Structure scaling properties of confined nematic polymers in plane Couette cells: The weak flow limit

One of the confounding issues in laminar flow processing of nematic polymers is the generation of molecular orientational structures on length scales that remain poorly characterized with respect to molecular and processing control parameters. For plane Couette flow within the Leslie–Ericksen continuum model, theoretical results since the 1970s yield two fundamental predictions about the length scales of nematic distortion: a power law scaling behavior, Er−p, 14⩽p⩽1, where Er is the Ericksen number (ratio of viscous to elastic stresses); the exponent p varies according to whether the structure is a localized boundary layer or an extended structure. Until now, comparable results which incorporate molecular elasticity (i.e., distortions in the shape of the orientational distribution) have not been derived from mesoscopic Doi–Marrucci–Greco (DMG) tensor models. In this paper, we derive asymptotic, one-dimensional gap structures, along the flow-gradient direction, in “slow” Couette cells, which reflect self-consistent coupling between the primary flow, in-plane director (nematic) and order parameter (molecular) elasticity, and confinement conditions (plate speeds, gap height, and director anchoring angle). We then read off the small Deborah number, viscoelastic structure predictions: The flow is simple shear. The orientation structures consist of: two molecular-elasticity boundary layers with the Marrucci scaling Er−1/2, which are amplified by tilted plate anchoring; and a nonuniform, director-dominated structure that spans the entire gap, with Er−1 average length scale, present for any anchoring angle. We close with direct numerical simulations of the DMG steady, flow-nematic boundary-value problem, first to benchmark the small Deborah number structure formulas, and then to document onset of new flow-orientation structures as the asymptotic expansions become disordered.One of the confounding issues in laminar flow processing of nematic polymers is the generation of molecular orientational structures on length scales that remain poorly characterized with respect to molecular and processing control parameters.

Should coronary arteries with less than 60% diameter stenosis be treated by angioplasty?

We evaluated all patients receiving percutaneous transluminal coronary angioplasty (PTCA) in the past year for mild stenosis (60% or less diameter narrowing, n = 64, group 1) and compared them with a random sample of 330 patients with greater than 60% stenosis (n = 66, group 2) treated during the same year. The degree of coronary stenosis before PTCA was 52 +/- 7% (mean +/- SD) in group 1 and 79 +/- 11% in group 2. The primary success rate was 90% (58 of 64 patients) in group 1 vs 86% (57 of 66 patients) in group 2. The incidence of complications requiring coronary surgery after PTCA failed was similar in both groups (3 of 64 in group 1, 4 of 66 in group 2), but there were four occurrences of myocardial infarction in group 1 and none in group 2 (p less than .05). Recurrence of stenosis was judged on the basis of objective data, 76% of which were angiographic data, in 97% of the patients with primary success. At a mean interval of 5 months with a mean follow-up period of 7 months, 17 of 58 patients (29%) with primary success in group 1 and 24 of 57 patients (42%) in group 2 developed restenosis. In group 1, restenosis was markedly more severe (73 +/- 15%) than initial stenosis (p less than .005), which was not the case in group 2. In conclusion, PTCA in mild stenosis has favorable primary and long-term results, yet carries the risk of myocardial infarction and emergency operation and may, in some cases, even accelerate the disease process.
Alternative removal methodologies for environmental waters

