Methodology for Power-Performance Trade-Off Management in Real-Time Embedded Applications (2022)

An increasing number of battery-powered devices that are used outdoors or in mobile systems put emphasis on the power and energy efficiency as a form of trade-off between application performance and system power consumption. However, lack of objective metrics for the evaluation of application performance degradation poses difficulties for managing such trade-offs in real-time applications. The proposed methodology introduces metrics for modeling of application performance and the technique for its control, enabling more efficient power–performance trade-off management. The methodology allows for selective system performance degradation and fine-grained control of system behavior in the power–performance domain by extending the set of operating point parameters controllable through real-time application. The utilization and the effectiveness of the proposed methodology is evaluated in a simulated environment for different scenarios of the application execution, including system operation above the utilization bounds.
Redundancy of the Lempel-Ziv codes (2002)

For unifilar, Markov sources, we demonstrate that the redundancy of encoding the first n letters of the source output with the Lempel-Ziv (1977) string matching code (LZ '77) is O((ln ln n)/(ln n)) and the redundancy with the Lempel-Ziv incremental parsing rule (LZ '78) is O(1/(ln n)); in both cases, we upper bound the exact form of convergence.
<title>Application of lasers for noncontact excitation and measurement of vibration</title> (2000)

This work is part of a research devoted to the development of a non-intrusive modal analysis procedure based on laser techniques both for excitation and for measurement. The attention is focused on the experimental evaluation of uncertainty sources in modal parameter measurement, when high energy laser pulses are used to excite the vibration of the structure. The tests were performed on a cantilever beam excited firstly with a hammer and then with laser pulses from a Nd-YAG source (532 nm, 100 mJ/pulse). The problem due to the lack of knowledge on laser-induced input force is here considered. This, in fact, makes the precise quantitative measurement of the mobility functions and of the damping ratio difficult. To this aim, an `equivalent' input force was estimated by solving an inverse problem: the `equivalent' force is useful to determine the features of the laser-induced impulsive excitation. The achieved results are in complete agreement with other characterizations presented in previous studies, in particular in terms of specific impulse, time duration and characteristic frequencies. Finally, several suggestions are given in order to minimize the influence of the problems connected with laser pulse excitation, in particular concerning the limited energy given to the structure under investigation.
A 105 dB SNR multibit ΣΔ ADC for digital audio applications (2002)

A four-channel multibit /spl Sigma//spl Delta/ analog-to-digital converter (ADC) for consumer audio applications is described. The converter uses a second order switched-capacitor modulator with a 4-bit quantizer and a noise-shaped scrambler for dynamic element matching. To achieve the target settling time with reduced power consumption, the opamps are dynamically compensated. A multi-stage decimation filter with adjustable front-end sine filter is used to produce the PCM output at a selectable sample rate of 48/96 kHz. The converter achieves an SNR and D-range of 105 dB (A-weighted), THD+N of -98 dB at 48 kHz sample rate. The circuit is implemented in 0.5 /spl mu/m DPTM CMOS, dissipating 90 mW per channels. The core die size is 1.6 mm/sup 2/ per channel.
An enzyme-linked immunosorbent assay for urinary albumin in patients with insulin-dependent diabetes mellitus. (1993)

Microalbuminuria is considered to be an early indicator of diabetic nephropathy. In this report, we developed an enzyme-linked immunosorbent assay (ELISA) for the measurement of urinary albumin (UA) and examined UA in 38 patients with insulin-dependent diabetes mellitus (IDDM). The assay range of ELISA for albumin was 5-1,000 ng/ml, and the albumin levels determined by ELISA were well correlated with those by immunoagglutination methods. The UA values of daytime single-void specimens in control subjects, which correlated significantly with UA excretion rates (micrograms/minute) in 24-hour urine, were 10.9 +/- 8.2 micrograms/mg creatinine. In 38 IDDM patients, there were four cases with microalbuminuria and one case with overt nephropathy. Their disease duration was longer than 8 years, and the diabetic control was fair to poor. On SDS-PAGE analysis. the urinary protein of the cases with microalbuminuria consisted mainly of albumin, and in the case of nephropathy, an IgG band was also detected. The measurements of UA in single-void specimens by ELISA is a satisfactory approach to detect impending nephropathy in IDDM patients.
Rank Wildcat Drilling Risks & Drilling Time Reduced in Ultra Deepwater Offshore Namibia with the Application of Seismic & Formation Pressure While Drilling Technology (2013)

