A Public Shuffle without Private Permutations. (2012)

Abstract. In TCC 2007, Adida and Wikström proposed a novel approach to shuffle, called a public shuffle, in which a shuffler can perform shuffle publicly without needing information kept secret. Their scheme uses an encrypted permutation matrix to shuffle ciphertexts publicly. This approach significantly reduces the cost of constructing a mix-net to verifiable joint decryption. Though their method is successful in making shuffle to be a public operation, their scheme still requires that some trusted parties should choose a permutation to be encrypted and construct zero-knowledge proofs on the well-formedness of this permutation. In this paper, we propose a method to construct a public shuffle without relying on permutations and randomizers generated privately: Given an n-tuple of ciphertext (c1,..., cn), our shuffle algorithm computes fi(c1,..., cn) for i = 1,..., ℓ where each fi(x1,..., xn) is a symmetric polynomial in x1,..., xn. Depending on the symmetric polynomials we use, we propose two concrete constructions. One is to use ring homomorphic encryption with constant ciphertext complexity and the other is to use simple ElGamal encryption with linear ciphertext complexity in the number of senders. Both constructions are free of zero-knowledge proofs and publicly verifiable.
A Proteomic Connectivity Map for Characterizing the Tumor Adaptive Response to Small Molecule Chemical Perturbagens (2019)

A powerful means to understand the cellular function of corrupt oncogenic signaling programs requires perturbing the system and monitoring the downstream consequences. Here, using a unique pair of non-small cell lung cancer (NSCLC)/normal lung epithelial patient-derived cell lines (HCC4017/HBEC30KT), we systematically interrogated the remodeling of the NSCLC proteome upon treatment with 35 chemical perturbagens targeting a diverse array of mechanistic classes. HCC4017 and HBEC30KT cells differ significantly in their proteomic response to the same compound treatment. Using protein covariance analyses, we identified a large number of functional protein networks. For example, we found that a poorly studied protein, C5orf22, is a novel component of the WBP11/PQBP1 splicing complex. Depletion of C5orf22 leads to the aberrant splicing and expression of genes involved in cell growth and immunomodulation. In summary, we show that by systematically measuring the tumor adaptive responses at the proteomic level, an understanding could be generated that provides critical circuit-level biological insights for these pharmacologic perturbagens.
Enabling Low-Cost CO2 Capture via Heat Integration (2010)

Hollow fiber sorbents in rapid thermal swing mode, packed bed solid sorbents in thermal swing mode, hollow fiber membranes, monoethanolamine-based liquid amines, and chilled ammonia CO2 sorption systems are compared on an energetic basis for CO2 capture from coal-fired power plants. The systems are compared on an intrinsic heat and auxiliary basis both with and without plantwide heat integration efforts. Without heat integration, every technology considered was shown to be highly parasitic, consuming between 1.0 and 4.0 GJ/(ton of CO2 captured) (effectively between 40 and 100% parasitic, depending on plant efficiencies). When heat integration strategies are considered, such as utilizing feedwater preheating heat flows (without disrupting plant operation) and utilizing heats generated during CO2 compression, the overall parasitic nature of the technologies decreases dramatically. Namely, chilled ammonia and zeolite MFI-based fiber sorbents consume approximately 0.07 and 0.13 GJ/(ton of CO2 captured), respectively. The overall energetic analysis strongly suggests that CO2 capture systems must be highly integrated with the plant systems for successful widespread deployment as retrofits to large power plants.
First atmospheric results produced by the SuperCam instrument on Mars2020 (2022)

The SuperCam instrument [1,2] onboard Mars2020 disposes of a variety of active and passive techniques, including passive spectroscopy in the 0.40-0.85 (VIS) and 1.3 to 2.6 microns (IR, [3,4]) wavelength ranges. Since the landing on Mars of Perseverance in February 2021, Supercam has acquired numerous observations of its near and distant environment, exploring the geological and mineralogical context of Jezero crater. In addition, several measurements were devoted to probing the atmosphere surrounding the Perseverance rover. The technique of using sky spectra in passive mode, known as “passive sky”, has already been demonstrated with ChemCam on the Mars Science Laboratory (MSL) rover [4]. SuperCam provides a superset of the ChemCam capabilities used in [4], and in particular adds a near-infrared component that includes absorption and scattering characteristics of key gases and aerosols/clouds. “Passive sky” measurements have typically been performed every other week to allow a consistent monitoring of the seasonal evolution of the main quantities (CO2, O2, H2O, CO, aerosols/clouds). Particular attention was given to joint measurements of O2 and CO, as they appear as key components of the Martian chemical cycle and have never been measured together at the same time on the surface of Mars. As the 2 μm wavelength region is used for the first time at the surface of Mars, it enables the detection of CO (around 2.35 μm). CO possesses a small absorption that has made it difficult to identify in SuperCam spectra so far. An overview of SuperCam’s progress to date in its attempt to characterize the Martian atmosphere at Jezero will be presented. References : [1] Wiens, R.C., et al. , 2021.

