description: Confronting climate change with a delayed onset of the Monsoon season and an increase in anthropogenic aerosol concentrations is the new normal. In water-scarce regions such as New Mexico, that rely on rainfall during the summer season, there is a strong concern on how water resources will be affected by future climate change enhanced due to increase in greenhouse gases. Paleoclimate studies offer a lens through which to better prepare for future climate scenarios by investigating trends in pre-instrumental paleoclimate data. However, a thorough understanding of how climate variables are reflected in the geochemistry of paleoclimate data is required. Further, sub-annually resolved paleoclimate data are essential to delineate seasonal variability. The geochemical variability of stalagmites harvested from near cave entrances preserve sub-annual climate variability. Further, the geochemical variability from 20th century sub-annually stalagmite records can serve as important links between cave-monitoring and longer stalagmite records. Through monitoring a shallow cave in New Mexico (Sitting Bull Falls Cave), we document seasonal variability in Mg concertation of modern cave calcite to reflect variability in surface-air temperature. We next investigate the controls on the geochemical variability of two 20th century growing stalagmites retrieved from the same cave. To retrieve an age model, we develop a depth-to-age peak counting algorithm using the temperature-dependent variation of calcite Mg concentrations. We next qualitatively compare the sub-annually resolved time series against instrumental data of rainfall, wind speed, and aerosol deposition to ascertain seasonal trends. We find that Fe concentrations increase during the Monsoon Season (July-September). Zn and Cu concentrations increase during the pre-Monsoon season, which we infer to record aerosol deposition. Finally, we use XRCT scans to reconstruct the internal growth morphology of a new core in Sitting Bull Falls cave with the aim to retrieve a record that pre-dates the instrumental record. The result from this research demonstrates that increase in transition metal concentrations reflect season of recharge (Fe) and aerosol deposition (Zn). This relationship between proxy and climate variable should be consistent in stalagmites from other regions. And stalagmites that pre-date the instrumental can potentially reconstruct the variability in groundwater recharge and delineate between natural and anthropogenic deposition

description: Introduction: Hypospadias is a continuum of different variants, and megameatus intact prepuce (MIP) is an uncommon form of glandular hypospadias seen in around 3-6% of hypospadias. Surgical options in the management of megameatus intact prepuce depends on multiple scenarios and is multifactorial, hence the different surgical options with different outcomes. The aim of this article is to review the surgical management options of these rare variant of hypospadias called megameatus intact prepuce. Materials and Methods: We look for information on the following platformsGoogle Scholar, PubMed Central (PMC), PubMed, AJOL and EMBASE for articles on Megameatus intact prepuce, and the last search was on 14th May, 2021, using the keywords surgical management options of megameatus intact prepuce and the relevant articles were reviewed to extract the surgical options of managing megameatus intact prepuce variant of hypospadias from the experts. Results: The surgical management of MIP is aimed at restoring function and cosmesis, and several surgical techniques, including the glanular approximation procedure (GAP), the pyramid procedure, the cutaneous advancement procedure, the tubularised incised plate (TIP), the tubularised Urethral Plate Urethroplasty (TUPU), the Mathieu technique, and the subcutaneous frenulum flap with many modifications, have been described. Discussion: MIP is rare and was first described by Juskiewenski and co in 1983, several researchers have reported on various surgical treatment options with varying results,, Elbatarny et al observed GAP in seventeen patients with MIP over a five-year span in 2011, with an excellent outcome in 14 patients and a subjective score of 1 in two patients, with one patient expressing disappointment with the outcome. M. Sanal et al. identified an excellent outcome in seven cases with GAP. Conclusion: The surgical management options for megameatus intact prepuce are many, with varying modifications and results, necessitating a urologist's knowledge of as many procedures as possible in order to achieve a desired aim in treating this group of patients with an unusual anomaly.

description: We derive a simple formula for the second-order subdifferential of the maximum of coordinates which allows us to construct this set immediately from its argument and the direction to which it is applied. This formula can be combined with a chain rule recently proved by Mordukhovich and Rockafellar [9] in order to derive a similarly simple formula for the extended partial second-order subdifferential of finite maxima of smooth functions. Analogous formulae can be derived immediately for the full and conventional partial second-order subdifferentials.

