Towards a Formal Definition of a Computing Cloud (2010)

Cloud computing has been endorsed by the IT community as the new paradigm shift in the industry that charts the way forward. Unfortunately, the field is still on its path to rigor and robustness. This is epitomized by the numerous fuzzy articulations of “what is cloud computing”. This paper makes a first attempt at remedying this conundrum by providing a core technical specification of the model for cloud computing and demonstrating how current and future cloud deployments can use this to foster more productive technical discussion in future.
A Survey on Control Configuration Selection and New Challenges in Relation to Wireless Sensor and Actuator Networks (2017)

The CCS problem is discussed, and a set of desirable properties of a CCS method are defined. Open questions and research tracks are discussed, with the focus on new challenges in relation to the emerging area of Wireless Sensors and Actuator Networks.
On Spectral Analysis of Heart Rate Variability during Very Slow Yogic Breathing (2005)

Very slow yogic breathing techniques provide valuable insights into mechanisms of autonomous nervous system regulation that are usually not available for human subjects. This paper presents results of eight sessions of Nadi Shodhana Pranayama practiced at rate of one breath per minute. We characterized statistic and spectral measures of heart rate variability before, during, and after exercises. Significant changes include increase of VLF frequencies caused by slow breathing and decrease in average interbeat interval from 959.3 to 904.1 ms (t(7) = -7.5, p<0.001). We present the results of HRV analysis and analyze origins of characteristic frequency components. The most prominent changes of the exercise include significant increase of respiratory sinus arrhythmia (RSA) and LF/HF ratio, and decrease of breathing frequency after the exercise against the state before the exercise. The maximum LF frequency decreased from 0.0919 Hz to 0.07125 Hz (t(7) = -3.255, p < 0.01), indicating the decrease of average breathing rhythm from 5.5 breaths/min to 4.3 breaths/min. In addition, the state after the exercise is characterized by disappearance of VLF frequencies from the spectrum, and a significant increase of LF/HF from 14.33 to 50.93 (t(7) = 2.461, p <.05).
Novel Steroid Inhibitors of Glucose 6-Phosphate Dehydrogenase (2012)

Novel derivatives of the steroid DHEA 1, a known uncompetitive inhibitor of G6PD, were designed, synthesized, and tested for their ability to inhibit this dehydrogenase enzyme. Several compounds with approximately 10-fold improved potency in an enzyme assay were identified, and this improved activity translated to efficacy in a cellular assay. The SAR for steroid inhibition of G6PD has been substantially developed; the 3β-alcohol can be replaced with 3β-H-bond donors such as sulfamide, sulfonamide, urea, and carbamate. Improved potency was achieved by replacing the androstane nucleus with a pregnane nucleus, provided a ketone at C-20 is present. For pregnan-20-ones incorporation of a 21-hydroxyl group is often beneficial. The novel compounds generally have good physicochemical properties and satisfactory in vitro DMPK parameters. These derivatives may be useful for examining the role of G6PD inhibition in cells and will assist the future design of more potent steroid inhibitors with potential therapeutic utility.
Single Crystal Structure of Zeolite A (LTA) Containing Ag4Cl4Nanoclusters and Reduced 1,3,5-Tripyrylium Dimers with Remarkably Short 2.43 Å Interplanar Spacings (2008)

