Acoustic wave propagation in buried iron water pipes (2003)

A study of the possible axisymmetric modes that propagate at low frequencies in buried, water‐filled iron pipes is presented. It is well known that for a vacuum‐pipe‐vacuum system the sole non‐torsional axisymmetric mode that exists at low frequencies is the fundamental L(0,1) mode. When a pipe is filled with water and still surrounded by a vacuum it is also known that another mode then appears, which at low frequencies is characterized by predominantly axial water‐borne displacements. In addition to these modes, this paper explores two other, less‐well‐known axisymmetric modes whose existence depends on the acoustic properties of the outer medium that surrounds a pipe. The predicted characteristics of these modes are presented; the likelihood of them propagating over any significant distance in a buried water pipe is discussed, followed by an experimental validation using measurements on water mains in urban areas of the UK.

Air interface protocols for a national mobile data network (1993)

In 1990 the UK Government granted licences for national mobile data networks. This provided the opportunity for companies to implement mobile radio systems utilising hardware and protocols designed specifically for data-only transmission. The author provides an overview of the air interface protocols of one such network based on the Mobitex mobile data system. The network is a hierarchical structure. Sufficient intelligence is built into each node so that any message need only travel up the hierarchy as high as a common node. A radio modem (or mobile) communicates to the network using a UHF radio link to a base station. Data transmission is at 8 kbit/s using GMSK (gaussian minimum shift keying). The protocol operating on this link is called ROSI (radio signalling protocol) and this supports the transmission of small packets of data called MPAK.
Design of an automotive safety system using Controller Area Network (2015)

Most of the people are using vehicles which have become the most important part in our life for comfort transportation. In existing system the main snags are cost as well as the first one are glaring effect accidents due to opposite vehicle headlight illumination at night time driving. Second one is the short circuit fault in automotive wiring. Third one is to perceive the gas leakage fire accidents. And the fourth one is faults due to temperature of automotive engine location. The proposed system has two modules Master and Slave, they are communicating through Controller Area Network (CAN) protocol. The Master module has gas leakage detection with protection and temperature monitoring function. The Slave module has Automatic Front Headlight Adjustment system (AFHAS) and short circuit fault line indication function. The hardware has been developed in SMT (Surface Mount Technology) with SMD (Surface Mount Device) components and the hardware uses double layer PCB (Printed Circuit Board) design to optimize the space requirement and power consumption. The proposed system will be in cost effective safety system, reliability, and hardware will be small in size.

Fitness Effects on the Cognitive Function of Older Adults (2003)

A meta-analytic study was conducted to examine the hypothesis that aerobic fitness training enhances the cognitive vitality of healthy but sedentary older adults. Eighteen intervention studies published between 1966 and 2001 were entered into the analysis. Several theoretically and practically important results were obtained. Most important fitness training was found to have robust but selective benefits for cognition, with the largest fitness-induced benefits occurring for executive-control processes. The magnitude of fitness effects on cognition was also moderated by a number of programmatic and methodological factors, including the length of the fitness-training intervention, the type of the intervention, the duration of training sessions, and the gender of the study participants. The results are discussed in terms of recent neuroscientific and psychological data that indicate cognitive and neural plasticity is maintained throughout the life span.
Visual Simulation of Atmospheric Haze (1987)

Abstract For applications such as daylight visual pilot training simulators, the correct representation of aerial haze, mist and fog is of major importance in providing accurate depth cues and training in poor visibility conditions. We present a straightforward derivation of a formula to express this and then show various pictorial examples to illustrate its effectiveness.
Prediction of Tricyclic Antidepressant Response (1976)

This article reviews all the prospective, double-blind controlled studies that have evaluated the prediction of response to imipramine hydrochloride and amitriptyline hydrochloride in depressed patients. Despite widely divergent methodologies, an attempt is made to extract clinically useful conclusions from these data. Critiques of each study and the criteria used in their evaluation are presented, with suggestions for future research included. The predictors of positive response to imipramine and amitriptyline are as follows: upper socioeconomic class, insidious onset, anorexia, weight loss, middle and late insomnia, and psychomotor disturbance. The predictors of poor response are the following: neurotic, hypochondriacal, and hysterical traits, multiple prior episodes, and delusions. Pretreatment urinary 3-methoxy-4-hydroxyphenylglycol (MHPG) levels may some day be useful in predicting to which of these two tricyclic antidepressants a patient will respond.

