A Qualitative and Quantitative Analysis of Real Time Traffic Information Providers (2019)

Worldwide, traffic congestion is increasingly recognized as a serious public health and environmental concern. Besides, traffic jams cause large economic damages for companies and cities. Many efforts have been made to mitigate these issues. Attempts to reduce the amount of traffic congestion strongly depend on the availability of traffic information in real time. Multiple providers of such data exist. However, there is no generally accepted source that provides accurate and publicly available live traffic information. The goal of this study is to evaluate real time traffic data offered by web map service providers. Therefore, we first identify the most prominent providers and evaluate their range of services. Further, we collect actual data traces and perform a thorough comparison of their scope and granularity. Finally, in a real world case study, we analyze the predicted travel duration for the selected providers. The results indicate not only that the range of services varies widely among traffic information providers but also the travel time predictions diverge.
Enantioseparations Using Cellulose Tris(3,5-dichlorophenylcarbamate) During High-performance Liquid Chromatography with Analytical and Capillary Columns: Potential for Screening of Chiral Compounds (2000)

The appropriate selection of the mobile phase facilitated the use cellulose tris(3,5-dichlorophenylcarbamate (CDCPC) as a chiral stationary phase (CSP) during high-performance liquid chromatography (HPLC). A preliminary evaluations of this material indicated its very high chiral resolving ability toward many analytes of different chemical and pharmacological groups. Some chemicals and drugs containing two centers of chirality were also successfully resolved into all possible stereoisomers. The applicability of CDCPC for enantioseparations in capillary liquid chromatography was also shown giving promising prospects for the screening of novel biologically active compounds (which may be also synthesized based on combinatorial strategies) for their enantiomeric composition.
Security Mechanisms Design of Automotive Gateway Firewall (2019)

<div class="section abstract"><div class="htmlview paragraph">Automotive security has become one of important topics in recent years under new automotive Electronic and Electrical Architecture (EEA). With the development of Intelligent Connected Vehicle (ICV), it has become possible to hack an automotive through in-vehicle networks. The introduction of Information Communications Technology (ICT) brings more risk threats to automotive. Researchers have shown that an attacker can easily tamper with many automotive functions via On-Board Diagnostic II (OBD-II) or In-Vehicle Infotainment (IVI). In order to protect automotive against malicious attacks, automotive security risks were analyzed and then security mechanisms based on network firewall were designed in this paper. Automotive network firewall is a security system that monitors and controls incoming and outgoing network traffics of automotive based on predetermined security rules. The main functions of network firewall include packet filter, anti-DoS and access control. Because of deferent security requirements of in-vehicle networks, CAN/FD and Ethernet were divided into two domains respectively. Packet filter mechanisms were designed to monitor CAN/FD, in which security level and time delay were considered. Ethernet firewall mechanisms were designed based on Stateful Packet Filter (SPF) technology. Beside packet filter mechanisms, anti-DoS and access control mechanisms were also designed. Security Real Time Operating System (SRTOS) was introduced to ensure lower layer security. Considering the ECU constraint, Hardware Security Module (HSM) is chosen to implement cryptography function. At last, proposed automotive network firewall were implemented base on a multicore MCU with HSM. The system is evaluated in several aspects such as packet throughput, time delay, anti-attack and memory usage. The evaluation results show that the automotive network firewall is effective and efficient.</div></div>
On the purported “backbone fluorescence” in protein three-dimensional fluorescence spectra (2016)

A peak in 3D-fluorescence spectra of proteins, often assigned to backbone emission, is shown to be due to aromatic residues.
Cooperative RTS/CTS MAC with relay selection in distributed wireless networks (2009)