Intrarenal Dopamine D1-Like Receptor Stimulation Induces Natriuresis via an Angiotensin Type-2 Receptor Mechanism (2006)

We explored the effects of direct renal interstitial stimulation of dopamine D(1)-like receptors with fenoldopam, a selective D(1)-like receptor agonist, on renal sodium excretion and angiotensin type-2 (AT(2)) receptor expression and cellular distribution in rats on a high-sodium intake. In contrast to vehicle-infused rats, sodium excretion increased in fenoldopam-infused rats during each of three 1-hour experimental periods (<0.001). Blood pressure was unaffected by vehicle or fenoldopam. In plasma membranes of renal cortical cells, fenoldopam increased D(1) receptor expression by 38% (P<0.05) and AT(2) receptor expression by 69% (P<0.01). In plasma membranes of renal proximal tubule cells, fenoldopam increased AT(2) receptor expression by 108% (P<0.01). In outer apical membranes of proximal tubule cells, fenoldopam increased AT(2) receptor expression by 59% (P<0.01). No significant change in total AT(2) receptor protein expression was detectable in response to fenoldopam. Fenoldopam-induced natriuresis was abolished when either PD-123319, a specific AT(2) receptor antagonist, or SCH-23390, a potent D(1)-like receptor antagonist, was coinfused with F (P<0.001). In summary, direct renal D(1)-like receptor activation increased urinary sodium excretion and the plasma membrane expression of AT(2) receptors in renal cortical and proximal tubule cells. D(1)-like receptor-induced natriuresis was abolished by intrarenal AT(2) receptor inhibition. These findings suggest that dopaminergic regulation of sodium excretion involves recruitment of AT(2) receptors to the outer plasma membranes of renal proximal tubule cells and that dopamine-induced natriuresis requires AT(2) receptor activation.

Advanced silicon processing for active planar photonic devices (2009)

Using high quality, anisotropically etched Si waveguides bonded to InGaAsP, the authors demonstrate a hybrid laser, whose optical profile overlaps both Si and III-V regions. Continuous wave laser operation was obtained up to 45°C, with single facet power as high as 12.7mW at 15°C. Planar Si optical resonators with Q=4.8×106 are also demonstrated. By using a SF6∕C4F8 reactive ion etch, followed by H2SO4∕HF surface treatment and oxygen plasma oxide, the optical losses due to the waveguide and the bonding interface are minimized. Changes of optical confinement in the silicon are observed due to waveguide width variation.

How to Combine Membership-Inference Attacks on Multiple Updated Machine Learning Models (2023)

A large body of research has shown that machine learning models are vulnerable to membership inference (MI) attacks that violate the privacy of the participants in the training data. Most MI research focuses on the case of a single standalone model, while production machine-learning platforms often update models over time, on data that often shifts in distribution, giving the attacker more information. This paper proposes new attacks that take advantage of one or more model updates to improve MI. A key part of our approach is to leverage rich information from standalone MI attacks mounted separately against the original and updated models, and to combine this information in specific ways to improve attack effectiveness. We propose a set of combination functions and tuning methods for each, and present both analytical and quantitative justification for various options. Our results on four public datasets show that our attacks are effective at using update information to give the adversary a significant advantage over attacks on standalone models, but also compared to a prior MI attack that takes advantage of model updates in a related machine-unlearning setting. We perform the first measurements of the impact of distribution shift on MI attacks with model updates, and show that a more drastic distribution shift results in significantly higher MI risk than a gradual shift. We also show that our attacks are effective at auditing differentially private fine tuning. We make our code public on Github: https://github.com/stanleykywu/model-updates.
Foulant Identification and Performance Evaluation of Antiscalants in Increasing the Recovery of a Reverse Osmosis System Treating Anaerobic Groundwater (2022)

