cool plasma component with X-ray emitting regions located well above the stellar surface, but also significant amounts of hot plasma. Further, a large X-ray flare is detected from IQ Aur, implying the presence of magnetic reconnection. Our comparison study of similar stars indicates that the occurrence of X-ray emission generated by magnetically channelled wind shocks (MCWS) strongly depends on stellar properties. X-ray emission is preferably generated by more luminous and massive objects such as IQ Aur. The MCWS scenario can consistently describe the X-ray emission of these A0p stars, assuming that the very strong magnetic confinement of the stellar wind has led to the build up of a rigidly rotating disk around the star, where magnetic reconnection and centrifugal breakout events occur.

title: Interactions of Two-Dimensionally Confined Electrons with an Adjacent Magnetic Monopole
Creators: name: Martin, Johnathan
Publisher: name: University of Kent
Year: 2025

description: An electron in the presence of a magnetic monopole cannot form a bound state to the monopole in three dimensions. All states formed are scattering and follow a geodesic trajectory on the surface of a cone. In this thesis I show that confining the electron to two dimensions and placing the monopole above or below said plane allows for bound states to be formed. Classically, utilising Lagrangian mechanics, these are fully bound never forming scattering states without an influx of energy. Quantum mechanically (Solutions to Schrödinger time independent equation) and semi-classically (Bohr- Sommerfeld quantisation, WKB approximation), these states are quasi-bound with finite lifetimes before turning into a scattering state. The minimum charge that can bind an electron to a magnetic monopole is approximately the same strength as 16 Dirac monopoles. The lifetimes of these scattering states is dependent on the electron's energy eigenvalue, the strength of the magnetic monopole, and the distance the monopole is from the plane. 

Magnetic monopoles can be detected using a SQUID (Superconducting QUantum Interference Device) measuring the quantised jumps in magnetic flux. In this thesis I ask: can they be detected using the Hall effect? With the electrons bound to a plane permeated by the non-uniform magnetic field produced by a magnetic monopole; what will the Hall voltage look like across the plane, and can it be measured? Magnetohydrodynamics is utilised to model the flow of an electron gas by treating it as a fluid that interacts with both magnetic and electrical fields. A single Dirac monopole produces a peak in Hall voltage across the modelled Hall sensor of the order 10−6V. For a monopole found in spin-ice, which is about 1/8000 the magnetic charge of a single Dirac monopole, this voltage is considerably less.

description: Wheelchair maintenance is an important factor in wheelchair mobility. Currently, there is no standardized training resource available to teach wheelchair users about the maintenance or set-up of their manual wheelchairs. Purpose: The purpose of this feasibility research was to assess the feasibility of conducting an experimental study to evaluate the wheelchair maintenance training program. Method: The research program had two main phases. Phase 1 included the development of learning materials, evaluation forms and tests. We performed reliability tests on the 3-cone test and wheelchair maintenance knowledge test and report them in chapter two and three. Phase 2 entailed a feasibility study. In this study, we conducted a wheelchair maintenance workshop to train the mentors (n=5) and then assigned each mentor three mentees (n =15). Each mentor conducted a one-on-one peer-session with each mentee and each mentee completed assigned tests and questionnaires during three assessment visits (baseline, and 2 and 4 weeks after their peer session). Feasibility outcomes were evaluated, and all mentees completed an exit survey at the end of the wheelchair maintenance training program. Results: The 3-cone test and the wheelchair maintenance knowledge test are reliable (ICC >0.9) to use in clinical research. In feasibility study for wheelchair maintenance training, the process outcome (recruitment rate: mentor 71%, mentee 25%), resource outcome (retention rate (>90%), adherence (>90%), fidelity (>80%), completion rate (>90%) and training satisfaction (>90%) and preliminary evaluation outcomes were achieved. Scheduling (management outcome) was challenging and we were not able to meet the goal projected for this outcome, however we were able to complete all the sessions. Conclusion: The 3-cone test and the wheelchair maintenance knowledge test appear to be useful and reliable to be used in the clinical setting. Summary and descriptive results from the feasibility study were sufficient to justify conducting a subsequent randomized controlled trial. We hope to replicate the findings of wheelchair maintenance training by demonstrating the change in mechanical efficacy of wheelchair and the increased knowledge about wheelchair maintenance in the future. This evidence could then be used to support changes in teaching and knowledge improvement in wheelchair maintenance.
Theory of flux cutting and flux transport at the critical current of a type-II superconducting cylindrical wire
Creators: name: Clem, John R.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: I introduce a critical-state theory incorporating both flux cutting and flux transport to calculate the magnetic-field and current-density distributions inside a type-II superconducting cylinder at its critical current in a longitudinal applied magnetic field. The theory is an extension of the elliptic critical-state model introduced by Romero-Salazar and Perez-Rodriguez. The vortex dynamics depend in detail upon two nonlinear effective resistivities for flux cutting (ρ_\parallel) and flux flow (ρ_\perp), and their ratio r = ρ_\parallel/ρ_\perp. When r < 1, the low relative efficiency of flux cutting in reducing the magnitude of the internal magnetic-flux density leads to a paramagnetic longitudinal magnetic moment. As a model for understanding the experimentally observed interrelationship between the critical currents for flux cutting and depinning, I calculate the forces on a helical vortex arc stretched between two pinning centers when the vortex is subjected to a current density of arbitrary angle ϕ. Simultaneous initiation of flux cutting and flux transport occurs at the critical current density J_c(ϕ) that makes the vortex arc unstable.

