External cephalic version does not increase the risk of intra-uterine death: a 17-year experience and literature review

Objective: To assess the risk of intra-uterine death (IUD) after external cephalic version (ECV). Methods: In this retrospective cohort study, 1078 consecutive ECVs performed between January 1994 and March 2011 in an University teaching hospital were extracted from the computerized database to examine the risk of IUD after ECV. Results: A total of 1078 consecutive ECVs were performed over the study period. The overall successful rate was 72.8%, the successful rate was 63.1% in nulliparous and 82.7% in multiparous, respectively (p < 0.001). There was no IUD identified within 24 h after the procedure and there was only one case of IUD (0.09%) that occurred 4 weeks after an uncomplicated ECV. Conclusions: ECV is a safe procedure that does not increase the risk of IUD within and after 24 h of enrolment irrespective of outcome of ECV. Our findings have important clinical implication in terms of patient counseling regarding the decision on term breech management.
Laparoscopic-assisted one-stage resection of rectal cancer with synchronous liver metastasis utilizing a pfannenstiel incision

Laparoscopic approaches have been increasingly used in selected patients with either colorectal or liver cancer. However, simultaneous resection of colorectal carcinoma with synchronous liver metastases is still a subject of debate. The present case describes combined laparoscopic rectal and liver resections for a patient with primary rectal cancer and a synchronous liver metastasis utilizing a Pfannenstiel incision for specimen extraction. The operative time was 370 min and estimated blood loss was 400 mL. Postoperatively, the patient required parenteral analgesia for 48 h, resumed normal diet on day 3 and was discharged on day 7 after the operation. A laparoscopic approach utilizing a Pfannenstiel extraction incision may present an advantageous and attractive option for simultaneous laparoscopic rectal and liver resection in selected patients with the aim of improving short-term outcomes.
On Exploiting Problem Structure in a Basis Identification Procedure for Linear Programming

During the last decade, interior-point methods have become an efficient alternative to the simplex algorithm for solution of large-scale linear programming (LP) problems. However, in many practical applications of LP, interior-point methods have the drawback that they do not generate an optimal basic and nonbasic partition of the variables. This partition is required in the traditional sensitivity analysis and is highly useful when a sequence of related LP problems are solved. Therefore, in this article we discuss how an optimal basic solution can be generated from the interior-point solution. The emphasis of the article is on how problem structure can be exploited to reduce the computational cost associated with the basis identification. Computational results are presented that indicate that it is highly advantageous to exploit problem structure.
k-color multi-robot motion planning

We present a simple and natural extension of the multi-robot motion planning problem where the robots are partitioned into groups (colors), such that in each group the robots are interchangeable. Every robot is no longer required to move to a specific target, but rather to some target placement that is assigned to its group. We call this problem k-color multi-robot motion planning and provide a sampling-based algorithm specifically designed for solving it. At the heart of the algorithm is a novel technique where the k-color problem is reduced to several discrete multi-robot motion planning problems. These reductions amplify basic samples into massive collections of free placements and paths for the robots. We demonstrate the performance of the algorithm by an implementation for the case of disc robots and polygonal robots translating in the plane. We show that the algorithm successfully and efficiently copes with a variety of challenging scenarios, involving many robots, while a simplified version of this algorithm, that can be viewed as an extension of a prevalent sampling-based algorithm for the k-color case, fails even on simple scenarios. Interestingly, our algorithm outperforms a well established implementation of PRM for the standard multi-robot problem, in which each robot has a distinct color.
A Force Study in Brush Scrubbing

This study focuses on the analysis of the forces and moments acting on a particle to reveal the particle-removal mechanisms during a scrubbing process. The brush-asperities/substrate contact geometry during scrubbing is first investigated. The forces and moments under different lubrication modes are then determined by means of a mixed theoretical-experimental method. Finally, the analysis of the forces and moments is used to explain the experimental results and to find out the particle-removal mechanisms.
Multi-image super-resolution for fisheye video sequences using subpixel motion estimation based on calibrated re-projection

