Robust control with decoupling performance for steering and traction of 4WS vehicles under velocity-varying motion (2000)

This paper mainly studies robust steering and traction of four-wheel steering (4WS) vehicles with varying velocity, mass, moment of inertia, and road-tire interaction. To this end, a nonlinear vehicle model is developed which both takes the acceleration and braking effects on the system dynamics into account and avoids using the complicated side force relation. Based on this model, a nonlinear input-output decoupling controller is first designed, by which the vehicle system can be decoupled into three two-order subsystems, i.e., the velocity subsystem controlled by the longitudinal acceleration/braking force, the lateral motion subsystem by the front steering angle, and the yaw motion subsystem by the rear steering angle, so that the load of the driver can be relieved. Especially, a new decoupling condition is derived. It is proved that a vehicle with the front wheel braking or rear wheel drive can always be decoupled provided it does not accelerate so fast or brake so hard that its front or rear wheels are lifted from the ground. Furthermore, in order to reduce the effects of the vehicle parameter variations on steering performance, a robust control scheme is proposed. The corresponding controller and observer gains can be obtained by solving two new Riccati algebraic equations. Meanwhile, by properly choosing the form of the observer, the robust controller does not destroy the decoupling structure of the longitudinal and yaw motions. The numerical simulation shows that the robust control with decoupling performance can improve safety and comfort of the vehicle driving.
Control of mobile communications with time-varying channels in heavy traffic (2002)

Consider the forward link of a system with K remote units and a single base transmitter with time varying connecting channels. Data to be transmitted to the remote units arrives according to some random process, and is queued according to its destination. Power is to be allocated to the K channels in a queue and channel state depend on way to minimize some cost criterion. The channel fading rate is fast and the bandwidth and data arrival rates are high. Owing to the high speed of the fading, arrival, and service rates, an asymptotic or averaging of the heavy traffic type method is promising. By heavy traffic, we mean that on the average there is little server idle time and spare power over the "average" requirements. Heavy traffic analysis eliminates inessential details and focuses on the fundamental issues of scaling and parametric dependencies. To illustrate the scope of the method, several models are considered, and more complicated systems are also treated.
New Strategies for Aspiration Pneumonia. (1997)

Aspiration pneumonia is associated with decreases in both swallowing and cough reflexes and is the most common cause of death in the elderly. Basal ganglia strokes might predispose these patients to develop pneumonia owing to reductions of both reflexes, resulting in frequent aspiration during sleep. An impairment of dopamine metabolism in the basal ganglia is observed in these patients and levodopa administration improves the impaired swallowing reflex. Both swallowing and cough reflexes are mediated by endogenous substance P (SP) released from vagal sensory nerves in the pharynx and upper airways. The addition of a low dose of capsaicin to liquid or food, which stimulates the release of SP, may help prevent aspiration pneumonia. Angiotensin-converting enzyme inhibitor decreases SP catabolism resulting in improvements in both reflexes. Oral care and the sitting position after meals may decrease aspiration pneumonia in the elderly.
Securing dynamic distributed storage systems from malicious nodes (2011)

We address the problem of securing distributed storage systems against adversarial node attacks. An important aspect of these systems is node failures over time, necessitating, thus, a repair mechanism in order to maintain a desired high system reliability. In such dynamic settings, an important security problem is to safeguard the system from a malicious adversary who may come at different time instances during the lifetime of the storage system to corrupt the data stored on some nodes. We provide upper bounds on the maximum amount of information that can be stored safely on the system in the presence of the adversary. For an important operating regime, which we call the bandwidth-limited regime, we show that our upper bounds are tight and provide explicit linear code constructions. Moreover, we provide a way to shortlist the malicious nodes and expurgate the system.
Systemic anti‐inflammatory fibrosis suppression in threatened trabeculectomy failure (2004)

Despite advances in surgical techniques and methods to control fibrosis, anti-inflammatory fibrosis suppression is a valuable tool to have available in the post-operative period for management of trabeculectomies that threaten failure. This regime produces a diffuse bleb, which has a very low risk of late infection or bleb perforation. It is recommend that this regime be added to the list of therapies that are considered when clinical features suggestive of a failing bleb are confronted early in the post-operative course.