This paper proposes a cooperative multiple access protocol based on the distributed coordination function (DCF) request-to-send/clear-to-send (RTS/CTS) scheme for distributed wireless networks. It answers three key questions concerning cooperation from the network perspective, namely when to cooperate, whom to cooperate with and how to protect cooperative transmissions. According to our protocol, the cooperation is initiated only if the direct transmission fails. An optimal relay node is selected in a distributed manner according to instantaneous relay channel conditions without prior information or extra signaling among relay candidates in the network. An additional three-way handshake is introduced to protect cooperative retransmissions against the hidden terminal problem. Both analysis and simulation results show that significant improvement in throughput and packet delivery rate can be achieved using the proposed cooperative protocol.
Effects of endothelial nitric oxide synthase gene expression on the tumor biology of human oral carcinoma SCC-25 cells. (1998)

Stable transfection of endothelial nitric oxide synthase (eNOS) cDNA in human oral carcinoma SCC-25 cells was performed. Two eNOS-expressing clones were isolated, and both were shown to have increased eNOS expression as assayed by Northern and Western analyses. Furthermore, a nitrite assay indicated that nitric oxide production in eNOS-transfected cells was increased. The growth rate and plating efficiency of eNOS-transfected cells in vitro were lower than that of the wild-type parental or vector control-transfected cells as assayed by growth curves, [3H]thymidine incorporation, and standard plating efficiency assays in L-arginine-rich medium. However, when these cancer cells were inoculated into nude mice, tumor size of eNOS-transfected cells was smaller during the first 25 days but increased later as compared to tumor size of parental and vector control-transfected cells. It is not clear whether the later increase in tumor size was due to an increase in SCC-25 cancer cell proliferation, normal stromal cell proliferation, or both. These results show significant effects of overexpression of eNOS on tumor growth in vitro and in vivo.
Tailoring the parameters of nanohole arrays in gold films for sensing applications (2007)

Subwavelength hole arrays in metal films have the potential to exhibit narrow and high refractive index (RI) sensitive transmission features. We have previously demonstrated that such features can arise from the coupling between Wood anomalies (WAs) and surface Plasmon polaritons (SPPs) on opposite sides of the metal film, the "WA-SPP" effect. Rigorous coupled-wave analysis (RCWA) calculations on a 2D model, which are shown to give WA-SPP features very similar to that of 3D Finite-Difference Time- Domain (FDTD) calculations, are performed to determine how system parameters influence the strength of the WA-SPP effect. Herein we show that the optimum values for the film thickness and hole diameter are 45 and 175 nm, respectively.
Size-Controlled Synthesis and Growth Mechanism of Monodisperse Tellurium Nanorods by a Surfactant-Assisted Method (2003)

This article describes a surfactant-assisted approach to the size-controlled synthesis of uniform nanorods of trigonal tellurium (t-Te). These nanorods were grown from a colloidal dispersion of amorphous Te (a-Te) and t-Te nanoparticles at room temperature, which was first formed through the reduction of (NH4)2TeS4 by Na2SO3 in aqueous solution at 80 degrees C. Nuclei formed in the reduction process had a strong tendency to grow along the [001] direction due to the inherently anisotropic structure of t-Te. The formation of Te nanorods could be ascribed to the confined growth through the surfactant adsorbing on the surfaces of the growing Te particles. By employing various surfactants in the synthesis system, Te nanorods with well-controlled diameters and lengths could be reproducibly produced by this method. Both the diameters and lengths of nanorods decreased with the increase of the alkyl length and the polarity of the surfactants. Te nanorods could also be obtained in mixed surfactants, where the different surfactants were used to selectively control the growth rates of different crystal planes. We also observed that the as-synthesized nanorods with uniform size could be self-assembled into large-area smecticlike arrays.
Fc-engineered antibodies with immune effector functions completely abolished (2021)

Elimination of the binding of immunoglobulin Fc to Fc gamma receptors (FcγR) is highly desirable for the avoidance of unwanted inflammatory responses to therapeutic antibodies and fusion proteins. Many different approaches have been described in the literature but none of them completely eliminates binding to all of the Fcγ receptors. Here we describe a set of novel variants having specific amino acid substitutions in the Fc region at L234 and L235 combined with the substitution G236R. They show no detectable binding to Fcγ receptors or to C1q, are inactive in functional cell-based assays and do not elicit inflammatory cytokine responses. Meanwhile, binding to FcRn, manufacturability, stability and potential for immunogenicity are unaffected. These variants have the potential to improve the safety and efficacy of therapeutic antibodies and Fc fusion proteins.
Which patients are prescribed inhaled anti-asthma drugs? (1994)

