Chronic Obstructive Pulmonary Disease in Farmers (2017)

Farming work was associated with greater risk of developing COPD. However, considering the several variables that may influence the disease prevalence in farmers, we suggest the adoption of a standardized research strategy.
The impact of technology on indexing (2000)

The indexing process has changed remarkably with technological advances. Indexing is no longer just ‘back-ofbook’ indexing, but includes automatic indexing, machine-aided indexing, web indexing and even 3-D indexing. Not all the effects have been positive, especially for the indexer, but the future of the Internet and efficient information retrieval lies with indexing.
Multiple estrogen receptor assays in human breast cancer. (1983)

A review of assay results from more than 6000 patients revealed 232 patients in whom multiple breast cancer specimens were analyzed for estrogen receptor (ER). All assays were performed in a single laboratory. Specimens were considered estrogen receptor positive (ER+) if the ER level was greater than 10 fmol/mg protein and estrogen receptor negative (ER-) if the ER level was less than 3. ER values between 3 and 10 fmol/mg protein were considered borderline. Simultaneous assays were performed in 58 patients with 3% major discordance (i.e., one assay ER- and one assay ER+). Major discordance for sequential biopsies was 19% (16 of 82) when the initial assay was ER+ and 13% (eight of 63) when the initial assay was ER-. (Apparent change from ER- to ER+ status was observed in five of nine patients with primary tumors less than 2 cm in diameter, suggesting that an inadequate amount of tissue may have been submitted for initial ER analysis.) There was no significant relationship between the time interval between sequential biopsies and the rate of discordance. Marked decreases in ER levels and 78% discordance were seen if rebiopsy was performed within 2 months of tamoxifen treatment. When these tamoxifen cases were excluded from the analysis, neither intervening endocrine therapy nor chemotherapy significantly altered discordance rates.
Multiple colonization defects in a cysteine protease mutant of Porphyromonas gingivalis (1997)

A cysteine protease mutant, G-102, of Porphyromonas gingivalis 381 defective in the rgp-1 gene has been recently constructed in this laboratory. In order to evaluate the role of the protease in the virulence properties of P. gingivalis, a number of putative periodontopathic properties of the mutant were evaluated. Relative to the parental strain, mutant G-102 was demonstrated to be defective in interacting with Gram-positive bacteria as well as cultured epithelial cells. In addition, the mutant was altered in attaching to the protein components of extracellular matrix as well as to type I collagen. Some of these alterations could result from the decreased autoaggregation displayed by mutant G-102 relative to strain 381. However, since the epithelial cell attachment assays were carried out at very low bacterial densities, it is unlikely that reduced autoaggregation of the mutant is responsible for its decreased ability to attach to these eucaryotic cells. Electron microscopic examination of the cells also revealed that mutant G-102 was altered in normal fimbrae expression. In addition, reduced expression of the 43 kDa fimbrial subunit in the mutant was detected with both Western and Northern blotting. These results indicated that the rgp-1 gene product can play either a direct or indirect role in the colonization properties of P. gingivalis.
The Case for Learned Index Structures (2018)

Indexes are models: a \btree-Index can be seen as a model to map a key to the position of a record within a sorted array, a Hash-Index as a model to map a key to a position of a record within an unsorted array, and a BitMap-Index as a model to indicate if a data record exists or not. In this exploratory research paper, we start from this premise and posit that all existing index structures can be replaced with other types of models, including deep-learning models, which we term \em learned indexes. We theoretically analyze under which conditions learned indexes outperform traditional index structures and describe the main challenges in designing learned index structures. Our initial results show that our learned indexes can have significant advantages over traditional indexes. More importantly, we believe that the idea of replacing core components of a data management system through learned models has far reaching implications for future systems designs and that this work provides just a glimpse of what might be possible.
Multimodal integration of voice and ink for pervasive computing (2003)

The acceptance of a standard VoiceXML format has facilitated the development of voice applications, and we anticipate a similar facilitation of pen application development upon the acceptance of a standard InkXML format. In this paper we present a multimodal interface architecture that combines standardized voice and ink formats to facilitate the creation of robust and efficient multimodal systems, particularly for noisy mobile environments. The platform provides a Web interactive system for generic multimodal application development. By providing mutual disambiguation of input signals and superior error handling this architecture should broaden the spectrum of users to the general population, including permanently and temporarily disabled users. Integration of VoiceXML and InkXML provides a standard data format to facilitate Web based development and content delivery. Diverse applications ranging from complex data entry and text editing applications to Web transactions can be implemented on this system, and we present a prototype platform and sample dialogues.

Simple Iron Catalyst for Terminal Alkene Epoxidation (2003)

[reaction: see text] A mu-oxo-iron(III) dimer, [((phen)(2)(H(2)O)Fe(III))(2)(mu-O)](ClO(4))(4), is an efficient epoxidation catalyst for a wide range of alkenes, including terminal alkenes, using peracetic acid as the oxidant. Low catalyst loadings, in situ catalyst preparation from common reagents, fast reaction times (<5 min at 0 degrees C), and enhanced reaction performance at high substrate concentrations combine to create a temporally and synthetically efficient procedure for alkene epoxidation.