The objectives of this study are to assess the performance of antiscalants in increasing the recovery (≥85%) of a reverse osmosis (RO) plant treating anaerobic groundwater (GW) in Kamerik (the Netherlands), and to identify scalants/foulant that may limit RO recovery. Five different commercially available antiscalants were compared on the basis of their manufacturer-recommended dose. Their ability to increase the recovery from 80% to a target of 85% was evaluated in pilot-scale measurements with anaerobic GW and in once-through lab-scale RO tests with synthetic (artificial) feedwater. A membrane autopsy was performed on the tail element(s) with decreased permeability. X-ray photoelectron spectroscopy (XPS) analysis indicated that calcium phosphate was the primary scalant causing permeability decline at 85% recovery and limiting RO recovery. The addition of antiscalant had no positive effect on RO operation and scaling prevention, since at 85% recovery, permeability of the last stage decreased with all five antiscalants, while no decrease in permeability was observed without the addition of antiscalant at 80% recovery. In addition, in lab-scale RO tests executed with synthetic feed water containing identical calcium and phosphate concentrations as the anaerobic GW, calcium phosphate scaling occurred both with and without antiscalant at 85% recovery, while at 80% recovery without antiscalant, calcium phosphate did not precipitate in the RO element. In brief, calcium phosphate appeared to be the main scalant limiting RO recovery, and antiscalants were unable to prevent calcium phosphate scaling or to achieve a recovery of 85% or higher.
Polymeric Systems Incorporating Plant Viral Nanoparticles for Tailored Release of Therapeutics (2013)

Therapeutic polylactide (PLA) nanofibrous matrices are fabricated by incorporating plant viral nanoparticles (PVNs) infused with fluorescent agents ethidium bromide (EtBr) and rhodamine (Rho), and cancer therapeutic doxorubicin (Dox). The native virus, Red clover necrotic mosaic virus (RCNMV), reversibly opens and closes upon exposure to the appropriate environmental stimuli. Infusing RCNMV with small molecules allows the incorporation of PVN(Active) into fibrous matrices via two methods: direct processing by in situ electrospinning of a polymer and PVNs solution or immersion of the matrix into a viral nanoparticle solution. Five organic solvents commonly in-use for electrospinning are evaluated for potential negative impact on RCNMV stability. In addition, leakage of rhodamine from the corresponding PVN(Rho) upon solvent exposure is determined. Incorporation of the PVN into the matrices are evaluated via transmission electron, scanning electron and fluorescent microscopies. Finally, the percent cumulative release of doxorubicin from both PLA nanofibers and PLA and polyethylene oxide (PEO) hybrid nanofibers demonstrate tailored release due to the incorporation of PVN(Dox) as compared to the control nanofibers with free Dox. Preliminary kinetic analysis results suggest a two-phase release profile with the first phase following a hindered Fickian transport mechanism for the release of Dox for the polymer-embedded PVNs. In contrast, the nanofiber matrices that incorporate PVNs through the immersion processing method followed a pseudo-first order kinetic transport mechanism.
Cooperative Data Placement and Replication in Edge Cache Networks (2006)

Cooperation among individual caches has proven to be an effective strategy to improve the scalability and performance of edge cache networks delivering dynamic Web content. To date, research in the area of cooperative edge caching has mainly focused on serving client requests and maintaining freshness of cached documents. However, designing mechanisms to effectively manage the available resources is an important challenge that can have significant impact on the performance of an edge cache network. In this paper we propose a novel data placement scheme, called the utility-based placement scheme, which is not only sensitive to the ongoing cooperation in the edge cache but also takes into account the various costs and benefits of storing a data-item at an individual edge cache. At the heart of proposed scheme is a utility function that quantifies the usefulness of storing a data-item at a particular edge cache. Experiments show that the proposed scheme provides significant performance benefits

Thermolytic Transformation of Tris(alkoxy)siloxychromium(IV) Single-Source Molecular Precursors to Catalytic Chromia−Silica Materials (2001)

