TL;DR: This paper proposes a tracking system with six 6D magnetic sensors and inverse kinematics to automatically obtain 21-joints hand pose annotations of depth maps captured with minimal restriction on the range of motion, and demonstrates significant improvements in cross-benchmark performance.
Abstract: In this paper we introduce a large-scale hand pose dataset, collected using a novel capture method. Existing datasets are either generated synthetically or captured using depth sensors: synthetic datasets exhibit a certain level of appearance difference from real depth images, and real datasets are limited in quantity and coverage, mainly due to the difficulty to annotate them. We propose a tracking system with six 6D magnetic sensors and inverse kinematics to automatically obtain 21-joints hand pose annotations of depth maps captured with minimal restriction on the range of motion. The capture protocol aims to fully cover the natural hand pose space. As shown in embedding plots, the new dataset exhibits a significantly wider and denser range of hand poses compared to existing benchmarks. Current state-of-the-art methods are evaluated on the dataset, and we demonstrate significant improvements in cross-benchmark performance. We also show significant improvements in egocentric hand pose estimation with a CNN trained on the new dataset.

TL;DR: In this paper, a combined model-independent and model-dependent analysis was performed to deduce properties of new physics (NP) in b→sμ+μ-decays.
Abstract: The recent measurement of RK* is yet another hint of new physics (NP) and supports the idea that it is present in b→sμ+μ- decays. We perform a combined model-independent and model-dependent analysis in order to deduce properties of this NP. Like others, we find that the NP must obey one of two scenarios: (I) C9μμ(NP)<0 or (II) C9μμ(NP)=-C10μμ(NP)<0. A third scenario, (III) C9μμ(NP)=-C9′μμ(NP), is rejected largely because it predicts RK=1, in disagreement with experiment. The simplest NP models involve the tree-level exchange of a leptoquark (LQ) or a Z′ boson. We show that scenario II can arise in LQ or Z′ models, but scenario I is only possible with a Z′. Fits to Z′ models must take into account the additional constraints from Bs0-B¯s0 mixing and neutrino trident production. Although the LQs must be heavy, O(TeV), we find that the Z′ can be light, e.g., MZ′=10 GeV or 200 MeV.

TL;DR: In this article, a compact octagonal shaped fractal ultrawideband multiple-input-multiple-output (MIMO) antenna is presented, and its characteristics are investigated in order to achieve the desired miniaturization and wideband phenomena.
Abstract: In this letter, a compact octagonal shaped fractal ultrawideband multiple-input–multiple-output antenna is presented, and its characteristics are investigated In order to achieve the desired miniaturization and wideband phenomena, self-similar and space filling properties of Koch fractal geometry are used in the antenna design These fractal monopoles are placed orthogonal to each other for good isolation Moreover, grounded stubs are used in the geometry to provide further improvement in the isolation The band rejection phenomenon in wireless local area network band is achieved by etching a C-shaped slot from the monopole of the antenna The proposed antenna has compact dimensions of $45~\hbox{mm} \times 45~\hbox{mm}$ and exhibits quasi-omnidirectional radiation pattern In addition, it shows an impedance bandwidth ( ${{\rm S}_{11}}\! ) from 2 to 106 GHz with isolation better than 17 dB over the entire ultra-wideband range Diversity performance is also evaluated in terms of envelope correlation coefficient and capacity loss The measured results show good agreement with the simulated ones

TL;DR: This review provides topical coverage of next generation transparent conducting electrodes (TCE) based on a wide range of materials such as oxide nanoparticles, CNTs, graphene, metal nanowires, metal meshes and their hybrids.
Abstract: Heater plates or sheets that are visibly transparent have many interesting applications in optoelectronic devices such as displays, as well as in defrosting, defogging, gas sensing and point-of-care disposable devices. In recent years, there have been many advances in this area with the advent of next generation transparent conducting electrodes (TCE) based on a wide range of materials such as oxide nanoparticles, CNTs, graphene, metal nanowires, metal meshes and their hybrids. The challenge has been to obtain uniform and stable temperature distribution over large areas, fast heating and cooling rates at low enough input power yet not sacrificing the visible transmittance. This review provides topical coverage of this important research field paying due attention to all the issues mentioned above.

TL;DR: In this paper, the authors analyze all the scenarios where the new physics contributes to a pair of these operators at a time, and find that the scenarios with new physics contributions to the pair remain the most favored ones.
Abstract: The anomalies in the measurements of observables involving b → sμμ decays, namely RK, RK*, P 5 ′ , and B , may be addressed by adding lepton-universality-violating new physics contributions to the effective operators $$ {\mathcal{O}}_{\mathcal{9}},{\mathcal{O}}_{10},{\mathcal{O}}_9^{\prime },{\mathcal{O}}_{10}^{\prime } $$ . We analyze all the scenarios where the new physics contributes to a pair of these operators at a time. We perform a global fit to all relevant data in the b → s sector to estimate the corresponding new Wilson coefficients, $$ {\mathcal{O}}_9^{\mathrm{NP}},{\mathcal{O}}_{10}^{\mathrm{NP}},{\mathcal{O}}_9^{\prime },{\mathcal{O}}_{10}^{\prime } $$ . In the light of the new data on RK, and RK*, presented in Moriond 2019, we find that the scenarios with new physics contributions to the $$ \left({\mathcal{O}}_9^{\mathrm{NP}},{\mathcal{O}}_9^{\prime}\right) $$ or $$ \left({\mathcal{O}}_9^{\mathrm{NP}},{\mathcal{O}}_{10}^{\prime}\right) $$ pair remain the most favored ones. On the other hand, though the competing scenario $$ \left({\mathcal{O}}_9^{\mathrm{NP}},{\mathcal{O}}_{10}^{\mathrm{NP}}\right) $$ remains attractive, its advantage above the SM reduces significantly due to the tension that emerges between the RK and RK* measurements with the new data. The movement of the RK measurement towards unity would also result in the re-emergence of the one-parameter scenario C 9 NP = − C 9 ′ .
