Clinical features of isolated Fallopian tube torsion: evidence from a large series (2022)

We aimed at studying isolated Fallopian tube torsion (IFTT) in a relatively large cohort of women and to evaluate different features of IFTT in comparison to a large cohort of women with non-IFTT adnexal torsion (NIAT). This was a retrospective cohort study. We included women with surgically confirmed ovarian and/or Fallopian tube torsion between March 2011 and June 2020. Fifty-four cases of IFTT were surgically confirmed during the study period and were compared to 422 surgically confirmed NIAT. The rate of controlled ovarian hyperstimulation treatments, current pregnancy, and vomiting was lower in the IFTT group compared with the NIAT group. Cervical tenderness and vaginal discharge were more common in the IFTT group. Oedematous and enlarged ovaries were less common in the IFTT group. In multivariate regression analysis, the following factors were independently associated with IFTT: (i) vaginal discharge [adjusted odds ratio (aOR) 95% CI 8.16, 1.98-33.55]; (ii) cervical motion tenderness (aOR 95% CI 2.71, 1.01-7.29); (iii) fertility treatments (aOR 95% CI 0.26, 0.70-0.77); (iv) previous abdominal surgery (aOR 95% CI 0.46, 0.22-0.96); (v) vomiting (aOR 95% CI 0.38, 0.19-0.76); and (vi) enlarged ovary (aOR 95% CI 0.34, 0.18-0.65). In conclusion, we have identified factors positively and negatively associated with IFTT in a large cohort of women with adnexal torsion.
Distributed Resource Allocation for Smart Matter Using Decentralized Analog Computation and Communication (1999)

Abstract The use of analog circuits implementing market allocation for potential control and coordination of large numbers of MEMS actuators, controllers, and/or sensors is investigated. While theoretical work has shown that markets can allocate actuation or control in a robust, flexible, and distributed fashion, this paper demonstrates that analog hardware implementation of the markets is promising for actuation allocation. Like human markets, the analog circuit implementations are robust against changes in actuator function or failures. The market wire offers rapid communication and coordination among large numbers of agents.
Overlay of WB-CDMA-FDD on WB-TD/CDMA-TDD, reverse link capacity assessment (2003)

A reverse link capacity estimation of a two-layered hierarchical cellular structure (HCS) is presented making use of different multiple access schemes (MAS) in each layer. The HCS under study consists of a macrocell layer which uses wide-band code division multiple access with frequency division duplex (WB-CDMA-FDD). This macrocell layer overlays a microcell layer which uses wide-band time division/code division multiple access with asymmetric time division duplex (WB-TD/CDMA-TDD). System capacity in Erl/carrier/cluster and spectrum efficiency in Kbit/s/MHz/cluster are assessed for three different circuit-switched services and two combinations of them. The impact of different channel allocation strategies (CAS) on the system capacity is also assessed. For this purpose, two different resource allocation strategies are considered in the microcell layer using the WB-TD/CDMA-TDD multiple access scheme (MAS); they are the classic fixed channel assignment (FCA) and a simple dynamic channel allocation (SDCA). For the macrocell layer, using WB-CDMA, only FCA is used, The capacity of this system is also compared with the capacity of a HCS using WB-TD/CDMA-TDD in both layers.

Constraint-based rule mining in large, dense databases (1999)

Constraint-based rule miners find all rules in a given dataset meeting user-specified constraints such as minimum support and confidence. We describe a new algorithm that directly exploits all user-specified constraints including minimum support, minimum confidence, and a new constraint that ensures every mined rule offers a predictive advantage over any of its simplifications. Our algorithm maintains efficiency even at low supports on data that is dense (e.g. relational data). Previous approaches such as Apriori and its variants exploit only the minimum support constraint, and as a result are ineffective on dense data date to a combinatorial explosion of "frequent itemsets".

Crystal Structures of Norfloxacin Hydrates (2008)

Two novel hydrate forms of norfloxacin (NF) were serendipitously obtained during cocrystallization with eugenol. NF 1.25 hydrate and 1.125 hydrate are isomorphous crystal structures in the P21/c space group, each with two symmetry-independent drug molecules, two full water molecules, and a third water of 0.5 and 0.25 partial occupancy, respectively. Water promoted proton transfer results in a shift from neutral to ionic hydrogen bonding between norfloxacin molecules in hydrate structures. The presence of eugenol additive gave novel NF hydrates of lower water stoichiometry, whereas crystallization in its absence gave the known NF dihydrate.
Influence of harvest time on citrus pectin and its in vitro inhibition of fibroblast growth factor signal transduction (2002)

