Atmospheric laser optics testbed (A_LOT): atmospheric propagation characterization, beam control, and imaging results (2003)

A new Army Research Laboratory (ARL) facility, the Atmospheric Laser Optics Testbed (A_LOT), designed to support research and development for a wide range of laser communication, atmospheric optics, beam control and imaging programs is presented. A_LOT provides a research laboratory environment that includes a 2.3 km near horizontal atmospheric optical path for studying the major challenges facing applications that employ laser beam propagation or imaging through the boundary layer atmosphere. Simultaneous and continual characterization of the meteorological and atmospheric turbulence parameters with characteristics of atmospheric imaging and laser beam propagation is accomplished with a network of various sensors connected to an automated data collection and archiving system. "Local weather" control capabilities allow generation of smoke, fog or rain. Devices and experiments can be controlled and data examined remotely via internet connection and remote client software. Examples of recent laser communication and imaging results obtained using the A_LOT facilities are presented.
Detection of Fingerprints Based on Elemental Composition Using Micro-X-Ray Fluorescence. (2005)

A method was developed to detect fingerprints using a technique known as micro-X-ray fluorescence. The traditional method of detecting fingerprints involves treating the sample with certain powders, liquids, or vapors to add color to the fingerprint so that it can be easily seen and photographed for forensic purposes. This is known as contrast enhancement, and a multitude of chemical processing methods have been developed in the past century to render fingerprints visible. However, fingerprints present on certain substances such as fibrous papers and textiles, wood, leather, plastic, adhesives, and human skin can sometimes be difficult to detect by contrast enhancement. Children's fingerprints are also difficult to detect due to the absence of sebum on their skin, and detection of prints left on certain colored backgrounds can sometimes be problematic. Micro-X-ray fluorescence (MXRF) was studied here as a method to detect fingerprints based on chemical elements present in fingerprint residue. For example, salts such as sodium chloride and potassium chloride excreted in sweat are sometimes present in detectable quantities in fingerprints. We demonstrated that MXRF can be used to detect this sodium, potassium, and chlorine from such salts. Furthermore, using MXRF, each of these elements (and many other elements if present) can be detected as a function of location on a surface, so we were able to 'see' a fingerprint because these salts are deposited mainly along the patterns present in a fingerprint (traditionally called friction ridges in forensic science). MXRF is not a panacea for detecting all fingerprints; some prints will not contain enough detectable material to be 'seen'; however, determining an effective means of coloring a fingerprint with traditional contrast enhancement methods can sometimes be an arduous process with limited success. Thus, MXRF offers a possible alternative for detecting fingerprints, and it does not require any additional chemical treatment steps which can be time consuming and permanently alter the sample. Additionally, MXRF is noninvasive, so a fingerprint analyzed by this method is left pristine for examination by other methods (eg. DNA extraction). To the best of the author's knowledge, no studies have been published to date concerning the detection of fingerprints by micro-X-ray fluorescence. Some studies have been published in which other spectroscopic methods were employed to examine the chemical composition of fingerprints (eg. IR, SEM/EDX, and Auger), but very few papers discuss the actual detection and imaging of a complete fingerprint by any spectroscopic method. Thus, this work is unique.

Electrostatically tuned dimensional crossover in LaAlO3/SrTiO3 heterostructures (2017)

We report a gate-tunable dimensional crossover in sub-micrometer-scale channels created at the LaAlO3/SrTiO3 interface. Conducting channels of widths 10 nm and 200 nm are created using conducting atomic force microscope lithography. Under sufficient negative back-gate tuning, the orbital magnetoconductance of the 200 nm channel is strongly quenched, and residual signatures of low-field weak-antilocalization become strikingly similar to that of the 10 nm channel. The dimensional crossover for the 200 nm channel takes place near the conductance quantum G = 2e2/h. The ability to tune the dimensionality of narrow LaAlO3/SrTiO3 channels has implications for interpreting transport in a variety of gate-tunable oxide-heterostructure devices.
Glomerular Pyrimidine Metabolism in Experimental Diabetic Nephropathy (1980)