The Environmental Protection Agency (EPA) continues to establish criteria for the reduction of pathogens in environmental waters used for drinking water. The EPA also states criteria on the amount of chlorine byproducts allowed in drinking water. Alternative removal methods that are used in conjunction with chlorine are needed to assure safe drinking water. The Surface Water Treatment Rule (SWTR) states that a 99.99% reduction of viruses and a 99.9% reduction in Giardia lamblia cysts needs to be achieved by a treatment facility that uses surface water for the production of drinking water. The SWTR also states Maximum Contaminant Levels (MCL) on trihalomethane production. The Groundwater Disinfection Rule (GWDR) states that a 99.99% reduction of viruses must be achieved in treatment facilities using groundwater for the production of drinking water. The ability of polysulfone hollow fiber (HF) ultrafiltration (UF) membranes to remove bacteriophage, MS2, Giardia lamblia cysts, and Cryptosporidium parvum oocysts from MilliQ water was examined. The membranes were placed in a Koch 5 bench scale disinfection unit. Operating conditions such as transmembrane pressure, pH, and temperature were varied to assess their effects on removal capability. A 100,000D PMPW membrane consistently removed 99.99% of MS2 titer and 99.999% of G. lamblia cysts and C. parvum oocysts under different operating conditions. The PMPW membrane achieved a 99.99% removal of MS2 in trials where MS2 was continually added to the influent at a concentration of $1.73\times10\sp4$ pfu/ml-min. Ultraviolet (UV) irradiation was assessed for its ability to inactivate MS2, poliovirus LSc-1, hepatitis A virus HM-175, and rotavirus Wa in bench scale petri dish assays. Known concentrations of these viruses were added to MilliQ water and different groundwaters and UV irradiated. The least susceptible virus to UV irradiation was rotavirus Wa strain. In MilliQ water and groundwater, 99.99% reductions in titer occurred at 97.0 mWs/cm$\sp2. $ A 99.99% reduction in MS2 occurred at 80 mWs/cm$\sp2$ in MilliQ water and between 64.0 mWs/cm$\sp2$ and 93.0 mWs/cm$\sp2$ in groundwaters. Poliovirus and hepatitis A virus were considerably less resistant to UV inactivation. A cell culture-RT PCR assay was used to determine rotavirus Wa titers before and after UV irradiation. Filtration was capable of meeting the pathogen removal criteria stated in the SWTR. UV irradiation met the virus inactivation criteria stated in the GWDR. Both methodologies could be used in full scale treatment plants under controlled conditions to determine their ability to remove pathogens from drinking water.
Prioritized Obstacle Avoidance in Motion Planning of Autonomous Vehicles

Driver errors are a critical factor of the majority of car crashes. Autonomous vehicles take drivers and driver errors out of the equation, so they are being developed to reduce car crashes. However, in some situations, a crash is unavoidable even for an autonomous vehicle. An autonomous vehicle is expected to behave properly in such a situation. Crashing into different obstacles have different costs based on the injury or damage the crash might cause. In an imminent crash situation, an autonomous vehicle is expected to consider these costs and plan a trajectory that avoids the obstacles with the highest priorities. In this thesis, a motion planning Model Predictive Controller (MPC) has been developed that plans the vehicle’s trajectories based on the obstacle’s priorities. Motion planning MPCs usually use potential fields or obstacle constraints for obstacle avoidance. However, they treat all the obstacles in the same way. Two methods have been developed in this thesis to prioritize obstacles in motion planning. The first method prioritizes obstacles based on their avoidance necessities. It categorizes obstacles as crossable and non-crossable, and assigns a potential function to each category corresponding to its avoidance necessity. The second method prioritizes obstacles based on their corresponding crash costs. It applies lexicographic optimization on the MPC to prioritize the non-crossable obstacles according to their crash costs by prioritizing their corresponding constraints. A motion planning MPC problem is generally a nonlinear MPC problem. It is usually approximated by a quadratic MPC problem to become implementable in real time. In this thesis, a quadratic motion planning MPC has been developed. This MPC has a linear vehicle model and linear vehicle and obstacle constraints. The linear vehicle model along with the linear vehicle constraints should be able to model the nonlinear vehicle behavior. A linear bicycle model has been utilized, and linear tire constraints have been developed such that they can model the nonlinear vehicle behavior at the tire force limits. Moreover, a linear obstacle constraint set misses some of the feasible trajectories in the process of convexifying the obstacle-free area. An iterative obstacle avoidance method has been developed in this thesis to reduce the number of feasible trajectories missed due to the convexification. The performance of the developed motion planning MPC has been evaluated in a
Spinocerebellar ataxia type 10: Frequency of epilepsy in a large sample of Brazilian patients

Spinocerebellar ataxia type 10 (SCA10) is an autosomal dominant disorder caused by an ATTCT repeat intronic expansion in the SCA10 gene. SCA 10 has been reported in Mexican, Brazilian, Argentinean and Venezuelan families. Its phenotype is overall characterized by cerebellar ataxia and epilepsy. Interestingly, Brazilian patients reported so far showed pure cerebellar ataxia, without epilepsy. Here, authors provide a systematic analysis of the presence, frequency and electroencephalographic presentation of epilepsy among 80 SCA10 patients from 10 Brazilian families. Overall, the frequency of epilepsy was considered rare, been found in 3.75 % of the cases while this finding in populations from other geographic areas reaches 60% of SCA10 cases. © 2010 Movement Disorder Society
Improving Block-level Efficiency with scsi-mq