Abstract Seasonal changes in pectin content and chemical composition were studied in three anatomical layers of ‘Rio Red’ grapefruit ( Citrus paradisi Macf), a currently popular cultivar in the Rio Grande Valley in Texas, USA. Fruits were harvested at intervals between August 1998 and May 1999. Pectin content in flavedo decreased throughout the season, while in albedo and segment membrane the pectin content was lowest in mid‐season (November and January). In all three layers the anhydrogalacturonic acid (AGA) content of pectin was highest in mid‐season. While the methoxyl content (MC) of pectin increased, the total neutral sugar (TNS) content of pectin decreased in all three layers throughout the season. The in vitro effect of grapefruit pectin on fibroblast growth factor (FGF)–FGF receptor (FGFR) interaction was also investigated. The strong interdependence of heparin on factor–receptor interaction provides means for identifying new antagonists of growth factor activity and thus for treatment of various diseases. Our results showed that grapefruit pectin significantly inhibited the binding of FGF‐1 to FGFR1 in the presence of 0.1 µg ml −1 heparin. Pectin of albedo from grapefruits harvested in January was the most potent inhibitor. The in vitro inhibitory activity was significantly correlated with the percentage of rhamnose. Kinetic studies revealed a competitive nature of pectin on FGF signal transduction with heparin. The observation that the biological activity of heparin can be antagonised by citrus pectin suggests that pectins should be investigated further as anti‐growth factor agents for potential health benefits. © 2002 Society of Chemical Industry
ELECTROMAGNETIC WAVE INSTABILITY IN A PLASMA WITH RELATIVISTIC PARTICLES IN A (1983)

A new mechanism, which accounts for the direct excitation of electromagnetic waves by relativistic particles moving in random magnetic fields, is considered. We are then able to study maser-type wave excitations by slightly anisotropic particle distribution functions as well as electromagnetic wave emissions in beam-plasma interactions The purpose of the present letter is to point out a new instability in a plasma with relativistic particles in a random magnetic field, and to show that high frequency electromagnetic waves can be excited. The largest generated frequencies are here not related to the particle energies e (cf. the case where particles (rest mass m) move in a rippled (wavelength 2n/ko) random magnetic field when O.)ma x ~ 2koce.Z/(mc2) 2 ) and our effect appears thus for arbitrarily large frequencies, although with decreasing growth rate (7o~ ~ 09-2). In the case of instability (7~o > 0) the wave is accordingly amplified if the plasma is optically thick at the corresponding frequency. In addition, the threshold of the instability we are going to mention does not depend on the frequency, which means that very high frequencies may be unstable. Random magnetic fields as well as relativistic particles are present in many space plasmas, and the plasma volumes are often so large that very high frequency electro- magnetic waves can be amplified. Thus we think that our effect can be of relevance for problems concerning the emission of electromagnetic waves by relativistic particles in space plasmas (Kaplan and Tsytovich, 1973). We shall show that even a very small anisotropy of the particle distribution function is sufficient for wave amplification. The cosmic ray electrons and ions are indeed always slightly anisotropicaUy distributed, due to particle diffusion in space. We shall here limit ourselves to the case where the energies of the particles are so large that the curvature of the particle motion in the random fields can be neglected, i.e. the characteristic lengths of the magnetic field inhomogeneities are much smaller than the Larmor radii.
Microstrip-Ridge Gap Waveguide–Study of Losses, Bends, and Transition to WR-15 (2014)

This paper presents the design of microstrip-ridge gap waveguide using via-holes in printed circuit boards, a solution for high-frequency circuits. The study includes how to define the numerical ports, pin sensitivity, losses, and also a comparison with performance of normal microstrip lines and inverted microstrip lines. The results are produced using commercially available electromagnetic simulators. A WR-15 to microstrip-ridge gap waveguide transition was also designed. The results are verified with measurements on microstrip-ridge gap waveguides with WR15 transitions at both ends.
Abnormal fibrillin-1 expression and chronic oxidative stress mediate endothelial mesenchymal transition in a murine model of systemic sclerosis (2010)

Systemic sclerosis (SSc) is an autoimmune connective tissue disorder characterized by oxidative stress, impaired vascular function, and attenuated angiogenesis. The tight-skin (Tsk(-/+)) mouse is a model of SSc that displays many of the cellular features of the clinical disease. We tested the hypotheses that abnormal fibrillin-1 expression and chronic phospholipid oxidation occur in Tsk(-/+) mice and, furthermore, that these factors precipitate a prooxidant state, collagen-related protein expression, apoptosis, and mesenchymal transition in endothelial cells cultured on Tsk(-/+) extracellular matrix. Human umbilical vein endothelial cells were seeded on microfibrils isolated from skin of C57BL/6J (control) and Tsk(-/+) mice in the presence or absence of chronic pretreatment with the apolipoprotein Apo A-I mimetic D-4F (1 mg·kg(-1)·day(-1) ip for 6 to 8 wk). Nitric oxide-to-superoxide anion ratio was assessed 12 h after culture, and cell proliferation, apoptosis, and phenotype were studied 72 h after culture. Tsk(-/+) mice demonstrated abnormal "big fibrillin" expression (405 kDa) by Western blot analysis compared with control. Endothelial cells cultured on microfibrils prepared from Tsk(-/+) mice demonstrated reduced proliferation, a prooxidant state (reduced nitric oxide-to-superoxide anion ratio), increased apoptosis, and collagen-related protein expression associated with mesenchymal transition. Chronic D-4F pretreatment of Tsk(-/+) mice attenuated many of these adverse effects. The findings demonstrate that abnormal fibrillin-1 expression and chronic oxidative stress mediate endothelial mesenchymal transition in Tsk(-/+) mice. This mesenchymal transition may contribute to the reduction in angiogenesis that is known to occur in this model of SSc.

