description: The general objective of the MADFORWATER project is to develop an integrated set of technological and
management instruments for the enhancement of wastewater treatment, treated wastewater reuse for
irrigation and water efficiency in agriculture, with the final aim to reduce water vulnerability in selected
basins in Egypt, Morocco and Tunisia.
In particular, Work Package 3 “Adaptation of technologies for efficient water management and treated
wastewater reuse in agriculture” aims to investigate several technological and non-technological solutions
to enhance the use of treated waste water as alternative source of water for the irrigation sector, and to
adapt them to the local contexts of Egypt, Morocco and Tunisia.
Among the non–technological solutions, in Task 3.3 an agro physical (yield and water balance) - economic
integrated model for land and water use optimization has been built and calibrated in the three case studies
area of MADFORWATER, which are: the irrigated farming system in the Kafr-El- Sheikh Region in Egypt, the
citrus farming system in Souss-Massa region in Morocco and the Nabeul Governorate in Tunisia.
This deliverable presents the integrated model by describing the objective function to be maximized and the
numerous physical (water resources availability, land use and climate change), technological, socio-economic
(production costs, labour, prices) and water policy (pricing, licensing) constraints to be considered. In
addition, the main outputs to be estimated have been identified, and the needed data to run the model that
have been collected and used to calibrate it for the three case studies areas are also presented.

description: In this paper we present a comprehensive formalism for dilepton production from the collision of two polarized spin-12 hadrons by identifying the general angular distribution of the cross section in combination with a complete set of structure functions. The various structure functions are computed in the parton model approximation where we mainly consider the case when the transverse momentum of the dilepton pair is much smaller than its invariant mass. In this kinematical region dilepton production can be described in terms of transverse momentum dependent parton distributions. © 2009 The American Physical Society.
Exact spectrum of the Lipkin-Meshkov-Glick model in the thermodynamic limit and finite-size corrections

description: The spectrum of the Lipkin-Meshkov-Glick model is exactly derived in the thermodynamic limit by means of a spin coherent states formalism. In the first step, a classical analysis allows one to distinguish between four distinct regions in the parameter space according to the nature of the singularities arising in the classical energy surface; these correspond to spectral critical points. The eigenfunctions are then analyzed more precisely in terms of the associated roots of the Majorana polynomial, leading to exact expressions for the density of states in the thermodynamic limit. Finite-size effects are also analyzed, leading in particular to logarithmic corrections near the singularities occuring in the spectrum. Finally, we also compute expectation values of the spin operators in a semi-classical analysis in order to illustrate some subtle effects occuring in one region of the parameter space.

description: The setup of two different small scale teststands for measurements regarding an electron Cherenkov detector as part of the ILC polarimeters is presented. Component measurements already carried out are analyzed and others, foreseen for the near future, are discussed. The larger one of the two teststands features the old Cherenkov detector of the SLD experiment, which will be used as a reference for a number of crucial measurements. Especially, the requirements for the non-linearity of the read-out chain are studied in greater detail and methods for its precise measurement before and during operation are being developed accordingly.

Synthesis and detection of potential N-and α-C- oxidized metabolites of methadone and recipavrin
Creators: name: Slatter, John Gregory
Publisher: name: University of British Columbia
Year: 2010

description: This t he si s describes the attempted characterization of a new metabolite of methadone which was observed by GCMS following β-glucuronidase hydrolysis of conjugated metabolites in the bile of methadone dosed rats. Kang (1) proposed a methylene nitrone structure for this metabolite and suggested that it arose from a glucuronide conjugated secondary hydroxylamine. The nitrone structure was also assigned to a chemical oxidation product of methadone's major metabolite EDDP which had identical GCMS characteristics to the metabolite (1). This thesis shows that the chemical oxidation product was in fact an oxaziridine which, under GC conditions, isomerizes to a formamide, with mass spectrum and retention time identical to the observed metabolite. Attempts to synthesize the potentially thermolabile methylene nitrone structure proposed by Kang failed due to instability of key intermediates or by facile isomerization to the formamide. A model compound, recipavrin, which lacks the ethyl ketone side chain of methadone, was selected to characterize potential N- and α-C-oxidized metabolites and to establish whether formation of the formamide-like metabolite was general to the many drugs containing the 4,4-diphenyl-N,N-dimethyl-2-butylamine structure. The nitrone, oxaziridine and formamide were synthesized as potential N-and α-C- oxidized metabolites of recipavrin and were characterized by GCMS, LCMS, NMR, IR and UV spectroscopy. By exact analogy to methadone, rats treated with recipavrin produced a conjugated metabolite, which upon β-glucuronidase hydrolysis had GCMS characteristics identical to that of the synthetic oxaziridine and formamide. LC and LCMS were not sensitive enough to determine whether the formamide or a thermolabile precursor was responsible for the observed metabolite. While it was not possible to determine which precursor was responsible for the formamide observed by GCMS, there is a good possibility that it is a formamide arising from a tertiary formamide carbinolamine glucuronide.

