Market based operation and planning - simulation and analysis (1999)

The author describes how, in the deregulated electricity market, much power will be traded in regional commodity exchanges. He argues that: electricity traders will need good bidding strategies to survive in competitive trading; and fuzzy logic provides a means of building adaptive bidding strategies. Current research has shown that genetic algorithms provide a convenient way of fine tuning and testing various bidding strategies and that GAs can also be used to perform intelligent data mining and can infer other's bidding rules.

Towards Trusted Location SpecificInformation for Cloud Servers (2017)

Every physical datacenter is located somewhere on the globe. It is subject to the local legislation, including data protection related laws. A cloud service can be delivered from a set of datacenters in several locations. Responsibilities of the service provider include ensuring that legal and agreed constraints are respected also by its subcontractors, for example, those providing cloud computing resources. Several countries have data protection legislation that restrict sharing copies of sensitive data to locations that do not have compliant legislation. This paper presents ideas to dependably detect location specific information, like the legislation properties, of the current physical host server executing a service.
Micro‐Photovoltaics: Dust‐Sized High‐Power‐Density Photovoltaic Cells on Si and SOI Substrates for Wafer‐Level‐Packaged Small Edge Computers (Adv. Mater. 49/2020) (2020)

Advancement in microelectronics technology enables autonomous edge computing platforms the size of a dust mote. In article number 2004573, Ning Li and co-workers show that dust-sized photovoltaic cells on a Si substrate can be integrated using a wafer-level-packaging process with other chiplets to achieve high efficiency and high power density. This advancement unlocks the potential of large-scale manufacturing of these compact integrated systems with high performance and low cost.
Infrared spectroscopic study of atomic layer deposition mechanism for hafnium silicate thin films using HfCl2[N(SiMe3)2]2 and H2O (2004)

In situ Fourier transform infrared (FT-IR) spectroscopy was used to study the atomic layer deposition mechanism of hafnium silicate films with dichlorobis[bis(trimethylsilyl)amido] hafnium (HfCl2[N(SiMe3)2]2) and water. The surface species was monitored during atomic layer deposition using vacuum chambers designed for in situ FT-IR spectroscopy studies. Vibrational spectroscopy reveals the gain and loss of surface species during the two surface half-reactions. The behavior of the functional group (such as O–Η, Si–(CH3)x, and C–H was monitored and from that, the temperature dependence of the growth rate and the film composition could be explained. It was also found that Si–O–Si peaks between 1000 and 1200cm−1 were formed when water was dosed above 300°C, which could explain the incorporation mechanism of Si into the film.
[Usefulness of transesophageal stimulation in the evaluation of sinus node function in patients with sick sinus syndrome]. (1988)

The purpose of this study was to find out whether transesophageal pacing could be utilized for assessment of sinus node function, besides Wenckebach point, in patients with sick sinus syndrome. In 17 patients with sino-atrial disease (group I) we compared the results of sinus node tests obtained both in the basal state and after pharmacological autonomic blockade by endocavitary stimulation and 24 hours later, by transesophageal pacing. In another group of 17 patients with sino-atrial disease (control group) we compared the results obtained from two endocavitary studies. In group I, sinus cycle length and corrected sinus recovery time did not show significant differences between the two studies either the basal state or after autonomic blockade, whereas sino-atrial conduction time was more prolonged during esophageal pacing (P less than 0.01). In the control group, sinus node measures did not show significant differences between the two studies. In group I, the following coefficients of correlation were obtained: A) in the basal state sinus cycle length, r = 0.65, corrected sinus recovery time, r = 0.57, sinoatrial conduction time, r = 0.52; B) after autonomic blockade sinus cycle length, r = 0.95, corrected sinus recovery time, r = 0.62 and sino-atrial conduction time, r = 0.53. In the basal state, the correlation for sinus cycle length and corrected sinus recovery time between the two studies was lower in the "study group" than in the "control group" (P less than 0.05). However, after autonomic blockade the correlation for sinus node measures did not show any significant differences between the two groups of patients.(ABSTRACT TRUNCATED AT 250 WORDS)

