BLAC (2010)

Several credential systems have been proposed in which users can authenticate to service providers anonymously. Since anonymity can give users the license to misbehave, some variants allow the selective deanonymization (or linking) of misbehaving users upon a complaint to a Trusted Third Party (TTP). The ability of the TTP to revoke a user’s privacy at any time, however, is too strong a punishment for misbehavior. To limit the scope of deanonymization, some systems have been proposed in which users can be deanonymized only if they authenticate “too many times,” such as “double spending” with electronic cash. While useful in some applications, such techniques cannot be generalized to more subjective definitions of misbehavior, for example, using such schemes it is not possible to block anonymous users who “deface too many Web pages” on a Web site. We present BLAC, the first anonymous credential system in which service providers can revoke the credentials of misbehaving users without relying on a TTP . Since revoked users remain anonymous, misbehaviors can be judged subjectively without users fearing arbitrary deanonymization by a TTP . Additionally, our construction supports a d-strikes-out revocation policy, whereby users who have been subjectively judged to have repeatedly misbehaved at least d times are revoked from the system. Thus, for the first time, it is indeed possible to block anonymous users who have “defaced too many Web pages” using our scheme.
Analysis of regional down-sampling methods for coding of omnidirectional video (2016)

In order to compress omnidirectional video clips, a projection onto a two-dimensional image plane is necessary. The most commonly used projection format is the equirectangular panoramic projection, which results into a significant amount of redundant samples in the polar areas. The redundant samples incur extra bitrate and increase the encoding/decoding time. In this paper, we study regional down-sampling (RDS) for achieving better compression and smaller encoding/decoding time for omnidirectional content. We extend the persistent RDS method applied equally to all pictures to be applied to selected pictures only in our proposed temporal RDS method and then compare the persistent and temporal RDS methods. The simulation results indicate that both the persistent and temporal RDS improve the rate-distortion (RD) performance compared to the conventional coding of equirectangular panoramas, while the temporal RDS method has less sequence-wise RD performance variation and slightly better RD performance on average when compared to the persistent RDS technique. Alongside the coding methods, we study spherical quality measurement methods for VR images/video and analyze the coding methods with these quality metrics. Moreover, we propose a uniformly sampled spherical quality metric in order to evaluate the coding distortion of omnidirectional videos.

Gastric epithelioid leiomyosarcoma: a curable gastric neoplasm. (1987)

This is the first case report of the preoperative diagnosis of a gastric epithelioid leiomyosarcoma by percutaneous needle biopsy. Preoperative diagnosis facilitated curative surgical resection. Patients may present without symptoms or may report symptoms of peptic ulcer disease or gastrointestinal bleeding. Upper gastrointestinal series is the most useful radiological tool for detecting these lesions. Ultrasound and CT play a useful role in documenting the origin of these large masses, as well as their spread. Endoscopy is being used with increasing frequency, but because these are submucosal lesions diagnosis cannot easily be made through the endoscope. Pathologically, these tumors can be subdivided histologically into a benign epithelioid leiomyoma and two varieties of malignant epithelioid leiomyosarcoma. Prognosis correlates with histological features. Complete surgical resection is the treatment of choice. Chemotherapy or radiotherapy have no proven efficacy in treating epithelioid leiomyosarcoma. Unlike most other gastric malignancies, a favorable prognosis follows successful resection.
Inflammatory links between obesity and metabolic disease (2011)

The obesity epidemic has forced us to evaluate the role of inflammation in the health complications of obesity. This has led to a convergence of the fields of immunology and nutrient physiology and the understanding that they are inextricably linked. The reframing of obesity as an inflammatory condition has had a wide impact on our conceptualization of obesity-associated diseases. In this Review, we highlight the cellular and molecular mechanisms at play in the generation of obesity-induced inflammation. We also emphasize how defining the immune regulation in metabolic tissues has broadened the understanding of the diversity of inflammatory responses.
Molecular Components of a Cell Death Pathway Activated by Endoplasmic Reticulum Stress (2003)

