A security protocol intended to ease QoS management in IP networks (2004)

Abstract Many research projects and implementations related to QoS (Quality of Service) management technologies for providing stable network services have been undertaken. To perform QoS management, traffic classes are required. Generally, traffic is classified by setting priorities for packets, and the methods of setting those priorities include passive admission control in which clients set priorities and active admission control in which network edge routers check traffic and set priorities. To perform active admission control, identification information such as a TCP or UDP header must be inspected. However, with existing security protocols such as ESP (Encapsulating Security Payload) or SSH (Secure Shell), these kinds of information cannot be inspected because they are encrypted. Based on the point of view that active admission control should be performed to simplify QoS management of IP networks, the authors of this paper propose a security protocol named ESPQ (ESP considered QoS) for constructing active admission controllable packets and investigate the stability of that protocol. They also perform implementation experiments to show that existing control equipment such as routers can perform QoS management of ESPQ packets. © 2004 Wiley Periodicals, Inc.

<i>Candida</i>Infections: An Overview (1987)

The range of human infections caused by the yeast Candida albicans and a handful of related species is considerable. They range from relatively trivial conditions such as oral and genital thrush to fatal, systemic superinfections in patients who are already seriously ill with other diseases. Interest in Candida infections, and in C. albicans in particular, has become huge in recent years as fatal infections have become more prevalent and new Candida-based pathologies have been recognized. There is now even a large pseudoscientific cult based on the notion that chronic allergy to Candida can cause all sorts of common illnesses. The medical importance of Candida infections and the scientific value of C. albicans as a model for fungal cellular development have stimulated enormous advances in our understanding of the epidemiology of candidosis, pathogenesis of the disease, and the genetics and biochemistry of C. albicans.
Selectivity is an Important Characteristic of Lipases (Acylglycerol Hydrolases) (1990)

Lipases are enzymes that usually hydrolyze acylglycerols, but will hydrolyze the carboxylic esters in many other compounds. They also catalyze esteriftcations and transesterifications. In addition to specificity for carboxylic esters, the lipases are selective for lipid classes and show selectivity for primary vs. secondary alcohols (positional or regio-), fatty acids, enantiomers (chirality of either the acid or alcohol residue) and combinations of these. Uses of the enzymes have depended to some extent on regio- and fatty acid selectivities. Newer applications, such as ester synthesis and asymmetric hydrolysis, may not be based on selectivities. Factors affecting selectivities are discussed and some areas for research are mentioned.
Faster set intersection with SIMD instructions by reducing branch mispredictions (2014)

Set intersection is one of the most important operations for many applications such as Web search engines or database management systems. This paper describes our new algorithm to efficiently find set intersections with sorted arrays on modern processors with SIMD instructions and high branch misprediction penalties. Our algorithm efficiently exploits SIMD instructions and can drastically reduce branch mispredictions. Our algorithm extends a merge-based algorithm by reading multiple elements, instead of just one element, from each of two input arrays and compares all of the pairs of elements from the two arrays to find the elements with the same values. The key insight for our improvement is that we can reduce the number of costly hard-to-predict conditional branches by advancing a pointer by more than one element at a time. Although this algorithm increases the total number of comparisons, we can execute these comparisons more efficiently using the SIMD instructions and gain the benefits of the reduced branch misprediction overhead. Our algorithm is suitable to replace existing standard library functions, such as std::set_intersection in C++, thus accelerating many applications, because the algorithm is simple and requires no preprocessing to generate additional data structures. We implemented our algorithm on Xeon and POWER7+. The experimental results show our algorithm outperforms the std::set_intersection implementation delivered with gcc by up to 5.2x using SIMD instructions and by up to 2.1x even without using SIMD instructions for 32-bit and 64-bit integer datasets. Our SIMD algorithm also outperformed an existing algorithm that can leverage SIMD instructions.

The Application of Deep Convolutional Denoising Autoencoder for Optical Character Recognition Preprocessing (2017)

The process of converting physical documents into digital texts generally requires a scanner tool to obtain high-quality document images. These high quality images will be read by OCR software to get digital text results. The weakness of this method is that OCR software requires a high quality document with low blur noise and no parallax in the image to have high accuracy. We developed an application to increase the document image quality with the help of Deep Convolutional Denoising Autoencoder, afterwards read by the OCR application. The final product of this program is a digital text converted from a document image which has been taken from a smartphone. There is an increase in accuracy using this application by 26.68% in a blurred image compare to standard Tesseract OCR and outperformed Simple OCR in average accuracy testing.
Endosaccular Flow Disruption: A New Frontier in Endovascular Aneurysm Management (2019)

