Superconducting gaps in FeSe studied by soft point-contact Andreev reflection spectroscopy

FeSe single crystals have been studied by soft point-contact Andreev-reflection spectroscopy. Superconducting gap features in the differential resistance dV/dI(V) of point contacts such as a characteristic Andreev-reflection double-minimum structure have been measured versus temperature and magnetic field. Analyzing dV/dI within the extended two-gap Blonder-Tinkham-Klapwijk model allows to extract both the temperature and magnetic field dependence of the superconducting gaps. The temperature dependence of both gaps is close to the standard BCS behavior. Remarkably, the magnitude of the double-minimum structure gradually vanishes in magnetic field, while the minima position only slightly shifts with field indicating a weak decrease of the superconducting gaps. Analyzing the dV/dI(V) spectra for 25 point contacts results in the averaged gap values = 1.8+/-0.4meV and =1.0+/-0.2 meV and reduced values 2 /kTc=4.2+/-0.9 and 2 /kTc=2.3+/-0.5 for the large (L) and small (S) gap, respectively. Additionally, the small gap contribution was found to be within tens of percent decreasing with both temperature and magnetic field. No signatures in the dV/dI spectra were observed testifying a gapless superconductivity or presence of even smaller gaps.
Width of the charge-transfer peak in the SU(N) impurity Anderson model and its relevance to nonequilibrium transport

We calculate the width $2\Delta_{\text{CT}}$ and intensity of the charge-transfer peak (the one lying at the on-site energy $E_d$) in the impurity spectral density of states as a function of $E_d$ in the SU($N$) impurity Anderson model (IAM). We use the dynamical density-matrix renormalization group (DDMRG) and the noncrossing-approximation (NCA) for $N$=4, and a 1/$N$ variational approximation in the general case. In particular, while for $E_d \gg \Delta$, where $\Delta$ is the resonant level half-width, $\Delta_{\text{CT}}=\Delta$ as expected in the noninteracting case, for $-E_d \gg N \Delta$ one has $\Delta_{\text{CT}}=N\Delta$. In the $N$=2 case, some effects of the variation of $% \Delta_{\text{CT}}$ with $E_d$ were observed in the conductance through a quantum dot connected asymmetrically to conducting leads at finite bias [J. K\"onemann \textit{et al.}, Phys. Rev. B \textbf{73}, 033313 (2006)]. More dramatic effects are expected in similar experiments, that can be carried out in systems of two quantum dots, carbon nanotubes or other, realizing the SU(4) IAM.
Micro-Organisms in the Intestines of Earthworms

SUMMARY Actinomycetes and bacteria, but not fungi, increase rapidly in numbers during the passage of food through the worm gut. Enzymes produced by the worm rather than micro-organisms seem to be the main agents digesting cellulose and chitin. The rate that material moves through the intestine depends on whether the animal is feeding; food takes about 20 hr. to pass, but when burrows are being formed material passes in about 12 hr.
Electron microscopic study of Conidium ontogeny in Coniothyrium cupressacearum (Coelomycetes)

Coniothyrium cupressacearum (Morelet) Morelet, exhibiting annellated conidiogenous cells in light microscopy, was examined by transmission electron microscopy. Since the conidial wall is formed de novo, i.e. not continuous with a pre-existent layer of the conidiogenous cell wall, the conidiogenesis is clearly phialidic. After production of a number of conidia, a percurrent proliferation of the phialide collar occurs; this explains the annellated appearance. The annellide is not considered to be a special kind of conidiogenous cell but a variation of either the phialide or the aleuriophore.
Grammatical gender processing in L2: Electrophysiological evidence of the effect of L1–L2 syntactic similarity*

This study examines the effect of proficiency and similarity between the first and the second language on grammatical gender processing in L2. In three experiments, we manipulated gender agreement violations within the determiner phrase (DP), between the determiner and the noun (Experiment 1), the postposed adjective and the noun (Experiment 2) and the preposed adjective and the noun (Experiment 3). We compared the performance of German advanced learners of French to that of French native controls. The results showed a similar P600 effect for native and non-native speakers for agreement violations when agreement rules where similar in L1 and L2 (Experiment 1, depending on proficiency), whereas no effect was found for L2 learners when agreement rules varied across languages. These results suggest that syntactic processing in L2 is affected by the similarity of syntactic rules in L1 and L2.
Comparing the preferred driving postures between Chinese and French drivers

