description: We consider a one-dimensional commensurate Peierls insulator in the presence of spin-dependent sign-alternating potentials. In a continuum description, the latter supply the fermions with spin-dependent "relativistic" masses $m_{\uparrow,\downarrow}$. The ground-state phase diagram describes three gapped phases: the CDW and SDW-like band insulator phases sandwiched by a "mixed" phase in which the CDW and SDW superstructures coexist with a nonzero spontaneous dimerization (SD). The critical lines separating the massive phases belong to the Ising universality class. The Ising criticality is accompanied by the Kohn anomaly in the renormalized phonon spectrum. We derive a Ginzburg criterion which specifies a narrow region around the critical point where quantum fluctuations play a dominant role, rendering the adiabatic (or mean-field) approximation inapplicable. A full account of quantum effects is achieved in the anti-adiabatic limit where the effective low-energy theory represents a massive version the N=4 Gross-Neveu model. Using Abelian bosonization we demonstrate that the description of the SD phase, including its critical boundaries, is well approximated by a sum of two effective double-frequency sine-Gordon (DSG) models subject to self-consistency conditions that couple the charge and spin sectors. Using the well-known critical properties of the DSG model we obtain the singular parts of the dimerization order parameter and staggered charge and spin susceptibilities near the Ising critical lines. We show that, in the anti-adiabatic limit, on the line $m_{\downarrow} = 0$ there exists of a Berezinskii-Kosterlitz-Thouless critical point separating a Luttinger-liquid gapless phase from the spontaneously dimerized one. We also discuss topological excitations of the model carrying fractional charge and spin. \pacs{71.10.Pm; 71.27.+a; 71.45.Lr; 75.40.Kb}

description: Soil and groundwater salinization, causing vegetative kill areas and water well contamination, are major concerns for farmers not only in Texas but also in many other states across the U.S. In various regions, a combination of natural processes and agricultural activities is primarily responsible for salinization. Moreover, in West Texas, pollution hazards associated with oil exploration and production further complicate the challenge of identifying the sources of soil and groundwater contamination. This study focused on Concho, Runnels, and Tom Green Counties in west-central Texas (see Figure 1) due to the widespread occurrence of soil and groundwater salinization in these areas. Additionally, both natural and man-made sources of salinization could be active in this region. The terrain in this area varies, with hilly terrain present in southern, western, and northern Tom Green County, where remnants of the Edwards Plateau rise to approximately 2,500 feet above sea level. Plains and river valleys dominate most of the remaining area, with the lowest surface elevations (approximately 1,500 feet) found in river valleys to the east. Major drainage systems in the region include the Colorado River in Runnels County, the Concho Rivers in Tom Green and Concho Counties, and several surface-water reservoirs just west of San Angelo. The average annual rainfall in this area is approximately 21 inches, which is nearly one-third of the net lake evaporation.

description: A two-dimensional groundwater flow model was developed along a cross-section through the Palo Duro Basin to understand regional groundwater flow paths and investigate factors influencing underpressuring below the Evaporite aquitard, as well as recharge and discharge mechanisms to and from the Deep-Basin Brine aquifer. Steady-state flow simulations were employed to examine the effects of lithostratigraphy and topography on groundwater flow. Additionally, transient flow simulations were used to describe changes in regional hydrodynamics resulting from various tectonic and geomorphologic processes. The groundwater flow pattern in the Palo Duro Basin is characterized by a shallow groundwater flow system primarily controlled by topography. Deeper flow regimes recharge in the New Mexico area and pass beneath the Pecos River into the deep section of the Palo Duro Basin. The Evaporite aquitard effectively separates the deeper flow regime from the more rapidly circulating shallow aquifer system, although leakage through the aquitard is significant and could contribute up to 27 percent of the water passing through the deep section. Within the Deep-Basin Brine aquifer, groundwater flow patterns are strongly influenced by the spatial distribution of more permeable strata, such as granite-wash deposits, which facilitate drainage of the deep aquifer system more readily than recharge occurs.

