The application of differential privacy for rank aggregation: Privacy and accuracy (2014)

The potential risk of privacy leakage prevents users from sharing their honest opinions on social platforms. This paper addresses the problem of privacy preservation if the query returns the histogram of rankings. The framework of differential privacy is applied to rank aggregation. The error probability of the aggregated ranking is analyzed as a result of noise added in order to achieve differential privacy. Upper bounds on the error rates for any positional ranking rule are derived under the assumption that profiles are uniformly distributed. Simulation results are provided to validate the probabilistic analysis.
Generation of transgenic golden Syrian hamsters (2014)

Golden Syrian hamsters are small rodents, but they display many features that resemble the physiology and metabolism of humans. Hamsters have been widely used in many research areas, including carcinogenesis1, reproduction2, virology3, diabetes4 and cardiovascular diseases5. With respect to lipid and glucose metabolism, hamsters, like humans, exhibit high levels of cholesteryl ester transport protein (CETP), intestinal-only ApoB editing, low levels of hepatic low-density lipoprotein (LDL) receptor activity6 and a high glycemic response to dietary fructose7, all of which are not observed in other rodents such as mice and rats. Consequently, hamsters, like humans, exhibit enhanced susceptibility to atherosclerosis (AS) and diabetes8, which led to the widespread use of hamsters in studies on AS and diabetes.
Rooting of apple stem slices in vitro is affected by indoleacetic-acid depletion of the medium (1997)

We have studied rooting of 1-mm thick apple stem slices in relation to indoleacetic acid (IAA) depletion of the medium. When slices were cultured in the dark close to one another on a 3-mm thick medium (20 ml in a 9-cm Petri dish), the IAA concentration in the medium beneath the slices dropped to 20 % of the initial concentration during the first day of culture. This was due to uptake, enzymatic oxidation and slow replenishment from medium in other areas of the Petri dish. Because of depletion, the rate of IAA uptake decreased with time. When medium was renewed daily, the rate of IAA uptake remained the same. When the slices were cultured scattered over the Petri dish or on a thick layer of medium (6-mm instead of 3-mm thick), they took up more IAA. As could be expected, differences in uptake amongst the various conditions (slices cultured scattered or close to one another; 20 or 40 ml of medium) were small during the first day of culture but large after that. Because the rhizogenic action of IAA occurs not immediately at the start of culture but later (viz., from 24 to 72 h after the start of culture; DE KLERK et al., 1995; J. Exp. Bot. 46, 965-972), rooting at the various conditions corresponded closely to the amount of IAA taken up from 24 to 72h. Since the various incubation conditions resulted in the same maximal root number (but at different IAA concentrations), there was only depletion of the medium with respect to IAA.
Ultra-Low-Power Tuning in Hybrid Barium Titanate–Silicon Nitride Electro-optic Devices on Silicon (2019)

As the optical analogue to integrated electronics, integrated photonics has already found widespread use in data centers in the form of optical interconnects. As global network traffic continues its rapid expansion, the power consumption of such circuits becomes a critical consideration. Electrically tunable devices in photonic integrated circuits contribute significantly to the total power budget, as they traditionally rely on inherently power-consuming phenomena such as the plasma dispersion effect or the thermo-optic effect for operation. Here, we demonstrate ultra-low-power refractive index tuning in a hybrid barium titanate (BTO)-silicon nitride (SiN) platform integrated on silicon. We achieve tuning by exploiting the large electric field-driven Pockels effect in ferroelectric BTO thin films of sub-100 nm thickness. The extrapolated power consumption for tuning a free spectral range (FSR) in racetrack resonator devices is only 106 nW/FSR, several orders of magnitude less than many previous reports. We demonstrate the technological potential of our hybrid BTO-SiN technology by compensating thermally induced refractive index variations over a temperature range of 20 {\deg}C and by using our platform to fabricate tunable multiresonator optical filters. Our hybrid BTO-SiN technology significantly advances the field of ultra-low-power integrated photonic devices and allows for the realization of next-generation efficient photonic circuits for use in a variety of fields, including communications, sensing, and computing.
Serum Potassium and Clinical Outcomes in the Eplerenone Post–Acute Myocardial Infarction Heart Failure Efficacy and Survival Study (EPHESUS) (2008)

