A Study of Consumers’ Perceived Risk, Privacy Concern, Information Protection Policy, and Service Satisfaction in the Context of Parcel Delivery Services (2017)

The proposed conceptual framework is based in the relationships among knowledge of personal information security, trust on the personal information security policies of parcel delivery service companies, privacy concern, trust in and risk of parcel delivery services, and user satisfaction with parcel delivery services. Drawing upon both cognitive theory of emotion and cognitive emotion theory that complement each other, we propose a research model and examine the relationships between cognitive and emotional factors and the usage of parcel delivery services. The proposed model is validated using data from customers who have previously used parcel delivery services. The results show a significant relationship between the cognitive and affective factors and the usage of parcel delivery services. This study enhances our understanding of parcel delivery services based on the consumers’ psychological processes and presents useful implications on the importance of privacy and security in these services.
DNA Damage in Mammalian Cells by Non‐thermal Atmospheric Pressure Microsecond Pulsed Dielectric Barrier Discharge Plasma is not Mediated by Ozone (2012)

Abstract Non‐thermal dielectric barrier discharge (DBD) plasma is now being widely developed for various clinical applications 1,2 but the mechanisms of interaction of such plasmas with mammalian cells are still not well understood. It is known that DBD plasma produces ozone and it is possible that the effects of plasma may be mediated purely by ozone. Although typically requiring much higher treatment time than the typical plasma treatment times reported here, ozonation is, in fact, widely employed to kill microorganisms in water and is also used for wound healing. It has been shown earlier that plasma treatment of mammalian cells submerged in a shallow layer of culture medium can result in dose dependent DNA damage. We wanted to understand the role of ozone in mediating the interaction of non‐thermal plasma DBD plasma with mammalian cells. Upon comparing plasma treatment of mammalian breast epithelial cells with ozone treatment we found that ozone treatment is qualitatively different from non‐thermal DBD plasma and in fact does not play a role in mediating the observed effects of plasma on mammalian cells. magnified image

Treatment-Naïve Ulcerative Colitis Patient Treated With Lyophilized Full Spectrum Microbiota: A Case Study (2017)

Introduction: Ulcerative Colitis (UC) is a chronic relapsing-remitting inflammatory disease of the large intestine. It is thought that UC is a result of an aberrant reaction of the mucosa to the normal gut microbiome in genetically predisposed individuals. The use of trans-colonoscopic/enema fecal microbiota transplantation (FMT) in UC has succeeded in attaining clinical remission. Orally administered encapsulated lyophilized FMT product has distinct advantages over colonoscopically or enema-infused therapy. We report here for the first time the use of lyophilized full-spectrum microbiota (LFSM) in treating a patient with pancolitis. Case Report: A 44 y/o treatment-naive male presented with 1 y history of diarrhea, blood, mucus, cramping and abdominal pain. The patient experienced severe pain upon defecation, incontinence whilst driving, loss of appetite and weight loss of 16lbs. Collection of donor stool for LFSM production was carried out as per AGA Consensus Guidelines. Stool was homogenized with cryoprotectant and the resulting slurry was lyophilized and encapsulated in DR gel capsules containing ˜1.6 x 1011 viable cells/capsule. The patient was treated with a total of 426 capsules over a 13-week induction period. During this period, symptom questionnaires were collected and stools cultured for pathogens to assess efficacy and safety of the LFSM treatment. Discussion of Findings: The patients' UC symptoms showed marked improvement. By week 6 post-treatment, blood and mucus were barely visible in stool, by week 14 it was nil. His incontinence ceased and bowel motions decreased to 2-3/day - type 4 on the Bristol Stool Chart (BSC). With continuing treatment, the calprotectin levels reduced from 600μg/g in week 22 to 344μg/g in week 26. This confirmed the ongoing inflammation reduction seen by endoscopic review in Figure 1. The patient did not report any side-effects relating to the tolerability of the treatment. This case represents that UC can be successfully treated with oral LFSM. The Quality of Life (QoL) improvement seen by the patient is remarkable in that besides UC symptom improvement; there was a significant increase in energy levels that resulted in daily exercise and confidence to recommence work due to reduced incontinence. This patient is continuing well on maintenance treatment. LFSM treatment was efficacious and safe when treating a treatment-naïve UC patient with pancolitis, resulting in an overall improved QoL.Figure: Pre and post treatment symptom severity for UC patient treated with LFSM.Figure: Left: Sigmoid Colon showing marked UC inflammation pre-treatment (week -1). Right: Sigmoid Colon showing marked reduction in inflammation with stool attached to a minimally inflamed wall (week 20).
Measuring the In-Process Figure, Final Prescription, and System Alignment of Large Optics and Segmented Mirrors Using Lidar Metrology (2011)

