description: It is shown that three-dimensional charged black holes can approach the extreme state at nonzero temperature. Unlike even dimensional cases, the entropy for the extreme three-dimensional charged black hole is uniquely described by the Bekenstein-Hawking formula, regardless of different treatments of preparing the extreme black hole, namely, Hawking's treatment and Zaslavskii's treatment.

description: We construct new configurations of oppositely charged, static black hole pairs (diholes) in four dimensions which are solutions of low energy string/M-theory. The black holes are extremal and have four different charges. We also consider diholes in other theories with an arbitrary number of abelian gauge fields and scalars, where the black holes can be regarded as composite objects. We uplift the four-charge solutions to higher dimensions in order to describe intersecting brane-antibrane systems in string and M-theory. The properties of the strings and membranes stretched inbetween these branes and antibranes are studied. Several other generic features of these solutions are discussed.

description: We investigate the constraints on the reionization history of the Universe from a joint analysis of the cosmic microwave background and neutral hydrogen fraction data. The $\tanh$ parametrization and principal component analysis methods are applied to the reionization history respectively. The commonly used $\tanh$ parametrization is oversimplistic when the neutral hydrogen fraction data are taken into account. Using the principal component analysis method, the reconstructed reionization history is consistent with the neutral hydrogen fraction data. With the principal component analysis method, we reconstruct the neutral hydrogen fraction at $z=9.75$ as $x_{\text{HI}}=0.69^{+0.30}_{-0.32}$ for $6

description: The Bisognano-Wichmann property on the geometric behavior of the modular group of the von Neumann algebras of local observables associated to wedge regions in Quantum Field Theory is shown to provide an intrinsic sufficient criterion for the existence of a covariant action of the (universal covering of) the Poincaré group. In particular this gives, together with our previous results, an intrinsic characterization of positive-energy conformal pre-cosheaves of von Neumann algebras. To this end we adapt to our use Moore theory of central extensions of locally compact groups by polish groups, selecting and making an analysis of a wider class of extensions with natural measurable properties and showing henceforth that the universal covering of the Poincaré group has only trivial central extensions (vanishing of the first and second order cohomology) within our class.

description: We study massless and massive Hawking radiations on a two-dimensional AdS spacetime. For the massless case, the quantum stress-energy tensor of a massless scalar field on the AdS background is calculated, and the expected null radiation is obtained. However, for the massive case, the scattering analysis is performed in order to calculate the absorption and reflection coefficients which are related to statistical Hawking temperature. On the contrary to the massless case, we obtain a nonvanishing massive radiation.

Nonsingular global string compactifications

subject: FOS: Physical sciences

description: We consider an exotic `compactification' of spacetime in which there are two infinite extra dimensions, using a global string instead of a domain wall. By having a negative cosmological constant we prove the existence of a nonsingular static solution using a dynamical systems argument. A nonsingular solution also exists in the absence of a cosmological constant with a time-dependent metric. We compare and contrast this solution with the Randall-Sundrum universe and the Cohen-Kaplan spacetime, and consider the options of using such a model as a realistic resolution of the hierarchy problem.

description: This study involves an empirical analysis of the effect of social security wealth on wealth accumulation. My analysis takes as its point of departure a study by Feldstein and Pellechio on this subject. Their study used the same data source as analysed in this paper. Feldstein and Pellechio found strong support for the notion that increases in social security wealth caused families to reduce their wealth accumulation. My resuts indicate the strong conclusions reached by Feldstein and Pellechio are not robust. In particular, first, when I excluded a group, of farmers from our sample increases in social security wealth did not result in families reducing their wealth accumulation. Second, Feldstein and Pellechio calculated social security wealth using income measures from a single year. When I applied their methodlogy to income measures from a different year results were markedly affected.

Multi-Dimensional Elephant Random Walk with Coupled Memory
Creators: name: Marquioni, Vitor M.
Publisher: name: arXiv
Year: 2018
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The elephant random walk (ERW) is a microscopic, one-dimensional, discrete-time, non-Markovian random walk, which can lead to anomalous diffusion due to memory effects. In this study, I propose a multi-dimensional generalization in which the probability of taking a step in a certain direction depends on the previous steps in other directions. The original model is generalized in a straightforward manner by introducing coefficients that couple the probability of moving in one direction with the previous steps in all directions. I motivate the model by first introducing a two-elephant system and then elucidating it with a specific coupling. With the explicit calculation of the first moments, I show the existence of two newsworthy relative movement behaviours: one in which one elephant follows the other, and another in which they go in opposite directions. With the aid of a Fokker-Planck equation, the second moment is evaluated and two new super-diffusion regimes appear, not found in other ERWs. Then, I re-interpret the equations as a bidimensional elephant random walk model, and further generalize it to $N-$dimensions. I argue that the introduction of coupling coefficients is a way of extending any one-dimensional ERW to many dimensions.
description: This is the second revised version of the paper. A detailed analysis of the second moment behavior has been included as also phase diagrams

