description: Das Ziel dieser In-vitro-Studie war es, die Auswirkungen des Herstellungsverfahrens von Bohrschablonen auf die dreidimensionale Übertragungsgenauigkeit der Implantatposition zu untersuchen. Verglichen wurden 3D-gedruckte (3DF), gefräste (FF) und laborgefertigte Orientierungsschablonen (LO).
 Material und Methoden: Die Implantatposition in Regio 026 wurde virtuell in einem Prüfmodell geplant. Zur räumlichen Erfassung wurden sieben Glaskugeln in das virtuelle Modell konstruiert. Da diese gewählte Referenzmethode zur Vermessung der Prüfmodelle neuartig und noch nicht dokumentiert worden war, wurde eine Eignungs- und Reproduzierbarkeitsüberprüfung durchgeführt. Die 3DF- und FF- Führungsschablonen wurden virtuell entworfen, während die LO- Orientierungsschablonen manuell erstellt wurden. Es wurden 10 Bohrschablonen je Herstellungsverfahren angefertigt (3DF, FF und LO). Jede Bohrschablone wurde für eine schablonengeführte Implantatinsertion in einem 3D- gedruckten Prüfmodell verwendet, die im gleichen Phantomkopf fixiert wurden. Zur Auswertung der Implantatposition wurden von allen 30 Prüfmodellen DVT-Aufnahmen angefertigt, in einer 3D-Software überlagert und die Implantatpositionen bestimmt. Gemessen wurden die Abweichungen an der Implantatschulter und Implantatapex in den drei Raumrichtungen (x,y,z), die Abweichungen im Raum (dxyz), sowie die Winkelabweichungen.
 Ergebnisse: Höchste horizontale Abweichungen an der Implantatschulter vestibulo-oral 0,17 mm (FF und LO) und mesio-distal 0,37 mm (L0). Höchste Werte am vestibulo-oralen Apex 0,45 mm (3DF) und mesio-distal 0,77 mm (L0). Die höchste maximale Abweichung betrug 1,23 mm (LO). Die vertikalen Abweichungen lagen zwischen 0,93 mm (FF) und 1,02 mm (3DF) an der Implantatschulter und zwischen 0,98 mm (3DF) und 1,04 mm (3DF) am Implantat-Apex. Die höchste maximale Abweichung wurde mit 1,29 mm (3DF) gemessen. Die Winkelabweichungen lagen zwischen 2,3° (max. 4,2°) für 3DF und 3,4° (max. 5,3°) für FF.
 Schlussfolgerungen: Die Studie zeigt, dass eine hohe und zuverlässige Übertragungsgenauigkeit innerhalb des erforderlichen Sicherheitsbereichs von 1,5 mm und 2,0 mm erreicht werden konnte. Es wurden keine signifikanten Unterschiede in der Übertragungsgenauigkeit zwischen den verwendeten Bohrschablonen festgestellt.

description: Data from a long time evolution experiment with Escherichia Coli and from a large study on copy number variations in subjects with european ancestry are analyzed in order to argue that mutations can be described as Levy flights in the mutation space. These Levy flights have at least two components: random single-base substitutions and large DNA rearrangements. From the data, we get estimations for the time rates of both events and the size distribution function of large rearrangements.

description: We consider the generalization of the Navier-Stokes equations from $\mathbb R^n$ to the Riemannian manifolds. There are inequivalent formulations of the Navier-Stokes equations on manifolds due to the different possibilities for the Laplacian operator acting on vector fields on a Riemannian manifold. We present several distinct arguments that indicate that the form of the equations proposed by Ebin and Marsden in 1970 should be adopted as the correct generalization of the Navier-Stokes to the Riemannian manifolds.