description: We explore methods for constructing normal forms of indecomposable quiver representations. The first part of the paper develops homological tools for recursively constructing families of indecomposable representations from indecomposables of smaller dimension vector. This is then specialized to the situation of tree modules, where the existence of a special basis simplifies computations and gives nicer normal forms. Motivated by a conjecture of Kac, we use this to construct cells of indecomposable representations as deformations of tree modules. The second part of the paper develops geometric tools for constructing cells of indecomposable representations from torus actions on moduli spaces of representations. As an application we combine these methods and construct families of indecomposables - grouped into affine spaces - which actually gives a normal form for all indecomposables of certain roots.

description: Most lineaments detected in this study are stream network features. Few lineaments display a one-to-one correspondence with mapped faults or geologic contacts. High values of lineament density demarcate major fault zones. Two regional lineament orientations are significant at the 99-percent confidence level: 325 degrees and 21 degrees. The northwest regional trend is parallel to wellbore elongations at depths down to 8,000 ft in the Jurassic Schuler Formation. The East Texas Basin and the Sabine Uplift have the same significant northwest trend, but the significant northeast lineament orientations for these two subregional structural features are different. The northeast trend in the East Texas Basin is subparallel to that of elongate salt structures there. The northeast trend over the Sabine Uplift may result from stresses generated by upward movement of the uplift. The northwest lineament trend, common to the regional and subregional data sets, is thought to result from gulfward extension in the Gulf Coastal Stress Province where the least principal stress is perpendicular to the coast. Hydraulically generated fractures should propagate perpendicular to the minimum compressive stress and, consequently, perpendicular to the northwest trend of lineaments in this study area. The isopach maps generated in this study show that the Sabine Uplift was part of a large basinal area during the Late Jurassic and Early Cretaceous. The Sabine Uplift does not appear to have been a large Jurassic horst that remained in a structurally high position throughout the Cretaceous and Tertiary, as is commonly shown in the literature. Timing, orientation, and magnitude of Sabine arching indicate that the Sabine Uplift may have been produced by northeast-directed tectonic events related to orogenic activity in the southern North American Cordillera and the Sierra Madre Oriental in Mexico.
Microscopic Theory of Ultrafast Out-of-Equilibrium Dynamics in Magnetic Insulators. Unraveling the Magnon-Phonon Coupling

description: The interaction between lattice and spins is at the heart of an extremely intriguing ultrafast dynamics in magnetic materials. In this work we formulate a general non-equilibrium theory that disentangles the complex interplay between them in a THz laser-excited antiferromagnetic insulator. The theory provides a quantitative description of the transient energy flow between the spin and lattice sub-systems, subject to magnon-phonon and phonon-phonon scatterings, giving rise to finite life-times of the quasiparticles and to the equilibration time of the system. We predict a novel kind of scattering process where two magnons of opposite polarizations decay into a phonon, previously omitted in the literature. The theory is combined with first-principle calculations and then applied to simulate a realistic dynamics of NiO. The main relaxation channels and hot spots in the reciprocal space, giving the strongest contribution to the energy transfer between phonons and magnons are identified. The diverse interaction strengths lead to distinct coupled dynamics of the lattice and spin systems and subsequently to different equilibration timescales.

description: Understanding the origins of spin lifetimes in hybrid quantum systems is a matter of current importance in several areas of quantum information and sensing. Methods that spectrally map spin relaxation processes provide insight into their origin and can motivate methods to mitigate them. In this paper, using a combination of hyperpolarization and precision field cycling over a wide range (1mT-7T), we map frequency dependent relaxation in a prototypical hybrid system of 13C nuclear spins in diamond coupled to Nitrogen Vacancy centers. Nuclear hyperpolarization through the optically pumped NV electrons allows signal time savings for the measurements exceeding million-fold over conventional methods. We observe that 13C lifetimes show a dramatic field dependence, growing rapidly with field up to 100mT and saturating thereafter. Through a systematic study with increasing substitutional electron (P1 center) concentration as well as 13C enrichment levels, we identify the operational relaxation channels for the nuclei in different field regimes. In particular, we demonstrate the dominant role played by the 13C nuclei coupling to the interacting P1 electronic spin bath. These results pave the way for quantum control techniques for dissipation engineering to boost spin lifetimes in diamond, with applications ranging from engineered quantum memories to hyperpolarized 13C imaging.