A single crystal of Ag 12−A (zeolite LTA) was prepared by the dynamic ion-exchange of Na 12−A with aqueous 0.05 M AgNO 3. It was washed with CH 3OH and allowed to react with a stream of 0.05 M KCl in CH 3OH at 294 K. The crystal structure of the product |K 2.35Ag 1.1(Ag 4Cl 4) 0.45(C 3H 3O 3) 1.1(K 3Cl) 3.45(K 3(OH) 2) 0.55(H 2O) ≥3.0|[Si 12Al 12O 48]− LTA ( a = 12.292(1) Å) was determined by single-crystal X-ray diffraction in the cubic space group Pm3̅ m at 294 K. It was refined to the final error index, R 1 = 0.052, based on the 371 reflections for which F o > 4σ( F o). Ag 4Cl 4 nanoclusters were found in about 45% of the sodalite cavities. Each Ag 4Cl 4 cluster (interpenetrating tetrahedra; symmetry T d, Ag−Cl = 3.105(17) Å) is held in place by the coordination of each of its four Ag + ions to three oxygens of the zeolite framework (Ag−O = 2.493(5) Å) and by the coordination of each of its four Cl − ions to a K + ion through a 6-ring (Cl−K = 2.70(3) Å). In each of the remaining 55% of the sodalite cavities, two reduced planar 1,3,5-tripyrylium cations, [(CH) 3O 3] 2 2+ (C−O = 1.52(3) Å), are found. These parallel eclipsed rings (symmetry D 3d) have an interplanar distance of only 2.43 Å due to σ double bonding between the rings, the result of four electrons in 12-center bonding π* orbitals, and to polar attraction. Each ring makes three strong hydrogen bonds (CH···O = 2.84(3) Å) to oxygens of the zeolite framework, and a Ag + ion coordinates to the three oxygens of one ring (Ag−O = 2.68(9) Å). The large cavities are filled with K +, Cl −, Ag +, OH −, and H 2O; the K 3Cl 2+ unit predominates. The 1,3,5-tripyrylium ring, isoelectronic with benzene, had not been reported before.
Selected Contribution: Effects of spaceflight on immunity in the C57BL/6 mouse. II. Activation, cytokines, erythrocytes, and platelets (2003)

This portion of the study quantified the effects of a 12-day space shuttle mission (Space Transport System-108/UF-1) on body and lymphoid organ masses, activation marker expression, cytokine secretion, and erythrocyte and thrombocyte characteristics in C57BL/6 mice. Animals in flight (Flt group) had 10-12% lower body mass compared with ground controls housed either in animal enclosure modules or under standard vivarium conditions (P < 0.001) and the smallest thymus and spleen masses. Percentages of CD25(+) lymphocytes, CD3(+)/CD25(+) T cells, and NK1.1(+)/CD25(+) natural killer cells from Flt mice were higher compared with both controls (P < 0.05). In contrast, CD71 expression was depressed in the Flt and animal enclosure module control mice compared with vivarium control animals (P < 0.001). Secretion of interferon-gamma, IL-2, and IL-4, but not tumor necrosis factor-alpha and IL-5, by splenocytes from Flt mice was decreased relative to either one or both ground controls (P < 0.05). Flt mice also had high red blood cell and thrombocyte counts compared with both sets of controls; low red blood cell volume and distribution width, percentage of reticulocytes, and platelet volume were also noted (P < 0.05) and were consistent with dehydration. These data indicate that relatively short exposure to the spaceflight environment can induce profound changes that may become significant during long-term space missions.
Telomerase-Associated Protein TEP1 Is Not Essential for Telomerase Activity or Telomere Length Maintenance In Vivo (2020)

TEP1 is a mammalian telomerase-associated protein with similarity to the Tetrahymena telomerase protein p80. Like p80, TEP1 is associated with telomerase activity and the telomerase reverse transcriptase, and it specifically interacts with the telomerase RNA. To determine the role of mTep1 in telomerase function in vivo, we generated mouse embryonic stem (ES) cells and mice lacking mTep1. The mTep1-deficient (mTep1−/−) mice were viable and were bred for seven successive generations with no obvious phenotypic abnormalities. All murine tissues from mTep1−/− mice possessed a level of telomerase activity comparable to that in wild-type mice. In addition, analysis of several tissues that normally lack telomerase activity revealed no reactivation of telomerase activity in mTep1−/− mice. Telomere length, even in later generations of mTep1−/− mice, was equivalent to that in wild-type animals. ES cells deficient in mTep1 also showed no detectable alteration in telomerase activity or telomere length with increased passage in culture. Thus, mTep1 appears to be completely dispensable for telomerase function in vivo. Recently, TEP1 has been identified within a second ribonucleoprotein (RNP) complex, the vault particle. TEP1 can also specifically bind to a small RNA, vRNA, which is associated with the vault particle and is unrelated in sequence to mammalian telomerase RNA. These results reveal that TEP1 is an RNA binding protein that is not restricted to the telomerase complex and that TEP1 plays a redundant role in the assembly or localization of the telomerase RNP in vivo.
Revealing SRAM memory content using spontaneous photon emission (2016)