Modelación molecular de cuatro penicilinas: bencilpenicilina, fenoximetilpenicilina, ampicilina y amoxicilina (2009)

Background: Penicillins differ structurally among themselves by the lateral chains. At the same time, they have differences in their pharmacological action that can be associated to modifications included in the betalactamic ring and/or effects localized in the same chains. Making it clear would be a contribution to the search of the most adequate structural and electronic characteristics to design better penicillins. Objective: To compare structural properties, density of the atomic charges and the frontier orbitals of four penicillins: bencylpenicillin, phenoxymethylpenicillin, ampicillin and amoxicillin. Method: The molecular structures were optimized with PM3 semiempirical calculi. The molecular properties were calculated according to the Density Functional Theory, at a B3LYP/6-31G(d) level. The density of the atomic charges and the frontier orbitals were analyzed. The effect of the substituents on the properties of the betalactamic ring was evaluated. Results: The structural parameters of the betalactamic ring do not change as consequence of the modifications in the lateral chain linked to carbon 6. The ring has a marked tendency to planarity. There are no variations in the density of the positive charge of the carbonylic carbon. Conclusions: The structures and electronic properties of the betalactamic ring, structural basis of these antibiotics, do not have significant modifications among modelled penicillins.
Improved positive surface modification resist process for 193-nm lithography (1998)

With increase in density of semiconductor devices, 193 nm lithography is promising to attain smaller feature size patterns. Surface imaging process is useful for this lithography in terms of large depth of focus and prevention from substrate reflection. As the surface imaging process, so far we developed positive surface modification resist process using CVD for various device patterns' fabrication. To solve the issues of selective polysiloxane layer formation and sensitivity, we have improved this positive surface modification resist process using a new polymer, poly(cyclohexyl p-styrenesulfonate-co-methyl methacrylate), and a new photobase generator, O-phenylacetyl acetonaphthone oxime. 0.15 micrometers pattern was successfully fabricated using the new process with improved sensitivity of 80 mJ/cm<SUP>2</SUP>.
SYNTEST: an environment for system-level design for test (1992)

The authors describe the design and implementation of SYNTEST, a system for the design of self-testable VLSI circuits from behavioral description. SYNTEST consists of several algorithmic synthesis tools for scheduling, testable allocation, and optimum test points selection. A key feature in SYNTEST is the tight interaction between the system tools: the scheduler, the allocator, and the test tool. The system uses a technology library for optimizing the original structure. All tools interact with each other as well with the user through an X graphical interface. This provides a better design environment and allows for more designer intervention. >
Use of an oxidized, regenerated cellulose absorbable adhesion barrier at laparoscopy. (1991)

The use of an oxidized, regenerated cellulose absorbable adhesion barrier has been shown to significantly reduce the incidence, extent and severity of postoperative gynecologic adhesions in a multicenter, randomized, prospective trial. Since an increasing proportion of gynecologic surgery is being performed laparoscopically, a prospective, multicenter, open-label study was initiated to evaluate the feasibility of using the adhesion barrier laparoscopically and to establish techniques for applying the barrier during those procedures. Eighty patients were studied: 42 underwent lysis of adhesions; 35, removal of endometriosis implants; and 14, tuboplasty/fimbrioplasty. An average of two pieces were placed per patient, with an average piece size of 3 x 3 cm and an average time required per piece of 2 minutes, 40 seconds. Seventy-five percent of the cases required less than three pieces each for application. Eighteen percent of the pieces were difficult to place, generally because of problems unfolding the material, excessive size or nonadherence. For similar reasons, replacement was necessary for 27 of 157 pieces placed (17.2%). The barrier can be applied with relative ease during operative laparoscopy. The fabric can be placed through either the suprapubic or umbilical sleeve, depending on the size of the piece of barrier required.
Running a group. (2006)

Self-help groups, e.g. for breast-feeding support or postnatal depression, can be an effective resource for clients. They can also be an effective use of professionals'time in primary care. A health visitor offers practical suggestions for starting and guiding a new group, including the need for professionals to think creatively and flexibly about group structures. The advice is to keep these simple, audit regularly and allow the groups to evolve.
Secure and resilient data printed on paper (2003)

Transmission and printing of sensitive information requires both data security, and protection against random and burst errors. This paper describes a technique that achieves two objectives: secure and reliable transmission of information; and integrity of the original information printed on paper. Information printed on paper is prone to burst and random errors. Resilience of the information to such errors is obtained by introducing redundancy into the original data using forward error correcting codes. We have selected a concatenation of a Reed-Solomon (RS) code, interleaved with a self-orthogonal majority decodable convolutional code. To measure the performance of the concatenated code, the bit error rate against signal to noise ratio of the code is compared with codes of equivalent rate (e.g., RS code alone) and with the unencoded data. Security of the printed data can be achieved through encryption. We have selected a probabilistic encryption scheme of messages to achieve an increased security against reverse engineering of the printed pattern. A new document signature extraction scheme based on fractal signal processing is described. Such a signature is then included with the document in the security pattern.
Genome-Wide Association Study in Bipolar Patients Stratified by Co-Morbidity (2011)