description: Objective: This study was designed to optimize and develop matrix type transdermal drug delivery system (TDDS) containing tizanidine hydrochloride (TZH) using different polymers by solvent evaporation method. Significance: A strong need exists for the development of transdermal patch having improved bioavailability at the site of action with fewer side effects at off-target organs. Methods: The patches were physically characterized by texture analysis (color, flexibility, smoothness, transparency, and homogeneity), in vitro dissolution test and FTIR analysis. Furthermore, functional properties essential for TDDS, in vitro percentage of moisture content, percentage of water uptake, in vitro permeation by following different kinetic models, in vivo drug content estimation and skin irritation were determined using rabbit skin. Results: The optimized patches were soft, of uniform texture and thickness as well as pliable in nature. Novel transdermal patch showed ideal characteristics in terms of moisture content and water uptake. FTIR analysis confirmed no interaction between TZH and cellulose acetate phthalate (CAP). The patch showed sustained release of the drug which increased the availability of short acting TZH at the site of action. The patch also showed its biocompatibility to the in vivo model of rabbit skin. Conclusions: The results demonstrated that topically applied transdermal patch will be a potential medicated sustain release patch for muscle pain which will improve patient compliance.

description: Objectives: We evaluated the implementation of Prep-to-Play PRO, an injury prevention programme for women’s elite Australian Football League (AFLW). Methods: The Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) of Prep-to-Play PRO were assessed based on the proportion of AFLW players and/or staff who: were aware of the programme (R), believed it may reduce anterior cruciate ligament injury (E), attempted to implement any/all programme components (A), implemented all intended components as practically as possible (I) and intended future programme implementation (M). Quantitative and qualitative data were triangulated to assess 58 RE-AIM items (evidence of yes/no/unsure/no evidence) and the 5 RE-AIM dimensions (fully achieved=evidence of yes on >50% dimension items, partially achieved=50% of items evidence of yes and 50% unsure or 50% mix of unsure and unanswered, or not met=evidence of yes on <50% dimension items). Results: Multiple sources including AFLW training observations (n=7 total), post-implementation surveys (141 players, 25 staff), semistructured interviews (19 players, 13 staff) and internal programme records (9 staff) contributed to the RE-AIM assessment. After the 2019 season, 8 of 10 (80%) AFLW clubs fully met all five RE-AIM dimensions. All 10 clubs participating in the AFLW fully achieved the reach (R) dimension. One club partially achieved the implementation (I) dimension, and one club partially achieved the effectiveness (E) and adoption (A) dimensions. Conclusion: The Prep-to-Play PRO injury prevention programme for the AFLW achieved high implementation, possibly due to the programme’s deliberately flexible approach coupled with our pragmatic definition of implementation. Engaging key stakeholders at multiple ecological levels (organisation, coaches, athletes) throughout programme development and implementation likely enhanced programme implementation.

description: In recent decades, terrestrial dissolved organic matter (DOM) has increased in many northeastern North American and European lakes and is contributing to long-term browning. We used a long-term dataset (1988–2014) to study the consequences of browning-related decreased water transparency on dissolved oxygen dynamics in 2 small temperate lakes in Pennsylvania, USA, that differ in their dissolved organic carbon concentrations. The oligotrophic (“clearer”) lake has low productivity and historically oxygenated deep waters. The mesotrophic–slightly dystrophic (“browner”) lake also has relatively low productivity but historically anoxic deep waters. We examined whether browning coincided with changes in summer dissolved oxygen dynamics, with a focus on deep-water oxygen depletion. In the clearer lake, we found that minimum oxygen concentrations decreased by ∼4.4 mg L−1 over the 27-year period, and these changes were strongly associated with both decreased water transparency and increased water column stability. We also found a shallowing of the maximum dissolved oxygen depth by ∼4.5 m and anoxic conditions established in more recent years. In the browner lake, the metrics we used did not detect any significant changes in dissolved oxygen, supporting the prediction that vertical temperature and oxygen patterns in clearer lakes may be more sensitive to increasing DOM than darker lakes. Anoxia is traditionally considered to be a consequence of anthropogenic nutrient loading and, more recently, a warming climate. We show that browning is another type of environmental change that may similarly result in anoxia in oligotrophic lakes.

