description: We report the first demonstration of a quantum game on an all-optical one-way quantum computer. Following a recent theoretical proposal we implement a quantum version of Prisoner's Dilemma, where the quantum circuit is realized by a 4-qubit box-cluster configuration and the player's local strategies by measurements performed on the physical qubits of the cluster. This demonstration underlines the strength and versatility of the one-way model and we expect that this will trigger further interest in designing quantum protocols and algorithms to be tested in state-of-the-art cluster resources.

description: Abstract

Cyclophosphamide (CYC) is commonly used in cancer chemotherapy, which causes immunosuppression and tissue oxidative stress at high doses. To enhance the anti-cancer efficacy and reduce the toxicity of CTC, investigating potential adjuvant treatments that can attenuate the adverse effects has been demonstrated. This study explored potential effects of CYC on the hippocampal architechture following the administration of alkaloid isolated from Dioscorea bulbifera. Group A was made the control and given 0.14 ml distilled water for 14 days. Group B were be administered with Cyclophosphamide 150mg / kg only through intraperitoneal route (IP) for 7 days. Group C was administered with Cyclophosphamide 150 mg/ kg and 50 mg / kg of Alkaloid concomitantly for 7 days and Group D was administered Alkaloid for 7 days and then Cyclophosphamide of 150 mg / kg for 7 days. The Alkaloid compound was administered via oral gavage and cyclophosphamide was administered through IP. Administration of Cyclophosphamide (150 g/kg) induced major alterations and has promoted general alteration in the hippocampus and dentate gyrus; furthermore, we can conclude that the Alkaloids (50mg/kg) from Discorea Bulbifera treated the toxicity very minimally but a higher dose could have been more effective. Therefore, the administration of Cyclophosphamide should be strictly monitored and regularly evaluated in individuals treating cancer using this drugs in order to alleviate or prevent some of these alterations.

description: This book is a collection of papers dedicated to the memory of Yehuda Vardi. Yehuda was the chair of the Department of Statistics of Rutgers University when he passed away unexpectedly on January 13, 2005. On October 21--22, 2005, some 150 leading scholars from many different fields, including statistics, telecommunications, biomedical engineering, bioinformatics, biostatistics and epidemiology, gathered at Rutgers in a conference in his honor. This conference was on ``Complex Datasets and Inverse Problems: Tomography, Networks, and Beyond,'' and was organized by the editors. The present collection includes research work presented at the conference, as well as contributions from Yehuda's colleagues. The theme of the conference was networks and other important and emerging areas of research involving incomplete data and statistical inverse problems. Networks are abundant around us: communication, computer, traffic, social and energy are just a few examples. As enormous amounts of network data are collected in this information age, the field has attracted a great amount of attention from researchers in statistics and computer engineering as well as telecommunication providers and various government agencies. However, few statistical tools have been developed for analyzing network data as they are typically governed by time-varying and mutually dependent communication protocols sitting on complicated graph-structured network topologies. Many prototypical applications in these and other important technologies can be viewed as statistical inverse problems with complex, massive, high-dimensional and possibly biased/incomplete data. This unifying theme of inverse problems is particularly appropriate for a conference and volume dedicated to the memory of Yehuda. Indeed he made influential contributions to these fields, especially in medical tomography, biased data, statistical inverse problems, and network tomography.

description: Recent experiments on the antiferromagnetic intercalated transition metal dichalcogenide $\mathrm{Fe_{1/3}NbS_2}$ have demonstrated reversible resistivity switching by application of orthogonal current pulses below its magnetic ordering temperature, making $\mathrm{Fe_{1/3}NbS_2}$ promising for spintronics applications. Here, we perform density functional theory calculations with Hubbard U corrections of the magnetic order, electronic structure, and transport properties of crystalline $\mathrm{Fe_{1/3}NbS_2}$, clarifying the origin of the different resistance states. The two experimentally proposed antiferromagnetic ground states, corresponding to in-plane stripe and zigzag ordering, are computed to be nearly degenerate. In-plane cross sections of the calculated Fermi surfaces are anisotropic for both magnetic orderings, with the degree of anisotropy sensitive to the Hubbard U value. The in-plane resistance, computed within the Kubo linear response formalism using a constant relaxation time approximation, is also anisotropic, supporting a hypothesis that the current-induced resistance changes are due to a repopulating of AFM domains. Our calculations indicate that the transport anisotropy of $\mathrm{Fe_{1/3}NbS_2}$ in the zigzag phase is reduced relative to stripe, consistent with the relative magnitudes of resistivity changes in experiment. Finally, our calculations reveal the likely directionality of the current-domain response, specifically, which domains are energetically stabilized for a given current direction.