Conceptualizing bipolar disorder as a heterogeneous disorder with regard to co-morbid conditions might facilitate the identification of genetic risk alleles. Rare variants might contribute to the susceptibility to bipolar disorder.
A non-scan DFT method for controllers to achieve complete fault efficiency (2002)

This paper presents a non-scan design-for-testability method for controllers that are synthesized from FSMs (Finite State Machines). The proposed method can achieve complete fault efficiency: test patterns for a combinational circuit of a controller are applied to the controller using state transitions of the FSM. In the proposed method, at-speed test application can be performed and the test application time is shorter than previous methods. Moreover, experimental results show the area overhead is low.
Postoperative Infusional Continuous Regional Analgesia A Technique for Relief of Postoperative Pain Following Major Extremity Surgery (1991)

A new technique using postoperative infusional continuous regional analgesia (PICRA) for postoperative pain relief was investigated in 23 surgical patients treated by amputation (12 patients) or by limb-salvage resection operations (11 patients). Bupivacaine was delivered into peripheral nerve sheaths via catheters placed therein at the time of surgery. Only patients in whom the nerves were easily accessible were treated. Catheters were placed in the axillary sheath, the lumbosacral trunk, and the femoral nerve sheaths of patients treated with shoulder girdle and pelvic procedures (resections and amputations), and within the sciatic nerve sheath of those treated with lower extremity procedures. The anesthetic agent was delivered at controllable rates. Regional analgesia was obtained in the operative site with minimal motor or sensory decrease. To assess the efficacy of this technique, the results of this study group were compared with those of a matched group of 11 patients treated with similar surgical procedures but who received epidural morphine. Eleven of the 23 patients on PICRA required no supplemental narcotic agents. The mean level of the narcotic agents required by the remaining 13 PICRA patients was approximately one third of that required by the matched group of 11 patients receiving epidural morphine. Overall, the patients on PICRA had an 80% reduction of narcotic requirements when compared to the historical controls. The technique is reliable and can be performed by the surgeon, requiring about a ten-minute increase in operating time. It has potentially wide application in orthopedics in procedures in which the major nerves are easily accessible (e.g., pelvic fractures and revision hip surgery) and for patients with intractable pain of the extremities.

Distribution and Genetic Association of Putative Uropathogenic Virulence Factors Iron, iha, kpsMT, ompT and usp in Escherichia Coli Isolated From Urinary Tract Infections in Japan (2003)

Of the putative uropathogenic VFs examined iroN, iha, kpsMT, ompT and usp were frequently associated with urinary tract infection. Especially iroN and usp were most frequently associated with prostatitis. Some VFs were closely associated with a specific anatomical site of infection. Strong associations among several VFs might indicate not only well-known genetic linkages, but also unknown functional linkages among these VFs.

Circular RNAs: A novel type of non-coding RNA and their potential implications in antiviral immunity (2017)

Circular RNAs (circRNAs), a novel type of non-coding RNAs (ncRNAs), are ubiquitously expressed in eukaryotic cells during post-transcriptional processes. Unlike linear RNAs, circRNAs form covalent-closed continuous loops without 5' to 3' polarities and poly (A) tails. With advances in high-throughput sequencing technology, numerous circRNAs have been identified in plants, animals and humans. Notably, circRNAs display cell-type, tissue-type and developmental-stage specific expression patterns in eukaryotic transcriptome, which reveals their significant regulatory functions in gene expression. More importantly, circRNAs serve as microRNA (miRNA) sponges and crucial regulators of gene expression. Additionally, circRNAs modulate pre-mRNA alternative splicing and possess protein-coding capacity. CircRNAs exhibit altered expression under pathological conditions and are strongly associated with the development of various human diseases. Interestingly, circRNAs can also induce antiviral immune responses. A recent study found that the delivery of circRNAs generated <i>in vitro</i> activates RIG-I-mediated innate immune responses and provides protection against viral infection. The antiviral dsRNA-binding proteins, NF90/NF110, act as key regulators in circRNA biogenesis. NF90/NF110 are also functional in inhibiting viral replication through binding to viral mRNAs. In this review, we provide a comprehensive overview on the classification, biogenesis and functions of circRNAs. We also discuss the critical role of circRNAs in eliciting antiviral immunity, providing evidence for the potential implications of circRNAs in antiviral therapies.
Isolation, Characterization and Identification of Lactic Acid Bacteria from Fermented Sorghum Dough Used in Sudanese Kisra Preparation (2009)