description: In these introductory lectures, we review the theoretical tools used in constructing supersymmetric field theories and their application to physical models. We first introduce the technology of two-component spinors, which is convenient for describing spin-$1/2$ fermions. After motivating why a theory of nature may be supersymmetric at the TeV energy scale, we show how supersymmetry (SUSY) arises as an extension of the Poincaré algebra of spacetime symmetries. We then obtain the representations of the SUSY algebra and discuss its simplest realization in the Wess-Zumino model. In order to have a systematic approach for obtaining supersymmetric Lagrangians, we introduce the formalism of superspace and superfields and recover the Wess-Zumino Lagrangian. These methods are then extended to encompass supersymmetric abelian and non-abelian gauge theories coupled to supermatter. Since supersymmetry is not an exact symmetry of nature, it must ultimately be broken. We discuss several mechanisms of SUSY-breaking (both spontaneous and explicit) and briefly survey various proposals for realizing SUSY-breaking in nature. Finally, we construct the the Minimal Supersymmetric extension of the Standard Model (MSSM), and consider the implications for the future of SUSY in particle physics.

description: Nanosecond pulsed electric fields are able to manipulate internal cell organelles by taking advantage of the small but finite time required for charge to establish across a capacitive barrier. Pulsed electric fields also affect macromolecular structures such as enzymes and proteins. Application of a single nanosecond pulsed electric field decreases the fluorescence of a commercially available biological dye Bodipy FL C5 Ceramide, used to observe the Golgi apparatus of living cells. The effect is seen when the fluorophore is exposed to an electric field both in vitro and when incorporated into the Golgi of a living Jurkat cell. Observation with a laser scanning confocal microscope provides high resolution thin slices for analysis. This indicates it may be possible to alter the structure and function of other biologically significant molecules both in vitro and in situ for a variety of applications. No changes in the gross morphology of the Golgi were observed after cells or dye was exposed to the electric field.

description: One important aspect at the sustainable urban planning is the reserve of green spaces into various scales, due to the fact that they possess multiple purposes, reducing the pollution and contributing to the physical, social and psychological health of the users and the community that frequent those spaces. The replacement of the green areas for impermeable areas contributes, between other effects, for the floods and the heat of the urban surface, generating the heat island effect. The objective of this paper was to quantify the spatial distribution of the arboreal vegetation on the campus of the University of Passo Fundo, through geoprocessing techniques, correlating with the arboreal specimens existing, on the intention of comprehend its relation with the environmental sustainability and implications to the users of the campus. To quantify the spatial distribution of the arboreal vegetation were obtained images of high resolution from satellite, for the quantification was utilized the group of softwares ArcGIS 10.2, through the supervised classification technique, which classifies the original image into classes based on a number of samples. The area was classified inside of four distinct classes, arboreal formation, undergrowth, buildings/roads and water resources. Besides that, were evaluated the arboreal species present on the campus through the forest inventory. Were found over 102 different arboreal species with about 4100 specimens, being distributed in the whole area of the campus, this way favoring the benefits they bring, influencing on the microclimate and raising the air humidity through the evapotranspiration, providing an more favorable environment to the users, and allowing that the waters resulting from the precipitation infiltrate in the soil mitigating the rapid runoff, which is one of the factors that aggravate the formation of floods and spates. The vegetations are one important piece for the people that live and use the artificial ambient, avoiding the decline on the urban life quality and contributing at the sustainability. Because of that, there is the need to plan those artificial ambient, creating alternatives from the vegetations so that the users of these environments do not suffer the consequences of the lack of planning.