tRNA <sup>His</sup> maturation: An essential yeast protein catalyzes addition of a guanine nucleotide to the 5′ end of tRNA <sup>His</sup> (2003)

All tRNAHis molecules are unusual in having an extra 5' GMP residue (G(-1)) that, in eukaryotes, is added after transcription and RNase P cleavage. Incorporation of this G(-1) residue is a rare example of nucleotide addition occurring at an RNA 5' end in a normal phosphodiester linkage. We show here that the essential Saccharomyces cerevisiae ORF YGR024c (THG1) is responsible for this guanylyltransferase reaction. Thg1p was identified by survey of a genomic collection of yeast GST-ORF fusion proteins for addition of [alpha-32P]GTP to tRNAHis. End analysis confirms the presence of G(-1). Thg1p is required for tRNAHis guanylylation in vivo, because cells depleted of Thg1p lack G(-1) in their tRNAHis. His6-Thg1p purified from Escherichia coli catalyzes the guanylyltransferase step of G(-1) addition using a ppp-tRNAHis substrate, and appears to catalyze the activation step using p-tRNAHis and ATP. Thg1p is highlye conserved in eukaryotes, where G(-1) addition is necessary, and is not found in eubacteria, where G(-1) is genome-encoded. Thus, Thg1p is the first member of a new family of enzymes that can catalyze phosphodiester bond formation at the 5' end of RNAs, formally in a 3'-5' direction. Surprisingly, despite its varied activities, Thg1p contains no recognizable catalytic or functional domains.

Perfluorooctanesulfonate and other fluorochemicals in the serum of American Red Cross adult blood donors. (2003)

Perfluorooctanesulfonyl fluoride-based products have included surfactants, paper and packaging treatments, and surface protectants (e.g., for carpet, upholstery, textile). Depending on the specific functional derivatization or degree of polymerization, such products may degrade or metabolize, to an undetermined degree, to perfluorooctanesulfonate (PFOS), a stable and persistent end product that has the potential to bioaccumulate. In this investigation, a total of 645 adult donor serum samples from six American Red Cross blood collection centers were analyzed for PFOS and six other fluorochemicals using HPLC-electrospray tandem mass spectrometry. PFOS concentrations ranged from the lower limit of quantitation of 4.1 ppb to 1656.0 ppb with a geometric mean of 34.9 ppb [95% confidence interval (CI), 33.3-36.5]. The geometric mean was higher among males (37.8 ppb; 95% CI, 35.5-40.3) than among females (31.3 ppb; 95% CI, 30.0-34.3). No substantial difference was observed with age. The estimate of the 95% tolerance limit of PFOS was 88.5 ppb (upper limit of 95% CI, 100.0 ppb). The measures of central tendency for the other fluorochemicals (N-ethyl perfluorooctanesulfonamidoacetate, N-methyl perfluorooctanesulfonamidoacetate, perfluorooctanesulfonamidoacetate, perfluorooctanesulfonamide, perfluorooctanoate, and perfluorohexanesulfonate) were approximately an order of magnitude lower than PFOS. Because serum PFOS concentrations correlate with cumulative human exposure, this information can be useful for risk characterization.
<i>In Vivo</i>Validation of a Hybrid Tracking System for Navigation of an Ultrathin Bronchoscope Within Peripheral Airways (2009)

Transbronchial biopsy of peripheral lung nodules is hindered by the inability to access lesions endoluminally due to the large diameter of conventional bronchoscopes. An ultrathin scanning fiber bronchoscope has recently been developed to advance image-guided biopsy several branching generations deeper into the peripheral airways. However, navigating a potentially complex 3-D path to the region of interest presents a challenge to the bronchoscopist. An accompanying guidance system has also been developed to track the bronchoscope through the airways, and display its position and intended path on a virtual display. Intraoperative localization of the bronchoscope was achieved by combining electromagnetic tracking (EMT) and image-based tracking (IBT). An error-state Kalman filter was used to model the disagreement between the two tracking sources. The positional tracking error was reduced from 14.22 and 14.92 mm by independent EMT and IBT, respectively, to 6.74 mm using the hybrid approach. Hybrid tracking of the scope orientation and respiratory motion compensation further improved tracking accuracy and stability, resulting in an average tracking error of 3.33 mm and 10.01 degrees.
Application of the <u>W</u>COBRA/TRAC Best Estimate Methodology to the AP600 Large-Break LOCA Analysis (1997)

