Efficient and Effective Spam Filtering and Re-ranking for Large Web\n Datasets (2010)

The TREC 2009 web ad hoc and relevance feedback tasks used a new document\ncollection, the ClueWeb09 dataset, which was crawled from the general Web in\nearly 2009. This dataset contains 1 billion web pages, a substantial fraction\nof which are spam --- pages designed to deceive search engines so as to deliver\nan unwanted payload. We examine the effect of spam on the results of the TREC\n2009 web ad hoc and relevance feedback tasks, which used the ClueWeb09 dataset.\nWe show that a simple content-based classifier with minimal training is\nefficient enough to rank the "spamminess" of every page in the dataset using a\nstandard personal computer in 48 hours, and effective enough to yield\nsignificant and substantive improvements in the fixed-cutoff precision (estP10)\nas well as rank measures (estR-Precision, StatMAP, MAP) of nearly all submitted\nruns. Moreover, using a set of "honeypot" queries the labeling of training data\nmay be reduced to an entirely automatic process. The results of classical\ninformation retrieval methods are particularly enhanced by filtering --- from\namong the worst to among the best.\n
Propagation of Fatigue Cracks Emanating from Sharp Notches under Different Loading Direction (2007)

The present paper is aimed at investigating the behaviour of fatigue cracks emanating from sharp V-shaped notches. To this purpose, several tests has been conducted on Al-7075-T651 notched specimens using a servohydraulic machine by changing the directions and levels of the applied load. The crack growth have been interpreted on the basis of a linear elastic fracture mechanics approach by adopting a weight function derived by the authors for the calculation of the stress intensity factors (SIFs) of inclined edge-cracks emanating from V-shaped notches.
CXCL17 Chemokine–Dependent Mobilization of CXCR8+CD8+ Effector Memory and Tissue-Resident Memory T Cells in the Vaginal Mucosa Is Associated with Protection against Genital Herpes (2018)

Circulating conventional memory CD8<sup>+</sup> T cells (i.e., the CD8<sup>+</sup> effector memory T [T<sub>EM</sub>] cell and CD8<sup>+</sup> central memory T [T<sub>CM</sub>] cell subsets) and the noncirculating CD8<sup>+</sup> tissue-resident memory T (T<sub>RM</sub>) cell subset play a critical role in mucosal immunity. Mucosal chemokines, including the recently discovered CXCL17, are also important in mucosal immunity because they are homeostatically expressed in mucosal tissues. However, whether the CXCL17 chemokine contributes to the mobilization of memory CD8<sup>+</sup> T cell subsets to access infected mucosal tissues remains to be elucidated. In this study, we report that after intravaginal HSV type 1 infection of B6 mice, we detected high expression levels of CXCL17 and increased numbers of CD44<sup>high</sup>CD62L<sup>low</sup>CD8<sup>+</sup> T<sub>EM</sub> and CD103<sup>high</sup>CD8<sup>+</sup> T<sub>RM</sub> cells expressing CXCR8, the cognate receptor of CXCL17, in the vaginal mucosa (VM) of mice with reduced genital herpes infection and disease. In contrast to wild-type B6 mice, the CXCL17<sup>-/-</sup> mice developed 1) fewer CXCR8<sup>+</sup>CD8<sup>+</sup> T<sub>EM</sub> and T<sub>RM</sub> cells associated with more virus replication in the VM and more latency established in dorsal root ganglia, and 2) reduced numbers and frequencies of functional CD8<sup>+</sup> T cells in the VM. These findings suggest that the CXCL17/CXCR8 chemokine pathway plays a crucial role in mucosal vaginal immunity by promoting the mobilization of functional protective CD8<sup>+</sup> T<sub>EM</sub> and CD8<sup>+</sup> T<sub>RM</sub> cells, within this site of acute and recurrent herpes infection.
Pseudomorphic Growth of a Single Element Quasiperiodic Ultrathin Film on a Quasicrystal Substrate (2004)

An ultrathin film with a periodic interlayer spacing was grown by the deposition of Cu atoms on the fivefold surface of the icosahedral Al70Pd21Mn9 quasicrystal. For coverages from 5 to 25 monolayers, a distinctive quasiperiodic low-energy electron diffraction pattern is observed. Scanning tunneling microscopy images show that the in-plane structure comprises rows having separations of S=4.5+/-0.2 A and L=7.3+/-0.3 A, whose ratio equals tau=1.618... within experimental error. The sequences of such row separations form segments of terms of the Fibonacci sequence, indicative of the formation of a pseudomorphic Cu film.
Reduced complexity MIMO detectors for LDPC coded systems (2005)

