Monitoring of Liquid‐Phase Organic Reactions by Photoelectron Spectroscopy (2011)

There are strings attached: after linking the reacting groups to head groups of ionic liquids to drastically lower the vapour pressures of the reactants, ordinary liquid-phase organic reactions can be monitored by in situ X-ray photoelectron spectroscopy. This approach is demonstrated for the nucleophilic substitution of an alkyl amine and an alkyl chloride moiety, which are attached to the cation and anion of ionic liquids, respectively.
Release of a transforming growth factor (TGF)-beta 2-related suppressor factor from postimplantation murine decidual tissue can be correlated with the detection of a subpopulation of cells containing RNA for TGF-beta 2 (1992)

Postimplantation murine decidual tissue from allopregnant C3H mice has been shown to release in vitro a potent immunosuppressive factor closely related to transforming growth factor (TGF)-beta 2 but slightly lower in apparent molecular weight. Decidual suppressor factor (DSF) activity was first detected in decidual tissue supernatant at day 9.5 of gestation and reached a plateau by day 10.5 to 12.5. By Northern analysis of decidual and placental tissue with a simian TGF-beta 2 probe, two characteristic TGF-beta 2 mRNA transcripts were detected in decidual tissue. In situ hybridization analysis of C3H implant sites, with the simian (pGEM-G1G2) TGF-beta 2 riboprobe, revealed a small population of TGF-beta 2+ cells localized to postimplantation decidua basalis and metrial gland cell area after day 8.5. On and before day 8.5, when DSF was not detectable, few TGF-beta 2 mRNA+ cells were detected. To test for TGF-beta release in situ, sections of uterine tissue were stained with antibody specific for TGF-beta 2, that identified DSF in Western blots. In postimplantation tissues (day 9.5, 12.5) patchy anti-TGF-beta 2 staining was seen over decidual tissue. Before day 9.5, slight and diffuse staining over decidual tissue was present with more marked staining of extradecidual tissue. Very little staining was noted over day 9.5 decidual tissue by using anti-TGF-beta 1 antibody as a control; however, some staining was seen over postimplantation fetal trophoblast and myometrial tissue. Fractionation of disaggregated postimplantation decidua by velocity sedimentation revealed that TGF-beta 2 mRNA+ cells were predominantly small and sedimented in the same fraction(s) as those cells previously shown to release DSF in vitro. Thus, the release of TGF-beta 2 related DSF correlates with the in situ detection of TGF-beta 2 mRNA and the in situ release of TGF-beta 2 peptide. These studies suggest that DSF may be a form of TGF-beta 2 released by a population of small lymphocytic decidual suppressor cells.
DEPENDENCE OF FLEXURAL BEHAVIOR OF FIBER REINFORCED MORTAR ON MATERIAL FRACTURE RESISTANCE AND BEAM SIZE (1990)

The flexural load-deflection curves for mortar reinforced with various fiber types (steel and synthetic) and various fiber volume fractions are measured using 3 diffenect beam sizes. Three new flexural toughness indexes that reflect the general shape of the load-deflection curve are defined and calculated. The flexural strength/tensile strenth ratio f subf/f sub t is proposed as a parameter that reflects material brittleness - lower value for a more brittle material. The results are discussed.
Persistence of Cisplatin-Induced Mutagenicity in Hematopoietic Stem Cells: Implications for Secondary Cancer Risk Following Chemotherapy (2014)

Cisplatin is a cytostatic agent used in the treatment of many types of cancer, but its use is associated with increased incidences of secondary leukemia. We evaluated cisplatin's in vivo genotoxic potential by analyzing peripheral blood for Pig-a mutant phenotype erythrocytes and for chromosomal damage in the form of micronuclei. Mutant phenotype reticuloyte and erythrocyte frequencies, based on anti-CD59 antibody labeling and flow cytometric analysis, were determined in male Sprague Dawley rats treated for 28 consecutive days (days 1-28) with up to 0.4 mg cisplatin/kg/day, and sampled on days -4, 15, 29, and 56. Vehicle and highest dose groups were evaluated at additional time points post-treatment up to 6 months. Day 4 and 29 blood samples were also analyzed for micronucleated reticulocyte frequency using flow cytometry and anti-CD71-based labeling. Mutant phenotype reticulocytes were significantly elevated at doses ≥0.1 mg/kg/day, and mutant phenotype erythrocytes were elevated at doses ≥0.05 mg/kg/day. In the 0.4 mg/kg/day group, these effects persisted for the 6 month observation period. Cisplatin also induced a modest but statistically significant increase in micronucleus frequency at the highest dose tested. The prolonged persistence in the production of mutant erythrocytes following cisplatin exposure suggests that this drug mutates hematopoietic stem cells and that this damage may ultimately contribute to the increased incidence of secondary leukemias seen in patients cured of primary malignancies with platinum-based regimens.
DNA sample cleanup using deterministic lateral displacement (2016)