4.7 A 2.1Mpixel organic-film stacked RGB-IR image sensor with electrically controllable IR sensitivity (2017)

The use of infrared (IR) imaging to view scenes otherwise invisible to the human eye, simultaneously with visible-spectrum imaging, is increasingly of interest for various applications for such as in-vehicle, surveillance, and agricultural security cameras. The loss of spatial resolution in conventional RGB-IR sensors causes aliasing, because IR pixels are segmented within the provided effective pixel area [1,2]. 3-D stacking of photodiode arrays has been reported as another strategy for RGB-IR capture [3]; however, the need for bonding accuracy limits pixel size. Silicon's weak IR light absorptivity also results in relatively lower IR sensitivity on the part of these image sensors.
Opportunistic Third-Party Backhaul for Cellular Wireless Networks (2013)

With high capacity air interfaces and large numbers of small cells, backhaul -- the wired connectivity to base stations -- is increasingly becoming the cost driver in cellular wireless networks. One reason for the high cost of backhaul is that capacity is often purchased on leased lines with guaranteed rates provisioned to peak loads. In this paper, we present an alternate \emph{opportunistic backhaul} model where third parties provide base stations and backhaul connections and lease out excess capacity in their networks to the cellular provider when available, presumably at significantly lower costs than guaranteed connections. We describe a scalable architecture for such deployments using open access femtocells, which are small plug-and-play base stations that operate in the carrier's spectrum but can connect directly into the third party provider's wired network. Within the proposed architecture, we present a general user association optimization algorithm that enables the cellular provider to dynamically determine which mobiles should be assigned to the third-party femtocells based on the traffic demands, interference and channel conditions and third-party access pricing. Although the optimization is non-convex, the algorithm uses a computationally efficient method for finding approximate solutions via dual decomposition. Simulations of the deployment model based on actual base station locations are presented that show that large capacity gains are achievable if adoption of third-party, open access femtocells can reach even a small fraction of the current market penetration of WiFi access points.
Análise das prevalências de doenças detectadas pelo programa nacional de triagem neonatal no município de Araraquara no ano de 2009 (2014)

The National Neonatal Screening Program (NNSP) set up in all Brazil, aims, through planned phases of local implementation, to detect diseases such as phenylketonuria, congenital hypothyroidism, hemoglobinopathies and cystic fibrosis. The aim of this study was to assess, through a cross-sectional observational study, the prevalence of the diseases detected by the NNSP in the city of Araraquara, in records issued by the São Paulo APAE laboratory in the period between April and December 2009.The results show that Araraquara had a prevalence of phenylketonuria and congenital hypothyroidism 0.06% above the national averages of 0.01% and 0.03% respectively. With respect to hemoglobinopathies, the prevalence of sickle cell trait was 2.15% below the national average of 2.6%. The prevalence of Hb C in the city was 0.57%, similar to national values reported in the literature. Confirmed Hb Bart's had a prevalence of 0.13% in Araraquara, below the average of 0.38% for the surrounding region. The neonatal screening by heel-prick test and counseling for caregivers are important factors in reducing morbidity related to the evolution of these diseases.
Ultimate Power Limits of Optical Fibers (2010)

Past, Present and Future of Fullerene Nanotubes: Buckytubes (2005)

Carbon fibers having nanoscale dimensions have been known for well over a hundred years. In 1889, a U.S. patent was awarded to Hughes and Chambers for teaching a method for growing carbon filaments from ‘swamp gas’ — primarily methane — using a metallic crucible which, unwittingly, catalyzed the reaction [1]. Until the 1970s, the formation of such carbon nanofibers (also known as, carbon filaments or filamentous carbon) was mostly regarded as an undesirable side reaction in processes such as Fischer—Tropsch or steam-methane reforming reactions. Nanofibers were a nuisance: now we know better.
A Scalable Method for Access Control in Location-Based Broadcast Services (2008)

One important problem for public broadcast Location-Based Services (LBS) is to enforce access control on a large number of subscribers. In such a system a user typically subscribes to a LBS for a time interval (a, b) and a spatial region (x <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">bl</sub> , y <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">bl</sub> , x <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ir</sub> , y <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">tr</sub> ) according to a 3-dimensional spatial-temporal authorization model. In this paper, we argue that current approaches to access control using group key management protocols are not scalable. Our proposal STauth minimizes the number of keys which needs to be distributed and is thus scalable to a much higher number of subscribers and the dimensionality of the authorization model. We analytically and experimentally demonstrate the performance and scalability benefits of our approach against other group key management protocols.

