Survey in Smart Grid and Smart Home Security: Issues, Challenges and Countermeasures (2014)

The electricity industry is now at the verge of a new era-an era that promises, through the evolution of the existing electrical grids to smart grids, more efficient and effective power management, better reliability, reduced production costs, and more environmentally friendly energy generation. Numerous initiatives across the globe, led by both industry and academia, reflect the mounting interest around not only the enormous benefits but also the great risks introduced by this evolution. This paper focuses on issues related to the security of the smart grid and the smart home, which we present as an integral part of the smart grid. Based on several scenarios, we aim to present some of the most representative threats to the smart home/smart grid environment. The threats detected are categorized according to specific security goals set for the smart home/smart grid environment, and their impact on the overall system security is evaluated. A review of contemporary literature is then conducted with the aim of presenting promising security countermeasures with respect to the identified specific security goals for each presented scenario. An effort to shed light on open issues and future research directions concludes this paper.
Population‐based prostate‐specific antigen testing in the UK leads to a stage migration of prostate cancer (2009)

Population-based PSA testing resulted in a significant downward stage and grade migration, and most such cancers were of low stage and grade, which could lead to risks of over-treatment for some men.
Nickel ferrite nanoparticles: elaboration in polyol medium via hydrolysis, and magnetic properties (2004)

Ultrafine magnetic nickel ferrite NiFe2O4 particles of high crystallinity were directly prepared by forced hydrolysis of ionic iron (III) and nickel (II) solutions in 2-hydroxyethyl ether at about 478 K under atmospheric pressure. The resulting nickel ferrite particles exhibit very interesting magnetic properties: they are superparamagnetic at room temperature and have a saturation magnetization close to that of the bulk at low temperature. An in-field Mossbauer study shows clearly that this surprising behaviour is mainly due to: (i) a departure of the cation distribution from the classical distribution encountered in the bulk material and (ii) the absence of spin canting for both tetrahedral and octahedral cations.
THROMBOCYTOSIS IN PATIENT WITH SEVERE ASTHMATIC ATTACK (1991)

We observed the remarkable thrombocytosis in a patient suffering from severe asthmatic attack. The number of platelets decrease gradually along with the improvement of the symptome Thromboelastogram showed the accelation of coagulation and thrombocytosis. However thrombocyte function was normal judging from the result of coagulation function test. Furthermore, we aloso observed the number of the platelets in the patients suffering from astmatic attack was significantly higher than that of healthy children, suggesting the involvement of platelets in asthmatic attack as a inflamation.
MR imaging of mediastinal lymph nodes: Evaluation using a superparamagnetic contrast agent (2000)

The purpose of this study was to determine whether intravenous injection of a magnetic resonance (MR) contrast agent, ultrasmall superparamagnetic iron oxide (ferumoxtran-10), can be useful in characterizing lymph nodes in patients with lung cancer. Twelve patients with known or suspected lung cancer were studied. Pre- and postcontrast injection of ferumoxtran-10 MR scans of the chest were obtained. Analysis of the signal intensities and bronchoscopic fine needle aspiration of a single node were performed in each patient. Six of 12 patients had a final diagnosis of lung cancer. T1-weighted images were best for localizing mediastinal lymph nodes. Signal intensity changes before and after contrast were best visualized on T2-weighted and gradient-echo images. All four patients with lung cancer who had nodes positive for malignancy at biopsy had no change in signal intensity of the nodes on T2 images. The signal intensity decreased in the remaining two patients, and the nodes were benign. Of the eight patients with benign disease, five had no change in signal intensity of the nodes. Therefore the sensitivity for tumor involvement of the nodes is 100%, but the specificity is only 37.5%. Ferumoxtran-10 is a contrast agent that can alter the signal intensity of lymph nodes. Lack of signal change may be due to malignant or inflammatory change. Studies in a larger population of lung cancer patients may help to characterize the utility of this agent further. J. Magn. Reson. Imaging 2000;12:899-904.
EF-P Is Essential for Rapid Synthesis of Proteins Containing Consecutive Proline Residues (2012)

Elongation factor P (EF-P) is a translation factor of unknown function that has been implicated in a great variety of cellular processes. Here, we show that EF-P prevents ribosome from stalling during synthesis of proteins containing consecutive prolines, such as PPG, PPP, or longer proline strings, in natural and engineered model proteins. EF-P promotes peptide-bond formation and stabilizes the peptidyl-transfer RNA in the catalytic center of the ribosome. EF-P is posttranslationally modified by a hydroxylated β-lysine attached to a lysine residue. The modification enhances the catalytic proficiency of the factor mainly by increasing its affinity to the ribosome. We propose that EF-P and its eukaryotic homolog, eIF5A, are essential for the synthesis of a subset of proteins containing proline stretches in all cells.
Characterization of the integration site of Yersinia high-pathogenicity island in Escherichia coli (1999)