description: Accurate MR-based attenuation correction (MRAC) is essential for quantitative PET/MR imaging of the brain. In this study, we analyze the regional bias caused by MRAC based on Zero-Echo-Time MR images (ZTEAC) compared to CT-based AC (CTAC) in static and dynamic PET imaging. In addition the results are compared to the performance of the current default Atlas-based AC (AtlasAC) implemented in the GE SIGNA PET/MR. Methods: Thirty static [18F]FDG and 11 dynamic [18}F]PE2I acquisitions from a GE SIGNA PET/MR were reconstructed using ZTEAC (using a research tool, GE Healthcare), single-subject AtlasAC (the current default AC in GE's SIGNA PET/MR) and CTAC (from a PET/CT acquisition of the same day). In the 30 static [18F]FDG reconstructions, the bias caused by ZTEAC and AtlasAC in the mean uptake of 85 anatomical volumes of interest (VOIs) of the Hammers' atlas was analyzed in PMOD. For the 11 dynamic [18}F]PE2I reconstructions, the bias caused by ZTEAC and AtlasAC in the non displaceable binding potential BPnd in the striatum was calculated with cerebellum as the reference region and a simplified reference tissue model. Results: The regional bias caused by ZTEAC in the static [18F]FDG reconstructions ranged from -8.0% to +7.7% (mean 0.1%, SD 2.0%). For AtlasAC this bias ranged from -31.6% to +16.6% (mean -0.4%, SD 4.3%). The bias caused by AtlasAC showed a clear gradient in the cranio-caudal direction (-4.2% in the cerebellum, +6.6% in the left superior frontal gyrus). The bias in the striatal BPnd for the [18F]PE2I reconstructions ranged from -0.8% to +4.8% (mean 1.5%, SD 1.4%) using ZTEAC and from -0.6% to +9.4% using AtlasAC (mean 4.2%, SD 2.6%). Conclusion: ZTEAC provides excellent quantitative accuracy for static and dynamic brain PET/MR, comparable to CTAC, and is clearly superior to the default AtlasAC currently implemented in the GE SIGNA PET/MR.

description: Matrix-valued measures provide a natural language for the theory of finite rank perturbations. In this paper we use this language to prove some new perturbation theoretic results. Our main result is a generalization of the Aronszajn--Donoghue theorem about the mutual singularity of the singular parts of the spectrum for rank one perturbations to the case of finite rank perturbations. Simple direct sum type examples indicate that an exact generalization is not possible. However, in this paper we introduce the notion of \emph{vector mutual singularity} for the matrix-valued measures and show that if we use this notion, the mutual singularity still holds for the finite rank perturbations. As for the scalar spectral measures and the classical mutual singularity, we show that the singular parts are mutually singular for almost all perturbations. One of the ways to prove that is to use a generalization of the Aleksandrov's spectral averaging to the matrix-valued measures, which is also one of the main results of this paper. Finally, the spectral representation of the perturbed operator is obtained. The matrix Muckenhoupt $A_2$ condition appears naturally there, and it plays an important role in establishing the vector mutual singularity of the spectral measures.

description: How can engineering students be prepared for their career in the 21st century? For over 10 years, Engineers Without Borders Canada (EWB) has advanced the concept of the ‘global engineer’ as one approach to this challenge. The global engineer is a technically competent engineer with excellent communication and leadership skills, as well as a developed awareness of globalization and sustainability. The current engineering curriculum offers many tools and resources to prepare students for the unique challenges and opportunities that the 21st century will present. However, there is a great opportunity to leverage recent advances in online learning and network/community based learning to enable students to further connect to these 21st century concepts. This paper outlines the architecture of an online platform as well as its approach to pedagogy and developing a Canadian learning network for global engineering.
The Responsibility Quantification (ResQu) Model of Human Interaction with Automation

description: Intelligent systems and advanced automation are involved in information collection and evaluation, in decision-making and in the implementation of chosen actions. In such systems, human responsibility becomes equivocal. Understanding human casual responsibility is particularly important when intelligent autonomous systems can harm people, as with autonomous vehicles or, most notably, with autonomous weapon systems (AWS). Using Information Theory, we develop a responsibility quantification (ResQu) model of human involvement in intelligent automated systems and demonstrate its applications on decisions regarding AWS. The analysis reveals that human comparative responsibility to outcomes is often low, even when major functions are allocated to the human. Thus, broadly stated policies of keeping humans in the loop and having meaningful human control are misleading and cannot truly direct decisions on how to involve humans in intelligent systems and advanced automation. The current model is an initial step in the complex goal to create a comprehensive responsibility model, that will enable quantification of human causal responsibility. It assumes stationarity, full knowledge regarding the characteristic of the human and automation and ignores temporal aspects. Despite these limitations, it can aid in the analysis of systems designs alternatives and policy decisions regarding human responsibility in intelligent systems and advanced automation.

