description: The upper limit on the mass of the lightest CP-even neutral Higgs in the minimal supersymmetric standard model is around 135 GeV for soft supersymmetry breaking masses in the 1 TeV range. We demonstrate that this upper limit may be sizably relaxed if supersymmetry is embedded in extra dimensions. We calculate, using the effective potential technique, the radiative corrections to the lightest Higgs mass induced by the Kaluza-Klein towers of quarks and squarks with one and two compactified directions. We observe that the lightest Higgs may comfortably weigh around 200 GeV (300 GeV) with one (two) extra dimension(s).

description: GaInP solar cells are a major component of III-V multi-junction high-efficiency solar cells. Due to the
structural complexity of these devices numerical modeling is crucial for design optimization, as well as for the
understanding of the cell physics. This work presents results based on a 2D model of state-of-the-art single junction
GaInP solar cells within the commercial simulation environment Sentaurus TCAD from Synopsys. The model is
validated by comparing calculated cell reflection, external quantum efficiency (EQE) and current-voltage (JV)
characteristic with experimental data. For this purpose GaInP solar cells with deliberate structural variations were
fabricated and characterized. The obtained model provides a platform for cell design and a deeper insight to the cell
physics. Here the influence of the base layer properties and the window-emitter interface on the cell characteristics is
studied.

Minimal surfaces with planar boundary curves

Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics
subject: 53A10

description: We consider compact connected minimal surfaces, with a pair of boundary curves (not necessarily convex) in distinct planes, that have least-area amongst all orientable surfaces with the same boundary. When the planes containing these two boundary curves are either parallel or sufficiently close to parallel, and when the boundary curves themselves are sufficiently close to each other, we draw specific conclusions about the geometry and topology of the surfaces. We also strength the following result: Let $M$ be any compact minimal annulus with two planar boundary curves of diameters $d_1$ and $d_2$ in parallel planes $P_1$ and $P_2$; if the distance between $P_1$ and $P_2$ is $h$, then the inequality $h \leq {3/2}\max\{d_1,d_2\}$ is satisfied. We strength it by removing the assumption that $M$ is an annulus and by showing that the stronger conclusion $h \leq \max\{d_1,d_2\}$ holds. We also include a similar result for nonminimal constant mean curvature surfaces.

description: This is a survey article on two topics. The Energy E of knots can be obtained by generalizing an electrostatic energy of charged knots in order to produce optimal knots. It turns out to be invariant under Moebius transformations. We show that it can be expressed in terms of the infinitesimal cross ratio, which is a conformal invariant of a pair of 1-jets, and give two kinds of interpretations of the real part of the infinitesimal cross ratio.

description: The odd isotopologues of ytterbium monohydroxide, $^{171,173}$YbOH, have been identified as promising molecules in which to measure parity (P) and time reversal (T) violating physics. Here we characterize the $\tilde{A}^{2}Π_{1/2}(0,0,0)-\tilde{X}^2Σ^+(0,0,0)$ band near 577 nm for these odd isotopologues. Both laser-induced fluorescence (LIF) excitation spectra of a supersonic molecular beam sample and absorption spectra of a cryogenic buffer-gas cooled sample were recorded. Additionally, a novel spectroscopic technique based on laser-enhanced chemical reactions is demonstrated and utilized in the absorption measurements. This technique is especially powerful for disentangling congested spectra. An effective Hamiltonian model is used to extract the fine and hyperfine parameters for the $\tilde{A}^{2}Π_{1/2}(0,0,0)$ and $\tilde{X}^2Σ^+(0,0,0)$ states. A comparison of the determined $\tilde{X}^2Σ^+(0,0,0)$ hyperfine parameters with recently predicted values (M. Denis, et al., J. Chem. Phys. $\bf{152}$, 084303 (2020), K. Gaul and R. Berger, Phys. Rev. A $\bf{101}$, 012508 (2020), J. Liu et al., J. Chem. Phys. $\bf{154}$, 064110 (2021)) is made. The measured hyperfine parameters provide experimental confirmation of the computational methods used to compute the P,T-violating coupling constants $W_d$ and $W_M$, which correlate P,T-violating physics to P,T-violating energy shifts in the molecule. The dependence of the fine and hyperfine parameters of the $\tilde{A}^{2}Π_{1/2}(0,0,0)$ and $\tilde{X}^2Σ^+(0,0,0)$ states for all isotopologues of YbOH are discussed and a comparison to isoelectronic YbF is made.