description: We consider translation-invariant interacting particle systems on the lattice with finite local state space admitting at least one Gibbs measure as a time-stationary measure. The dynamics can be irreversible but should satisfy some mild non-degeneracy conditions. We prove that weak limit points of any trajectory of translation-invariant measures, satisfying a non-nullness condition, are Gibbs states for the same specification as the time-stationary measure. This is done under the additional assumption that zero entropy loss of the limiting measure w.r.t. the time-stationary measure implies that they are Gibbs measures for the same specification.We also give an alternate version of the last condition such that the non-nullness requirement can be dropped. For dynamics admitting a reversible Gibbs measure the alternative condition can be verified, which yields the attractor property for such dynamics. This generalizes convergence results using relative entropy techniques to a large class of dynamics including irreversible and non-ergodic ones. We use this to show synchronization for the rotation dynamics exhibited in citeJaKu12 possibly at low temperature, and possibly non-reversible. We assume the additional regularity properties on the dynamics: 1 There is at least one stationary measure which is a Gibbs measure. 2 Zero loss of relative entropy density under dynamics implies the Gibbs property.

description: We introduce a new translation from linear temporal logic (LTL) to deterministic Emerson-Lei automata, which are omega-automata with a Muller acceptance condition symbolically expressed as a Boolean formula. The richer acceptance condition structure allows the shift of complexity from the state space to the acceptance condition. Conceptually the construction is an enhanced product construction that exploits knowledge of its components to reduce the number of states. We identify two fragments of LTL, for which one can easily construct deterministic automata and show how knowledge of these components can reduce the number of states. We extend this idea to a general LTL framework, where we can use arbitrary LTL to deterministic automata translators for parts of formulas outside the mentioned fragments. Further, we show succinctness of the translation compared to existing construction. The construction is implemented in the tool Delag, which we evaluate on several benchmarks of LTL formulas and probabilistic model checking case studies.

Here A is the center of mass of v and l[subscript A] is a linear function with gradient equal to A everywhere. We show also that in the scalar case m = 1 any probability measure with finite action on L has this property. We provide elementary proofs of these results."

description: We present here a Hofstadter's butterfly spectrum for the magic angle twisted bilayer graphene obtained using an ab initio based multi-million atom tight-binding model. We incorporate a hexagonal boron nitride substrate and out-of-plane atomic relaxation. The effects of a magnetic field are introduced via the Peierls modification of the long-range tight-binding matrix elements and the Zeeman spin splitting effects. A nanoribbon geometry is studied, and the quantum size effects for the sample widths up to 1 $μ$m are analyzed both for a large energy window and for the flatband around the Fermi level. For sufficiently wide ribbons, where the role of the finite geometry is minimized, we obtain and plot the Hofstadter spectrum and identify the in-gap Chern numbers by counting the total number of chiral edge states crossing these gaps. Subsequently, we examine the Wannier diagrams to identify the insulating states at charge neutrality. We establish the presence of three types of electronic states: moiré, mixed, and conventional. These states describe both the bulk Landau levels and the edge states crossing gaps in the spectrum. The evolution of the bulk moiré flatband wavefunctions in the magnetic field is investigated, predicting a decay of the electronic density from the moiré centers as the magnetic flux increases. Furthermore, the spatial properties of the three types of edge states are studied, illustrating the evolution of their localization as a function of the nanoribbon momentum.

description: Angular momentum dependence of nuclear level densities at finite temperatures are investigated in the static path approximation(SPA) to the partition function using a cranked quadrupole interaction Hamiltonian in the following three schemes: (i) cranking about x-axis, (ii) cranking about z-axis and (iii) cranking about z-axis but correcting for the orientation fluctuation of the axis. Performing numerical computations for an $sd$ and a $pf$ shell nucleus, we find that the x-axis cranking results are satisfactory for reasonably heavy nuclei and this offers a computationally faster method to include the angular momentum dependence at high temperatures in the SPA approach. It also appears that at high spins inclusion of orientation fluctuation correction would be important.