description: The State of Qatar is a small peninsula which located in the northeast part of the Arabian Peninsula. It is classified as a subtropical desert with a very extreme harsh climatic conditions in summer and mild winter. Information on Formicidae of Qatar as well as insect fauna is poorly documented, so far only seven species of Formicidae (ants) belonging to five genera have been recorded from Qatar; Brachyponera sennaarensis (Mayr, 1862), Cataglyphis niger (André, 1881), Camponotus maculatus (Fabricius, 1782), Monomorium tumaire (Collingwood and Agosti, 1996), M. pharaonis (Linnaeus, 1758), Trichomyrmex destructor (Jerdon, 1851) and Trichomyrmex mayri (Forel, 1902) (Abdu and Shaumar, 1985; Abushama, 1997; Lush, 2009; Wetterer, 2013 and Sharaf et al., 2016). At least 300 ant species have been recorded from Arabian Peninsula (Collingwood et al., 2011). For instance, Collingwood and Agosti (1996) reported a list of 265 ant species in Saudi Arabia. Collingwood et al. (2011) published a list of more than 120 ant species in UAE. Sharaf et al., (2017) recorded 28 ant species from the Socotra Archipelago, and Sharaf et al., (2018) recorded 123 ant species from Oman. This indicates a significant gap regarding our knowledge on the ant fauna and their diversity in Qatar. In this study ant specimens were collected by using aspirator, direct hand collection, litter sifting and pitfall traps during the period of April 2015 to March 2019 from different sites around the country. In the present study 44 species are newly recorded for the ant fauna of the state of Qatar. By including the present records, the total number of ant species from Qatar has increased to 51 species, including three additional families, 17 additional genera and 44 new species records from Qatar. This study provides the first taxonomic survey of the ant fauna of Qatar. Future investigations will add more information on family Formicidae fauna of this country. (QU, NHMBE)

description: In this paper, we generalize Coleman-Weinberg (CW) inflation in grand unified theories (GUTs) such as $\text{SU}(5)$ and $\text{SO}(10)$ by means of considering two complex singlet fields with conformal invariance. In this framework, inflation emerges from a spontaneously broken conformal symmetry. The GUT symmetry implies a potential with a CW form, as a consequence of radiative corrections. The conformal symmetry flattens the above VEV branch of the CW potential to a Starobinsky plateau. As a result, we obtain $n_{s}\sim 1-\frac{2}{N}$ and $r\sim \frac{12}{N^2}$ for $N\sim 50-60$ e-foldings. Furthermore, this framework allow us to estimate the proton lifetime as $τ_{p}\lesssim 10^{40}$ years, whose decay is mediated by the superheavy gauge bosons. Moreover, we implement a type I seesaw mechanism by weakly coupling the complex singlet, which carries two units of lepton number, to the three generations of singlet right handed neutrinos (RHNs). The spontaneous symmetry breaking of global lepton number amounts to the generation of neutrino masses. We also consider non-thermal leptogenesis in which the inflaton dominantly decays into heavy RHNs that sources the observed baryon asymmetry. We constrain the couplings of the inflaton field to the RHNs, which gives the reheating temperature as $10^{6}\text{ GeV}\lesssim T_{R}<10^{9}$ GeV.

description: Fluorination of the silicon terminated (100) diamond surface under ultra-high vacuum using a molecular fluorine source (C60F48) is investigated with a combination of high resolution photoelectron spectroscopy and low energy electron diffraction. The C60F48 fluorinates the dangling bonds of the silicon-termination on contact, resulting in an inhomogeneous fluorine termination, which remains when the C60F48 is removed by a 550 °C anneal. Despite removing approximately 50% of the surface silicon in the process, the two domain (3 × 1) surface symmetry of the silicon-terminated (100) surface is retained. When exposed to ambient conditions, while some fluorine is displaced by atmosphere exposure, partial fluorination remains. While further optimsation of this process is required for fluorinating diamond in cases where homogeniety and minimised surface damage are desirable, this work demonstrates the potential of the silicon-terminated (100) diamond surface for enabling engineering of the surface properties of diamond.