This paper presents a novel methodology that allows one to reveal SRAM memory content by observing the spontaneous photon emission collected from the backside of the chip. This method is based on our proposed tester-based optical methodology [1] that combines different test patterns, time-integrated and time-resolved emission measurements to localize gates, detect logic states, and identify functional block activity inside a chip in a non-invasive fashion. In this paper, the capability of the technique is demonstrated using a 64 Mb SRAM test chip fabricated in 14 nm SOI technology node. This technique has useful applications for chip debugging, reverse engineering, hardware and software security applications.
Systematic comparison of respiratory syncytial virus-induced memory B cell responses in two anatomical compartments (2019)

Respiratory syncytial virus (RSV) is a leading cause of hospitalization in infants and young children. Although it is widely agreed that an RSV vaccine should induce both mucosal and systemic antibody responses, little is known about the B cell response to RSV in mucosa-associated lymphoid tissues. Here, we analyze this response by isolating 806 RSV F-specific antibodies from paired adenoid and peripheral blood samples from 4 young children. Overall, the adenoid-derived antibodies show higher binding affinities and neutralization potencies compared to antibodies isolated from peripheral blood. Approximately 25% of the neutralizing antibodies isolated from adenoids originate from a unique population of IgM<sup>+</sup> and/or IgD<sup>+</sup> memory B cells that contain a high load of somatic mutations but lack expression of classical memory B cell markers. Altogether, the results provide insight into the local B cell response to RSV and have implications for the development of vaccines that stimulate potent mucosal responses.
Mesoporous ZSM-5 Zeolite-Supported Ru Nanoparticles as Highly Efficient Catalysts for Upgrading Phenolic Biomolecules (2015)

Zeolite-based catalysts have been widely used in the conversion of biomass recently, but the catalytic yields of the desired products are strongly limited by the relatively small micropores of zeolite. Here, we reported a hierarchically porous ZSM-5 zeolite with micropore and b-axis-aligned mesopore-supported Ru nanoparticles (Ru/HZSM-5-OM) that are highly efficient for the hydrodeoxygenation of both small and bulky phenolic biomolecules to the corresponding alkanes. Compared with the conventional ZSM-5 zeolite-supported Ru catalyst, the high catalytic activities and alkane selectivities over Ru/HZSM-5-OM are attributed to the abundant exposed acidic sites in HZSM-5-OM with open mesopores. This feature is potentially important for future phenolic bio-oil upgrading.
POSTER (2014)

Over the past few years, Proximity-based People Discovery (PBPD) services, typically known as Nearby Friends,have been increasingly popular among geosocial apps. Unlike many unsuccessful predecessors which directly pinpoint users' exact locations on the map, PBPD services provide coarse-grained (discretized) proximity information, such as "Jennifer is within 2 miles," striking a useful balance between privacy and functionality. Considering PBPD's business potential, many companies including Facebook have been trying to promote this feature and instill the perception in mobile users that coarse-grained proximity information is innocuous to share. Here, we propose a novel positioning attack which can locate end-users of PBPD services with high precision using only coarse-grained (discretized) proximity information. This attack requires neither specialized hardware nor server-side collusion and can be easily automated. Based on this attack, we design and implement Geosocial Positioning System (GsPS) and show that GsPS can effectively locate users with high precision (10m) in a matter of a few minutes under real-world settings, and is capable of performing effective city-scale scanning and long-term profiling at low costs. The public and the social network industry should therefore be aware of the potential risk introduced by this attack and consider use of PBPD services with caution.
Sclera Force Control in Robot-assisted Eye Surgery: Adaptive Force\n Control vs. Auditory Feedback (2019)