description: Silicate weathering is a fundamental process that sculpts landscapes, provides nutrients for organisms, underpins life-sustaining biogeochemical cycles on Earth, and keeps Earth from entering a runaway greenhouse state. This process is influenced by the geologic and environmental conditions at the Earth's surface, therefore uniting many traditional geoscience subdisciplines and being an area of active research for nearly a century. It has been studied through observations of drainage catchments on continents, where most silicate weathering on Earth happens today. The geologic record also served as an important archive of this process, invariably recording the conditions and processes occurring at the Earth's surface in the past and allowing for observations on timescales that studies of modern environments do not permit. Despite advancements in the process-based understanding of silicate weathering, considerable debate remains regarding its primary drivers, the relevance of silicate weathering in the evolution of Earth's climate, and the degree with which known modulators of silicate weathering can be constrained independently of one another. The central focus of this dissertation is to expand upon the utility of lithium (Li) isotopes: a burgeoning isotope system that, when measured in geologic material, allows for a quantitative assessment of silicate weathering over a range of timescales. The dissertation is composed of three case studies which test the viability of Li isotopes in discerning the controls of silicate weathering, both in past and present environments. In turn, these studies help identify controls of silicate weathering in different Earth surface environments. The outcome of these studies are conceptual or mechanistic models for silicate weathering that either i) provide constraints for its controls or ii) yield a template with which to probe it with Li isotopes and other measurements

description: Many Heusler compounds possess magnetic properties well-suited for applications as spintronic materials. The pseudo-binary Mn$_{0.5}$Fe$_{0.5}$Ru$_2$Sn, formed as a solid solution of two full Heuslers, has recently been shown to exhibit exchange hardening suggestive of two magnetic phases, despite existing as a \textit{single} chemical phase. We have performed a first-principles study of the chemical and magnetic degrees of freedom in the Mn$_{1-x}$Fe$_{x}$Ru$_2$Sn pseudo-binary to determine the origin of the unique magnetic behavior responsible for exchange hardening within a single phase. We find a transition from antiferromagnetic (AFM) to ferromagnetic (FM) behavior upon replacement of Mn with Fe, consistent with experimental results. The lowest energy orderings in Mn$_{1-x}$Fe$_{x}$Ru$_2$Sn consist of chemically- and magnetically-uniform (111) planes, with Fe-rich regions preferring FM ordering and Mn-rich regions preferring AFM ordering, independent of the overall composition. Analysis of the electronic structure suggests that the magnetic behavior of this alloy arises from a competition between AFM-favoring Sn-mediated superexchange and FM-favoring RKKY exchange mediated by spin-polarized conduction electrons. Changes in valency upon replacement of Mn with Fe shifts the balance from superexchange-dominated interactions to RKKY-dominated interactions.

description: The algebraic spin liquid is a long-sought-after phase of matter characterized by the absence of quasiparticle excitations, a low-energy description in terms of emergent Dirac fermions and gauge fields interacting according to (2+1)D quantum electrodynamics (QED3), and power-law correlations with universal exponents. The prototypical algebraic spin liquid is the Affleck-Marston $\pi$-flux phase, originally proposed as a possible ground state of the spin-1/2 Heisenberg model on the 2D square lattice. While the latter model is now known to order antiferromagnetically at zero temperature, recent sign-problem-free quantum Monte Carlo simulations of spin-1/2 fermions coupled to a compact U(1) gauge field on the square lattice have shown that quantum fluctuations can destroy N\'eel order and drive a direct quantum phase transition to the $\pi$-flux phase. We show this transition is in the universality class of the chiral Heisenberg QED3-Gross-Neveu-Yukawa model with a single SU(2) doublet of four-component Dirac fermions (i.e., $N_f=1$), pointing out important differences with the corresponding putative transition on the kagome lattice. Using an $\epsilon$ expansion below four spacetime dimensions to four-loop order, and a large-$N_f$ expansion up to second order, we show the transition is continuous and compute various thermodynamic and susceptibility critical exponents at this transition, setting the stage for future numerical determinations of these quantities. As a byproduct of our analysis, we also obtain charge-density-wave and valence-bond-solid susceptibility exponents at the semimetal-antiferromagnetic insulator transition in graphene.

description: Motivated by recent experiments, which give strong evidence for an excitonic insulating phase in $\rm TmSe_{0.45}Te_{0.55}$, we developed a scheme to quantitatively construct, for generic two-band models, the phase diagram of an excitonic insulator. As a first application of our approach, we calculated the phase diagram for an effective mass two-band model with long-range Coulomb interaction. The shielded potential approximation is used to derive a generalized gap equation controlling for positive (negative) energy gaps the transition from a semi-conducting (semi-metallic) phase to an insulating phase. Numerical results,obtained within the quasi-static approximation, show a steeple-like phase diagram in contrast to long-standing expectations.

