description: The suffering of godly men and the prosperity of the wicked often become the struggle for faithful men. This issue has been around for all ages, from the biblical times until today. This struggle could have implications for the faith of the believers within one’s life. Therefore the sound understanding of God and His will through the scripture is needed. Psalm 73 is one of the Bible texts that is talking about this important issue. Through a pure biblical qualitative study with literal-grammatical-historical-contextual interpretation and exegesis theory approach, and also considering the literature style of the Psalm it is found that the base of the struggle from the existence of prosperity among the wicked is the problem from the heart. An envious heart toward the wealthiness of the wicked often moved the faith of the godly men about the kindness of the Lord. But when believers have an intimate relationship with the Lord, then new perspectives will be opened by God concerning the struggle. God is sovereign towards men’s life. The end of the wicked lives has been determined. On the contrary, for those who live in faith, the presence of God is the highest goodness because the life of a believer along with the Lord with him will always be under His nurture.

Penderitaan orang benar dan kemakmuran orang fasik seringkali menjadi pergumulan bagi orang yang beriman. Isu ini sesungguhnya ada sepanjang zaman yaitu sejak zaman Alkitab hingga masa kini.Pergumulan ini dapat berimplikasi kepada iman orang percaya di tengah kehidupannya. Oleh sebab itu diperlukan pemahaman yang benar tentang Allah dan kehendak-Nya melalui kebenaran firman-Nya. Mazmur 73 adalah salah satu teks Alkitab yang membicarakan tentang isu penting ini. Melalui studi kualitatif kajian biblika murni dengan pendekatan teori tafsir literal-gramatikal-historikal-kontekstual dan eksegesis, serta dengan mempertimbangkan bentuk sastra dari Mazmur didapatkan pemahaman bahwa masalah hati merupakan dasar dari munculnya pergumulan tentang kemakmuran orang fasik. Hati yang cemburu terhadap kemakmuran orang fasik seringkali menggoyahkan keyakinan orang beriman akan kebaikan Allah. Tetapi ketika orang beriman memiliki persekutuan yang intim dengan Allah, maka ada perspektif baru yang akan dibukakan oleh Allah tentang pergumulannya. Sesungguhnya Allah berdaulat atas hidup manusia. Akhir hidup orang fasik sudah ditentukan. Tetapi bagi orang beriman, penyertaan Tuhan adalah kebaikan yang tertinggi karena dengan penyertaan Tuhan hidup orang beriman akan selalu dalam pemeliharaan-Nya.

description: This paper describes a general approach for stochastic modeling of assets returns and liability cash-flows of a typical pensions insurer. On the asset side, we model the investment returns on equities and various classes of fixed-income instruments including short- and long-maturity fixed-rate bonds as well as index-linked and corporate bonds. On the liability side, the risks are driven by future mortality developments as well as price and wage inflation. All the risk factors are modeled as a multivariate stochastic process that captures the dynamics and the dependencies across different risk factors. The model is easy to interpret and to calibrate to both historical data and to forecasts or expert views concerning the future. The simple structure of the model allows for efficient computations. The construction of a million scenarios takes only a few minutes on a personal computer. The approach is illustrated with an asset-liability analysis of a defined benefit pension fund.

description: We investigate the possibility of generating initial conditions for cosmological N-body simulations by simulating a system whose correlations at thermal equilibrium approximate well those of cosmological density perturbations. The system is an appropriately modified version of the standard ``one component plasma'' (OCP). We show first how a well-known semi-analytic method can be used to determine the potential required to produce the desired correlations, and then verify our results for some cosmological type spectra with simulations of the full molecular dynamics. The advantage of the method, compared to the standard one, is that it gives by construction an accurate representation of both the real and reciprocal space correlation properties of the theoretical model. Furthermore the distributions are also statistically homogeneous and isotropic. We discuss briefly the modifications needed to implement the method to produce configurations appropriate for large N-body simulations in cosmology, and also the generation of initial velocities in this context.

