Squamous Cell Carcinoma Arising in a Mature Cystic Teratoma

Introduction. Malignant transformation in a mature cystic teratoma of the ovary is a rare complication. Squamous cell carcinoma is the most common transformation. We describe a new case of squamous cell carcinoma arising in a mature cystic teratoma. Case Report. A premenopausal 52-year-old female patient is diagnosed with vaginal bleeding. According to examination made on the women and the pelvic scanning, 7 cm mass is found on the right adnexa of the patient. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic lymph node dissection, and debulking were the treatments completed on the patient. According to histopathological diagnosis, squamous cell carcinoma arising in a mature cystic teratoma is diagnosed as a reason for the mass in the right adnexa of the patient. Conclusion. The prognosis of the malign transformation of MCT depends on surgery stage; however it is extremely poor. The patient should receive chemotherapy regardless of stage. We have decided to administer second cycle carboplatin and paclitaxel treatments on the patient.
Modified Doherty power amplifier based on asymmetrical load matching networks

A novel deep back-off Doherty power amplifier based on asymmetrical load matching networks is proposed in this paper. The asymmetric Doherty power amplifier (ADPA) modulates carrier power amplifier (PA)'s load impedance in peak output power region. With the optimized matching method and modulation mode, the ADPA achieves optimum efficiency across the whole output back-off (OBO) power region. Due to the novel asymmetric load matching networks, the structure of output power combiner also gets simplified. The enhanced performance is implemented by the ADPA built with CREE's GaN HEMT CGH40010 and CGH40025 devices at 2.6GHz. Measurement results show the proposed ADPA can achieve 55.3% power added efficiency (PAE) at 9.2dB back-off power level and a favorable ACPR of-53.7dBc.
Physical and degradation properties of PLGA scaffolds fabricated by salt fusion technique

Tissue engineering scaffolds require a controlled pore size and interconnected pore structures to support the host tissue growth. In the present study, three dimensional (3D) hybrid scaffolds of poly lactic acid (PLA) and poly glycolic acid (PGA) were fabricated using solvent casting/particulate leaching. In this case, partially fused NaCl particles were used as porogen (200-300µ) to improve the overall porosity (≥90%) and internal texture of scaffolds. Differential scanning calorimeter (DSC) analysis of these porous scaffolds revealed a gradual reduction in glass transition temperature (Tg) (from 48°C to 42.5°C) with increase in hydrophilic PGA content. The potential applications of these scaffolds as implants were further tested for their biocompatibility and biodegradability in four simulated body fluid (SBF) types in vitro. Whereas, simulated body fluid (SBF) Type1 with the optimal amount of HCO3− ions was found to be more appropriate and sensible for testing the bioactivity of scaffolds. Among three combinations of polymer scaffolds, sample B with a ratio of 75:25 of PLA: PGA showed greater stability in body fluids (pH 7.2) with an optimum degradation rate (9% to 12% approx). X-ray diffractogram also confirmed a thin layer of hydroxyapatite deposition over sample B with all SBF types in vitro.
CS 364 B : Frontiers in Mechanism Design Lecture # 11 : Undominated Implementations and the Shrinking Auction ∗

Part I of the course focused on special cases where we can achieve all three properties — gross substitutes (GS) valuations and special cases thereof. In Part II of the course, we focused on more general valuation classes in which the exact version of the second property is already incompatible with the third (assuming P 6= NP ). We focused further on special cases where, ignoring incentive constraints, a constant-factor approximation to the optimal welfare can be computed in polynomial time. We’ve seem some pleasing positive results: when there is a logarithmic supply of every item or with coverage valuations, we designed MIDR allocation rules (and hence DSIC mechanisms) that have best-possible approximation guarantees (assuming P 6= NP ), albeit through quite complex designs.

Let’s recall the technical fine print. The result for logarithmic supply assumes that each bidder only wants one copy of each item and that the valuations are given as black boxes that support demand queries. The approximation guarantee is (1− ) provided the supply is at least c −2 logm for some (modest) constant c. The approximation guarantee for coverage valuations is 1− 1e ≈ 0.63. This guarantee extends to valuations that are convex combinations of gross substitutes valuations, assuming that such valuations are given as black boxes that support a randomized version of a value oracle.
Construct: in search of a theory of meaning

CONSTRUCT is a question-answering system for elementary mathematical language using natural language input. The primary goal of the system is to reach a better understandJng of the relationship between the syntactic and semantic components of natural language. The meaning conditions for sentences are given in terms of i:OI'lstructive set theory. The notion of a semantic transformation is introduced, and it is suggested how to analyze this notion in terms of program schemata. $ Athowledgements.

