An efficient hardware based MAC design in digital filters with complex numbers (2014)

This paper proposes a novel fixed point complex number multiply accumulate circuit, which is used in real time digital signal processing applications. The proposed architecture consists of multiplier-cum-accumulator which can be used as multiplier as well as MAC. Here the previous MAC result is added as one of the partial products of the current multiplication. So the depth of the multiplier-cum-accumulator unit remains same as O(log <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> n) in case of Wallace tree multiplier based multiplier-cum-accumulator and O(n) in case of Braun multiplier based multiplier-cum-accumulator. And hence the separate accumulator with depth O(log <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> n) can be avoided. The performance results are showing that proposed architecture gives the better performance compared with conventional fixed point complex number MAC. The proposed architecture achieves an improvement factor of 32.4% in Wallace tree and 19.1% in Braun multiplier based fixed point complex number MAC with out pipeline using 45 nm technology library. The same architecture achieves an improvement factor of 14.6% in Wallace tree and 12.2% in Braun multiplier based fixed point complex number MAC with pipeline.
Identifying Equivalent SDN Forwarding Behaviour (2019)

Software-Defined Networking (SDN) enables network operators the flexibility to program their own forwarding rules, providing more than one way to achieve the same behaviour. Verifying equivalence between rulesets is a fundamental analysis and verification building block for SDN as it can be used to: (1) confirm a ruleset optimised for power efficiency or table occupancy remains equivalent, (2) verify a ruleset modified for new hardware, (3) regression test an SDN application to detect bugs early.

Executing MPI programs on virtual machines in an Internet sharing system (2006)

Internet sharing systems aim at federating and utilizing distributed computing resources across the Internet. This paper presents a user-level virtual machine (VM) approach to MPI program execution in an Internet sharing framework. In this approach, the resource consumer has its own operating system running on top of, and isolated from, the operating system of the resource provider. We propose an efficient socket virtualization technique to optimize VM network performance. Socket virtualization achieves the same network bandwidth as the physical network. In our LAN environment, it reduces the latency overhead from 172% (using existing TUN/TAP technique) to 35.6%. Performance results on MPI benchmarks show that our virtualization technique incurs small overhead compared with the physical host platform, while gaining in return a higher degree of guest isolation and customization. We also describe the key mechanisms that allow the employment of VMs in an existing Internet sharing system.
Custom power: Optimizing distribution services (1996)

Power disturbances that once would barely have been noticed may now produce costly malfunctions in critical customer equipment. Fortunately, a new generation of power electronic controllers is becoming available for use on distribution systems, which will enable utilities to provide premium-quality electricity to customers with sensitive loads. The first of these controllers, called Custom Power devices, are now entering utility service, providing a cost effective alternative to the power-conditioning equipment previously installed on customers` premises. Eventually, the integration of Custom Power controllers with distribution automation equipment will help create distribution systems that are optimized from both the utility`s and the customer`s point of view.
Comparison of cavity geometries for a microphone array in an open-jet wind-tunnel experiment (2020)

This paper analyses the influence of microphone cavity geometry on beamforming measurements with a turbulent boundary layer present on the microphone array. A 16- microphone array was tested in the anechoic open-jet wind tunnel of the Delft University of Technology. The array was placed on a flat plate mounted flush with the exit nozzle of the wind tunnel. Microphones were installed in three different cavity geometries along with a flush mounted microphone array which was used as a baseline for comparison. The geometries include a chamfered-cylindrical hard-plastic cavity, a chamfered-cylindrical cavity made of melamine foam, and a chamfered-cylindrical cavity with star-shaped protrusions, also made of melamine. The recessed cavities were covered with a 0.026 mm gauge steelwire cloth. A speaker emitting white noise outside of the flow was employed as a sound source. Different flow velocities at the same sound power level for the speaker (and hence different signal-to-noise ratios) were studied. The results obtained with the three cavity geometries are compared with the flush-mounted case in terms of the quality of the acoustic source maps (location and strength of the sound source). The signal-to-noise ratio of the beamforming measurements increased by as much as 30 dB by placing microphones within a conical cavity with melamine foam walls when compared to the flush mounted case.
Functional recovery following neurorrhaphy of the rat sciatic nerve by epineurial repair compared with tubulization (1997)