Sequences of Bubbles and Holes: New Phases of Kaluza-Klein Black Holes

description: We construct and analyze a large class of exact five- and six-dimensional regular and static solutions of the vacuum Einstein equations. These solutions describe sequences of Kaluza-Klein bubbles and black holes, placed alternately so that the black holes are held apart by the bubbles. Asymptotically the solutions are Minkowski-space times a circle, i.e. Kaluza-Klein space, so they are part of the (μ,n) phase diagram introduced in hep-th/0309116. In particular, they occupy a hitherto unexplored region of the phase diagram, since their relative tension exceeds that of the uniform black string. The solutions contain bubbles and black holes of various topologies, including six-dimensional black holes with ring topology S^3 x S^1 and tuboid topology S^2 x S^1 x S^1. The bubbles support the S^1's of the horizons against gravitational collapse. We find two maps between solutions, one that relates five- and six-dimensional solutions, and another that relates solutions in the same dimension by interchanging bubbles and black holes. To illustrate the richness of the phase structure and the non-uniqueness in the (μ,n) phase diagram, we consider in detail particular examples of the general class of solutions.

description: In this work, we investigate the size, thermal inertia, surface roughness and geometric albedo of 10 Vesta family asteroids by using the Advanced Thermophysical Model (ATPM), based on the thermal infrared data acquired by mainly NASA's Wide-field Infrared Survey Explorer (WISE). Here we show that the average thermal inertia and geometric albedo of the investigated Vesta family members are 42 $\rm J m^{-2} s^{-1/2} K^{-1}$ and 0.314, respectively, where the derived effective diameters are less than 10 km. Moreover, the family members have a relatively low roughness fraction on their surfaces. The similarity in thermal inertia and geometric albedo among the V-type Vesta family member may reveal their close connection in the origin and evolution. As the fragments of the cratering event of Vesta, the family members may have undergone similar evolution process, thereby leading to very close thermal properties. Finally, we estimate their regolith grain sizes with different volume filling factors.

Effectiveness of the 5-TODAY program at increasing fruit and vegetable consumption in grade five and six children
Creators: name: House, Jennifer
Publisher: name: University of British Columbia
Year: 2009

description: Adequate fruit and vegetable (FV) intake may help prevent chronic disease, yet most Canadians do not consume the recommended minimum five servings per day. The 5-TODAY project targeted children to promote FV intake. The purpose of this study was to evaluate the effectiveness of the 5-TODAY program in grade five and six students. Specific objectives were to measure changes in FV intake and knowledge, attitudes and perceptions regarding FVs„ and to identify ways in which the 5-TODAY program could be improved. Evaluation the 5-TODAY program, involved 10 Vancouver area schools, divided into three intervention levels: liaison, champion and usual practice. Grade five and six class teachers in intervention schools taught students about FVs, using provided 5-TODAY lesson plans. Quantitative assessment of the 5-TODAY program included 24-hour food recalls, FV food frequency questionnaires (FFQ), and a FV Knowledge, Attitudes & Perceptions (KAP) survey. The students completed these three forms before, during, and after 5-TODAY implementation. Qualitative evaluation involved the use of focus groups with the teachers who implemented the program. Repeated measures ANOVA results of the 24-hour food recall and FFQ showed that total FV intake did not increase significantly during the duration of the 5-TODAY program. The KAP survey revealed that the students' attitudes towards FVs did not change as a result of the 5- TODAY program. Teachers thought the 5-TODAY program increased awareness of the importance of FV in students, teachers and schools. Some teachers felt that their students did not change their eating behaviour during 5-TODAY implementation, while other teachers did observe changes, although some only temporary. Suggestions to improve the program included increased time and intensity, as well as targeting a younger age group. Results show that the average FV intake of the sample (3.49 servings/day) did not meet the recommended minimum amount of five FVs per day at any measurement period. Also, 75% of students consumed less than five FV daily. This provides evidence that further FV promotion interventions are required in Canadian elementary schools. To achieve success, it is recommended that these programs include multiple dimensions, such as classroom, environmental, community and parental components.