description: We present an ultra-high-precision numerical study of the spectrum of multifractal exponents $Δ_q$ characterizing anomalous scaling of wave function moments $$ at the quantum Hall transition. The result reads $Δ_q = 2q(1-q)[b_0 + b_1(q-1/2)^2 + ...]$, with $b_0 = 0.1291\pm 0.0002$ and $b_1 = 0.0029\pm 0.0003$. The central finding is that the spectrum is not exactly parabolic, $b_1\ne 0$. This rules out a class of theories of Wess-Zumino-Witten type proposed recently as possible conformal field theories of the quantum Hall critical point.

The red clump absolute magnitude based on revised Hipparcos parallaxes

Subjects: subject: Astrophysics (astro-ph)

description: Over the past decade the use of the red clump (RC) as distance indicator has increased in importance as this evolutionary phase is well populated and a good local calibration exists. The absolute calibration of the RC in the $I$ and $K$ band is investigated again based on the recently published revised Hipparcos parallaxes. A numerical model is developed that takes the various selection criteria and the properties of the Hipparcos catalogue into account. The biases involved in applying certain selections are estimated with this model. The absolute magnitudes that are found are $M_{\rm I} = -0.22 \pm 0.03$ and $M_{\rm K} = -1.54 \pm 0.04$ (on the 2MASS system). The $I$-band value is in good agreement with previous determinations, the $K$-band value is fainter than previously quoted, and this seems to be related to a selection bias whereby accurate $K$-magnitudes are only available for relatively few bright stars. Applying population corrections to the absolute $K$ magnitude of RC stars in clusters supports the fainter magnitude scale.

The effect of education on farm profit and productivity in Canada
Creators: name: Cunningham-Dunlop, Catherine
Publisher: name: University of British Columbia
Year: 2010

description: This research was undertaken to address the problem of scarce and conflicting evidence concerning the effect of education on farm profit and productivity in Canada. The goals of this thesis were two-fold: to measure the returns accruing to Canadian farm-operators who have generated human capital through the schooling process; and second, to consider the implications of such measurements. A model reflecting the role of education in the decision-making process of Canadian farm-operators was developed. Both the production function approach and the profit function approach were discussed. The variable profit function approach was found to be the most appropriate model for representing the role of schooling in the decision-making process of the Canadian farm-operator. An extension of the variable profit function model was also presented, wherein operator on-farm labour supply and aggregated physical capital were endogenized in a simultaneous equations framework. The main source of data used in the thesis was the Agriculture-Population Linkage data base compiled from information gathered in the 1971 Census and the 1981 Census. The schooling coefficient generally increased as adjustments were made in the model so that more channels of decision-making were open to the farm-operator. These adjustments included the addition of an agricultural research variable, the aggregation of capital into one variable and the movement from a gross sales production function to a variable profit function. Based on estimations of a variable profit function, the marginal profit effect of an additional year of schooling for a Canadian farm-operator was computed to be $1003 (1970 $) using data from the 1971 Census and $3161 (1980 $) using data from the 1981 Census. Estimations of the variable profit function with instrumental variables were found to be successful in describing the role of schooling in the farm-operator's decision-making process. It was concluded that the net returns to schooling in Canadian agriculture are highly positive.

By analyzing the time-dependent dipole moment of Na5 and Na9+, we furthermore show that this can lead to an unphysical self-excitation of the system depending on the system properties and the excitation strength. Analytical aspects, especially the connection between the `Zero-Force Theorem' and the `Generalized-Translation Invariance' of the potential, are discussed.

description: We report the observation of a non-trivial spin texture in Dirac node arcs, novel topological objects formed when Dirac cones of massless particles extend along an open one-dimensional line in momentum space. We find that such states are present in all the compounds of the tetradymite M$_2$Te$_2$X family (M$=$Ti, Zr or Hf and X$=$P or As), regardless of the weak or strong character of the topological invariant. The Dirac node arcs in tetradymites are thus the simplest possible, textbook example, of a type-I Dirac system with a single spin-polarized node arc.