The fabrication of large optics is traditionally a slow process, and fabrication capability is often limited by measurement capability. W hile techniques exist to measure mirror figure with nanometer precis ion, measurements of large-mirror prescription are typically limited to submillimeter accuracy. Using a lidar instrument enables one to measure the optical surface rough figure and prescription in virtuall y all phases of fabrication without moving the mirror from its polis hing setup. This technology improves the uncertainty of mirror presc ription measurement to the micron-regime.
Extracellular Vimentin/VWF (von Willebrand Factor) Interaction Contributes to VWF String Formation and Stroke Pathology (2018)

Background and Purpose- VWF (von Willebrand factor) strings mediate spontaneous platelet adhesion in the vascular lumen, which may lead to microthrombi formation and contribute to stroke pathology. However, the mechanism of VWF string attachment at the endothelial surface is unknown. We tested the novel hypothesis that VWF strings are tethered to the endothelial surface through an interaction between extracellular vimentin and the A2 domain of VWF. We further explored the translational value of blocking this interaction in a model of ischemic stroke. Methods- Human endothelial cells and pressurized cerebral arteries were stimulated with histamine to elicit VWF string formation. Recombinant proteins and antibodies were used to block VWF string formation. Mice underwent transient middle cerebral artery occlusion with reperfusion. Just before recanalization, mice were given either vehicle or A2 protein (recombinant VWF A2 domain) to disrupt the vimentin/VWF interaction. Laser speckle contrast imaging was used to monitor cortical perfusion. Results- Pressurized cerebral arteries produced VWF strings following histamine stimulation, which were reduced in arteries from Vim KO (vimentin knockout) mice. VWF string formation was significantly reduced in endothelial cells incubated with A2 protein or antivimentin antibodies. Lastly, A2 protein treatment significantly improved cortical reperfusion after middle cerebral artery occlusion. Conclusions- We provide the first direct evidence of cerebral VWF strings and demonstrate that extracellular vimentin significantly contributes to VWF string formation via A2 domain binding. Lastly, we show that pharmacologically targeting the vimentin/VWF interaction through the A2 domain can promote improved reperfusion after ischemic stroke. Together, these studies demonstrate the critical role of VWF strings in stroke pathology and offer new therapeutic targets for treatment of ischemic stroke.
Albuminuria Is Associated with Endothelial Dysfunction and Elevated Plasma Endothelin-1 in Sickle Cell Anemia (2016)

This study provides more definitive evidence for the association of albuminuria with endothelial dysfunction in SCD. Elevated circulating levels of ET-1 may contribute to SCD-related glomerulopathy by mediating endothelial dysfunction.
Ü-BOEFT#JPTDJFODF %POPUEJTUSJCVUF (2011)

Infection by the human protozoan parasite Leishmania can lead, depending primarily on the parasite species, to either cutaneous or mucocutaneous lesions, or fatal generalized visceral infection. In the New World, Leishmania (Viannia) species can cause mucocutaneous leishmaniasis (MCL). Clinical MCL involves a strong hyper-inflammatory response and parasitic dissemination (metastasis) from a primary lesion to distant sites, leading to destructive metastatic secondary lesions especially in the nasopharyngal areas. Recently, we reported that metastasizing, but not non-metastatic strains of Leishmania (Viannia) guyanensis, have high burden of a non-segmented dsRNA virus, Leishmania RNA Virus (LRV). Viral dsRNA is sensed by the host Toll-like Receptor 3 (TLR3) thereby inducing a pro-inflammatory response and exacerbating the disease. The presence of LRV in Leishmania opens new perspectives not only in basic understanding of the intimate relation between the parasite and LRV, but also in understanding the importance of the inflammatory response in MCL patients. Leishmania are human protozoan parasites endemic in 88 countries, with a disease prevalence of 12 million cases accompanied by 80,000 annual fatalities. These infections induce a large spectrum of clinical pathologies, mainly cutaneous (CL), mucosal (MCL) and visceral leishmaniasis (VL). The differences arise primarily from infection by different Leishmania species, such as L. major, L. braziliensis and L. infantum respectively.
Nisin-Producing Lactococcus lactis Strains Isolated from Human Milk (2004)

Characterization by partial 16S rRNA gene sequencing, ribotyping, and green fluorescent protein-based nisin bioassay revealed that 6 of 20 human milk samples contained nisin-producing Lactococcus lactis bacteria. This suggests that the history of humans consuming nisin is older than the tradition of consuming fermented milk products.
Electrohydrodynamic Enforcement of Evaporation and Gas Flow (2011)