description: In this paper a NARMA L2, model reference and neural network predictive controller is utilized in order to control the output flow rate of the steam in furnace by controlling the steam flow valve. The steam flow control system is basically a feedback control system which is mostly used in cement production industries. The design of the system with the proposed controllers is done with Matlab/Simulink toolbox. The system is designed for the actual steam flow output to track the desired steam that is given to the system as input for two desired steam input signals (step and sine wave). In order to analyze the performance of the system, comparison of the proposed controllers is done by simulating the system for the two reference signals for the system with and without sensor noise disturbance. Finally the comparison results prove the effectiveness of the presented process control system with model reference controller.

Using Birman-Schwinger principle we show that the discrete spectrum of such an operator is nonempty if the potential well defining the channel profile is deep and narrow enough. Some related problems are also mentioned.

Moreover they well evidence changes in the states of a dynamical system. We recall their features and give practical recipes. It is shown that RP and RQA detect the critical regime in financial indices (in analogy with phase transition) before a bubble bursts, whence allowing to estimate the bubble initial time. The analysis is made on DAX and NASDAQ daily closing price between Jan. 1998 and Nov. 2003. DAX is studied in order to set-up overall considerations, and as a support for deducing technical rules. The NASDAQ bubble initial time has been estimated to be on Oct. 19, 1999.

description: We study the $α+ α+ {}^{3}$He cluster structure of ${}^{11}$C within the microscopic cluster model. The calculations essentially reproduce the energy spectra for both negative and positive parity states, particularly the $3/2_3^-$ state near the $α+α$+${}^{3}$He threshold. We also calculate the isoscalar monopole, electric quadrupole transition strengths, and root-mean-square radii for the low-lying states. These results suggest that the $3/2_3^-$, $1/2_2^-$, and $5/2_3^-$ states have a well-developed $α+ α$ + ${}^{3}$He cluster structure. The analysis of the generator coordinate method wave functions indicates the dilute gaslike nature for the $3/2_3^-$, $1/2_2^-$, and $5/2_3^-$ states, suggesting that they could be candidates for the Hoyle-analog state. Furthermore, it is found that the $5/2_2^+$ and $5/2_3^+$ states may possess a linear chain structure.

description: We report the first detection of a planetary-mass companion to a star using the High Resolution Spectrograph (HRS) of the Hobby-Eberly Telescope (HET). The HET-HRS now gives routine radial velocity precision of 2-3 m/s for high SNR observations of quiescent stars. The planetary-mass companion to the metal-rich K0V star HD37605 has an orbital period of 54.23 days, an orbital eccentricity of 0.737, and a minimum mass of 2.84 Jupiter masses. The queue-scheduled operation of the Hobby-Eberly Telescope enabled us to discovery of this relatively short-period planet with a total observation time span of just two orbital periods. The ability of queue-scheduled large-aperture telescopes to respond quickly to interesting and important results demonstrates the power of this new approach in searching for extra-solar planets as well as in other ares of research requiring rapid response time critical observations.

description: This article presents the characterization of analog and digital control loops using PID and PIDN control algorithms for bidirectional buck and boost converter (BBC). Control loops of BBC are designed and implemented in MATLAB code using transfer functions in time domain with unit step response and in frequency domain with bode plots and pole-zero plots. These transfer functions are obtained by average large signal modeling of BBC. Actions of analog and digital control loops are characterized in order to ensure stability and dynamic response of BBC which is a bottleneck in renewable energy applications. Improvement in dynamic response and stability of BBC with PIDN control algorithm is demonstrated using bode plots, pole-zero plots, and step response. Control loop gain due to transfer functions of power stage and controllers is demonstrated, and it is found stable in both analog and digital control loops. PIDN compensator is proposed to maintain a healthy balance between the stability and transient behavior since both are indirectly proportional. BBC is modeled using average large signal modeling technique, simulated using MATLAB tool, and analysis of dynamic and stability response is done through unit step input, bode plot, and pole-zero plot. Hardware is designed and implemented using TMS320F28335 controller.