Super-resolution techniques are a means for reconstructing a higher spatial resolution from low resolution content, which is especially important for automotive or surveillance systems. Furthermore, being able to capture a large area with a single camera can be realized by using ultra-wide angle lenses, as employed in so-called fisheye cameras. However, the underlying non-perspective projection function of fisheye cameras introduces significant radial distortion, which is not considered by conventional super-resolution techniques. In this paper, we therefore propose the integration of a fisheye-adapted motion estimation approach that is based on a calibrated re-projection into a multi-image super-resolution framework. The proposed method is capable of taking the fisheye characteristics into account, thus improving the reconstruction quality. Simulation results show an average gain in luminance PSNR of up to 0.3 dB for upscaling factors of 2 and 4. Visual examples substantiate the objective results.
Resource allocation for the Choice based Education System using Semantic Web

The objective of Resource allocation for the Choice based Education System using Semantic Web is to propose an implementation model for an agent software which acts as a bridge between different educational services, content-oriented intelligence and their semantic interoperation. This paper analyzes and identifies techniques necessary to develop an automatic choice based educational system for next generation to overcome human intervention. The different educational services such as course registration, examination module, schedules the courses, assessment of student and assessment of faculty need to be automated. It means that our system adopts a learning mechanism and provides the content - oriented intelligence and more semantic interoperation between these services and content. The paper proposes semantic web is realistic technology that supports to achieve such kind of flexibility.
Use of Memory Reconsolidation in Psychotherapy and Suggestions for a Brain Imaging Study

The recent discovery by brain scientists of the reconsolidation of memory circuits (see research bibliography below) overturned the almost century-old tenet that emotional learnings and acquired responses maintained in long-term implicit memory are indelible—unerasable and permanent for the lifetime of the individual. Reconsolidation, induced endogenously through behavioral procedures, has been shown by neuroscientists to actually eliminate a target implicit memory trace, rendering it impossible to reactivate, in sharp contrast with extinction, which merely suppresses conditioned responses without erasing them, allowing relatively easy reactivation.
Selective STAT3-α or -β expression reveals spliceform-specific phosphorylation kinetics, nuclear retention and distinct gene expression outcomes

Phosphorylation of STAT3 (signal transducer and activator of transcription 3) is critical for its nuclear import and transcriptional activity. Although a shorter STAT3β spliceform was initially described as a negative regulator of STAT3α, gene knockout studies have revealed that both forms play critical roles. We have expressed STAT3α and STAT3β at comparable levels to facilitate a direct comparison of their functional effects, and have shown their different cytokine-stimulated kinetics of phosphorylation and nuclear translocation. Notably, the sustained nuclear translocation and phosphorylation of STAT3β following cytokine exposure contrasted with a transient nuclear translocation and phosphorylation of STAT3α. Importantly, co-expression of the spliceforms revealed that STAT3β enhanced and prolonged the phosphorylation and nuclear retention of STAT3α, but a STAT3β R609L mutant, with a disrupted SH2 (Src homology 2) domain, was not tyrosine phosphorylated following cytokine stimulation and could not cross-regulate STAT3α. The physiological importance of prolonged phosphorylation and nuclear retention was indicated by transcriptome profiling of STAT3−/− cells expressing either STAT3α or STAT3β, revealing the complexity of genes that are up- and down-regulated by the STAT3 spliceforms, including a distinct set of STAT3β-specific genes regulated under basal conditions and after cytokine stimulation. These results highlight STAT3β as a significant transcriptional regulator in its own right, with additional actions to cross-regulate STAT3α phosphorylation and nuclear retention after cytokine stimulation.
Designing of Testing Framework through Finite State Automata for Object-Oriented Systems using UML

Many researches to testing object-oriented systems (OOSs) have been proposed for the past decade. After all, almost all large OO software specifications still contain incompleteness, inconsistency, and ambiguity. The framework can be defined using any state-based specification notation and used to derive test cases from state-based specifications in this paper, it is demonstrated using the RSML notation. A state transition diagram (STD) derived from RSML specification provides a complete behavior of a given OOS. System testing is concerned with testing an entire system based on its specifications. In the context of object-oriented, UML development, this means that system test requirements are derived from UML analysis artifacts such as use cases, their corresponding sequence and collaboration diagrams, class diagrams. The goal is here to support the derivation of functional system test requirements, which will be transformed into test cases once we have detailed design information. In this paper, we describe a methodology in a practical way and illustrate it with an example. In this paper a framework that formally defines test data sets and their relation to the operations in a specification and to other test data sets, providing structure to the testing process.
Evaluation of the applicability of E ‐ S ‐ QUAL for assessing the service quality of social media : A case study of an academic library ’ s Facebook service