The net drag result of the ionic current in a conductive fluid, such as electrohydrodynamic (EHD) effect and electrospray (Taylor cone effect), has been investigated as a space and energy saving technology for enforced heat and mass management. Electrostatically enforced evaporation, convection, and phase-change thermal transfer are briefly discussed and experimentally evaluated. The emphasis of the investigation was on the maximal efficiency of the consumed power. The significance of EHD phenomena for energy saving is demonstrated with examples of temperature stabilization for solid-state lighting and the dewatering of pulp in the paper industry.
Construction and Characterization of Several New Lanthanide−Organic Frameworks: From 2D Lattice to 2D Double-Layer and to Porous 3D Net with Interweaving Triple-Stranded Helixes (2008)

Five novel lanthanide−organic frameworks: [Ln(NTA)(H2O)2]·H2O (Ln = Eu (1)) and [Ln(NTA)(H2O)] (Ln = Tb (2), Ho (3, 4), and Tm (5); NTA = nitrilotriacetate anion) have been constructed by a rational synthetic strategy. 1 and 5 were successfully obtained by tuning the number of coordinated water molecules to lanthanide ions under different temperatures, while 2 and 3 were prepared under the same synthetic temperature as that of 5. Structural analyses indicate that they belong to three different space groups. 1 displays an irregular two-dimensional (2D) lattice consisting of alternative L- and R-type single-chain helixes, and both 2 and 3 are 2D double layer structures, while 4 and 5 are porous three-dimensional (3D) frameworks. Surprisingly, although 3 and 4 have identical molecular formulas, their structures exhibit significant differences originating from different pH values used in the synthesis. Interestingly, one-dimensional (1D) channels exist in the 3D frameworks of 4 and 5; each channel is fabricated through interweaving left- and right-hand triple-stranded helixes. The explorations of magnetic properties of 2 and 5 were carried out. The luminescent investigations reveal that 2 exhibits characteristic luminescence of Tb3+, and the lifetime of the transition 5D4 → 7F5 is about 0.78 ms when excited at λex = 296 nm.
Dynamic Service Reallocation in NFV-based Transport WDM Optical Networks (2018)

Future network services are expected to deliver additional functionalities besides connectivity. The Network Function Virtualization (NFV) paradigm provides the foundation for such concept. We propose a reallocation-based provisioning mechanism to enrich service provisioning architectures in NFV-based transport optical networks, achieving up to three orders of magnitude reductions in experienced blocking.
The ORF0 product of Potato leafroll virus is indispensable for virus accumulation (2001)

Using a cDNA expression cassette in combination with agroinoculation of potato leaf discs we have investigated the role the protein encoded by ORF0 of Potato leafroll virus (PLRV) and have shown its importance for virus accumulation. Two mutations introduced into ORF0 by site-directed mutagenesis prevented expression of the corresponding protein and completely abolished virus accumulation in plant cells. They did not, however, affect translation of ORF1 and ORF2. We therefore conclude that ORF0 of PLRV produces a protein essential for virus accumulation, a hitherto undescribed finding.
Enantioselective Gold-Catalyzed Pictet–Spengler Reaction (2019)

Cationic chiral Au(I) complexes catalyze asymmetric Pictet-Spengler reactions between tryptamines and arylaldehydes. The resulting tetrahydro-β-carbolines are obtained with wide functional group tolerance in high yield and with high enantioselectivities (up to 95%). Aldehydes bearing polar or protic functions are well tolerated. The reaction features a hitherto unknown C2-auration of the indole as the key step, supported by density functional theory calculations.
The effect of intermolecular interaction on excited states in p − DTS(FBTTH2)2 (2016)

Using optical spectroscopy in solution and thin film, and supported by quantum chemical calculations, we investigated the aggregation process of the donor-acceptor type molecule p-DTS(FBTTH2)2. We demonstrate that cooling a solution induces a disorder-order phase transition that proceeds in three stages analogous to the steps observed in semi-rigid conjugated polymers. By analyzing the spectra, we are able to identify the spectral signature of monomer and aggregate in absorption and emission. From this we find that in films, the fraction of aggregates is near 100% which is in contrast to films made from semi-rigid conjugated polymers.
A novel insect defensin mediates the inducible antibacterial activity in larvae of the dragonfly Aeschna cyanea (Paleoptera, Odonata) (1992)