The effects of seat height and anthropometric dimensions on preferred driving posture were investigated using a multi-adjustable mock-up in the present study. More specifically, Chinese and French drivers were compared. Sixty-one subjects (40 'French-born' and 21 'Chinese-born') participated in the experiment, covering a large range of stature and sitting height to stature ratio. Preferred driving postures were collected from three seat heights fixed at 250, 300 and 350 mm. Apart from hip fore-aft position, seat height only affected trunk-thigh angle while all other inter-segment angles including trunk inclination were kept invariant. Differences were only found in trunk related angles between different participant groups. Shorter persons tended to have a less inclined trunk while they had almost the same trunk-thigh angle as taller persons. Chinese participants had a more opened trunk-thigh angle and a more inclined trunk due to the fact that their hips were positioned more forward in the seat. Results support the assumption that the inter-segmental (joint) angles of the preferred driving posture are not dependent on driver's anthropometry. Practitioner Summary: Effects of seat height and anthropometric dimensions on preferred driving posture were investigated. The findings would be useful for improving vehicle interior design for a better accommodation of target driver population with a large variation of anthropometric dimensions due to market globalization.
Water supply project feasibilities in fringe areas of Kolkata, India

Abstract. Water supply management to the peri-urban areas of the developing world is a complex task due to migration, infrastructure and paucity of fund. A cost-benefit methodology particularly suitable for the peri-urban areas has been developed for the city of Kolkata, India. The costs are estimated based on a neural network estimate. The water quality of the area is estimated from samples and a water quality index has been prepared. A questionnaire survey in the area has been conducted for relevant information like income, awareness and willingness to pay for safe drinking water. A factor analysis has been conducted for distinguishing the important factors of the survey and subsequent multiple regressions have been conducted for finding the relationships for the willingness to pay. A system dynamics model has been conducted to estimate the trend of increase of willingness to pay with the urbanizations in the peri-urban areas. A cost benefit analysis with the impact of time value of money has been executed. The risk and uncertainty of the project is investigated by Monte Carlos simulation and tornado diagrams. It has been found that the projects that are normally rejected in standard cost benefit analysis would be accepted if the impacts of urbanizations in the peri-urban areas are considered.
Determining Challenge from Stress and Workload in a Complex Task.

BRYANT, MICHELLE RENEE. Determining Challenge from Stress and Workload in a Complex Task. (Under the direction of Dr. Anne Collins McLaughlin) The experiences of workload and stress are often considered linked to the difficulty in a task and performance on that taskas difficulty increases, workload and stress tend to increase and performance tends to decline at high difficulty levels. These effects are often assumed to be stronger in individuals with less resources available for the task or personality traits that can alter the subjective experience of stress and workload. An experiment was performed to assess the effects of personality, age group, and task difficulty on performance of a complex task. Reported stress during performance and reported mental workload during performance were also collected. Analyses were performed using multi-level modeling and found effects of age and task difficulty. It is concluded that the subjective experiences of stress and workload may differ from each other at different levels of difficulty.
Entomophilous pollination in rape (Brassica napus L. var. oleifera) in Brazil

Summary — The present experiment was performed to study the development of rape flowers (Brassica napus var oleifera, cv CTC 4), volume and concentration of nectar produced, insects involved in the pollination and their behaviour in the flower (nectar or pollen collection), and the effects of this pollination on the production of pods and seeds, and germination and oil content in the seeds. The most frequent insect visitors to the flower were: Apis mellifera, 80.6%; Trigona spinipes, 12.8% and Dialictus sp, 6.6%. The sugar content averaged of 16.3 μg, and the percentage of sugar in the nectar collected from workers (Apis mellifera) was 37 ± 18%. Total protein content and ether extract in the pollen were 17.5 and 6.7%, respectively. The visits of A mellifera collecting nectar and pollen contributed to pollination and to an increased production of pods per square meter and individual seed weight. No influence was registered on total number of seeds per pod, normal seeds (fully formed) or abnormal seeds (shrivelled and undersized) per pod, percentage of seed germination and oil content.
METALS IN THE EXOSPHERE OF THE HIGHLY IRRADIATED PLANET WASP-12b

We present near-UV transmission spectroscopy of the highly irradiated transiting exoplanet WASP-12b, obtained with the Cosmic Origins Spectrograph on the Hubble Space Telescope. The spectra cover three distinct wavelength ranges: NUVA (2539–2580 Å), NUVB (2655–2696 Å), and NUVC (2770–2811 Å). Three independent methods all reveal enhanced transit depths attributable to absorption by resonance lines of metals in the exosphere of WASP-12b. Light curves of total counts in the NUVA and NUVC wavelength ranges show a detection at a 2. 5σ level. We detect extra absorption in the Mg ii λλ2800 resonance line cores at the 2. 8σ level. The NUVA, NUVB, and NUVC light curves imply effective radii of 2.69 ± 0.24 RJ, 2.18 ± 0.18 RJ, and 2.66 ± 0.22 RJ respectively, suggesting the planet is surrounded by an absorbing cloud which overfills the Roche lobe. We detect enhanced transit depths at the wavelengths of resonance lines of neutral sodium, tin, and manganese, and at singly ionized ytterbium, scandium, manganese, aluminum, vanadium, and magnesium. We also find the statistically expected number of anomalous transit depths at wavelengths not associated with any known resonance line. Our data are limited by photon noise, but taken as a whole the results are strong evidence for an extended absorbing exosphere surrounding the planet. The NUVA data exhibit an early ingress, contrary to model expectations; we speculate this could be due to the presence of a disk of previously stripped material.
QUANTITA'riVE STIUJ)IES OF NASAL CARRIERS OF STAPH1YLOC(OCC1 AMONG H-O'SPITALIZED PATIENTS *