Forty two isolates were selected from 15 samples of traditionally fermented household starter dough from Khartoum state and also from laboratory-prepared fermented dough. Isolates were phenotypically characterized by their ability to ferment 21 carbohydrates using API 20 CHL kits and additional biochemical tests. Lactic Acid Bacteria (LAB) and yeasts were enumerated. The pH and lactic acid content were also determined. The LAB counts in household fermented dough varied between 7.1 and 9.4 log cfu ml and yeast counts between 4.3 and 7.7 log cfu ml. The pH of household starter ranged from 3.7-4.5. The -1 initial numbers of LAB in laboratory-fermented sorghum dough were increased from 5.5-9.0 log cfu ml during fermentation. Yeasts increased from 4.3-7.7 log cfu ml at 19 h. The pH declined from 5.04 to around 3.7. Lactic acid increased from 0.03-1.25%. Lactic acid bacteria isolated from both traditionally and laboratory prepared fermented dough were Lactobacillus fermentum, Lactobacillus amylovorus and Lactobacillus brevis. The yeast isolates were identified as Saccharomyces cerevisiae.

Fully Differential CMOS LNA and Down-Conversion Mixer for 3-5 GHz MB-OFDM UWB Receivers (2007)

This paper presents a fully differential low noise amplifier (LNA) and I/Q down-conversion mixers for 3-5 GHz multiband OFDM (MB-OFDM) UWB receivers. The LNA adopts capacitive cross-coupling common-gate (CG) topology to achieve wideband input matching and low noise figure (NF). Tuning technique is used in the double-balanced Gilbert mixer to realize flat conversion gain in the whole 3-5 GHz UWB band. Degeneration inductors are used in the mixer to improve linearity. Designed in 0.18 mum CMOS technology, the LNA achieves a NF of 3.2-3.5 dB and a S11 of less than -13 dB. The LNA and mixer show a total conversion gain of 23.5~25.5 dB, a NF of less than 5dB, an input IP3 of-4.3 dBm and an input IP2 of 47 dBm, while consuming only 10.1 mA from a 1.8 V power supply.

CITRIC: A low-bandwidth wireless camera network platform (2008)

In this paper, we propose and demonstrate a novel wireless camera network system, called CITRIC. The core component of this system is a new hardware platform that integrates a camera, a frequency-scalable (up to 624 MHz) CPU, 16MB FLASH, and 64MB RAM onto a single device. The device then connects with a standard sensor network mote to form a camera mote. The design enables in-network processing of images to reduce communication requirements, which has traditionally been high in existing camera networks with centralized processing. We also propose a back-end client/server architecture to provide a user interface to the system and support further centralized processing for higher-level applications. Our camera mote enables a wider variety of distributed pattern recognition applications than traditional platforms because it provides more computing power and tighter integration of physical components while still consuming relatively little power. Furthermore, the mote easily integrates with existing low-bandwidth sensor networks because it can communicate over the IEEE 802.15.4 protocol with other sensor network platforms. We demonstrate our system on three applications: image compression, target tracking, and camera localization.
Expression and Purification of Functionally Active Hyaluronan-binding Domains from Human Cartilage Link Protein, Aggrecan and Versican (2004)

The chondroitin sulfate proteoglycan aggrecan forms link protein-stabilized complexes with hyaluronan (HA), via its N-terminal G1-domain, that provide cartilage with its load bearing properties. Similar aggregates (potentially containing new members of the link protein family), in which other chondroitin sulfate proteoglycans (i.e. versican, brevican, and neurocan) substitute for aggrecan, may contribute to the structural integrity of many other tissues including skin and brain. In this study, cartilage link protein (cLP) and the G1-domains of aggrecan (AG1) and versican (VG1) were expressed in Drosophila S2 cells. The recombinant human proteins were found to have properties similar to those described for the native molecules (e.g. cLP was able to form oligomers, and HA decasaccharides were the minimum size that could compete effectively for their binding to polymeric HA). Gel filtration and protein cross-linking/matrix-assisted laser desorption ionization time-of-flight peptide fingerprinting showed that cLP and AG1 interact in the absence or presence of HA. Conversely, cLP and VG1 did not bind directly to each other in solution yet formed ternary complexes with HA24. N-linked glycosylation of AG1 and VG1 was demonstrated to be unnecessary for either HA binding or the formation of ternary complexes. Surprisingly, the length of HA required to accommodate two G1-domains was found to be significantly larger for aggrecan than versican, which may reflect differences in the conformation of HA stabilized on binding these proteins.
