Furthermore, it studies the particulars of the changes that ensued during the methods and internship involvement. Data from the drawings reveal pre-service teachers’ perceptions of their professional year. Qualitative analysis suggest the pre-service teachers in this study feel stress and anxiety entering the semester and leave with a sense of accomplishment and pride.
How Frequent does Bow and Arrow Sign Locate Ileocecal Valve during Colonoscopy?

Abstract Aim: Two major ways to locate the ileocecal valve (ICV) are to look for a thickening or bulge on the ileocecal fold, and the other is the “bow and arrow” method or the “appendix trick”. The aim of this study was to determine the accuracy of “bow and arrow” method to locate the ICV during colonoscopy. Patients and Methods: Colonoscopy was performed with the patients in the left lateral position. After cecal intubation had been confirmed, the appendiceal opening was identified, with the curve serving as the bow, an imaginary arrow was placed across the curve toward the appendix lumen. The tip of the imaginary arrow was then followed to confirm if it correlated to the location of the ICV. Results: The “bow and arrow” accurately located the ICV in 105 (76.6%) patients, but failed in 32 (23.4%) patients. The mean age (56.2 ± 13.1 years) of the patients in whom the “bow and arrow” located the ICV was lower than that (62.7 ± 0.9 years) of the patients in whom it failed to locate the ICV. Males, 58 (71.6%) had positive “bow and arrow”, while this was observed in 47 (83.9%) females. It correctly located the ICV in 73 (53.3%) of those with thin‑lip ICV, 20 (14.6%) of those with volcanic type, and 12 (8.8%) of those with double bulge ICV. Conclusion: The bow and arrow sign could not locate the ICV in all cases in our practice and so where it failed, alternative method should be employed to locate the ICV.
Integrated Gallium Phosphide Photonics

The integration of new materials mediating light-matter interaction in nanoscale devices is a persistent goal in nanophotonics. One of these materials is Gallium phosphide, which offers an attractive combination of a high refractive index (n=3.05 at λ = 1550 nm) and a large bandgap (Eg =2.26 eV), enabling photonic devices with strongly confined light fields, not suffering from heating due to two-photon absorption at telecommunication wavelengths. Furthermore, due to its non-centrosymmetric crystal structure, it has a non-vanishing secondorder susceptibility χ(2) and is piezoelectric. Related to its large refractive index is a high third-order susceptibility χ(3). Prior to this work the use of GaP for photonic devices was limited to individual non-integrated components, as GaP was not available on a substrate with substantially lower refractive index equivalent to SOI-wafers for silicon. In this work a process was developed that allows the integration of GaP devices onto SiO2. It exploits direct wafer bonding of a GaP/AlxGa1−xP/GaP heterostructure onto a SiO2-on-Si wafer. After substrate removal, photonic devices are patterned by dry-etching in the top GaP device layer. The GaP devices investigated here are used to explore nonlinear optics and optomechanics. In the area of nonlinear optics, secondand third-harmonic generation are observed. The Kerr coefficient is experimentally estimated as n2[1550nm] = 1.2(5)×10−17m2/W, for the first time in a precision measurement at telecommunication wavelengths. Four-wave mixing is used for broadband frequency comb generation, where a power threshold as low as 3 mW is obtained. The combination of four-wave mixing and second-harmonic generation leads to frequency-doubled combs. The optomechanical properties of GaP one-dimensional photonic crystal cavities are optimized by simulations and fabricated devices are characterized. Optical quality factors of Qo > 1×105 and optomechanical coupling strengths of g0/2π≈ 400 kHz are measured. Dynamical backaction in the form of the spring effect and the parametric amplification are observed, as well as optomechanically induced transparency and absorption. A device design for a microwave-to-optical transducer is developed, relying on the piezoelectricity of GaP. It combines electromechanical and optomechanical transduction. The predicted electromechanical coupling strength is in the MHz range. Furthermore, photonic crystal cavity designs containing a slot at the center of the cavity are studied. According to simulations for slot widths below 30 nm, optomechanical coupling strengths g0/2π> 1 MHz could be achieved. Fabricated silicon photonic crystal cavities show high quality factors of Qo ≈ 8×104 while hosting a mechanical eigenmode with a frequency of

In this context it is important to support a quick startup of applications deployed in the for of docker containers. This thesis explores the reasons for slow deployment and identifies three improvement opportunities: (1) improving the Docker cache hit rate; (2) speed-up the image installation operation; and (3) accelerate the application boot phase after the creation of a container.
Seismic array processing with Northern Finland Seismological Network

Sodankylä Geophysical Observatory (SGO) operates and maintains a 9-station Northern Finland Seismological Network (FN) located in northern Finland. Four of the stations are providing the data to the European Integrated Data Archive (EIDA) while five stations are working in the test regime. Every station is equipped with a 3-component broadband seismometer. Seismic array processing methods are applied using the 9-station network, which as an array is irregular and relatively large with an aperture of 455 km. As a result, the array is suitable for detecting seismic signals with large wavelengths. In this thesis, earthquake localization tests utilizing beampacking and beamforming are carried out by detecting vertical components of long-period surface wave phases. Properties of the network as an array are discussed and a method to improve the network solely for array purposes is presented. The method searches for new locations for seismic stations to reduce sidelobes in the array transfer function. keywords: seismic array, beamforming, beampacking, earthquake localization, longperiod, surface waves.
Numerical study of the homogeneous and inhomogeneous magnetic field effects on the plasma‐based radar cross‐section reduction