Alterations in Ca2+ homeostasis and accumulation of misfolded proteins in the endoplasmic reticulum (ER) cause ER stress that ultimately leads to programmed cell death. Recent studies have shown that ER stress triggers programmed cell death via an alternative intrinsic pathway of apoptosis that, unlike the intrinsic pathway described previously, is independent of Apaf-1 and cytochrome c. In the present work, we have used a set of complementary approaches, including two-dimensional gel electrophoresis coupled with matrix-assisted laser desorption ionization-time-of-flight mass spectrometry and nano-liquid chromatography-electrospray ionization mass spectrometry with tandem mass spectrometry, RNA interference, co-immunoprecipitation, immunodepletion of candidate proteins, and reconstitution studies, to identify mediators of the ER stress-induced cell death pathway. Our data identify two molecules, valosin-containing protein and apoptosis-linked gene-2 (ALG-2), that appear to play a role in mediating ER stress-induced cell death.
Efficacy of an ultraviolet-A lighting system for continuous decontamination of health care–associated pathogens on surfaces (2019)

We found that ultraviolet-A (UV-A) light exposure resulted in a modest reduction in recovery of methicillin-resistant Staphylococcus aureus (MRSA), Candida auris, bacteriophage MS2, and bacteriophage Phi X174, but not Clostridioides difficile spores, on steel disk carriers. Four hours of UV-A exposure from a ceiling light fixture resulted in a significant reduction in pathogenic microorganisms recovered from in-use medical equipment. These findings suggest that UV-A could be useful as a means to provide continuous low-level decontamination of surfaces in health care facilities.
Architecture Alternatives for Time-interleaved and Input-feedforward Delta-Sigma Modulators (2008)

This thesis provides architecture alternatives for delta-sigma modulators in two areas: high-speed operation based on time-interleaving and low-voltage environment by exploiting the input-feedforward concept. Parallelism based on time-interleaving can be used to increase the speed of delta-sigma modulators. A novel single-path time-interleaved architecture is derived and analyzed. Finite opamp gain and bandwidth result in a mismatch between the noise transfer functions of the internal quantizers which degrades the performance of the new modulator. Two techniques are presented to mitigate the mismatch problem: a hybrid topology where the first stage uses multiple integrators while the rest of the modulator uses a single path of integrators and a digital calibration method. The input-feedforward technique removes the input-signal component from the internal nodes of delta-sigma modulators. The removal of the signal component reduces the signal swing and distortion requirements for the opamps. These characteristics enable the reliable implementation of delta-sigma modulators in modern CMOS technology. Two implementation
Amplification of Uncultured Single-Stranded DNA Viruses from Rice Paddy Soil (2008)

Viruses are known to be the most numerous biological entities in soil; however, little is known about their diversity in this environment. In order to explore the genetic diversity of soil viruses, we isolated viruses by centrifugation and sequential filtration before performing a metagenomic investigation. We adopted multiple-displacement amplification (MDA), an isothermal whole-genome amplification method with phi29 polymerase and random hexamers, to amplify viral DNA and construct clone libraries for metagenome sequencing. By the MDA method, the diversity of both single-stranded DNA (ssDNA) viruses and double-stranded DNA viruses could be investigated at the same time. On the contrary, by eliminating the denaturing step in the MDA reaction, only ssDNA viral diversity could be explored selectively. Irrespective of the denaturing step, more than 60% of the soil metagenome sequences did not show significant hits (E-value criterion, 0.001) with previously reported viral sequences. Those hits that were considered to be significant were also distantly related to known ssDNA viruses (average amino acid similarity, approximately 34%). Phylogenetic analysis showed that replication-related proteins (which were the most frequently detected proteins) related to those of ssDNA viruses obtained from the metagenomic sequences were diverse and novel. Putative circular genome components of ssDNA viruses that are unrelated to known viruses were assembled from the metagenomic sequences. In conclusion, ssDNA viral diversity in soil is more complex than previously thought. Soil is therefore a rich pool of previously unknown ssDNA viruses.
Bonding to Ground Dentin by a Phenyl-P Self -etching Primer (1994)