The purpose of this study is to explore the applicability of the E‐S‐QUAL instrument in the context of libraries’ social media services. As libraries have increased their use of social media such as Facebook and Twitter to interact with users and share information, the evaluation of the services has been emphasized to improve service strategies and meet user needs. However, there are no criteria or tools to measure the service quality of libraries’ social media. To address this gap, this study adopted E‐S‐QUAL and examined its applicability in this study setting. A case study was conducted using a structured questionnaire, utilizing the modified E‐S‐QUAL instrument, on an academic library’s Facebook service. The results showed that the four factor structure of the modified E‐S‐QUAL was confirmed. Items and factors had high internal consistency and convergent and discriminant validity. This study contributes to provide a tool to measure the service quality of libraries’ social media services.
Breast cancer incidence trends in Norway—explained by hormone therapy or mammographic screening?

A decline in breast cancer incidence has been observed in several countries after 2002. Reduced use of menopausal hormonal therapy (HT), as a consequence of the publication of results from the Women's Health Initiative, has been argued to be the main reason. In Norway, the governmentally funded Norwegian Breast Cancer Screening Program (NBCSP) was implemented during the same time period as the increased use of HT. This study investigated trends in breast cancer incidence by use of HT and introduction of the screening program. We obtained rates of breast cancer from the Cancer Registry of Norway and sales data of HT preparations from the Norwegian Institute of Public Health. Mammography rates were estimated from published reports. Breast cancer incidence rates increased steadily from 1956 to the end of the 20th century, particularly in women aged 55–69 during 1996–2002 residing in the counties where the NBCSP was first introduced. The rates declined after 2002–2003. HT use increased in 1987–2001, peaking around year 2000. In particular, sales of combined estrogen and progestogen preparations declined after 2002. Among women aged 55–59, rates of hormone receptor positive breast cancers peaked in 2000–2003. No such trend was seen in other age groups. In conclusion, the interpretation of breast cancer incidence trends in Norway from 1987 to 2009 is complicated because the NBCSP was introduced during a period with increasing HT use. Both factors likely contributed to the observed trends, and the role of each may vary across age groups.
Use Text Mining Approach to Generate the Draft of Indictment for Prosecutor

Motivation: The quantity of criminal cases year 2009 in Taiwan is up to 1.8 millions, Each prosecutor must handle over 211 cases per month, complaints on over loading is laud and clear. While 70 % of criminal cases are drug Abuse, public danger, larceny and fraud, these types of criminal cases may have different story though, the complexity are relative simple than cases of killing, corruption etc., but prosecutors still spend costly time on these cases handling. In this paper we try to use text mining technology to provide solution on this issue. Approach: We use the police’s investigation document of criminal case to compare with judgment history of court, and use Cosine Similarity algorithm to calculate coefficient of similarity, base on the highest coefficient, we find the closest judgment of this type of criminal case, that can be used to decide and generate the draft of indictment for prosecutor.
Energetically optimal stride frequency in running: the effects of incline and decline

SUMMARY At a given running speed, humans strongly prefer to use a stride frequency near their ‘optimal’ stride frequency that minimizes metabolic cost. Although there is no definitive explanation for why an optimal stride frequency exists, elastic energy usage has been implicated. Because the possibility for elastic energy storage and return may be impaired on slopes, we investigated whether and how the optimal stride frequency changes during uphill and downhill running. Presuming a smaller role of elastic energy, we hypothesized that altering stride frequency would change metabolic cost less during uphill and downhill running than during level running. To test this hypothesis, we collected force and metabolic data as nine male subjects ran at 2.8 m s–1 on the level, 3 deg uphill and 3 deg downhill. Stride frequency was systematically varied above and below preferred stride frequency (PSF ±8% and ±15%). Ground reaction force data were used to calculate potential, kinetic and total mechanical energy, and to calculate the theoretical maximum possible and estimated actual elastic energy storage and return. Contrary to our hypothesis, we found that neither the overall relationship between metabolic cost and stride frequency nor the energetically optimal stride frequency changed substantially with slope. However, estimated actual elastic energy storage as a percentage of total positive power increased with increasing stride frequency on all slopes, indicating that muscle power decreases with increasing stride frequency. Combined with the increased cost of force production and internal work with increasing stride frequency, this leads to an intermediate optimal stride frequency and overall U-shaped curve.