A numerical method based on the recursive convolution finite difference time domain was used to calculate the radar cross-section (RCS) of a square target under different conditions. The results indicate that for electron number density below 10 16 m − 3 , unmagnetised plasma provides better RCS reduction compared to magnetised plasma. For this range of electron density, the wave bending plays an important role and its effect is stronger than the resonant and non-resonant absorption. For densities higher than 2 × 10 16 m − 3 , and for collision frequencies less than plasma frequency, magnetised plasma causes greater RCS reduction compared to unmagnetised plasma due to strong resonant absorption. In this situation, the inhomogeneous magnetic field is preferred because of its broader bandwidth. The enhanced bandwidth is due to multi-resonance absorption of the inhomogeneous magnetic field. For collision frequencies above the plasma frequency, resonance absorption weakens and non-resonance absorption prevails. Then in this range of plasma parameters, the unmagnetised plasma is the proper choice for optimum RCS reduction.
Novel Composite Nanocarriers

Need for materials with high biocompatible properties have led to the development of prodrug-decorated nanoparticles. The structure of present nanostructures consists of the hydrophobic core and hydrophilic shell. The shell acts as an external envelop which enhances the colloidal stability of dispersion which protects the prodrug of the nanoparticles from photo- and thermal-initiated degradation. The composite nanoparticles coated by organic shells with functional groups were considered to govern the covalent immobilization of therapeutics/biomolecules. The nanoparticles with unique physiochemical properties may be useful as biosensors in living whole cells. The enhanced cellular drug delivery to cancer cell lines via nanoconjugates revealed that smart nanoparticles are an effective tool for transporting and delivering drugs.

Abnormal Pathways in Endometriosis in Relation to Progesterone Resistance: A Review

Introduction Endometriosis is an estrogen-dependent disorder, and recent studies suggest that progesterone resistance may contribute to the development and pathophysiology of the disorder. Based on this, identification of genetic and molecular perturbations in the endometrium of women with endometriosis is an important step towards understanding the pathogenesis of the disease, and the development of novel treatment and diagnostic strategies. Methods A systematic literature search in PubMed and Embase was performed, and 118 articles were identified for further screening. Two reviewers performed article screening independently using Covidence, and 16 studies fulfilled the inclusion criteria. The Newcastle-Ottawa Scale was used to assess the quality of these studies. Results This review presents data from eutopic endometrial biopsies from women with and without endometriosis. Several biomarkers related to a downregulated progesterone response were identified and discussed in detail. Conclusions Our review demonstrates significant results concerning the biomarkers investigated, which may substantiate the theory of progesterone resistance in women with endometriosis. However, further research is necessary to determine their specific role and relevance.
Penalized Splines Fitting for a Poisson Response Including Outliers

There have been various studies in the literature on investigating the relationship between a count response and several covariates. Most researchers study count variables and use traditional methods (i.e. generalized linear models- GLM). However, GLM is limited when dealing with outliers and nonlinear relationships. Generalized Additive Models (GAM) is an extension of GLM, where the assumptions on the link functions and components are additive and smooth, respectively. Our aim is to propose a flexible extension of GLM and demonstrate the usefulness and performance of GAMs for the analysis of Poisson data set including outliers in the response variable through extensive Monte Carlo Simulations and using three applications.
Heterogeneous differential privacy for vertically partitioned databases

Existing privacy‐preserving approaches are generally designed to provide privacy guarantee for individual data in a database, which reduces the utility of the database for data analysis. In this paper, we propose a novel differential privacy mechanism to preserve the heterogeneous privacy of a vertically partitioned database based on attributes. We first present the concept of privacy label, which characterizes the privacy information of the database and is instantiated by the classification. Then, we use an information‐based method to systematically explore the dependencies between all attributes and the privacy label. We finally assign privacy weights to every attribute and design a heterogeneous mechanism according to the basic Laplace mechanism. Evaluations using real datasets demonstrate that the proposed mechanism achieves a balanced privacy and utility.
RootsGLOH2: embedding RootSIFT 'square rooting' in sGLOH2

This study introduces an extension of the sGLOH2 local image descriptor inspired by RootSIFT ‘square rooting’ as a way to indirectly alter the matching distance used to compare the descriptor vectors. The extended descriptor, named RootsGLOH2, achieved the best results in terms of matching accuracy and robustness among the latest state-of-the-art non-deep descriptors in recent evaluation contests dealing with both planar and non-planar scenes. RootsGLOH2 also achieves a matching accuracy very close to that obtained by the best deep descriptors to date. Beside confirming that ‘square rooting’ has beneficial effects on sGLOH2 as it happens on SIFT, experimental evidence shows that classical norm-based distances, such as the Euclidean and Manhattan distances, only provide suboptimal solutions to the problem of local image descriptor matching. This suggests matching distance design as a topic to investigate further in the near future.