We develop a theoretical framework for analyzing pseudo-random ensembles generated through a random circuit composition. We prove that the measure over random circuits converges exponentially (with increasing circuit length) to the uniform (Haar) measure on the unitary group and describe how the rate of convergence may be calculated for specific applications.

description: In this work we study the convergence properties of the one-level parallel Schwarz method with Robin transmission conditions applied to the one-dimensional and two-dimensional Helmholtz and Maxwell's equations. One-level methods are not scalable in general. However, it has recently been proven that when impedance transmission conditions are used in the case of the algorithm applied to the equations with absorption, under certain assumptions, scalability can be achieved and no coarse space is required. We show here that this result is also true for the iterative version of the method at the continuous level for strip-wise decompositions into subdomains that can typically be encountered when solving wave-guide problems. The convergence proof relies on the particular block Toeplitz structure of the global iteration matrix. Although non-Hermitian, we prove that its limiting spectrum has a near identical form to that of a Hermitian matrix of the same structure. We illustrate our results with numerical experiments.

description: Observations of AGNs and microquasars by ASCA, RXTE, Chandra and XMM-Newton indicate the existence of broad X-ray emission lines of ionized heavy elements in their spectra. Such spectral lines were discovered also in X-ray spectra of neutron stars and X-ray afterglows of GRBs. Recently, Zakharov et al. (MNRAS, 2003, 342, 1325) described a procedure to estimate an upper limit of the magnetic fields in regions from which X-ray photons are emitted. The authors simulated typical profiles of the iron $K_α$ line in the presence of magnetic field and compared them with observational data in the framework of the widely accepted accretion disk model. Here we further consider typical Zeeman splitting in the framework of a model of non-flat accretion flows, which is a generalization of previous consideration into non-equatorial plane motion of particles emitting X-ray photons. Using perspective facilities of space borne instruments (e.g. Constellation-X mission) a better resolution of the blue peak structure of iron $K_α$ line will allow to evaluate the magnetic fields with higher accuracy.

description: We present a new approach to the Helmholtz spectrum for arbitrarily shaped boundaries and general boundary conditions. We derive the boundary induced change of the density of states in terms of the free Green's function from which we obtain non-perturbative results for the Casimir interaction between rigid surfaces. As an example, we compute the lateral electrodynamic force between two corrugated surfaces over a wide parameter range. Universal behavior, fixed only by the largest wavelength component of the surface shape, is identified at large surface separations, complementing known short distance expansions which we also reproduce with high precision.

description: We investigate the recent suggestions by Barausse et al. (astro-ph/0501152) and Kolb et al. (hep-th/0503117) that the acceleration of the universe could be explained by large superhorizon fluctuations generated by inflation. We show that no acceleration can be produced by this mechanism. We begin by showing how the application of Raychaudhuri equation to inhomogeneous cosmologies results in several ``no go'' theorems for accelerated expansion. Next we derive an exact solution for a specific case of initial perturbations, for which application of the Kolb et al. expressions leads to an acceleration, while the exact solution reveals that no acceleration is present. We show that the discrepancy can be traced to higher order terms that were dropped in the Kolb et al. analysis. We proceed with the analysis of initial value formulation of general relativity to argue that causality severely limits what observable effects can be derived from superhorizon perturbations. By constructing a Riemann normal coordinate system on initial slice we show that no infrared divergence terms arise in this coordinate system. Thus any divergences found previously can be eliminated by a local rescaling of coordinates and are unobservable. We perform an explicit analysis of the variance of the deceleration parameter for the case of single field inflation using usual coordinates and show that the infrared divergent terms found by Barausse et al. and Kolb et al. cancel against several additional terms not considered in their analysis. Finally, we argue that introducing isocurvature perturbations does not alter our conclusion that the accelerating expansion of the universe cannot be explained by superhorizon modes.