Optical mapping relies on the preparation of fluorescent DNA. DNA must be imaged with good signal to noise and therefore the background of unwanted DNA fragments, fluorescent dyes and other reagents need to be removed. We use deterministic lateral displacement to separate 48.5 kbp DNA from < 10 kbp DNA. We also show the removal of 48.5 kbp DNA fragments from a background of fluorescent ATTO647N molecules and the recovery of >50 kbp molecules from a background of shorter digested fragments. In both cases improving signal to noise during imaging.
Joint impulse response shortening for DMT transceivers (2002)

A new algorithm is proposed for joint impulse response shortening in full-duplex discrete multitone transceivers. In comparison with the previous approach, the proposed algorithm takes into account both the presence of noise and the flexibility of having different signal/noise power distributions.
All-in-One digital microfluidics pipeline for proteomic sample preparation and analysis (2023)

Highly sensitive and reproducible analysis of samples containing low amounts of protein is restricted by sample loss and the introduction of contaminants during processing. Here, we report an All-in-One digital microfluidic (DMF) pipeline for proteomic sample reduction, alkylation, digestion, isotopic labeling and analysis. The system features end-to-end automation, with integrated thermal control for digestion, optimized droplet additives for sample manipulation and analysis, and an automated interface to liquid chromatography with tandem mass spectrometry (HPLC-MS/MS). Dimethyl labeling was integrated into the pipeline to allow for relative quantification of the trace samples at the nanogram level, and the new pipeline was applied to evaluating cancer cell lines and cancer tissue samples. Several known proteins (including HSP90AB1, HSPB1, LDHA, ENO1, PGK1, KRT18, and AKR1C2) and pathways were observed between model breast cancer cell lines related to hormone response, cell metabolism, and cell morphology. Furthermore, differentially quantified proteins (such as PGS2, UGDH, ASPN, LUM, COEA1, and PRELP) were found in comparisons of healthy and cancer breast tissues, suggesting potential utility of the All-in-One pipeline for the emerging application of proteomic cancer sub-typing. In sum, the All-in-One pipeline represents a powerful new tool for automated proteome processing and analysis, with the potential to be useful for evaluating mass-limited samples for a wide range of applications.
917 Biomechanical property of soft tissue components and anterior disc displacement in temporomandibular joint: Individual finite element analysis (2001)

Temporomandibular joint (TMJ) disorder relates to the mechanical irregularity of the structual joint components, and the behevior of soft tissue components is considered as a key to understand the biomechanical condition in the TMJ. In this study, the attention has been focused on the stress and displacement of articular disc in disorderd TMJ with anterior disc displacement (ADD). ADD-TMJs have been modelled by using biplane MRI technique and the effect of ligamentizations of posterior connective tissue following to ADD has been examined by means of computational biomechanic analysis based on individual finite element modelling since the configulation of the joint components deeply depends on individual patients. As the result of a parameter study, it is found that the ligamentizations of the posterior connective tissue is contribute to the load redistribution in ADD-TMJ and considered as a biomechanical adaptation for ADD.
Secrecy without one-way functions (2013)

