Evaluation of the proximal adductor canal block injectate spread: a cadaveric study
Authors: Tran John , Chan Vincent W S , Peng Philip W H , Agur Anne M R 
Published: December 2019

Background and objectives
Quadriceps sparing adductor canal block has emerged as a viable intervention to manage pain after total knee arthroplasty. Recent studies have defined ultrasound (US) landmarks to localize the proximal and distal adductor canal. US-guided proximal adductor canal injection has not been investigated using these sonographic landmarks. The objectives of this cadaveric study were to evaluate dye injectate spread and quantify the capture rates of nerves supplying articular branches to the knee joint capsule using a proximal adductor canal injection technique.

Methods
A US-guided proximal adductor canal injection with 10 mL of dye was performed in seven lightly embalmed specimens. Following injection, specimens were dissected to document dye spread and frequency of nerve staining.

Results
Following proximal adductor canal injection, dye spread consistently stained the deep surface of sartorius, vastoadductor membrane, aponeurosis of the vastus medialis obliquus, and adductor canal. The saphenous nerve, posteromedial branch of nerve to vastus medialis, superior medial genicular nerve and genicular branch of obturator nerve were captured in all specimens at the proximal adductor canal. There was minimal to no dye spread to the distal femoral triangle, anterior division of the obturator nerve and anterior branches of nerve to vastus medialis.

Conclusions
This anatomical study provides some insights into the mechanism of analgesia to the knee following a proximal adductor canal injection and its motor sparing properties. Further clinical investigation is required to confirm cadaveric findings.

AbstractIn this work, we present the first experimental upper limits on the presence of stochastic gravitational waves in a frequency band with frequencies above 1 THz. We exclude gravitational waves in the frequency bands from$$\left( 2.7 - 14\right) \times 10^{14}$$2.7-14×1014Hz and$$\left( 5 - 12\right) \times 10^{18}$$5-12×1018 Hz down to a characteristic amplitude of$$h_c^{\mathrm{min}}\approx 6\times 10^{-26}$$hcmin≈6×10-26and$$h_c^{\mathrm{min}}\approx 5\times 10^{-28}$$hcmin≈5×10-28at 95% confidence level, respectively. To obtain these results, we used data from existing facilities that have been constructed and operated with the aim of detecting weakly interacting slim particles, pointing out that these facilities are also sensitive to gravitational waves by graviton to photon conversion in the presence of a magnetic field. The principle applies to all experiments of this kind, with prospects of constraining (or detecting), for example, gravitational waves from light primordial black-hole evaporation in the early universe.
Similarity solutions for the Wheeler–DeWitt equation in $$f\left( R\right) $$-cosmology
Authors: Paliathanasis Andronikos 
Published: December 2019

AbstractIn the case of a spatially flat Friedmann–Lemaître–Robertson–Walker Universe in $$f\left( R\right) $$fR-gravity we write the Wheeler–DeWitt equation of quantum cosmology. The equation depends upon the functional form of $$f\left( R\right) $$fR. We choose to work with four specific functions of $$f\left( R\right) $$fR in which the field equations for the classical models are integrable and solvable through quadratures. For these models we determine similarity solutions for the Wheeler–DeWitt equation by determining Lie–Bäcklund transformations. In addition we show how the classical limit is recovered by the similarity solutions of the Wheeler–DeWitt equation.

Published: December 2019

Deep Neural Networks (DNNs) are now increasingly adopted in a variety of Artificial Intelligence (AI) applications. Meantime, more and more DNNs are moving from cloud to the mobile devices, as emerging AI chips are integrated into mobiles. Therefore, the DNN models can be deployed in the cloud, on the mobile devices, or even mobile-cloud coordinate processing, making it a big challenge to select an optimal deployment strategy under specific objectives.
This article proposes a DNN tuning framework, i.e., DNNTune, that can provide layer-wise behavior analysis across a number of platforms. Using DNNTune, this article further selects 13 representative DNN models, including CNN, LSTM, and MLP, and three mobile devices ranging from low-end to high-end, and two AI accelerator chips to characterize the DNN models on these devices to further assist users finding opportunities for mobile-cloud coordinate computing. Our experimental results demonstrate that DNNTune can find a coordinated deployment achieving up to 1.66× speedup and 15× energy saving comparing with mobile-only and cloud-only deployment.
Compiler-support for Critical Data Persistence in NVM