Glomerular uracil nucleotide metabolism was studied in vivo in control and diabetic rats 48 h after the injection of streptozotocin. The animals were infused for 2 h with 3H-orotate and the fraction of infused dpm incorporated into glomerular uracil nucleotides and RNA/mg of glomerular DNA was calculated. Diabetic glomeruli showed an increase in RNA/DNA compared to controls (p less than 0.05) and a greater incorporation of 3H-orotate into uracil nucleotides and RNA. These changes were reversed by insulin therapy. In separate experiments the renal cortical uracil nucleotide pool was expanded by feeding chow supplemented with 0.5% orotate to rats for 6 months. Normal animals fed orotate developed significant glomerular basement membrane thickening (p less than 0.01) when compared to age-matched controls, which was morphologically indistinguishable from that of diabetics. Orotate feeding also produced further basement membrane thickening in diabetic rats. These results suggest that early diabetes is characterized by an increase in glomerular uracil nucleotides, and that chronic expansion of the uracil nucleotide pool is associated with glomerular basement membrane thickening.
Antibody Fc effector functions and IgG3 associate with decreased HIV-1 risk (2019)

HVTN 505 is a preventative vaccine efficacy trial testing DNA followed by recombinant adenovirus serotype 5 (rAd5) in circumcised, Ad5-seronegative men and transgendered persons who have sex with men in the United States. Identified immune correlates of lower HIV-1 risk and a virus sieve analysis revealed that, despite lacking overall efficacy, vaccine-elicited responses exerted pressure on infecting HIV-1 viruses. To interrogate the mechanism of the antibody correlate of HIV-1 risk, we examined antigen-specific antibody recruitment of Fcγ receptors (FcγRs), antibody-dependent cellular phagocytosis (ADCP), and the role of anti-envelope (anti-Env) IgG3. In a prespecified immune correlates analysis, antibody-dependent monocyte phagocytosis and antibody binding to FcγRIIa correlated with decreased HIV-1 risk. Follow-up analyses revealed that anti-Env IgG3 breadth correlated with reduced HIV-1 risk, anti-Env IgA negatively modified infection risk by Fc effector functions, and that vaccine recipients with a specific FcγRIIa single-nucleotide polymorphism locus had a stronger correlation with decreased HIV-1 risk when ADCP, Env-FcγRIIa, and IgG3 binding were high. Additionally, FcγRIIa engagement correlated with decreased viral load setpoint in vaccine recipients who acquired HIV-1. These data support a role for vaccine-elicited anti-HIV-1 Env IgG3, antibody engagement of FcRs, and phagocytosis as potential mechanisms for HIV-1 prevention.
Some applications of arithmetic groups in cryptography (2019)

Abstract In this paper, we will offer a new symmetric-key cryptographic scheme which is based on the existence of exponentially distorted subgroups in arithmetic groups. Aside from this, we will also provide new examples of distorted subgroups in {\mathrm{SL}_{n}(\mathbb{Z}[x])} which can be utilized for the same purpose.

Decreased cytotoxicity of 1-beta-D-arabinofuranosylcytosine in 9L rat brain tumor cells pretreated with alpha-difluoromethylornithine in vitro. (1983)

The effect of pretreating 9L rat brain tumor cells in vitro with 10 mM alpha-difluoromethylornithine (DFMO), an enzyme-activated, irreversible inhibitor of ornithine decarboxylase, on the cytotoxicity of 1-beta-D-arabinofuranosylcytosine (ara-C) was investigated using a colony-forming assay. DFMO-mediated polyamine depletion significantly decreased the cytotoxicity of ara-C. The addition of putrescine to DFMO-pretreated cells replenishes intracellular polyamine levels and prevents the decrease in ara-C cytotoxicity. Flow cytometric analysis showed that cells treated with ara-C alone entered S phase semisynchronously within 8 hr after the end of treatment. This phenomenon was virtually eliminated by DFMO pretreatment. Addition of putrescine to DFMO-pretreated cells before treatment with ara-C prevented this DFMO-induced cell cycle kinetic effect.
User-Centric Interference Nulling in Downlink Multi-Antenna Heterogeneous Networks (2016)