The injection of low doses of bacteria into the aquatic larvae of dragonflies (Aeschna cyanea, Odonata, Paleoptera) induces the appearance in their hemolymph of a potent antibacterial activity. We have isolated a 38-residue peptide from this hemolymph which is strongly active against Gram-positive bacteria and also shows activity against one of the Gram-negative bacteria which was tested. The peptide is a novel member of the insect defensin family of inducible antibacterial peptides, which had so far only been reported from the higher insect orders believed to have evolved 100 million years after the Paleoptera. Aeschna defensin is more potent than defensin from the dipteran Phormia, from which its structure differs in several interesting aspects, which are discussed in the paper.
Analysis of channel estimation error for OFDM reception over severely time-dispersive channels (2010)

The accuracy of equalization in the demodulation of orthogonal frequency division multiplexing signals is directly dependent on the density of pilot carriers in the signal and the delay dispersion of the propagation channel. In this paper, the error introduced by an insufficient pilot density with respect to the channel delay dispersion is theoretically analyzed. An expression is derived for the average channel estimation error given an OFDM pilot density and channel power delay profile. Based on this expression, the effect of channel estimation error on the perceived signal-to-noise ratio in the receiver demodulation is approximated. Results of the theoretical analysis and approximation are compared to simulations of OFDM transmitted over time-dispersive channels.
Design and Implementation of the Digital Costas Loop Based on Software Defined Radio (2011)

The frequency offset is the main problem of the conventional SDR receiver for demodulation. In order to overcome this drawback, the new methods are applied to improve the conventional Costas loop which is used to extract carrier. Firstly, the integration and accumulator is designed to realize the function of low-pass filter, which takes up fewer hardware resources. Secondly, the more accurate arctangent phase detector is used to detect the phase. It replaces the multiplier phase detector, which only obtain the approximate phase difference. Based on these two improvements, the realization of each module about the improved loop is presented. In this paper, first of all, the designed algorithm is simulated on the plat of MATLAB and Modelsim. The simulation results show that the design in this paper is feasible and the method is very effective. Moreover the system has been implemented and tested using field programmable gate arrays (FPGA). The test results indicate that the system has many advantages, including the design structure is simple, the convergence speed and the stability are better, and it can eliminate the frequency offset effectively. Therefore, this system can be widely applied in the engineering.
Network Ingress Filtering: Defeating Denial of Service Attacks which employ IP Source Address Spoofing (2000)

Recent occurrences of various Denial of Service (DoS) attacks which have employed forged source addresses have proven to be a troublesome issue for Internet Service Providers and the Internet community overall.This paper discusses a simple, effective, and straightforward method for using ingress traffic filtering to prohibit DoS attacks which use forged IP addresses to be propagated from 'behind' an Internet Service Provider's (ISP) aggregation point.

Geographic variation among three isolated populations of the hadal amphipod Hirondellea gigas (Crustacea: Amphipoda: Lysianassoidea) (1993)

The relative homogeneity and cont~nuity of the deep sea may provide a habitat in which species can maintain widespread, genetically homogeneous populations.This study examines the lysianassoid amphipod Hirondellea gigas (Birstein & Vinogradov 1955) to determine whether populations from spatially-disjunct habitats in the deep sea maintain genetic homogeneity.H. gigas is a scavenger which rapidly responds to and consumes experimental baitfalls at depths of > 10000 m.It appears to be endemic to western Pacific trenches, having been collected only within the Kurile-Kanichatka, Japan, Izu-Bonin, Volcano, Yap, Mariana, Palau, and Philippine Trenches.To estimate the degree of isolation of populations from the last 3 trenches, morphological variation was quantified through a discriminant analysis of surficial morphometric characters.Discriminant classification results were compared to 'null-populations', generated using a bootstrap randomization procedure, to determine the significance of the discrimination.Variation was sufficient to allow 68.4 to 84.5 % of individuals to be correctly reclassified into their population using discriminant functions.Bootstrapped randomizations of the data indicate that the classification success was significantly greater than random.Results indicate that these geographically-isolated trench populations may have reduced levels of gene flow between them, causing them to diverge lnorphologically
IL-36{gamma} induction in the human female reproductive tract is microbe-dependent (P4009) (2013)

Several combinations of binders and absorbent additives were utilized to solidify a typical organic waste, API Separator sludge. The effectiveness of the materials was based on the waste leachability from the solidified samples. COD and TOC analyses were used to determine the organic content of the leachate samples.The ability of the COD and TOC analyses to assess waste leachability was limited. The inability of the COD and TOC tests to differentiate between organic compounds made the results difficult to interpret. This was due to organic contaminants from the solidification materials contributing to the COD and TOC contents of the leachates. Also, the COD test may have be influenced by reduced inorganic compounds contained in the flyash binder and the sludge. Representative samples for the TOC analysis were difficult to obtain for the leachates containing oils or suspended particles. It is recommended that the COD and TOC tests only be used as a screening method for determining solidified organic waste leachability and other methods need to be employed to obtain more accurate results.