description: Gamma-ray bursts (GRBs) appear as the brightest transient phenomena in the Universe. The nature of the central engine in GRBs is a missing link in the theory of fireballs to their stellar mass progenitors. Here it is shown that rotating black holes produce electron-positron outflow when brought into contact with a strong magnetic field. The outflow is produced by a coupling of the spin of the black hole to the orbit of the particles. For a nearly extreme Kerr black hole, particle outflow from an initial state of electrostatic equilibrium has a normalized isotropic emission of $\sim 5\times10^{48}(B/B_c)^2(M/7M_\odot)^2\sin^2θ$ erg/s, where B is the external magnetic field strength, B_c=4.4 x 10^{13}G, and M is the mass of the black hole. This initial outflow has a half-opening angle $θ\ge\sqrt{B_c/3B}$. A connection with fireballs in $γ$-ray bursts is given.

description: Elaeidobius kamerunikus Faust dan Thrips hawaiiensis Morgan merupakan polinator utama kelapa sawit. E. kamerunicus dindroduksi dari kamerun pada tahun 1982 sedangkan T. hawaiiensis merupakan polinator natif yang sudah terdapat pada ekosistem perkebunan kelapa sawit di Indonesia. Tujuan penelitian ini untuk mempelajari potensi E. kamerunicus dan T. hawaiiensis sebagai agen polinator pada kelapa sawit. Penelitian ini dilakukan dikebun plasma milik Badan Pengkajian Teknologi Pertanian (BPTP) di Nagari Gunung Medan, Kecamatan Sitiung, Kabupaten Dharmasraya, Provinsi Sumatera Barat. Parameter yang digunakan untuk mengukur potensi serangga polinator yakni kelimpahan populasi, frekuensi kunjungan, dan nilai fruit set dan grade buah, serta rendemen minyak sawit yang dihasilkan. Pengamatan kelimpahan dilakukan dengan mengamati secara langsung populasi serangga tersebut pada bunga jantan kelapa sawit yang sedang anthesis. Frekuensi kunjungan E. kamerunicus dan T. hawaiiensis dilakukan pada bunga betina kelapa sawit yang sedang reseptif dengan menggunakan metode Fix Sample Method. Pengamatan frekuensi kunjungan dilakukan pada pagi, siang dan sore hari. Efektivitas penyerbukan dilakukan dengan melihat nilai fruit set dan grade buah yang dihasilkan. Berdasarkan analisis data hasil pengamatan diketahui bahwa kelimpahan populasi E. kamerunicus lebih tinggi dari pada T. hawaiiensis.

description: Black phosphorus (BP) as a promising two-dimensional material with extraordinary optical properties constitutes an excellent building block in multilayer hyperbolic metamaterials. In this work, we design a multilayer structure composed of BP/dielectric layer stacking unit cells patterned on a gold mirror and theoretically demonstrate the tunable anisotropic absorption in the infrared regime. The electric dipole resonance between the adjacent unit cells drives the structure in the critical coupling state, and impedance of the structure matches to that of free space, showing the perfect absorption for one polarization direction, while the impedance mismatch for the other polarization direction leads to only 8.2$\%$ absorption at the same wavelength. The anisotropic absorption response of the proposed structure can be attributed to the intrinsic anisotropy of BP, which exhibits few dependence on the incident angle. Furthermore, we investigate the tunable optical absorption of the proposed structure with the electron doping of BP and the geometric parameters. These results demonstrate great potentials of BP in constituting multilayer hyperbolic metamaterials, and open up avenues in designing anisotropic metadevices with tunable spectral and polarization selectivity in the infrared regime.

description: There is a canonical mapping from the space of sections of the bundle $\wedge T^\ast M\otimes ST\ M$ to $Ω(T^\ast M ; T(T^\ast M))$. It is shown that this is a homomorphism on $Ω(M;TM) for the Frölicher-Nijenhuis brackets, and also on $Γ(ST\ M)$ for the Schouten bracket of symmetric multi vector fields. But the whole image is not a subalgebra for the Frölicher-Nijenhuis bracket on $Ω(T^\ast M;T(T^\ast M))$.

description: Given a graph G (or more generally a matroid embedded in a projective space), we construct a sequence of varieties whose geometry encodes combinatorial information about G. For example, the chromatic polynomial of G (giving at each m>0 the number of colorings of G with m colors, such that no adjacent vertices are assigned the same color) can be computed as an intersection product between certain classes on these varieties, and other information such as Crapo's invariant find a very natural geometric counterpart. The note presents this construction, and gives `geometric' proofs of a number of standard combinatorial results on the chromatic polynomial.