Inhaled steroid and bronchodilator prescribing have age-related and gender-related prevalences. Treatment for respiratory diagnoses varies with patient age and gender, and with the diagnosis. Prescribing differences between practices are attributable to variation in both diagnostic rates for respiratory disease and therapeutic intervention patterns. For asthma patients study practices show consensus in approach, perhaps illustrating the value of clear guidelines for asthma prescribing.
A parasitism gene from a plant‐parasitic nematode with function similar to <i>CLAVATA3/ESR (CLE)</i> of <i>Arabidopsis thaliana</i> (2005)

SUMMARY The Hg-SYV46 parasitism gene is expressed exclusively in the dorsal oesophageal gland cell of parasitic stages of the soybean cyst nematode, Heterodera glycines, and it encodes a secretory protein that contains a C-terminal motif of the CLAVATA3/ESR-related (CLE) family in Arabidopsis thaliana. In shoot and floral meristems of Arabidopsis, the stem cells secret CLV3, a founding member of the CLE protein family, that activates the CLV1/CLV2 receptor complex and negatively regulates WUSCHEL expression to restrict the size of the stem cell population. Mis-expression of Hg-SYV46 in Arabidopsis (ecotype Columbia-0) under control of the CaMV35S promoter resulted in a wus-like phenotype including premature termination of the shoot apical meristem and the development of flowers lacking the central gynoecium. The wus-like phenotype observed was similar to reports of over-expression of CLV3 and CLE40 in Arabidopsis, as was down-regulation of WUS expression in the shoot apices of 35S::Hg-SYV46/Col-0 plants. Expression of 35S::Hg-SYV46 in a clv3-1 mutant of Arabidopsis was able partially or fully to rescue the mutant phenotype, probably dependent upon localization and level of transgene expression. A short root phenotype, as reported for over-expression of CLV3, CLE40 and CLE19 in roots, was also produced in primary 35S::Hg-SYV46/Col-0 transgenic plants. The results suggest a functional similarity of HG-SYV46 to plant-secreted CLE ligands that may play a role in the differentiation or division of feeding cells induced in plant roots by parasitic nematodes.
Epithelial-mesenchymal transition in the pathogenesis of pterygium (2008)

A pterygium is a wing-shaped, fibrovascular conjunctival outgrowth, invading centripetally into the clear cornea, and its incidence is associated with sun exposure (ultraviolet radiation). We investigated whether epithelial-mesenchymal transition (EMT) is involved in the pathogenesis of pterygium. Histopathology showed aberrant fibrotic proliferation beneath the pterygium epithelium, with epithelial processes extending into the stroma. Transmission electron microscopy revealed the dissociation of epithelial cells, which were surrounded by activated fibroblast-like cells. Characteristic downregulation of E-cadherin and intranuclear accumulation of β-catenin and lymphoid-enhancer-factor -1 in pterygial epithelium were also observed by immunohistology. Interestingly, epithelial cells extending into the stroma were positive for both α-SMA/Vimentin and cytokeratin 14. Snail and Slug were immunopositive in the nuclei of pterygial epithelial cells, but not in normal corneal epithelial cells. These results suggested that EMT of basal epithelial cells may play a key role in the pathogenesis of pterygium.

The TMS320 family of digital signal processors (1987)

This paper begins with a discussion of the characteristics of digital signal processing, which are the driving force behind the design of digital signal processors. The remainder of the paper describes the three generations of the TMS320 family of digital signal processors available from Texas Instruments. The evolution in architectural design of these processors and key features of each generation of processors are discussed. More detailed information is provided for the TMS320C25 and TMS320C30, the newest members in the family. The benefits and cost-performance tradeoffs of these processors become obvious when applied to digital signal processing applications, such as telecommunications, data communications, graphics/image processing, etc.
WMe<sub>6</sub> Tamed by Silica: ≡Si–O–WMe<sub>5</sub> as an Efficient, Well-Defined Species for Alkane Metathesis, Leading to the Observation of a Supported W–Methyl/Methylidyne Species (2013)