We show that some problems in information security can be solved without using one-way functions. The latter are usually regarded as a central concept of cryptography, but the very existence of one-way functions depends on difficult conjectures in complexity theory, most notably on the notorious "$P \ne NP$" conjecture. In this paper, we suggest protocols for secure computation of the sum, product, and some other functions, without using any one-way functions. A new input that we offer here is that, in contrast with other proposals, we conceal "intermediate results" of a computation. For example, when we compute the sum of $k$ numbers, only the final result is known to the parties; partial sums are not known to anybody. Other applications of our method include voting/rating over insecure channels and a rather elegant and efficient solution of Yao's "millionaires' problem". Then, while it is fairly obvious that a secure (bit) commitment between two parties is impossible without a one-way function, we show that it is possible if the number of parties is at least 3. We also show how our (bit) commitment scheme for 3 parties can be used to arrange an unconditionally secure (bit) commitment between just two parties if they use a "dummy" (e.g., a computer) as the third party. We explain how our concept of a "dummy" is different from a well-known concept of a "trusted third party". We also suggest a protocol, without using a one-way function, for "mental poker", i.e., a fair card dealing (and playing) over distance. We also propose a secret sharing scheme where an advantage over Shamir's and other known secret sharing schemes is that nobody, including the dealer, ends up knowing the shares owned by any particular player. It should be mentioned that computational cost of our protocols is negligible to the point that all of them can be executed without a computer.
H7N9 Influenza: What We Learned from H5N1 (2013)

During the past year, a second bird flu emerged in Asia—an avian influenza virus that is sporadically transmitted to humans. This virus of the H7N9 subtype proved lethal in 33% of the 135 cases reported as of October 2013, yet it is termed a “low-pathogenic” virus because of the mild to inapparent respiratory disease it causes in domestic poultry. In contrast, the H5N1 influenza virus that emerged in Southern China in 1997 is highly pathogenic to poultry, killing as many as 100% of the birds it infects. It, too, is sporadically transmitted to humans, and is lethal in about 60% of reported cases.
Delayless Subband Echo Cancellation (1997)

Echo suppression is a vital part of every communications system. The use of hands-free communication in cars, computer applications and video conferencing have created further demands for high-quality acoustic echo cancellation. In these applications the acoustic channel has, typically, a long impulse response in the order of 100 ms. Typical lengths of adaptive FIR-filters are 500-1500 taps, assuming a 12 kHz sampling frequency. In order to reduce the computational load and also to improve the convergence rate, sub-band processing schemes have been suggested. This paper presents a study of a delayless sub-band adaptive filter. The study shows a possible echo suppression of about 30 dB and also an improved convergence rate when compared to a fullband LMS-filter. The main issues discussed are filter bank design and a simple speech detector that gives a drastic performance improvement.
Embedding Equitable Design in the CS Computing Curricula (2022)

Computer science (CS) students' curricula is heavily focused on technical skills, and CS ethics, usability, equity, and people/society considerations are not well-integrated into the CS curriculum. If these topics are introduced, they are disconnected from the core courses. As a result, students do not learn to incorporate inclusive practices into their software designs. Thus, students create software through the perspective of a computer scientist - when the important perspective is that of the intended users. As a result, students entering the workforce are inclined to design software that is non-inclusive. We propose the integration of inclusive design in the undergraduate curriculum will result in students creating inclusive software. This research, based on the foundations of inclusive design methods, investigates a new approach to teaching CS. Inclusive software design is embedded into computing courses for all four years of the undergraduate CS curriculum. This new approach is "minimally invasive", occupying very little classroom time, instead it is integrated into the course work that is already assigned. With this work, we hope to answer the following questions: (1) Will this new approach improve students' ability to design inclusive software? (2) Will this approach create an inclusive climate among peers? (3) Will it affect student's success or lack thereof? (4) How and to what extent is this embedded inclusive design curriculum feasible to use?
Light emission mechanism of Lu/sub 2/(SiO/sub 4/)O:Ce (2003)

Two types of excitation and emission spectra with ultraviolet excitation are shown at 11 K for Lu/sub 2/(SiO/sub 4/)O:Ce (LSO). Since there are two crystallographically independent lutetium sites in LSO, the existence of two Ce activation centers (two-activation-center model) is proposed. The existence of two different decay time constants of the order of tens of nanoseconds, which are characteristic for fast Ce emission, are shown at 77 K. Although the temperature dependence of the decay time and the luminescence efficiency could not be measured for the Ce2, the fact that the gamma-ray-excited emission can be reconstructed from a weighted combination of the Ce1 and Ce2 emission spectra supports the two-activation-center model for LSO.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Development of Light Emitting Group IV Ternary Alloys on Si Platforms for Long Wavelength Optoelectronic Applications (2014)