Published: December 2019

Non-volatile Main Memories (NVMs) offer a promising way to preserve data persistence and enable computation recovery in case of failure. While the use of NVMs can significantly reduce the overhead of failure recovery, which is the case with High-Performance Computing (HPC) kernels, rewriting existing programs or writing new applications for NVMs is non-trivial. In this article, we present a compiler-support that automatically inserts complex instructions into kernels to achieve NVM data-persistence based on a simple programmer directive. Unlike checkpointing techniques that store the whole system state, our technique only persists user-designated objects as well as some parameters required for safe recovery such as loop induction variables. Also, our technique can reduce the number of data transfer operations, because our compiler coalesces consecutive memory-persisting operations into a single memory transaction per cache line when possible.
Our compiler-support is implemented in the LLVM tool-chain and introduces the necessary modifications to loop-intensive computational kernels (e.g., TMM, LU, Gauss, and FFT) to force data persistence. The experiments show that our proposed compiler-support outperforms the most recent checkpointing techniques while its performance overheads are insignificant.
Materialismo corticeiro
Authors: Campos Filho Lindberg 
Published: December 2019

Este é um breve exercício de leitura do romance emblemático do naturalismo brasileiro O cortiço (1890) de Aluísio Azevedo, levando em consideração a crítica produzida por Antonio Candido em “De cortiço a cortiço” (1974; 1991), ao mesmo tempo que levanta a hipótese de que alguns dos métodos de construção dessa narrativa podem ser lidos, em certa medida, como antecipações, ora mais ora menos conscientes, dos paradigmas de determinação social que guiariam a crítica cultural materialista ao longo do século seguinte.
As regras da subversão
Authors: Rodrigues Lidiane Soares 
Published: December 2019

O artigo trata do “Grupo 2 do Seminário sobre O Capital de Marx”, promovido por Roberto Schwarz e Ruy Fausto em 1963, assim como de sua transformação na revista Teoria e Prática. Trata-se de estabelecer os nexos entre a morfologia e a produção intelectual dos membros participantes. Considerando o perfil e as posições institucionais dos “teóricos práticos” e dos autores por eles criticados, propõe uma interpretação a respeito dos atiçamentos para a “crítica da crítica”. No interior dessa configuração, Roberto Schwarz criou uma personagem geralmente tratada de modo pouco sistemático por seus comentadores, Bertha Dunkel, demonstrando que ela encerra uma chave de leitura importante e nada anedótica.
Roberto Schwarz e a sociologia paulista dos anos 1960
Authors: Helayel Karim , Brasil Junior Antonio 
Published: December 2019

O artigo apresenta a hipótese de que, ao identificar a “volubilidade” como princípio formal do romance Memórias póstumas de Brás Cubas, de Machado de Assis, Roberto Schwarz estaria se posicionando frente às divergências entre Maria Sylvia de Carvalho Franco e Fernando Henrique Cardoso em torno da mobilização da categoria “patrimonialismo”. Localizaremos o argumento de Um mestre na periferia do capitalismo (1990), de Schwarz, diante das críticas de Franco ao uso por ela considerado improcedente da categoria “patrimonialismo” por parte de Cardoso. Discutiremos ainda as relações entre o princípio formal da “volubilidade” com a categoria “dilema”, proposta por Florestan Fernandes em seus trabalhos.

Published: December 2019

Os depósitos conglomeráticos situados nos arredores do distrito de Laras, São Paulo, capeiam colinas amplas de topo aplainado com altitudes entre 500 e 570 m. Ocorrem em discordância sobre as formações Piramboia e Teresina da Bacia do Paraná. São constituídos de fácies de ortoconglomerados polimíticos com matriz arenosa, mal selecionada. A análise de proveniência realizada evidenciou o predomínio de clastos de silexito, quartzito e quartzo de veio, bem arredondados e oblatos, sugerindo longo transporte. A análise estatística revelou maior frequência de litotipos resistentes ao transporte na porção sudeste da área. Na porção noroeste predominam clastos menos resistentes, representados por oólito e coquina, sugerindo erosão da Formação Teresina e transporte curto a partir de terrenos paleozoicos existentes na Depressão Periférica Paulista. Dados de Luminescência Opticamente Estimulada (OSL) possibilitaram conferir idade mínima de 371.4 ± 27.5 ka para a unidade. Os depósitos conglomeráticos são interpretados como produto de deposição em canais fluviais tributários de grande porte, ou mesmo de um canal tronco principal, de um extenso sistema deposicional fluvial com paleomergulho deposicional para sudoeste do Estado de São Paulo. Esse sistema fluvial antecessor do atual Rio Tietê, com proveniência de nordeste, tinha área de drenagem em terrenos pré-cambrianos situados ao leste da área de ocorrências das unidades paleozoicas. Devido à localização e ao porte, os depósitos descritos registram importante fase de agradação fluvial na história geológica do Rio Tietê, evento de sedimentação ocorrido durante o longo processo de denudação que deu origem à Depressão Periférica Paulista durante o Cenozoico.