Several investigators have shown that patients who are nasal carriers of staphylococci have a higher incidence of postoperative infections and other types of staphylococcal disease than have patients who are not nasal carriers (1, 2). In these studies, the increased incidence of infections was due predominantly to staphylococci of the same phage type as those isolated from the nose of the patient before the infections occurred. If the nasal carrier is a major source of his own hospital-acquired staphylococcal infection, qualitative and quantitative changes in the nasal flora of staphylococci should be important in understanding the origin of a portion of staphylococcal disease. Several reports have been made of qualitative studies of nasal carriers of staphylococci in hospitalized patients (3-6). Williams and colleagues (1) found that carriers of tetracyclineresistant strains had a higher incidence of infections than had carriers of tetracycline-sensitive strains. Also carriers of "virulent" strains, which were defined as staphylococci causing two or more infections in a short period, had more frequent infections than carriers of "nonvirulent" strains. Quantitative studies of nasal carriers have been reported from a mental hospital having a reservoir of largely drug-susceptible staphylococci (7, 8). Similar studies have been continued in a general hospital with a large proportion of physically ill patients and a large reservoir of antibiotic-resistant staphylococci. In this setting, the dissemination of staphylococci to a patient's environment was correlated with the quantity of staphylococci that could be recovered from his nose. In addition, carriers of 80/81 staphylococci and patients with certain diseases were found to be heavier
Arthur's multiplicity formula for certain inner forms of special orthogonal and symplectic groups

Let G be a special orthogonal group or an inner form of a symplectic group over a number field F such that there exists a non-empty set S of real places of F at which G has discrete series and outside of which G is quasi-split. We prove Arthur’s multiplicity formula for automorphic representations of G having algebraic regular infinitesimal character at all places in S.
Critical analysis of risk assessment methods applied to construction works

DOI : 10.7764/RDLC.16. 1.104 This paper studies the possibility of using the following occupational risk assessment methods for construction works: INSHT, ANACT, THREP, SHERPA, RNUR, EVENT TREE, LEST, FINE, ERGONOMIC ANALYSIS and PSYCHOSOCIAL FACTORS. Of these methods, INSHT, ANACT, RNUR and FINE have been selected with the objective of applying them to real building works, in order to determine the discrepancies in the results obtained compared to the risks analyzed. The results make it possible to ascertain the types of risk which each method most reliably detects, there being methods which are not able to detect extreme or very low risks. It is concluded that if a single risk assessment method is used, the results do not entirely reflect reality, as such it is necessary to establish a new risk assessment methodology for construction works.

Projected Cropland Requirements And Land Availability For Major U.S. Production Regions

The decade of the 70Â’s witnessed an expansion in U.S. cropped acreage in response to rising foreign demand. During this same period, substantial acreages of cropland were converted to non-agricultural uses. An issue arising from these land adjustments is whether available cropland will constrain agricultural production in the near future? This paper provides some insight by developing cropland requirements to meet 1985 demand for major U.S. commodities and then compares these projections with recent data in cropland availability. The results indicate that agricultural production should not be constrained by land availability at the national level, even in the event of high demand levels and slowed yield growth. When the analysis is extended to specific farm production regions, some shifts in production are suggested.
Computing a Trust Region Step

We propose an algorithm for the problem of minimizing a quadratic function subject to an ellipsoidal constraint and show that this algorithm is guaranteed to produce a nearly optimal solution in a finite number of iterations. We also consider the use of this algorithm in a trust region Newton's method. In particular, we prove that under reasonable assumptions the sequence generated by Newton's method has a limit point which satisfies the first and second order necessary conditions for a minimizer of the objective function. Numerical results for GQTPAR, which is a Fortran implementaton of our algorithm, show that GQTPAR is quite successful in a trust region method. In our tests a call to GQTPAR only required 1.6 iterations on the average.
Social media adoption among lecturers at a traditional university in Eastern Cape Province of South Africa