description: The radiogenic accumulation and thermally activated diffusive loss of ⁴He from accessory minerals, such as apatite and zircon, has been widely used to recover low-temperature thermal histories and relate them to upper-crustal and near-surface geological processes, such as tectonic exhumation or long-term landscape evolution. A single (U-Th)/He total gas age can be the result of an infinite number of thermal histories. Thus, thermal history reconstruction generally requires either analysis of multiple sample arrays, multiple thermochronometers, or leveraging potential kinetic differences between grains within a single sample. In contrast, it has been demonstrated that the spatial distribution of ⁴He found in a single grain is a function of the sample’s thermal history experienced and the intra-grain parent nuclide (U and Th) distribution. By normalizing ⁴He against a uniform concentration of proton-irradiation induced spallogenic ³He, intragrain ⁴He/³He concentration profiles can be determined by fractional loss step-heating experiments. While ⁴He/³He thermochronometry has been successfully applied to apatite, the applicability of zircon has been hampered by more common and complex intra-grain U and Th zonation that must be addressed. This study explored zircon ⁴He/³He thermochronometry by systematically investigating the effects of different laser-heating protocols and measuring parent nuclide zonation both by one-dimensional (depth-profiling) and two-dimensional LA-ICP-MS parent nuclide zonation mapping. The integration of both ⁴He/³He profiles from fractional loss experiments and parent nuclide zonation determinations allowed for the evaluation of thermal histories in comparison with results from numerical forward modeling. The developed methodology was applied to single-crystal zircon grains from rapidly cooled volcanic (Fish Canyon Tuff), drilled crustal (KTB), and fault-exhumed crustal (Wassuk Range) rocks with independently determined thermal histories to test the robustness and reliability. The results illustrate the potential of zircon ⁴He/³He thermochronometry, as well as address major analytical pitfalls and the importance of characterizing parent nuclide zonation
Early Starbursts and Magnetic Field Generation in Galaxy Clusters

Publisher: name: arXiv
Year: 2000

description: We propose a mechanism for the early generation of the mean Intracluster magnetic field in terms of magnetized galactic winds. These winds are the result of starburst phases of the cluster galaxies, assumed to produce the predominant population of early type galaxies in mergers of gas-rich progenitors. After further cluster contraction typical field strengths are $10^{-7}$ Gauss. This estimate may increase to the level of $10^{-6}$ Gauss if more extreme galactic parameters, and subsequent shear amplification of the field are considered. The topology of the field is one of almost unconnected Wind Bubbles with Parker-type spiral field configurations over scales of the distance between galaxies. Further cluster accretion, that continues chaotically in space and time up to the present, will perturb these "large-scale" mean fields on smaller or at best comparable spatial scales. The small scale fields in the resulting turbulent fluctuation spectrum should be able to confine relativistic particles over times longer than the age of the Universe. The nonthermal particle content of galaxy clusters should therefore also have a "cosmological" hadronic component generated during the early starburst phase of the member galaxies. Already by itself it implies a nonthermal energy fraction of about 10 percent for the Intracluster gas which should then be detectable by future gamma-ray telescopes.

description: As a surrogate for computationally intensive meso-scale simulation of woven composites, this article presents Recurrent Neural Network (RNN) models. Leveraging the power of transfer learning, the initialization challenges and sparse data issues inherent in cyclic shear strain loads are addressed in the RNN models. A mean-field model generates a comprehensive data set representing elasto-plastic behavior. In simulations, arbitrary six-dimensional strain histories are used to predict stresses under random walking as the source task and cyclic loading conditions as the target task. Incorporating sub-scale properties enhances RNN versatility. In order to achieve accurate predictions, the model uses a grid search method to tune network architecture and hyper-parameter configurations. The results of this study demonstrate that transfer learning can be used to effectively adapt the RNN to varying strain conditions, which establishes its potential as a useful tool for modeling path-dependent responses in woven composites.