Published: December 2019

The Botanical Survey of India launched a pilot project during 2015–2017 on exploration of orchids of Goa State covering all the protected areas. A total of 68 orchid species belonging to 28 genera were documented of which 42 are epiphytic and 26 are terrestrial. Twenty-eight species are endemic, of which 23 species are strictly endemic to the Western Ghats, two are endemic to peninsular India, and three are endemic to the country. Distribution of orchids in Goa is concentrated mainly in the Western Ghats region, which accounts for 86% of the total orchid species richness of the state. The most favourable habitat was found to be semi-evergreen forests followed by moist-deciduous forests. Among all the protected areas, the Mhadei Wildlife Sanctuary was found to be rich in orchid diversity (39 species) followed by Bhagwan Mahavir Wildlife Sanctuary, and Cotigaon Wildlife Sanctuary. The MaxEnt data shows the highly suitable area for orchids in Goa is approximately 1,005km2, which is 27% of the total geographic area of the state.

Koshi Tappu Wildlife Reserve (KTWR) has the last remaining Nepalese population of the Endangered Asiatic Wild Buffalo (Bubalus arnee Kerr, 1792). Individual animals protected inside KTWR may be of purely wild, domestic or hybrid origin, and the wild population is under potential threat due to habitat loss and genetic introgression from feral backcrosses. Identification of genetically pure wild individuals is important for identifying animals for translocation to other areas within their former range. In this study we have sequenced a highly variable 422bp region of the Cytochrome b gene of 36 animals, and added 61 published sequences of both River and Swamp Buffalo from Italy and some southern Asian countries including India. The haplotype diversities ranged from 0.286-0.589 with slightly higher diversities in domesticated individuals. The AMOVA analysis revealed that 97.217% of the genetic variation was contained within groups and 2.782% occurred among groups. An overall fixation index (FST) was found to be 0.02782 (p>0.05). Phylogenetic relationships derived through a reduced median network and maximum parsimony analyses reconfirmed the ancestral nature of the Wild Water Buffalo. Moreover, this study has reviewed recent achievements of molecular research in wild buffalo, assessed the technical capacities of research institutes in Nepal to conduct molecular research required for identifying pure wild individual in KTWR and more importantly initiated DNA bank and DNA sequence library of buffalos, which will enable an international collaboration for advanced molecular research in the future.

Published: December 2019

Objective:
Defective PC (protein C) pathway predisposes patients to venous thromboembolism (VTE) and is mostly, but not exclusively, attributed to hereditary PC or PS (protein S) deficiencies and activated PC resistance caused by factor V Leiden mutation.

Approach and Results:
In a patient with acute mesenteric venous thrombosis and positive family history of VTE associated with the impaired PC pathway function determined by thrombin generation test, we identified a novel heterozygous prothrombin mutation p.Arg541Trp. Two more patients with positive family history of VTE carrying the same mutation were identified in a cohort of another 373 unrelated patients, making an overall prevalence of 0.8%. Family investigation revealed 11 individuals in the 3 pedigrees harboring the heterozygous prothrombin p.Arg541Trp mutation, and 8 of them (72%) had experienced episodes of VTE. Functional studies indicated the mutation moderately decreased procoagulant activity of prothrombin and had mild impact on the inactivation of thrombin by its inhibitor antithrombin. However, the amino acid residue substitution significantly compromised PC activation by thrombin, both in the absence and presence of soluble thrombomodulin, and thus rendered prothrombin function procoagulant biased.

