Modeling,Computation and simulaitn of non-linear soft-tissue interaction with flow dynamics with application to biological systems (2016)

In this work, a computational model for the interaction of blood flow with the wall of an intracranial saccular aneurysm that is surrounded by cerebral spinal fluid is considered. The coupled fluid-structure interaction model presented includes growth and remodeling effects within the soft-tissue by incorporating elastin and collagen dynamics which are two of the main layers in the arterial wall. The resulting nonlinear system of coupled differential equations are solved numerically using implicit finite difference methods coupled with the Newton's method. The linearized version of the nonlinear system was also considered and solved both analytically using Laplace transformation and numerically using implicit finite difference methods. The nonlinear effects on rupture was studied and compared for benchmark studies and the computational results indicate that the model proposed is robust and reliable.
Tissue Selectivity of Interferon-Stimulated Gene Expression in Mice Infected with Dam+versus Dam−Salmonella entericaSerovar Typhimurium Strains (2002)

The host interferon (IFN) system plays an important role in protection against microbial infections. Salmonella enterica serovar Typhimurium is highly virulent in the mouse model, whereas mutants that lack DNA adenine methylase (Dam(-)) are highly attenuated and elicit fully protective immune responses against murine typhoid fever. We examined the expression of IFN-responsive genes in several mouse tissues following infection with Dam(+) or Dam(-) Salmonella. Infection of mice with Dam(+) Salmonella resulted in the induction of host genes known to be indicators of IFN bioactivity and regulated by either IFN-alpha/beta (Mx1) or IFN-gamma (class II transactivator protein [CIITA] and inducible nitric oxide synthase [iNOS]) or by both IFN-alpha/beta and IFN-gamma (RNA-specific adenosine deaminase [ADAR1] and RNA-dependent protein kinase [PKR]) in a tissue-specific manner compared to uninfected animals. Since the Mx1 promoter is IFN-alpha/beta specific and the Mx1 gene is not inducible directly by IFN-gamma, these data suggest a role of IFN-alpha/beta in the host response to Salmonella infection. Mice infected with Dam(-) Salmonella showed reduced expression of the same set of IFN-stimulated genes (ISGs) as that observed after infection with wild-type Salmonella. The reduced capacity to induce ISGs persisted in Dam(-)-vaccinated mice after challenge with the virulent (Dam(+)) strain. Finally, although no Dam(-) organisms were recovered from the liver or spleen after oral infection of mice, ADAR, PKR, Mx, and CIITA expression levels were elevated in these tissues relative to those in uninfected mice, suggestive of the distant action of a signaling molecule(s) in the activation of ISG expression.

Conjugate Addition of Diboron Catalyzed by O-Monoacyltartaric Acids (2015)

<i>O</i>-3,5-Di(adamantan-1-yl)benzoyltartaric acid catalyzes the conjugate addition of bis(neopentyl glycolato)diboron to α,β-unsaturated ketones with good enantioselectivity. The addition of magnesium sulfate as a dehydrating agent and benzoic acid as a co-catalyst was found to be effective.
Operator-based over-the-air M2M wireless sensor network security (2010)

We describe a novel method for over-the-air automated authentication and verification of machine-to-machine (M2M) wireless sensor networks using the existing authentication assets of a cellular telecom operator. We extend the standard Generic Bootstrapping Architecture (GBA) provided in the 3GPP specifications to implement our solution with minimal additional hardware and software requirements.
The influence of in-cylinder flows and bulk gas density on early Spray G injection in an optical research engine (2021)

A well-characterized multi-hole gasoline injector, the Engine Combustion Network’s (ECN) Spray G injector, was investigated in an optically accessible research engine under four motored operating conditions with early injection. The experiments were conducted at intake pressures of [Formula: see text] and [Formula: see text], nearly matching the ECN’s standard early injection operating conditions, Spray G2 (flash boiling) and Spray G3 (early injection), respectively. This was combined with two engine speeds at [Formula: see text] and [Formula: see text]. Using particle image velocimetry and volumetric Mie scatter imaging, the in-cylinder flows were evaluated and the effects on the spray morphology were characterized. The in-cylinder flow was evaluated to understand the spray-flow interaction, including the turbulent kinetic energy. Little effect on turbulent energy was observed in the region examined near the exit of the fuel injector nozzle shortly after injection. Mie scatter imaging was used to characterize the spray morphology and wall wetting was clearly visible on the spark plug. Cyclic variability of the sprays was found to be insignificant; and major differences in spray morphology are attributed to the in-cylinder velocity and intake pressure at the time of injection. Decreasing the bulk gas density by decreasing the intake pressure had a number of effects on the evolution of the spray including faster evaporation, increased axial liquid penetration, and decreased spray angle. Increasing the in-cylinder flow magnitudes by increasing the engine speed had a similar effect on spray morphology by also increasing the evaporation rate, increasing the axial penetration, and decreasing the spray opening angle. Comparison of the motored spray cases with a no-flow case (when the fuel is sprayed into the engine without the piston present) further illustrated the extent to which the intake flow influenced the spray shape.
Light Microscopy Techniques for Live Cell Imaging (2003)