Flow modification has caused a paradigm shift in the management of intracranial aneurysms. Since the FDA approval of the Pipeline Embolization Device (Medtronic, Dublin, Ireland) in 2011, it has grown to become the modality of choice for a range of carefully selected lesions, previously not amenable to conventional endovascular techniques. While the vast majority of flow-diverting stents operate from within the parent artery (ie, endoluminal stents), providing a scaffold for endothelial cells growth at the aneurysmal neck while inducing intra-aneurysmal thrombosis, a smaller subset of endosaccular flow disruptors act from within the lesions themselves. To date, these devices have been used mostly in Europe, while only utilized on a trial basis in North America. To the best of our knowledge, there has been no dedicated review of these devices. We therefore sought to present a comprehensive review of currently available endosaccular flow disruptors along with high-resolution schematics, presented with up-to-date available literature discussing their technical indications, procedural safety, and reported outcomes.
Novel human ocular glutathione S-transferases with high activity toward 4-hydroxynonenal. (1995)

The results indicate that hGST 5.8 isozyme(s) distinct from the alpha, mu, and pi classes of GSTs, are differentially expressed in human ocular tissues and may play an important role in protective mechanisms against endogenous toxicants generated during lipid peroxidation.
Somatic mutations of the von Hippel-Lindau tumor suppressor gene in sporadic central nervous system hemangioblastomas. (1994)

Hemangioblastoma is one of the benign tumors in the central nervous system. It is often associated with the von Hippel-Lindau (VHL) disease, a well known hereditary tumor syndrome. It is believed that inactivation of both alleles of VHL tumor suppressor gene is essential in the tumorigenic processes in hemangioblastomas associated with VHL disease. The molecular basis for the development of sporadic hemangioblastomas is not known. Here, we analyzed 13 cases of primary sporadic hemangioblastomas for somatic mutations of VHL gene with single strand conformational polymorphism analyses of the tumor DNAs. We detected abnormal single strand conformational polymorphism pattern in 7 tumors (54%). Of these 7 possibly mutated tumors, we successfully characterized 3 tumors by direct sequencing. We were unable to sequence 4 tumors because of the poor quality of DNA obtained from paraffin blocks. Somatic mutations in the 3 tumors were 2 missense mutations and 1 microdeletion. These mutations were observed in 1 tumor in exon 1 and 2 tumors in exon 2. Our results suggest that mutations of VHL tumor suppressor gene are involved in the development of at least 20% of sporadic central nervous system hemangioblastomas.
Tumor-specific Expression of MicroRNA-26a Suppresses Human Hepatocellular Carcinoma Growth via Cyclin-dependent and -independent Pathways (2011)

MicroRNA-26a (miR-26a) is a tumor suppressor that is reduced in hepatocellular carcinoma (HCC). Increasing evidence indicates that the liver is a hormone-responsive organ like the breast. The purpose of this study was to investigate whether miR-26a, regulated by a human α-fetoprotein (hAFP) and human telomerase reverse transcriptase (hTERT) dual promoter, could be specifically expressed in liver tumor cells to suppress their growth and to clarify whether estrogen receptor-α (ERα) is regulated by miR-26a and involved in the HCC process. Our data show that miR-26a expression driven by a hAFP-TERT dual promoter was tumor-specific and decreased the viability of tumor cells by regulating ERα, progesterone receptor (PR) and P53 except for cyclin D2 or cyclin E2 in vitro and in vivo. Our data also show that estradiol (E2) promotes the growth of liver cancer cells similar to breast cancer cells partly via the E2-ERα pathway and that miR-26a significantly down regulates ERα and prevents the stimulation of hepatoma cell growth by E2. These data suggest that ERα, which is regulated by miR-26a, is important for liver tumor cell growth. Moreover, hAFP-TERT dual promoter-mediated miR-26a expression could specifically exert potential antitumor activity and provide a novel targeting approach for cancer therapy.
Accelerated Diabetic Nephropathy in Mice Lacking the Peroxisome Proliferator–Activated Receptor α (2006)