Genome-wide multilocus analysis of intraspecific differentiation in Oryza rufipogon Griff. from China and the influence of introgression from O. sativa L. (2013)

Twenty-five populations of Oryza rufipogon from China and 144 cultivars of Oryza sativa were selected for this study. Based on the DNA fragment of Ehd1-4 and subspecies-specific sequence-tagged site markers in different chromosomes, intraspecific differentiation in O. rufipogon from China was analyzed. The introgression from O. sativa to O. rufipogon was also analyzed based on simple sequence repeat markers. The results revealed that the DNA fragment of Ehd1-4 could distinguish the O. sativa subspecies japonica and indica. Furthermore, although significant indica-japonica differentiation did not occur in most O. rufipogon populations from China, O. rufipogon varieties from Hainan Island and from the mainland of China showed differentiation tendencies. Japonica-like O. rufipogon varieties were predominant in Mainland China. However, more indica-like O. rufipogon varieties were found in Hainan Island. Finally, although cultivar-specific alleles were found in most of the O. rufipogon varieties from Hainan Island and Guangdong Province, some varieties remain pure and non-introgressive.
Portable maintenance aid instrument pack (PIP) (2002)

Flight line component false removals are costly and add to the logistics tail of every weapon system. VXI offers opportunity to consolidate test needs into a user-friendly application that can significantly reduce flight line false removal rates. VXI has grown substantially in applications from testing in the lab to field support of weapon systems. Early criticism of VXI came that it was only intended for lab or depot environments. Recently, developers have been taking on the challenge of extending VXI use into field environments. This paper addresses false removals, describes a VXI test system approach, and describes the challenges of creating an enclosure for COTS VXI instruments that protect them from very harsh flight-line environmental extremes. This effort was accomplished for the RAH-66 Comanche Helicopter program, and has created two working prototypes.
ASTM Reformulated Gasoline Standards for a Clean Environment (1993)

ASTM has a 90-year history of providing an open forum for representatives from industry, government, academia, and the general-interest sector to develop high-quality, voluntary consensus standards. At this time, there is an urgent need for ASTM Committee D-2 on Petroleum Products and Lubricants to develop standards for automobile gasolines reformulated to reduce emissions, along with new methods to measure fuel composition and properties rapidly and with good precision. The result will be ASTM fuel standards for cleaner air.
[Risk factors of pneumothorax and hemorrhage in lung biopsy: a single institution experience]. (2012)

Transthoracic lung biopsy is a minimally invasive technique. However, the presence of associated risk factors must lead to consider another diagnostic method.
Adopting oculopressure tonometry as a transient in vivo rabbit glaucoma model (2015)

Abstract Glaucoma represents a group of eye disorders partly related to raised intraocular pressure (IOP) leading to progressive optic nerve damage resulting in impaired vision and possibly blindness. To assess the suitability of new IOP lowering therapeutic strategies, such as the implantation of glaucoma drainage devices, appropriate animal models have to be used. Currently, a number of rodent glaucoma models are available [1], however, especially for surgical interventions rodent eyes are too small. Rabbits are much more suitable with respect to dimension. Unfortunately, rabbit glaucoma model systems described in literature are difficult to reproduce or fail totally, associated with a high level of discomfort and pain for treated animals. Therefore, development of an in vivo rabbit glaucoma model is one of the most important goals in glaucoma research. Here, we describe the adaptation of the oculopressure tonometry, an existing method to quantify the outflow of aqueous humor in humans, to generate a transient glaucoma model in rabbits. The existing suction-cup oculopressor (SCOP) is extended with newly designed suction-cups, which are adjusted to the anatomy of the rabbit eye. The modification of the oculopressure tonometry method facilitates an increase in IOP over a time frame of 9 minutes by vacuum induced deformation of the rabbit eye. This method can be used to test functionality of fistulating glaucoma surgeries or implanted drainage devices in a long term follow-up without any side effects and suffering of the animals.
A library of ATTR amyloidosis patient-specific induced pluripotent stem cells for disease modelling and in vitro testing of novel therapeutics (2018)