In heterogeneous networks (HetNets), strong interference due to spectrum reuse affects each user's signal-to-interference ratio (SIR), and hence is one limiting factor of network performance. In this paper, we propose a user-centric interference nulling (IN) scheme in a downlink large-scale HetNet to improve coverage/outage probability by improving each user's SIR. This IN scheme utilizes at most maximum IN degree of freedom (DoF) at each macro-BS to avoid interference to uniformly selected macro (pico) users with signal-to-individual-interference ratio (SIIR) below a macro (pico) IN threshold, where the maximum IN DoF and the two IN thresholds are three design parameters. Using tools from stochastic geometry, we first obtain a tractable expression of the coverage (equivalently outage) probability. Then, we analyze the asymptotic coverage/outage probability in the low and high SIR threshold regimes. The analytical results indicate that the maximum IN DoF can affect the order gain of the outage probability in the low SIR threshold regime, but cannot affect the order gain of the coverage probability in the high SIR threshold regime. Moreover, we characterize the optimal maximum IN DoF which optimizes the asymptotic coverage/outage probability. The optimization results reveal that the IN scheme can linearly improve the outage probability in the low SIR threshold regime, but cannot improve the coverage probability in the high SIR threshold regime. Finally, numerical results show that the proposed scheme can achieve good gains in coverage/outage probability over a maximum ratio beamforming scheme and a user-centric almost blank subframes (ABS) scheme.
Effect of neurotensin on intestinal capillary permeability and blood flow (1984)

Experiments were performed in 10 cats of either sex to ascertain the effects of postprandial arterial plasma concentrations of neurotensin (NT) on intestinal capillary permeability and blood flow. NT was infused intra-arterially into an isolated perfused loop of terminal ileum to produce a 182 +/- 15 (SE) pM plasma NT concentration. Intestinal lymph (L) and plasma (P) protein concentrations were measured at various venous pressures under control conditions and during NT infusion. The osmotic reflection coefficient (sigma d) was estimated under all conditions assuming sigma d = 1 - L/P at high capillary filtration rates. NT infusion significantly (P less than 0.001) reduced sigma d to 0.73 +/- 0.02 (SE) from a control level of 0.91 +/- 0.01. NT infusion also significantly increased intestinal blood flow [47.0 +/- 4.3 (SE) ml X min-1 X 100 g-1] versus control (36.6 +/- 3.2 ml X min-1 X 100 g-1), a 28.4% increase. Intestinal vascular resistance was decreased from 3.21 +/- 0.31 to 2.42 +/- 0.28 mmHg X min X ml-1 X 100 g in the absence of a change in local mean arterial blood pressure. Pore-stripping analysis of lymph and plasma solute fractions during NT infusion at high lymph flows predicted two populations of pores, 330-A and 46-A radius, accounting for 31 and 67%, respectively, of the total transcapillary hydraulic flow. NT infusion preferentially increased large-pore radius as a means of increasing intestinal capillary permeability. The rates of small- to large-pore areas and numbers were 106:1 and 5,225:1, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
Loss of Control Car Accidents on Indian Roads - Benefit Estimation of ESC (2019)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;India has one of the highest growth rates of individual mobility in the world, as well as one of the largest numbers of road casualties. Modern active safety systems are slowly becoming established in the Indian passenger car market. The intension of this study is to investigate the effectiveness of the car safety feature Electronic Stability Control (ESC) for India. The Indian accidents has to be analysed to identify the reliable root cause. For this purpose, passenger car Loss of Control accidents were investigated in more detail with the aim of estimating the safety potential of ESC for India. A methodology is developed to extrapolate the in-depth accident database of Road Accident Sampling System for India (RASSI) to the entire accident situation in India. Loss of Control accidents are analysed with regard to their root causes, crash consequences and contributing factors. The initial findings of the study reveals that the accident scenario Loss of Control of cars is significantly prominent in India. The analysis shows that about 40,000 Loss of Control car accidents with injury occur in India every year and in addition, about 4,000 accidents due to sudden tire damage. Another important impact of the use of RASSI is that the phenomenon of underreporting becomes visible. This issue is also included in this study for the first time. It is found that up to 33,000 car accidents with casualties could be positively influenced if ESC would be equipped in all passenger cars. This corresponds to 12% of all car accidents with casualties in India and ESC could prevent up to 9,000 road deaths and around 14,000 serious injured road users annually. However, the study furthermore shows that infrastructure measures and safety awareness can also contribute to reduce the number of car accidents and or casualties.&lt;/div&gt;&lt;/div&gt;