Linear-time Temporal Logic with Event Freezing Functions

Year: 2017
Subjects: subject: Logic in Computer Science (cs.LO)

description: Formal properties represent a cornerstone of the system-correctness proofs based on formal verification techniques such as model checking. Formalizing requirements into temporal properties may be very complex and error prone, due not only to the ambiguity of the textual requirements but also to the complexity of the formal language. Finding a property specification language that balances simplicity, expressiveness, and tool support remains an open problem in many real-world contexts. In this paper, we propose a new temporal logic, which extends First-Order Linear-time Temporal Logic with Past adding two operators "at next" and "at last", which take in input a term and a formula and represent the value of the term at the next state in the future or last state in the past in which the formula holds. We consider different models of time (including discrete, dense, and super-dense time) and Satisfiability Modulo Theories (SMT) of the first-order formulas. The "at next" and "at last" functions can be seen as a generalization of Event-Clock operators and can encode some Metric Temporal operators also with counting. They are useful to formalize properties of component-based models because they allow to express constraints on the data exchanged with messages at different instants of time. We provide a simple encoding into equisatisfiable formulas without the extra functional symbols. We implement a prototype tool support based on SMT-based model checking.

description: We revisit the construction of signature classes in C*-algebra K-theory, and develop a variation that allows us to prove equality of signature classes in some situations involving homotopy equivalences of noncompact manifolds that are only defined outside of a compact set. As an application, we prove a counterpart for signature classes of a codimension two vanishing theorem for the index of the Dirac operator on spin manifolds (the latter is due to Hanke, Pape and Schick, and is a development of well-known work of Gromov and Lawson).

description: In a Luttinger liquid phase of one-dimensional molecular matter the strength of zero-point motion can be characterized by dimensionless De Boer's number quantifying the interplay of quantum fluctuations and two-body interactions. Selecting the latter in the Morse form we show that dissociation of the Luttinger liquid is a process initiated at the system edge. The latter becomes unstable against quantum fluctuations at a value of De Boer's number which is smaller than that of the bulk instability which parallels the classical phenomenon of surface melting.

description: We construct colliding plane wave solutions in higher dimensional gravity theory with dilaton and higher form flux, which appears naturally in the low energy theory of string theory. Especially, the role of the junction condition in constructing the solutions is emphasized. Our results not only include the previously known CPW solutions, but also provide a wide class of new solutions that is not known in the literature before. We find that late time curvature singularity is always developed for the solutions we obtained in this paper. This supports the generalized version of Tipler's theorem in higher dimensional supergravity.

description: The Edwards Plateau is one of the largest continuous karstic regions of the United States; yet, its geomorphic evolution has previously received little systematic study. The objectives of this investigation are to (1) describe the physical characteristics of karstic features, (2) determine which geomorphic and hydrogeologic controls and processes have governed their development, and (3) relate genesis of karst spatially and chronologically to the geomorphic evolution of the Edwards Plateau. Caves provide a record of the evolution of karst and the development of major carbonate aquifers. Some controls on speleogenesis are pervasive; nevertheless, many caves exhibit characteristics that suggest a strong influence of local factors. Lithostratigraphic factors have influenced the development of chambers and passages. Solutional conduits were guided by variations in calcitic and dolomitic content, thickness of strata, and frequency of bedding-plane partings. This is particularly true of the Glen Rose Formation, limestone beds of the Edwards Group, and the Gorman Formation, the three principal cave-forming units. Caves were developed preferentially along fractures associated with regional structural elements, including the Devils River Uplift, Llano Uplift, San Marcos Arch, and Balcones Fault Zone. Locally, faults have modified passages. Evolution of flowpaths within major aquifers has governed the morphology, distribution, and orientation of caves. Patterns of eaves vary markedly and include isolated cavities, interconnected cavities, single conduits, branching conduits, and network, anastomotic, and spongework varieties of mazes. These suggest a diversity of hydrogeologic controls and, in many places, a strong influence of the evolving topography. Most caves of the plateau are relict features, abandoned by groundwater as dissection of the area progressed. They are situated well above floors of valleys and represent early stages of speleogenesis. However, where streams have incised deeply along the Balcones Escarpment and at some places in the interior of the plateau, caves are well integrated, at grade with surficial streams at baselevel, and characteristic of later stages of development. Climatic changes in central Texas during the Quaternary are reflected in siliclastic sediments and speleothems in caves. Ample evidence suggests that caves were severely flooded during periods of colder and wetter climates