We present drift velocity and longitudinal diffusion measurements for negative ion gas mixtures using nitromethane as the capture agent. Not only is nitromethane substantially more benign than the only other identified capture agent, CS2, but its low atomic number will enable the use of the NITPC as a photoelectric X-ray polarimeter in the 1-10 keV band. © 2008 Elsevier B.V.

description: Precision measurements with ultracold molecules require development of robust and sensitive techniques to produce and interrogate the molecules. With this goal, we theoretically analyze factors that affect frequency measurements between rovibrational levels of the Sr2 molecule in the electronic ground state. This measurement can be used to constrain the possible time variation of the proton-electron mass ratio. Sr2 is expected to be a strong candidate for achieving high precision due to the spinless nature and ease of cooling and perturbation-free trapping of Sr. The analysis includes calculations of two-photon transition dipole moments between deeply and weakly bound vibrational levels, lifetimes of intermediate excited states, and Stark shifts of the vibrational levels by the optical lattice field, including possibilities of Stark-cancellation trapping. © 2009 The American Physical Society.

description: A model-independent analysis of collinear three-parton correlation functions for fragmentation is performed. By investigating their support properties it is shown, in particular, that the so-called partonic pole matrix elements vanish. This sheds new light on the understanding of transverse single spin asymmetries in various hard semi-inclusive reactions. Moreover, it gives additional strong evidence for the universality of transverse-momentum-dependent fragmentation functions. © 2009 The American Physical Society.
Numerical integration of loop integrals through local cancellation of threshold singularities

description: We propose a new approach that allows for the separate numerical calculation of the real and imaginary parts of finite loop integrals. We find that at one-loop the real part is given by the Loop-Tree Duality integral supplemented with suitable counterterms and the imaginary part is a sum of two-body phase space integrals, constituting a locally finite representation of the generalised optical theorem. These expressions are integrals in momentum space, whose integrands were specially designed to feature local cancellations of threshold singularities. Such a representation is well suited for Monte Carlo integration and avoids the drawbacks of a numerical contour deformation around remaining singularities. Our method is directly applicable to a range integrals with certain geometric properties but not yet fully generalised for arbitrary one-loop integrals. We demonstrate the computational performance with examples of one-loop integrals with various kinematic configurations, which gives promising prospects for an extension to multi-loop integrals.

description: Let n be a positive integer, and let k be a field (of arbitrary characteristic) accessible to symbolic computation. We describe an algorithmic test for determining whether or not a finitely presented k-algebra R has infinitely many equivalence classes of semisimple representations R → Mn (k′), where k′ is the algebraic closure of k. The test reduces the problem to computational commutative algebra over k, via famous results of Artin, Procesi, and Shirshov.

description: The present report documents the results of Working Group 2: B, D and K decays, of the workshop on Flavor in the Era of the LHC, held at CERN from November 2005 through March 2007. With the advent of the LHC, we will be able to probe New Physics (NP) up to energy scales almost one order of magnitude larger than it has been possible with present accelerator facilities. While direct detection of new particles will be the main avenue to establish the presence of NP at the LHC, indirect searches will provide precious complementary information, since most probably it will not be possible to measure the full spectrum of new particles and their couplings through direct production. In particular, precision measurements and computations in the realm of flavor physics are expected to play a key role in constraining the unknown parameters of the Lagrangian of any NP model emerging from direct searches at the LHC. © Springer-Verlag / Società Italiana di Fisica 2008.

description: The number $N(E)$ of complex zeros of the Riemann zeta function with positive imaginary part less than $E$ is the sum of a `smooth' function $\bar N(E)$ and a `fluctuation'. Berry and Keating have shown that the asymptotic expansion of $\bar N(E)$ counts states of positive energy less than $E$ in a `regularized' semi-classical model with classical Hamiltonian $H=xp$. For a different regularization, Connes has shown that it counts states `missing' from a continuum. Here we show how the `absorption spectrum' model of Connes emerges as the lowest Landau level limit of a specific quantum mechanical model for a charged particle on a planar surface in an electric potential and uniform magnetic field. We suggest a role for the higher Landau levels in the fluctuation part of $N(E)$.

