Design of X-band H-plane waveguide Y-junction circulator

This paper presents an approach to the design of three-port H-plane waveguide Y-junction circulator with two partial height ferrite posts in the junction region which has the advantages of high isolation and low insertion loss. With 9.375GHz center frequency and 400MHz bandwidth, the X-band waveguide circulator designed with the approach could be used in microwave measurement systems, whose VSWR is less than 1.2, insertion loss is less than 1dB and isolation is more than 20dB, which could be used in medium power systems and high power systems.
The chemical composition of wool. XI. Separation and analysis of exocuticle and endocuticle.

Whole cuticle is separated from wool by treatment in formic acid. Digestion of cuticle with pronase is complete after 36% by weight of cuticle is dissolved and the residue is shown by electron microscopy to be exocuticle, with no evidence of adhering endocuticle. The digested protein corresponds to endocuticle and the residue to exocuticle. The endocuticle contains only 3 residues per 100 of ! cystine and is generally similar in amino acid analysis to the non-keratinous material from the cortex (Peters and Bradbury 1972).
Molecular Diversity, Cultivation, and Improved Detection by Fluorescent In Situ Hybridization of a Dominant Group of Human Gut Bacteria Related to Roseburia spp. or Eubacterium rectale

ABSTRACT Phylogenetic analysis was used to compare 16S rRNA sequences from 19 cultured human gut strains of Roseburia and Eubacterium rectale with 356 related sequences derived from clone libraries. The cultured strains were found to represent five of the six phylotypes identified. A new oligonucleotide probe, Rrec584, and the previous group probe Rint623, when used in conjunction with a new helper oligonucleotide, each recognized an average of 7% of bacteria detected by the eubacterial probe Eub338 in feces from 10 healthy volunteers. Most of the diversity within this important group of butyrate-producing gut bacteria can apparently be retrieved through cultivation.
High-speed InGaP/GaAs transistors with a sidewall base contact structure

We have fabricated InGaP/GaAs double heterojunction bipolar transistors with a sidewall base contact structure. These transistors operate in both emitter-up and emitter-down modes. Symmetric characteristics of the cutoff frequency f/sub T/=68 GHz and the maximum oscillation frequency f/sub max/=31 GHz were obtained at a base-collector bias V/sub BC/ of 0 V. For emitter-down operation, f/sub T/ was found to reach a maximum of 78 GHz when the base-collector junction was forward biased at 0.9 V. The product of f/sub T/ for emitter-down operation and f/sub T/ for emitter-up operation was 5.3/spl times/10/sup 3/ GHz/sup 2/, which is about six times that of previously reported SiGe heterojunction bipolar transistors.
At-home monitoring after surgery/anaesthesia - a challenge.

RATIONALE, AIMS AND OBJECTIVES Day surgery is evolving, with a majority of recoveries occurring at home. There is, in parallel, an evolution in telemedical technology. The aim of the present project was to identify patients' willingness to use predefined follow-up techniques and to clinically test preferred techniques at home using a two-step study. ┅ METHODS: In Part I, a paper-based questionnaire study of identified patients' attitudes with three follow-up techniques was used. In Part II, a feasibility test of a mobile (smart-phone) application for follow-up at home was used. RESULTS Part I showed overall positive attitudes to telemedical follow-ups. Part II showed the preference for a follow-up technique with a mobile application was not fully consistent with the clinical study of the smart-phone app, where there was a large non-response. The application provided safe transfer of data to the hospital and helped make it easy to retrieve and analyse patient self-assessment of recovery. This application is one-way directed, and no feedback to the patient was given, which may have influenced the non-response. CONCLUSION Bringing telemedicine into follow-up after surgery/anaesthesia is requested, and furthermore, the feasibility study on day surgery presented here shows that it is technically easy to perform and will provide robust information. It should be noted that further studies are needed in order to find better patient cooperation.
The Intubating Laryngeal Mask Airway: Effect of Handle Elevation on Efficacy of Seal, Fibreoptic Position, Blind Intubation and Airway Protection