title: Knowledge Graphs and Graph Neural Networks for Semantic Parsing
Creators: name: Sorokin, Daniil
Publisher: name: UNSPECIFIED
Year: 2021

description: Human communication is inevitably grounded in the real world. Existing work on natural language processing uses structured knowledge bases to ground language expressions. The process of linking entities and relations in a text to world knowledge and composing them into a single coherent structure constitutes a semantic parsing problem. The output of a semantic parser is a grounded semantic representation of a text, which can be universally used for downstream applications, such as fact checking or question answering. This dissertation is concerned with improving the accuracy of grounding methods and with incorporating the grounding of individual elements and the construction of the full structured representation into one unified method. We present three main contributions: - we develop new methods to link texts to a knowledge base that integrate context information; - we introduce Graph Neural Networks for encoding structured semantic representations; - we explore generalization potential of the developed knowledge-based methods and apply them on natural language understanding tasks. For our first contribution, we investigate two tasks that focus on linking elements of a text to external knowledge: relation extraction and entity linking. Relation extraction identifies relations in a text and classifies them into one of the types in a knowledge base schema. Traditionally, relations in a sentence are processed one-by-one. Instead, we propose an approach that considers multiple relations simultaneously and improves upon the previous work. The goal of entity linking is to find and disambiguate entity mentions in a text. A knowledge base contains millions of world entities, which span different categories from common concepts to famous people and place names. We present a new architecture for entity linking that is effective across diverse entity categories. Our second contribution is centered on a grounded semantic parser. Previous semantic parsing methods grounded individual elements in isolation and composed them later into a complete semantic representation. Such approaches struggle with semantic representations that include multiple grounded elements, world entities and semantic relations. We integrate the grounding step and the construction of a full semantic representation into a single architecture. To encode semantic representations, we adapt Gated Graph Neural Networks for this task for the first time. Our semantic parsing methods are less prone to error propagation and are more robust for constructing semantic representations with multiple relations. We prove the efficiency of our grounded semantic parser empirically on the challenging open-domain question answering task. In our third contribution, we cover the extrinsic evaluation of the developed methods on three applications: argumentative reasoning, fact verification and text comprehension. We show that our methods can be successfully transferred to other tasks and datasets that they were not trained on.
The metabolism of fluorodopa
Creators: name: Cumming, Paul
Publisher: name: University of British Columbia
Year: 2010

description: Experiments were conducted to characterize the metabolism of ¹⁸F-6-fluorodopa (¹⁸F-D0PA), a compound used as a tracer for the study of dopamine metabolism in human subjects by means of positron emission tomography (PET). Analysis of plasma from carbidopa pretreated humans, monkeys and rats showed that ¹⁸F-D0PA disappeared rapidly and that the principal plasma metabolite was 0-methyl-¹⁸F-D0PA. The kinetics of both ¹⁸F-D0PA and total ¹⁸F disappearance in the three species were found to be biexponential. In human subjects, some components of plasma ¹⁸F-D0PA metabolism were found to be age dependent. Inhibition of catechol-0-methyltransferase (COMT) with U-0521 increased greatly the persistance of ¹⁸F-D0PA in plasma of the rat. Cerebral tissues of the male hooded rat were analyzed by high preformance liquid chromatography at various times after ¹⁸F-D0PA administration. Me-¹⁸F-D0PA was found to accumulate rapidly in striatum, cortex and cerebellum. Striatum differed from other tissues in that radioactivity levels were maintained at a fairly constant level for two hours, during which time radioactivity washed out of other brain regions. This radiocontrast was found to be due to the formation of ¹⁸F-fluorodopamine and subsequent metabolites in striatum. Inhibition of COMT with U-0521 increased the amount of ¹⁸F-fluorodopamine in striatum by 50% over a 90 minutes period, but this only produced a marginal increase in radiocontrast because of the remaining background activity due to Me-¹⁸F-D0PA. The kinetics of the decarboxylation of 6-¹⁸F-D0PA were determined in vitro to be very similar to literature values reported for L-DOPA. In contrast, 2-¹⁸F-fluorodopa was a poor substrate for the decarboxylase.

description: We investigate the effect of the thermal imbalance on the structural stability of the magnetohydrodynamic model of the preflare current layer (Ledentsov, Sol. Phys. 296, 74, 2021). The piecewise homogeneous model of the current layer is supplemented by a magnetic field longitudinal with respect to the direction of the current. It is shown that the presence of a weak longitudinal field does not change the previously calculated spatial period of the thermal instability in the most expected range of the parameters of the preflare current layer and, moreover, contributes to the formation of the instability. On the other hand, a strong longitudinal magnetic field contributes to the spatial stabilization of the current layer.