Generalized parton correlation functions for a spin-0 hadron
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2008
Subjects: hep-ph

description: The fully unintegrated, off-diagonal quark-quark correlator for a spin-0 hadron is parameterized in terms of so-called generalized parton correlation functions. Such objects are of relevance for the phenomenology of certain hard exclusive reactions. In particular, they can be considered as mother distributions of generalized parton distributions on the one hand and transverse momentum dependent parton distributions on the other. Therefore, our study provides new, model-independent insights into the recently proposed nontrivial relations between generalized and transverse momentum dependent parton distributions. As a by-product we obtain the first complete classification of generalized parton distributions beyond leading twist.

description: This paper describes a way to subdivide a 3-manifold into angled blocks, namely polyhedral pieces that need not be simply connected. When the individual blocks carry dihedral angles that fit together in a consistent fashion, we prove that a manifold constructed from these blocks must be hyperbolic. The main application is a new proof of a classical, unpublished theorem of Bonahon and Siebenmann: that all arborescent links, except for three simple families of exceptions, have hyperbolic complements. © 2008 London Mathematical Society.

description: In this paper, we consider minimal hypersurfaces in the product space $\mathbb{H}^n \times \mathbb{R}$. We begin by studying examples of rotation hypersurfaces and hypersurfaces invariant under hyperbolic translations. We then consider minimal hypersurfaces with finite total curvature. This assumption implies that the corresponding curvature goes to zero uniformly at infinity. We show that surfaces with finite total intrinsic curvature have finite index. The converse statement is not true as shown by our examples which also serve as useful barriers.

description: We consider the effects of temporal delay in a neural feedback system with excitation and inhibition. The topology of our model system reflects the anatomy of the avian isthmic circuitry, a feedback structure found in all classes of vertebrates. We show that the system is capable of performing a `winner-take-all' selection rule for certain combinations of excitatory and inhibitory feedback. In particular, we show that when the time delays are sufficiently large a system with local inhibition and global excitation can function as a `winner-take-all' network and exhibit oscillatory dynamics. We demonstrate how the origin of the oscillations can be attributed to the finite delays through a linear stability analysis.

description: © 2019 authors. Published by the American Physical Society. We report the first measurement of the inclusive jet and the dijet longitudinal double-spin asymmetries, ALL, at midrapidity in polarized pp collisions at a center-of-mass energy s=510 GeV. The inclusive jet ALL measurement is sensitive to the gluon helicity distribution down to a gluon momentum fraction of x≈0.015, while the dijet measurements, separated into four jet-pair topologies, provide constraints on the x dependence of the gluon polarization. Both results are consistent with previous measurements made at s=200 GeV in the overlapping kinematic region, x>0.05, and show good agreement with predictions from recent next-to-leading order global analyses.

description: Essentially all undoped cuprates exhibit a quasi-planar, fourfold Cu-O coordination responsible for the magnetically active antibonding 3d-(x^2-y^2)-like state. Here, we present an electronic structure study for CuSb2O6 that reveals, in contrast, a half-filled 3d-(3z^2-r^2) orbital. This hitherto unobserved ground state originates from a competition of in- and out-of-plaquette orbitals where the strong Coulomb repulsion drives the surprising and unique orbital ordering. This, in turn, gives rise to an unexpected quasi one-dimensional magnetic behavior. Our results provide a consistent explanation of recent thermodynamical and neutron diffraction measurements.

description: Quantal systems are predicted to show a change-over from exponential decay to power law decay at very long times. Although most theoretical studies predict integer power-law exponents, recent measurements by Rothe et al. of decay luminescence of organic molecules in solution {Phys. Rev. Lett. 96 (2006) 163601} found non-integer exponents in most cases. We propose a physical mechanism, within the realm of scattering from potentials with long tails, which produces a continuous range of power law exponents. In the tractable case of the repulsive inverse square potential, we demonstrate a simple relation between the strength of the long range tail and the power law exponent. This system is amenable to experimental scrutiny.