Dynamics of the dissipative two-state system under ac modulation of bias and coupling energy
Creators: name: Grifoni, Milena
Publisher: name: Universität Regensburg
Year: 1996
Subjects: subject: 500 Naturwissenschaften
subject: 530 Physik

description: We consider a driven dissipative two-state system subject to periodic modulation of both of its two parameters. The exact master equation that governs the dynamics is derived. Closed form analytical solutions are presented within the noninteracting-blip approximation for the stochastic forces, and for the exactly solvable case α = 1 2 of the Ohmic viscosity. We apply these results to a tight-binding particle with zero intrinsic bias. Selection rules are obeyed for arbitrary dissipation. For Ohmic dissipation, the effects of fast asymmetry modulation result in an overall reduction of quantum coherence and in a possible localization. On the contrary, a multiplicative modulation of the tunneling coupling leads to an exponential enhancement of tunneling.

description: We present a study of the Arches cluster based on XMM-Newton observations performed over the past 8 years. Unexpectedly, we find that the X-ray emission associated with the cluster experienced a marked brightening in March/April 2007. We investigate the origin of both the X-ray continuum emission emanating from the star cluster and the flare. To study the time variability of the total X-ray flux, we stacked the PN and MOS data of observations performed within a time interval of a few days leading to the detection of the flaring episode. We then constructed two spectral datasets, one corresponding to the flare interval (March/April 2007) and another to the normal quiescent state of the source. The X-ray light curve of the Arches cluster shows, with high significance (8.6 sigma), a 70% increase in the X-ray emission in the March/April 2007 timeframe followed by a decline over the following year to the pre-flare level; the short-term duration of the flare is constrained to be longer than four days. The temperature and the line-of-sight column density inferred from the flare spectrum do not differ from those measured in the normal activity state of the cluster, suggesting that the flux enhancement is thermal in origin. We attribute the X-ray variability to in situ stellar activity: early-type stars may be responsible for the flare via wind collisions, whereas late-type stars may contribute by means of magnetic reconnection. These two possibilities are discussed.

description: Kepler's laws of planetary motion are acknowledged as highly significant to the construction of universal gravitation. The present study demonstrates different ways to derive the law of equal areas for the Earth by general geometrical and trigonometric methods, which are much simpler than the original derivation depicted by Kepler. The established law of equal area for the Earth was applied to analyze the angular velocity--or the reciprocal of the distance--for the Earth's orbit around the Sun, and can be defined as a periodic function by analyzing the available data, which helps explain the law of ellipses for the Earth.

description: The well-known Bragg-Kleeman rule RCSDA = A dot E0p has become a pioneer work in radiation physics of charged particles and is still a useful tool to estimate the range RCSDA of approximately monoenergetic protons with initial energy E0 in a homogeneous medium. The rule is based on the continuous-slowing-down-approximation (CSDA). It results from a generalized (nonrelativistic) Langevin equation and a modification of the phenomenological friction term. The complete integration of this equation provides information about the residual energy E(z) and dE(z)/dz at each position z (0 <= z <= RCSDA). A relativistic extension of the generalized Langevin equation yields the formula RCSDA = A dot (E0 +E02/2M dot c2)p. The initial energy of therapeutic protons satisfies E0 << 2M dot c2 (M dot c2 = 938.276 MeV), which enables us to consider the relativistic contributions as correction terms. Besides this phenomenological starting-point, a complete integration of the Bethe-Bloch equation (BBE) is developed, which also provides the determination of RCSDA, E(z) and dE(z)/dz and uses only those parameters given by the BBE itself (i.e., without further empirical parameters like modification of friction). The results obtained in the context of the aforementioned methods are compared with Monte-Carlo calculations (GEANT4); this Monte-Carlo code is also used with regard to further topics such as lateral scatter, nuclear interactions, and buildup effects. In the framework of the CSDA, the energy transfer from protons to environmental atomic electrons does not account for local fluctuations.