We conducted three studies to test the hypothesis that elevation of the intubating laryngeal mask (ILM) handle increases efficacy of seal, changes fibreoptic position, prevents aspiration of regurgitated fluid and improves intubation. In study 1, the ILM was inserted into 20 paralysed, anaesthetized patients and 20 cadavers. Oropharyngeal leak pressure and fibreoptic position were measured at an intracuff pressure of 0, 60 and 120 cm H 2 O with 0, 20 and 40 N of elevation force. In study 2, the oesophageal pressure at which regurgitation and aspiration occurred was measured in 20 cadavers with the ILM at the above intracuff pressures and elevation forces and 10 cadavers without the ILM (controls). In study 3, ease of blind intubation (first attempt only) was determined in 20 paralysed, anaesthetized patients at 0 and 40 N elevation force. In study 1, there was a significant increase in oropharyngeal leak pressure with increasing elevation force at an intracuff pressure of 0 and 60 cm H 2 O. There were no changes in fibreoptic position. Oropharyngeal leak pressure and fibreoptic position were similar between patients and cadavers. In study 2, oesophageal pressure for regurgitation and aspiration was usually greater for the ILM than controls (all: P<0.05. Aspiration and regurgitation usually occurred at the same oesophageal pressure. In study 3, blind intubation was more successful at 0 N than 40 N (15/20 v 8/20, P=0.03). We conclude that elevation of the ILM handle has little clinical utility other than as a temporary measure to improve the efficacy of the seal.
CLINICAL EVALUATION OF EMERGENCY ENDOSCOPIC HEMOSTASIS WITH BIPOLAR FORCEPS IN NON‐VARICEAL UPPER GASTROINTESTINAL BLEEDING

The present study was designed to evaluate the usefulness and safety of bipolar hemostatic forceps, known as a less invasive and highly safe means of thermal coagulation used for hemostasis in cases of non‐variceal upper gastrointestinal bleeding. This technique of bipolar forceps is simple, safe and unlikely to induce complications, and is therefore promising as a new technique of endoscopic hemostasis. The study involved 39 cases where hemostasis was attempted with bipolar forceps to deal with non‐variceal upper gastrointestinal bleeding, including 28 cases of gastric ulcer, six cases of duodenal ulcer, three cases of bleeding after endoscopic submucosal dissection (ESD), one case of Mallory‐Weiss syndrome and one case of postoperative bleeding from the anastomosed area. There were 34 males and five females, with a mean age of 63.6 years. Bipolar forceps were the first‐line means of hemostasis in cases of oozing bleeding (venous bleeding), pulsatile or spurting bleeding (arterial bleeding) and exposed vessels without active bleeding. The primary hemostasis success rate was 92.3%, and the re‐bleeding rate was 0%. In cases where the bleeding site was located along the tangential line or in cases where large respiration‐caused motions hampered identification of the bleeding site, hemostasis by means of coagulation was easily effected by application of electricity while the forceps were kept open and compressed the bleeding area. In addition, there were no complications. This technique of bipolar forceps is simple, safe and unlikely to induce complications, and is therefore promising as a new technique of endoscopic hemostasis.
Phase I dose-finding study of weekly single-agent patupilone in patients with advanced solid tumors.

PURPOSE To evaluate the safety and maximum-tolerated dose (MTD) of weekly patupilone, a natural epothilone B, in patients with advanced solid tumors. PATIENTS AND METHODS Patients were treated with patupilone (0.3 to 3.6 mg/m2) for 6 weeks on/3 weeks off or 3 weeks on/1 week off. Dose-limiting toxicities (DLTs), MTD, and pharmacokinetics were determined for each schedule of administration. RESULTS Ninety-one patients were enrolled. The most common tumor types included ovarian, breast, and colon cancers. Doses of patupilone less than 2.5 mg/m2 using either the 6 weeks on/3 weeks off or the 3 weeks on/1 week off schedule were tolerated well. At higher doses, DLTs were observed using both dosing schedules, with diarrhea the most common DLT. The MTD for both treatment schedules was 2.5 mg/m2. After a short infusion, patupilone blood concentrations declined in a multiphasic manner with a terminal half-life of 4 days. Drug clearance was nonrenal and was not related to body-surface area. Over the dose range evaluated, systemic drug exposure was approximately dose proportional. Three patients achieved a partial response, and 31 patients had stable disease. Two patients experiencing a partial response had received prior taxane therapy. CONCLUSION Patupilone is well tolerated when administered at a dose of 2.5 mg/m2, using either a 6 weeks on/3 weeks off or a 3 weeks on/1 week off schedule. In contrast with murine studies, patupilone has a relatively prolonged terminal half-life in humans. The partial responses in patients previously treated with taxanes is consistent with promising preclinical results.
Web site classification based on key resources

