Stochastic Modeling of Stratospheric Temperature (2022)

Abstract This study suggests a stochastic model for time series of daily zonal (circumpolar) mean stratospheric temperature at a given pressure level. It can be seen as an extension of previous studies which have developed stochastic models for surface temperatures. The proposed model is a combination of a deterministic seasonality function and a Lévy-driven multidimensional Ornstein–Uhlenbeck process, which is a mean-reverting stochastic process. More specifically, the deseasonalized temperature model is an order 4 continuous-time autoregressive model, meaning that the stratospheric temperature is modeled to be directly dependent on the temperature over four preceding days, while the model’s longer-range memory stems from its recursive nature. This study is based on temperature data from the European Centre for Medium-Range Weather Forecasts ERA-Interim reanalysis model product. The residuals of the autoregressive model are well represented by normal inverse Gaussian-distributed random variables scaled with a time-dependent volatility function. A monthly variability in speed of mean reversion of stratospheric temperature is found, hence suggesting a generalization of the fourth-order continuous-time autoregressive model. A stochastic stratospheric temperature model, as proposed in this paper, can be used in geophysical analyses to improve the understanding of stratospheric dynamics. In particular, such characterizations of stratospheric temperature may be a step towards greater insight in modeling and prediction of large-scale middle atmospheric events, such as sudden stratospheric warming. Through stratosphere–troposphere coupling, the stratosphere is hence a source of extended tropospheric predictability at weekly to monthly timescales, which is of great importance in several societal and industry sectors.
An integrated satellite-HAP-terrestrial system architecture: resources allocation and traffic management issues (2005)

This paper explains the potential role of an integrated satellite-HAP (high altitude platform)-terrestrial system. A simple and suitable architecture is presented. The proposed architecture consists of three layers: the terrestrial layer, HAP layer and GEO layer. The terrestrial layer's terminals, within the same HAP coverage area, have to use a HAP transponder and HAP master control station (HMCS) to send and receive data amongst themselves. Moreover the HAP gateway stations (HGTW) guarantees communications among users belonging to different HAP coverage areas using the GEO satellite links. Since high quality multimedia application support is a key objective for upcoming communication systems, this paper investigates the issues related to this topic. In order to guarantee an adequate quality of service to these kinds of service requires an efficient resources allocation and traffic management algorithm to be implemented inside the HMCS and HGTW stations.

Design of a Small Pilot Plant for the Study of Supercritical Processes for the Production of Biodiesel from Waste Chicken Fat (2013)

A process to produce biodiesel from chicken fat and other oils using supercritical methanol at 200 bars and 400 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">o</sup> C with residence times 6-9 minutes was designed using CHEMCAD. Major process units for the process (pumps, heat exchangers, reactor, and distillation columns) were sized and the heating and cooling requirements for several process variations were evaluated. Methanol to oil ratios or 6/1, 9/1 and 9/1 with recycle were considered. The results were then used to estimate the cost of a small pilot plant to produce 2 gal/day of biodiesel fuel.
Development of New Nonlinear Optical Crystals (1988)

First, starting from the anionic group theory of nonlinear optical (NLO) effect in the crystals, it is found that NLO and some linear optical properties, e.g. the birefringence and absorption edge, in the boron-oxygen compounds are mainly determined by boron-oxygen groups. On this basis, various types of boron-oxygen compounds are classified according to the theory and systematic calculations have been carried out on NLO susceptibilies of various boron-oxygen groups in the compounds. Then several structural criterias have been suggested; particularly the requirement of the structure of boron-oxygen groups to produce large SHG coefficients and suitable linear optical properties. It is these theoretical and experimental knowledge that leads Chen’s group to discover several new NLO crystals from the boron-oxygen compounds, including β-BaB2O4(BBO) and LiB3O5 (LBO).

Feedback control of highway congestion by a fair on-ramp metering (2002)

The problem considered in this paper is motivated by the fact that the existing feedback control approaches to highway congestion prevention may result in an unfair capacity allocation whereby one ramp may capture most of the highway capacity, depending on its relative location in the network. To avoid this problem, a new control architecture is proposed. In the framework of this architecture, each segment of the highway is equipped with a congestion controller which, according to a decentralized control law and local measurements, calculates the traffic admission rate beneficial from this segment's point of view. These rates are transmitted to the on-ramps which, according to a control protocol, select the traffic admission rate beneficial from the network's point of view. Thus, the system under consideration is represented by a set of decentralized controllers interacting through the network. It is shown that: (1) the steady states of the system satisfy the so-called max-min fairness property; (2) there exists a set of controller gains that ensure asymptotic stability of these steady states; (3) an adaptive method for the selection of these gains is proposed. Finally results of a numerical investigation, which support the conclusions of the analytical study, are reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Aggregation and release in thrombocytes of the duck (1975)