Abstract The AP600 is a simplified advanced pressurized water reactor (PWR) design incorporating passive safety systems that perform the same function as the active emergency core cooling systems (ECCSs) on the current reactors. In order to verify the effectiveness of the AP600 design features for mitigation of a postulated large-break loss-of-coolant accident (LOCA), the recently USNRC-approved best-estimate LOCA methodology (BELOCA) was applied to perform the AP600 standard safety analysis report large-break LOCA analysis. The applicability of the WCOBRA/TRAC code to model the AP600 unique features was validated against CCTF and UFTE downcomer injection tests, the blowdown and reflood cooling heat transfer uncertainties were re-assessed for the AP600 large-break LOCA conditions, and a conservative minimum film boiling temperature was applied as a bounded parameter for blowdown cooling. The BELOCA methodology was simplified to quantify the code uncertainties due to local and global models as well as the statistical approximation methods, with the other uncertainties being bounded by limiting assumptions on the initial and boundary conditions. The final 95 percentile peak cladding temperature (PCT95%) was 1186 K, which meets the 10CFR50.46 criteria with a considerable margin. It is therefore concluded that the AP600 design is effective in mitigation of a postulated large-break LOCA.

Cu filling of 10 nm trenches by high-magnetic-field magnetron sputtering (2014)

Ru and Cu sputterings were performed with two different high-vacuum sputtering systems. The Ru sputtering was performed by high-vacuum sputtering. On the other hand, the Cu sputtering was performed by high-magnetic-field sputtering. High-magnetic-field sputtering, which entails a Cu deposition rate of 80 nm/min (target–substrate distance: 200 mm) at a sputtering pressure of 7 × 10−2 Pa, is used for the Cu filling of 10-nm-wide Ru-lined trenches with an aspect ratio of 6.5. The complete Cu filling of trenches is accomplished within 1 min of sputtering time using a 1 at. % N2–Ar sputtering gas. The reason for the complete Cu filling is considered in terms of the capillary theory, focusing on the wettability of Cu on Ru. The improvement in Cu wettability with the use of a N2 additive is also evaluated in terms of the contact angle for Cu on Ru and surface shape.
Dehydroepiandrosterone, Its Sulfate and Cognitive Functions (2016)

Two thousand fifty five references about cognition and hormones were found; 772 duplicated references were excluded, resulting in 1.283 references to be evaluated. According to exclusion and inclusion criteria, 25 references were selected. A positive correlation between DHEA-S blood levels and global cognition was found in women and men. Other positive correlations between DHEA-S and working memory, attention and verbal fluency were found only in women. The DHEA effect on cognition is limited to one study conducted among young men with high-doses.
Association of the Dysbindin Gene With Bipolar Affective Disorder (2006)

Findings suggest that the human dysbindin gene may play a role in the susceptibility to bipolar affective disorder, which underscores a potentially important area of etiological overlap with schizophrenia. The existence of shared genetic risk factors will, in time, lead to changes in the current nosology of major psychoses.
Molecular analysis of a variant 18;22 translocation in a case of lymphocytic lymphoma (1993)

We previously reported a 5' rearrangement of the BCL2 locus in a t(18;22) variant translocation found in a lymphocytic lymphoma. Primary structure analysis of both rearranged chromosomes confirmed the localization of the breakpoint in the so-called vcr region (for variant cluster region) that encompasses Z-DNA stretches 5' of the BCL2 locus, and in between J lambda 1 and C lambda 1 segments on the IGL locus. A 1,027 nucleotide segment from chromosome 22 was repeated on both derivative chromosomes 18q+ and 22q-. This segment contained an octanucleotide that was also present in the normal chromosome 18 close to the breakpoint. As a consequence of the translocation, a normal-sized BCL2 transcript was overexpressed in tumor cells.