Current generation solid-state storage devices are exposing a new bottlenecks in the SCSI and block layers of the Linux kernel, where IO throughput is limited by lock contention, inefficient interrupt handling, and poor memory locality. To address these limitations, the Linux kernel block layer underwent a major rewrite with the blk-mq project to move from a single request queue to a multi-queue model. The Linux SCSI subsystem rework to make use of this new model, known as scsi-mq, has been merged into the Linux kernel and work is underway for dm-multipath support in the upcoming Linux 4.0 kernel. These pieces were necessary to make use of the multi-queue block layer in a Lustre parallel filesystem with high availability requirements. We undertook adding support of the 3.18 kernel to Lustre with scsi-mq and dm-multipath patches to evaluate the potential of these efficiency improvements. In this paper we evaluate the block-level performance of scsi-mq with backing storage hardware representative of a HPC-targerted Lustre filesystem. Our findings show that SCSI write request latency is reduced by as much as 13.6%. Additionally, when profiling the CPU usage of our prototype Lustre filesystem, we found that CPU idle time increased by a factor of 7 with Linux 3.18 and blk-mq as compared to a standard 2.6. 32 Linux kernel. Our findings demonstrate increased efficiency of the multi-queue block layer even with disk-based caching storage arrays used in existing parallel filesystems.
Cooperative binding of Annexin A5 to phosphatidylserine on apoptotic cell membranes

Healthy cells exhibit an asymmetric plasma membrane with phosphatidylserine (PS) located on the cytoplasmic leaflet of the plasma membrane bilayer. Annexin A5-FITC, a PS binding protein, is commonly used to evaluate apoptosis in flow cytometry. PS exposed by apoptotic cells serves as a major ‘eat-me’ signal for phagocytes. Although exposition of PS has been observed after alternative stimuli, no clearance of viable, PS exposing cells has been detected. Thus, besides PS exposure, membranes of viable and apoptotic cells might exhibit specific characteristics. Here, we show that Annexin A5 binds in a cooperative manner to different types of dead cells. Shrunken apoptotic cells thereby showed the highest Hill coefficient values. Contrarily, parafomaldehyde fixation of apoptotic cells completely abrogates the cooperativity effect seen with dead and dying cells. We tend to speculate that the cooperative binding of Annexin A5 to the membranes of apoptotic cells reflects higher fluidity of the exposed membranes facilitating PS clustering.
Colonisation of stranded whale bones by lichens and mosses at Hennequin Point, King George Island, Antarctica

ABSTRACT This paper presents the details of lichens and mosses found on whale vertebrae substratum in the Admiralty Bay area, King George Island, Antarctica. Samples were taken in the coastal area at Hennequin Point, a relict of the Antarctic whaling era. The samples were collected from the upper surface of the whale bones found in the study area during the austral summer 2010–2011. A total of 15 lichen and two moss species were found. All species sampled are known in the Admiralty Bay area, both as pioneers and in more advanced succession stages in ice-free areas. These results suggest that the colonisation of whale bones is not new for Antarctic plants, but it is an additional substrate on which these plants can develop. A map showing the distribution of colonised bones and details of the usual substrata for the lichens and mosses found in this study are provided.
Phylogenetic Characterization of Atrazine-Degrading Bacteria Isolated from Agricultural Soil in Eastern Thailand

Abstract—In this study sugarcane field soils with a long history of atrazine application in Chachoengsao and Chonburi provinces have been explored for their potential of atrazine biodegradation. For the atrazine degrading bacteria isolation, the soils used in this study named ACS and ACB were inoculated in MS-medium containing atrazine. Six short rod and gram-negative bacterial isolates, which were able to use this herbicide as a sole source of nitrogen, were isolated and named as ACS1, ACB1, ACB3, ACB4, ACB5 and ACB6. From the 16S rDNA nucleotide sequence analysis, the isolated bacteria ACS1 and ACB4 were identified as Rhizobium sp. with 89.1-98.7% nucleotide identity, ACB1 and ACB5 were identified as Stenotrophomonas sp. with 91.0-92.8% nucleotide identity, whereas ACB3 and ACB6 were Klebsiella sp. with 97.497. 8% nucleotide identity.
Assessing the performance of near real-time rainfall products to represent spatiotemporal characteristics of extreme events: case study of a subtropical catchment in south-eastern Brazil