Avian thromboyctes are aggregated by a number of substances that cause platelet aggregation, and evidence suggests that this response is related to the release of serotonin (5-hydroxytryptamine, 5-HT) from intracellular granules. In this study duck thrombocytes released 5-HT during collagen-induced aggregation, but thrombocytes incubated with 14C-labeled adenine did not release radioactive adenine nucleotides. These results indicate the existence of a metabolic pool of adenine nucleotides that is separate from released constituents of the cell. No unlabeled adenine compounds were detected in the supernatants of aggregated thrombocytes indicating either the rapid alteration of released nucleotides or the absence of a specific release pool of adenine nucleotides. Finally there is no release of the intracellular enzyme markers, lactate dehydrogenase, beta-glucuronidase, and acid phosphatase, during collagen-induced aggregation. These findings suggest that avian thrombocytes exhibit a specific release reaction and that serotonin acts as the functional counterpart of ADP in platelet aggregation.

Mobile devices compatibility testing strategy via crowdsourcing (2018)

Purpose This paper aims to support small mobile application development teams or companies performing testing on a large variety of operating systems versions and mobile devices to ensure their seamless working. Design/methodology/approach This paper proposes a “hybrid crowdsourcing” method that leverages the power of public crowd testers. This leads to generating a novel crowdtesting workflow Developer/Tester- Crowdtesting (DT-CT) that focuses on developers and crowd testers as key elements in the testing process without the need for intermediate as managers or leaders. This workflow has been used in a novel crowdtesting platform (AskCrowd2Test). This platform enables testing the compatibility of mobile devices and applications at two different levels, high-level (device characteristics) or low-level (code). Additionally, a “crowd-powered knowledge base” has been developed that stores testing results, relevant issues and their solutions. Findings The comparison of the presented DT-CT workflow with the common and most recent crowdtesting workflows showed that DT-CT may positively impact the testing process by reducing time-consuming and budget spend because of the direct interaction of developers and crowd testers. Originality/value To authors’ knowledge, this paper is the first to propose crowdtesting workflow based on developers and public crowd testers without crowd managers or leaders, which light the beacon for the future research in this field. Additionally, this work is the first that authorizes crowd testers with a limited level of experience to participate in the testing process, which helps in studying the behaviors and interaction of end-users with apps and obtains more concrete results.
Identification of Genetic Markers Associated with Sow Reproductive and Longevity Traits (2009)

The length of a sow’s productive life (SPL) in a herd is an important component contributing to economic returns to pork producers. Reproductive performance, locomotion, and structural soundness are major factors influencing SPL. Due to low and moderate heritability of reproductive traits, marker assisted selection (MAS) may be an effective tool to reduce the culling rate of sows and thereafter improve SPL. In this study, 119 SNPs from 95 genes were examined in a commercial sow population with recorded reproductive traits for six parities. The association analyses revealed a number of potentially interesting genes associated with total number born, number born alive in the first and later parities, and with gestation length in several continual parities. These associated genes could be considered for marker assisted selection to improve SPL in commercial sow population.
"Turn Left At The Fairham Pub" Using Navigational Guidance to Reconnect Drivers With Their Environment (2016)

This paper explores how navigational guidance which references the world around the driver influences their experience of workload and environmental engagement on multiple journeys. In an on-road study thirty participants drove following three intersecting routes in the city of Nottingham, UK on two separate occasions, one week apart. In a between subjects design, participants followed navigational guidance from either: an existing navigation system (SatNav); or the semi-structured wayfinding prompts of an informed passenger. Results indicated that drivers following the navigational guidance of the informed passenger benefitted from lower workload overall which also reduced significantly on their second drive. Additionally, these drivers made significantly fewer errors on route and demonstrated superior survey knowledge compared to their SatNav counterparts. This evidence supports the case for enhanced route directions in future navigation devices, referencing the driver's environment in a manner that can reduce workload and navigation errors, whilst assisting in spatial knowledge development.
Chemical route to nano-engineered skutterudites (2003)