HSV and Glycoprotein J Inhibit Caspase Activation and Apoptosis Induced by Granzyme B or Fas (2001)

HSV-1 inhibits apoptosis of infected cells, presumably to ensure that the infected cell survives long enough to allow completion of viral replication. Because cytotoxic lymphocytes kill their targets via the induction of apoptosis, protection from apoptosis could constitute a mechanism of immune evasion for HSV. Several HSV genes are involved in the inhibition of apoptosis, including Us5, which encodes glycoprotein J (gJ). Viruses deleted for Us5 showed defects in inhibition of caspase activation after Fas ligation or UV irradiation. Transfected cells expressing the Us5 gene product gJ were protected from Fas- or UV-induced apoptosis, as measured by morphology, caspase activation, membrane permeability changes, or mitochondrial transmembrane potential. In contrast, caspase 3 activation in mitochondria-free cell lysates by granzyme (gr)B was inhibited equivalently by Us5 deletion and rescue viruses, suggesting that gJ is not required for HSV to inhibition this process. However, mitochondria-free lysates from transfected cells expressing Us5/gJ were protected from grB-induced caspase activation, suggesting that Us5/gJ is sufficient to inhibit this process. Transfected cells expressing Us5/gJ were also protected from death induced by incubation with purified grB and perforin. These findings suggest that HSV has a comprehensive set of immune evasion functions that antagonize both Fas ligand- and grB-mediated pathways of CTL-induced apoptosis. The understanding of HSV effects on killing by CTL effector mechanisms may shed light on the incomplete control of HSV infections by the immune system and may allow more rational approaches to the development of immune modulatory treatments for HSV infection.
New tree structure with conditional height differencefor wavelet transform image coding (1995)

The proposed tree structure for image coding exploits the similarity between hierarchical bands of the wavelet transform. Each node has a height attribute and the tree structure is represented as a conditional height difference to remove the statistical dependency between hierarchical nodes. For the 512 × 512 Lena image, the result shows above 40 dB at 1 bit/pixel.
An Effective Privacy-Preserving Algorithm Based on Logistic Map and Rubik’s Cube Transformation (2014)

Security and privacy issues present a strong barrier for users to adapt to cloud storage systems. In this paper, a new algorithm for data splitting called EPPA is presented to strengthen the confidentiality of data by two-phase process. In EPPA, data object is organized to be several Rubik’s cubes executed for several rounds transformation at the first phase. In every round, chaotic logistic maps generate pseudorandom sequences to cover the plaintext by executing Exclusive-OR operation to form the cipher. Then logistic map is used to create rotation policies to scramble data information based on Rubik’s cube transformation. At the second phase, all cubes are unfolded and combined together as a cross-shaped cube, which will be partitioned into a few data fragments to guarantee that every fragment does not contain continuous bytes. These fragments are stored on randomly chosen servers within cloud environment. Analyses and experiments show that this approach is efficient and useable for the confidentiality of user data in cloud storage system.
Particulate Emissions from Current Model Vehicles Using Gasoline with Methylcyclopentadienyl Manganese Tricarbonyl (1991)

<div class="htmlview paragraph">Particulate and manganese mass emissions have been measured as a function of mileage for four Escort and four Explorer vehicles using both methylcyclopentadienyl manganese tricarbonyl (MMT) gasoline at 1/32 g Mn/gal and MMT-free gasoline. The vehicles were driven on public roads at an average speed of 54 mph to accumulate mileage, and the MMT was used in half of the fleet starting at 5,000 miles. This is an interim report describing the particulate and manganese emissions at 5,000, 20,000 and 55,000 miles. These vehicles are scheduled to continue mileage accumulation to 105,000 miles with emission testing at 85,000 and 105,000 miles. Of the total manganese used in the fuel, between 6% and 45% was emitted as airborne particulate matter, and the remainder was probably stored in the engine, catalyst and the exhaust system. The percentage of the manganese that was emitted increased with mileage accumulation. The EPA reports that manganese emissions of this magnitude may represent a health hazard. Also about 8% of the manganese used in the fuel was found in the engine oil. The manganese that is stored in the engine, catalyst and the exhaust system will be analyzed when the vehicles reach 105,000 miles. The total particulate emissions were between 0 and 5 mg/mi increasing with mileage accumulation and with MMT usage. The regulated emissions are approximately 0.3 g HC/mi, 3 g CO/mi and 0.4 g NO<sub>x</sub>/mi. The regulated and non-regulated gaseous emissions will be described in companion reports.</div>