description: We give an overview of ISINA: INTEGRAL Source Identification Network Algorithm. This machine learning algorithm, using Random Forests, is applied to the IBIS/ISGRI dataset in order to ease the production of unbiased future soft gamma-ray source catalogues. First we introduce the dataset and the problems encountered when dealing with images obtained using the coded mask technique. The initial step of source candidate searching is introduced and an initial candidate list is created. A description of the feature extraction on the initial candidate list is then performed together with feature merging for these candidates. Three training and testing sets are created in order to deal with the diverse timescales encountered when dealing with the gamma-ray sky. Three independent Random Forest are built: one dealing with faint persistent source recognition, one dealing with strong persistent sources and a final one dealing with transients. For the latter, a new transient detection technique is introduced and described: the Transient Matrix. Finally the performance of the network is assessed and discussed using the testing set and some illustrative source examples.

Can Extra Mixing in RGB and AGB Stars Be Attributed to Magnetic Mechanisms?

description: It is known that there must be some weak form of transport (called cool bottom processing, or CBP) acting in low mass RGB and AGB stars, adding nuclei, newly produced near the hydrogen-burning shell, to the convective envelope. We assume that this extra-mixing originates in a stellar dynamo operated by the differential rotation below the envelope, maintaining toroidal magnetic fields near the hydrogen-burning shell. We use a phenomenological approach to the buoyancy of magnetic flux tubes, assuming that they induce matter circulation as needed by CBP models. This establishes requirements on the fields necessary to transport material from zones where some nuclear burning takes place, through the radiative layer, and into the convective envelope. Magnetic field strengths are determined by the transport rates needed by CBP for the model stellar structure of a star of initially 1.5 solar mass, in both the AGB and RGB phases. The field required for the AGB star in the processing zone is B_0 ~ 5x10^6 G; at the base of the convective envelope this yields an intensity B_E < 10^4 G (approximately). For the RGB case, B_0 ~ 5x10^4 to 4x10^5 G, and the corresponding B_E are ~ 450 to 3500 G. These results are consistent with existing observations on AGB stars. They also hint at the basis for high field sources in some planetary nebulae and the very large fields found in some white dwarfs. It is concluded that transport by magnetic buoyancy should be considered as a possible mechanism for extra mixing through the radiative zone, as is required by both stellar observations and the extensive isotopic data on circumstellar condensates found in meteorites.

Magnetically Regulated Star Formation in 3D: The Case of Taurus Molecular Cloud Complex
Creators: name: Nakamura, Fumitaka

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We carry out three-dimensional MHD simulations of star formation in turbulent, magnetized clouds, including ambipolar diffusion and feedback from protostellar outflows. The calculations focus on relatively diffuse clouds threaded by a strong magnetic field capable of resisting severe tangling by turbulent motions and retarding global gravitational contraction in the cross-field direction. They are motivated by observations of the Taurus molecular cloud complex (and, to a lesser extent, Pipe Nebula), which shows an ordered large-scale magnetic field, as well as elongated condensations that are generally perpendicular to the large-scale field. We find that stars form in earnest in such clouds when enough material has settled gravitationally along the field lines that the mass-to-flux ratios of the condensations approach the critical value. Only a small fraction (of order 1% or less) of the nearly magnetically-critical, condensed material is turned into stars per local free-fall time, however. The slow star formation takes place in condensations that are moderately supersonic; it is regulated primarily by magnetic fields, rather than turbulence. The quiescent condensations are surrounded by diffuse halos that are much more turbulent, as observed in the Taurus complex. Strong support for magnetic regulation of star formation in this complex comes from the extremely slow conversion of the already condensed, relatively quiescent C$^{18}$O gas into stars, at a rate two orders of magnitude below the maximum, free-fall value. We analyze the properties of dense cores, including their mass spectrum, which resembles the stellar initial mass function.

