Osiris: A Low-Cost Mechanism to Enable Restoration of Secure Non-Volatile Memories (2018)

With Non-Volatile Memories (NVMs) beginning to enter the mainstream computing market, it is time to consider how to secure NVM-equipped computing systems. Recent Meltdown and Spectre attacks are evidence that security must be intrinsic to computing systems and not added as an afterthought. Processor vendors are taking the first steps and are beginning to build security primitives into commodity processors. One security primitive that is associated with the use of emerging NVMs is memory encryption. Memory encryption, while necessary, is very challenging when used with NVMs because it exacerbates the write endurance problem. Secure architectures use cryptographic metadata that must be persisted and restored to allow secure recovery of data in the event of power-loss. Specifically, encryption counters must be persistent to enable secure and functional recovery of an interrupted system. However, the cost of ensuring and maintaining persistence for these counters can be significant. In this paper, we propose a novel scheme to maintain encryption counters without the need for frequent updates. Our new memory controller design, Osiris, repurposes memory Error-Correction Codes (ECCs) to enable fast restoration and recovery of encryption counters. To evaluate our design, we use Gem5 to run eight memory-intensive workloads selected from SPEC2006 and U.S. Department of Energy (DoE) proxy applications. Compared to a write-through counter-cache scheme, on average, Osiris can reduce 48.7% of the memory writes (increase lifetime by 1.95x), and reduce the performance overhead from 51.5% (for write-through) to only 5.8%. Furthermore, without the need for backup battery or extra power-supply hold-up time, Osiris performs better than a battery-backed write-back (5.8% vs. 6.6% overhead) and has less write-traffic (2.6% vs. 5.9% overhead).
A logic for handling time in temporal databases (2003)

An approach to the handling of time in query languages of historical database management systems is outlined. The approach is based on extending Boolean and comparison operators by allowing their operands to be sets of time intervals. The proposed temporal logic is shown to satisfy the properties of the normal Boolean logic. A relational-calculus query language using the extended logic is proposed. A new syntax for retrieval statements is defined in order to separate the process of selecting entities (tuples) and the process of selecting required values of temporal attributes from the chosen entities. The extension presented in this paper offer a good degree of flexibility in expressing different temporal requirements.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A magnetic-particles display (1975)

A new type of flat-panel ambient-illuminated display is described. Images in this display are formed by magnetically controlling the orientations of small spherical multicolored magnetic particles. A demonstration model is shown and the possibility for application to television is studied. It is estimated that for a 9 × 12-cm black-and-white screen with built-in magnetic memory and 500 × 500 sequential matrix addressing the display panel can be driven at TV rates with an average current of 0.27 A and dissipation of 0.26 W. Contrast ratios up to 40:1 seem achievable with continuously variable grays. The display also features a nonvolatile memory which can be very desirable for some applications. Methods for fabricating this display are also discussed.
CrossSketch (2007)

This paper presents a novel technique to model a three dimensional freeform surface, in its global shape and small details, using a sketching interface, from a single point of view. In the past, most modeling systems that used sketches as input reconstructed the shape from the silhouette, and the user had few control on the inner parts of the result. In our system, we generate a grid of co-planar lines from a small number of strokes that the user drew, then we estimate the normal vector where it is constrained, and we form the surface by propagating this information to the whole grid. As a result, smaller strokes act locally to add detail, while longer strokes modify the whole surface. Our system gives a new approach to the modeling from sketches problem, and is intended to be a part of a more complex modeling system.
Analysis of immunoregulatory pathways in murine pregnancy (1985)

Understanding how the antigenically foreign fetus escapes attack by maternal lymphoid cells has long been a goal of reproductive immunologists. The present thesis work analyzes the expression and regulation of maternal immunity to self Ia antigen, as well as to embryonic antigens common to fetal and tumor cells but absent from normal adult somatic tissues. Initial studies revealed that the in vitro proliferative capacity of thymus and bone marrow-derived T cells is enhanced during syngeneic murine pregnancy. Pregnancy was also found to promote the manifestation of autoreactive splenic T cells capable of mediating syngeneic graft-versus-host reactions. In addition, primigravid isopregnant mice harbour splenic T cells which are specifically sensitized to syngeneic fetal antigens. Both alpha-fetoprotein and a population of B-like pregnancy-associated splenic suppressor cells were shown to be potent regulators of autoimmune lymphoproliferative activity. Monoclonal antibodies (clone PSBA-1) were generated which, in the presence and absence of complement, abrogate the in vitro inhibitory activity of such suppressor cells. Moreover, a significant proportion of gravid females which were treated with PSBA-1 antibodies resorbed their embryos. Thus, a B-like suppressor cell appears to play a crucial immunoregulatory role during murine pregnancy.
An envelope delay-measuring instrument in the audio-frequency range (1956)