Since the earliest examination of cellular structures, biologists have been fascinated by observing cells using light microscopy. The advent of fluorescent labeling technologies plus the plethora of sophisticated light microscope techniques now available make studying dynamic processes in living cells almost commonplace. For anyone new to this area, however, it can be daunting to decide which techniques or equipment to try. Here, we aim to give a brief overview of the main approaches to live cell imaging, with some mention of their pros and cons.
Molecular analysis of chromosome 14q32 abnormalities in esophageal and gastric carcinoma (1998)

To clarify the chromosome 14q32 abnormalities present in esophageal carcinoma and gastric carcinoma at the molecular level, we applied the fluorescence in situ hybridization (FISH) technique to metaphases of 16 esophageal carcinoma cell lines and used PCR-SSCP to analyze loss of heterozygosity (LOH) in 60 gastric carcinomas. Chromosome abnormalities associated with the 14q32 region occurred in 7 out of 16 esophageal cell lines. There were two different breakpoint cluster regions. One was found within or more telomeric to the variable region of the immunoglobulin heavy chain locus. Another breakpoint was located in the region between the tcl-1 locus and the D14S19 locus. PCR-SSCP showed that 51.7% of the 60 gastric carcinomas had LOH for at least one locus on chromosome 14 q 24-32, and this region overlapped with one of the breakpoint cluster regions found in the esophageal carcinoma cell lines. Frequent genetic abnormalities around this region have been found in colorectal carcinoma, neuroblastoma, bladder carcinoma, and ovarian carcinoma by RFLP analysis and cytogenetic studies. Taking those previous studies and our results together, it is hypothesized that the telomeric region of chromosome 14 may contain a tumor suppressor gene, inactivation of which might be caused by chromosomal translocation as well as allelic loss of this region.
Detection of novel chlamydiae in cats with ocular disease (2003)

Application of a broad-range detection method resulted in identification of a new agent associated with ocular disease in cats. Finding chlamydia-like agents such as N hartmannellae in coinfections with their obligate amebic host, Hartmannella vermiformis, raises questions about the potential role of these microorganisms in causation or exacerbation of ocular disease in cats.
NeRFactor: Neural Factorization of Shape and Reflectance Under an Unknown Illumination (2021)

We address the problem of recovering the shape and spatially-varying reflectance of an object from multi-view images (and their camera poses) of an object illuminated by one unknown lighting condition. This enables the rendering of novel views of the object under arbitrary environment lighting and editing of the object's material properties. The key to our approach, which we call Neural Radiance Factorization (NeRFactor), is to distill the volumetric geometry of a Neural Radiance Field (NeRF) [Mildenhall et al. 2020] representation of the object into a surface representation and then jointly refine the geometry while solving for the spatially-varying reflectance and environment lighting. Specifically, NeRFactor recovers 3D neural fields of surface normals, light visibility, albedo, and Bidirectional Reflectance Distribution Functions (BRDFs) without any supervision, using only a re-rendering loss, simple smoothness priors, and a data-driven BRDF prior learned from real-world BRDF measurements. By explicitly modeling light visibility, NeRFactor is able to separate shadows from albedo and synthesize realistic soft or hard shadows under arbitrary lighting conditions. NeRFactor is able to recover convincing 3D models for free-viewpoint relighting in this challenging and underconstrained capture setup for both synthetic and real scenes. Qualitative and quantitative experiments show that NeRFactor outperforms classic and deep learning-based state of the art across various tasks. Our videos, code, and data are available at people.csail.mit.edu/xiuming/projects/nerfactor/.
Additive Manufactured Filtering Lens Antennas for Radar Measurements at 240 GHz (2022)