Automatic web site classification has a wide application prospect. However, there is a little research on the web site classification. Many methods represent the web site as normal text and still use the methods of text classification. But web sites are combination of many web pages via hyperlinks, so the methods of text classification are not suitable for web sites. This paper proposes a new approach to web site classification. First of all, we get the key resources of web site through a reasonable pruning strategy. Then abstract the topic vector of web site from the key resources, according to the web site's structure information and content information. To reflect the structure information of the web site, we use an improved vector space model which includes both structure feature words and content feature words to represent the topic vector of the web site.
Acclimatization to dry heat: active men vs. active women.

Physiological responses to exercise in dry heat were compared between six active men [maximum O2 consumption (VO2max), 51.4 +/- 1.2 ml . kg-1 . min-1] and four active women (VO2max, 47.2 +/- 1.3 ml . kg-1 . min-1) before, during, and after heat acclimatization. Subjects cycled a maximum of 2 h at 40% VO2max at 45 degrees C dry-bulb temperature, 23 degrees C wet-bulb temperature for 11 days. Prior to acclimatization there were no sexual differences for performance time, rate of increase of rectal temperature (delta Tre), or sweat rate per degree C increase of rectal temperature (msw/delta Tre). Sweat rate (msw) was greater for the men than for the women. Although there was no difference in the rate of increase of heart rate (delta HR), HR for the women was maintained 15-20 beats . min-1 higher than for the men. Acclimatization occurred for both sexes as indicated by reduced Tre and HR and increased msw and performance time. With acclimatization the women had longer performance times than the men. Even though the men still had greater msw, delta Tre was also greater; therefore msw/delta Tre for the men was less than for the women. Neither HR nor delta HR was different between the sexes. Throughout, resting hematocrit for the women was less than for the men; no changes in hematocrit were observed during exercise or with acclimatization. Plasma protein concentration increased during exercise on all days; no changes in plasma osmolality were observed. It is concluded that active women perform exercise of equal relative intensity in dry heat as well as active men. Moreover active women acclimatized to heat at a faster rate or to a greater extent than did active men.
Atrial fibrillation and incidence of dementia

Background: Previous systematic reviews that examined whether atrial fibrillation (AF) is associated with dementia have relied on different study designs (including retrospective ones) and did not evaluate risk using meta-analysis. Methods: We searched Medline, Embase, and PsychINFO in September 2010 for published prospective studies reporting on the association between baseline AF and incident dementia. Pooled odds ratios for AF and dementia were calculated using the random effects model, with heterogeneity assessed using I2. Results: We identified 15 relevant studies covering 46,637 participants, mean age 71.7 years. One study that reported no significant difference in Mini-Mental State Examination scores between patients with or without AF could not be pooled. Meta-analysis of the remaining 14 studies showed that AF was associated with a significant increase in dementia overall (odds ratio [OR] 2.0, 95% confidence interval [CI] 1.4 to 2.7, p < 0.0001), with substantial heterogeneity (I2 = 75%). When stratified by participants, the association was significant (with little heterogeneity) in studies focusing solely on patients with stroke (7 studies, OR 2.4, 95% CI 1.7 to 3.5, p < 0.001, I2 = 10%), and of borderline significance (with substantial heterogeneity) for studies in broader populations (7 studies, OR 1.6, 95% CI 1.0 to 2.7, p = 0.05, I2 = 87%). For conversion of mild cognitive impairment to dementia, one study showed a significant association with AF (OR 4.6, 95% CI 1.7 to 12.5). Conclusion: There is consistent evidence supporting an association between AF and increased incidence of dementia in patients with stroke whereas there remains considerable uncertainty about any link in the broader population. The potential association between AF and incident dementia in mild cognitive impairment merits further investigation.
Confocal laser scanning microscopy study of dentinal tubules in dental caries stained with alizarin red