Positioning RFID Technology Into The Innovation Theory Landscape: A Multidimensional Perspective Integrating Case Study Approach

The main objective of this paper is to analyze RFID technology as an innovation concept through the lens of the diffusion of innovation theory. Drawing on the extant literature on the diffusion of innovations –with an emphasis on innovation classifications and the “open innovation”–, as well as on an analysis of a longitudinal case study conducted in a Canadian beverage supply chain currently exploring the potential of RFID technology, this research study suggests that RFID technology is a multidimensional concept than encompasses the traditional classifications of innovations (e.g., technological and organizational innovation, product and process innovation, incremental and radical innovation, interactive innovation) and emerging classifications such as open innovation. Therefore, any study on the assessment of the impact of RFID-enabled supply chain optimization should be aware of the locus of interest of each supply chain stakeholder with regard to RFID technology in order to better capture the network effect associated with the technology.
JPEG standard uniform quantization error modeling with applications to sequential and progressive operation modes

In this paper we propose a method for computing JPEG quantization matrices for a given mean-square error (MSE) or peak signal-to-noise ratio (PSNR). Then, we employ our method to compute JPEG standard progressive operation mode definition scripts using a quantization approach. Therefore, it is no longer necessary to use a trial and error procedure to obtain a desired PSNR and/or definition script, reducing cost. First, we establish a relationship between a Laplacian source and its uniform quantization error. We apply this model to the coefficients obtained in the discrete cosine transform stage of the JPEG standard. Then, an image may be compressed using the JPEG standard under a global MSE (or PSNR) constraint and a set of local constraints determined by the JPEG standard and visual criteria. Second, we study the JPEG standard progressive operation mode from a quantization-based approach. A relationship between the measured image quality at a given stage of the coding process and a quantization matrix is found. Thus, the definition script construction problem can be reduced to a quantization problem. Simulations show that our method generates better quantization matrices than the classical method based on scaling the JPEG default quantization matrix. The estimation of PSNR has usually an error smaller than 1 dB. This figure decreases for high PSNR values. Definition scripts may be generated avoiding an excessive number of stages and removing small stages that do not contribute during the decoding process with a noticeable image quality improvement. © 2001 SPIE and IS&T.

“Nino” man-in-the-middle attack on bluetooth secure simple pairing

As an interconnection technology, Bluetooth has to address all traditional security problems, well known from the distributed networks. Moreover, as Bluetooth networks are formed by the radio links, there are also additional security aspects whose impact is yet not well understood. In this paper, we describe a new man-in-the-middle (MITM) attack on Bluetooth secure simple pairing. The attack is based on the falsification of information sent during the input/output capabilities exchange. In addition, we propose countermeasures that render the attack impractical, although not totally eliminating its potential danger.
The MultiLoop programming construct

This paper introduces a new high-level parallel programming construct called multiLoop that is designed to extend existing imperative languages such as C and Java. A multiLoop statement translates to SPMD specification of a named group of synchronous-iterative processes. For efficient iterative communication, multiLoop provides a new publish/subscribe model of shared variable access. Under this model the sequential consistency of shared memory is maintained by a new, simple and efficient adaptation of virtual time paradigm. Virtual time is a localised message tagging and queuing procedure that provides a highly efficient alternative to barrier calls. ML-C, a prototype implementation based on C has been developed. We describe the programming model, discuss its implementation and present some empirical data showing good performance obtained for an example of the target class of applications.
The neural control of speech: From computational modeling to neural prosthesis

Speech production is a complex sensorimotor task involving tightly coordinated processing in the frontal, temporal, and parietal lobes of the cerebral cortex. To better understand these processes, our laboratory has designed, experimentally tested, and iteratively refined a neural network model whose components correspond to the brain regions involved in speech. The model’s components correspond to neural populations and are given precise anatomical locations. This allows activity in the model’s neurons to be compared directly to neuroimaging data. Computer simulations of the model account for a wide range of experimental findings, including data on acquisition of speaking skills, articulatory kinematics, and brain activity during normal and perturbed speech. The model is also being used to investigate communication disorders, including stuttering, apraxia of speech, and spasmodic dysphonia. The model has also been used to guide development of a brain-computer interface aimed at restoring speech output to an individual suffering from locked-in syndrome.
The History of the Concept of Transaction Costs: Neglected Aspects