We consider the performance and complexity analysis of low-density parity-check (LDPC) coded multiple-input multiple-output (MIMO) systems with reduced complexity detectors in fast Rayleigh fading channels. We use a turbo iterative detection-and-decoding receiver which combines a soft MIMO demodulator and a message-passing LDPC decoder We examine three low complexity detectors: minimum mean-square error (MMSE) with soft interference cancellation (SIC), MMSE suppression, and MMSE with hard decision interference cancellation (MMSE-HIC). We compare the performance and complexity of these detectors with the standard soft maximum a posteriori (MAP) detector and show that they provide a lower computational complexity with only a small penalty in performance (/spl sim/0.5 dB). We also provide comparisons with the Shannon capacity limits for ergodic multiple-antenna channels and show that an LDPC coded system using a length 15,000 code and QPSK modulation with reduced-complexity detection operates 2 and 3 dB from the ergodic capacity of the Rayleigh MIMO channel.
Traceroute-Based Fast Peer Selection without Offline Database (2006)

The extreme heterogeneity in the P2P Internet environment causes the connections to candidate peers to vary significantly. Thus, selecting good candidate peers is critical to P2P networking performance. While most research in the literature focus on selecting peers with low latency, high uploading bandwidth, and high serving stability by time-consuming end-to-end measurement, we address how to quickly narrow the scope of good candidate peers. In this paper, we proposed to pick out the close peers from the same location or with low round-trip time from each other, by observing that close peers share routers along the traceroute path to the same destination. Our method only maintains online peers's traceroute records, without any offline database. Experiments with real traceroute records from 352 different IP addresses around the world verify the efficiency of our method

Ipratropium bromide spray as treatment for sialorrhea in Parkinson's disease (2007)

Sialorrhea is a significant problem in advanced Parkinson's disease (PD). Current treatment options include systemic anticholinergics which frequently cause side effects. We hypothesized that sublingual application of ipratropium bromide spray, an anticholinergic agent that does not cross the blood brain barrier, may reduce drooling without systemic side effects. We performed a randomized, double blind, placebo-controlled, crossover study in 17 subjects with PD and bothersome drooling. Patients were randomized to receive ipratropium bromide or placebo (one to two sprays, maximum of four times per day) for 2 weeks followed by a 1 week washout and crossover for further 2 weeks of treatment. The primary outcome was an objective measure of weight of saliva production. Secondary outcomes were subjective rating of severity and frequency of sialorrhoea using home diaries, United Parkinson's Disease Rating Scale (UPDRS) part II salivation subscore, parkinsonian disability using UPDRS, and adverse events. Ipratropium bromide spray had no significant effect on weight of saliva produced. There was a mild effect of treatment on subjective measures of sialorrhea. There were no significant adverse events. Ipratropium bromide spray was well tolerated in subjects with PD. Although it did not affect objective measures of saliva production, further studies in parkinsonism may be warranted.
UWB front-end for SAR-based imaging system (2010)

A planarly fed UWB leaky lens antenna is presented integrated with wide band transmit and receive front-end electronics, to be used in a SAR-based imaging system. The unique non-dispersive characteristics of this antenna over a very wide bandwidth, together with the dual band front-end electronics based on 'off the shelf' components and integrated using standard PCB technology makes them very attractive as transmit-receive element for a MIMO array configuration. Design and measurement results of the leaky lens antenna characteristics are presented, and design considerations for the integrated mm-Wave electronics are discussed.
Melanocortin‐1 receptor‐targeting with radiolabeled cyclic α‐melanocyte‐stimulating hormone analogs for melanoma imaging (2010)

Melanoma is a type of skin cancer known for its high aggressiveness, early dissemination of metastases, and poor prognosis once metastasized. Thus, early diagnosis of melanoma is a key issue for increasing patient survival. The overexpression of melanocortin-1 receptors (MC1R) in isolated melanoma cells and melanoma tissues led to the radiolabeling of several linear and cyclic MC analogs for melanoma imaging or therapy. Cyclization of α-melanocyte stimulating hormone (α-MSH) peptides has been successfully used to improve binding affinity and in vivo stability of peptides. Herein, we describe the different peptide cyclization strategies recently reported for radiolabeled α-MSH analogs and discuss how such strategies affect MC1R binding affinity, pharmacokinetic profile, and MC1R-melanoma imaging. This review also highlights how the nature of the radiometal and labeling approach influence those properties. Among the cyclized α-MSH peptides reported, (99m)Tc/(111)In-labeled metal-cyclized and lactam bridge-cyclized peptides displayed the highest melanoma and lowest renal uptake values in B16/F1 melanoma-bearing mice and became the most promising tools to be further explored as potential melanoma imaging probes.
Age-related changes of corneal endothelium in normal eyes with a non-contact specular microscope (2010)