Use of selective aldosterone blockade with eplerenone within the dose range of 25 to 50 mg/d in post-acute myocardial infarction patients with heart failure and left ventricular systolic dysfunction who are treated with standard therapy improves outcomes without an excess of risk of hyperkalemia (> or =6.0 mEq/L) when periodic monitoring of serum K(+) is instituted.
Analysis of the immune response to lipopolysaccharide. Existence of an interspecies cross-reactive idiotype associated with anti-lipid A antibodies. (1990)

LPS is the major surface glycolipid on gram-negative bacteria. In this work, we have idiotypically characterized the antibody response against LPS in different species. To do this, we have produced mAb against LPS. Binding of many of these antibodies to LPS could be inhibited by LPS and lipid A, indicating that the monoclonals are specific for lipid A, the toxic moiety of the LPS molecule. One anti-lipid A antibody, IC9, proved protective against gram-negative bacteremia and endotoxic shock in murine protection models. We generated anti-idiotypic antibodies against IC9. The binding of several of these anti-Id to IC9 was specifically inhibited by lipid A. We used these anti-Id to characterize the anti-LPS response, and the results revealed that the IC9 Id is conserved in different species. The importance of an interspecies cross-reactive Id in the response to endotoxin and its relevance in vaccine development for septic shock are discussed.
Compressed Workweek Scheduling With Days Off Consecutivity, Weekend Off Frequency, And Work Stretch Constraints (2006)

This paper presents a three-day workweek scheduling problem with four types of days-off scheduling constraints: (1) out of the four off days given to each employee per week, at least two must be consecutive, (2) two alternative types of constraints are imposed to ensure that employees get a sufficient proportion of weekends off, (3) the maximum work stretch is four consecutive workdays for each employee, and (4) the maximum number of successive weeks with weekend work is specified. A mathematical model of this problem is formulated and efficiently solved by introducing a bound on workforce size. First, the problem structure is used to determine the minimum workforce size. Subsequently, a workforce-size constraint is added to the integer programming model in order to facilitate solution. Finally, multiple-week rotation schedules are produced to satisfy all constraints and limit or minimize the number of successive weeks with weekend work.
Dexamethasone Modulates IL-13 and IL-10 Expression (1997)

Interleukin (IL-)-10 and IL-13 are Th2-cell-associated cytokines with a variety of biologic activities in immune and inflammatory responses. It is known that glucocorticoids (GCs) modulate inflammatory and immune functions. In fact, GCs are involved to regulate the transcription of cytokines which are relevant in chronic inflammation and cell-mediated immune response. In the present study we analyzed, in vitro, the effects of DEX on the expression of the IL-10 and IL-13 lymphokines in murine spleen and thymus cells. DEX-stimulation induced down-regulation of the expression of IL-10 and IL-13 mRNA. This effect was already evident 0.5 hr after treatment and persisted in time, in both resting and activated lymphocytes. These results suggest that GCs could have inhibitory effect on Th2 cytokine production.
Hollow graphene oxide spheres self-assembled by W/O emulsion (2010)

Hollow graphene oxide spheres (HGOSs) were fabricated from graphene oxide nanosheets (GONs) utilizing a water-in-oil (W/O) emulsion technique without surfactant. Effects of oxidation treatment and water removal on the formation and morphology of HGOSs are investigated. The oxidation time for preparing GONs is a crucial factor for the formation and morphology of HGOSs. We found that with increasing oxidation time, the morphology and surface topography of HGOSs vary from irregular and rough to uniform and smooth shape with decreasing diameter. Moreover, the electrochemical performance of HGOSs as anode materials in lithium-ion batteries was evaluated. The heat-treated HGOSs exhibit a 485 mAh g−1 reversible capacity and high rate performance thanks to the hollow structure, thin and porous shells consisting of graphene.
Strength characteristics of hydraulic lime mortared brickwork (2008)

This paper presents experimental results from an ongoing study investigating the flexural bond strength, initial shear strength and compressive strength of brickwork built using natural hydraulic lime mortars. All tests were conducted in accordance with relevant standard procedures. Flexural bond strengths, with planes of failure parallel and perpendicular to bed joints, were determined by panel (wallette) tests. Bond wrench testing of stack-bonded prisms was also conducted to investigate further the material influences on flexural strength. The main parameters studied in this investigation were mortar mix design (binder : aggregate ratio; lime grade) and brick water absorption characteristics. The flexural bond strength and initial shear strength of the brickwork in general increased with mortar strength, but flexural bond strength was significantly impaired by both low and high brick water absorption. The bond wrench test was found to be a reliable, quick and easy, alternative test procedure to determine flexural strength (with plane of failure) parallel to the bed joints.