Reactions of 1 and 2 equiv of HOSi(OtBu)3 with Cr(OtBu)4 afforded the first Cr(IV) alkoxysiloxy complexes (tBuO)3CrOSi(OtBu)3 (1) and (tBuO)2Cr[OSi(OtBu)3]2 (2), respectively. Both 1 and 2 contain pseudotetrahedral d2 chromium centers and crystallize in the monoclinic space group P21/n with four molecules in the unit cell. The high-yielding, convenient synthesis of 1 makes this complex a useful single-source molecular precursor, via the thermolytic molecular precursor method, to Cr/Si/O materials. The thermal transformations of 1 and 2 to chromia−silica materials occurred at low temperatures (≤180 °C), to give isobutene as the major carbon-containing product. The material generated from the solid-state conversion of 1 (CrOSiss) contained both micro- and mesoporosity with an unexpectedly high surface area of 315 m2/g that was slightly reduced to 275 m2/g after calcination at 500 °C in O2. The xerogel obtained by the thermolysis of an n-octane solution of 1 (CrOSixg) had a surface area of 315 m2/g that was reduced to 205 m2/g upon calcination at 500 °C. The nitrogen adsorption−desorption isotherm for the xerogel had characteristics indicating both microporosity and textural mesoporosity. Powder X-ray diffraction (PXRD) analysis was used to demonstrate that Cr2O3 was the only species that crystallized in CrOSiss and CrOSixg after calcination at temperatures up to 1200 °C in O2. Elemental analyses of these materials revealed that the Cr:Si ratio was very close to 1:1, indicating that the original stoichiometry of the precursor is retained upon thermal conversion to Cr/Si/O materials. Both materials contained very low amounts of carbon after calcination in O2 at 500 °C. In the oxidative dehydrogenation of propane, CrOSixg (calcined at 500 °C) displayed intrinsic activities for propene formation that were up to 3 times higher than those for CrOSiss (calcined at 500 °C). In addition, the selectivity for propene formation was higher for the more active CrOSixg catalyst.
Optimization of the electromagnetic scattering problem based on the topological derivative method (2019)

A new optimization method based on the topological derivative concept is developed for the electromagnetic design problem. Essentially, the purpose of the topological derivative method is to measure the sensitivity of a given shape functional with respect to a singular domain perturbation, so that it has applications in many relevant fields such as shape and topology optimization for imaging processing, inverse problems, and design of metamaterials. The topological derivative is rigorously derived for the electromagnetic scattering problem and used as gradient descent direction to find local optima for the design of electromagnetic devices. We demonstrate that the resulting topology design algorithm is remarkably simple and efficient and naturally leads to binary designs, while depending only on the solution of the conventional finite element formulation for electrodynamics. Finally, several numerical experiments in two and three spatial dimensions are presented to illustrate the performance of the proposed formulation.

A Torenia Mutant Bearing Shrunken Reddish-purple Flower and its Potential for Breeding (2021)

A torenia mutant, designated as “reddish purple shrunken” (RPS) because of its shrunken reddish-purple petals, was isolated from the S1 progeny of a “flecked” mutant containing an active DNA transposon Ttf1. Cyanidin-type anthocyanins—i.e., peonidin 3,5-diglucoside and cyanidin 3,5-diglucoside—were detected in petals of the RPS mutant, whereas delphinidin-type anthocyanins—i.e., malvidin 3,5-diglucoside, petunidin 3,5-diglucoside, and delphinidin 3,5-diglucoside—were the major anthocyanins in normal-type petals. Petal shrinkage could be attributed to this change in anthocyanin composition. A frameshift mutation in the first exon of flavonoid 3',5'-hydroxylase (TfF3'5'HΔC) inhibited biosynthesis of delphinidin-type anthocyanins in RPS. The “white” (W) mutant bore pure white petals in response to Ttf1 insertion in the first exon of the flavanone 3-hydroxylase gene (TfF3HTtf1). Some F2 plants derived from the cross between RPS and W bore reddish-purple petals without any shrinkage; these were designated as “reddish purple” (RP). This RP genotype was revealed as a heterozygote of TfF3H+ and TfF3HTtf1 in the background of the TfF3'5'HΔC homozygote. A gene dosage effect of TfF3H reduced anthocyanin biosynthesis in RP compared with RPS, whereas this decrease caused no reduction in visual color density. Therefore, a partial decrease in anthocyanin biosynthesis may be beneficial if petal shrinkage prevents using a new-color mutant for breeding.