Recovery of motor function is often poor following transection injuries to peripheral nerves. The purpose of this study was to measure and compare functional recovery of the sciatic nerve in the rat following transection and neurorrhaphy with the use of a nerve guide tube and with traditional end-to-end epineurial repair. Muscle recovery was also evaluated following a crush injury, a model of an axonotmetic lesion. Recovery was assessed at 8, 16, and 32 weeks after injury by measuring the isometric contractile properties of the soleus muscle and at 8 and 16 weeks by measuring the conduction properties of the sciatic nerve. The mean conduction velocity of the sciatic nerve in the crush group and both transection groups was significantly slower than that of controls at both 8 and 16 weeks. Following a transection injury, the soleus became a significantly faster muscle as measured by time to peak twitch tension. By 32 weeks, the maximum isometric tension of the soleus muscle recovered to 90% that of the control group following a crush injury and to less than 70% following a transection injury and repair. Recovery was better in the epineurial repair group than in the tube repair group at 8 weeks, but no difference was found between the groups at 16 or 32 weeks. These results demonstrate that nerve guide tubes are a potential alternative to epineurial repair. The poor motor recovery following repair of transection injuries may be related to poor specificity of reinnervation.

Changes of tissue fluid hyaluronan (hyaluronic acid) in peripheral lymphedema. (1998)

Hyaluronan (hyaluronic acid or HA) is an important component of the extracellular matrix which is synthesized in the tissue, transported in lymph and catabolized mainly in lymph nodes and the liver. In 39 patients with chronic peripheral lymphedema, the HA content in lymphedematous interstitial fluid was measured using radioimmunoassay. For comparison, the concentration of HA in serum and normal tissue fluid were also determined. These samples were also tested for protein concentration. The results showed that the HA concentration in interstitial fluid of a lymphedema limb was 22 x 10(3) +/- 10(3) (aspiration) and 30 x 10(3) +/- 4 x 10(3) (wick) ng/ml which were significantly higher than that in interstitial fluid, serum and lymph of normal limbs (control) and interstitial fluid of limbs with venous edema (p < 0.001). The protein concentration in these fluids did not show significant differences between lymphedema and those with normal limbs. The findings suggest that HA stagnates in the limb with impaired lymph drainage which may exert a deleterious effect on the interstitium.
Glass transition and melting point of poly(vinyl chloride) (1962)

Abstract Both the glass transition temperature and the melting point of poly(vinyl chloride have been found to increase as the temperature at which the ample is polymerized is decreased). The glass transition temperature changes from about 70°C. for polymer prepared at 125°C. to about 100°C. for polymer prepared at −80°C. It is believed the increase in percentage of syndiotactic structure which results from decreasing the polymerization temperature is responsible for the change in glass transition temperature. The effect of polymerization temperature on melting point is even more striking. The melting point changes from approximately 160 to above 300°C. on lowering the polymerization temperature from 125 to −80°C. X‐ray diffraction studies show that polymers prepared at low temperature form crystals which have a substantial increase in perfection along the chain axis. It seems probable that this increase in crystalline perfection along the chain axis is responsible for the very marked increase in melting point.
A controlled and blinded study of immunoreactant deposition at the dermal-epidermal junction of patients with primary fibrositis syndrome. (1986)

The prevalence of immunoreactant deposition at the dermal-epidermal junction (DEJ) in clinically normal, sun exposed skin was assessed by direct immunofluorescence (IF) in 36 patients with primary fibrositis syndrome (PFS) and 12 clinically healthy control subjects. A granular or homogeneous deposition of IgG was seen at the DEJ in 52.8% (19/36) of patients with PFS and in 16.7% (2/12) of controls. The difference in IgG deposition between patients with PFS and controls was statistically significant (p = 0.030). Patients with PFS and controls did not demonstrate significant IF staining for IgA, IgM, or C3. Albumin deposition at the DEJ appeared to parallel IgG deposition in patients with PFS and control subjects who were positive for this immunoglobulin. No relationship was noted between IgG deposition and demographic or clinical characteristics of these patients' disease. These data suggest that IgG and albumin deposition at the DEJ is frequent in PFS and that further study of this skin phenomenon is warranted.
Asthma Disease Management: A Worksite-Based Asthma Education Program (2001)