description: Background and aim: Acute-on-chronic liver failure (ACLF) is characterized by the presence of acute decompensation (AD) of cirrhosis, organ failures, and high short-term mortality rates. In present study, we explored whether Pro-adrenomedullin (Pro-ADM), a biomarker of sepsis, is a potential marker of outcome in patients admitted for AD or ACLF and whether it might be of additional value to conventional prognostic scoring systems in these patients. Methods: 332 consecutive patients with AD of cirrhosis were prospectively enrolled. Pro-ADM was measured for all patients at baseline. Cox regression analysis was used to evaluate the impact of pro-ADM on short-term survival and developing ACLF during hospital stay. Results: Serum pro-ADM levels were significantly high in non-survivors (p r = 0.181, p = .001), INR (r = 0.144, p = .009), TB (r = 0.368, p r = 0.145, p = .004), MELD score (r = 0.334, p = r = 0.375, p= Conclusions: Serum pro-ADM levels correlate with multiorgan failure and are independently associated with short-term survival and ACLF development in patients admitted for AD or ACLF.

description: We present a gigabit transceiver prototype Application Specific Integrated Circuit (ASIC), GBCR, for the ATLAS Inner Tracker (ITk) Pixel detector readout upgrade. GBCR is designed in a 65-nm CMOS technology and consists of four upstream receiver channels, a downstream transmitter channel, and an Inter-Integrated Circuit (I2C) slave. The upstream channels receive the data at 5.12 Gbps passing through 5-meter 34-American Wire Gauge (AWG) Twin-axial (Twinax) cables, equalize them, retime them with a recovered clock, and then drive an optical transmitter. The downstream channel receives the data at 2.56 Gbps from an optical receiver and drives the cable as same as the upstream channels. The jitter of the upstream channel output is measured to be 35 ps (peak-peak) when the Clock-Data Recovery (CDR) module is turned on and the jitter of the downstream channel output after the cable is 138 ps (peak-peak). The power consumption of each upstream channel is 72 mW when the CDR module is turned on and the downstream channel consumes 27 mW. GBCR survives the total ionizing dose of 200 kGy.

description: One strategy for developing glycoside hydrolase (GH) inhibitors is to mimic the conformation of the transition state (TS) along the hydrolysis reaction coordinate. We present a DFT-based model to understand the conformational space of the oxocarbenium cation as a TS in carbohydrate chemistry. Using Bolzano’s theorem, we have demonstrated the existence of a function that divides the puckering coordinate space. These results are compared with the available experimental crystal structures of GH-inhibitor complexes, and a contradictory case (GH92) was computationally studied. Our mathematical model opens a door to design more specific inhibitors and to decipher the catalytic pathways of controversial cases.

description: Nassella neesiana (Chilean needle grass), an invasive ‘sleeper weed’ established in sheep and beef pastures in three of New Zealand’s sixteen local government regions, has a potential geographic range amounting to 3.96 million hectares spanning all regions except the West Coast. It impacts the productivity, market value and welfare of livestock through its sharp penetrating that cause blindness and the downgrading of wool, hides, and carcasses. In this study we estimate the benefit of preventing its spread as the present value (PV) of local (regional) and national productivity losses that would accrue over 200 years under a ‘do nothing’ spread scenario. Using a 3% discount rate and two assumed spread rates, 201 and 100 years to 90% occupation of its potential range, we calculate national PV losses of NZ$ 192 million and NZ$ 1,160 million respectively. In a breakeven analysis, these losses, which equate to the national benefits of preventing the spread, justify annual expenditures of NZ$ 5.3 million and NZ$ 34 million respectively. Restricting the analyses to the regions with known infestations (Hawke’s Bay, Marlborough, Canterbury) provided much lower estimates of the benefits (ranging from NZ$ 16.8 million to NZ$ 158 million) because spillover benefits from preventing spread to the other susceptible regions are not accounted for. These analyses support a nationally coordinated approach to managing N. neesiana in New Zealand involving surveillance and control measures respectively in the susceptible and infested regions.