description: The Upper Wilcox genetic sequence (UWGS) is a transgressively bounded unit that represents the last major progradational episode associated with Wilcox (Paleocene-Eocene) deposition in the Texas Gulf Coast basin. The UWGS includes at outcrop, the Sabinetown Formation, the Carrizo Formation and the lower Reklaw Formation, and in the subsurface it includes the upper part of the Middle Wilcox Subgroup, all of the Upper Wilcox Subgroup and the lower part of the Reklaw Formation. UWGS depositional systems in the Rio Grande embayment (South Texas) include two large but distinct delta complexes, the Rosita and Burgos deltas. The Rosita delta system contains the Duval, Massive, and Live Oak deltas which were fed by the Carrizo fluvial system. The Burgos delta system contains the Fandango and the Zapata deltas and was fed by an unnamed and unmapped fluvial system originating from northern Mexico. Depositional systems within the UWGS in the Houston embayment (East Texas) include two small delta systems, the Columbus and the Jasper, and an intervening strandplain system, the Harris. The Columbus delta was supplied by the Jewett fluvial system and the Jasper delta by an unnamed and unmapped fluvial system originating in Louisiana. UWGS deposition began following the transgression of the Lower Wilcox shelf margin and the deposition of a regional marine mudstone containing a maximum flooding surface (MFS). An influx of sediment from the west from the last pulse of the Laramide Orogeny (55ma) began deltaic progradation in the Rio Grande embayment. At approximately the same time, delta systems in the Houston embayment first prograded and then were transgressed as the trunk fluvial system shifted to the southwest. The resulting transgressive deposits include the Yoakum shale, which defines the top of the Sabinetown Formation. A fall in sea level at the end of the Yoakum/Sabinetown transgression extended the delta systems in the Rio Grande embayment to the shelf edge; the smaller delta systems in the Houston embayment shifted basinward. A slow relative rise followed as the systems in both embayments continued to prograde/aggrade and then were progressively transgressed. A transgressive shelf with isolated sands ('Atkinson' sands) developed over the drowned basin margin. The Bigford barrier/lagoon complex marked the maximum landward migration of the shoreline

description: Background: The mobile phone has become one of the most frequently used technological innovations in contemporary times. Mobile phones have various applications which have been found useful in the healthcare sector. Its use in improving outcomes in the management of cancer in Nigeria has been documented. Aims: Mobile/cell phone use has become an important socio-medical means of communication. The reason people use a particular ear to answer phone calls more frequently may be associated with hemispheric dominance/ handedness. We aim to determine association between hemispheric and or auditory dominance in laterality in mobile phone use. Study Design: This was a three- month prospective cross-sectional study involving all consenting medical and paramedical respondents. Place and Duration of Study: Hospital community in the University of Benin Teaching Hospital (UBTH), Benin City , Nigeria, between 15th March to 15th June 2018. Method: A modification of the Edinburgh handedness inventory (EHI) was the survey tool. Information retrieved included social demographics, hand most commonly used for activities like writing and picking of phone calls and ear used for phone conversation and the reasons. Data was analyzed using SPSS 19.0 Results: Of the 300 questionnaires distributed, 234 (78%) were completed by the respondents. There were 120(51.3%) males and114 (48.7%) females. Age ranged from 18 - 80years. A total of 201(85.9%) were right handed, 16(6.8%) left handed and 14(6.0%) ambidextrous. One hundred and fifty four (66%) routinely use their right hand to pick phone calls, 50(21.4%) left and 27 (11.5%) use both hands. A total of 141(60%) receive calls with the right ear, 60 (25.6%) with left, and 31(13.2%) had no preference. Reasons advanced for the use of any particular ear included convenience 173 (73.9%), and better acuity 35(15%). Forty two (17.9%) agreed that the use of cell phone made them aware of their poor hearing in a particular ear. Using Pearson’s two tailed test of significance the probability of a right hander using the right hand to pick a phone call and placing it on the right ear is 0.99 or 99%, Vis a Vis left hander. Conclusion: There appears to be an association between hemispheric dominance and laterality when using the mobile phone. This research not only identified the association between hemispheric and auditory superiority in cell phone use, but it also showed that mobile phone apps could be a valuable method for detecting hearing loss.