Photoluminescence of Self‐organized Perylene Bisimide Polymers (2004)

Abstract Summary: Three polymers consisting of alternating perylene bisimide chromophores and flexible polytetrahydrofuran segments of different length have been studied using absorption and (time‐resolved) photoluminescence spectroscopy. In o ‐dichlorobenzene, the chromophores self organize to form H‐like aggregates. The photoluminescence spectra of the self‐organized polymers consist of vibronically resolved monomeric perylene bisimde fluorescence ( λ max = 538 nm, τ = 3.9 ns) and unstructured excimer‐type emission ( λ max = 635 nm, τ = 17 ns). An additional short‐lived ( τ ≈ 2 ns) luminescence component is observed and ascribed to the dynamic deactivation of the monomeric photoexcited state via excimer formation or energy transfer.

Manufacturing Additively, With Fresh Concrete (2013)

This research explores mega-scale additive manufacturing, using fresh concrete. In traditional concreting, rigid forms mold and protect young concrete, like an exoskeleton. Typically, these forms are not removed until the maturing material has developed considerable load-bearing strength. Conversely, Contour Crafting, an automated construction technology under development at the University of Southern California, proposes to rapidly fabricate civil structures additively — layering continuous ribbons of fresh unconfined concrete. The process, which is akin to 3-D printing, leverages a special polymer-modified concrete which is both highly workable and shape–stable. However, without exoskeleton, the freshly layered concrete must be load-bearing immediately upon placement. This is an unprecedented structural requirement, and little has been done to substantiate uncured concrete as a load-bearing member. This research establishes the build rates and material health monitoring necessary to erect these structures safely, and demonstrates the Contour Crafting process is viable.
Synthesis and characterization of novel polyaspartimides derived from 2,2?-dimethyl-4,4?-bis(4-maleimidophenoxy)biphenyl and various diamines (1999)

A novel bismaleimide, 2,2′-dimethyl-4,4′-bis(4-maleimidophenoxy)biphenyl, containing noncoplanar 2,2′-dimethylbiphenylene and flexible ether units in the polymer backbone was synthesized from 2,2′-dimethyl-4,4′-bis(4-aminophenoxy)biphenyl with maleic anhydride. The bismaleimide was reacted with 11 diamines using m-cresol as a solvent and glacial acetic acid as a catalyst to produce novel polyaspartimides. Polymers were identified by elemental analysis and infrared spectroscopy, and characterized by solubility test, X-ray diffraction, and thermal analysis (differential scanning calorimetry and thermogravimetric analysis). The inherent viscosities of the polymers varied from 0.22 to 0.48 dL g−1 in concentration of 1.0 g dL−1 of N,N-dimethylformamide. All polymers are soluble in N-methyl-2-pyrrolidone, N,N-dimethylacetamide, N,N-dimethylformamide, dimethylsulfoxide, pyridine, m-cresol, and tetrahydrofuran. The polymers, except PASI-4, had moderate glass transition temperature in the range of 188°–226°C and good thermo-oxidative stability, losing 10% mass in the range of 375°–426°C in air and 357°–415°C in nitrogen. © 1999 John Wiley & Sons, Inc.

Decline in Incidence of Epidemic Glucose Intolerance in Nauruans: Implications for the “Thrifty Genotype” (1991)

Trends in the prevalence and incidence of non-insulin-dependent diabetes mellitus and impaired glucose tolerance were studied in Micronesian Nauruans aged 20 years and above, by linking glucose tolerance data collected during population surveys performed in 1975/1976, 1982, and 1987. Based on World Health Organization criteria, the age-standardized prevalence of non-insulin-dependent diabetes mellitus has remained relatively constant (24.0% in 1987), but the prevalence of impaired glucose tolerance has decreased significantly from 21.1% (95% confidence interval (CI) 17.0-25.3) in 1975/1976 to 8.7% (95% CI 7.1-10.3) in 1987. Between the periods 1975/1976-1982 and 1982-1987, the incidence of progression from normal glucose tolerance to either impaired glucose tolerance (incidence rate ratio (IRR) = 0.55, p less than 0.01) or non-insulin-dependent diabetes (IRR = 0.46, p less than 0.05) has decreased dramatically, while progression from impaired glucose tolerance to non-insulin-dependent diabetes has increased (IRR = 1.23). The overall age-standardized incidence of non-insulin-dependent diabetes has declined from 26.2 cases/1,000 person-years in 1975/1976-1982 to 22.5 cases/1,000 person-years in 1982-1987. As there were no changes in the frequency of recognized risk factors, the decline in incidence of glucose intolerance is probably due to the intensity of the epidemic in Nauru, which has already removed a high proportion of the genetically susceptible individuals from the pool with normal glucose tolerance. Coupled with the observations that mortality is higher and fertility lower in diabetic Nauruans across the age range, the observed decline in the incidence and prevalence of non-insulin-dependent diabetes mellitus and impaired glucose tolerance may presage a fall in the population frequency of the diabetic genotype, at least in its more severe form, as might be predicted on the basis of Neel's "thrifty genotype" hypothesis.
Design of FBAR filters at high frequency bands (2006)