description: The influence of surface anisotropy on the magnetization processes of maghemite nanoparticles with ellipsoidal shape is studied by means of Monte Carlo simulations. Radial surface anisotropy is found to favor the formation of hedgehog-like spin structures that become more stable as the surface anisotropy constant at the surface $k_S$ is increased form the value at the core. We have studied the change in the low temperature hysteresis loops with the particle aspect ratio and with $k_S$, finding a change in the magnetization reversal mode as $k_S$ or the particle elongation is increased.

description: A facial-parity edge-coloring of a $2$-edge-connected plane graph is a facially-proper edge-coloring in which every face is incident with zero or an odd number of edges of each color. A facial-parity vertex-coloring of a $2$-connected plane graph is a facially-proper vertex-coloring in which every face is incident with zero or an odd number of vertices of each color. Czap and Jendroľ (in Facially-constrained colorings of plane graphs: A survey, Discrete Math. 340 (2017), 2691--2703), conjectured that $10$ colors suffice in both colorings. We present an infinite family of counterexamples to both conjectures. A facial $(P_{k}, P_{\ell})$-WORM coloring of a plane graph $G$ is a coloring of the vertices such that $G$ contains no rainbow facial $k$-path and no monochromatic facial $\ell$-path. Czap, Jendroľ and Valiska (in WORM colorings of planar graphs, Discuss. Math. Graph Theory 37 (2017), 353--368), proved that for any integer $n\ge 12$ there exists a connected plane graph on $n$ vertices, with maximum degree at least $6$, having no facial $(P_{3},P_{3})$-WORM coloring. They also asked if there exists a graph with maximum degree $4$ having the same property. We prove that for any integer $n\ge 18$, there exists a connected plane graph, with maximum degree $4$, with no facial $(P_{3},P_{3})$-WORM coloring.

description: On the basis of recent results extending non-trivially the Poincaré symmetry, we investigate the properties of bosonic multiplets including $2-$form gauge fields. Invariant free Lagrangians are explicitly built which involve possibly $3-$ and $4-$form fields. We also study in detail the interplay between this symmetry and a U(1) gauge symmetry, and in particular the implications of the automatic gauge-fixing of the latter associated to a residual gauge invariance, as well as the absence of self-interaction terms.

Calibration of proprioception
Creators: name: Bernier, Pierre-Michel
Publisher: name: University of British Columbia
Year: 2009

description: Although proprioceptive information allows accurate perception of limb movement in the absence of vision, its exact contribution to position coding when vision is also available is still debated (Gandevia et al, 1992). One view is that proprioceptive input would play a relatively minor role when vision is present (Hay et al., 1963). In fact, some have suggested that the processing and calibration of proprioceptive feedback would be masked by the processing of visual feedback (Tremblay and Proteau, 1998). The purpose of this thesis was to use a visuomotor adaptation paradigm to assess whether proprioception is concurrently calibrated with vision during visually guided movements. In Experiment 1, a full vision group (FV) was given vision of a cursor representing hand position and was asked to aim towards visible targets.' A no vision group (NV) performed the same task without vision of the cursor and was given knowledge of results (KR) after movement completion. A visual bias was introduced between the location of the cursor and the location of the hand in an adaptation phase, which resulted in participants deviating to the right of the intended target. Of interest was whether participants would still show rightward deviations in a post-test series of trials in which vision was removed (i.e. aftereffects). The NV group presented strong aftereffects. However, the FV group only showed modest aftereffects early in the post-test, which rapidly decayed over the course of the post-test. This suggests that proprioception was not calibrated when vision was concurrently available, and further analyses showed that the presence of those early aftereffects was rather due to an offline influence of vision on movement planning. A similar protocol was used in Experiment 2, but instead of inducing a visual bias, a sensory conflict was rather created through distortion of the proprioceptive sense by means of tendon vibration. Participants were asked to release two fingers at a specific target angle while the right elbow was passively extended. The vibration created a discrepancy between the proprioceptively perceived and visually perceived location of the effector. In an adaptation phase, participants performed with full vision (FV group), or with only terminal KR (NV group) while being vibrated on every trial. Any recalibration of the sensory modalities would be expressed by the presence of significant overshooting following the removal of visual feedback and vibration in a post-test phase (i.e. aftereffects). Both groups showed aftereffects early in the post-test, but these decayed very quickly, such that participants rapidly resorted to their pre-exposure levels. We propose that a sensory recalibration took place for both groups, but that the passive nature of the task prevented persistent aftereffects from occurring.