description: Results of an analysis of the BRITE-Constellation and SMEI photometry and radial-velocity observations, archival and new, of two single-lined spectroscopic binary systems $ν$ Centauri and $γ$ Lupi are reported. In the case of $γ$ Lup AB, a visual binary, an examination of the light-time effect shows that component A is the spectroscopic binary. Both $ν$ Cen and $γ$ Lup exhibit light variations with the orbital period. The variations are caused by the reflection effect, i.e. heating of the secondary's hemisphere by the early-B main sequence (MS) primary component's light. The modelling of the light curves augmented with the fundamental parameters of the primary components obtained from the literature photometric data and Hipparcos parallaxes, shows that the secondary components are pre-MS stars, in the process of contracting onto the MS. $ν$ Cen and $γ$ Lup A are thus found to be non-eclipsing counterparts of the B2 IV eclipsing binary (and a $β$ Cephei variable) 16 (EN) Lac, the B5 IV eclipsing binary (and an SPB variable) $μ$ Eri, and the recently discovered LMC nascent eclipsing binaries.

description: This paper reports the results obtained in 30 years of measurements and monitoring with the PV plant TISO
10 kW, which is installed at SUPSI in Southern Switzerland. The plant was connected in May 1982 to the grid as the first
in Europe. The system worked for 27 years almost without interruptions; only few times the plant underwent configuration
changes only a few times during this period mainly because of inverter breakdowns. Due to a change in location at
the end of 2008 the disassembling of the system was begun, and 18 month later the plant was reinstalled in a new configuration
on a different roof. Between 1982 and 2010 the IV curves of 18 selected modules were measured regularly.
Performance measurement, visual inspection and insulation testing was performed on all modules of the plant in 2001
and 2009/2010. The average degradation of all modules of the plant over the 28 years is 0.38 %/year. In the first period
(1982-2001), the degradation was 0.27%/year and in the second period (2001-2009) 0.64% / year. The performance ratio
of the system decreased by about 20% in the 27 years of operation, and increased 10% after maintenance and reinstallation
of the plant.

This work allowed us showing that the diamond-wire based sawing method induces a smoother wafer surface and

description: We present a study on preparing and manipulating path-like temporal-mode (TM) qubits based on third-order nonlinear interactions. Specifically, we consider the process of frequency conversion via difference frequency generation. To prepare a qubit, we aim to use Gaussian input states to a nonlinear waveguide. The coupling between the input state and a specific TM is maximized, obtaining qubits prepared with fidelities close to one. TMs evolve linearly within the medium; therefore, it is possible to define rotations around any axis contained in the $xy$ plane, allowing spanning the full Bloch sphere in two steps. Particularly, we present a method to obtain any of the Pauli quantum gates by varying geometric or user-accessible parameters in a given experimental configuration. Our study allows for experimentally feasible proposals capable of controllable arbitrary qubit transformations.

description: Colored photovoltaic (PV) modules have been manufactured with monolayer interferential filters
integrated directly onto bulk Si PV cells or on large surface glass covers. Whatever the color, the filters’ conception is
such that the relative short circuit current loss is designed and experimentally verified to be less than 15%. Somehow
the higher series resistance of the purple PV cells with the thickest SiN layer on Si induces an important fill factor
loss. The best conversion yield is obtained with the PV cells grey color for which the relative power loss is only 8 %.
Coloring the glass cover is the best way to obtain conversion yield losses which are limited by the theoretical current
losses. Colors can be brought to PV modules at a production cost that is equivalent to the standard blue modules.