description: Let $p$ be a prime. A pro-$p$ group $G$ is said to be 1-smooth if it can be endowed with a homomorphism of pro-$p$ groups $G\to1+p\mathbb{Z}_p$ satisfying a formal version of Hilbert 90. By Kummer theory, maximal pro-$p$ Galois groups of fields containing a root of 1 of order $p$, together with the cyclotomic character, are 1-smooth. We prove that a finitely generated $p$-adic analytic pro-$p$ group is 1-smooth if, and only if, it occurs as the maximal pro-$p$ Galois group of a field containing a root of 1 of order $p$. This gives a positive answer to De Clerq-Florence's "Smoothness Conjecture" - which states that the Rost-Voevodsky Theorem (a.k.a. Bloch-Kato Conjecture) follows from 1-smoothness - for the class of finitely generated $p$-adic analytic pro-$p$ groups.

description: When humans interact with intelligent systems, their causal responsibility for outcomes becomes equivocal. We analyze the descriptive abilities of a newly developed responsibility quantification model (ResQu) to predict actual human responsibility and perceptions of responsibility in the interaction with intelligent systems. In two laboratory experiments, participants performed a classification task. They were aided by classification systems with different capabilities. We compared the predicted theoretical responsibility values to the actual measured responsibility participants took on and to their subjective rankings of responsibility. The model predictions were strongly correlated with both measured and subjective responsibility. A bias existed only when participants with poor classification capabilities relied less-than-optimally on a system that had superior classification capabilities and assumed higher-than-optimal responsibility. The study implies that when humans interact with advanced intelligent systems, with capabilities that greatly exceed their own, their comparative causal responsibility will be small, even if formally the human is assigned major roles. Simply putting a human into the loop does not assure that the human will meaningfully contribute to the outcomes. The results demonstrate the descriptive value of the ResQu model to predict behavior and perceptions of responsibility by considering the characteristics of the human, the intelligent system, the environment and some systematic behavioral biases. The ResQu model is a new quantitative method that can be used in system design and can guide policy and legal decisions regarding human responsibility in events involving intelligent systems.

description: We study locality preserving automorphisms of operator algebras on $D$-dimensional uniform lattices of prime $p$-dimensional qudits (QCA), specializing in those that are translation invariant (TI) and map every prime $p$-dimensional Pauli matrix to a tensor product of Pauli matrices (Clifford). We associate antihermitian forms of unit determinant over Laurent polynomial rings to TI Clifford QCA with lattice boundaries, and prove that the form determines the QCA up to Clifford circuits and shifts (trivial). It follows that every 2D TI Clifford QCA is trivial since the antihermitian form in this case is always trivial. Further, we prove that for any $D$ the fourth power of any TI Clifford QCA is trivial. We present explicit examples of nontrivial TI Clifford QCA for $D=3$ and any odd prime $p$, and show that the Witt group of the finite field $\mathbb F_p$ is a subgroup of the group $\mathfrak C(D = 3, p)$ of all TI Clifford QCA modulo trivial ones. That is, $\mathfrak C(D = 3, p \equiv 1 \mod 4) \supseteq \mathbb Z_2 \times \mathbb Z_2$ and $\mathfrak C(D = 3, p \equiv 3 \mod 4) \supseteq \mathbb Z_4$. The examples are found by disentangling the ground state of a commuting Pauli Hamiltonian which is constructed by coupling layers of prime dimensional toric codes such that an exposed surface has an anomalous topological order that is not realizable by commuting Pauli Hamiltonians strictly in two dimensions. In an appendix independent of the main body of the paper, we revisit a recent theorem of Freedman and Hastings that any two-dimensional QCA, which is not necessarily Clifford or translation invariant, is a constant depth quantum circuit followed by a shift. We give a more direct proof of the theorem without using any ancillas.