description: Combinig the harmonic balance method (HBM) and a continuation method is a well-known technique to follow the periodic solutions of dynamical systems when a control parameter is varied. However, since deriving the algebraic system containing the Fourier coefficients can be a highly cumbersome procedure, the classical HBM is often limited to polynomial (quadratic and cubic) nonlinearities and/or a few harmonics. Several variations on the classical HBM, such as the incremental HBM or the alternating frequency/time domain HBM, have been presented in the literature to overcome this shortcoming. Here, we present an alternative approach that can be applied to a very large class of dynamical systems (autonomous or forced) with smooth equations. The main idea is to systematically recast the dynamical system in quadratic polynomial form before applying the HBM. Once the equations have been rendered quadratic, it becomes obvious to derive the algebraic system and solve it by the so-called ANM continuation technique. Several classical examples are presented to illustrate the use of this numerical approach.

Localities and specimens found: 50 – 21♀, 10♀ ov, 19j; 51 – 6♀, 2♀ ov, 4j; 60 – 1♀ em.
Distribution and ecology. Chydorus idrisi is an Oriental species. It was described from Vietnam (Sinev 2014), and today it is also known from Thailand, Malaysia and Hainan Island (China) (Sinev & Yusoff 2015, 2018; Sinev et al. 2015; Tiang-nga et al. 2020).
This species was found in the open and vegetated littoral of permanent lakes and reservoirs, as well as in various small and temporary water bodies: rivers, streams, ditches, rice fields, ponds, roadside pools (Sinev 2014; Sinev & Yusoff 2015, 2018; Sinev et al. 2015). In our material, Ch. idrisi was recorded in a temporary forest lake and in a floodplain lake among the roots of floating macrophytes (see Appendix 1). It was especially abundant in the roots of water hyacinth.
Remarks. Prior to its description, Ch. idrisi was apparently confused with other closely related members of the genus, primarily with Ch. pubescens Sars, 1901, Ch. ventricosus Daday, 1898 and Ch. eurynotus Sars, 1901 (Sinev 2014; Ji et al. 2015; Sinev & Yusoff 2015). For example, Ch. cf. pubescens recorded by Idris (1983) in Malaysia is in fact Ch. idrisi (Sinev 2014; Sinev & Yusoff 2015). Thus, the actual distribution of Ch. idrisi is obviously wider than is currently known.

The development and use of imagination in the secondary art curriculum
Creators: name: Bowerman, Mary Jane Daniel
Publisher: name: University of British Columbia
Year: 2010

description: The premise of this thesis is that learning within the classroom is enriched when imaginative thinking and procedures are used in combination with the B.C. "Secondary Art Guide" (1983). The thesis discusses philosophers since Plato until contemporary times and how their ideas continue to affect schooling today, including practical applications in the art classroom. It also investigates twentieth-century educators and philosophers involved with promoting the use of more imaginative thinking in the classroom. Principal applications based on the "Secondary Art Guide" dealing with the thematic units of the Figure and the Environment are given particular emphasis. These units from the guide in combination with assignments to promote individual image-making result in images that are unique to the students. Sixty students from the Vancouver school system formed an integral part of this study by answering questions in a classroom context and by being involved in art assignments. The B.C. "Secondary Art Guide", Foundation section on imagery was found to offer good technical strategies but lacked the necessary strategies for developing imagination that is unique to students. The researcher's conclusion was that by teaching students how to use their imaginations to obtain new knowledge rather than assuming that imaginative thinking and viewing is something they inherently know, that their image-making became more unique with the processes described.

The proposed approach allows for comparing sets of bounding boxes to estimate the degree of similarity of their underlying images. It is based on the fuzzy approach that uses the fuzzy mutual position (FMP) matrix to describe spatial composition and relations between bounding boxes within an image. A method of computing the similarity of two images described by their FMP matrices is proposed and the algorithm of its computation. It outputs the single scalar value describing the degree of content-based image similarity. By modifying the method`s parameters, instead of similarity, the reflectional symmetry of object composition may also be measured. The proposed approach allows for measuring differences in objects` composition of various intensities. It is also invariant to translation and scaling and - in case of symmetry detection - position and orientation of the symmetry axis. A couple of examples illustrate the method.