Surgeon hand tremor limits human capability during microsurgical procedures\nsuch as those that treat the eye. In contrast, elimination of hand tremor\nthrough the introduction of microsurgical robots diminishes the surgeon's\ntactile perception of useful and familiar tool-to-sclera forces. While the\nlarge mass and inertia of eye surgical robot prevents surgeon microtremor, loss\nof perception of small scleral forces may put the sclera at risk of injury. In\nthis paper, we have applied and compared two different methods to assure the\nsafety of sclera tissue during robot-assisted eye surgery. In the active\ncontrol method, an adaptive force control strategy is implemented on the\nSteady-Hand Eye Robot in order to control the magnitude of scleral forces when\nthey exceed safe boundaries. This autonomous force compensation is then\ncompared to a passive force control method in which the surgeon performs manual\nadjustments in response to the provided audio feedback proportional to the\nmagnitude of sclera force. A pilot study with three users indicate that the\nactive control method is potentially more efficient.\n
Predictive current control in a single phase PFC boost rectifier (2009)

Predictive control has become a promising alternative to control power electronics devices, due to the continuous development of digital processing technologies. Predictive control methods exhibit high dynamic response being well suited to system that require tracking capabilities. In this paper a power factor correction rectifier, that requires a current control with a rectified sinusoidal reference, is controlled using three methods: i) Linear control ii) Hysteresis control iii) Predictive control. All these controllers are implemented on a digital platform. Simulation results show that predictive control offers a valid alternative to the others proposed control methods in terms of input current harmonic content and input power factor.
Measurements of extremely low frequency signals from modulation of the polar electrojet above Fairbanks, Alaska (1989)

The high-power auroral stimulation (HIPAS) ionospheric heater facility located 50 km east of Fairbanks, Alaska, has recently been made operational and available to the scientific community. Observations of extremely-low-frequency (ELF) signals generated using the HIPAS ionospheric heater are presented. These observations were the first to be made with this facility and help to demonstrate its early success. During the period of June 10-June 25, 1987, extensive experiments were performed to evaluate the scope of applications for studying the high-latitude ionosphere and the polar electrojet current system. Results of ELF stepped-frequency, polarization, and beam-steering experiments are described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Differential Seroprevalence of Human Bocavirus Species 1-4 in Beijing, China (2012)

Our data indicate that HBoV1 is more prevalent than HBoV2, HBoV3, and HBoV4 in the population we sampled in Beijing, China, suggesting that HBoV species may play differential roles in disease.
Illumination Invariant Foreground Object Segmentation using ForeGANs (2019)

The foreground segmentation algorithms suffer performance degradation in the presence of various challenges such as dynamic backgrounds, and various illumination conditions. To handle these challenges, we present a foreground segmentation method, based on generative adversarial network (GAN). We aim to segment foreground objects in the presence of two aforementioned major challenges in background scenes in real environments. To address this problem, our presented GAN model is trained on background image samples with dynamic changes, after that for testing the GAN model has to generate the same background sample as test sample with similar conditions via back-propagation technique. The generated background sample is then subtracted from the given test sample to segment foreground objects. The comparison of our proposed method with five state-of-the-art methods highlights the strength of our algorithm for foreground segmentation in the presence of challenging dynamic background scenario.

Comparison of Particulate Dose from Exposure to Environmental Tobacco Smoke (ETS) and Mainstream Cigarette Smoke Using Radiotracers (1997)

There has been considerable debate in recent years regarding the health risks resulting from exposure to environmental tobacco smoke (ETS). To date, there has been no direct method of measuring the amount and distribution of tar particulate from ETS deposited in the respiratory tract, or for estimating subsequent clearance. Indeed only one study by Hiller et al. (1982) has reported an ETS deposition fraction of 11 ± 4% in a group of five volunteers. It remains difficult to find representative chemical markers of the ETS particulate aerosol in environmental situations, as many have a significant vapour component on ageing and dilution of the smoke. A I-l-iodohexadecane radiolabel for mainstream smoke (Pritchard et al., 1988; McAughey et al., 1996) was unsuitable for sidestream tobacco smoke as 70% of the label (and particulate mass) evaporated on ageing and dilution (Pritchard et al., 1988b). As an alternative, it is known that the radioactive decay products of the naturally occurring gases Rn (radon) and 220 Rn (thoron) when first formed have a high mobility and easily become attached to particles such as ETS suspended in the atmosphere. The 220 Rn (thoron) series decays via Po to Pb, with a radioactive half-life of 10.6 h (240 keV y-ray emission) which would allow monitoring over an appropriate period.
A digital PUF-based IP protection architecture for network embedded systems (2014)