Practices of sovereignty : negotiated agreements, jurisdiction, and well-being for Heiltsuk Nation
Creators: name: Low, Margaret
Publisher: name: University of British Columbia
Year: 2018

description: Indigenous peoples would strongly deny the Crown ever possessed the power to extinguish their political rights at any point in history. On this view, the Canadian governments do not grant sovereignty to Indigenous peoples. Rather, sovereignty is their inherent right, which flows from ways of knowing and social and political systems that existed long before the arrival of European colonists. I have focused this dissertation on demonstrating the multiple ways in which Heiltsuk Nation practice sovereignty over their territory. Heiltsuk Territory spans 35,553 square kilometres of lands and waters and is located on the central coast of what is now known as British Columbia, Canada. My analysis focuses on practices of Indigenous sovereignty being expressed outside – though supported by – the courts, and specifically in the negotiation and implementation of “reconciliation agreements” between Heiltsuk Nation and the Province of British Columbia and the Government of Canada. Using qualitative data gathered through 2 years of ethnographic fieldwork, my dissertation traces the implications of negotiated agreements between Heiltsuk Nation and the federal and provincial governments, and finds these agreements have enabled new practices of sovereignty, assertions of jurisdiction, new conceptions of Indigenous well-being, and Indigenous-led efforts of reconciliation. Chapter 2 focuses on the implementation of the 2009 Coastal First Nations Reconciliation Protocol (2009 RPA) to explore how, through day-to-day political interactions, this agreement is operating as a mechanism that works to unsettle long-standing assumptions of Crown sovereignty. Chapter 3 documents the “on the ground” tensions arising from overlapping claims of jurisdictional authority in Heiltsuk territory, beginning from the inception of Coastal First Nations – a unique political alliance of several Nations – to the Land and Resource Management process (LRMP) in the early 2000s, through to the government-to-government process developed in response to the increasing legal authority of First Nations at the time. Chapter 4 critically engages colonial conceptions of “well-being” by focusing on the current wellbeing policies being implemented in coastal BC, and specifically in Heiltsuk territory. Chapter 5 illustrates efforts of Heiltsuk Nation to negotiate one of the first “reconciliation framework agreements” between an Indigenous nation and the Government of Canada.

description: We have undertaken the study of the elemental abundances and kinematic properties of a metal-poor sample of candidate thick-disk stars selected from the RAVE spectroscopic survey of bright stars to differentiate among the present scenarios of the formation of the thick disk. In this paper, we report on a sample of 214 red giant branch, 31 red clump/horizontal branch, and 74 main-sequence/sub-giant branch metal-poor stars, which serves to augment our previous sample of only giant stars. We find that the thick disk [alpha/Fe] ratios are enhanced, and have little variation (<0.1 dex), in agreement with our previous study. The augmented sample further allows, for the first time, investigation of the gradients in the metal-poor thick disk. For stars with [Fe/H] < -1.2, the thick disk shows very small gradients, <0.03 +/- 0.02 dex/kpc, in alpha-enhancement, while we find a +0.01 +/- 0.04 dex/kpc radial gradient and a -0.09 +/- 0.05 dex/kpc vertical gradient in iron abundance. In addition, we show that the peak of the distribution of orbital eccentricities for our sample agrees better with models in which the stars that comprise the thick disk were formed primarily in the Galaxy, with direct accretion of stars contributing little. Our results thus disfavor direct accretion of stars from dwarf galaxies into the thick disk as a major contributor to the thick disk population, but cannot discriminate between alternative models for the thick disk, such as those that invoke high-redshift (gas-rich) mergers, heating of a pre-existing thin stellar disk by a minor merger, or efficient radial migration of stars.

description: We identify the L dwarf 2MASS J20261584-2943124 as an unresolved spectral binary, based on low-resolution, near-infrared spectroscopy from IRTF/SpeX. The data reveal a peculiar absorption feature at 1.6 microns, previously noted in the spectra of other very low-mass spectral binaries, which likely arises from overlapping FeH and CH4 absorption bands in the blended light of an L dwarf/T dwarf pair. Spectral template matching analysis indicates component types of L0.5 and T6, with relative brightness Delta H = 4.2+/-0.6. Laser guide star adaptive optics imaging observations with Keck/NIRC2 fail to resolve the source, indicating a maximum separation at the observing epoch of 0.25 arcsec, or a projected separation of 9 AU assuming a distance of 36+/-5 pc. With an age that is likely to be relatively older (>5 Gyr based on the system's large vtan and mass ratio arguments, the relative motion of the potentially "massive" (0.06-0.08 Msun) components of 2MASS J2026-2943 may be detectable through radial velocity variations, like its earlier-type counterpart 2MASS J03202839-0446358 (M8+T5), providing dynamical mass measurements that span the hydrogen burning limit.