METHODS: Three consecutive examinations were carried out using a non-contact specular microsopy in 256 right eyes of 256 healthy patients (88 males, 168 females) with ages from 6 to 82 years (mean ± SD, 44 ± 22 years) using a semi-automated mode of image analysis. Central corneal thickness (CCT), standard error of cell surface area (SEM), endothelial cell density (ECD), average cell size (ACS), coefficient of variation in cell size (CV), hexagonality index (HI) as well as the classification of cells by surface area and geometric shape were obtained. Correlations between quantitative descriptors and their associated standard deviation with subject’s age were investigated. RESULTS: All quantitative parameters of the corneal endothelial mosaic displayed differences among different age groups. ECD decreased and ACS increased at an average rate of 5 to 6%/decade (-144 cells/mm 2 and +23µm 2 , respectively). Significant age-related changes were also found for cell surface counts, while weaker or non-significant correlations were observed for counts by cell geometry. Overall all parameters displayed a high level of repeatability with no significant differences among three consecutive readings or between individual readings and the mean value. CONCLUSIONS: Endothelial changes consisted on decrease in ECD and increase in ACS. Conversely, changes in CV and HI did not seem to be clinically significant suggesting that normal endothelial cell loss is an organized process that does not imply a disorganization of the endothelial mosaic in geometric terms.

The effects of hypoxemia with progressive acidemia on fetal renal function in sheep. (1989)

In order to determine the effects of fetal hypoxemia on renal blood flow, glomerular filtration rate (GFR) and urethral and urachal urine output, we examined the effects of 3 h maternally-induced (9% O2, 3% CO2, 88% N2) fetal hypoxaemia on 10 chronically-instrumented fetal sheep between 127-135 days of gestation. Fetal arterial pH fell significantly during the second and third hours of hypoxia and this coincided with a significant increase in fetal arterial blood pressure (P less than 0.05). During the second hour of hypoxia, with mild acidaemia, fetal GFR decreased significantly and then, during the third hour, fetal GFR, urethral and total urine output were significantly elevated. During the 2-h recovery period urachal and total, but not urethral urine output, were significantly elevated (P less than 0.05). The data suggested that the increase in GFR and urine output measured during the third hour of hypoxia and the recovery period may reflect a pressure diuresis.
Statistical Energy Analysis of Vibration Transmission into an Instrument Package (1967)

&lt;div class="htmlview paragraph"&gt;Random vibration transmission from a vibrating source into an instrument package is analyzed using statistical energy analysis techniques. A general outline of these techniques, followed by a specific application to an instrument box attached to a vibrating plate, is presented. Consideration is also given to vibration isolation of the instrument box and to a novel method of performing vibration tests of small instrument packages and components. The experimental results presented agree well with theoretical results and indicate that these new analysis techniques offer new insight into practical high-frequency vibration problems.&lt;/div&gt;
Liquid flow along a solid surface reversibly alters interfacial chemistry (2014)

In nature, aqueous solutions often move collectively along solid surfaces (for example, raindrops falling on the ground and rivers flowing through riverbeds). However, the influence of such motion on water-surface interfacial chemistry is unclear. In this work, we combine surface-specific sum frequency generation spectroscopy and microfluidics to show that at immersed calcium fluoride and fused silica surfaces, flow leads to a reversible modification of the surface charge and subsequent realignment of the interfacial water molecules. Obtaining equivalent effects under static conditions requires a substantial change in bulk solution pH (up to 2 pH units), demonstrating the coupling between flow and chemistry. These marked flow-induced variations in interfacial chemistry should substantially affect our understanding and modeling of chemical processes at immersed surfaces.
Laser-Assisted 3D Printing of Functional Graded Structures from Polymer Covered Nanocomposites: A Self-Review (2016)

As a method for conservation of nanoparticles with perspective properties, the three-dimensional (3D) printing is a promising technique for modeling, fabricating of functional graded structures (FGS) with nanoadditives and functional devices. The stabilization of nanoparticles in a polymeric matrix and additionally reinforced porous structure makes it possible to arrange a desired distribution of the nanoparticles in the polymer and thus to protect them from oxidation and corrosion and even to design not only the FGS but also micro/nanoelectromechanical systems (M/NEMS) devices. The synthesized nanocomposites with controlled porosity and large-specific surface may also find their application in implantation, catalysis, lab-on-chips, drug delivery systems, and 3D crystalline structures for hydrogen storage devices.
Downhole Diagnosis of Drilling Dynamics Data Provides New Level Drilling Process Control to Driller (1998)