This paper describes preparation of a new class of Ge1–x–ySixSny direct-gap semiconductors grown on Ge-buffered Si substrates via depositions of trigermane (Ge3H8), tetragermane (Ge4H0), tetrasilane (Si4H10), and stannane (SnD4) hydride precursors. These react at ultralow temperatures 320–290 °C to produce thick (∼500 nm) monocrystalline films with concentrations closely reflecting the gas phase molar ratio of the coreactants. A series of Ge-rich samples with a fixed 3–4% Si content and progressively increasing Sn content in the 4–10% range are grown to explore the possibility of obtaining direct gap materials for the first time in this semiconductor system. The resultant films also exhibit residual compressive strains that are largely relaxed via rapid thermal annealing between 550 and 700 °C depending on composition. These temperatures are 50–75 °C above the thermal decomposition threshold of Ge1–ySny/Ge materials with same Sn content, indicating that the ternaries are significantly more robust than the binary analogues. The compositional dependence of the strain relaxations is similar to that found for Ge1–xSix alloys grown directly on Si. Cross hatch patterns are formed on the surface of these materials as a consequence of interface misfit dislocations generated due to the mismatch with the underlying Ge buffer. The annealed films exhibit low defect densities and atomic scale chemical uniformity as indicated by STEM and element-selective EELS mapping, allowing a meaningful study of the optical properties as a function of Sn concentration. The results show that the separation of the direct and indirect edges can be made smaller than in Ge even for the non-negligible 3–4% Si content, confirming that with a suitable choice of Sn compositions the ternary Ge1–x–ySixSny reproduces all features of the electronic structure of the binary Ge1–ySny, including the sought after indirect-to-direct gap cross over. The alloys produced in this study represent an attractive alternative to Ge1–ySny for applications in IR optoelectronic technologies requiring high thermal budget processing and harsh operating conditions due to their enhanced thermal stability conferred by the incorporation of Si in the diamond-like structure.
Comprehensive Evaluation of Ureteral Healing After Electrosurgical Endopyelotomy in a Porcine Model: Original Report and Review of the Literature (2004)

Urothelium regenerated rapidly over an iatrogenic ureteral defect despite the absence of a lamina propria. Muscle cell coverage failed to occur completely at 8 weeks. In the initial 8 weeks of the healing process myofibroblasts appear to be prevalent. A persistent urinoma negatively impacts the healing process.
Hierarchical Silica Inverse Opals as a Catalyst Support for Asymmetric Molecular Heterogeneous Catalysis with Chiral Rh‐diene Complexes (2021)

Abstract The efficacy of heterogeneous catalysis relies heavily on diffusion and distribution of reactants within catalyst supports. However, the presence of confinement, essential for reaction selectivity, drastically slows down molecular transport. Here, macro‐mesoporous silica inverse opal (SiO 2 −IO) films were used as a model system to study the rather unexplored molecular infiltration behavior using a probe molecule resembling a catalyst via confocal laser scanning microscopy (CLSM). CLSM analysis revealed homogeneous tracer distribution in SiO 2 −IO and attachment to both transport and mesopores. Bulk macro‐mesoporous SiO 2 −IO support was used for the attachment of mono‐ and bis‐functionalized chiral Rh‐diene complexes, and the catalytic activity and selectivity with respect to the support was studied. Lower enantioselectivity was observed with the bis‐functionalized ligand due to ligand entanglement and reduced accessibility of the active site, while the mono‐functionalized ligand gave an excellent enantioselectivity of 94 % ee in the asymmetric 1,2‐addition of triphenylboroxine to N‐ tosylimines and could be recycled up to three times.
Silicon-on-insulator (SOI) integration for organic field effect transistor (OFET) based circuits (2011)

In this paper, we report the first silicon-on-insulator (SOI) integration technique for organic field effect transistor (OFET) based circuits. Proposed design flow relies on only basic micro-fabrication processes such as photolithography and physical vapor deposition. This novel fabrication technique allows patterning of conductive silicon gate islands on the subtrate and eases the via and interconnect patterning and deposition for a bottom-gate OFET configuration. We fabricated pand n-type transistors, and proof of concept OFET-based complementary circuits such as inverter and NAND-gate. Fabricated CMOS inverters have full rail-to-rail swing, very high gain (up to 58.3 at 60V, and 18.1 at 20V supply voltages), and outstanding noise margins of around 21V symmetric for NMhigh and NMlow at 60V supply voltage.