The double scroll family (1986)

This paper provides a rigorous mathematical proof that the double scroll is indeed chaotic. Our approach is to derive a linearly equivalent class of piecewise-linear differential equations which includes the double scroll as a special case. A necessary and sufficient condition for two such piecewise-linear vector fields to be linearly equivalent is that their respective eigenvalues be a scaled version of each other. In the special case where they are identical, we have exact equivalence in the sense of linear conjugacy. An explicit normalform equation in the context of global bifurcation is derived and parametrized by their eigenvalues. Analytical expressions for various Poincaré maps are then derived and used to characterize the birth and the death of the double scroll, as well as to derive an approximate one-dimensional map in analytic form which is useful for further bifurcation analysis. In particular, the analytical expressions characterizing various half-return maps associated with the Poincaré map are used in a crucial way to prove the existence of a Shilnikov-type homoclinic orbit, thereby establishing rigorously the chaotic nature of the double scroll. These analytical expressions are also fundamental in our in-depth analysis of the birth (onset of the double scroll) and death (extinction of chaos) of the double scroll. The unifying theme throughout this paper is to analyze the double scroll system as an unfolding of a large family of piecewise-linear vector fields in <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R^3</tex> . Using this approach, we were able to prove that the chaotic dynamics of the double scroll is quite common, and is robust because the associated horseshoes predicted from Shilnikov's theorem are structurally stable. In fact, it is exhibited by a large family (in fact, infinitely many linearlyequivalent circuits) of vector fields whose associated piecewise-linear differential equations bear no resemblance to each other. It is therefore remarkable that the normalized eigenvalues, which is a local concept, completely determine the system's global qualitative behavior.
Mesenchymal Stem Cell Conditioned Media Ameliorate Psoriasis Vulgaris: A Case Study (2019)

Psoriasis, an autoimmune disease, affects a vast number of peoples around the world. In this report, we discuss our findings about a scalp psoriasis suffering patient with a Psoriasis Scalp Severity Index (PSSI) score of 28, who was treated with Mesenchymal stem cell conditioned media (MSC-CM). Remarkably, complete regression was recorded within a treatment period of one month only (PSSI score of 0). A number of bioactive factors like cytokines and growth factors secreted by MSCs in the conditioned medium are very likely to be the principle molecules which play a vital role in skin regeneration. Treatment using MSC-CM appears to be an effective tool for tackling the psoriatic problem and, thus, may offer a new avenue of therapy which could be considered as an alternative approach to overcome the limitations of the cell-based therapy.
Comparison of Antiwear Additive Response Among Several Base Oils of Different Polarities (1999)

The antiwear performance of tricresyl phosphate dissolved in 11 kinds of base oils of different polarities has been studied. A mineral oil (MO) and an alkylnaphthalene (AN) were used as non-or low-polarity base oils. Five polyol esters (POEs), i.e., three trimethylolpropane esters and two pentaerythritol esters, and four polyalkylene glycols (PAGs) were used as the high polarity base oils. A four-ball friction apparatus was used to determine the anti-wear performance, using commercially available bearing steel balls as test specimens. All the TCP-formulated base oils showed optimum concentration characteristics for minimizing wear. It is shown that the order of the optimum concentration for POEs and PAGs can be reasonably explained by the interaction between additive and base oils, by using their solubility parameters and molecular sizes. These oils' dielectric constants showed little correlation with optimum concentrations. The dielectric constant showed large effects on such non- or low-polarity oils as MO and AN. A good correlation of the optimum concentration for all the base oils was obtained when it was arranged as a function of (SPbase/SPTCP)14.2 (MWbase/MWTCP)−2.78 (ε)18.6.

A multi-threading architecture for multilevel secure transaction processing (2003)

A TCB and security kernel architecture for supporting multi-threaded, queue-driven transaction processing applications in a multilevel secure environment is presented. Our design exploits hardware security features of the Intel 80/spl times/86 processor family. Intel's CPU architecture provides hardware with two distinct descriptor tables. We use one of these in the usual way for process isolation. For each process, the descriptor table holds the descriptors of "system-low" segments, such as code segments, used by every thread in a process. We use the second table to hold descriptors for segments known to individual threads within the process. This allocation, together with an appropriately designed scheduling policy, permits us to avoid the full cost of process creation when only switching between threads of different security classes in the same process. Where large numbers of transactions are encountered on transaction queues, this approach has benefits over traditional multilevel systems.
Fast copy coalescing and live-range identification (2002)

This paper presents a fast new algorithm for modeling and reasoning about interferences for variables in a program without constructing an interference graph. It then describes how to use this information to minimize copy insertion for ϕ-node instantiation during the conversion of the static single assignment (SSA) form into the control-flow graph (CFG), effectively yielding a new, very fast copy coalescing and live-range identification algorithm.This paper proves some properties of the SSA form that enable construction of data structures to compute interference information for variables that are considered for folding. The asymptotic complexity of our SSA-to-CFG conversion algorithm is where-is the number of instructions in the program.Performing copy folding during the SSA-to-CFG conversion eliminates the need for a separate coalescing phase while simplifying the intermediate code. This may make graph-coloring register allocation more practical in just in time (JIT) and other time-critical compilers For example, Sun's Hotspot Server Compiler already employs a graph-coloring register allocator[10].This paper also presents an improvement to the classical interference-graph based coalescing optimization that shows adecrease in memory usage of up to three orders of magnitude and a decrease of a factor of two in compilation time, while providing the exact same results.We present experimental results that demonstrate that our algorithm is almost as precise (within one percent on average) as the improved interference-graph-based coalescing algorithm, while requiring three times less compilation time.