Η παρούσα εργασία περιλαμβάνει μια βιβλιογραφική ανασκόπηση για εφαρμογή της ΑΤΥ σε όλες τις ευρωπαϊκές χώρες. Επιπλέον, πραγματοποιήθηκε ανάλυση της φαρμακευτικής πολιτικής και του πλαισίου ΑΤΥ της Ελλάδας, ενώ με τη μέθοδο ανάλυσης SWOT εντοπίστηκαν δυνατά σημεία, αδυναμίες, ευκαιρίες και απειλές. Στην Ελλάδα φαίνεται ότι υπάρχουν σημαντικές βελτιώσεις στο πλαίσιο της ΑΤΥ, ωστόσο υπάρχει χώρος για περαιτέρω βελτίωση σε ορισμένους τομείς . Δεδομένων των αλλαγών που αναμένονται στην ΑΤΥ σε Ευρωπαϊκό επίπεδο τα επόμενα χρόνια, η Ελλάδα ενθαρρύνεται να προετοιμαστεί για αυτές. Με σταθερή πολιτική υποστήριξη, διάθεση πόρων και προσαρμογές στο υφιστάμενο νομοθετικό πλαίσιο, το πλαίσιο ΑΤΥ δύναται να εξελιχθεί περαιτέρω, αξιοποιώντας νέες ευκαιρίες στον ορίζοντα.

description: The phase diagram of the spin-3/2 Blume-Capel model in two dimensions is explored by conventional finite-size scaling, conformal invariance and Monte Carlo simulations. The model in its $τ$-continuum Hamiltonian version is also considered and compared with others spin-3/2 quantum chains. Our results indicate that differently from the standard spin-1 Blume-Capel model there is no multicritical point along the order-disorder transition line. This is in qualitative agreement with mean field prediction but in disagreement with previous approximate renormalization group calculations. We also presented new results for the spin-1 Blume-Capel model.

description: Schwinger's quantization scheme is extended in order to solve the problem of the formulation of quantum mechanics on a space with a group structure. The importance of Killing vectors in a quantization scheme is showed. Usage of these vectors provides algebraic properties of operators to be consistent with the geometrical structure of a manifold. The procedure of the definition of the quantum Lagrangian of a free particle and the norm of velocity (momentum) operators is given. These constructions are invariant under a general coordinate transformation. The unified procedure for constructing the quantum theory on a space with a group structure is developed. Using it quantum mechanics on a Riemannian manifold with a simply transitive group acting on it is investigated.

description: Aims. Moreno-Insertis et al. (2018) recently discovered two types of flux emergence in their numerical simulations: magnetic loops and magnetic sheet emergence. Whereas magnetic loop emergence has been documented well in the last years, by utilising high-resolution full Stokes data from ground-based telescopes as well as satellites, magnetic sheet emergence is still an understudied process. We report here on the first clear observational evidence of a magnetic sheet emergence and characterise its development. Methods. Full Stokes spectra from the Hinode spectropolarimeter were inverted with the SIR code to obtain solar atmospheric parameters such as temperature, line-of-sight velocities and full magnetic field vector information. Results. We analyse a magnetic flux emergence event observed in the quiet-sun internetwork. After a large scale appearance of linear polarisation, a magnetic sheet with horizontal magnetic flux density of up to 194 Mx/cm$^{2}$ hovers in the low photosphere spanning a region of 2 to 3 arcsec. The magnetic field azimuth obtained through Stokes inversions clearly shows an organised structure of transversal magnetic flux density emerging. The granule below the magnetic flux-sheet tears the structure apart leaving the emerged flux to form several magnetic loops at the edges of the granule. Conclusions. A large amount of flux with strong horizontal magnetic fields surfaces through the interplay of buried magnetic flux and convective motions. The magnetic flux emerges within 10 minutes and we find a longitudinal magnetic flux at the foot points of the order of $\sim$$10^{18}$ Mx. This is one to two orders of magnitude larger than what has been reported for small-scale magnetic loops. The convective flows feed the newly emerged flux into the pre-existing magnetic population on a granular scale.

