Stratigraphy, Sedimentology And Tectonic Setting Of The Upper Shaler Group, Victoria Island, Northwest Territories
The stratigraphy and sedimentology of the uppermost late Proterozoic Shaler Group (Kilian and Kuujjua formations) in the Minto Inlier, Victoria Island, was investigated in order to better understand conditions of deposition and to place these strata in a regional tectonic context so that they might be compared with models developed for similar strata in adjacent and formerly adjacent areas.;Detailed stratigraphic section measurement, regional correlation and lithofacies analysis reveals that much of the upper Shaler Group was deposited on a tectonically stable, low gradient, shallow marine platform, perhaps within a passive margin or intracratonic seaway (Amundsen-Mackenzie Basin or Embayment). Subtidal to supratidal alternations (cycles) within the Kilian Formation can be correlated for at least 200 km and are attributed to two scales of glacio- and/or tectono-eustatic sea-level fluctuations. Marine deposition and cyclicity was abruptly terminated by deposition of the overlying Kuujjua Formation, a mature quartzarenite interpreted as a low sinuosity fluvial braidplain deposit, which flowed into the Amundsen Basin from the southeast. Intercalated evaporite deposits in both the Kilian and Kuujjua Formations are indicative of a prevailing arid climate.;Unimodal northwesterly paleocurrents, detrital quartz petrography, detrital zircon geochronology and mudstone geochemistry indicate that the river(s) which deposited the Kuujjua Formation may have incorporated detritus from as far away as the Grenville Province, presently 3000 km to the southeast. It also suggests that the extremely high compositional maturity of the quartzarenite may in part be due to extreme humid climate-related weathering in the source area.;Differential tectonic uplift which increased in intensity from southwest to northeast, resulting in a decrease in the rate of basin subsidence and eventual net uplift is recorded by: (1) The abrupt marine to terrestrial transition at the Kilian-Kuujjua contact, (2) pinch out of the uppermost Kilian and Kuujjua formations to the northeast, (3) block faulting and erosional preclusion of some of the uppermost Kilian Formation in the northeast part of the Minto Inlier. Uplift is considered to be a consequence of thermal upwelling which accompanied the arrival of a mantle plume at the base of the lithosphere, prior to the eruption of flood basalts of the Natkusiak Formation, uppermost stratigraphic unit of the Shaler Group
The Annales Ferdinandei of Franz Christoph of KhevenhĂĽller and Elias Wideman
The paper presents 200 newly discovered engravings for the Annales Ferdinandei by Franz Christoph of Khevenhüller from the year 1640. Many of them were made by the Augsburgian engraver Wolfgang Kilian and his company. One of the most productive cooperators of Kilian was Elias Wideman, who from 1646–1652 produced his own portrait books. It can also be proved that Khevenhüller used as models for his portraits the most recent original paintings of the imperial family and the aristocrats

Robust massive MIMO Equilization for mmWave systems with low resolution ADCs
Leveraging the available millimeter wave spectrum will be important for 5G.
In this work, we investigate the performance of digital beamforming with low
resolution ADCs based on link level simulations including channel estimation,
MIMO equalization and channel decoding. We consider the recently agreed 3GPP NR
type 1 OFDM reference signals. The comparison shows sequential DCD outperforms
MMSE-based MIMO equalization both in terms of detection performance and
complexity. We also show that the DCD based algorithm is more robust to channel
estimation errors. In contrast to the common believe we also show that the
complexity of MMSE equalization for a massive MIMO system is not dominated by
the matrix inversion but by the computation of the Gram matrix.Comment: submitted to WCNC 2018 Workshop

Measuring Half-Lives Using A Non-Parametric Bootstrap Approach
In this paper we extend the Murray and Papell (2002) study by using a non-parametric
bootstrap approach which allows for non-normality, and focusing on quarterly real
exchange rate in twenty OECD countries in the post-1973 floating period. We run
Augmented Dickey-Fuller (ADF) regressions, and estimate the half-lives (and confidence
intervals) from the corresponding impulse response functions. Further, we use an
approximately median-unbiased estimator of the autoregressive parameters, and report
the implied point estimates and confidence intervals. We find that accounting for nonnormality
results in even higher estimates of the degree of persistence of PPP deviations,
but, as in Murray and Papell (2002), the confidence intervals are so wide that no strong
conclusions are warranted on the existence of a PPP puzzle