 Breeding season, distribution, habitat and density. The breeding season of cyprius, with eggs Apr–May and chicks late Apr–Jul (Flint & Stewart 1992 and subsequent Cyprus Bird Reports) is several weeks earlier than in Turkey (Kirwan et al. 2008). Breeding birds are common in towns, villages, lightly wooded areas, and open pine Pinus brutia forest to 1,900 m (Flint & Stewart 1992 and subsequent Cyprus Bird Reports; Ieronymidou 2008; Pomeroy & Walsh 2013; J. Honold pers. comm.). Habitats of cyprius thus appear generally similar to those of scops except that cyprius is common in pine forest, whereas scops (except O. s. pulchellus) infrequently inhabits conifers (Cramp 1985).
 The density of singing male cyprius is high: 3–4 (exceptionally 8–10, Charalambides & Charalambides 1990) are often heard from one point simultaneously in favoured areas, and counts in and around villages often involve 10–12, exceptionally 20 (e.g. Charalambides & Charalambides 1983; Sanders 2000; Gordon et al. 2004; Richardson et al. 2012; C. Richardson pers. comm.). High breeding densities have been recorded in scops (Cramp 1985), but those for cyprius seem to be usually greater, apparently much more so than on Corsica (Thibault & Bonaccorsi 1999). The estimated breeding population of cyprius of 10,000–20,000 pairs (BirdLife International 2004) or 5,000–15,000 pairs (BirdLife Cyprus 2013 estimate) is relatively high compared to those in the much larger nearby countries of Greece and Turkey (BirdLife International 2004), suggesting that mean density on Cyprus is higher. However, estimates of densities of singing male cyprius across a range of habitats are required to enable more accurate comparisons.

description: Two groups of astronomers used the large telescopes Keck and VLT for decades to observe trajectories of bright stars near the Galactic Centre. Based on results of their observations the astronomers concluded that trajectories of the stars are roughly elliptical and foci of the orbits are approximately coincide with the Galactic Centre position. In a last few years a self-gravitating dark matter core--halo distribution was suggested by Ruffini, Arguelles, Rueda (RAR) and this model was actively used in consequent studies. In particular, recently it has been claimed that the RAR-model provides a better fit of trajectories of bright stars in comparison to the conventional model with a supermassive black hole. The dark matter distribution with a dense core having a constant density as it was suggested in the RAR-model leaves trajectories of stars elliptical like in Kepler's two-body problem. However, in this case not the foci of the ellipses coincide with the Galactic Center but their centers while the orbital periods do not depend on semi-major axes. These properties are not consistent with the observational data for trajectories of bright stars.

description: We used adaptive mesh refinement hydrodynamic cosmological simulations of a $z=1$ Milky Way-type galaxy and a $z=0$ Dwarf galaxy and generated synthetic quasar absorption-line spectra of their circumgalactic medium (CGM). Our goal is to assess whether standard observational spectroscopic analysis methods accurately reproduce intrinsic column densities, metallicities [Si/H], and hydrogen densities $n_{H}$, in simulated absorption-line systems. Without knowledge of the intrinsic simulated properties (blind study), we analysed synthetic COS and HIRES spectra with fixed $S/N=30$ to determine the column densities, metallicity, and $n_{H}$, using Voigt profile fitting combined with Markov-Chain Monte-Carlo single-phase {\sc Cloudy} modelling techniques. To quantify the intrinsic simulated absorbing gas properties, we objectively determined which gas cells along a line of sight (LOS) contribute to detected absorption in the spectra and adopt the unweighted geometric mean of these gas cell properties. For this pilot study, we performed this experiment for five LOS in the Milky-Way galaxy and five LOS in the Dwarf galaxy. We found an average agreement between the "observed" and intrinsic metallicity overestimated within $0.8σ$ or $0.2$ dex for the "Milky-Way"' CGM and overestimated within $1.4σ$ or $0.2$ dex for the Dwarf galaxy CGM. We found that the spectroscopically-derived $n_{H}$ are underestimated within $0.8σ$ or $0.4$ dex of the intrinsic $n_{H}$ for the "Milky-Way" CGM and overestimated within $0.3σ$ or $0.3$ dex for the Dwarf galaxy CGM. The overall agreement suggests that, for single-phase ionisation modelling of systems where there is substantial spread in gas properties, global metallicity measurements from quasar absorption line studies are capturing the average metallicity and ionisation parameters in a given astrophysical environment.