The synthesis and full characterization of a well-defined silica-supported ≡Si-O-W(Me)5 species is reported. Under an inert atmosphere, it is a stable material at moderate temperature, whereas the homoleptic parent complex decomposes above -20 °C, demonstrating the stabilizing effect of immobilization of the molecular complex. Above 70 °C the grafted complex converts into the two methylidyne surface complexes [(≡SiO-)W(≡CH)Me2] and [(≡SiO-)2W(≡CH)Me]. All of these silica-supported complexes are active precursors for propane metathesis reactions.
End-to-End Neural Diarization: Reformulating Speaker Diarization as Simple Multi-label Classification (2020)

The most common approach to speaker diarization is clustering of speaker embeddings. However, the clustering-based approach has a number of problems; i.e., (i) it is not optimized to minimize diarization errors directly, (ii) it cannot handle speaker overlaps correctly, and (iii) it has trouble adapting their speaker embedding models to real audio recordings with speaker overlaps. To solve these problems, we propose the End-to-End Neural Diarization (EEND), in which a neural network directly outputs speaker diarization results given a multi-speaker recording. To realize such an end-to-end model, we formulate the speaker diarization problem as a multi-label classification problem and introduce a permutation-free objective function to directly minimize diarization errors. Besides its end-to-end simplicity, the EEND method can explicitly handle speaker overlaps during training and inference. Just by feeding multi-speaker recordings with corresponding speaker segment labels, our model can be easily adapted to real conversations. We evaluated our method on simulated speech mixtures and real conversation datasets. The results showed that the EEND method outperformed the state-of-the-art x-vector clustering-based method, while it correctly handled speaker overlaps. We explored the neural network architecture for the EEND method, and found that the self-attention-based neural network was the key to achieving excellent performance. In contrast to conditioning the network only on its previous and next hidden states, as is done using bidirectional long short-term memory (BLSTM), self-attention is directly conditioned on all the frames. By visualizing the attention weights, we show that self-attention captures global speaker characteristics in addition to local speech activity dynamics, making it especially suitable for dealing with the speaker diarization problem.
Inhibitors of Serine Proteinases from Blood Coagulation Cascade - View on Current Developments (2012)

The importance of Factor Xa and thrombin in thrombosis and haemostasis is widely appreciated in the last years. This understanding logically leads to the concept of Factor Xa and thrombin inhibition as viable and attractive target for the antithrombotic therapy. The following review collects and summarizes information on numerous anticoagulant peptides, proteins, chemical compounds and low molecular weight fragment analogues of natural peptides isolated from hematophagous. Unfortunately, not much data from clinical trials of direct Factor Xa and thrombin inhibitors is available in the present moment. The current information reveals that Factor Xa and thrombin inhibition is a promising approach for prevention and treatment of hemostatic impairments. The synthesis of a low molecular weight synthetic peptide mimetics could be a key point in the fight against many diseases related to haemostatic disorders.
Transplant strategies for patients with myelodysplastic syndromes (2006)

Modifications of transplant conditioning regimens have reduced transplant-related mortality, allowing successful hematopoietic cell transplantation in increasingly older patients. Graft versus host disease, both acute and chronic, and posttransplant relapse remain challenging problems.
An Efficient and Dynamic Semantic-Aware Multikeyword Ranked Search Scheme Over Encrypted Cloud Data (2019)