Neural Control of Fast Nonlinear Systems— Application to a Turbocharged SI Engine With VCT (2007)

Today, (engine) downsizing using turbocharging appears as a major way in reducing fuel consumption and pollutant emissions of spark ignition (SI) engines. In this context, an efficient control of the air actuators [throttle, turbo wastegate, and variable camshaft timing (VCT)] is needed for engine torque control. This paper proposes a nonlinear model-based control scheme which combines separate, but coordinated, control modules. Theses modules are based on different control strategies: internal model control (IMC), model predictive control (MPC), and optimal control. It is shown how neural models can be used at different levels and included in the control modules to replace physical models, which are too complex to be online embedded, or to estimate nonmeasured variables. The results obtained from two different test benches show the real-time applicability and good control performance of the proposed methods.
Working Paper: Ethical Issues Arising from Trans-Species Gene Transfer (2006)

The general public has a variety of ethical concerns about trans-species gene transfer, including: - threats to the integrity of organisms; - threats to the intrinsic value of the natural world; - threats to cultural and social identity; and - threats to specific communities. 剔he general public's definition of species may be related to but not the same as the scientific definition. Science and ethics are connected, and distinctions between organisms based on cultural, social and religious convictions are as valid as scientific distinctions. Both views can contribute valid criteria to determine what is ethically acceptable in trans-species gene transfer. The general public's concerns about trans-species gene transfer may not always align with the taxonomic levels of separation between species; however, it is important to consider these different ways of understanding organisms when engaging in debate about the ethics of trans-species gene transfer. Many of the issues associated with trans-species gene transfer are not solely scientific and technical, but also ethical, medical, legal, social and cultural. If the scientific argument dominates the public debate, the input of those who are not scientific experts may be seen as subjective and personal. A coordinated approach is required so that the various arguments can be considered on their respective merits. Proponents of the different ethical arguments about gene transfer often fail to understand the value of alternative arguments. This problem must be overcome before the ethical issues can be effectively debated.
The photocycle and ultrafast vibrational dynamics of bacteriorhodopsin in lipid nanodiscs (2014)

The photocycle and vibrational dynamics of bacteriorhodopsin in a lipid nanodisc microenvironment have been studied by steady-state and time-resolved spectroscopies. Linear absorption and circular dichroism indicate that the nanodiscs do not perturb the structure of the retinal binding pocket, while transient absorption and flash photolysis measurements show that the photocycle which underlies proton pumping is unchanged from that in the native purple membranes. Vibrational dynamics during the initial photointermediate formation are subsequently studied by ultrafast broadband transient absorption spectroscopy, where the low scattering afforded by the lipid nanodisc microenvironment allows for unambiguous assignment of ground and excited state nuclear dynamics through Fourier filtering of frequency regions of interest and subsequent time domain analysis of the retrieved vibrational dynamics. Canonical ground state oscillations corresponding to high frequency ethylenic and C-C stretches, methyl rocks, and hydrogen out-of-plane wags are retrieved, while large amplitude, short dephasing time vibrations are recovered predominantly in the frequency region associated with out-of-plane dynamics and low frequency torsional modes implicated in isomerization.
Client browsing module for internet collaborations (2002)

This paper presents the SHINE (Shared Internet Environment) system, which is middleware for implementing distributed networked virtual environments and virtual architectural engineering (VAE) as a pilot service of Internet collaboration. In the proposed service, three-dimensional (3D) building models drawn with CAD are exported to the XML database (DB), which stores geometry and shared properties of each building component. The SHINE browser parses XML documents from the XML DB and renders 3D models using X3D components and the JavaBeans virtual component library. Users participating in VAE can view and design 3D models with a sense of sharing space, presence and time.
Delta-Like Ligand 4–Notch Blockade and Tumor Radiation Response (2011)

The combination of specific DLL4-Notch blockade and ionizing radiation impairs tumor growth by promoting nonfunctional tumor angiogenesis and extensive tumor necrosis, independent of tumor DLL4 expression.
Li-doped ZnSe epitaxial layers by ion implantation (1988)