In this work, a novel approach for 3D-printed, frequency selective lens antennas is presented. Modern frequency modulated continous wave (FMCW) radar sensors based on monolithic microwave integrated circuits (MMIC) operating beyond 100 GHz often use system concepts with a signal generation at lower frequencies, followed by frequency multipliers. This often leads to an unwanted feed-through signal of the fundamental tone in the output spectrum. In FMCW operation, this fundamental feed-through signal generates false targets in the range spectrum. Additionally, the unwanted radiation may be problematic for legal conformity or electromagnetic interference compliance. To suppress this fundamental feed-through signal, a filter structure is integrated in a lens antenna, filtering the unwanted signal, while the desired output signal is radiated. The developed lens antenna structures were fabricated by additive manufacturing using Selective Laser Sintering (SLS) and Stereolithography (SLA) techniques, allowing easy and cost effective production of complex structures. Both techniques were compared regarding the printing material and its suitability for high frequency lens antenna design. In the end, radar measurements are shown to demonstrate the successful suppression of false targets caused by fundamental feed-through signals.
Follow-up respiratory function of a patient treated with a membrane lung. (1975)

A patient in remission from acute lymphoblastic leukemia developed the adult respiratory distress syndrome. Despite "optimal respiratory therapy" and ventilatory assistance with 100 per cent inspired O2 (fraction of inspired O2 = 1) and 15 cm of positive end-expiratory pressure, the patient's arterial PO2 remained at 33 mm Hg. Prepulmonary venovenous respiratory support was given for 10 days with a spiral coil membrane lung. The data document the sequential improvement in respiratory function and suggest that despite the severe lung damage that may occur during the adult respiratory distress syndrome treated with prolonged high inspired concentration of O2, if the patient's lungs recover from the acute process, the respiratory system can recover so that there is little, if any, permanent restriction of the subject's activities as a result of respiratory impairment.
Surface Plasmon Resonance (2002)

Abstract Surface plasmon resonance is an optical resonance effect where the back side of a thin conductive mirror affects the angle at which there is a minimum of reflected light.
Properties of NADH-cytochrome-b5 reductase from human neutrophils (1983)

An NADH-ferricyanide reductase activity of ca. 170 nmole ferricyanide reduced/min/10(7) cells is present in the membrane fraction of human neutrophils. This membrane-bound activity constitutes ca. 85% of the total NADH-ferricyanide reductase activity that is present in these cells. The enzyme(s) readily utilize(s) purified cytochrome-b5 from beef liver as an electron acceptor. No other physiologic electron acceptors tested (e.g., ubiquinone-30, menadione) were active. The specificities of electron donors (e.g., NADH congruent to deamino-NADH much greater than NADPH) and acceptors (e.g., Fe(CN)6-3 greater than 2,6-dichlorophenol-indophenol much greater than O2) for the enzyme(s) in unfractionated membranes, along with action of inhibitors (e.g., ADP, p-chloromercuribenzoate) and the pH optimum, indicate that virtually all of the membrane-bound ferricyanide reductase activity in these cells is NADH-cytochrome-b5 reductase. This reductase, however, is only slightly solubilized (ca. 10%) by a phosphate buffer extraction procedure that is effective with the liver enzyme.
The Combination of Nanolime Dispersions with Silicic Acid Esters (2018)

Fundamentals of the application of silicic acid ester will be summarised in the following together with possible combinations with nanolime. The combined application of nanolime and silicic acid esters is possible in two ways: as a homogeneous mixture, and by consecutive applications of nanolime dispersions and silicic acid esters (SAEs). Esters are compounds that are obtained by a reaction between alcohols and acids. Silicic acid esters are formally the products of reactions between silicic acid and different alcohols. The application of SAE for clay-based materials as well as for calcareous minerals and materials has been the subject of controversial discussions. Instead of using homogeneous mixtures of calcium hydroxide nanosols and SAEs, a successive application of both components is possible. Compared to the application of homogeneous nanolime-SAE mixtures, the consecutive application of nanolime and SAEs achieves greater strengthening. The most noticeable influence of nanolime could be observed during the consolidation of weak and deteriorated materials, both natural stones and mortars.
Primary Structure of Striped Dolphin Renal Metallothionein II (1988)