Abstract Rank wildcat wells in Ultra deepwaterD- present some of the greatest challenges today. Decision making during drilling is challenging due to a lack of offset well data. 3D Surface seismic data has significant uncertainty from the translation of two-way time to horizon depths which further induces risk into the predrill pore pressure model. This paper looks in detail at how the utilization of a high-tech logging while drilling suite in the execution of a rank wildcat enabled key drilling decisions to be made, reducing risk and time vs. depth plan the well. Seismic while drilling technology guided drilling in each section from spudding to total depth by allowing up to 600 m look ahead. This reduced target depths uncertainty from +/-100 meters to less than +/-5meters. Furthermore it permittedallowed this complex S-shaped well trajectory to avoid accidental penetration into the first target avoiding well control situation, placing the 13 3/8?? casing shoe safely above the first target, 80m shallower than planned. This ensured an increased mud weight window for the 12.25?? section. In the 12.25?? section, Formation Pressure While Drilling Technology was added to the Seismic and Sonic technologies to calibrate the pre drill pore pressure model. This was critical due to a narrow mud weight. The acquired formation pressures coupled with while drilling petrophysical data allowed for the pore pressure to velocity transform and normal compaction trend lines to be calibrated reducing the uncertainty in the pore pressure model ahead of the bit. Uncertainty in depth of targets and modeled pressure ramps ahead of the bit were further reduced with the Seismic data.
Molecular profiles of response to neoadjuvant chemoradiotherapy in oesophageal cancers to develop personalized treatment strategies (2021)

Identification of molecular predictive markers of response to neoadjuvant chemoradiation could aid clinical decision-making in patients with localized oesophageal cancer. Therefore, we subjected pretreatment biopsies of 75 adenocarcinoma (OAC) and 16 squamous cell carcinoma (OSCC) patients to targeted next-generation DNA sequencing, as well as biopsies of 85 OAC and 20 OSCC patients to promoter methylation analysis of eight GI-specific genes, and subsequently searched for associations with histopathological response and disease-free (DFS) and overall survival (OS). Thereby, we found that in OAC, CSMD1 deletion (8%) and ETV4 amplification (5%) were associated with a favourable histopathological response, whereas SMURF1 amplification (5%) and SMARCA4 mutation (7%) were associated with an unfavourable histopathological response. KRAS (15%) and GATA4 (7%) amplification were associated with shorter OS. In OSCC, TP63 amplification (25%) and TFPI2 (10%) gene promoter methylation were associated with an unfavourable histopathological response and shorter DFS (TP63) and OS (TFPI2), whereas CDKN2A deletion (38%) was associated with prolonged OS. In conclusion, this study identified candidate genetic biomarkers associated with response to neoadjuvant chemoradiotherapy in patients with localized oesophageal cancer.
α1- andα2-Adrenoreceptor Antagonist Profiles of 1- and 2-[ω-(4-Arylpiperazin-1-yl)alkyl]-1,2,3-benzotriazoles (2005)

A series of pharmacologically interesting 1- and 2-[omega-(4-arylpiperazin-1-yl)alkyl]-1,2,3-benzotriazoles, compounds 1-27, were synthesized (Scheme) and subjected to various biological studies to identify structure-activity relationships (SAR). The new compounds were found to exhibit good non-selective binding affinity towards the alpha1-adrenoreceptor (Table 1). In several cases, high functional antagonism was observed towards the alpha1A-, alpha1B-, and alpha1D-adrenoreceptor subtypes (Table 2). The selectivity for these three subtypes was comparable with or superior to that displayed by the standard drug prazosin. The most-common selectivity rank order was alpha1D > alpha1B > alpha1A, followed by alpha1B > alpha1D > alpha1A. In functional experiments, antagonism towards the alpha2-adrenoreceptor was generally low; however, a few compounds were endowed with significant antagonist properties (pA2 values of up to 7.87).

We developed TCP, a tool for designing chimera proteins based on the tertiary structure information. TCP is robust and possesses several favourable features, and we believe it is a useful tool for designing chimera proteins. TCP is freely available as an additional file of this manuscript for academic and non-profit organization.
Photosensitization and Photocatalysis—Perspectives in Organic Synthesis (2018)

Photochemical sensitization and photocatalysis have very similar definitions and are closely related. Each of the two terms are preferentially used in different scientific communities. Three types of processes are discussed: (1) sensitization involving energy transfer, (2) photocatalysis in which hydrogen abstraction plays a key role, and (3) photoredox catalysis in which electron transfer is involved. The processes are discussed in connection with [2 + 2] photo-cycloadditions and C–H activation, which are of particular interest for organic synthesis.
An evaluation of multiple-disk I/O systems (1989)

Alternative ways of configuring an I/O subsystem with multiple disks to improve the I/O performance are considered. Specifically, the author consider disk synchronization, data declustering/disk striping, and a combination of both these approaches. They evaluate many different organizations that have not been considered before. The effects of block size and other parameters of the system are examined. Two different workloads are considered for the evaluation: a file/transaction system workload and a scientific applications workload. Through simulations it is shown that synchronized organizations perform better than other organizations at very low request rates; that there is a tradeoff in the amount of declustering/synchronization to be used in a system; and that systems with higher parallelism in reading a file perform better in a scientific workload.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
What is osteopenia, and what should be done about it? (2006)