description: Foundations of algebrodynamics based on earlier proposed equations of biquaternionic holomorphy are briefly expounded. Free Maxwell and Yang-Mills Eqs. are satisfied identically on the solutions of primary system which is also related to the Eqs. of shear-free null congruences (SFC), and through them - to the Einstein-Maxwell electrovacuum system. Kerr theorem for SFC reduces the basic system to one algebraic equation, so that with each solution of the latter some (singular) solution of vacuum Eqs. may be associated. We present some exact solutions of basic algebraic and of related field Eqs. with compact structure of singularities of electromagnetic field, in particular having the form of figure "8" curve. Fundamental solution to primary system is analogous to the metric and fields of the Kerr-Newman solution. In addition, in the framework of algebraic dynamics the value of electric charge for this solution is strictly fixed in magnitude and may be set equal to the elementary charge.

description: In this paper, we consider a broadcasting process in which information is propagated from a given root node on a noisy tree network, and answer the question that whether the symbols at the nth level of the tree contain non-vanishing information of the root as n goes to infinity. Although the reconstruction problem on the tree has been studied in numerous contexts including information theory, mathematical genetics and statistical physics, the existing literatures with rigorous reconstruction thresholds established are very limited. In the remarkable work of Borgs, Chayes, Mossel and Roch (The Kesten-Stigum reconstruction bound is tight for roughly symmetric binary channels), the exact threshold for the reconstruction problem for a binary asymmetric channel on the d-ary tree is establish, provided that the asymmetry is sufficiently small, which is the first exact reconstruction threshold obtained in roughly a decade. In this paper, by means of refined analyses of moment recursion on a weighted version of the magnetization, and concentration investigations, we rigorously give a complete answer to the question of how small it needs to be to establish the tightness of the reconstruction threshold and further determine its asymptotics of large degrees.

description: Tunneling conductance spectra of normal metal/insulator/triplet superconductor junctions are investigated theoretically. As triplet paring states we select several types of symmetries that are promising candidates for the superconducting states in UPt$_{3}$ and in Sr$_{2}$RuO$_{4}$. The calculated conductance spectra are sensitive to the orientation of the junction which reflects the anisotropy of the pairing states. They show either zero-bias conductance peaks or gap-like structures depending on the orientation of the junctions. The existence of a residual density of states, peculiar to nonunitary states, is shown to have a significant influence on the properties of the conductance spectra. Present results serve as a guidefor the experimental determination of the symmetry of the pair potentials in UPt$_{3}$ and Sr$_{2}$RuO$_{4}$.

Creators: name: Caran, S. Christopher

Year: 1985
Subjects: subject: climate change
subject: paleoclimate
subject: Texas Panhandle

description: Among the many factors to be considered in planning a high-level nuclear waste repository in northwestern Texas are future climatic conditions and their role in affecting environmental change. In future millennia, the regional climate will almost certainly undergo episodic variations comparable to those inferred from the paleoclimatic record of the late Quaternary Period. In addition, local and perhaps global weather patterns may change in ways not previously sustained, as a consequence of inadvertent and possibly deliberate human activities. If the scope and duration of these natural and induced climatic changes were significant, they would appreciably influence geomorphic and geohydrologic processes in the Texas Panhandle.
Fatigue bei Multipler Sklerose unter besonderer Berücksichtigung komorbider schlafmedizinischer Erkrankungen

description: Schlafmedizinische Erkrankungen sind häufig bei MS-Patienten, welche unter einer MS-Fatigue leiden. Es existiert ein signifikanter Zusammenhang zwischen erhöhten Werten in der Modified Fatigue Impact Scale (MFIS) und der Fatigue Severity Scale (FSS) und dem Vorliegen einer schlafmedizinischen Erkrankung. In zukünftigen MS-Fatigue-Studien sollten schlafmedizinische Erkrankungen als wichtiger Störfaktor regelhaft untersucht und berücksichtigt werden. Die Behandlung einer komorbiden schlafmedizinischen Erkrankung scheint die MS-Fatigue zu bessern. Die Verbesserung der Lebensqualität und die Erhaltung der Erwerbsfähigkeit stellen weitere Gründe dar, welche für die konsequente Behandlung einer komorbiden schlafmedizinischen Erkrankung sprechen. Schlafmedizinische Untersuchungen wie die Polysomnographie können zudem möglicherweise neue Erkenntnisse über eine Beeinträchtigung des motorischen Systems bei MS-Patienten liefern, da ein erhöhter Index an periodischen Beinbewegungen im REM-Schlaf einen Risikofaktor für einen erhöhten Grad der Behinderung darstellt. Ambulante Polysomnographien, welche bei den Patienten zu Hause durchgeführt werden, weisen nur einen geringen Habituationseffekt (First-Night-Effect) auf.