description: Hydrogen-terminated diamond possesses an intriguing p-type surface conductivity which is induced via thermodynamically driven electron transfer from the diamond surface into surface acceptors such as atmospheric adsorbates, a process called surface transfer doping. High electron affinity transition metal oxides (TMOs) including MoO3 and V2O5 have been shown to be highly effective solid-state surface acceptors for diamond, giving rise to a sub-surface two-dimensional (2D) hole layer with metallic conduction. In this work, low temperature magnetotransport is used as a tool to show the presence of a Rashba-type spin-orbit interaction with a high spin-orbit coupling of 19.9 meV for MoO3 doping and 22.9 meV for V2O5 doping, respectively, through the observation of a transition in the phase-coherent backscattering transport from weak localization to weak antilocalization at low temperature. Surface transfer doping of diamond with TMOs provides a 2D hole system with spin-orbit coupling that is over two times larger than that reported for diamond surfaces with atmospheric acceptors, opening up possibilities to study and engineer spin transport in a carbon material system.
Dirac-Kähler approach connected to quantum mechanics in Grassmann space

description: We compare the way one of us got spinors out of fields, which are a priori antisymmetric tensor fields, to the Dirac-Kähler rewriting. Since using our Grassmann formulation is simple it may be useful in describing the Dirac-Kähler formulation of spinors and in generalizing it to vector internal degrees of freedom and to charges. The ``cheat'' concerning the Lorentz transformations for spinors is the same in both cases and is put clearly forward in the Grassmann formulation. Also the generalizations are clearly pointed out. The discrete symmetries are discussed, in particular the appearance of two kinds of the time-reversal operators as well as the unavoidability of four families.

description: In contrast with the classical gauge group cases, any method to prove exactly the scaling relation which relates moduli and prepotential is not known in the case of exceptional gauge groups. This paper provides a direct method to establish this relation by using Picard-Fuchs equations. In particular, it is shown that the scaling relation found by Ito in N=2 supersymmetric G_2 Yang-Mills theory actually holds exactly.

description: Koiran's real $τ$-conjecture claims that the number of real zeros of a structured polynomial given as a sum of $m$ products of $k$ real sparse polynomials, each with at most $t$ monomials, is bounded by a polynomial in $m,k,t$. This conjecture has a major consequence in complexity theory since it would lead to superpolynomial bounds for the arithmetic circuit size of the permanent. We confirm the conjecture in a probabilistic sense by proving that if the coefficients involved in the description of $f$ are independent standard Gaussian random variables, then the expected number of real zeros of $f$ is $O(mk^2t)$.
description: The first version had an error in the proof of the main theorem, which is now corrected. We also simplified the statement of the Rice inequality (Theorem 3.2), which led to some simplifications

description: This diploma thesis is analyzing the impact and outcome of the Artificial Intelligence use as a business consultant. Initially, it will be analyzed what we define as Artificial Intelligence and what are its characteristics and components but also basic concepts such as management and Big Data. It will then be discussed why companies need innovation in conjunction with other sciences in the field of management (e.g., neuroscience), why they need Artificial Intelligence as an assistant in various fields such as Human Resource Management, pandemic crisis management, cyber risk management as well as in multi-criteria decisions to be made in an environment of uncertainty and risk by creating an appropriate plan. In addition, the Theory of Black Swan is mentioned in order to emphasize the importance of the integration of Artificial Intelligence in companies as a factor of stabilization and balance. Finally, questions are answered about man’s replacement by the advent of technology resulting in the emergence of unprecedented unemployment rates as well as the negative elements of Artificial Intelligence.

description: This paper studies the effects of a multifaceted asset transfer programme on the decision-making dynamics of smallholder households. Constructing separate indexes of participation in household decision-making for adult females and males, and using difference-in-differences to assess the impact of livestock transfer and training, we find evidence that these interventions increased the share of decisions in which individuals participated, regardless of gender. Increases in decision-making participation by both men and women are driven by an increase in joint decision-making within the household on the extensive margin. Decisions made jointly by men and women increased by 16 per cent across all household activities, with statistically significant declines in independent decision-making by men and women. Findings are encouraging given the evidence of welfare gains associated both with increases in participation in decision-making by women as well as increased cooperation within households.