description: Quantum computers promise to perform computations beyond the reach of modern computers with profound implications for scientific research. Due to remarkable technological advances, small scale devices are now becoming available for use. One of the most apparent applications for such a device is the study of complex many-body quantum systems, where classical computers are unable to deal with the generic exponential complexity of quantum states. Even zero-temperature equilibrium phases of matter and the transitions between them have yet to be fully classified, with topologically protected phases presenting major difficulties. We construct and measure a continuously parametrized family of states crossing a symmetry protected topological phase transition on the IBM Q quantum computers. We present two complementary methods for measuring string order parameters that reveal the transition, and additionally analyse the effects of noise in the device using simple error models. The simulation that we perform is easily scalable and is a practical demonstration of the utility of near-term quantum computers for the study of quantum phases of matter and their transitions.

description: Understanding how genotypes map onto phenotypes, fitness, and eventually organisms is arguably the next major missing piece in a fully predictive theory of evolution. We refer to this generally as the problem of the genotype-phenotype map. Though we are still far from achieving a complete picture of these relationships, our current understanding of simpler questions, such as the structure induced in the space of genotypes by sequences mapped to molecular structures, has revealed important facts that deeply affect the dynamical description of evolutionary processes. Empirical evidence supporting the fundamental relevance of features such as phenotypic bias is mounting as well, while the synthesis of conceptual and experimental progress leads to questioning current assumptions on the nature of evolutionary dynamics-cancer progression models or synthetic biology approaches being notable examples. This work delves into a critical and constructive attitude in our current knowledge of how genotypes map onto molecular phenotypes and organismal functions, and discusses theoretical and empirical avenues to broaden and improve this comprehension. As a final goal, this community should aim at deriving an updated picture of evolutionary processes soundly relying on the structural properties of genotype spaces, as revealed by modern techniques of molecular and functional analysis.

description: No, they can't. Epidemic spread is characterized by exponentially growing dynamics, which are intrinsically unpredictable. The time at which the growth in the number of infected individuals halts and starts decreasing cannot be calculated with certainty before the turning point is actually attained; neither can the end of the epidemic after the turning point. An SIR model with confinement (SCIR) illustrates how lockdown measures inhibit infection spread only above a threshold that we calculate. The existence of that threshold has major effects in predictability: A Bayesian fit to the COVID-19 pandemic in Spain shows that a slow-down in the number of newly infected individuals during the expansion phase allows to infer neither the precise position of the maximum nor whether the measures taken will bring the propagation to the inhibition regime. There is a short horizon for reliable prediction, followed by a dispersion of the possible trajectories that grows extremely fast. The impossibility to predict in the mid-term is not due to wrong or incomplete data, since it persists in error-free, synthetically produced data sets, and does not necessarily improve by using larger data sets. Our study warns against precise forecasts of the evolution of epidemics based on mean-field, effective or phenomenological models, and supports that only probabilities of different outcomes can be confidently given.

description: This study was conducted to clarify the bioactive activities of red kohlrabi sprouts(Brassica oleracea L. var. gongylodes L.), which were produced using the smart farm and drum-type rotary facilities arranged in a row. We have harvested red kohlrabi  sprout vegetables at 6 days after germination which were sprouted at 20℃. Roots were harvested at 90 days after seedling, which were fresh weight 752g/ea. Samples were freeze drying to analyse the bioactive components. We have also examined the bioactive activity of sprouts and roots of kohlrabi after extracting with methanol. Total phenol and flavonoid contents of red kohlrabi sprouts increased significantly more than two times than those of roots. Antioxidant enzyme activity of red kohlrabi sprouts such as SOD, CAT, APX and POD also increased remarkably compared with that of roots. DPPH radical scavenging activity and ABTS radical scavenging activity of red kohlrabi sprouts were higher than those of roots. However, there were lower anti-cancer activities of sprouts against Calu-6 and MCF-7 cell lines than those of roots.  Key-words : Kohlrabi, sprout, polyphenol, flavonoid, antioxidation, bioactive activity  This study was conducted under the supply of "Korea Small and Medium Business Administration(C0353901)".