This article presents a study about the design of film bulk acoustic wave resonator (FBAR) filters at higher frequency bands. FBAR filters are expected to replace traditional filter technologies (SAW and ceramic). This is mainly due to their compatibility with silicon low-cost process, enabling mass production and filter integration on above-IC processes. Nonetheless, increasing the operation frequency of FBAR filters, new acoustical and electromagnetic constraints are introduced to the filter design. These new constraints of designing of FBAR filters are presented. Further, a design technique using higher harmonic modes is addressed. This technique enables the realization of FBAR filters for operation at higher frequency bands (X, Ku, K, and Ka) using the same fabrication conditions of FBAR filters in L, S, and C bands. © 2006 Wiley Periodicals, Inc.

A reconstruction method for equidistant fan beam differential phase contrast computed tomography (2011)

We report a reconstruction method, called a back-projection filtered (BPF) algorithm, for fan beam differential phase contrast computed tomography (DPC-CT) with equidistant geometrical configuration. This work comprises a numerical study of the algorithm and its experimental verification with a three-grating interferometer and an x-ray tube source. The numerical simulation and experimental results demonstrate that the proposed method can deal with several classes of truncated datasets. It could be of interest in future medical phase contrast imaging applications.
Photooxidation of Poly(phenylene oxide) Polymer (1985)

Poly(2,6-dimethyl-1,4-phenylene oxide) has been found to undergo photooxidation not at the benzylic methyl groups but rather across the aromatic ring. The mechanism is an electron-transfer reaction leading to a polymer radical cation (Ar+·) and superoxide (O2-·) which combine to give oxidatively degraded polymer. Sensitization, quenching, radical trapping and flash photolysis experiments support this mechanism.

Image-based pupil plane characterization via a space-domain basis (2017)

Aberration characterization plays a critical role in the development of any optical system. State-of-the-art lithography systems have the tightest aberration tolerances. We present an approach to image-based pupil plane amplitude and phase characterization using models built with a space-domain basis, in which aberration effects are separable. A polynomial model is constructed between the projections of the image intensity for chosen binary mask targets onto this basis and pupil amplitude or phase variation. This method separates model building and pupil characterization into two distinct steps, thus enabling rapid pupil characterization following data collection. The basis is related to both the transmission cross-coefficient function and the principal components of the image intensity. The pupil plane variation of a zone-plate lens from the Semiconductor High-NA Actinic Reticle Review Project (SHARP) at Lawrence Berkeley National Laboratory is examined using this method. Results are compared to pupil plane characterization using a previously proposed methodology where inverse solutions are obtained through an iterative process involving least-squares regression.
[Prognostic significance of syncope in patients with Wolff-Parkinson-White syndrome]. (1990)

The prognostic value of syncope in symptomatic patients with Wolff-Parkinson-White syndrome (WPW) is unknown. Therefore, in order to evaluate the sensibility, specificity, positive and negative predictive value of syncope and compare those values with the one obtained for the shortest RR interval (less than or equal to 250 msec) as well as for the anterograde refractory period of the accessory pathway (less than 270 msec), we reviewed the clinical and electrophysiological data of 158 symptomatic patients with WPW. Fourty-eight patients (30%) reported at least one episode of syncope, and 24 out of 158 patients experienced an aborted sudden death, probably due to rapid conduction via the accessory pathway during atrial fibrillation. Syncope has poor sensibility but high specificity in recognizing an aborted sudden death. However, the syncope demonstrated it had a lower prognostic value when compared with other electrophysiological parameters in correctly identifying patients with a history of ventricular tachycardia and/or fibrillation. In conclusion, the data of this study propose the symptom "syncope" as a frequent event in the history of symptomatic patients with WPW referred to electrophysiological study. Generally its presence does not correctly identify patients who experienced an aborted sudden death. Furthermore, its prognostic value is significantly lower than a shorter RR interval (less than or equal to 250 msec) during atrial fibrillation and an anterograde effective refractory period less than 270 msec.