description: Wafer slicing using fixed abrasives (FAS) can contribute significantly to reducing the cost of cutting
mono-crystalline silicon bricks. The environmental and economic drawbacks of standard slurry-based slicing are
eliminated. Efficient regeneration of spent coolant solutions is a necessary prerequisite. Major goals are complete
removal of Si particles, reclaim of large amounts of coolant solution suitable for re-use, low Total Cost of Ownership
(TCO), ease of use, robustness, and reduced waste. Re-use of regenerated coolant makes fixed abrasive wafer slicing
(FAS) competitive and reduces TCO of coolant supply by 90 %. The re-use rate needs to be restricted to not more than
90–95 % in order to avoid the accumulation of dissolved contaminants and to control coolant quality. Only crossflow
membrane filtration (MF) is capable of providing sufficient coolant quality at consistent filtrate flow and satisfactory
coolant reclaim rate. An integrated coolant regeneration system includes a tank system and one or two stages of MF
systems, equipped with the proper membrane modules. Concentrate dewatering is preferably integrated into the
wastewater treatment plant. Long-term experience on sites in US, Asia and Europe gives credence to this approach and
suggests additional measures for further optimization.

description: The Comparative Method is a primary tool of historical linguists that traditionally focuses on segmental evidence. Lexical tone has been used as an example of where the method is not applicable. Using data from hundreds of Tai doculects, this paper models extending the logic of the Comparative Method to lexical tone. Insights from computational phylogenetics assist in distinguishing shared innovation from shared retention and parallel innovation in tonal sound change. This approach represents an increase in rigor in the study of Tai language history, and serves as a model for studying sound change in lexical tone languages more generally.

At the moment different forecast models are available and the market grows fast. In order to give an overview of the

Important criteria for the evaluation of solar forecast systems were determined and brought together in the questionnaire
"Use of solar and PV forecasts for enhanced PV integration".
The questionnaire included a total of 34 questions grouped in 7 blocks about temporal range, post processing schemes,
additional parameters, spatial information, forecast evaluations and uncertainties. It was aiming at shortest (0 – 6 h) as
well as short term (6 – 72 h) and at statistical as well as deterministic forecasts. 14 organizations have filled in the
questionnaire. The organizations are from the private and public sectors (universities and meteorological offices) and are
based in North America, Europe and Japan.

Electrochemistry, Ion Adsorption and Dynamics in the Double Layer: A Study of NaCl(aq) on Graphite

description: Graphite is a ubiquitous electrode material with particular promise for use in e.g., energy storage and desalination devices, but very little is known about the properties of the graphite-electrolyte double layer at technologically relevant concentrations. Here, the (electrified) graphite-NaCl(aq) interface was examined using constant chemical potential molecular dynamics simulations; this approach avoids ion depletion (due to surface adsorption) and maintains a constant concentration of ions beyond the surface. Specific Na+ adsorption at the graphite basal surface causes charging of the interface in the absence of an applied potential. At moderate bulk concentrations, this leads to accumulation of counter-ions in a diffuse layer to balance the effective surface charge, consistent with established models of the electrical double layer (DL). Beyond 0.6 M, however, a combination of over-screening and ion crowding in the DL results in alternating compact layers of ion density perpendicular to the interface. The transition to this regime is marked by an increasing DL size and anomalous negative shifts to the potential of zero charge with incremental changes to the bulk concentration. Our observations are supported by changes to the position of the differential capacitance minimum measured by electrochemical impedance spectroscopy. Furthermore, a striking level of agreement between the differential capacitance from simulations and experiments allows us to critically assess the accepted norm that electrochemical capacitance measurements report simply on the density of states of the graphite material. Finally, ion crowding at the highest concentrations (beyond 5 M) leads to the formation of liquid-like NaCl clusters confined to highly non-ideal regions of the double layer, where ion diffusion is up to five times slower than in the bulk.
Planetesimal Accretion onto Growing Proto-Gas-Giant Planets