Primary receiver localization using sparsity and interference tweets (2013)

A hierarchical access setup is considered, where secondary users can (re-)use frequency bands allocated to licensed systems, provided ongoing primary communications are not overly disrupted. Since conventional spectrum sensing schemes can detect and localize “active” sources but not “passive” users, the number of primary receivers and their locations are generally unknown. Supposing a minimal coordination between primary and secondary systems, a novel method for unveiling areas where primary receivers are located is proposed in this paper. The primary system broadcasts short messages - here refereed to as “interference tweets” - indicating the number of receivers that are interfered. Using these tweets, together with a grid-based discretization of the primary coverage region, the locations where receivers are likely to reside are obtained by solving a sparse linear regression problem. Subsequently, the estimated locations are used to optimize resource allocation of the secondary network operation under interference constraints.
Real-Time Visibility-Based Fusion of Depth Maps (2007)

We present a viewpoint-based approach for the quick fusion of multiple stereo depth maps. Our method selects depth estimates for each pixel that minimize violations of visibility constraints and thus remove errors and inconsistencies from the depth maps to produce a consistent surface. We advocate a two-stage process in which the first stage generates potentially noisy, overlapping depth maps from a set of calibrated images and the second stage fuses these depth maps to obtain an integrated surface with higher accuracy, suppressed noise, and reduced redundancy. We show that by dividing the processing into two stages we are able to achieve a very high throughput because we are able to use a computationally cheap stereo algorithm and because this architecture is amenable to hardware-accelerated (GPU) implementations. A rigorous formulation based on the notion of stability of a depth estimate is presented first. It aims to determine the validity of a depth estimate by rendering multiple depth maps into the reference view as well as rendering the reference depth map into the other views in order to detect occlusions and free- space violations. We also present an approximate alternative formulation that selects and validates only one hypothesis based on confidence. Both formulations enable us to perform video-based reconstruction at up to 25 frames per second. We show results on the multi-view stereo evaluation benchmark datasets and several outdoors video sequences. Extensive quantitative analysis is performed using an accurately surveyed model of a real building as ground truth.

The Evolution of Human Fungal Pathogens (2014)

This chapter focuses primarily on the subset of human pathogenic fungi. Even among this relatively small subset of organisms, there is extensive variation in phylogenetic ancestry, pathogenic strategies, ecology, prevalence, and outcome of infection. The major fungal pathogens constitute a diverse group of organisms. With the exception of Candida spp. and Malassezia furfur, all other pathogenic fungi discussed in this chapter are saprophytic. Pathogens can be classified as generalists or specialists depending on their host range. The chapter also focuses on broad areas of the macroevolution of fungal pathogenesis. In fungi, the two important genetic changes that result in microevolution are genetic rearrangements and point mutations. Macroevolution in terms of speciation has led to the development of multiple pathogenic fungal species. The chapter proposes different hypotheses and supporting data on the evolution and development of fungal pathogenesis. Though the specific mechanisms of evolution and development of virulence factors have not been elucidated, there are clear data implicating soil amoebae as a natural predator that may maintain virulence in the fungal habitat. Given increasing interest in this area, future studies will shed additional light on the evolution of fungal pathogenesis.

Improving DAS acquisition by real-time monitoring of wireline cable coupling (2016)

One of the key challenges in using the Distributed Acoustic Sensing (DAS) method for seismic survey in exploration wells is to achieve sufficient coupling between the wireline cable and the vertical borehole to ensure the data quality. Many numerical simulations have been conducted to understand the behavior of the cable when it is lowered in a well. However, this simulation method requires too much time and processing power to be effective during Vertical Seismic Profile (VSP) survey and is not an interactive check on the state of the cable. This paper presents a new method to monitor the strain distribution along the cable and to estimate the depth distribution of the cable using a Brillouin backscattering interpretation technique in real time. Consequently, the field engineer has the ability to perform a real time quality check to determine the right amount of slack to improve the DAS data quality.