Li+ ions were implanted into undoped high crystalline quality ZnSe epilayers grown by metalorganic vapor phase epitaxy. Thermal annealing after ion implantation was performed between 451 and 757 °C. The total photoluminescence intensity (measured at 77 K) of implanted layers before annealing was two orders of magnitude less than that of an as-grown one because of the Li+ ion damage. As the annealing temperature was increased, however, the damage was reduced and the photoluminescence intensities of two main peaks (band-edge emission and strong free to acceptor transition emission) became intense without generating deep centers. At 4.2 K, the only emission observed was associated with acceptor bound exciton and donor acceptor pair recombination in the near-band-edge region.
Induction of protective immune response in cats by vaccination with feline leukemia virus iscom. (1985)

An effective candidate subunit vaccine consisting of the gp 70/85 of feline leukemia virus (FeLV) was prepared by using the immunostimulating complex (iscom) method for the presentation of membrane proteins of enveloped viruses. Two 32-wk-old specific pathogen-free (SPF) cats were immunized with a FeLV iscom vaccine prepared from the supernatant fluid of the FL74 tumor cell line without adjuvant. Both cats developed FeLV serum antibodies, as measured in an enzyme-linked immunosorbent assay (ELISA) and in a virus neutralization test. A proportion of the antibodies were directed to an epitope located on gp70/85, which was shown in competition ELISA with a peroxidase-labeled virus-neutralizing monoclonal antibody to be shared by all three subtypes of FeLV. The protective effect of FeLV iscom was studied by vaccinating six 8-wk-old SPF cats with iscom prepared from cell culture supernatant of another tumor cell line F422, followed by oronasal challenge with 10(6) ffu FeLV-A (strain Glasgow-1). Six unvaccinated cats were also challenged with the same dose of FeLV. The vaccinated cats developed FeLV serum antibodies, some of which were directed to the shared epitope on gp70/85. At 10 wk after challenge, none was viremic, whereas three of the control cats had developed FeLV viremia. The potential of FeLV iscom as a vaccine against FeLV-associated disease in cats, and of iscom vaccines for protection against mammalian retrovirus infections, is discussed.
Polarization of lasing emission in microdisk laser diodes (1995)

TE polarization of optical emission from microdisk laser diodes of radius R=5 μm, thickness L=0.3 μm, is found to dominate both below and above room-temperature lasing threshold current, Ith=2 mA. TE emission in the lasing mode at λ=1560 nm wavelength is due to higher optical gain for TE modes in the quantum well device. In our device geometry, the intrinsic whispering gallery resonances have essentially no polarization selectivity.
Dismt - Determination of mixing time through color changes (2002)

The DISMT ("Dual Indicator System for Mixing Time'') mixing time/distance diagnostic encodes semi-quantitative visualization of liquid/liquid mixing processes in color changes. In DISMT, two liquids, one red and one blue, are mixed to produce a yellow liquid. Through appropriate choice of the acid-base indicators used, and the initial pH's of the two solutions, the yellow liquid appears only in those regions where the mixing fraction is within a designated fractional deviation (say 5%) of the infinite time mixing fraction. Thus, the 95% mixing time/ distance can be defined, for the whole volume of the mixing system, as the time/distance for all of the liquid to become yellow. This paper describes: (1) the principles underlying and choices involved in the design of DISMT systems, (2) protocols for carrying out DISMT-based experiments, and (3) examples of results obtained with DISMT.
Purification and Properties of an α-Glucosidase (Glucoamylase) in Sugar Beet Seed (1978)

An α-glucosidase which was homogeneous in ultracentrifugal and disc electrophoretic analyses was purified from sugar beet seed by fractionation with ammonium sulfate, chromatography on CM-celluIose and gel filtrations on Bio-Gel P–150. The sedimentation coefficient (s20, w) was calculated to be 5.9S, The molecular weight was estimated to be approximately 9.1 x 104 by SDS-disc electrophoresis. The α-glucosidase showed also the pronounced glucoamylase activity. The optimal pH was found to be in the range of 4.1 to 4.7 for both maltose and soluble starch. The enzyme exhibited higher substrate-binding affinity and hydrolytic activity toward soluble starch than toward maltose. The ratio of initial velocity of hydrolysis for maltose (Km, 6.8 mg/ml) and soluble starch (Km, 1.9 mg/ml) was calculated to be 100: 120 in this order. The enzyme is an interesting type of α-glucosidase which may be regarded as glucoamylase.