description: The solar and extra solar gas giants appear to have diverse internal structure and metallicities. We examine a potential cause for these dispersions in the context of the conventional sequential accretion formation scenario. In principle, gas accretion onto cores with masses below several times that of the Earth is suppressed by the energy released from the bombardment of residual planetesimals. We show that these planetesimals generally cannot pass through the mean motion resonances of the cores, and the suppression of planetesimal bombardment rate enables the cores to accrete gas with little interruption. During growth from the cores to protoplanets, as the resonances overlap with each other, the trapped planetesimals become dynamically unstable and their eccentricity excitation is strongly enhanced. Subsequent gas drag induces the planetesimals to migrate and collide with the protoplanet. This process leads to the resumption and a surge of planetesimal bombardment during the advanced stage of the protoplanet growth. This mechanism may account for the diversity of the core-envelope structure between Jupiter, Saturn and the metallicity dispersion inferred from the transiting extra solar planets.

description: We propose a novel design with a nano-patterned metallic layer embedded in the front window of an
ultra-thin a-Si:H solar cell. Broadband light trapping is achieved under both light polarizations for a structure with a
one-dimensional silver grating placed above the active layer. Losses in the metal are kept low over the visible range.
The silver grating is also used as a front contact, allowing us to replace the conventional indium tin oxide layer by a
non-absorbing material thereby reducing the absorption losses at short wavelengths. A theoretical short-circuit
current of 14.6 mA/cm2 is predicted for a 90 nm-thick a-Si:H absorber layer. This multi-resonant approach has been
experimentally validated with the fabrication and optical characterization of solar cells with an ultra-thin a-Si:H
absorber layer.
The D^4 R^4 term in type IIB string theory on T^2 and U-duality

description: We propose a manifestly U-duality invariant modular form for the D^4 R^4 interaction in type IIB string theory compactified on T^2. It receives perturbative contributions upto two loops, and non-perturbative contributions from D-instantons and (p,q) string instantons wrapping T^2. We provide evidence for this modular form by showing that the coefficients at tree level and at one loop precisely match those obtained using string perturbation theory. Using duality, parts of the perturbative amplitude are also shown to match exactly the results obtained from eleven dimensional supergravity compactified on T^3 at one loop. Decompactifying the theory to nine dimensions, we obtain a U-duality invariant modular form, whose coefficients at tree level and at one loop agree with string perturbation theory.

description: We investigate the interaction effects in the stellar and gas kinematics, stellar population and ionized gas properties in the interacting galaxy pair AM1209-292, composed by NGC4105 and NGC4106. The data consist of long-slit spectra in the range of 3000-7050 Å. The massive E3 galaxy NGC4105 presents a flat stellar velocity profile, while the ionized gas is in strong rotation, suggesting external origin. Its companion, NGC4106, shows asymmetries in the radial velocity field, likely due to the interaction. The dynamics of the interacting pair was modeled using P-Gadget3 TreePM/SPH code, from which we show that the system has just passed the first perigalacticum, which triggered an outbreak of star formation, currently at full maximum. We characterized the stellar population properties using the stellar population synthesis code STARLIGHT and, on average, both galaxies are predominantly composed of old stellar populations. NGC4105 has a slightly negative age gradient, comparable to that of the most massive elliptical galaxies, but a steeper metallicity gradient. The SB0 galaxy NGC4106 presents smaller radial variations in both age and metallicity in comparison with intermediate mass early-type galaxies. These gradients have not been disturbed by the interaction since the star formation happened very recently and was not extensive in mass. Electron density estimates for the pair are systematically higher than those obtained in isolated galaxies. The central O/H abundances were obtained from photoionization models in combination with emission line ratios, which resulted in 12+log(O/H)=9.03+/-0.02 and 12+log(O/H)=8.69+/-0.05 for NGC4105 and NGC4106, respectively.