Atomic scale material design provides opportunities for developing thermoelectric materials with significantly improved figures of merit (ZT). The use of small particle size may also increase ZT, because of possible increases in the ratio of electrical conductivity to thermal conductivity and the thermopower. A novel chemical route is described for fabricating multi-component thermoelectric metal alloys as fine nanostructured powders. The different constituents are simultaneously precipitated from aqueous solution-thereby providing a precursor having a precise desired composition and uniform molecular scale mixing. Thermal treatment of the precursor included calcination in air and reduction by hydrogen. Nanophase skutterudite of CoSb/sub 3/ in reasonably high phase purity was thereby produced after thermal treatments at a temperature of 350-550/spl deg/C for only 3-5 hrs. High purity Ni-doped skutterudites of Co/sub 1-x/Ni/sub x/Sb/sub 3/ up to x=0.25 were also produced using this route.
Listener Experience and Perception of Voice Quality (1990)

Five speech-language clinicians and 5 naive listeners rated the similarity of pairs of normal and dysphonic voices. Multidimensional scaling was used to determine the voice characteristics that were perceptually important for each voice set and listener group. Solution spaces were compared to determine if clinical experience affects perceptual strategies. Naive and expert listeners attended to different aspects of voice quality when judging the similarity of voices, for both normal and pathological voices. All naive listeners used similar perceptual strategies; however, individual clinicians differed substantially in the parameters they considered important when judging similarity. These differences were large enough to suggest that care must be taken when using data averaged across clinicians, because averaging obscures important aspects of an individual's perceptual behavior.
Transition from Three-Dimensional Anisotropic Spin Excitations to Two-Dimensional Spin Excitations by Electron Doping the FeAs-Based<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:msub><mml:mi>BaFe</mml:mi><mml:mn>1.96</mml:mn></mml:msub><mml:msub><mml:mi>Ni</mml:mi><mml:mn>0.04</mml:mn></mml:msub><mml:msub><mml:mi>As</mml:mi><mml:mn>2</mml:mn></mml:msub></mml:math>Superconductor (2009)

We use neutron scattering to study the effect of electron doping on the structural or magnetic order in BaFe2As2. In the undoped state, BaFe2As2 exhibits simultaneous structural and magnetic phase transitions below 143 K. Upon electron doping to form BaFe1.96Ni0.04As2, the system first displays the lattice distortion near approximately 97 K, and then orders antiferromagnetically at 91 K before developing weak superconductivity below approximately 15 K. The effect of electron doping is to reduce the c-axis exchange coupling in BaFe2As2 and induce quasi-two-dimensional (2D) spin excitations. These results suggest that the transition from 3D spin waves to quasi-2D spin excitations by electron doping is important for the separated structural and magnetic phase transitions in iron arsenides.

Isolated<i>MYC</i>cytogenetic abnormalities in diffuse large B-cell lymphoma do not predict an adverse clinical outcome (2015)

In this study, we investigated the significance of MYC, BCL2 and BCL6 gene abnormalities in a cohort of 205 diffuse large B-cell lymphoma (DLBCL) patients studied by conventional and/or fluorescence in situ hybridization cytogenetic analysis. Combining these methods, 172 cases (84%) were classified as MYC-, 17 (8%) were MYC+/BCL2-/BCL6-, and 16 (8%) were double/triple-hit lymphomas (i.e. MYC+/BCL2+, MYC+/BCL6+, or MYC+/BCL2+/BCL6+). We found a significant difference in event-free survival (EFS) among the three groups (p = 0.02), with the double/triple-hit group having the worst EFS. Patients who were MYC+, but BCL2- and BCL6-, had the best EFS. We conclude that patients with MYC+ DLBCL, but without BCL2 or BCL6 abnormalities, do not have a worse outcome when compared to those who are MYC-. However, patients with double/triple-hit DLBCL have a very poor outcome and should be treated with aggressive or novel therapies.
SEU-Mitigation Placement and Routing Algorithms and Their Impact in SRAM-Based FPGAs (2007)

In this paper, the authors propose a new SEU-mitigative placement and routing of circuits in the FPGAs which is based on the popular VPR tool. The VPR tool is modified so that during placement and routing, decisions are taken with awareness of SEU-mitigation. Moreover, no redundancies during the placement and routing are used but the algorithms are based on the SEU avoidance. Using the modified tool, i.e., S-VPR, the role of placement and routing algorithms on the fault-tolerance of circuits implemented on FPGAs is achieved. The secondary propose of this paper is to find which of placement or routing is more suited for decreasing SEU sensibility of circuits and to find whether these SEU sensibility reductions are cumulative or not when they applied in sequence. We have investigated the effect of S-VPR on several MCNC benchmarks and the results of the placement and routing have been compared to the traditional one. The evaluations of results show that placement and routing can decrease the SEU rate of circuits implemented on FPGAs about 18% and 12%, respectively. However, it increases critical path delay and power consumptions of the circuits up to 5% and 8%, respectively. This means that without any redundancies, just by means of fault-avoidance method, mitigation of SEU effects would decrease up to 22% significantly and this method is notable compared to previous TMR and DWC mechanisms
Combination chemotherapy for advanced squamous cell carcinoma of the head and neck (1981)