description: Stochastic resonance (SR) occurs in nonlinear dynamical systems when the response to a weak coherent input is enhanced by the presence of noise. While classical SR presently is an intensely studied phenomenon, the role of quantum fluctuations has only started to be explored. We study SR in the temperature range where quantum tunneling corrections to the classical rate of activation are relevant. For a particle subject to moderate-to-large friction, we show that the semiclassical SR can be enhanced considerably by quantum fluctuations, as compared to the predictions of a classical analysis.

description: The growth rate of the dynamo instability as a function of the magnetic Reynolds number Rm is investigated by means of numerical simulations for the family of the ABC flows and for 2 different forcing scales. For the ABC flows that are driven at the largest available length scale it is found that as the magnetic Reynolds number is increased: (a) The flow that results first in dynamo is the 2.5D flow for which A=B and C=0 (and all permutations). (b) The second type of flow that results in dynamo is the one for which A=B=2C/5 (and permutations). (c) The most symmetric flow A=B=C is the third type of flow that results in dynamo. (d) As Rm is increased, the A=B=C flow stops being a dynamo and transitions from a local maximum to a third-order saddle point. (e) At larger Rm the A=B=C flow re-establishes its self as a dynamo but remains a saddle point. (f) At the largest examined Rm the growth rate of the 2.5D flows starts to decrease, the A=B=C flow comes close to a local maximum again and the flow A=B=2C/5 (and permutations) results in the fastest dynamo with growth rate $γ~0.12$ at the largest examined Rm. For the ABC flows that are driven at the second largest available length scale it is found that (a) the 2.5D flows A=B, C=0 (and permutations) are again the first flows that result in dynamo with a decreased onset. (b) The most symmetric flow A=B=C is the second type of flow that results in dynamo. It is and remains a local maximum. (c) At larger Rm the flow A=B=2C/5 (and permutations) appears as the third type of flow that results in dynamo. As Rm is increased it becomes the flow with the largest growth rate. The growth rates appear to have some correlation with the Lyaponov exponents but constructive re-folding of the field lines appears equally important in determining the fasted dynamo flow.

description: In both the equations for matter and light wave propagation, the momentum of the electromagnetic fields Pe reflects the relevant em interaction. As a review of some applications of wave propagation properties, an optical experiment which tests the speed of light in moving rarefied gases is described. Moreover, Pe is also the link to the unitary vision of the quantum effects of the Aharonov-Bohm (AB) type, which provide a useful quantum approach for the limit of the photon mass mph. A bench-top experiment based on effects of the AB type that exploit new interferometric techniques, is foreseen to yield the limit mph = 10^-54 g, a value that improves upon the results achieved with other approaches.

Influence of temperature phased anaerobic digestion on stabilization of municipal wastewater sludge

description: Wastewater sludge has the most significant volume among all the constituents that are removed through wastewater treatment, and the annual cost of treating and disposing it accounts for more than half of the overall operation cost of a wastewater treatment plant (WWTP). Among all methods for treating the sludge, anaerobic digestion is the most popular process for its ability to reduce the pathogens and odor potential, save energy by producing methane-rich biogas, as well as reduce the biosolids volume for disposal. Although anaerobic digestion is the most favorable option for the treatment of sludge, it still has some aspects that can be improved. Emerging sludge treatment technologies are currently being studied to reduce the digester volume required and enhance the biogas production in anaerobic digestion. This study investigated the effect of temperature phased anaerobic digestion (TPAD) on treatment of municipal sludge generated by Lulu Island WWTP (BC, Canada) and compared it to conventional single-stage mesophilic anaerobic digestion (AD) currently implemented at the Lulu Island plant. A total number of five lab-scale digesters were operated according to the following scenarios: single-stage mesophilic AD (control), TPAD1 (acid/methane phase temperatures of 55/38°C), TPAD2 (acid/methane phase temperatures of 70/38°C). The systems were operated at three overall sludge retention times (SRTs) including 30, 20, and 15 days. The acid-phase of TPAD systems were able to improve the hydrolysis of sludge significantly and the acid phase of TPAD2 (70°C/2-d SRT) achieved the highest soluble to total chemical oxygen demand (COD), protein, humic acid and sugar ratios. Overall, anaerobic digestion benefited considerably from TPAD in terms of methane yield, pathogen removal and dewatering rate of biosolids. Relative improvements (over control) in solids removal and methane yield increased considerably by gradually decreasing the SRT from 30 to 20 and 15 days. TPAD1 system achieved the maximum methane production and pathogen destruction and it generated Class A biosolids according to Organic Matter Recycling Regulation of British Columbia at all operating SRTs, while the biosolids produced from the other digestion systems (control and TPAD2) could not meet the criteria for Class A and was classified as Class B.