Asthma accounts for an estimated 3 million workdays lost each year in the United States in addition to reduced worker productivity. Although asthma disease management programs are relatively common in managed care organizations, they have generally not been offered at the workplace. Seventy-six employees participated in a five-session worksite-based asthma education program. A total of 47 of 76 (61.8%) employees completed baseline and 12-month follow-up Asthma Therapy Assessment Questionnaires (ATAQ). The ATAQ includes measurement of poor asthma control, behavior/attitude barriers, knowledge barriers, patient/provider communication barriers, and efficiency. Significant improvement was noted in measures of asthma control (p < 0.05), communication (p < 0.005), knowledge (p < 0.001), and the total ATAQ Index declined from 5.53 to 4.04 (p < 0.001). Employee satisfaction results for the program were exceptionally high. A worksite-based asthma education program should reduce medical care costs, worker absenteeism, and improve worker productivity. The worksite can be a very effective location for disease education programs.
Ethyl acetate extracts of alfalfa (Medicago sativa L.) sprouts inhibit lipopolysaccharide-induced inflammation in vitro and in vivo (2009)

This study aimed to investigate if food components that exert anti-inflammatory effects may be used for inflammatory disorders by examining alfalfa sprout ethyl acetate extract (ASEA). The cytokine profile and life span of BALB/c mice with acute inflammation after intra-peritoneal (ip) injection of 15 mg/kg BW lipopolysaccharide (LPS) were determined. The results showed that the life span of LPS-induced inflammatory mice were negatively correlated with serum levels of TNF-alpha, IL-6, and IL-1beta at 9 hr after LPS-injection, which indicated that suppressing these cytokines in the late phase of inflammation may be beneficial for survival. The in vitro experiment then showed that ASEA significantly reduced IL-6 and IL-1beta production and the NF-kappaB trans-activation activity of mitogen-stimulated RAW264.7 cells. To further evaluate the anti-inflammatory effects of ASEA in vivo, BALB/c mice were tube-fed with 25 mg ASEA/kg BW/day in 50 microl sunflower oil, while the control and PDTC (pyrrolidine dithiocarbamate, an anti-inflammatory agent) groups were tube-fed with 50 microl sunflower oil/day only. After one week of tube-feeding, the PDTC group was injected with 50 mg/kg BW PDTC and one hour later, all of the mice were injected with 15 mg/kg BW LPS. The results showed that the ASEA and PDTC groups had significantly lower serum TNF-alpha, IL-6, and IL-1beta levels at 9 hr after LPS challenge, and significantly higher survival rates than the control group. This study suggests that ASEA supplementation can suppress the production of pro-inflammatory cytokines and alleviate acute inflammatory hazards.
Natural history of chronic hepatitis C. (1999)

Chronicization rate of hepatitis C virus infection is very high. Hepatitis C virus infection can result in a wide prognostic spectrum of liver disease, ranging from cirrhosis and hepatocellular carcinoma to subclinical, nonprogressive disease. Cofactors such as alcohol excess are important in determining the outcome of hepatitis C virus-related chronic liver disease.
The <sup>40</sup> Ar/ <sup>39</sup> Ar age spectrum of a rock from Gerrans Bay, Cornwall (1984)

The results of the 40 Ar/ 39 Ar step heating study of a folded and cleaved metasiltstone from Malmanare Point, Gerrans Bay, S Cornwall are presented. The rock comes from the mélange of the Roseland area, NE of the Lizard. The age spectrum obtained has two distinct sectors: (i) an older age component giving apparent ages of 521–490 Ma and (ii) a younger component with an apparent age of 424–410 Ma. The petrography suggests that the former is derived from the more resistant parts of large detrital muscovite flakes, while the latter comes from smaller metamorphic micas aligned along the prominent cleavage and also, in part, from original detrital grains partially or totally overprinted during the metamorphic event. The sediment was probably mid- to late-Ordovician in age. The source rocks appear to have been very largely of late Cambrian/early Arenig age. Folding, cleavage and low-grade regional metamorphism occurred as a result of late Caledonian orogenesis between 424–410 Ma. There is no evidence of any Variscan overprint on the age spectrum. Very minor, low energy argon losses appear to have taken place in mid-Mesozoic times (possibly related to regional mineralization) but, apart from this, the absence of any major overprint younger than 410 Ma indicates that since the end of the Silurian the rock has suffered only high-level, cold, non-penetrative deformation.
La formation à l'employabilité (2000)