Dentin morphology and the lesion found in dental caries have been studied for many years. It was first observed under optical microscopy, and later using electron microscopy. Confocal laser scanning microscopy (CLSM) applied with several fluorescent dyes such as alizarin red to see normal dentinal tubules. However, as far as authors aware, the CLSM studies of dentinal tubules in human caries using alizarin red is rare. The aim of this study is to examine histopathological and morphological changes in dentinal tubules of dentin caries stained with alizarin red using CLSM. Fifteen extracted carious teeth (premolar or molar) was collected and fixed in neutral formalin solution buffered with phosphate buffer, rinsed and stored in calcium free phosphate buffer saline (PBS) at 4°C. The specimens were dehydrated and embedded in resin. Longitudinal or cross sections were cut and polished and then stained with alizarin red S (100 µg/ml) in 0.5 M HCl solution for 24-48 hour at 37°C. After dehydration specimens were mounted on glass slide and examined under CLSM using epi-flourescent mode or transmission light mode with wave length of 512 nm. The images of dentinal tubules were taken serially and optimum images of three-dimensional structures were reconstructed using software of CLSM. Histopathological changes of dentinal tubules in human caries showed area of demineralized dentin, translucent zone, and normal area. The dentinal tubules were thin and had numerous branches. In conclusion, confocal microscopy revealed Study shows that confocal microscopy revealed histopathological changes in dentinal tubules affected by carious lesions.
EVIDENCE FOR AUTOPOLYPLOIDY IN EPILOBIUM ANGUSTIFOLIUM (ONAGRACEAE)

Most students of evolution consider autopolyploidy to be rare in nature. Because the majority of natural polyploids show only bivalent formation or have a relatively low frequency of multivalents a t meiosis, such polyploids have usually been considered to be allopolyploids or at least segmental allopolyploids (see Stebbins, 1950, Chapter 8) . Autopolyploids were expected to have high rather than low frequencies of multivalent formation and, in addition, they were expected to show evidence of tetrasomic inheritance. This relatively uncomplicated view for the basis of chromosome pairing associations in polyploids, which assumed that the presence of quadrivalents was due mainly to structural homologies of the chromosomes, has prevailed to the present time. Evidence has recently been accumulating, which clearly shows that in some polyploid plants, a lower than expected quadrivalent frequency might be caused by genetic control of chromosome pairing (Stanford, 195 1 ; Lesins, 195 7 ; Gerstel, 1963; Wernsman et al., 1964; Riley, 1960, 1965; Wagenaar, 1966) . However, thus far, such control has been found only in those polyploids in which homoeologous relationships of the chromosomes have been demonstrated. In many autotetraploids roughly two thirds of the chromosomes are united as quadrivalents (Morrison and Rajhathy, 1960a, 1960b; Sved, 1966) . Natural polyploids whose quadrivalent frequency is comparable to that found by Morrison and Rajhathy may reasonably be assumed to be autoploid. However, in those polyploid species where the quadrivalent frequency is much lower,
Perceived Benefits and Psychosocial Outcomes of a Brief Existential Family Intervention for Cancer Patients/Survivors

This study assessed a range of benefits from participation in a brief existential intervention consisting of a semi-structured videotaped interview with cancer patients and their families designed to illuminate a life legacy for the family (the Life Tape Project [LTP]). Results indicated the majority reported intervention-specific benefits, especially in the areas of symbolic immortality (passing on personal values and philosophy), self-reflection and growth, and improved family cohesion and communication. Participants, particularly those who had perceived their cancer as a threat of death, serious injury, or threat to their physical integrity, and responded with intense fear or helplessness, also reported more general reductions in mood disturbance, improvements in aspects of well-being (including overall quality of life), satisfaction with the understanding they received, and enhanced cancer-related posttraumatic growth. In short, the LTP is a brief, inexpensive, existential intervention that can yield broad positive psychosocial changes for a majority of participants.
The hunvec framework for NN-CRF-based sequential tagging