Hereditary transthyretin amyloidosis (ATTR amyloidosis) is an autosomal dominant protein-folding disorder caused by over 100 distinct mutations in the transthyretin (TTR) gene. In ATTR amyloidosis, protein secreted from the liver aggregates and forms amyloid fibrils in downstream target organs, chiefly the heart and peripheral nervous system. Few animal models of ATTR amyloidosis exist and none recapitulate the multisystem complexity and clinical variability associated with disease pathogenesis in patients. Induced pluripotent stem cells (iPSCs) stand to revolutionize the way we study human development, model disease, and perhaps treat patients afflicted with highly variable multisystem diseases such as ATTR amyloidosis. Here, we fully characterize six representative iPSC lines from a library of previously reprogrammed iPSC lines and reprogrammable blood samples derived from ATTR amyloidosis patients. This unique resource, described herein, can be harnessed to study diverse disorder.
VEHICLE LATERAL CONTROL AND SWITCHING. VOLUME II. DESIGN AND ANALYSIS. PART A. VLACS MODELS (1980)

This report contains design and analysis results from UMTA's Vehicle Lateral Control and Switching (VLACS) Project of the Automated Guideway Transit Technology (AGTT) Program. The objective of the VLACS project is to develop lateral control and switching systems which will reduce the cost and improve the performance of these systems on automated transit vehicles. The VLACS project tasks include a review of existing lateral control and switching technology, detailed mathematical modeling, analysis, simulation, detailed hardware studies, experimentation with alternative designs, and development of guideline specifications for VLACS systems. In this report, lateral control system models are developed for wire-follower, wall-follower active, and wall-follower passive lateral control systems, including the vehicle, lateral position sensors, and actuators. Vehicle dynamic models are developed for vehicles having Ackermann steering geometry and for vehicles with wagon-wheel steering. AGT vehicle models developed include ten-degree-of-freedom models used for ride quality analysis and simpler three-degree-of-freedom models used for lateral control system design and analysis. Part A of this report contains a description of VLACS model development.
Growth of Si on Si(100) via H/Cl exchange and the effect of interfacial boron (1992)

Using alternating exposures of Si2H6 and Si2Cl6, very thin Si layers have been grown on the Si(100) surface at temperatures (T) as low as 475 °C. Although this growth method is not truly self-limiting, some of the desired features for Si atomic layer epitaxy (ALE) are retained, as discussed here. The growth rate of new Si on Si(100) using this method is limited by the thermal desorption of H2 and HCl. Doping the surface with boron atoms can lower the growth temperature, due to a weakening of the Si—H and Si—Cl bonds on the surface as observed in the temperature programmed desorption results from H2, HCl, and SiCl2 desorption from the clean and the boron-doped Si(100) surfaces.
Automatic Opinion Polarity Classification of Movie Reviews (2004)

One approach to assessing overall opinion polarity (OvOP) of reviews, a concept defined in this paper, is the use of supervised machine learning mechanisms. In this paper, the impact of lexical filtering, applied to reviews, on the accuracy of two statistical classifiers (Naive Bayes and Markov Model) with respect to OvOP identification is observed. Two kinds of lexical filters, one based on hypernymy as provided by WordNet (Fellbaum, 1998), and one hand-crafted filter based on part-of-speech (POS) tags, are evaluated. A ranking criterion based on a function of the probability of having positive or negative polarity is introduced and verified as being capable of achieving 100% accuracy with 10% recall. Movie reviews are used for training and evaluation of each statistical classifier, achieving 80% accuracy.
EsteMate: a tool for automated power and area estimation in analog top-down design and synthesis (2002)

A novel methodology to derive power and area is presented. The method consists of the generation of a training set and a subsequent training of an Artificial Neural Network. The resulting estimators do not only predict power and area accurately and efficiently, they also reflect the complex interaction between different specifications. The method has been implemented in a tool, EsteMate, and is illustrated with practical examples.
Online Algorithms with Discrete Visibility - Exploring Unknown Polygonal Environments (2008)

The context of this work is the exploration of unknown polygonal environments with obstacles. Both the outer boundary and the boundaries of obstacles are piecewise linear. The boundaries can be nonconvex. The exploration problem can be motivated by the following application. Imagine that a robot has to explore the interior of a collapsed building, which has crumbled due to an earthquake, to search for human survivors. It is clearly impossible to have a knowledge of the building's interior geometry prior to the exploration. Thus, the robot must be able to see, with its onboard vision sensors, all points in the building's interior while following its exploration path. In this way, no potential survivors will be missed by the exploring robot. The exploratory path must clearly reflect the topology of the free space, and, therefore, such exploratory paths can be used to guide future robot excursions (such as would arise in our example from a rescue operation).