description: Two types of preservation methods based on the ultra high temperature (UHT) and microwave (MW) technologies were used for pasteurisation of cloudy juices prepared from different varieties of apples. The technological trials using Vaculiq press for juice production under anaerobic conditions and  EnbioJet microwave flow pasteurizer or UHT system were performed in order to evaluate the effect of preservation method on the stability of phenolic compounds in apple juice. The chemical properties verified embraced determinations of polyphenols by HPLC-DAD-MS, total antioxidant activity, as well as chromatographic profiling of antioxidants by HPLC post-column derivatization. The obtained results indicate that the degradation of phenolic compounds during MW and UHT preservation processes was in the range 20-32% and 7-18%, respectively. As a consequence, the reduction of antioxidant activity at the level of 12-39% and 10-28% for MW and UHT technologies was observed. The results also revealed a significant effect of apple variety on the changes in polyphenolic profile due to the pasteurization process. Our studies could be of use while selecting the proper technology of preservation to maximize stability of apple phytochemicals and thereby to enhance the healthiness of diet for human populations.

description: In vitro cultures of sage (Salvia officinalis) were established by culturing internodal segments, excised from aseptic seedlings, on MS basal medium gellied with agar and supplemented with an auxin and a citokinin. Calli were induced and maintained with 2,4-dichlorophenoxyacetic acid (2,4-D) in presence of benzyladenine (BA) or zeatin (ZEA) or kinetin (KIN). Suspended cells were established by transferring one callus to liquid MS basal medium devoid of agar and containing the same type of hormonal supplementation used in respective calli growth. Good suspensions majority constituted by single cells and microcalli were formed with an auxin (2,4-Dichlorophenoxyacetic acid) and a citokinin (kinetin). Under these conditions, the suspended sage cells biomass grow showed a doubling time lower than 4 days depending on the initial cell density and age of the culture. The phenolics, produced sage calli and suspended cells were extracted from with acetone and methanol and were analysed and identified by HPLC-DAD. Twelve phenolic compounds were identified in calli: gallic acid, 3-O caffeoylquinic acid, 5-O-caffeoylquinic acid, caffeic acid, rosmarinic acid, hesperetin, epirosmanol, hispidulin, genkwanin, carnosol, carnosic acid, and methyl carnosate. With the exception for genkwanin and epirosmanol all of these phenolic compounds were also produced by the sage suspension cultures grown.

What do programme chairs think about the integration of SD in their programmes?

description: This paper presents the findings of interviews with six engineering programme chairs regarding their views about the level of integration of SD in their programmes. They are part of a wider study which is examining the integration of SD in engineering programmes across three Irish Higher Education Institutions. Previous stages of the study have determined that students’ knowledge and understanding about SD is inadequate due to the lack of a holistic integration of SD competencies and the focus on skills development in their programmes. The paper will explore the apparent contradiction in that most programme chairs believe that SD is integrated into their programmes despite the evidence from the previous stages of this project which suggest it is not. This contradiction can only be resolved by an exploration of their understanding of SD and their philosophy of engineering education. We conclude that they believe SD is fully integrated because they have a narrow understanding of SD and a “traditional” approach to engineering focused on the development of core engineering competencies.

description: Polyphenols are a class of compounds derived from the secondary metabolism in plants. They are present in many natural products, namely fruits, vegetables, wines, amongst others.
The growing interest in studying polyphenols relies in the evidence that they possess a high number of protective biologic properties including antioxidant, anti-inflammatory, antibacterial and anticarcinogenic activities. Such compounds are capable of scavenging free radicals, which can oxidize biological macromolecules (DNA,proteins and lipids) in cells and tissues. The purpose of this study was to investigate the effect of red wine bioactive compounds (resveratrol, catechin and quercetin) on cell growth of human colonic adenocarcinoma (Caco-2) cells. The effect from the combination of polyphenols together with the action of cisplatin was also tested. Cell viability was measured using the mitochondrial metabolic rate throughMTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) reduction assay. The half maximal inhibitory concentration (IC50) values from different combinations were also calculated.