In this work we present the open source hunvec framework for sequential tagging, built upon Theano and Pylearn2. The underlying statistical model, which connects linear CRF-s with neural networks, was used by Collobert and co-workers, and several other researchers. For demonstrating the flexibility of our tool, we describe a set of experiments on part-of-speech and named-entity-recognition tasks, using English and Hungarian datasets, where we modify both model and training parameters, and illustrate the usage of custom features. Model parameters we experiment with affect the vectorial word representations used by the model; we apply different word vector initializations, defined by Word2vec and GloVe embeddings and enrich the representation of words by vectors assigned trigram features. We extend training methods by using their regularized (l2 and dropout) version. When testing our framework on a Hungarian named entity corpus, we find that its performance reaches the best published results on this dataset, with no need for language-specific feature engineering. Our code is available at http://github.com/zseder/hunvec
Inferring speciation and extinction processes from extant species data

Querying the past is hard. Speciation and extinction processes are on a scale of thousands to millions of years. Thus, they are most often studied by reconstructing the evolutionary past. This past is reconstructed using phylogenetic methods either on the basis of data from living species or by directly examining the fossil record. Robust methods for inferring the evolutionary past purely on the basis of living species would allow us to understand speciation and extinction processes for the large number of groups without a good fossil record.
nextnano: General Purpose 3-D Simulations

nextnano is a semiconductor nanodevice simulation tool that has been developed for predicting and understanding a wide range of electronic and optical properties of semiconductor nanostructures. The underlying idea is to provide a robust and generic framework for modeling device applications in the field of nanosized semiconductor heterostructures. The simulator deals with realistic geometries and almost any relevant combination of materials in one, two, and three spatial dimensions. It focuses on an accurate and reliable treatment of quantum mechanical effects and provides a self-consistent solution of the Schrodinger, Poisson, and current equations. Exchange-correlation effects are taken into account in terms of the local density scheme. The electronic structure is represented within the single-band or multiband kldrp envelope function approximation, including strain. The code is not intended to be a ldquoblack boxrdquo tool. It requires a good understanding of quantum mechanics. The input language provides a number of tools that simplify setting up device geometry or running repetitive tasks. In this paper, we present a brief overview of nextnano and present four examples that demonstrate the wide range of possible applications for this software in the fields of solid-state quantum computation, nanoelectronics, and optoelectronics, namely, 1) a realization of a qubit based on coupled quantum wires in a magnetic field, 2) and 3) carrier transport in two different nano-MOSFET devices, and 4) a quantum cascade laser.
Positron emission tomography in combination with sentinel node biopsy reduces the rate of elective neck dissections in the treatment of oral and oropharyngeal cancer.

PURPOSE To assess the impact of a diagnostic ladder including [(18)F]fluorodeoxyglucose positron emission tomography (PET) and lymphoscintigraphy guided sentinel node biopsy (LS/SNB) on neck treatment in patients with oral and oropharyngeal squamous cell carcinoma (OOSCC). PATIENTS AND METHODS Prospectively, 62 patients with resectable T1-3 OOSCC underwent computed tomography (CT) and PET. Patients without neck uptake in PET were defined as cN0 and were accrued for LS/SNB. Results were correlated with histopathology. The traditional guidelines according to CT findings were compared to the actual regimen and the outcome. RESULTS Sensitivity, specificity, validity, and positive and negative predictive value of PET versus CT were 72% v 89%, 82% v 77%, 79% v 80.5%, 62% v 61.5%, and 88% v 94.5% (not significant). Thirty-eight PET negative patients underwent LS/SNB. Sentinel lymph nodes were found in all 38 patients. Five patients had positive nodes (PET false-negatives) and underwent neck dissection (ND). Fifty-one neck sides in 36 patients who were CT-negative would have been treated with selective ND according to the guidelines, and at least 45 neck sides would have had to undergo extensive ND because of positive CT findings (96 of 124 neck sides). In contrast, PET in combination with LS/SNB spared 59 neck sides, and 41 of 124 neck sides actually underwent ND as a result of PET staging, LS/SNB, and intraoperative decision. After a median follow-up of 35 months, two patients (both cN+ve and pN+ve) suffered from neck relapses. CONCLUSION Diagnostics using PET in combination with LS/SNB considerably reduced the number of extensive ND in OOSCC as compared to CT without locoregional hazard.