The complete amino acid sequence of metallothionein II isolated from kidneys of the striped dolphin, Stenella coeruleoalba, is reported. The sequence was established by a gas phase protein sequencer using the fragments obtained by cyanogen bromide cleavage and protease digestions of the S-carboxamidomethylated protein. The N-terminal was identified as acetylmethionine by 1H-NMR and MS using the N-terminal dipeptide obtained by formic acid hydrolysis. The C-terminal amino acid was assigned as alanine using both carboxypeptidase and trypsin digests. Remarkable sequence homology was observed between dolphin and mammalian metallothionein II.
Long-Tail Statistics of the Purcell Factor in Disordered Media Driven by Near-Field Interactions (2011)

In this Letter, we study the Purcell effect in a 3D disordered dielectric medium through fluorescence decay rates of nanosized light sources. We report distributions of Purcell factor with non-Gaussian long-tailed statistics and an enhancement of up to 8 times the average value. We attribute this large enhancement to strong fluctuations of the local density of states induced by near-field scattering sustained by more than one particle. Our findings go beyond standard diagrammatic and single-scattering models and can be explained only by taking into account the full near-field interaction.
A Multibody Approach to the Analysis of Helicopter-Terrain Interaction (2002)

The paper presents an analysis of the significant aspects related to the interaction between rotorcrafts and the terrain. It addresses the analysis of a typical medium weight helicopter, with detailed wheel landing gear and full rotor dynamics, during significant maneuvers. The aim of this work is in fact, on one hand, to investigate the interaction between the landing devices and the terrain under realistic conditions, such as those obtained by simultaneously modeling the dynamics of the helicopter rotor. On the other hand, it is aimed at analyzing the effects of realistic ground loads on the rotor components. The validity of the multibody/multidisciplinary approach for this kind of problems is discussed.

Evaluation of Antimicrobial Activity of Triphala Constituents and Nanoformulation (2020)

The prevalence of nosocomial infections due to multidrug resistant (MDR) bacterial strains is associated with high morbidity and mortality. Folk medicine and ethnopharmacological data can provide a broad range of plants with promising antimicrobial activity. Triphala, an Ayurvedic formula composed of three different plants: <i>Terminalia chebula</i> Retz., <i>Terminalia bellirica</i> (Gaertn.) Roxb. (Combretaceae), and <i>Phyllanthus emblica</i> L. (Phyllanthaceae), is used widely for various microbial infections. Various extraction techniques were applied in the extraction of the biologically active constituents of Triphala in order to compare their efficiency. Microwave-assisted extraction (MAE) was shown to be the most efficient method based on yield, extraction time, and selectivity. The Triphala hydroalcoholic extract (TAE) has been chemically characterized with spectroscopic and chromatographic techniques. Triphala hydroalcoholic extract was evaluated alone or with carvacrol. Different drug formulations including cream and nanoemulsion hydrogel were prepared to assess the antimicrobial activity against selected microorganism strains including Gram-positive and Gram-negative bacteria and fungi. We used a lipophilic oil of carvacrol (5 mg/mL) and a hydrophilic TAE (5 mg/mL) ingredient in a dosage form. Two solutions were created: hydrogel containing nanoemulsion as a lipophilic vector dispersed in the gel as a hydrophilic vehicle and a cream formulation, an oil-in-water emulsion. In both cases, the concentration was 250 mg of active ingredient in 50 mL of final formulation. The formulas developed were stable from a physical and chemical perspective. In the nanoemulsion hydrogel, the oil droplet size ranged from 124 to 129 nm, with low polydispersity index (PdI) 0.132 ± 0.013 and negative zeta potential -46.4 ± 4.3 mV. For the cream, the consistency factor (cetyl alcohol and white wax) induced immobilization of the matrix structure and the stability. Triphala hydroalcoholic extract in drug nanoformulation illustrated might be an adjuvant antimicrobial agent for treating various microbial infections.
Monomeric Thallium(I) Complexes of Fluorinated Triazapentadienyl Ligands (2005)

Rare examples of thallium monocoordination? Polyfluorinated triazapentadienes HN[C(C3F7)NAr]2 with bulky aryl substituents react with TlOEt to give rare, monomeric thallium(I) complexes in which the TlI center coordinates to the central nitrogen atom of the W-shaped triazapentadienyl ligand system (see figure; Ar=2,4,6-trimethylphenyl; N: blue, F: yellow, Tl: green).