Because the term “osteopenia” is not useful as a diagnosis and can actually be harmful, I am on a personal crusade to eliminate it from the bone density lexicon.
Compiler-controlled extraction of computation-communication overlap in MPI applications (2008)

Exploiting computation-communication overlap is a well- known requirement to speed up distributed applications. However, efforts till now use programmer expertise, rather than any automatic tool to do this. In our work we propose the use of an aggressive optimizing compiler (IBM's xl series) to automatically extract opportunities for computation communication overlap. We depend on aggressive inlining, dominator trees and SSA based use-def analyses provided by the compiler framework for exploiting such overlap. Our target is MPI applications. In such applications, we try to automatically move mpi_waits as well as split blocking mpi_send/recv to create more opportunities for overlap. Our objective is two-fold: firstly, our tool should relieve the programmer from the burden of hunting for overlap manually as much as possible, and secondly, it should aid in converging on parallel applications which benefit from such overlap quickly. These are necessary as MPI applications are quickly becoming complex and huge and manual overlap extraction is becoming cumbersome. Our early experience shows that it is not necessary that exploiting an overlap always leads to performance improvement. This corroborates with the fact that if we have an automatic tool, then, we can quickly discard such applications (or certain configurations of such applications) without spending person-hours to manually rewrite MPI applications for introducing non-blocking calls. Our initial experiments with the industry-standard NAS parallel benchmarks show that we can get small-to-moderate improvements by utilizing overlap even in such highly tuned benchmarks. This augurs well for real-world applications that do not exploit overlap optimally.
Effect of Sn Addition on Microstructure and Texture of Primarily Recrystallized 3 mass%Si Steel (1991)

A study was made on the effect of Sn addition on the structure and primary recrystallization texture of 3 mass%Si steel containing no inhibitors, which was processed by the single-stage cold rolling process. The following conclusions were obtained.(1) Sn addition decreases the size of primarily recrystallized grains and increases {110} density and the product of density of {110} and that of {111} in the primarily recrystallized texture. Consequently, it is considered that Sn addition has the effect of making secondary recrystallization easier and decreasing the size of secondarily recrystallized grains.(2) Sn addition increases the size of ferritic grains in the annealed hot-band, decreases the size of precipitates of carbides and uniforms the dispersion of them. In addition, the starting temperature of recrystallization after cold rolling shifts to the higher side. Sn is considered to segregate on grain boundaries in each stage from hot rolling to heating stage of final annealing. It is considered that these phenomena are related to a decrease of the size of primarily recrystallized grains and an increase of the {110} density in the primarily recrystallized texture.
Effect of maternal weight, adipokines, glucose intolerance and lipids on infant birth weight among women without gestational diabetes mellitus (2012)

Among women without gestational diabetes, maternal adiposity and leptin levels were the strongest metabolic determinants of having a large-for-gestational-age infant rather than glucose intolerance and lipid levels.
"Lamyai" teaches young Thai women about AIDS and STDs. (1994)

The young women 13-21 years of age who migrate in large numbers from villages in Northern Thailand to obtain employment in urban factories comprise a group at high risk of human immunodeficiency virus (HIV) infection. To encourage these women to protect themselves from infection, workplace projects were developed in textile factories in Chiang Mai. Pre-project research conducted among 250 female factory workers revealed good awareness of acquired immunodeficiency syndrome (AIDS) coupled with a perception of personal invulnerability and a reluctance to request that partners use condoms due to fears of being considered promiscuous. To address these issues, a romantic illustrated novel about a factory worker who is infected with the AIDS virus by her fiance and a humorous comic book featuring "Brother Protector Condom" were prepared. The materials were introduced to groups of 10 or more women led by either trained peer educators or health promoters. Participants overcame initial shyness about the explicit pictures and reported the group meetings gave them confidence to talk to their sexual partners about condom use. Post-intervention evaluation showed that peer-led groups were most effective in improving self-esteem, communication skills, and commitment to AIDS prevention. Although the health promoters had more in-depth knowledge of AIDS and human reproduction, they tended to lecture rather than facilitate discussion. Moreover, the age and educational differences between the factory workers and health promoters impeded the trust and open discussion that developed in peer-led groups.
Mechanical behavior of a Ti‐6Al‐4 V titanium alloy with microstructural evolution modeling under hot and superplastic conditions (2017)