IT HAS long been recognized that careful attention must be given to the amplitude response of all types of communication systems throughout the useful frequency range. Other effects arising from system phase characteristics became evident as circuit lengths increased. These effects, resulting from phase distortion, persisted even after perfect correction had been made for amplitude distortion. In telephony for relatively short distances, phase distortion was usually of small importance. However, with the increased length of circuits phase distortion over the essential range of frequencies was found to play an important role. In landline code telegraphy, d-c or carrier, the effects of phase response are negligible compared with amplitude response. In any event, the processes of signal regeneration, sampling, or pickup, and code translation provide a “margin” within which distortion effects are absent and a perfect printed reproduction of the telegraph message is obtained.
Exploitation of Semantic Web Technology in ERP Systems (2007)

Until recently existing technologies enabling the integration of enterprise systems, use very few of the capabilities of modern research. For example, the activity of finding services, which should deliver expected enterprise functionality, has to be driven by humans. The process of assembling pieces of functionality into complex business processes also involves human interaction. The semantic web technology can be used in the context of an ERP to enable the lacking automation process. This technology can significantly contribute to overcome the deficiencies rooting from the heterogeneity of information contents and semantics generated from various sources. A challenge in Enterprise Information System is the detailed capture of activities and process information. The semantic integration of Personal Information Management Systems could be regarded as a first step towards the modernization of ERP applications. We also describe the opportunities of significantly improving business security by using ontologies. The use of ontology concepts of the Semantic Web can be regarded as an essential step in the evolution of Service Oriented Architectures for ERP applications.

Reversible Immunocontraception in Male Monkeys Immunized with Eppin (2004)

Various forms of birth control have been developed for women; however, there are currently few options for men. The development of male contraceptives that are effective, safe, and reversible is desired for family planning throughout the world. We now report contraception of male nonhuman primates (Macaca radiata) immunized with Eppin, a testis/epididymis-specific protein. Seven out of nine males (78%) developed high titers to Eppin, and all of these high-titer monkeys were infertile. Five out of seven (71%) high-anti-Eppin titer males recovered fertility when immunization was stopped. This study demonstrates that effective and reversible male immunocontraception is an attainable goal. This method of immunocontraception may be extended to humans.
High-intensity focused ultrasound (HIFU) multiple lesion imaging: comparison of detection algorithms for real-time treatment control (2003)

Imaging of HIFU-induced lesions provides non-invasive, real-time treatment monitoring and control. This work presents results obtained with HIFU-induced lesion detection algorithms specifically designed for multiple lesion detection. Algorithms sensitive to relative tissue changes during HIFU -measuring signal energy, tissue displacement, entropy, and tissue attenuation are compared for their ability to detect the creation of multiple and adjacent HIFU lesions. In vivo (N=4) canine prostate backscattered RF data was acquired with a custom Sonablate/spl reg/500 HIFU device during 7 treatments. A total of 815 sites were treated, forming the algorithm evaluation dataset. It was found that the algorithm based on signal energy performed best, detecting 82% of all HIFU lesions created, while showing false-alarm rates below 5%. All methods are completely non-invasive, and make use of tissue reference/normalization information obtained before, during, and after the HIFU treatment. Algorithm specifics, data acquisition methodologies, in vivo experimental results, and algorithm comparison results are shown.
High Durability of Carbon Nanotube-Supported Pt Electrocatalysts Covered with Silica Layers for the Cathode in a PEMFC (2008)

Multiwalled carbon nanotube (CNT)-supported Pt nanoparticles (Pt/CNT) were covered with silica layers by successive hydrolysis of 3-aminopropyl-triethoxysilane and tetraethoxysilane on CNTs with Pt metal precursors, followed by reduction with hydrogen. The Pt/CNT covered with silica layers was used as a cathode catalyst for a proton exchange membrane fuel cell (PEMFC). The activity of catalyst for the oxygen reduction reaction in a single-cell PEMFC was similar to that of Pt/CNT, in spite of the uniform coverage of Pt with silica layers, indicating that the coverage of Pt/CNT with silica layers did not appreciably decrease the catalytic activity. In addition, electrocatalyst showed high stability during potential cycling from 0.05 to vs reversible hydrogen electrode in an aqueous electrolyte, whereas Pt/CNT significantly deactivated during the experiment. The structural change of Pt species in these electrocatalysts during potential cycling was investigated by transmission electron microscopy images and -edge X-ray absorption fine structure. The crystallite size of Pt metal in did not change appreciably during the potential cycling, while Pt metal crystallites in Pt/CNT seriously aggregated. Silica layers enveloping Pt metal particles in prevent the dissolution and redeposition of Pt metal particles as well as the agglomeration of Pt metal particles on the supports.
HP‐RAFT: A Free‐Radical Polymerization Technique for Obtaining Living Polymers of Ultrahigh Molecular Weights (2004)

Poly(methyl methacrylate)s of extremely high molecular weights (>106) and narrow molecular weight distributions (M̄w/M̄n<1.2:1) were easily obtained by living/controlled free-radical polymerization under high hydrostatic pressure (5 kbar; see scheme, AIBN=2,2′-azobis(isobutyronitrile)). This technique provides conditions amenable to industrial scale-up.