Progesterone receptors in complex and/or atypical endometrial hyperplasia and endometrial adenocarcinoma

Endometrial carcinoma is second most common malignancy of female genital tract with an incidence of 5.9 per 100,000 women in the developing counties. In India the incidence id 4.3 per 100,000 women. Endometrial adenocarcinoma are categorised into type I and type II histological types. Type I endometrial adenocarcinomas comprise of 80% of the cases which results due to unopposed estrogen stimulation. It is associated with lesions like Endometrial Intraepithelial Neoplasia (EIN)/Atypical Hyperplasia. Type I endometrial tumors present with a low tumor grade. Endometrial tumors of type II are also called as non endometrioid tumors. It includes serous, clear cell, mucinous and mixed tumors. These tumors account for approximately 10% of cases. Early stage and well differentiated tumors are primarily progesterone positive. Whereas poorly differentiated tumors and type II endometrial cancers are progesterone positive.
Improvement and unification of input images for photogrammetric reconstruction

In this paper, we compare techniques for 3D reconstruction from images. We focus on the pre-processing step of reconstruction: improving the input images. Several image processing algorithms are selected and tested.The main goal is to improve the quality of the resulting 3D reconstruction. We use two approaches to analyze the 3D model fitting: comparing them to the orthophotomap and measuring the position among 3D reconstructions.

Key-Value Storage for handling data in mobile devices

In the current era of technology, computers have shrinked to the point that more than half of the world population always carries one with them their mobile devices. These are used in all sorts of different activities, constantly generating information that needs to be stored or processed somewhere. To cope with the huge amounts of data generated by all of these devices, applications have resorted to Cloud services to provide them with the much needed computational and storage resources, but as these remote infrastructures still represented a bottleneck communication wise, a new paradigm has been emerging, Edge Computing. Instead of processing and storing all the data in more distant cloud services, the data is spread among mobile devices and edge servers connected in a shared network. In order to fully take advantage of the low latency times experienced in the Edge, applications still needed a distributed storage edge-oriented system, capable of handling the contents generated by all of these mobile devices. The current state-of-the-art storage systems are able to provide these applications with a storing platform that uses mobile devices or edge servers as data storing points, but neither uses both. In this thesis we propose a Key-Value Edge Storage System named Basil, that uses both mobile devices and edge infrastructures as nodes of the system, capable of providing users from different locations with a cohesive and consistent distributed storage system. Furthermore, we will test our KV store against existing NoSQL storage models deployed in the edge, as well as its own performance while varying the number of nodes it relies on.
Information transparency: Examining physicians’ perspectives toward online consumer reviews in the United States

ABSTRACT A number of U.S. healthcare organizations are taking steps to implement online review programs for physicians. However, physicians may harbor concerns about being evaluated by their patients. This research investigates both the attitudes and concerns of physicians regarding a star rating system that was implemented in an actual healthcare system in the United States. A survey regarding the implementation of a rating system was sent to physicians at a major nonprofit healthcare system. Findings demonstrate that physicians express risk perceptions about patient rating systems, which in turn influence their attitude toward the rating system, rendering them reticent about adopting such a system. Results also suggest that level of involvement, trust of the rating system, and organizational support are negatively related to physicians’ risk perceptions toward the online rating system, whereas organizational support and physician engagement are positively related to transparency. Thus, this research submits that increasing physician level of involvement in transparency initiatives, inculcating trust in online review systems, and consistently offering organizational support might help to foster physician adoption of online review systems.
Agronomic performance of the ‘Pera’ orange grafted onto nine rootstocks under the conditions of Rio Branco, Acre, Brazil

: Brazil is the world’s largest sweet orange producer, but production in the state of Acre is small and does not meet the local demand, despite having climatic conditions that are adequate for its cultivation. The objective of this study was to evaluate the behavior of the ‘Pera’ orange using different rootstocks under the edaphoclimatic conditions of Rio Branco, Acre, Brazil. We grafted the scion of the ‘Pera’ orange onto nine citrus rootstocks: ‘Cleopatra’ mandarin, TSKFL x CTTR – 013, LVK x LCR – 038, TSKC x CTQT 1439 – 004, LVK x LVA – 009, ‘Indio’citrandarin, ‘Santa Cruz Rangpur’ lime, TSKFL x CTC - 25 – 002, and TSKC x CTSW – 038. The experiment was organized in a random block design with three replicates and two plants per parcel. The following characteristics were evaluated: compatibility between scion and rootstocks, tolerance to drought, production and fruit quality. There was an effect of the rootstocks on the behavior of the ‘Pera’ variety. The ‘Santa Cruz Rangpur’ lime, ‘Indio’ citrandarin, and the hybrid LVK x LCR - 038 rootstocks presented the best performance of the ‘Pera’ orange. Therefore, they constitute an alternative to the ‘Rangpur’ lime and may be incorporated into the current ‘Pera’ orange production system of the region. – 004, – TSKFL CTC