description: We present photometry of the giant extrasolar planet WASP-4b at 3.6 and 4.5 micron taken with the Infrared Array Camera on board the Spitzer Space Telescope as part of Spitzer's extended warm mission. We find secondary eclipse depths of 0.319+/-0.031% and 0.343+/-0.027% for the 3.6 and 4.5 micron bands, respectively and show model emission spectra and pressure-temperature profiles for the planetary atmosphere. These eclipse depths are well fit by model emission spectra with water and other molecules in absorption, similar to those used for TrES-3 and HD 189733b. Depending on our choice of model, these results indicate that this planet has either a weak dayside temperature inversion or no inversion at all. The absence of a strong thermal inversion on this highly irradiated planet is contrary to the idea that highly irradiated planets are expected to have inversions, perhaps due the presence of an unknown absorber in the upper atmosphere. This result might be explained by the modestly enhanced activity level of WASP-4b's G7V host star, which could increase the amount of UV flux received by the planet, therefore reducing the abundance of the unknown stratospheric absorber in the planetary atmosphere as suggested in Knutson et al. (2010). We also find no evidence for an offset in the timing of the secondary eclipse and place a 2 sigma upper limit on |ecos(omega)| of 0.0024, which constrains the range of tidal heating models that could explain this planet's inflated radius.

description: Amorphous oxide semiconductors are gaining interest for logic and memory transistors compatible with low-temperature fabrication. However, their low thermal conductivity and heterogeneous interfaces suggest that their performance may be severely limited by self-heating, especially at higher power and device densities. Here, we investigate the high-field breakdown of ultrathin (~4 nm) amorphous indium tin oxide (ITO) transistors with scanning thermal microscopy (SThM) and multiphysics simulations. The ITO devices break irreversibly at channel temperatures of ~180 °C and ~340 °C on SiO${_2}$ and HfO${_2}$ substrates, respectively, with failure primarily caused by thermally-induced compressive strain near the device contacts. Combining SThM measurements with simulations allows us to estimate a thermal boundary conductance (TBC) of 35 ${\pm}$ 12 MWm${^-}$${^2}$K${^-}$${^1}$ for ITO on SiO${_2}$, and 51 ${\pm}$ 14 MWm${^-}$${^2}$K${^-}$${^1}$ for ITO on HfO${_2}$. The latter also enables significantly higher breakdown power due to better heat dissipation and closer thermal expansion matching. These findings provide insights into the thermo-mechanical limitations of indium-based amorphous oxide transistors, which are important for more reliable and high-performance logic and memory applications.

description: Experiments with cold and ultracold neutrons have reached a level of precision such that problems far beyond the scale of the present Standard Model of particle physics become accessible to experimental investigation. Due to the close links between particle physics and cosmology, these studies also permit a deep look into the very first instances of our universe. First addressed in this article, both in theory and experiment, is the problem of baryogenesis ... The question how baryogenesis could have happened is open to experimental tests, and it turns out that this problem can be curbed by the very stringent limits on an electric dipole moment of the neutron, a quantity that also has deep implications for particle physics. Then we discuss the recent spectacular observation of neutron quantization in the earth's gravitational field and of resonance transitions between such gravitational energy states. These measurements, together with new evaluations of neutron scattering data, set new constraints on deviations from Newton's gravitational law at the picometer scale. Such deviations are predicted in modern theories with extra-dimensions that propose unification of the Planck scale with the scale of the Standard Model ... Another main topic is the weak-interaction parameters in various fields of physics and astrophysics that must all be derived from measured neutron decay data. Up to now, about 10 different neutron decay observables have been measured, much more than needed in the electroweak Standard Model. This allows various precise tests for new physics beyond the Standard Model, competing with or surpassing similar tests at high-energy. The review ends with a discussion of neutron and nuclear data required in the synthesis of the elements during the "first three minutes" and later on in stellar nucleosynthesis.