Traditional searchable encryption schemes adopting the bag-of-words model occupy massive space to store the document set's index, where the dimension of the document vector is equal to the scale of the dictionary. The bag-of-words model also ignores the semantic information between keywords and documents, which could return non-relevant search results to users. The neutral-network based natural language processing method - Doc2Vec model use word's and paragraph's context information to extract documents' features. The features contain latent semantics information and can measure the similarity between documents. In this paper, we adopt the Doc2Vec model to achieve a semantic-aware multikeyword ranked search scheme. Doc2Vec model uses the distributed representation of words and documents with a modest dimensionality of vectors while trained on a dataset with a few hundred of millions of words. Documents' distributed representations are extracted as documents feature vector by Doc2Vec model and utilized as the search index. The features of the queried keywords are also extracted as the query feature vector, and the secure inner product operation is adopted to achieve privacy-preserving semantic search with the query feature vector and index. Our scheme can support dynamic update on the document set with Doc2Vec model. The experiment on a real-world dataset shows that the fixed-length feature vector can improve the time and space efficiency on the semantic-aware search.
Biodiesel Production with Heterogeneous Sulfonic Acid-Functionalized Mesostructured Catalysts (2008)

Transesterification of refined and crude vegetable oils was carried out with a sulfonic acid-modified mesostructured catalyst. This catalyst has yielded fatty acid methyl ester (FAME) purity over 95 wt % for oil conversion close to 100% under best reaction conditions (temperature 180 °C, methanol/oil molar ratio 10, and catalyst loading 6 wt % with regard to the amount of oil). Interestingly, high methanol concentration leads to a detrimental effect on the catalyst activity. Regardless of the presence of free fatty acids, the sulfonic acid-modified mesostructured catalyst showed high activity toward simultaneous esterification and transesterification. These sulfonated mesostructured materials are promising catalysts for preparation of biodiesel, but some aspects related to the tuning of the adsorption properties of the silica surface and the enhancement of the catalyst’s reusability must be addressed in future work.
Reconfiguration between soft output Viterbi and log Maximum A Posteriori decoding algorithms (2000)

In third generation mobile communication standards (UMTS, cdma2000 and Japanese W-CDMA) different kinds of encoding are specified for different types of services and channels-convolutional, turbo, Reed-Solomon and CRC. Decoding may use any suitable algorithm, with prime candidates being versions of the Viterbi algorithm (with soft or hard output), and the maximum a posteriori probability algorithm, with its derivatives log-MAP and max-log-MAP. It would be advantageous to be able to select the optimum algorithm in any circumstance. The paper examines the reconfiguration between SOVA and log-MAP decoding algorithms. The performance of log-MAP is higher than SOVA, but with more complexity and delay. The two algorithms are analysed into component operations and blocks and the common parts are identified.
A statistical analysis of the effect of substrate utilization and shear stress on the kinetics of biofilm detachment (1993)

One of the least understood processes affecting biofilm accumulation is detachment. Detachment is the removal of cells and cell products from an established biofilm and subsequent entrainment in the bulk liquid. The goal of this research was to determine the effects of shear stress and substrate loading rate on the rate of biofilm detachment. Monopopulation Pseudomonas aeruginosa and undefined mixed population biofilms were grown on glucose in a RotoTorque biofilm reactor. Three levels of shear stress and substrate loading rate were used to determine their effects on the rate of detachment. Suspended cell concentrations were monitored to determine detachment rates, while other variables were measured to determine their influence on the detachment rate. Results indicate that detachment rate is directly related to biofilm growth rate and that factors which limit growth rate will also limit detachment rate. No significant influence of shear on detachment rate was observed.A new kinetic expression that incorporates substrate utilization rate, yield, and biofilm thickness was compared to published detachment expressions and gives a better correlation of data obtained both in this research and from previous research projects, for both mono- and mixed-population biofilms.
Automated cable coupling analysis software for EMC prediction (2003)

Electromagnetic (EM) coupling between cables containing shielded twisted pairs can cause system degradation, i.e., powerline noise induced onto cables used for communication. Software that uses mathematical models of differential- and common-mode coupling between shielded twisted pairs is described. The differential-mode coupling model is derived from Ampere's law and the Biot-Savart law. The common-mode coupling model is based on the percent imbalance in cable-shield current and inductance due to cable-shield distance from a ground plane. EM data tables and a set of routines using these models were generated using structured query language embedded in Fortran. A novel approach was taken to ensure correct results and reduce user error: the program accesses a large existing knowledge base of cable electrical and physical properties, requiring only cable designators and positions from a user to obtain an interference evaluation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