subject: Education policy

description: Nigeria’s Universal Basic Education Act, 2004 (UBE Act) states that basic education should be free, compulsory and universal. (UBE Act, 2004). However, its implementation in Adamawa State has been significantly disrupted by the Boko Haram insurgency, which has caused mass internal displacement. The return and resettlement of previously displaced communities provide opportunities to implement the Act fully, and in doing so to improve access to and the quality and continuity of education in the State. The Education Research in Conflict and Protracted Crisis (ERICC) programme considers existing factors influencing educational provision at policy and local levels in areas affected by conflict and crisis. The programme aims to guide interventions that will improve policy-practice coherence, which will lead to greater access to and improved quality and continuity of education in these contexts. Nigeria is one of six countries involved in the research programme. The focus here is on the factors that enable or hinder the implementation of the UBE Act in Adamawa State.
There has been very limited research to date on the provision of basic education in this context of return and resettlement, which limits the opportunities for policy-makers and others to make evidence-informed decisions on basic education. ERICC seeks to fill this research and knowledge gap.This policy brief summarises the findings, implications and recommendations of research conducted in Madagali Local Government Area (LGA) in northern Adamawa State. A comprehensive evidence review was conducted to identify evidence gaps (Mishra et al., 2023), complemented by extensive consultations with federal and local stakeholders in Nigeria (Akogun et al., 2023) to understand the educational context in Adamawa and draw out recommendations. Further research will inform the design of interventions to improve the provision of basic education in the State.

description: This project aimed to complete the calculation of lignite resources in Texas according to USGS Circular 891 and begin providing petrographic data on Texas lignite. To date, no resource calculations have been done; however, considerable petrographic data have been collected. There is no progress to report on the calculation of resources in the East Texas Jackson/Yegua trend because we are awaiting completion of data entry and digitization by the USGS. In July 1984, resource and lithologic data and geographical locations for data points in the East Texas Jackson/Yegua trend were submitted to the USGS, who is responsible for entering these data into the PR1ME computer database (TXSTRAT) and digitizing the geographical locations. At present, data have been entered for 23 of the 40 quadrangles submitted to the USGS (see attached figure). This represents 45 percent of the approximately 6,137 points submitted. Twenty-one of the 40 quadrangles have been digitized, representing 53 percent of the approximately 1,102 geographic locations submitted. Upon completion of data entry and digitization, we can begin the calculation of resources as outlined in our October 1985 proposal.
Single-shot wideband active microrheology of viscoelastic fluids using pulse-scanned optical tweezers

description: We present a fast active microrheology technique exploring the phase response of a microscopic probe particle trapped in a linear viscoelastic fluid using optical tweezers under an external perturbation. Thus, we experimentally determine the cumulative response of the probe to an entire repertoire of sinusoidal excitations simultaneously by applying a spatial square pulse as an excitation to the trapped probe. The square pulse naturally contains the fundamental sinusoidal frequency component and higher odd harmonics, so that we measure the phase response of the probe over a very wide frequency band in a single shot. We then determine the responses to individual harmonics using a lock-in algorithm, and compare the phase shifts to those obtained theoretically by solving the equation of motion of the probe particle confined in a harmonic potential in the fluid in the presence of a sinusoidal perturbation. We go on to relate the phase response of the probe to the complex shear modulus $G^{*}(ω)$, and proceed to verify our technique in a mixture of polyacrylamide and water, which we compare with known values in literature and obtain very good agreement. Our method ensures that any drifts in time are almost entirely ruled out from the data, with the added advantage of high speed and ease of use.