A Stochastic Mean-Field Approach For Nuclear Dynamics
Creators: name: Ayik, Sakir
Publisher: name: arXiv
Year: 2007
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: We propose a microscopic stochastic approach to improve description of nuclear dynamics beyond the mean-field approximation at low energies. It is shown that, for small amplitude fluctuations, the proposed model gives a result for the dispersion of a one-body observable that is identical to the result obtained previously through a variational approach. Furthermore, by projecting the proposed stochastic mean-field evolution on a collective path, a generalized Langevin equation is derived for collective variable, which incorporate one-body dissipation and one-body fluctuation mechanism in accordance with quantal fluctuation-dissipation relation.

Precision test of mass-ratio variations with lattice-confined ultracold molecules

description: We propose a precision measurement of time variations of the proton-electron mass ratio using ultracold molecules in an optical lattice. Vibrational energy intervals are sensitive to changes of the mass ratio. In contrast to measurements that use hyperfine-interval-based atomic clocks, the scheme discussed here is model independent and does not require separation of time variations of different physical constants. The possibility of applying the zero-differential-Stark-shift optical lattice technique is explored to measure vibrational transitions at high accuracy. © 2008 The American Physical Society.

description: We discuss aspects of antihydrogen studies, that relate to particle physics ideas and techniques, within the context of the ALPHA experiment at CERN's Antiproton Decelerator facility. We review the fundamental physics motivations for antihydrogen studies, and their potential physics reach. We argue that initial spectroscopy measurements, once antihydrogen is trapped, could provide competitive tests of CPT, possibly probing physics at the Planck Scale. We discuss some of the particle detection techniques used in ALPHA. Preliminary results from commissioning studies of a partial system of the ALPHA Si vertex detector are presented, the results of which highlight the power of annihilation vertex detection capability in antihydrogen studies.

Enhanced sensitivity to variation of me/mp in molecular pectra

Publisher: name: My University
Year: 2008
Subjects: physics.atom-ph

description: We propose new experiments with high sensitivity to a possible variation of the electron-to-proton mass ratio μ me/mp. We consider a nearly degenerate pair of molecular vibrational levels, each associated with a different electronic potential. With respect to a change in μ, the change in the splitting between such levels can be large both on an absolute scale and relative to the splitting. We demonstrate the existence of such pairs of states in Cs2, where the narrow spectral lines achievable with ultracold molecules make the system promising for future searches for small variations in μ. © 2008 The American Physical Society.
Reconstructing a model of quintessential inflation

description: We present an explicit cosmological model where inflation and dark energy both could arise from the dynamics of the same scalar field. We present our discussion in the framework where the inflaton field $ϕ$ attains a nearly constant velocity $m_P^{-1} |dϕ/dN|\equiv α+β\exp(βN)$ (where $N\equiv \ln a$ is the e-folding time) during inflation. We show that the model with $|α|<0.25$ and $β<0$ can easily satisfy inflationary constraints, including the spectral index of scalar fluctuations ($n_s=0.96\pm 0.013$), tensor-to-scalar ratio ($r<0.28$) and also the bound imposed on $Ω_ϕ$ during the nucleosynthesis epoch ($Ω_ϕ(1 {\rm MeV})<0.1$). In our construction, the scalar field potential always scales proportionally to the square of the Hubble expansion rate. One may thereby account for the two vastly different energy scales associated with the Hubble parameters at early and late epochs. The inflaton energy could also produce an observationally significant effective dark energy at a late epoch without violating local gravity tests.