Differentiation ability and oncogenic potential of HPV‐33‐and HPV‐33+ras‐transfected keratinocytes

Five HPV‐33‐immortalized and 5 HPV‐33+ras‐transfected cell lines were characterized in terms of growth in soft agar, tumorigenic potential in nude mice, p2l expression, morphology and expression of differentiation markers in organotypic cultures. No striking differences were observed between the HPV‐33‐immortalized cell lines and their corresponding ras‐transfected counterparts as regards their tumorigenicity in nude mice (only one cell line was able to develop tumors in nude mice) or their behavior on lifted collagen gels. However, all the ros‐transfected cell lines gave rise to colonies in soft agar while only 2 HPV‐33‐transfected lines (CK1 and CK4) displayed this property. The 10 cell lines could be divided into 2 groups with respect to their phenotype in monolayer and in organotypic cultures. Lines from group 1 (CK1,3, 5 and their ras‐transfected homologous lines) shared a typical epithelial phenotype in monolayer and the ability (a) to form an epithelium similar to a CIN‐III lesion and (b) to strongly express keratins KI‐KIO and involucrin in organotypic cultures. On the other hand, for the lines from group II (CKI, CK4, CKI EJ7 and CK4EJ5), there was a correlation between an elongated phenotype in monolayer and the property (a) to form a structure similar to a microinvasive carcinoma and (b) to express vimentin and keratins K‐KI8. These cell lines, exhibiting various transformation‐associated alterations, can be considered as an in vitro model representing various stages of HPV‐33‐associated cervical carcinogenesis.
Lift generation of hummingbird wing models with flexible loosened membranes

Hummingbirds are promising reference for small flying robots in terms of their excellent ability to hover. Wing kinematics and shape of a hovering hummingbird were measured with four high-speed video cameras. Four types of wing models consisting of carbon fiber rods and polymer membranes with the same planform as the hummingbird wing were fabricated. 1-degree-of-freedom (DOF) flapping experiments with the wing models were performed, where the wing deformation and vertical force (hereafter called `lift') were measured. The model wings demonstrated similar feathering deformation as that of the hummingbird in the upstroke. In addition, the model wing with a loosened membrane which caused larger feathering deformation produced lift enough to support the weight of the hummingbird. The results suggest that hovering hummingbirds could be modeled as a pair of 1-DOF flapping wings with a thin membrane which passively feathers.
Bubble jet printhead with integrated polyimide nozzle plate

This paper reports for the first time on a new 1/3 inch thermal bubble jet printhead with integrated nozzle plate. The printhead is a combination of a standard printhead substrate with a new three-dimensional structured polyimide nozzle plate avoiding a three layer assembly known from other commercial printheads. The 50 /spl mu/m thick nozzle plate contains the fluidic channels and 208 nozzles with minimum lateral dimensions of 10 /spl mu/m. The misalignment of the two laser structured layers has proved to be less than 1 /spl mu/m. The nozzle plate is assembled with the substrate using a 3 /spl mu/m adhesive layer with an alignment accuracy of 3 /spl mu/m. The integrated nozzle plate leads to a better control of the printhead geometry and saves one processing step in production. Fully three dimensional computational fluid dynamics (CFD) simulations have been performed to investigate the effect of misalignments, the thickness of the adhesive layer and heater geometry. The agreement between simulation and experiment is better than 5%.
The use of data mining techniques to predict mortality and length of stay in an ICU

Data mining is commonly used in the healthcare industry and managing Intensive Care Unit (ICU) is no exception. This study aims to examine how data mining techniques can be employed to predict mortality and length of stay in an ICU and to evaluate various classification techniques. Real-life healthcare datasets, like MIMIC 2, incorporate an unbalanced distribution of sample sizes, which means that it is difficult to employ them to assess classification. This paper presents an analysis of a mortality prediction algorithm to evaluate the extent to which this algorithm can predict mortality rate. The model aims to facilitate the process by which medical practitioners provide customized and optimized care in the ICU.