description: It has been proposed recently to observe the change in cosmological redshift of distant galaxies or quasars with the next generation of large telescope and ultra-stable spectrographs (the so-called Sandage-Loeb test). Here we investigate the possibility of observing the change in peculiar velocity in nearby clusters and galaxies. This ``peculiar acceleration'' could help reconstructing the gravitational potential without assuming virialization. We show that the expected effect is of the same order of magnitude of the cosmological velocity shift. Finally, we discuss how to convert the theoretical predictions into quantities directly related to observations.

description: We show that the recipe for computing the expansions $θ_\ell$ and $θ_n$ of outgoing and ingoing null geodesics normal to a surface admits a covariance group with nonconstant scalar $κ(x)$, corresponding to the mapping $θ_\ell \to κθ_\ell$, $θ_n \to κ^{-1} θ_n$. Under this mapping, the product $θ_\ell θ_n$ is invariant, and thus the marginal surface computed from the vanishing of $θ_\ell$, which is used to define the apparent horizon, is invariant. This covariance group naturally appears in comparing the expansions computed with different choices of coordinate system.

In high-rise building construction, big prefabricated wall panels must be aligned to the side face of the building with millimetre precision. The conventional methods are unsafe and inefficient — the crane driver can't see what they are doing, and the workers risk being struck, crushed, or falling from a height. Brandon's work contributes to developing the core processes and technologies that are required to make automated localisation of the crane borne panel viable.

description: Utilizing the first-principles calculations together with the group theory analysis, we systematically investigate the magnetocrystalline anisotropy energy, magneto-optical effect, and anomalous transport properties (including anomalous Hall, Nernst, and thermal Hall effects) of monolayer and bilayer Fe$_n$GeTe$_2$ ($n$ = 3, 4, 5). The monolayer Fe$_n$GeTe$_2$ ($n$ = 3, 4, 5) exhibits the out-of-plane, in-plane, and in-plane ferromagnetic orders with considerable magnetocrystalline anisotropy energies of -3.17, 4.42, and 0.58 meV/f.u., respectively. Ferromagnetic order is predicted in bilayer Fe$_4$GeTe$_2$ while antiferromagnetic order prefers in bilayer Fe$_3$GeTe$_2$ and Fe$_5$GeTe$_2$. The group theory analysis reveals that in addition to monolayer ferromagnetic Fe$_n$GeTe$_2$ ($n$ = 3, 4, 5), the magneto-optical and anomalous transport phenomena surprisingly exist in bilayer antiferromagnetic Fe$_5$GeTe$_2$, which is much rare in realistic collinear antiferromagnets. If spin magnetic moments of monolayer and bilayer Fe$_n$GeTe$_2$ are reoriented from the in-plane to out-of-plane direction, the magneto-optical and anomalous transport properties enhance significantly, presenting strong magnetic anisotropy. We also demonstrate that the anomalous Hall effect decreases with the temperature increases. The gigantic anomalous Nernst and thermal Hall effects are found in monolayer and bilayer ferromagnetic Fe$_n$GeTe$_2$, and the largest anomalous Nernst and thermal Hall conductivities, respectively, of -3.31 A/Km and 0.22 W/Km at 130 K are observed in bilayer ferromagnetic Fe$_4$GeTe$_2$. Especially, bilayer antiferromagnetic Fe$_5$GeTe$_2$ exhibits large zero-temperature anomalous Hall conductivity of 2.63 e$^2$/h as well as anomalous Nernst and thermal Hall conductivities of 2.76 A/Km and 0.10 W/Km at 130 K, respectively.

title: Literature and Intercultural Communicative Competence (ICC) Promoting ICC Through a Content-Based Approach To “My Son The Fanatic” (H. Kureishi)

description: Literary texts have an increasingly prominent role in EFL (English as Foreign Language) classes. Accordingly, more academic studies about the role of literature in foreign language learning have been published in the past decade. Nevertheless, how literature can promote the development of Intercultural Communicative Competence (ICC) has not been sufficiently explored. The research question in this study was: How can teaching literary texts in the EFL classroom promote ICC? The study was carried out in a 12th-year class in which the students studied the short story “My Son the Fanatic” by Hanif Kureishi (1997). I argue that a content-based approach that promotes the development of the students’ affective and cognitive dimensions during reading may develop ICC. This required the adoption of a reading model comprised of two stages, the first of which is affective and spontaneous, while the second is reflexive, requiring supporting viewpoints with evidence and discussing, as well as comparing them with one’s peers, which is one of the tenets of constructivism and, therefore, a content-based approach. The transformation of attitudes and beliefs, which in turn causes changes in more spontaneous reading happens in a third space, which is hybrid because it does not correspond fully to the students’ culture nor to those represented in the text. By adopting this approach, the students were able to reflect on their own culture, become aware of how their beliefs, behaviours and identities condition their interpretation of the short story and, as a result, develop several domains of ICC.