description: The long term stability highly influences the total power output of a PV module over its lifetime which
is the most important factor of a PV system. Delaminations and discoloration are only two examples for encapsulant
degradation. Therefore PV module manufacturers have to monitor EVA’s degree of cross-linking which usually the
solvent extraction method (Soxhlet) is been used for. Unfortunately this inaccurate method needs several days to get a result and a chemical laboratory is necessary. Finding a rapid but accurate method to determine the degree of crosslinking
and to observe the curing characteristics of EVA is the objective of this present work. Among chemical
analyzing methods, e.g. Soxhlet extraction, there are other methods like Dynamic Mechanical Analysis (DMA) and
Differential Scanning Calorimetry (DSC). DMA is the most suitable method because the cross-linking process
influences the mechanical properties of polymers and it observes the changes by measuring the resultant torque. For
excellent results a cure meter is recommended because of the enclosed test chamber. The paper results show, that the
cure meter is able to identify the curing characteristics of EVA based encapsulants. It is useful to implement this
method into the incoming goods inspection of curing materials like EVA as well as developing lamination cycles in
process engineering.

description: Machine learning has achieved an important role in the automatic classification of variable stars, and several classifiers have been proposed over the last decade. These classifiers have achieved impressive performance in several astronomical catalogues. However, some scientific articles have also shown that the training data therein contain multiple sources of bias. Hence, the performance of those classifiers on objects not belonging to the training data is uncertain, potentially resulting in the selection of incorrect models. Besides, it gives rise to the deployment of misleading classifiers. An example of the latter is the creation of open-source labelled catalogues with biased predictions. In this paper, we develop a method based on an informative marginal likelihood to evaluate variable star classifiers. We collect deterministic rules that are based on physical descriptors of RR Lyrae stars, and then, to mitigate the biases, we introduce those rules into the marginal likelihood estimation. We perform experiments with a set of Bayesian Logistic Regressions, which are trained to classify RR Lyraes, and we found that our method outperforms traditional non-informative cross-validation strategies, even when penalized models are assessed. Our methodology provides a more rigorous alternative to assess machine learning models using astronomical knowledge. From this approach, applications to other classes of variable stars and algorithmic improvements can be developed.

description: Amorphous silicon oxynitride (a-SiOxNy:H) films, which are deposited by plasma enhanced chemical
vapor deposition (PECVD) at low temperatures (Tdep < 200°C), are investigated in terms of their electrical, optical, and
structural properties. The purpose is to develop a passivation layer for crystalline silicon solar cells, which is comparable
to amorphous silicon (a-Si:H) films in terms of manufacturing process and passivation quality, but superior to a-Si:H
films in terms of parasitic absorption. In comparison to a-Si:H films, amorphous silicon oxynitride films suffer less from
parasitic absorption over the whole wavelength range due to their higher optical band gap (Eg). The widening of the
optical band gap is realized by the incorporation of oxygen and nitrogen atoms in the amorphous network. Ongoing with
the incorporation of oxygen and nitrogen atoms is the possibility to tune the refractive index (n) in a certain range, which
turns amorphous silicon oxynitride into a very interesting material for solar cell applications, in particular for
heterojunction solar cells and multilayer anti reflection coatings.
QCD corrections to t\bar t b \bar b productions via photon-photon collisions at linear colliders

description: We calculated the complete next-to-leading order(NLO) QCD corrections to the $t\bar t b \bar b$ production process at a $γγ$ collider in the standard model(SM). The calculation of the one-loop QCD correction includes the evaluations of the hexagon and pentagon amplitudes. We studied the NLO QCD corrected total cross section, the distributions of transverse momenta of final top- and bottom-quark states, and the dependence of the cross section on renormalization scale $μ$. It shows that NLO QCD correction generally increases the LO cross section in our chosen parameter space, and the K-factor varies from 1.70 to 1.14 when colliding energy goes up from $400 GeV$ to $2 TeV$. We find that the correction distinctly changes the distributions of transverse momenta of the final top- and bottom-quark states, and the NLO QCD correction obviously improves the independence of the cross section for process $γγ\to t\bar t b\bar b$ on the renormalization scale.