description: We report the results from spectroscopic observations of the multiple images of the strongly lensed Type Ia supernova (SN Ia), iPTF16geu, obtained with ground based telescopes and the Hubble Space Telescope (HST). From a single epoch of slitless spectroscopy with HST, we can resolve spectra of individual lensed supernova images for the first time. This allows us to perform an independent measurement of the time-delay between the two brightest images, $Δt = 1.4 \pm 5.0$ days, which is consistent with the time-delay measured from the light-curves. We also present measurements of narrow emission and absorption lines characterizing the interstellar medium in the host galaxy at z=0.4087, as well as in the foreground lensing galaxy at z=0.2163. We detect strong Na ID absorption in the host galaxy, indicating that iPTF16geu belongs to a subclass of SNe Ia displaying "anomalously" large Na ID column densities in comparison to the amount of dust extinction derived from their light curves. For the deflecting galaxy, we refine the measurement of the velocity dispersion, $σ= 129 \pm 4$ km/s, which significantly constrains the lens model. Since the time-delay between the SN images is negligible, we can use unresolved ground based spectroscopy, boosted by a factor ~70 from lensing magnification, to study the properties of a high-z SN Ia with unprecedented signal-to-noise ratio. The spectral properties of the supernova, such as pseudo-Equivalent widths of several absorption features and velocities of the Si II-line indicate that iPTF16geu, besides being lensed, is a normal SN Ia, indistinguishable from well-studied ones in the local universe, providing support for the use of SNe Ia in precision cosmology. We do not detect any significant deviations of the SN spectral energy distribution from microlensing of the SN photosphere by stars and compact objects in the lensing galaxy.

Aspects of a new class of braid matrices: roots of unity and hyperelliptic $q$ for triangularity, L-algebra,link-invariants, noncommutative spaces

description: Various properties of a class of braid matrices, presented before, are studied considering $N^2 \times N^2 (N=3,4,...)$ vector representations for two subclasses. For $q=1$ the matrices are nontrivial. Triangularity $(\hat R^2 =I)$ corresponds to polynomial equations for $q$, the solutions ranging from roots of unity to hyperelliptic functions. The algebras of $L-$ operators are studied. As a crucial feature one obtains $2N$ central, group-like, homogenous quadratic functions of $L_{ij}$ constrained to equality among themselves by the $RLL$ equations. They are studied in detail for $N =3$ and are proportional to $I$ for the fundamental $3\times3$ representation and hence for all iterated coproducts. The implications are analysed through a detailed study of the $9\times 9$ representation for N=3. The Turaev construction for link invariants is adapted to our class. A skein relation is obtained. Noncommutative spaces associated to our class of $\hat R$ are constructed. The transfer matrix map is implemented, with the N=3 case as example, for an iterated construction of noncommutative coordinates starting from an $(N-1)$ dimensional commutative base space. Further possibilities, such as multistate statistical models, are indicated.