Fifty-one patients (32 previously untreated, 19 previously treated) with advanced squamous cell carcinoma of the head and neck received a single course of combination chemotherapy consisting of high dose cis-platinum (DDP), bleomycin (Bleo), +/- high dose methotrexate (MTX). Thirty-three (65%) patients responded to therapy; 5 (10%) of these patients had a complete response. Previously untreated patients and those who received the three drugs (DDP, Bleo and MTX) had the highest response rates. The duration of response was 8 to 12 weeks. Seven (15%) patients showed a two-year survival rate. All nonresponders were dead of disease within two years. Three (56%) of the five complete-response patients and 4 (21%) of the partial-response patients survived for two years. The role of preoperative chemotherapy in head and neck cancer is yet to be conclusively defined.
Advancement of Puberty in the Female Rat by Estrogen (1965)

Puberty, as defined by vaginal opening, ovulation and the initiation of estrous cycles, has been advanced more than a week in the immature female rat by treatment with low, approximately physiological dosages of estrogen (estradiol benzoate, 0.05 μg/100 g body wt/day). These results were achieved either by short-term treatment with estrogen starting at 26 days of age or by withdrawal of estrogen after vaginal opening at 30 days of age following long-term treatment from day 5. To study the dynamics of gonadotrophin secretion under natural and precocious pubertal conditions, both pituitary and plasma LH levels were measured by the ovarian ascorbic acid depletion method. In early puberty induced by estradiol benzoate, as in natural puberty 7-9 days later, there was a sharp drop in pituitary LH coincident with an equally marked rise in plasma LH, confirming the release of the pituitary trophin into the blood. In the rat ovariectomized at 26 days and treated with estrogen for 4 days the pituitary LH remained elevated and the plasma level remained undetectable, suggesting that in the intact rat the estrogen stimulus may involve synergism with some other ovarian hormone such as progestin. Testosterone propionate in low dosages (10 μg/100 g body wt/day X5 days) precipitated neither ovulation nor the release of pituitary LH; the latter was undetectable in plasma and high in pituitary extracts. Inasmuch as exogenous estrogen causes the precocious appearance of brain-pituitaryovarian changes characteristic of natural puberty, the results suggest that endogenous estrogen may evoke these changes during the normal maturation process, and that the secretion of estrogen may constitute a key limiting factor in the natural onset of puberty.

Inhibition of nuclear factor kappa B subunit p65 mRNA accumulation in lipopolysaccharide‐stimulated human monocytic cells treated with sodium salicylate (1996)

Lipopolysaccharide is one of the most potent trigger substances for monocytes and macrophages causing secretion of inflammatory mediators such as tumor necrosis factor and interleukin-1. The nature of the nuclear factors involved in regulation of these cytokine genes is still unknown. Nuclear factor kappa B (NF-kappa B; heterodimer of p50 and p65) proteins have been suggested to play an important role in gene transcription of inflammatory mediators when monocytes are stimulated with lipopolysaccharide. Nonsteroidal anti-inflammatory drugs such as salicylates have been used to treat symptoms of inflammation, and a new mechanism of drug action was suggested recently. Salicylates have been shown to inhibit lipopolysaccharide-induced gene transcription via inhibition of NF-kappa B activation by preventing the degradation of NF-kappa B inhibitor "I kappa B", blocking the translocation of NF-kappa B into the nuclear compartment. However, the nature of the subunit involved in this mechanism has not been defined. To examine the mechanisms by which salicylates affect cytokine gene transcription, the amount of active and inactive NF-kappa B and NF-kappa B mRNA, in Porphyromonas gingivalis lipopolysaccharide-stimulated human monocytic cells was assessed. High doses of sodium salicylate suppressed NF-kappa B p65 mRNA accumulation, resulting in suppression of total NF-kappa B, p50 on tissue oligonucleotide had no effects on lipopolysaccharide-induced NF-kappa B activation. The data demonstrate that the p65 subunit of NF-kappa B is inhibited by salicylate treatment and highlight the role of salicylate in the control of gene expression of inflammatory mediators.