Increasingly higher concentrations of Phenyl-P in 30% HEMA were used as dentin conditioners to improve the bonding of adhesive resins to smear layers. The maximum bond strength (10.4 MPa) was obtained at a concentration of 20% Phenyl-P. Transmission electron microscopy of fractured, lightly smeared, and compactly smeared dentin demonstrated that 20% Phenyl-P in 30% HEMA demineralized the dentin surface by partially dissolving mineral crystals from around collagen. When applied to smear layers, this resin system demineralized the smear layer and incorporated it into the applied resin which penetrated a short distance into the underlying dentin, thereby creating a hybrid layer that contained the original smear layer. This single-step conditioner/primer offers several advantages over previous bonding systems by permitting a single solution to serve as both a conditioner and a primer.
Tumor Necrosis Factor Levels in Serum and Bronchoalveolar Lavage Fluid of Patients with the Adult Respiratory Distress Syndrome (1991)

Tumor necrosis factor (TNF) was measured antigenically and functionally in serum and bronchoalveolar lavage fluid (BAL) of patients with ARDS and those at high risk for ARDS. Of 22 patients with ARDS, 14 had sepsis or serious infection as the major clinical predisposition, and 10 of 20 high-risk patients had sepsis or serious infection. Mean levels of TNF in serum of patients with ARDS and high risk showed a trend toward elevation but were not significantly higher than mean serum levels in normal subjects. Mean levels of TNF in BAL of ARDS patients (242 +/- 126 pg/ml) were significantly higher than in normal subjects (9 +/- 5 pg/ml), p less than 0.05. Antigenic levels of TNF were undetectable in approximately half the patients with ARDS or the high-risk state. Levels of TNF in BAL appeared to be highest in the first day of ARDS. There appeared to be no relationship between levels of TNF in serum or BAL and subsequent mortality. However, serum levels of TNF were significantly higher in septic patients than in nonseptic patients, whereas this difference was not apparent in BAL. These results show that functional and antigenic elevations of TNF are present in BAL and perhaps in serum of patients with ARDS or with the high-risk state.

Application of Electromechanical Impedance Technique for Engineering Structures: Review and Future Issues (2009)

The recent advent of highly durable engineering materials and the advancement of latest structural design theories have made possible the fabrication of more efficient engineering structures. However, the safety and reliability of these structures remains the primary challenge and concern for engineers. Especially, for those structures which involve human traffic and huge investments such as the aerospace structures and bridges. Therefore, there is a compelling need to have high-quality online structural health monitoring (SHM) of such structures. The development of a real-time, in-service, and smart material-based SHM method has recently attracted the interest of a large number of academic and industrial researchers. In the recent past, piezoceramic (PZT) transducer has evolved as an efficient smart material, which is usually employed in electro mechanical impedance (EMI) and guided ultrasonic wave propagation techniques. In EMI technique, a PZT transducer interact with the host structure to result in unique health signature, as an inverse function of structural impedance, when it is subjected to high-frequency structural excitations in the presence of electric field. Using the self-actuating and sensing capabilities of PZT transducers, the EMI models attempted to detect loadings on, and damages in, the structures to be monitored. This article reviews some of the advancements in the field of PZT-based SHM made over the past two decades in engineering structures. This article also provides an insight into the possible future work and improvements required for PZT-based EMI technique.

Signaling interactions of rapamycin combined with erlotinib in cervical carcinoma xenografts (2006)

Clinical trials using rapamycin analogues or HER1/epidermal growth factor receptor (EGFR) inhibitors show that each class of agent has activity against a range of human solid tumors. Because blockade of mitogen-activated protein kinase signaling occurs following HER1/EGFR inhibition in some cell types, we tested the combination of rapamycin and erlotinib in SiHa, Me180, and CaSki human cervical carcinomas xenografts in severe combined immunodeficient mice. In tissue culture, all three cell lines showed decreased phosphorylated S6 ribosomal protein and decreased phosphorylated extracellular signal-regulated kinase (ERK) following treatment with rapamycin and erlotinib, respectively. In SiHa tumors, suppression of phosphorylated S6 was induced by either drug alone, whereas phosphorylated ERK decreased with erlotinib, and enhancement of these effects was obtained with the combination. Continuous treatment of xenografts for 3 weeks led to significant tumor growth delay compared with vehicle control for rapamycin as single agent (P = 0.003) and greater for the combination (P = 0.04 versus rapamycin). Significant antiangiogenic effect was obtained in SiHa xenografts using the drugs together (measured by microvascular density and vascular endothelial growth factor plasma levels) but not for the single agents. Me180 and CaSki xenografts showed significant growth delay with rapamycin but not with erlotinib. Erlotinib treatment resulted in decreased phosphorylated ERK, associated with enhanced suppression of phosphorylated S6 and improved growth delay in Me180 but not in CaSki tumors. These results support the further clinical investigation of rapamycin and EGFR inhibitor combinations in anticancer therapy but highlight the problem of intertumoral heterogeneity in the prediction of in vivo response.
Whey Protein Lycosome Formulation Improves Vascular Functions and Plasma Lipids with Reduction of Markers of Inflammation and Oxidative Stress in Prehypertension (2012)