Stem cell therapy for myocardial regeneration: creating hype ignoring reality (2005)

I read with interest the recent article in European Journal of Cardio-Thoracic Surgery by Siepe and colleagues [1] where they have reviewed the work done in the field of stem cell research for myocardial regeneration. It is an excellent review paper. I would like to add a few points which unfortunately have not been addressed in this article. Despite significant advances in medical and surgical management of heart failure, the mortality and morbidity associated with it continues to be high. Cardiomyocyte apoptosis (programmed cell death) has been implicated in the development of end-stage heart failure [2]. Myocardial regeneration will be the ideal treatment for these failing hearts. It explains the hype created around cellular therapy, more appropriately called ‘Cellular Cardiomyoplasty’ by many investigators. In fact, while this issue is getting debated, some centres in South East Asian countries have started charging fees from patients for treatment with coronary artery bypass grafting and stem cell therapy as single procedure. It means not only are we stretching things too far but also the fact that it constitutes unethical practice. The evidence in support of stem cell therapy as means for myocardial regeneration is not flawless, to say the least. We do not know which cell type to inject; how to inject (delivery of cells); where to inject (centre of the scar vs periphery of scar); when to inject (immediately after myocardial infarction vs delayed injection); how much to inject (dosing) and safety, efficacy and long-term results. Recently the critical question of host immune response to implanted cells has started to receive attention from the researchers [3]. Recent studies on immune interactions of bone marrow mesenchymal stem cells have raised doubts over the concept of myocardial regeneration leading to functional recovery. Do they really form new functioning cardiomyocytes or is the improvement in ventricular function cytokine/chemokines mediated [4]? Very few engrafted cells express specific cardiac markers like connexion 43 and cardiac troponin I and only limited gap junctions are formed between grafted and native cells [4]. Even if they form new cardiomyocytes, the question of proper integration and communication with the host tissues remains unanswered.
Control of crisis-induced intermittency in the dynamics of a kicked, damped spin (1997)

A method of controlling the intermittent behavior induced by a crisis is applied to a model of a periodically kicked, damped spin. Using small, occasional changes of a parameter, one can make the system remain on a former attractor, enlarged or destroyed by a crisis. The amplitude of the changes grows linearly with the distance from the crisis point, and the frequency of interventions scales as the inverse of the characteristic time of the intermittency.
The role of mass spectrometry in vitamin D research (1995)

Abstract 1,25‐dihydroxyvitamin D 3 is the active metabolite of vitamin D 3 , and has been found to play important roles in mineral balance and immunological regulation. Recently, 1,25‐dihydroxyvitamin D 3 and similar synthetic analogs in development have been found to possess potential therapeutic values in the treatment of proliferative diseases, including leukemia, breast cancer, and psoriasis. Current methods for the analysis of these compounds may either lack the necessary sensitivity (i.e., UV detection) or specificity (i.e., receptor binding assay). In addition, the synthetic analogs developed to date have not been found to uniformly bind with receptors in binding assays, a property that may render them to be difficult for measurement at the trace levels. Methods utilizing mass spectrometry (MS) have been used for either structural identification or quantification. Electron impact ionization has been the technique of choice for structural analysis, whereas newer ionization techniques have been utilized for the quantification of metabolites, often in conjunction with on‐line separation. In this review, MS and non‐MS based methods for vitamin D analysis will be discussed, with an emphasis on the former. Historical perspectives, the present state, and the future role of MS in vitamin D research will be discussed. © 1996 John Wiley & Sons, Inc.

Static and dynamic properties of magnetic nanowires in nematic fluids (invited) (2005)

Microscopy experiments are employed to characterize the elastic interactions of magnetic nickel nanowires suspended in a nematic liquid crystal. The nematic imposes a torque on an isolated wire that increases linearly with the angle between the wire and the nematic director in a manner quantitatively consistent with predictions based on an analogy between the nematic elasticity and electrostatics. An extension of this analogy also explains a measured orientation-dependent repulsive force between a wire and a wall. The angular relaxation of a wire in response to the elastic torque displays a nonexponential time dependence from which effective viscosities for the fluid are determined. The behavior of a wire in a twisted nematic cell further demonstrates how spatial variations in the director can convert the torque to a controlled translational force that levitates a wire to a specified height.
Design of self-biased coplanar circulator with ferromagnetic nanowires (2018)

A triangular Y-j unction coplanar circulator based on Co nanowire array is designed and simulated in HFSS. Co nanowire array is modelled as ferrite with properties extracted from vibrating sample magnetometer (VSM) and ferromagnetic resonance (FMR) measurement. The circulator consists of printed circuit on Duroid board and nanowire array placed on top of the Y-junction. The simulation results show that with proper estimation of magnetic properties, a circulator can be achieved with 30.9 dB isolation, 2.1 dB insertion loss and 15 dB bandwidth of 1.7 GHz at 28.7 GHz.

Short-Duration Low-Direct-Current Electrical Field Treatment Is a Practical Tool for Considerably Reducing Counts of Gram-Negative Bacteria Entrapped in Gel Beads (2004)

Application of a direct-current electrical field for very short times can serve as a practical nonthermal procedure to reduce or modify the microbial distribution in gel beads. The viability of Escherichia coli and Serratia marcescens entrapped in alginate and agarose beads decreases as the field intensity and duration of electrical field increase.