description: We introduce an atomic gravimetric sequence using Raman-type composite light pulses that excites a superposition of two momentum states with the same internal level. The scheme allows the suppression of common noise, making it less sensitive to external fluctuations of electromagnetic fields. The Raman beams are generated with a fiber modulator and are capable of momentum transfer in opposite directions. We obtain analytical expressions for the interference fringes in terms of three perturbative parameters that characterize the imperfections due to undesired frequencies introduced by the modulation process. We find special values of the Rabi frequency that improve the fringes visibility.

description: A hybrid Car-Parrinello QM/MM molecular dynamics simulation has been carried out for the Watson-Crick base pair of 9-ethyl-8-phenyladenine and 1-cyclohexyluracil in deuterochloroform solution at room temperature. The resulting trajectory is analyzed putting emphasis on the N-H$...$N Hydrogen bond geometry. Using an empirical correlation between the $\NN$-distance and the fundamental NH-stretching frequency, the time-dependence of this energy gap along the trajectory is obtained. From the gap-correlation function we determine the infrared absorption spectrum using lineshape theory in combination with a multimode oscillator model. The obtained average transition frequency and the width of the spectrum is in reasonable agreement with recent experimental data.

description: Background: Deep learning technologies can learn complex patterns from input patient data (ex; histopathology, DNA methylation) to predict clinically useful cancer-related endpoints (ex; survival). Multimodal methods fuse together information from heterogeneous modalities, to make more informed predictions. The tumor microenvironment (TME) is characterized by a mosaic of immune cell types whose composition – which can be deconvolved from “omics” data – may hold clues regarding a patient’s unique disease profile and progression. Existing deep learning-driven multimodal methods do not incorporate this important data type into machine learning prognostication models. 



Methods: Here, we develop a multimodal deep learning model which integrates patient histopathological imaging, bulk DNA methylation profiling, and deconvolved cellular proportions from 17 lineages using HiTIMED, to predict colorectal cancer patient prognosis (ie: instantaneous risk of death). Data was collected and preprocessed from 414 patients from The Cancer Genome Atlas (TCGA). Unimodal prognostication models were trained to derive numerical representations from each modality. The final multimodal model fused together these representations to learn a joint information space and subsequently predict patient prognosis. Models were assessed using concordance index (c-index) measured on a heldout testing dataset partition.



Results and Conclusions: Unimodal models using histopathology (0.593 ± 0.003), DNA methylation (0.615 ± 0.001), and immune cell proportions (0.623 ± 0.003) were similarly powerful independent predictors of prognosis measured via C-Index. The multimodal model (0.672 ± 0.002) brought an average performance increase of 4.4%. This performance was comparable and potentially superior versus other reported multimodal colorectal cancer prognostication methods (0.640 ± 0.007, 0.650 ± 0.005). Our results demonstrate that TME-related cell profiles should be considered a capable modality for independent and joint investigation of actionable cancer outcome prediction. Future works will apply this modality to additional predictive tasks, and conduct ablation studies to understand how TME data can uncover novel biological insights.

description: An exact solution for the bulk 5-dimensional geometry is derived for F(R) gravity with non-flat de-Sitter 3-branes located at the $M_4 \times Z_2$ orbifold boundaries. The corresponding form of F(R) that leads to such an exact solution of the bulk metric is derived which turns out to have all positive integer powers of R.In such a scenario the stability issue of the modulus (radion field) is analyzed critically for different curvature epochs in both Einstein and Jordan frames. The radion in the effective 4-d theory exhibits a phantom epoch making this model viable for a non-singular bounce. Simultaneous resolution of the gauge hierarchy problem is exhibited through the resulting stable vaue of the radion field in the effective $3+1$ dimensional theory.

description: Conventionally we collect electron and up/down-quarks (u,d)+(nu_e,e) to form unified generations, and collect the left-handed and the right-handed fermions of the same flavors (nu_e,e)+e^c. We can alternatively have a contorted multiplet, made by pairing different quarks and leptons, like (u,d)+(nu_mu,mu) or (u,d)+(nu_tau,tau), and/or between different left and right handed fermions to (nu_e,e)+mu^c, etc. These can suppress proton decay, due to its high flavor dependence, while having the correct fermion masses.