Abstract Vibrations are inevitable in drilling. However, the severity of vibrations and their detrimental influence on the drilling process depends on bit and Bottom Hole Assembly (BHA) design, the formation being drilled and, most importantly, the choice of drilling parameter such as WOB and RPM. When adjusting the drilling parameters the driller very often relies solely on his experience which (in the best case) is gained on offset wells. A new Measurement-While-Drilling (MWD) based service significantly improves this situation by providing real-time feedback about the drilling process to the driller. A downhole tool containing various dynamics sensors, and a high speed data acquisition and processing system, continuously monitors BHA vibrations and diagnoses the occurrence of vibration related problems such as stick-slip, whirl, bit bounce etc. The type and severity of the diagnosed vibration are transmitted to the surface and displayed on a rig floor monitor. This allows the driller to take immediate remedial action by changing drilling parameters and, more importantly, optimize the entire drilling process. This paper presents both the downhole tool and the surface display as well as the overall service concept. The downhole processing algorithms are also outlined. Several results from first downhole runs show how dynamic dysfunctions are identified and assessed downhole. P. 649
UTILIZATION OF LOW NOx COAL COMBUSTION BY-PRODUCTS (1998)

Potomac Electric Power Company (PEPCo) Class F fly ash is the first material to be worked on in this project. A head sample was taken and a screen analysis performed. Each size fraction was evaluated for LOI content. Table 1 shows the distribution of the as-received material by size and LOI content. From the data, 80% of the as-received material is finer than 400 mesh and the LOI content goes from high at coarse fractions and decreases to a low at the finest size fraction. SEM chemical analysis identified the as-received fly ash to mainly consist of silica (46%), aluminum oxide (21%), and iron in various forms (16%). The high iron content presents an extreme case as compared to other fly ash samples we have evaluated previously. Its effect on product testing applications could identify physical and chemical limitations as product testing progresses. Because of the high iron content, it was realized that magnetic separation would be incorporated into the early part of the pilot plant flowsheet to remove magnetic iron and, hopefully, reduce the total iron content. More analytical data will be presented in the next reporting period.

Biomimetic Templated Self-Assembly of Light Harvesting Nanostructures. Final report (2018)

In this project we were interested in studying the self-assembly of supramolecular antenna-like structures with very specific features using block copolymers as templates. This system mimics naturally-occurring ultra-efficient light harvesting antennas found in Green Sulfur Bacteria, so-called Chlorosomes. The complex organization of these antennas, which are composed of small organic chromophores (BacterioChlorophyl C in this case) is dictated by the shape of the mesostructure as well as the internal interactions between the chromophores themselves and the polymer-chromophore interactions. With this in mind, the overall aim of this project is to find which are the design rules for creating tailored antenna–like assemblies. A desired outcome would be to use single molecules that have already been shown to be functional and incorporate them to block copolymers to obtain the desired enhanced functionality. We have come a long way into understanding how to achieve this as shown in this report, both theoretically and experimentally. Along the way, we were also interested in developing new computational techniques for studying such self-assembly processes and insights from this system that may be of help in other fields. Such has been the case and we have discovered new phases of self-assembling matter, their limits and those of active matter as well.
Simulation of Heavy-Duty Vehicles in Platooning Scenarios (2018)

Connectivity and automation provide the potential to use information about the environment and future driving to minimize energy consumption. In order to achieve this goal, the designers of control strategies need to simulate a wide range of driving situations that can interact with other vehicles and the infrastructure to account for the specific powertrain characteristics of each automated vehicle. We present here a simulation framework called RoadRunner, which aims to facilitate the design of powertrain-aware eco-driving algorithms and a better understanding of the interactions between automation and powertrain technology. RoadRunner allows users to simulate both powertrain and longitudinal dynamics within a simulated environment. The user defines the scenario to be simulated by providing a route profile, intersection control types, number of vehicles, vehicle class, powertrain technology, connectivity, and automation level. RoadRunner then builds a Simulink diagram of the scenario, including the information flows between vehicles, and between vehicles and the road. After the simulation, the user can analyze the driving, component operations, and detailed energy consumption rates for each simulated vehicle. We present a case study on heavy-duty vehicles platooning. Using RoadRunner and detailed road data from digital maps, we quantify the impact of gap setting on fuel consumption, for a real-world route.