Parameters reflecting cardiovascular health and inflammation were studied in a pilot clinical trial conducted on 40 patients with prehypertension. The patients were treated with a new proprietary formulation of a whey protein (WP) isolate embedded into lycopene micelles (WPL) during a 1-month period. Control groups received lycopene or WP as a singular formulation or placebo pills for the same period of time. Combined WPL formulation of whey protein and lycopene has caused multiple favorable changes in the cardiovascular function (including a tendency to the reduced systemic blood pressure), the plasma lipid profile, and the inflammatory status of patients with prehypertension, whereas singular formulations of the compounds and placebo did not have such an effect. The reduction of plasma triglycerides and cholesterol fractions and almost two-fold decline in C-reactive protein (CRP) and inflammatory oxidative damage (IOD) levels as well as an increase in nitric oxide (NO), tissue oxygenation (StO(2)), and flow-mediated dilation values constitute the most significant benefit/outcome of the treatment with the combined formulation of whey protein and lycopene. The treatment did not affect the values of ankle-brachial index (ABI), body weight, and body mass index (BMI).
Phosphorylation of Transcription Factor CREB in Rat Spinal Cord after Formalin-Induced Hyperalgesia: Relationship to<i>c-fos</i>Induction (1997)

The involvement of cAMP-responsive element-binding protein (CREB) signaling in tissue injury-induced inflammation and hyperalgesia has been characterized by measuring phosphorylation of CREB at serine-133 (CREB Ser133) using a specific antibody. In the unstimulated state, unphosphorylated CREB was observed in most nuclei of spinal neurons except for motor neurons, where only a small portion of neurons were stained. A few dorsal root ganglion (DRG) neurons were also CREB-positive. After a unilateral injection of formalin into the hindpaw, a strong and bilateral phosphorylation of CREB Ser133 was induced, as assessed by both immunohistochemistry and Western blot. PhosphoCREB (pCREB)-positive neurons were found in laminae I, II, V, and X of spinal cord on both sides. CREB phosphorylation was very rapid and reached peak levels within 10 min of formalin treatment, whereas few pCREB-positive neurons were seen in unstimulated spinal cord. The induction of pCREB was predominantly postsynaptic, because only 5% of DRG neurons were labeled after inflammation. In contrast to CREB phosphorylation, the induction of c-Fos expression reached peak levels 2 hr after formalin treatment and c-Fos induction was mainly ipsilateral. Both formalin-evoked CREB phosphorylation and c-Fos expression in the spinal cord were suppressed by pretreatment with the NMDA receptor antagonist MK-801 (3.5 mg/kg, i.p.) or halothane anesthesia. These results suggest that CREB signaling may play a role in the long-term facilitation of spinal cord neurons after hyperalgesia. Furthermore, our results indicate that CREB phosphorylation may be necessary but not sufficient for c-fos induction.
Removal of air‐response by weighting inline and broadside CSEM/SBL data (2007)

The main goal in marine controlled source electromagnetic (CSEM) surveying for hydrocarbons, also called SeaBed Logging (SBL), is to detect and describe possible thin resistive layers within the conductive surroundings beneath the seabed. In shallow water the response from the air halfspace often masks the response from the subsurface. In this paper we present a new method for removing the air‐response from CSEM data. The spatial expressions for the air‐response derived by using asymptotic evaluation of the CSEM integrals show that the air‐response is predominantly a TE‐mode response which has similar behaviour for an inline and broadside source/receiver configuration. The subsurface data, on the other hand, differ substantially for the inline and broadside configurations. Thus, by summing or differencing a proper weighting of the inline and broadside data, the predominant air‐response can be removed from collected data. The method requires that both inline and broadside data are acquired.