Parallel transmit and receive technology in high‐field magnetic resonance neuroimaging (2010)

Abstract The major radiofrequency engineering challenges of high‐field MR neuroimaging are as follows: (1) to produce a strong, homogeneous transmit B 1 field, while remaining within regulatory guidelines for tissue power deposition and (2) to receive the signal with the maximum signal‐to‐noise and the greatest flexibility in terms of utilizing the benefits of parallel imaging. Borrowing from developments in electromagnetic hyperthermia, the first challenge has been met by the use of transmit arrays, in which the input power to each element of the array can be varied in terms of magnitude and phase. Optimization of these parameters, as well as the form of the applied RF pulse, leads to very homogeneous B 1 fields throughout the brain. The design of large receive arrays, using impedance‐mismatched preamplifiers and geometrical overlap for interelement isolation, has resulted in significant sensitivity improvements as well as large acceleration factors in parallel imaging. © 2010 Wiley Periodicals, Inc.

The Pharmacokinetics of LMW Dermatan Sulphate: Long-Term Persistence of Intact Material (1993)

An iodinated derivative of the low molecular weight dermatan sulphate Desmin 370 was administered to rats by intravenous, subcutaneous and intramuscular routes in conjunction with unlabelled Desmin 370. Following intravenous injection radiolabel was cleared from the plasma according to a tri-exponential function with elimination half-lives of 45 min and 13 h; there was a high concentration in tissues, particularly the kidney, compared with plasma. The apparent bioavailability following s.c. injection was 52-65%, but 84-100% after i.m. administration. Undegraded as well as desulphated molecules were identified in plasma, and intact 125I-Desmin 370 comprised > 85% of the radiolabel in urine 48 h post-injection. Thus intact Desmin 370 persists for a long period after a single injection. The pharmacological significance of these findings, however, remains to be determined.
Local permutations of products of Bell states and entanglement distillation (2003)

We present different algorithms for mixed-state multicopy entanglement distillation for pairs of qubits. Our algorithms perform significantly better than the best-known algorithms. Better algorithms can be derived that are tuned for specific initial states. These algorithms are based on a characterization of the group of all locally realizable permutations of the ${4}^{n}$ possible tensor products of n Bell states.
Scalable and accurate identification of AS-level forwarding paths (2004)

Traceroute is used heavily by network operators and researchers to identify the IP forwarding path from a source to a destination. In practice, knowing the autonomous system (AS) associated with each hop in the path is also quite valuable. In previous work we showed that the IP-to-AS mapping extracted from BGP routing tables is not sufficient for determining the AS-level forwarding paths. By comparing BGP and traceroute AS paths from multiple vantage points, Z. Morley Mao et al. (2003) proposed heuristics that identify the root causes of the mismatches and fix the inaccurate IP-to-AS mappings. These heuristics, though effective, are labor-intensive and mostly ad hoc. This paper proposes a systematic way to construct accurate IP-to-AS mappings using dynamic programming and iterative improvement. Our algorithm reduces the initial mismatch ratio of 15% between BGP and traceroute AS paths to 5% while changing only 2.9% of the assignments in the initial IP-to-AS mappings. This is in contrast to the results of Z. Morley Mao et al. (2003), where 10% of the assignments were modified and the mismatch ratio was only reduced to 9%. We show that our algorithm is robust and can yield near-optimal results even when the initial mapping is corrupted or when the number of probing sources or destinations is reduced. Our work is a key step towards building a scalable and accurate AS-level traceroute tool
Evaluation of the optical fibre diameter analyser (OFDA) for measuring fiber diameter parameters of sheep and goats (1994)

The Optical Fibre Diameter Analyser (OFDA) instrument is based on automatic image analysis technology and was recently introduced to provide a rapid, accurate measurement of average fiber diameter (AFD) and diameter distribution (SD) of textile fibers. Experiments were conducted with wool and mohair in various physical forms (top, core, and staple) to compare results produced by the OFDA with two other methods of determining fiber diameter parameters: the standard projection microscope (PM) method as described by the American Society for Testing and Materials (ASTM) and the Peyer Texlab FDA 200 System (FDA200). The results show that the OFDA fiber diameter measurements were very closely related to PM measurements, and the OFDA partially overcame one shortcoming of the FDA200, overestimation of SD. The results suggest that the OFDA is a promising system for rapid and accurate evaluation of fiber diameter and its distribution.
