Authors: Ram Sameer , Patel Jitendra , Kanani Sanjay 
Published: November 2019

Abstract
Background & Aims: The Lumbar plexus describes the origins of 4 of the nerves supplying the lower limb (femoral, lateral cutaneous nerve of the thigh, obturator and genitofemoral) along with the ilioinguinal and iliohypogastric nerves. Aim of this study is to study the abnormalities in formation of lumbar plexus and communication between the branches of lumbar plexus and its clinical implication. Material & Method: This study was conducted on 100 cadavers (67 male and 33 female) with an age range of 50 – 90 years. Results: No abnormality was found related to roots and trunk. Post fixed lumbar plexus (bilateral) were found in 6 cadavers. Genital branch and femoral branch was found to arise separately from the root in 22 cadavers (bilaterally). Accessory lateral femoral cutaneous nerve was observed on both sides in 4 cadavers. Femoral nerve was found to arise from dorsal division of L3-4-5 in 8 cadavers (bilateral). Accessory obturator nerve was found bilaterally in 26 cadavers and it was arising from L3-4. Conclusion:Knowledge of variations in the formation and branching pattem of lumbar plexus is very important during lumbar plexus block for various surgical and palliative procedures.

Published: November 2019

Abstract
Objectives This article prospectively examines the use of ultrasound for antenatal detection of abnormal placental cord insertion (PCI) and compares the antenatal classification with delivered placental classification.
Study Design This prospective cohort study examined 277 singleton pregnancies in a tertiary center. Scans were performed between 10 and 14, 18 and 22, and 32 and 34 weeks where PCI site was identified and its shortest distance to margin measured. Standardized images of delivered placentas were taken and digitally measured. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of antenatal classification compared with delivered placental classification were calculated.
Results Abnormal PCI (distance < 2 cm from margin) was confirmed in 30/277 (11%) placentas at delivery. Note that 102/277 (37%) of PCI sites were classified as abnormal in the first trimester (T1), 43/277 (16%) in the second trimester (T2), and 28/277 (10%) in the third trimester (T3). Sensitivity (73%) and specificity (91%) were highest at T2. The PPVs were low (22% in T1, 51% in T2, and 64% in T3) and the NPVs were high (96% in T1 and 97% in both T2 and T3) for all scans.
Conclusion Abnormal PCI can be detected antenatally with optimal agreement with postnatal classification in T2. However, the incidence is overestimated at early scans with low PPVs.

Published: November 2019

ABSTRACT
Lycopene is a highly valued carotenoid with wide applications in various industries. The market demand for lycopene promotes research in metabolic engineering of heterologous hosts for lycopene. In this study, Pichia pastoris strain GS115 was genetically engineered to produce lycopene by integrating the heterologous lycopene biosynthesis genes from Corynebacterium glutamicum ATCC13032. The resulting strain, L1, produced 0.115 mg/g cell dry weight (DCW) lycopene. Through optimization by promoter selection, improving the precursor supply and expanding the Geranylgeranyl diphosphate (GGPP) pool, ultimately, the lycopene yield of the final optimal strain was 6.146 mg/g DCW with shake flask fermentation and 9.319 mg/g DCW (0.714 g/L) in a 3 L fermenter. The lycopene yield in this study is the highest yield of lycopene in P. pastoris reported to date, which demonstrated the potential of P. pastoris in lycopene synthesis and as a candidate host organism for the synthesis of other high value-added terpenoids.
QCD analysis of CMS W + charm measurements at LHC with

and implications for strange PDF *
Authors: Yalkun Nijat , Dulat Sayipjamal 
Published: November 2019

Abstract
We calculate cross-sections and cross-section ratios of a charm quark production in association with a W gauge boson at next-to-leading order QCD using MadGraph and CT10NNLO, CT14NNLO, and MSTW2008NNLO PDFs. We compare the results with measurements from the CMS detector at the LHC at a center-of-mass energy of 7 TeV. Moreover, we calculate absolute and normalized differential cross-sections as well as differential cross-section ratios as a function of the lepton pseudorapidity from the W boson decay. The correlation between the CT14NNLO PDFs and predictions for

charm data are studied as well. Furthermore, by employing the error PDF updating method proposed by the CTEQ-TEA group, we update CT14NNLO PDFs, and analyze the impact of CMS 7 TeV

charm production data to the original CT14NNLO PDFs. By comparison of the

PDFs at

GeV and

GeV for the CT14NNLO and CT14NNLO+Wc, we see that the error band of the

PDF is reduced in the region

Abstract
The precision study of

production with subsequent

and

decays at the Large Hadron Collider (LHC) aids in the investigation of Higgs gauge couplings and the search for new physics beyond the standard model. In this study, we calculate the shower-matched next-to-leading order QCD and electroweak (EW) corrections from the

annihilation and photon-induced channels to the

production at the

LHC. We deal with the subsequent decays of Higgs and

bosons by adopting the MADSPIN method. Both the integrated cross section and some kinematic distributions of

, H, and their decay products are provided. We find that the QCD correction significantly enhances the leading-order differential cross section, while the EW correction from the

annihilation channel obviously suppresses it, especially in the high energy phase-space region, due to the Sudakov effect. The