The high-pathogenicity island (HPI) of virulent Yersiniae consists of (i) a functional core encoding for biosynthesis and uptake of the siderophore yersiniabactin and (ii) a 5- to 13-kb AT-rich region of unknown function. This Yersinia HPI has been shown to be widely distributed among different pathotypes of Escherichia coli. In this study, the insertion site of the HPI was defined in three different E. coli strains: The enteroaggregative E. coli (EAggEC) strain 17-2, the uropathogenic (UPEC) E. coli strain 536, and the probiotic E. coli DSM6601. We demonstrated that in all three E. coli isolates the HPI is associated with the asnT tRNA (5′-extremity) and truncated in the AT-rich region (3′-extremity) since the 17-bp direct repeat (DR) of the asn tRNA that flanks the HPI in Yersinia is missing in E. coli. Moreover, in comparison to the HPI-negative E. coli K-12 strain, a uniform deletion must have taken place in the E. coli chromosome adjacent to the 3′-border of the HPI.
Favourable Influences of Linoleic Acid on the Progression of Diabetic Micro- and Macroangiopathy (1980)

A long-term study of two diets on the progression of diabetic retinopathy was performed on 102 patients. Diet 1 was composed of carbohydrates 50 cal%, saturated fats 35 cal%, proteins 15 cal%; diet 2, of carbohydrates 45 cal%, fats 40 cal% (are third linoleic acid) and proteins 15 cal%. The linoleic acid content of diet 2 was 4 times that of diet 1. The diabetics were matched 2 by 2 according to 10 criteria and set at random on one of the two diets. During the observation period of 5 years, 3 patients of diet 1 died of a heart infarction. Of the remaining 96 patients (51 males and 44 females); of diet group 1 (linoleic acid poor), 62% of the males and 55% of the females showed retinopathy. Of diet group 2 (linoleic acid rich), 27% of the males and 32% of the females showed retinopathy (p < 0.00l). A strong inverse correlation was found between progression of retinopathy and serum cholesteryl linoleate. Of diet group 1, 11 males and 7 females showed signs of cardiac ischaemia, of diet group 2, 3 males and 2 females (p < 0.025) did so. Large differences were seen for the GTTs and corresponding insulin levels between males and females. While the females of diet group 2 improved remarkably in respect of GTTs and reactive serum insulins, a slow deterioration of both parameters was seen for diet group 1. Regarding the males, no differences between the two diet groups were seen. The improvements due to the treatment were similar. The serum lipid responses were significant for the females, diet group 2 showed the lowest levels; however, no differences were seen for the males. In most cases of both sexes, platelet aggregation was increased, no effects of linoleic acid was seen: an explanation for the contradictory facts was not given.
Bradykinin Antagonists Do Not Require a D-Aromatic Amino Acid Residue at Position 7 (1992)

More than 200 new analogs of bradykinin have been synthesized and assayed. Analogs containing a D-aliphatic amino acid residue at position 7 and an L-aliphatic residue at position 8 are very potent antagonists of BK action on classical systems. Thus the "conventional wisdom" that a D-aromatic amino acid residue is required at sequence position 7 of BK antagonists must be modified.
Excitation of Hypersonic Vibrations by Means of Photoelastic Coupling of High-Intensity Light Waves to Elastic Waves (1965)

A theory of the excitation of elastic waves arising from photoelastic coupling with light is presented. It is similar in character to the theory of optical parametric amplification in spatially extended media. Special attention is given to the self-excited transient case. A novel form for the space—time development of the instability appears for the case in which the spatial dimensions of the interaction region are large compared to the distance traveled by an elastic wave during the illumination time. The predicted effects should be readily observable with existing giant pulse lasers.
Understanding colloidal charge renormalization from surface chemistry: Experiment and theory (1994)

In this paper we report on the charging behavior of latex particles in aqueous suspensions. We use static light scattering and acid–base titrations as complementary techniques to observe both effective and bare particle charges. Acid–base titrations at various ionic strengths provide the pH dependent charging curves. The surface chemical parameters (dissociation constant of the acidic carboxylic groups, total density of ionizable sites and Stern capacitance) are determined from fits of a Stern layer model to the titration data. We find strong evidence that the dissociation of protons is the only specific adsorption process. Effective particle charges are determined by fits of integral equation calculations of the polydisperse static structure factor to the static light scattering data. A generalization of the Poisson–Boltzmann cell model including the dissociation of the acidic surface groups and the autodissociation of water is used to predict effective particle charges from the surface chemical parameters determined by the titration experiments. We find that the light scattering data are best described by a model where a small fraction of the ionizable surface sites are sulfate groups which are completely dissociated at moderate pH. These effective charges are comparable to the predictions by a basic cell model where charge regulation is absent.
Exogenous effects and endogenous production of endothelin in cardiac myocytes: potential significance in heart failure (1996)