Peroxisome proliferator-activated receptor (PPAR)alpha, a member of the ligand-activated nuclear receptor superfamily, plays an important role in lipid metabolism and glucose homeostasis and is highly expressed in the kidney. The present studies were aimed at determining the role of PPARalpha in the pathogenesis of diabetic nephropathy using PPARalpha-knockout mice and cultured murine mesangial cells. Diabetes was induced using a low-dose streptozotocin protocol in 8-week-old male 129 SvJ PPARalpha-knockout and wild-type mice. Diabetic PPARalpha-knockout and wild-type mice developed elevated fasting blood glucose (P < 0.001) and HbA1c levels (P < 0.001). Renal functional and histopathological changes in diabetic and nondiabetic PPARalpha-knockout and wild-type mice were evaluated after 16 weeks of hyperglycemia. PPARalpha immunostaining of the cortical tubules of diabetic wild-type mice was elevated by hyperglycemia. In diabetic PPARalpha-knockout mice, renal disease with accompanying albuminuria, glomerular sclerosis, and mesangial area expansion was more severe than in diabetic wild-type mice (P < 0.05) and was accompanied by increased levels of serum free fatty acids and triglycerides (P < 0.01). Furthermore, they exhibited increased renal immunostaining for type IV collagen and osteopontin, which was associated with increased macrophage infiltration and glomerular apoptosis. There were no significant differences in these indexes of renal disease between nondiabetic PPARalpha-knockout and wild-type mice and diabetic PPARalpha wild-type mice. In vitro studies demonstrated that high glucose levels markedly increased the expression of type IV collagen, transforming growth factor-beta1, and the number of leukocytes adherent to cultured mesangial cells. Adherence of leukocytes was inhibited by the PPARalpha agonist fenofibrate. Taken together, PPARalpha deficiency appears to aggravate the severity of diabetic nephropathy through an increase in extracellular matrix formation, inflammation, and circulating free fatty acid and triglyceride concentrations. PPARalpha agonists may serve as useful therapeutic agents for type 1 diabetic nephropathy.
Tailoring Hierarchical Zeolites with Designed Cationic Surfactants and Their High Catalytic Performance (2017)

Three hierarchical porous zeolites (H-*BEA, H-MTW, and H-*MRE) were successfully synthesized with the assistance of designed cationic surfactants under hydrothermal synthesis conditions. The as-synthesized zeolite samples can be easily regulated by changing the number of long hydrophobic n-alkyl chains. Also, we investigated the relationship between the length of the surfactant and the formation of the microporous structure of the zeolite. Furthermore, the alkylation of benzene with propene was performed as a probe reaction to evaluate the catalytic performance of the synthesized hierarchical zeolites. The resulting materials were characterized by using a complementary combination of techniques, that is, X-ray powder diffraction, N<sub>2</sub> adsorption-desorption isotherms, scanning electron microscopy, transmission electron microscopy, Fourier transform IR spectroscopy, <sup>28</sup> Si and <sup>27</sup> Al MAS NMR spectroscopies, thermogravimetric analysis, and computer simulation. These analysis results indicated that quaternary ammonium surfactants acted as organic structure-directing agents (OSDAs) in the formation of these hierarchical zeolite samples, whether the surfactant had long hydrophobic tail groups or not. The simulation results indicated that the organic molecules with no long hydrophobic chain could lead to the synthesis of zeolite through charge control, and the hydrophobic molecules with long hydrophobic chains could form zeolites through orbital control. These hierarchical zeolites showed improved catalytic activity towards the industrially relevant alkylation of benzene with propene compared with conventional zeolites with the same frameworks. More importantly, the success of using quaternary ammonium surfactants with no hydrophobic n-alkyl tail group in the synthesis of hierarchically structured mesoporous zeolites provides a new pathway for the synthesis of hierarchical porous materials by a soft-templating method.
Discrete Deformable Model Guided by Partial Active Shape Model for TRUS Image Segmentation (2010)

Automatic prostate segmentation in transrectal ultrasound (TRUS) images is highly desired in many clinical applications. However, robust and automated prostate segmentation is challenging due to the low SNR in TRUS and the missing boundaries in shadow areas caused by calcifications or hyperdense prostate tissues. This paper presents a novel method of utilizing a priori shapes estimated from partial contours for segmenting the prostate. The proposed method is able to automatically extract prostate boundary from 2-D TRUS images without user interaction for shape correction in shadow areas. During the segmentation process, missing boundaries in shadow areas are estimated by using a partial active shape model, which takes partial contours as input but returns a complete shape estimation. With this shape guidance, an optimal search is performed by a discrete deformable model to minimize an energy functional for image segmentation, which is achieved efficiently by using dynamic programming. The segmentation of an image is executed in a multiresolution fashion from coarse to fine for robustness and computational efficiency. Promising segmentation results were demonstrated on 301 TRUS images grabbed from 19 patients with the average mean absolute distance error of 2.01 mm +/- 1.02 mm.
Interleukin-10 Inhibits Bone Resorption: A Potential Therapeutic Strategy in Periodontitis and Other Bone Loss Diseases (2014)