According to the folk history of transaction costs, the concept is due to a seminal article by Ronald H. Coase, written in the 1930s. Failing to provide an operational framework, Coase's article was neglected for a long time, or so the story continues. In the 1970s, after the limits of the Arrow-Debreu paradigm had become obvious, several authors, including Oliver E. Williamson, Kenneth J. Arrow, Armen A. Alchian, and Harold Demsetz, took up the notion of transaction costs and turned it into a useful analytical tool. Partly responsible for this sudden upsurge of interest was an article by Coase in which he allegedly proposed the now famous “Coase Theorem. ”
Content Based Image Retrieval Sketches

question By Example (QBE) permits the tip user specify associate example as input for the search mechanism. With reference to digital image process, CBIR (Content based mostly Image Retrieval) lets users specify associate example image and retrieve pictures that match the options of given image. This development is understood as CBIR and therefore the main analysis space within the field of digital image process. Most of the applications depend upon annotations related to pictures whereas finding out them. The performance of such systems isn't satisfactory. The aim of CBIR is to retrieve pictures supported the image color, form and texture. This paper aims at presenting the varied issues and challenges that area unit associated with building a CBIR system that's supported the blank check sketch. Describe doable answer with the assistance of existing strategies to style and implement task orientating descriptors. This helps in filling the gap between the sketch image and additionally real time image. Experimental results on databases reveal that sketch based mostly pictures enable associate intuitive access to look applications. The SBIR technology are often utilized in several applications like crime bar, digital libraries, image sharing etc. Such system is extremely helpful because it will sight criminals and anti social components. start methodology is employed for the image process. A example application is constructed to demonstrate the potency of the projected application. The empirical results discovered that the projected application is helpful and might be utilized in real time applications.
Testing the Universal Structured Jet Models of Gamma-Ray Bursts with BATSE Observations

Assuming that the observed gamma-ray burst (GRB) rate as a function of redshift is proportional to the corrected star formation rate, we derive the empirical distribution of the viewing angles of long BATSE GRBs, Pem(θ), and the distribution of these bursts in the (θ, z)-plane, Pem(θ, z), by using a tight correlation between the collimation-corrected gamma-ray energy (Eγ) and the peak energy of the νFν spectrum measured in the rest frame (E). Our results show that Pem(θ) is well fitted by a lognormal distribution centered at log = -0.76 with a width of σlog θ = 0.57. We test different universal structured jet models by comparing model predictions, Pth(θ) and Pth(θ, z), with our empirical results. To make the comparisons reasonable, an "effective" threshold, which corresponds to the sample selection criteria of the long GRB sample, is used. We find that (1) Pth(θ) predicted by a power-law jet model is consistent with Pem(θ), but Pth(θ, z) predicted by this model is significantly different from Pem(θ, z); (2) Pth(θ, z) predicted by a single-Gaussian jet model is more consistent with Pem(θ, z) than that predicted by the power-law jet model, but Pth(θ) predicted by this model rapidly drops at θ > 0.3 rad and greatly deviates from Pem(θ); and (3) both the Pth(θ) and Pth(θ, z) predicted by a two-Gaussian jet model are roughly consistent with our empirical results. A brief discussion shows that cosmological effects on the Eγ-E relation do not significantly affect our results, but sample selection effects on this relationship might significantly influence our results.
Topology and geometry of cohomology jump loci

We elucidate the key role played by formality in the theory of characteristic and resonance varieties. We define relative characteristic and resonance varieties, V_k and R_k, related to twisted group cohomology with coefficients of arbitrary rank. We show that the germs at the origin of V_k and R_k are analytically isomorphic, if the group is 1-formal; in particular, the tangent cone to V_k at 1 equals R_k. These new obstructions to 1-formality lead to a striking rationality property of the usual resonance varieties. A detailed analysis of the irreducible components of the tangent cone at 1 to the first characteristic variety yields powerful obstructions to realizing a finitely presented group as the fundamental group of a smooth, complex quasi-projective algebraic variety. This sheds new light on a classical problem of J.-P. Serre. Applications to arrangements, configuration spaces, coproducts of groups, and Artin groups are given.
The Influences of Information Technology Organizational Performance in Higher Education