description: By using theoretical analysis and molecular dynamics simulations, we investigate the structure of colloidal crystals formed by nonmagnetic microparticles (or magnetic holes) suspended in ferrofluids (called inverse ferrofluids), by taking into account the effect of polydispersity in size of the nonmagnetic microparticles. Such polydispersity often exists in real situations. We obtain an analytical expression for the interaction energy of monodisperse, bidisperse, and polydisperse inverse ferrofluids. Body-centered tetragonal (bet) lattices are shown to possess the lowest energy when compared with other sorts of lattices and thus serve as the ground state of the systems. Also, the effect of microparticle size distributions (namely, polydispersity in size) plays an important role in the formation of various kinds of structural configurations. Thus, it seems possible to fabricate colloidal crystals by choosing appropriate polydispersity in size. © 2008 American Chemical Society.
On the equi-normalizable deformations of singularities of complex plane curves

description: We study a specific class of deformations of curve singularities: the case when the singular point splits to several ones, such that the total $δ$ invariant is preserved. These are also known as equi-normalizable or equi-generic deformations. We restrict primarily to the deformations of singularities with smooth branches. A natural invariant of the singular type is introduced: the dual graph. It imposes severe restrictions on the possible collisions/deformations. And allows to prove some bounds on the variation of classical invariants in equi-normalizable families. We consider in details deformations of ordinary multiple points, the deformations of a singularity into the collections of ordinary multiple points and deformations of the type $x^p+y^{pk}$ into the collections of $A_k$'s.

description: Turn holding, also known as floor holding, refers to practices that a current speaker may deploy to inhibit what might otherwise be hearable as a transition-relevance place (TRP) (see, e.g., Selting 2000). Current speakers thereby work to secure speakership beyond such points, engendering a projected or actual multi-unit turn.

description: Certain exact relations among transverse momentum dependent parton distribution functions due to QCD equations of motion turn into approximate ones upon the neglect of pure twist-3 terms. On the basis of available data from HERMES, we test the practical usefulness of one such "Wandzura-Wilczek-type approximation," namely, of that connecting h1L(1)a(x) to hLa(x), and discuss how it can be further tested by future CLAS and COMPASS data. © 2008 The American Physical Society.
Efficient state transfer in an ultracold dense gas of heteronuclear molecules

description: Polar molecules have bright prospects for novel quantum gases with long-range and anisotropic interactions, and could find uses in quantum information science and in precision measurements. However, high-density clouds of ultracold polar molecules have so far not been produced. Here, we report a key step towards this goal. We start from an ultracold dense gas of loosely bound 40 K 87 Rb Feshbach molecules with typical binding energies of a few hundred kilohertz, and coherently transfer these molecules in a single transfer step into a vibrational level of the ground-state molecular potential bound by more than 10 GHz. Starting with a single initial state prepared with Feshbach association, we achieve a transfer efficiency of 84%. Given favourable Franck-Condon factors, the presented technique can be extended to access much more deeply bound vibrational levels and those exhibiting a significant dipole moment. © 2008 Macmillan Publishers Limited.

description: We investigate the distribution and properties of Faraday rotating and synchrotron emitting regions in the Galactic ISM in the direction of the Galactic anti-centre. We apply Faraday tomography to a radio polarization dataset that we obtained with the WSRT. We developed a new method to calculate a linear fit to periodic data, which we use to determine rotation measures from our polarization angle data. From simulations of a Faraday screen + noise we could determine how compatible the data are with Faraday screens. An unexpectedly large fraction of 14% of the lines-of-sight in our dataset show an unresolved main component in the Faraday depth spectrum. For lines-of-sight with a single unresolved component we demonstrate that a Faraday screen in front of a synchrotron emitting region that contains a turbulent magnetic field component can explain the data.

Prospects for making polar molecules with microwave fields

Publisher: name: My University
Year: 2007
Subjects: quant-ph

description: We propose a mechanism to produce ultracold polar molecules with microwave fields. It converts trapped ultracold atoms into vibrationally excited molecules by a single microwave transition and entirely depends on the existence of a permanent dipole moment in the molecules. As opposed to production of molecules by photoassociation or magnetic-field Feshbach resonances, our method does not rely on properties of excited states or existence of Feshbach resonances. We determine conditions for optimal creation of polar molecules in vibrationally excited states of the ground-state potential by changing frequency and intensity of the microwave field. We also explore the possibility to produce vibrationally cold molecules by combining the microwave field with an optical Raman transition or by applying a microwave field to Feshbach molecules. The production mechanism is illustrated for KRb and RbCs. © 2007 The American Physical Society.

description: Montgomery and Witherspoon proved that upper and lower semisolvable, semisimple, finite dimensional Hopf algebras are of Frobenius type when their dimensions are not divisible by the characteristic of the base field. In this note we show that a finite dimensional, semisimple, lower solvable Hopf algebra is always of Frobenius type, in arbitrary characteristic.