Abstract The present work aims at evaluating and understanding the mechanical behavior of a Ti‐6Al‐4 V alloy under hot and superplastic forming conditions. Tensile tests were performed at temperature range from 650 °C to 950 °C, at strain rates between 10 ‐2 s ‐1 and 10 ‐4 s ‐1 . Three equiaxed microstructures, each characterized by a different starting grain size (4.9 μm, 3.0 μm and 0.5 μm), are compared to better understand the microstructural evolutions under hot and superplastic forming conditions and their influence on the mechanical behavior. Hence, an accurate model with microstructural considerations is proposed. The model capabilities consider the grain size evolution that is influenced by the temperature and deformation. The computed flow stresses strongly depend on the strain rate and on the considered initial grain size. Temperature and strain rate conditions may lead to a strain hardening phenomenon in some cases. The comparison between the model response and experiment shows a good agreement for all the tests carried out on Ti‐6Al‐4 V.
Interstitial ice formation in cryopreserved homografts: a possible cause of tissue deterioration and calcification in vivo. (2000)

It is proposed that the extensive ice formation observed in conventionally cryopreserved heart valves may cause extracellular matrix damage that predisposes the valves to calcification. Future studies will assess the above hypothesis by comparison of conventional and ice-free (vitrification) cryopreservation methods in animal models of calcification.
Efficacy of Dry Ice-Baited Traps for Sampling Amblyomma americanum (Acari: Ixodidae) Varies With Life Stage But Not Habitat (2011)

The carbon dioxide-baited trap is the most common and effective method for sampling vector life-stage Amblyomma americanum (L.) (Acari: Ixodidae), although confounding environmental variables are rarely considered. A mark-recapture experiment was designed to compare recapture proportions of A. americanum nymphs and adults between two habitat types: old field and oak-hickory forest. Powdered fluorescent dye was used to mark A. americanum ticks released in 1-m increments from carbon dioxide-baited traps. Adults were recaptured in significantly higher proportion than nymphs, but habitat type had no significant effect on recapture proportions. Tick abundance is an important parameter in the estimation of human risk of exposure to tick-borne disease and the influence of life stage on capture rates should be considered when calculating entomological risk.
Structural, Thermodiffusive and Thermoelectric Properties of Maghemite Nanoparticles Dispersed in Ethylammonium Nitrate (2020)

Ethylammonium nitrate (ionic liquid) based ferrofluids with citrate-coated nanoparticles and Na + counterions were synthesized for a wide range of nanoparticle (NP) volume fractions ( Φ ) of up to 16%. Detailed structural analyses on these fluids were performed using magneto-optical birefringence and small angle X-ray scattering (SAXS) methods. Furthermore, the thermophoretic and thermodiffusive properties (Soret coefficient S T and diffusion coefficient D m ) were explored by forced Rayleigh scattering experiments as a function of T and Φ . They were compared to the thermoelectric potential (Seebeck coefficient, Se) properties induced in these fluids. The results were analyzed using a modified theoretical model on S T and Se adapted from an existing model developed for dispersions in more standard polar media which allows the determination of the Eastman entropy of transfer ( S ^ NP ) and the effective charge ( Z 0 e f f ) of the nanoparticles.
Citrate anticoagulation for continuous venovenous hemofiltration* (2009)

The efficacy of citrate and nadroparin anticoagulation for CVVH was similar, however, citrate was safer. Unexpectedly, citrate reduced mortality. Less bleeding could only partly explain this benefit, less clotting could not. Post hoc citrate appeared particularly beneficial after surgery, in sepsis and severe multiple organ failure, suggesting interference with inflammation.
Development of a two-matrix composite material fabricated by 3D printing (2017)

A new technological process for the synthesis of composite materials based on carbon fibers and the combination of a thermoset and a thermoplastic matrix is described. The mechanical characteristics of a two-matrix composite are presented. The scope of its application is discussed.
A DRAMATIC INCREASE IN THE INCIDENCE OF HUMAN TRICHINELLOSIS IN ROMANIA OVER THE PAST 25 YEARS: IMPACT OF POLITICAL CHANGES AND REGIONAL FOOD HABITS. (2007)

According to the International Commission on Trichinellosis survey in 2004, Romania has the most cases of trichinellosis in the world. Epidemiologic data for each county were collected and analyzed from two different time periods: before (1980-1989) and after (1990-2004) political changes. Data were analyzed separately for Transylvania and the rest of the Romanian counties. During the past 25 years, 28,293 human cases of trichinellosis were reported with an incidence of 51.0 cases per 10(6) persons per year. An important increase in the incidence was observed from 1980 to 1989 compared with the 1990-2004 period. For the entire period, the incidence rate obtained for Transylvanian counties (82.2 cases per 10(6) persons per year) was higher than the incidence rate obtained for the other counties (35.7 cases per 10(6) persons per year). Hypotheses and facts contributing to the heterogeneity of human trichinellosis cases are discussed.