Periodontitis and other bone loss diseases, decreasing bone volume and strength, have a significant impact on millions of people with the risk of tooth loss and bone fracture. The integrity and strength of bone are maintained through the balance between bone resorption and bone formation by osteoclasts and osteoblasts, respectively, so the loss of bone results from the disruption of such balance due to increased resorption or/and decreased formation of bone. The goal of therapies for diseases of bone loss is to reduce bone loss, improve bone formation, and then keep healthy bone density. Current therapies have mostly relied on long-term medication, exercise, anti-inflammatory therapies, and changing of the life style. However there are some limitations for some patients in the effective treatments for bone loss diseases because of the complexity of bone loss. Interleukin-10 (IL-10) is a potent anti-inflammatory cytokine, and recent studies have indicated that IL-10 can contribute to the maintenance of bone mass through inhibition of osteoclastic bone resorption and regulation of osteoblastic bone formation. This paper will provide a brief overview of the role of IL-10 in bone loss diseases and discuss the possibility of IL-10 adoption in therapy of bone loss diseases therapy.
Fences and Deer-Damage Management: A Review of Designs and Efficacy (2006)

White-tailed deer (Odocoileus virginianus) may cause more damage than any other species of wildlife. These damages include crop loss, automobile and aviation collisions, disease transmission, environmental degradation, and destruction of ornamental plantings. One practical method of controlling deer damage is the use of exclusionary fences. The relatively high cost of labor and materials required to build effective fences has limited most applications to the protection of orchards, vegetable farms, other high-value resources, and mitigation of human health and safety risks. Improvements in fence technology resulting in less expensive, yet effective fences have expanded the use of fences to manage damage caused by deer. Fences typically installed to manage white-tailed deer damage include wire or plastic mesh, electrified high-tensile steel wire, and electrified polytape or polyrope fence. We reviewed the scientific literature on fencing to determine which fence designs would be the most effective for excluding deer in a variety of situations.
Medial Unicornpartmental Arthroplasty (1993)

One hundred twenty-one knees with medial compartment osteoarthrosis were treated by unicompartmental arthroplasty with the Oxford Knee. The strict selection criteria were (1) the presence of a functioning anterior cruciate ligament, (2) fully correctable deformity, and (3) full thickness of articular cartilage in the lateral compartment. The mean elapsed time from surgery was 44.4 months. One knee has required revision for a loose tibial component. The results at this stage are as acceptable as those of tricompartmental knee arthroplasty and better than those of high tibial osteotomy.
Does the Environmental Health Officer Have a Role in Relation to Hazardous Materials (1994)

The Environmental Health Officers have a very significant part to play whilst handling hazardous materials or dangerous goods. Hence they should have the basic understanding of what constitutes a hazardous material. They should also be aware of the State requirements in relation to dangerous goods in the workplace under the control of municipality.
Cellular structures for computation in the quantum regime (1999)

We present a data-processing scheme, a hybrid of existing cellular automata (CA) and gate array architectures, which is optimized for realization at the quantum scale. For classical computing, our CA-like external clocking avoids problems associated with existing ground-state relaxation schemes. For quantum computing, our architecture constitutes a paradigm whereby the algorithm is embedded in spatial, as opposed to temporal, structure; we discuss the consequences for algorithmic efficiency. Two potential physical realizations of the scheme are discussed.
Nasal Immunization with Homogenate and Peptide Antigens Induces Protective Immunity against <i>Trichinella spiralis</i> (2002)

Mice were successfully immunized against the intestinal nematode Trichinella spiralis by intranasal administration of a 30-mer peptide antigen with cholera toxin B. Immunized mice developed antigen-specific serum immunoglobulin G1, intestinal immunoglobulin A, and a type 2-biased cytokine response. Intranasal immunization therefore generates the Th2-mediated responses required for immunity against intestinal parasites.
Blockchain-base structures for a secure and operate network of semi-autonomous Unmanned Aerial Vehicles (2018)

Unmanned Aerial Vehicles - UAVs, or drones - are now being operated by several military forces and currently, to a more limited extent, by civilian organizations. These latter operations, however, may eventually expand to exceed, in number and diversity, those of the military. Further expected development in battery capacity, construction materials and software, especially regarding machine learning algorithms and drone integration, will definitely increase UAVs' autonomous. Unique risks associated with UAVs like risk of hackers' attacks to intercept the control are also increasing. More incidents likely will occur once regulations are finalized that encourage more use that is widespread. Such incidents could result in multi-million dollar claims against businesses, operators and manufacturers. Blockchain is the basis technology for cryptocurrencies. However, Blockchain can have far larger applications in the field of UAVs, because Blockchain is highly distributed and publically viewable system of sequentially linked cryptographically. This paper presents a concept of application, where each UAV in the UAVNet is a Blockchain node, has on-board functionality for creating and reading transactions from the block, as well as communication tools for exchanging transactions with other UAVs.