- and

-induced relative corrections are positive and insensitive to the transverse momenta of

, H, and their decay products. These photon-induced corrections compensate the negative

-initiated EW correction, and become the dominant EW contribution as the increment of the

colliding energy. The parton shower (PS) effects on kinematic distributions are not negligible. The relative PS correction to the b-jet transverse momentum distribution can exceed 100% in the high

region. Moreover, we investigate the scale and PDF uncertainties, and find that the theoretical error of the

-corrected integrated cross section mainly originates from the renormalization scale dependence of the QCD correction.
Improved eikonal approach for charge exchange reactions at intermediate energies *

Published: November 2019

Abstract
In order to describe charge exchange reactions at intermediate energies, we implemented as a first step the formulation of the normal eikonal approach. The calculated differential cross-sections based on this approach deviated significantly from the conventional DWBA calculations for CE reactions at 140 MeV/nucleon. Thereafter, improvements were made in the application of the eikonal approximation so as to keep a strict three-dimensional form factor. The results obtained with the improved eikonal approach are in good agreement with the DWBA calculations and with the experimental data. Since the improved eikonal approach can be formulated in a microscopic way, it is easy to apply to CE reactions at higher energies, where the phenomenological DWBA is a priori difficult to use due to the lack, in most cases, of the required phenomenological potentials.
Constraining the anisotropy of the Universe with the Pantheon supernovae sample *
Authors: Chang Zhe , Zhao Dong , Zhou Yong 
Published: November 2019

Abstract
We test the possible dipole anisotropy of the Finslerian cosmological model and the other three dipole-modulated cosmological models, i.e. the dipole-modulated ΛCDM, wCDM and Chevallier–Polarski–Linder (CPL) models, by using the recently released Pantheon sample of SNe Ia. The Markov chain Monte Carlo (MCMC) method is used to explore the whole parameter space. We find that the dipole anisotropy is very weak in all cosmological models used. Although the dipole amplitudes of four cosmological models are consistent with zero within the

uncertainty, the dipole directions are close to the axial direction of the plane of the SDSS subsample in Pantheon. This may imply that the weak dipole anisotropy in the Pantheon sample originates from the inhomogeneous distribution of the SDSS subsample. A more homogeneous distribution of SNe Ia is necessary to constrain the cosmic anisotropy.
Free fermions with a localized source
Authors: Krapivsky P L , Mallick Kirone , Sels Dries 
Published: November 2019

Abstract
We study an open quantum system of free fermions on an infinite lattice coupled to a localized particle source. In the long time limit, the total number of fermions in the system increases linearly with growth rate dependent on the lattice geometry and dimensionality. We express the growth rate in terms of lattice Green functions and derive explicit formulae in one dimension and for the square lattice. The interplay between the dynamics and the coupling to the environment leads, in contrast to classical systems, to a non-monotonic dependence of the particle growth rate on the input rate. We show that for all lattices the particle growth rate is inversely proportional to the input rate when the latter becomes large. This is a manifestation of the quantum Zeno effect.

Published: November 2019

Abstract
This study aims to find out the indigenous knowledge of the Ciwaringin society in managing natural resources for sustainable development as an indigenous identity. The research method used in this study is a qualitative approach. Data were obtained through field observations and direct interviews with the indigenous society and five artisans. The results showed that the majority of Ciwaringin society was batik artisans who only painted batik produced in this region. In coloring process of batik, dyeing and painting techniques are used. Natural dyes are obtained from the bark, rind, and leaves that are easy to find. Indigenous knowledge is only popular among craftsmen who acquired initially from the ancestors. This coloring technique is reused by 85% of craftsmen and become a uniqueness of Ciwaringin batik. Although the production process of a sheet of batik cloth is longer than the use of synthetic dyes, it increases the selling price. Besides, this method is believed to reduce the risk of environmental pollution. This step supports the creation of sustainable development. It is hoped that the values of indigenous knowledge can be used as references and enrich scientific knowledge and become constructive thinking contributions to formulate policies of environmental management and conservation.

Abstract
The use of non-agricultural land in Universitas Pendidikan Indonesia causes the land absorption to be smaller than the use of soil for agriculture so that it can lead to surface runoff. This study discusses how to monitor rainwater infiltration to subsurface using resistivity method with Wenner’s configuration and weather data. The data retrieval takes place twice with a span of two months and is in the same place. In the model is also seen when the layer of purple rocks have decreased in volume from the first data retrieval on the second data retrieval. While the rain water infiltration layer more evenly. Monthly weather reference data showed that temperature and evapotranspiration relationships over the months showed the results from September to December were relatively stable with average temperatures of four months being 22.38 ºC and evapotranspiration was 5.02 cm / month. Therefore, the evaporation caused by all water, soil, vegetation and the earth’s surface located at the site is 5.02 cm / month. Monitoring of rainfall infiltration within two months from the first measurement having rainfall infiltration of 3.9 mm / h indicates that infiltration rate is very fast and the magnitude of evapotranspiration is 5.02 cm / month.