Increased plasma concentrations of endothelin have been identified in patients and animals with severe congestive heart failure (CHF). However, whether and to what extent increased endothelin (ET) concentrations influence left ventricular (LV) myocyte contractility, ET-receptor subtype density, and endogenous ET production with the development of CHF remains unclear. Accordingly, myocyte contractile function, response to ET, sarcolemmal ET-receptor density, and myocyte ET production were examined in pigs following the development of pacing-induced CHF (240 beats/min, 3 wk, n = 8) and in controls (n = 8). With CHF, plasma ET increased over threefold. In the presence of ET (10-500 pM), myocyte contractility increased in a dose-dependent manner in control myocytes but decreased in CHF myocytes. For example, in the presence of 200 pM ET, velocity of shortening increased by 32.8 +/- 2.3 microns/s in controls but decreased by 8.3 +/- 2.2 microns/s with CHF. LV sarcolemmal ET-receptor density was primarily of the ETA-receptor subtype in controls (96 +/- 1.0%) and was unchanged with CHF. In quiescent myocyte preparations, control myocytes secreted ET (2.29 +/- 0.45 amol.cell-1.h-1), which was similar in CHF myocytes. These findings suggest that the production of ET may have important and potentially differential effects on contractile function with the development of CHF.
First Per-6-<i>O</i>-tritylation of Cyclodextrins (2012)

Because of the large dimension of the trityl group and the truncated conical geometry of cyclodextrin (CD) molecules, it is unclear if there is enough space at the narrower end of CDs to permit a per-6-O-tritylation. This work demonstrates that it is indeed possible to simultaneously install a trityl group at the O6-position of every glucopyranosyl unit in a CD. A novel per-6-substitution method has been developed for CD chemistry.
[Validation of electronic by conventional pain diaries]. (1991)

A new type of electronic pain diary was validated in an open, randomized, crossover study. The main target variables were the comparison of the correctly realized pain assessment entries as well as the recording of the number of adverse events. Selected for the study were 20 patients, who were either hospitalized, partially-hospitalized or treated on an out-patient basis, with painful spondylogenic spinal syndrome or osteoarthritis of the trunk-proximal large joints. The patients were randomly-assigned to the two groups. The first group initially received the conventional diary and thereafter the electronic diary; the sequence was reversed for the second group. The drug therapy consisted of the NSAID, Ibuprofen, at an individually-adjusted dosage. Additional therapeutic measures were carried out by all the patients. The electronic pain diary proved to be equivalent to the conventional diary with regard to adherence of the pain assessment entry times. At a defined equivalence range of +/- 20%, the statistical comparison showed that the limits were never exceeded. The equivalence test of Anderson-Hauck showed a significance level of p less than 0.0001. The minimum equivalence range was +/- 2%. It therefore follows, that the conventional method of data recording can indeed be fully replaced by the electronic method. Comparing the individual data of the 16 patients, from whom entries with both the electronic as well as the conventional pain diaries were submitted, a clear tendency for increased entries on adverse events in the electronic diary (C.D. 6.4 +/- 10.5/E.D. 36.4 +/- 44.1) was demonstrated. No significant difference, however, was shown for the number of patients making data entries on adverse events in the electronic pain diary compared to those patients, who made their entries on adverse events in the conventional diary. According to the data from the physicians and patients, the Ibuprofen treatment results in an improvement in 90%/75% of cases, respectively. Likewise, the functional impairment of the affected joints as well as the swelling decreased markedly. The advantages of the electronic data recording system, i.e. closely-meshed controls can be carried out, transcriptional errors are minimized, data can be processed on-line, no possibility to subsequently change an entry, stand in contrast to the feature that there is no possibility to make free-style entries. The employment of the electronic system in the recording of individual data and subjective data represents a substantial improvement with regard to the quantity and quality of the data.
NOVEL LEADFRAME-BASED PACKAGE PROVIDES PERFORMANCE BOOST FOR HARD DISK DRIVE DATA TRANSFER PERFORMANCE (2008)

Increased storage densities and faster data transfer rates in Hard Disk Drive (HDD) applications require improved electrical and thermal characteristics within associated semiconductor packaging. A case study of a new IC packaging technology termed “FusionQuad” is presented. Effectively, FusionQuad represents the integration of QFN and TQFP technologies, providing exceptional electrical and thermal performance in a cost-effective leadframe-based package. FusionQuad also doubles external inputs and outputs (I/O) for a given leadframe package body size by eliminating the historical barrier of only peripheral leads. Electrical and thermal performance comparisons with an exposed pad TQFP (TQFP) for HDD applications are presented. Board level mounting and reliability results are also reviewed.
Five-year follow-up study of tardive dyskinesia. (1985)