ABSTRACT This study evaluates the performance of four Near Real-Time (NRT) satellite rainfall products in estimating the spatiotemporal characteristics of different extreme rainfall events in a subtropical catchment in south-eastern Brazil. The Climate Prediction Centre Morphing algorithm (CMORPH), Tropical Rainfall Measuring Mission, Multisatellite Precipitation Analysis in real time (TMPA-RT), the Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks-Global Cloud Classification System (PERSIANN-GCCS), and the Hydro-Estimator are evaluated for monsoon seasons, based on their capability to represent four types of rainfall events distinguished for: (1) local and short duration, (2) long-lasting event, (3) short and spatial extent, and (4) spatial extent and long lasting. Since the events are defined relative to a percentile, the relative performance variation at different threshold levels (75th, 90th, and 95th) is also evaluated. The data from the 13 Automatic Weather Stations (AWSs) for the period from 2007 to 2014 are used as the reference. The results show that the product performance highly depends on the spatiotemporal characteristics of rainfall events. All four products tend to overestimate intense rainfall in the study area, especially in high altitude zones. CMORPH had the best overall performance to estimate different types of extreme spatiotemporal events. The results allow for developing a better understanding of the accuracy of the NRT products for the estimation of different types of rainfall events.
Biometrics in claim-based authentication framework

Nowadays biometric authentication and identification becomes a part of every-day life. As a result, many services emerge that rely on biometric-based access control. However, from a user point of view, supplying biometric information to many different service providers imposes high privacy and security risks. In this paper we focus on the use of biometrics in a claimed-based authentication framework. The frameworks allows for a limited number of identity providers, thus overcoming the need to supply biometric data to multiple untrustworthy service provides. We argue that in this case we can deploy the information-theoretic framework for privacy-preserving biometric systems for joint authentication and identification studied in Willems and Ignatenko [2010].
A Romantic Spirit in Priangan

A BSTRACT: Java, where the VOC (Verenigde Oost-Indische Compagnie or East Hindia-Dutch Company) — later a colonial state — established its base, was undoubtedly one of the most important regions in East Indies , which attracted colonial era of Europeans, not to mention those who relied on visual images, especially in 19 th century. It was the age when revolution broke out in Europe and liberal thoughts paved the way for private companies to open business in the colony, resulting various writings and drawings made by Europeans, especially the Dutch and British, on the East Indies, especially Java. This essay discusses three interrelated subjects in the history of European visual representation of Dutch East Indies (the present day Indonesia). First ly , the attractiveness of East Indies, especially Java, as Dutch colony in Asia, for 19 th century European society as could be seen from innumerable pictures and travelogues on the region and world-class exhibitions on the subject, in both the Netherlands and France, which displayed various aspects of the land and people. Second ly , the significance of Priangan, a mountainous region in western part of Java, in the eyes of 19 th century European , who traveled and conducted scientific investigations in the region so that the mountain region became a subject of various images and narratives. Third ly , the role of Franz Wilhelm Junghuhn (1809-1864), probably the most important researcher and explorer of Java at the time, in the production of visual images and travelogues of the land.

Dacite formation on Vesta: Partial melting of the eucritic crust

The Dominion Range 2010 howardite pairing group contains an evolved lithic clast of dacite composition. The dacite contains an assemblage of plagioclase, quartz, and augite, with minor pigeonite, troilite, ilmenite, FeNi metal, K‐feldspar, and phosphates. Primary augite occurs as >1 mm oikocrysts enclosing plagioclase. Quartz is abundant, comprising approximately 30% of the clast. Textural and geochemical characteristics support the hypothesis that the dacite is a primary igneous lithology, and represents a partial melt of the eucritic crust. Numerical modeling (MELTS) suggests 10–20% partial melting of a Juvinas source could have produced the dacite lithology; quantitative trace element modeling further supports crustal partial melting as the magma source for the dacite. The dacite likely formed as evolved‐melt pockets, and thus represents a volumetrically minor lithology in the Vestan crust, although its formation provides direct support for a genetic relationship between Stannern and residual trend eucrites, and is the first identification of residual eucrite complementary melts. We propose the dacite clast is the first characterized sample of tertiary crust on Vesta.
Manipulating Interface Standards as an Anti-Competitive Strategy

The creation of interface standards enables competition at the level of components, rather than competition in complete systems. Consumers often benefit from component competition. However, the standard-setting process might be manipulated to achieve anticompetitive ends. We consider the conditions under which a standards consortium could impose anticompetitive burdens on the market, and several strategies such a consortium might employ to achieve anti-competitive objectives. We present a new strategy - one-way standards - and discuss the conditions under which it can be anticompetitive.