Conclusions:
In summary, the prothrombin p.Arg541Trp mutation constitutes a new genetic risk factor of VTE by impairing function of PC pathway and tilting thrombin’s procoagulant activity over anticoagulant function.
Formulation of Autoconversion and Drop Spectra Shape in Shallow Cumulus Clouds
Authors: Kogan Yefim , Ovchinnikov Mikhail 
Published: December 2019

Abstract
Two-moment autoconversion parameterizations as compared to accretion parameterizations exhibit significant errors suggesting that additional moments are needed to increase their accuracy. We develop a three-moment autoconversion parameterization using output from an LES model with size-resolved microphysics. Adding the third moment decreases the errors of parameterization and improves precipitation prediction. However, the errors are still significantly larger than errors of accretion rate. An analysis of the cloud drop size distributions (DSDs) in the simulated tropical convective cloud system reveals that most DSDs have a significant fraction of cloud liquid water content qc in the midsize droplet range (radii from 20 to 40 μm). Our data indicate that more than 30% of DSDs have over half of qc contained in the midsize range and about 60% of spectra have, at least, one-third of qc in this range. Even when the rain/drizzle mode is small (radar reflectivity Z &lt; −10 dBZ), there is a significant number of spectra in which fraction of qc in the midsize range is as large as 60%. These DSDs are more complex than the frequently used gamma or lognormal distributions, which exhibit a single mode and can be defined by three microphysical moments. The need to define DSDs by more than three moments explains the large errors in the three-moment autoconversion parameterization. The limitation of three-parameter gamma or lognormal distributions should be kept in mind when applying them in precipitating shallow cumulus clouds.
Normal Mode Spectra of Idealized Baroclinic Waves
Authors: Ambacher Matthew R. , Waite Michael L. 
Published: December 2019

AbstractNormal modes are used to investigate the contributions of geostrophic vortices and inertia–gravity waves to the energy spectrum of an idealized baroclinic wave simulation. The geostrophic and ageostrophic modal spectra (GE and AE, respectively) are compared to the rotational and divergent kinetic energy (RKE and DKE, respectively), which are often employed as proxies for vortex and wave energy. In our idealized f-plane framework, the horizontal modes are Fourier, and the vertical modes are found by solving an appropriate eigenvalue problem. For low vertical mode number n, both the GE and AE spectra are steep; however, for higher n, while both spectra are shallow, the AE is shallower than the GE and the spectra cross. The AE spectra are peaked at the Rossby deformation wavenumber knR, which increases with n. Analysis of the horizontal mode equations suggests that, for large wavenumbers k≫knR, the GE is approximated by the RKE, while the AE is approximated by the sum of the DKE and potential energy. These approximations are supported by the simulations. The vertically averaged RKE and DKE spectra are compared to the sum of the GE and AE spectra over all vertical modes; the spectral slopes of the GE and AE are close to those of the RKE and DKE, supporting the use of the Helmholtz decomposition to estimate vortices and waves in the midlatitudes. However, the AE is consistently larger than the DKE because of the contribution from the potential energy. Care must be taken when diagnosing the mesoscale transition from the intersection of the vortex and wave spectra; GE and AE will intersect at a different scale than RKE and DKE, despite their similar slopes.
Are Supercells Resistant to Entrainment because of Their Rotation?
Authors: Peters John M. , Nowotarski Christopher J. , Mullendore Gretchen L. 
Published: December 2019

AbstractThis research investigates a hypothesis posed by previous authors, which argues that the helical nature of the flow in supercell updrafts makes them more resistant to entrainment than nonsupercellular updrafts because of the suppressed turbulence in purely helical flows. It was further supposed that this entrainment resistance contributes to the steadiness and longevity of supercell updrafts. A series of idealized large-eddy simulations were run to address this idea, wherein the deep-layer shear and hodograph shape were varied, resulting in supercells in the strongly sheared runs, nonsupercells in the weakly sheared runs, and variations in the percentage of streamwise vorticity in updrafts among runs. Fourier energy spectrum analyses show well-developed inertial subranges in all simulations, which suggests that the percentages of streamwise and crosswise vorticity have little effect on turbulence in convective environments. Additional analyses find little evidence of updraft-scale centrifugally stable flow within updrafts, which has also been hypothesized to limit horizontal mass flux across supercell updrafts. Results suggest that supercells do have smaller fractional entrainment rates than nonsupercells, but these differences are consistent with theoretical dependencies of entrainment on updraft width, and with supercells being wider than nonsupercells. Thus, while supercells do experience reduced fractional entrainment rates and entrainment-driven dilution, this advantage is primarily attributable to increased supercell updraft width relative to ordinary convection, and has little to do with updraft helicity and rotation.