Higher education administrators are continually trying to control the costs of Information Technology (IT) investments and demonstrate the value of IT to the organization. As many administrators implement structures and processes, it is important to understand the impact of these on IT performance. Using a national sample of Chief Information Officers (CIOs) and high-level administrators, this study of higher education institutions examines the influences of IT performance. This research study examines the impact of IT governance, decision-making location, alignment of priorities, communication, and organizational strategy. As part of this research study, measures of organizational performance were developed to measure CIO perceptions of performance. As a result, this study provides a general profile of top performing IT organizations at higher education institutions.

Evidence that the immunity protein inactivates colicin 5 immediately prior to the formation of the transmembrane channel

Determination and analysis of the nucleotide sequences of the activity, immunity, and lysis genes of colicin 5 assigned colicin 5 to the subclass of pore-forming colicins to which colicins 10, E1, Ia, Ib, and K belong. Mutational analysis of colicin 5 and exchange of DNA fragments between the most closely related colicins, colicins 5 and 10, and between their immunity proteins localized the regions that determine the reaction specificity between colicin 5 and its immunity protein to residues 405 to 424 of colicin 5, the region corresponding to the amphiphilic alpha-helix 6 of the similar colicins E1 and Ia. The specificity-conferring residues 55 to 58 and 68 to 75 of the immunity protein were localized in the cytoplasmic loop and the inner leaflet of the cytoplasmic membrane. The localization of the reactive regions of the immunity protein and the colicin close to the inner side of the cytoplasmic membrane suggests that the immunity protein inactivates colicin 5 shortly before the lethal colicin pores in the cytoplasmic membrane are opened.
Abscisic Acid (ABA) Regulation of Arabidopsis SR Protein Gene Expression

Serine/arginine-rich (SR) proteins are major modulators of alternative splicing, a key generator of proteomic diversity and flexible means of regulating gene expression likely to be crucial in plant environmental responses. Indeed, mounting evidence implicates splicing factors in signal transduction of the abscisic acid (ABA) phytohormone, which plays pivotal roles in the response to various abiotic stresses. Using real-time RT-qPCR, we analyzed total steady-state transcript levels of the 18 SR and two SR-like genes from Arabidopsis thaliana in seedlings treated with ABA and in genetic backgrounds with altered expression of the ABA-biosynthesis ABA2 and the ABA-signaling ABI1 and ABI4 genes. We also searched for ABA-responsive cis elements in the upstream regions of the 20 genes. We found that members of the plant-specific SC35-Like (SCL) Arabidopsis SR protein subfamily are distinctively responsive to exogenous ABA, while the expression of seven SR and SR-related genes is affected by alterations in key components of the ABA pathway. Finally, despite pervasiveness of established ABA-responsive promoter elements in Arabidopsis SR and SR-like genes, their expression is likely governed by additional, yet unidentified cis-acting elements. Overall, this study pinpoints SR34, SR34b, SCL30a, SCL28, SCL33, RS40, SR45 and SR45a as promising candidates for involvement in ABA-mediated stress responses.
A two-sided academic landscape: portrait of highly-cited documents in Google Scholar (1950-2013)

The main objective of this paper is to identify and define the core characteristics of the set of highly-cited documents in Google Scholar (document types, language, free availability, sources, and number of versions), on the hypothesis that the wide coverage of this search engine may provide a different portrait of these documents with respect to that offered by traditional bibliographic databases. To do this, a query per year was carried out from 1950 to 2013 identifying the top 1,000 documents retrieved from Google Scholar and obtaining a final sample of 64,000 documents, of which 40% provided a free link to full-text. The results obtained show that the average highly-cited document is a journal or book article (62% of the top 1% most cited documents of the sample), written in English (92.5% of all documents) and available online in PDF format (86.0% of all documents). Yet, the existence of errors should be noted, especially when detecting duplicates and linking citations properly. Nonetheless, the fact that the study focused on highly cited papers minimizes the effects of these limitations. Given the high presence of books and, to a lesser extent, of other document types (such as proceedings or reports), the present research concludes that the Google Scholar data offer an original and different vision of the most influential academic documents (measured from the perspective of their citation count), a set composed not only of strictly scientific material (journal articles) but also of academic material in its broadest sense.