description: Thin-film photovoltaic (PV) module production is expected to continue growing in importance among
the total PV production capacity in the near future. More than half the companies working nowadays on thin-film PV
modules is focusing on a-Si based technologies, among which the multi-junction structures have demonstrated
laboratory efficiencies above 10%. Multi-junction devices present several challenges in the development of dedicated
measurement procedures. Among those, the measurement of the spectral response of large area modules has been
investigated recently. Several solutions have been found since the 1990s to overtake the small-size monochromatic
beam limitation: some of those are briefly revised. The authors also present a newly developed setup based on a large
area pulsed solar simulator with bandpass filters to produce the uniform monochromatic beam and with powerful
LED floodlight to allow current-limitation from the component junction under investigation. Examples of
measurements with a variety of multi-junction commercial modules are presented.

description: We construct new examples of immersed minimal surfaces with catenoid ends and finite total curvature, of both genus zero and higher genus. In the genus zero case, we classify all such surfaces with at most $2n+1$ ends, and with symmetry group the natural $\bfZ_2$ extension of the dihedral group $D_n$. The surfaces are constructed by proving existence of the conjugate surfaces. We extend this method to cases where the conjugate surface of the fundamental piece is noncompact and is not a graph over a convex plane domain.
Quantum contribution to magnetotransport in weak magnetic fields and negative longitudinal magnetoresistance

description: Longitudinal magnetoresistance (LMR) refers to the change in resistance due to a magnetic field when the current and the magnetic field are parallel to each other. For this to be nonzero in weak magnetic fields, kinetic theory stipulates that the electronic dispersion must satisfy certain conditions: it should either be sufficiently anisotropic or have topological features. The former results in a positive LMR, while the latter results in a negative LMR. Here, I propose a different mechanism that leads to LMR in any dispersion without a need to satisfy the above requirements. The mechanism is quantum in origin but is applicable in the said regime. It arises due to the change in the density of states with the magnetic field and is not kinetic in origin. Remarkably, LMR is found to be negative even if the dispersion is nontopological, provided it is nonparabolic. An analytical expression is derived for this contribution to LMR. It is found to depend on the orbital magnetic susceptibility. The analytical findings are confirmed by numerical calculations.

description: The operation of a nuclear power station powering Deep Space transport is presented in the paper. The power station consists of a Gas Core Reactor (GCR) with magnetohydrodynamic (MHD) generator. A new model of gas core reactor which has advantages by comparison with known models is suggested. It is shown that $200\ ton$ system would generate $200\ MW$ electricity. The gas core reactor consists of a spherical cavity of $1\ m$ to $1.5\ m$ radius surrounded by a $50\ cm$ thick liquid beryllium reflector within molybdenum--92 container. The fuel consists of $^{235}$UF$_4$, KF, and K. It is demonstrated that such power station will work for gaseous fuel pressures of $50\ atm$ to $100\ atm$. The Monte-Carlo simulations describing paths of thousands of neutrons are performed. These simulations yield neutronic results, i.e. the fractions of neutrons causing fission, being absorbed by moderator, and escaping the reactor. From this information one can calculate minimum needed pressure inside the reactor, the reactor size, and moderator thickness. The conductivity of superheated fuel depending on temperature and pressure is also calculated. It is concluded that space propulsion is the best use of uranium resources.

description: The role of surface analysis, specifically XPS (X-ray Photoelectron Spectroscopy) and ToF-SIMS
(Time-of-Flight Secondary Ion Mass Spectrometry) has been explored to broaden our understanding of ZnO
TCO/encapsulant interactions focusing on TCO resistivity evolution. Peel laminates of PVB, ionomer and EVA
encapsulants with LPCVD boron doped ZnO coated glass were exposed to damp heat and removed at different points
in the aging cycle for analysis. In this study, the transition from a cohesive peel within the encapsulant toward an
adhesive peel between the TCO/encapsulant layers as defined by XPS provided an important point of comparison for
the encapsulants under evaluation. Trends in interfacial ion enrichment as a function of damp heat exposure were also
determined with a combination of XPS and ToF-SIMS to provide the necessary quantitation, sensitivity and surface
specificity. Depth profiling to determine the distribution of mobile species throughout the thickness of the TCO added
another dimension to our understanding of TCO/encapsulant interactions and their effect on TCO resistivity.
