Public Satisfaction Towards Land Titling Project for Agricultural Sector (a Case Study in Polewali Mandar District, West Sulawesi)

The objectives of this research are to assess the public satisfaction towards the implementation of this land titling project, and to examine to what extent the relationship between the service quality of Badan Pertanahan Nasional (BPN) and farmers satisfaction in Polewali Mandar. Finally, to recommend possible improvement for the implementation of Land titling project for agricultural sector. This study used the type of explanatory research with the quantitative approach, and focused on the agency that provide service to the public. Level of community satisfaction was used as a dependent variable. Then, as the independent variable were the assurance, cost, time and product. Research indicates that farmers are satisfied with the services provided by BPN officials through this project. The results of hypothesis tests indicate that all variables have not only simultaneously, but also partially effect towards public satisfaction Furthermore, time was the substantial one. BPN should give attention deal with cost and time factor in order to increase their service quality to public

Membrane Tension Orchestrates Rear Retraction in Matrix-Directed Cell Migration

In development, wound healing, and cancer metastasis, vertebrate cells move through 3D interstitial matrix, responding to chemical and physical guidance cues. Protrusion at the cell front has been extensively studied, but the retraction phase of the migration cycle is not well understood. Here, we show that fast-moving cells guided by matrix cues establish positive feedback control of rear retraction by sensing membrane tension. We reveal a mechanism of rear retraction in 3D matrix and durotaxis controlled by caveolae, which form in response to low membrane tension at the cell rear. Caveolae activate RhoA-ROCK1/PKN2 signaling via the RhoA guanidine nucleotide exchange factor (GEF) Ect2 to control local F-actin organization and contractility in this subcellular region and promote translocation of the cell rear. A positive feedback loop between cytoskeletal signaling and membrane tension leads to rapid retraction to complete the migration cycle in fast-moving cells, providing directional memory to drive persistent cell migration in complex matrices. © 2019 The AuthorsCell migration through 3D matrix is critical to developmental and disease processes, but the mechanisms that control rear retraction are poorly understood. Hetmanski et al. show that differential membrane tension allows caveolae to form at the rear of migrating cells and activate the contractile actin cytoskeleton to promote rapid retraction. © 2019 The Author

Combined results of searches for the standard model Higgs boson in pp collisions at root s=7 TeV

Combined results are reported from searches for the standard model Higgs boson in proton-proton collisions at root s = 7 TeV in five Higgs boson decay modes: gamma gamma, bb, tau tau, WW, and ZZ. The explored Higgs boson mass range is 110-600 GeV. The analysed data correspond to an integrated luminosity of 4.6-4.8 fb(-1). The expected excluded mass range in the absence of the standard model Higgs boson is 118-543 GeV at 95% CL. The observed results exclude the standard model Higgs boson in the mass range 127-600 GeV at 95% CL, and in the mass range 129-525 GeV at 99% CL. An excess of events above the expected standard model background is observed at the low end of the explored mass range making the observed limits weaker than expected in the absence of a signal. The largest excess, with a local significance of 3.1 sigma, is observed for a Higgs boson mass hypothesis of 124 GeV. The global significance of observing an excess with a local significance >= 3.1 sigma anywhere in the search range 110-600 (110-145) GeV is estimated to be 1.5 sigma (2.1 sigma). More data are required to ascertain the origin of the observed excess. (C) 2012 CERN. Published by Elsevier B.V. All rights reserved

Reconstruction and identification of τ lepton decays to hadrons and ντ at CMS

This paper describes the algorithms used by the CMS experiment to reconstruct and identify tau -> hadrons + nu(tau) decays during Run 1 of the LHC. The performance of the algorithms is studied in proton-proton collisions recorded at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 fb(-1). The algorithms achieve an identification efficiency of 50-60%, with misidentification rates for quark and gluon jets, electrons, and muons between per mille and per cent levels

RRM adjacent TARDBP mutations disrupt RNA binding and enhance TDP-43 proteinopathy

Amyotrophic lateral sclerosis (ALS) presents with focal muscle weakness due to motor neuron degeneration that becomes generalized,leading to death from respiratory failure within 3–5 years from symptom onset. Despite the heterogeneity of aetiology, TDP- 43 proteinopathy is a common pathological feature that is observed in 495% of ALS and tau-negative frontotemporal dementia(FTD) cases. TDP-43 is a DNA/RNA-binding protein that in ALS and FTD translocates from being predominantly nuclear to formdetergent-resistant, hyperphosphorylated aggregates in the cytoplasm of affected neurons and glia. Mutations in TARDBP accountfor 1–4% of all ALS cases and almost all arise in the low complexity C-terminal domain that does not affect RNA binding andprocessing. Here we report an ALS/FTD kindred with a novel K181E TDP-43 mutation that is located in close proximity to the RRM1 domain. To offer predictive gene testing to at-risk family members, we undertook a series of functional studies to characterizethe properties of the mutation. Spectroscopy studies of the K181E protein revealed no evidence of significant misfolding.Although it is unable to bind to or splice RNA, it forms abundant aggregates in transfected cells. We extended our study to includeother ALS-linked mutations adjacent to the RRM domains that also disrupt RNA binding and greatly enhance TDP-43 aggregation,forming detergent-resistant and hyperphosphorylated inclusions. Lastly, we demonstrate that K181E binds to, and sequesters, wild-type TDP-43 within nuclear and cytoplasmic inclusions. Thus, we demonstrate that TDP-43 mutations that disrupt RNAbinding greatly enhance aggregation and are likely to be pathogenic as they promote wild-type TDP-43 to mislocalize andaggregate acting in a dominant-negative manner. This study highlights the importance of RNA binding to maintain TDP-43solubility and the role of TDP-43 aggregation in disease pathogenesis