A 5-year follow-up investigation of TD was carried out in 85 Hungarian schizophrenic out-patients. No substantial changes occurred during the 5 years in pharmacotherapy: most patients continued on neuroleptics and antiparkinson drugs. Comparison of 1978 and 1983 ratings revealed increased dyskinesia scores, which was statistically significant on the DRS Choreo-athetosis cluster. There was an increase in the number of patients with "moderately" severe TD from 4 in 1978 to 6 in 1981 to 10 (9 "Moderate" and 1 "Severe" TD) in 1983. The total number of TD cases as defined by research diagnostic criteria increased by only 3. The long-term trend in these neuroleptic-treated schizophrenics is for dyskinesia to plateau after reaching mild intensity, while in a minority of cases, the dyskinesia tends to extend from the oro-facial region to other body regions.
Aeroelastically Tailored Propellers (1977)

<div class="htmlview paragraph">An analytical investigation into the possible improvement of aircraft propeller performance that may be obtained by employing high strength filamentary composite materials to modify the elastic characteristics of the blades was conducted. The orientation of the individual fibers with respect to the axis of the blade was chosen to induce a coupling between the centrifugal force acting on the blade and the shearing strain in the plane of the blade cross section. The shearing strain changes the pitch of the blade as the rotational speed of the propeller is varied. This change in pitch is then optimized to broaden the band of flight speeds over which the propeller operates efficiently.</div> <div class="htmlview paragraph">Results for the analytical model indicate that the efficiency of non-controllable pitch propellers may be improved by 5% at the design condition and as much as 20% at off-design conditions. Furthermore, the results indicate a significant increase in the band of flight speeds over which the propeller operates efficiently. In addition, a 5% increase in efficiency throughout the applicable range of flight conditions was determined for controllable pitch propellers employing composite blades in place of rigid blades.</div>
Implementation and evaluation of practice guidelines. (1993)

Practice guidelines for the management of deep vein thrombosis were implemented in a Problem-Oriented Patient Management System on the HELP Hospital Information System at the LDS Hospital. A hierarchical knowledge representation was used. The Problem-Oriented Patient Management System was designed to generate patient-specific guideline suggestions according to the clinical situation at the time of generation. A retrospective evaluation was used to compare the appropriateness of the generated guideline suggestions to the appropriateness of the attending physician's management decisions. A significantly higher proportion of guideline suggestions was evaluated to be appropriate, compared to the proportion of attending physician's management decisions found to be appropriate.
Advances in lock-in amplifiers (1982)

The key specification points of lock-in amplifier systems for signal recovery and signal characteristics are reviewed and it is shown how these can be improved and modified by more advanced system design. The configurations of several commercially available systems are described and the facilities available in computer-controlled lock-in systems are discussed briefly, together with some new application areas.
Homeohydrous (Recalcitrant) Seeds: Dehydration, the State of Water and Viability Characteristics in <i>Landolphia kirkii</i> (1991)

Differential scanning calorimetry was used to study the relationships among drying rate, desiccation sensitivity, and the properties of water in homeohydrous (recalcitrant) seeds of Landolphia kirkii. Slow drying of intact seeds to axis moisture contents of approximately 0.9 to 0.7 gram/gram caused lethal damage, whereas very rapid (flash) drying of excised embryonic axes permitted removal of water to approximately 0.3 gram/gram. The amount of nonfreezable water in embryonic axes (0.28 gram H(2)O/gram dry mass) did not change with drying rate and was similar to that of desiccation-tolerant seeds. These results suggest that the amount of nonfreezable water per se is not an important factor in desiccation sensitivity. However, flash drying that removed all freezable water damaged embryonic axes. Differences between desiccation-sensitive and -tolerant seeds occur at two levels: (a) tolerant seeds naturally lose freezable water, and sensitive seeds can lose this water without obvious damage only if it is removed very rapidly; (b) tolerant seeds can withstand the loss of a substantial proportion of nonfreezable water, whereas sensitive seeds are damaged if nonfreezable water is removed.

Hardware Accelerated Displacement Mapping for Image Based Rendering (2001)

In this paper, we present a technique for rendering displacement mapped geometry using current graphics hardware. Our method renders a displacement by slicing through the enclosing volume. The alpha-test is used to render only the appropriate parts of every slice. The slices need not to be aligned with the base surface, e.g. it is possible to do screen-space aligned slicing. We then extend the method to be able to render the intersection between several displacement mapped polygons. This is used to render a new kind of image-based objects based on images with depth, which we call image based depth objects. This technique can also directly be used to accelerate the rendering of objects using the image-based visual hull. Other warping based IBR techniques can be accelerated in a similar manner.