Background: There is shortage of critical skills in the South African economy. One of the reasons for this shortage is that many students at traditional universities are not completing their degree within the prescribed time frame. The massification of education at traditional universities compounds this problem as there is a decrease in the interaction between lecturers and students. Information and communication technologies, and specifically social media, have been identified as a possible solution to aid traditional universities to improve their throughput rate. Social media has become an essential tool to increase student–lecturer interaction, collaboration and communication in academic setting. Objective: The purpose of the study was to examine social media adoption among lecturers at a traditional university in Eastern Cape Province of South Africa. Method: The unified theory of acceptance and use of technology (UTAUT) framework was used as the theoretical foundation of the questionnaire that was distributed to 300 full-time staff members. A response rate of 39% was attained. Factor analysis was used to test the relationship between variables. Contribution: The study’s contribution is to the theoretical body of knowledge that affirms that the UTAUT framework is an appropriate tool to use to test adoption of social media at traditional universities. Conclusion: The findings indicated that academics are conversant with emerging technologies and could incorporate these technologies into academic settings with an aim to increase communication and interaction among lecturers and learners. The results revealed that performance expectancy, social influence, effort expectancy and behavioural intention have a positive influence on social media adoption and continued use by academics in teaching and learning at traditional university. The facilitating condition scale was not statistically significant, but must be considered by management in order to improve the adoption of social media among lecturers.
Evaluation of occupational genotoxic risk in a Brazilian hospital

Many therapeutic, diagnostic and prophylactic procedures used in hospitals are of potential genetic risk. An evaluation was mad e of genotoxic occupational risk in 42 workers from the Hospital de Clinicas de Porto Alegre, RS, Brazil, who had been occupationall y exposed to lead (solder), ethylene oxide (sterilization area), antineoplastic drugs (nurses and pharmacists) or ionizing radiat ion. They were compared with 42 unexposed individuals. There was an increase in the frequency of binucleated cytochalasin-blocked lymphoc ytes with micronuclei, though it was not significant (P = 0.058). The groups exposed to antineoplastic drugs and radiation had a sig nificant increase in micronuclei frequency (P = 0.038 and P = 0.022, respectively). The high frequencies of dicentric bridges suggest th e action of clastogenics in these two groups. These results suggest that the safety procedures adopted were very important to protect worke rs from exposure to mutagenic agents and should be improved in the radiological and chemotherapeutical areas.
The effect of buffering dairy cow diets with limestone, Acid Buf or sodium bicarbonate on production response and rumen metabolism

A high concentrate TMR, formulated to be potentially acidotic, was used to construct three dietary treatments in which Acid Buj the skeleton remain of sea weed Lithothamnium calcareum, was compared against limestone (control) and sodium bicarbonate plus limestone. The diet contained 4 glkg DM of Acid Buf or 3.5 g/kg DM limestone (control) or 3. lg/kg DM limestone plus 8 g/ kg DM of sodium bicarbonate, respectively. The response to treatment was measured using 6 ruminally cannulated lactating Holstein cows allocated to treatments according to a balanced 3 x 3 (n=2) Latin square design, with three treatments and three periods. The total experimental period was 66 days in which every cow received each diet for a period of 15 days prior to a data collection period of 7 days. During each data collection period milk was collected and analyzed for its solid and mineral contents. Feed dry matter consumption was also recorded Daily milk yield was 27.6, 29.1 and 31.6 liters /cow for the control, sodium bicarbonate and Acid Buf treatments, respectively, with milk containing 38.6, 41.8 and 42.1 g/kg fat and 34.3, 33.8 and 34. 7 glkg protein. The trial indicated that supplementing the diet of dairy cows with approximately 90 g/day of Acid Buf may have a greater impact on milk production than 180 glday of sodium bicarbonate and resulted in increase in daily milk input production of 4 liters/cow/day.
A pr 2 01 2 A Sound and complete axiomatisations of coalgebraic language equivalence

Coalgebras provide a uniform framework to study dynamical systems, including several types of automata. In this paper, we make use of the coalgebraic view on systems to investigate, in a uniform way, under which conditions calculi that are sound and complete with respect to behavioral equivalence can be extended to a coarser coalgebraic language equivalence, which arises from a generalised powerset construction that determinises coalgebras. We show that soundness and completeness are established by proving that expressions modulo axioms of a calculus form the rational fixpoint of the given type functor. Our main result is that the rational fixpoint of the functor FT , where T is a monad describing the branching of the systems (e.g. nondeterminism, weights, probability etc.), has as a quotient the rational fixpoint of the “determinised” type functor F̄ , a lifting of F to the category of T -algebras. We apply our framework to the concrete example of weighted automata, for which we present a new sound and complete calculus for weighted language equivalence. As a special case, we obtain non-deterministic automata, where we recover Rabinovich’s sound and complete calculus for language equivalence.