Résumé L'article porte sur la formation à l'employabilité. Après avoir clarifié le concept d'employabilité, décrit le contexte politique et les contenus de formation, et présenté l'évaluation qu'on a faite des programmes de formation à l'employabilité, les autrices défendent l'idée que, en favorisant un consensus autour de la pertinence de pratiques où chacun trouve son compte, le discours sur l'employabilité a eu pour effet de mobiliser un nombre important d'acteurs et ce, malgré le caractère inopérant de la plupart des interventions pour les sans-emploi. Les autrices ont choisi le concept habermassien de l'agir communicationnel pour discuter du pouvoir du langage sur les actions et repérer quelques enjeux liés à la formation à l'employabilité. The article focuses on employability. A clarification of the concept is followed by a description of the policies related to training for employability, their content, and some evaluative data. The authors defend the idea that, in favoring a consensus on the relevance of practices wherein everyone finds some profit, the discourse on employability has had the effect of mobilizing an important number of actors despite the ineffectiveness of most initiatives targeted at the unemployed. They ground their analysis on Habermas's theory of communicative action, discuss the influence of language on comprehension and enactment, and point to what is at stake in the area of employability.

Administrative Committee Meeting (1958)

The Administrative Committee of the PGNS met on October 31, 1957, in the offices of the Associated Universities, Room 1750, Coliseum Tower. The Chairman, J.N. Grace, presided. Considerable discussion took place on methods of assuring high quality technical papers for the various PGNS activities. H.D. LeVine was appointed chairman of an ad hoc planning committee to 1) explore means of solving the long-term problem of assuring the quality of papers for both the meetings and TRANSACTIONS, and 2) explore themes and topics for the Fifth Annual Meeting to ensure a cohesive, wellintegrated program. G.A. Morton presented a report on plans for the Scintillation Counter Symposium of which the IRE is a joint sponsor. The question of publication of Symposium papers in the TRANSACTIONS is to be discussed after the Symposium has been held and the funds available to assist publication are known.
Oxidative DNA damage and defence gene expression in the mouse lung after short-term exposure to diesel exhaust particles by inhalation (2003)

Exposure to diesel exhaust particles (DEP) is suspected to contribute to lung cancer and cardiopulmonary diseases. In recent years generation of reactive oxygen species capable of inducing cellular oxidative stress has been in focus as one of the underlying mechanisms behind the genotoxic effects of particles. However, the role of the antioxidative defence system still needs to be clarified, especially in relation to low-dose DEP exposures. The aim of this study was to characterize the effects of short-term exposure to DEP in terms of DNA damage and expression of key response genes towards oxidative stress in lungs of mice. Mice were exposed by inhalation to 20 or 80 mg/m3 DEP inhaled as either a single dose, or four lower doses (5 and 20 mg/m3) inhaled on four consecutive days. Our results indicate that HO-1 mRNA expression in lung tissue was up-regulated after both types of DEP exposures, whereas OGG1 expression was only up-regulated after repeated exposures. The level of oxidative DNA damage in terms of 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) was increased in the lung tissue after a single exposure, whereas increased levels of DNA strand breaks was observed in bronchoalveolar lavage cells after repeated DEP exposures. The levels of 8-oxodG and OGG1 mRNA in lung tissue were mirror images. This suggests that after repeated exposures, up-regulation of DNA repair counteracts an increased rate of 8-oxodG formation leaving the steady state level of 8-oxodG in DNA unchanged. In conclusion, this study indicates that a single high dose of DEP generates 8-oxodG in lung tissue, whereas the same dose inhaled as four low-exposures may up-regulate the antioxidative defence system and protect against generation of 8-oxodG.