In this paper we present an architecture for a secure embedded system that is resilient to tempering and code injection attacks and offers anti-piracy protection for the software and hardware Intellectual Property (IP). We incorporate digital Physical Unclonable Functions (PUFs) in an authentication mechanism at the machine code level. The digital PUFs are used to de-obfuscate, at run time, a firmware that's issued by a central authority with very little performance and resource overhead. Each PUF is unique to the hosting device, and at the same time can be reconfigured with new seeds. The reconfigurable digital PUFs (drPUFs) have much lower risks of side-channel attacks and vastly higher number of usable challenge-response pairs, while retaining the speed and ease to implementation of digital PUFs.
SOME HUMORAL EFFECTS IN SIBERIAN STURGEON (ACIPENSER BAERI BRANDT) AFTER LYSOZYME DIMER APPLICATION IN BATH (2000)

ABSTRACT. The present study was undertaken to evaluate humoral indices response in sturgeons reared under controlled conditions and treated with exogenous lysozyme dimer in immersion. Fish of average body weight 40±4 g were bathed for 30 minutes in 0.1 mg l-1 of dimer (Lydium KLP-602). After the treatment, blood was sampled from the fish for 7 weeks, at weekly intervals. Lysozyme activity, the level of -globulins, ceruloplasmin, and total protein were measured in blood serum. Average body weight of fish increased 5 fold (to 210±12 g) during the experiment. In treated fish the bacteridytie activity of endogenous lisozyme, -globulins, and ceruloplasmin levels increased already in the first week after immersion by 27%, 40%, and 60 % respectively. Increase of these parameters was observed until the end of the experiment. The results indicate that lysozyme dimer stimulated humoral responses in fish.
Machining of a bioactive nanocomposite orthopedic fixation device (2012)

Bioactive ceramics bond to bone and enhance bone formation. However, they have poor mechanical properties which restrict their machinability as well as their application as load bearing implants. The goal of this study was to machine bioactive fixation screws using a silica-calcium phosphate nanocomposite (SCPC50). The effect of compact pressure, holding time, and thermal treatment on the microstructure, machinability, and mechanical properties of SCPC50 cylinders were investigated. Samples prepared by powder metallurgy technique at compact pressure range of 100-300 MPa and treated at 900°C/1 h scored a poor machinability rating of (1/5) due to the significant formation of amorphous silicate phase at the grain boundaries. On the other hand, lowering of compact pressure and sintering temperature to 30 MPa/3 h and 700°C/2 h, respectively, minimized the formation of the amorphous phase and raised the machinability rating to (5/5). The modulus of elasticity and ultimate strength of machinable SCPC50 were 10.8 ± 2.0 GPa and 72.8 ± 22.8 MPa, respectively, which are comparable to the corresponding values for adult human cortical bone. qRT-PCR analyses showed that bone cells attached to SCPC50 significantly upregulated osteocalcin mRNA expression as compared to the cells on Ti-6Al-4V. Moreover, cells attached to SCPC50 produced mineralized bone-like tissue within 8 days. On the other hand, cells attached to Ti-6Al-4V failed to produce bone mineral under the same experimental conditions. Results of the study suggest that machinable SCPC50 has the potential to serve as an attractive new material for orthopedic fixation devices.
Stem cells isolated from human dental pulp and amniotic fluid improve skeletal muscle histopathology in mdx/SCID mice (2015)

This study shows that hAFSCs and hDPSCs represent potential sources of stem cells for translational strategies to improve the histopathology and potentially alleviate the muscle weakness in patients with DMD.
<title>Analogue-domain FPN compensation circuit for random access CMOS imagers</title> (1997)

Random access active pixel CMOS image sensors generally suffer from non-uniformity in their pixel outputs. This document describes a simple mixed analogue-digital integrated circuit for fixed-pattern-noise compensation. The method has been applied to the range of sensors developed by IMEC, and improves their operation beyond mere static noise suppression.