description: The classical Aronszajn-Donoghue theorem states that for a rank one perturbation of a self-adjoint operator (by a cyclic vector) the singular parts of the spectral measures of the original and perturbed operators are mutually singular. As simple direct sum type examples show, this result does not hold for finite rank perturbations. However, the set of exceptional perturbations is pretty small. Namely, for a family of rank $d$ perturbations $A_{\boldsymbolα} := A +\mathbf{B} \boldsymbolα \mathbf{B}^*$, $\mathbf{B}:\mathbb{C}^d\to \mathbf{H}$, with Ran$\,\mathbf{B}$ being cyclic for $A$, parametrized by $d\times d$ Hermitian matrices $\boldsymbolα$, the singular parts of the spectral measures of $A$ and $A_{\boldsymbolα}$ are mutually singular for all $\boldsymbolα$ except for a small exceptional set $E$. It was shown earlier by the first two authors that $E$ is a subset of measure zero of the space $\mathbf{H}(d)$ of $d\times d$ Hermitian matrices. In this paper we show that the set $E$ has small Hausdorff dimension, $\dim E \le \dim\mathbf{H}(d)-1 = d^2-1$.

Lepton flavor violations in SUSY models for muon $g-2$ with right-handed neutrinos

description: We consider supersymmetric (SUSY) models for the muon $g-2$ anomaly without flavor violating masses at the tree-level. The models can avoid LHC constraints and the vacuum stability constraint in the stau-Higgs potential. Although large flavor violating processes are not induced within the framework of minimal SUSY standard model, once we adopt a seesaw model, sizable lepton flavor violating (LFV) processes such as $μ\to e γ$ and $μ\to e$ conversion are induced. These LFV processes will be observed at future experiments such as MEG-II, COMET and Mu2e if right-handed neutrinos are heavier than $10^9$ GeV motivated by the successful leptogenesis. This conclusion is somewhat model independent since Higgs doublets are required to have large soft SUSY breaking masses, leading to flavor violations in a slepton sector via neutrino Yukawa interactions.

description: In vitro cultured Salvia lavandulifolia seedlings were obtained from bleach surface sterilized seeds on solid MS medium devoid of growth regulators. Shoot cultures were maintained by culturing nodal segments excised from the in vitro growing seedlings on the same renewed MS medium supplemented with an auxin, a cytokinin and a gibberellin. S. lavandulifolia calli and suspended cells were obtained from leaves of in vitro growing shoots cultured on solid and liquid MS medium, respectively, both devoid of gibberellin but supplemented with an auxin and a cytokinin. Methanolic extracts were obtained from the freeze-dried biomass of in vivo growing plants and from the three kind of in vitro cultures. The phenolic diterpenes represented the major group of the constituents of in the methanolic extracts of in vivo plants and in vitro growing shoots. However the phenolic diterpenes in calli were detected only in trace amounts and in suspended cells they were apparently absent. In counterpart the four phenolic acids detected constituted the major phenolic group in suspended cells and calli, being also present in shoots as the second major group, while in in vivo plants only trace amounts of p-cumaric acid was detected.

description: In this paper, a simple yet effective network pruning framework is proposed to simultaneously address the problems of pruning indicator, pruning ratio, and efficiency constraint. This paper argues that the pruning decision should depend on the convolutional weights, and thus proposes novel weight-dependent gates (W-Gates) to learn the information from filter weights and obtain binary gates to prune or keep the filters automatically. To prune the network under efficiency constraints, a switchable Efficiency Module is constructed to predict the hardware latency or FLOPs of candidate pruned networks. Combined with the proposed Efficiency Module, W-Gates can perform filter pruning in an efficiency-aware manner and achieve a compact network with a better accuracy-efficiency trade-off. We have demonstrated the effectiveness of the proposed method on ResNet34, ResNet50, and MobileNet V2, respectively achieving up to 1.33/1.28/1.1 higher Top-1 accuracy with lower hardware latency on ImageNet. Compared with state-of-the-art methods, W-Gates also achieves superior performance.
