A site for sori: Ecophysiology of fertile–sterile leaf dimorphy in ferns
Authors: Watkins James E. , Churchill Amber C. , Holbrook N. Michele 
Published: May 2016

PREMISE OF THE STUDY:Reproduction often requires significant investment and can move resources away from growth and maintenance; maintaining a balance between reproduction and growth can involve trade‐offs. Extreme functional specialization has separated reproduction and photosynthesis in most seed plants, yet ferns use the laminar surface of their fronds for both reproduction and photosynthesis. This dual function selects for a variety of frond morphologies that range from no specialization (monomorphy) to extreme dimorphy between fertile and sterile fronds (holodimorphy). Here we examined the ecological and physiological consequences of variation in frond dimorphy in ferns, evaluated reproductive trade‐offs across a dimorphy gradient, and speculate on factors controlling the occurrence of holodimorphy.METHODS:Ecophysiological measurements of photosynthetic rate, water potential, hydraulic conductivity, and gross morphological comparisons of frond area and angle were used to evaluate differences between fertile and sterile fronds. We examined three temperate and three tropical fern species that vary in degree of fertile–sterile dimorphy.KEY RESULTS:Holodimorphic species produced fewer fertile fronds, which had significantly higher respiratory rates than in sterile fronds on the same plant or in any frond produced on monomorphic species; hemidimorphic species were frequently intermediate. We found no differences in vulnerability to cavitation between fertile and sterile fronds. In dimorphic species, fertile fronds had higher (less negative) water potential and lower stipe hydraulic conductivity relative than in sterile fronds.CONCLUSIONS:Fertile–sterile dimorphy in ferns appears to come at considerable carbon cost in holodimorohic species. It is possible that the relative costs of this reproductive system are offset by increased spore dispersal, yet such trade‐offs require further exploration.

Published: May 2016

ABSTRACT

Objective:
To fully understand the original spatial position and three-dimensional (3D) anatomical morphology of cardiac skeleton (CS), and to quickly locate its position in patient-specific computed tomography angiography (CTA) images.

Materials and Methods:
First, we segmented and reconstructed 3D models of CS and its attached valves with Amira software, defined valve planes based on Chinese visible human 5 (CVH5), and then computed its geometric transformation matrix and applied them in locating the valve planes in patient-specific CTA images.

Results:
We reconstructed a 3D CS model based on CVH5 images which keep the original spatial position and its normal anatomical appearance. The 3D structures include aortic valve annulus (AVA), mitral valve annulus, tricuspid valve annulus, pulmonary valve annulus, and its attached valves. With the relative geometric transformation matrix, we quickly located the patient-specific valve planes that are vertical to each valve in CTA images.

Conclusions:
CVH5 dataset can be used in reconstructing the 3D model of CS, which is difficult for clinical images, such as CT, magnetic resonance imaging, and traditional anatomical method to achieve. Our method of 3D reconstruction presents more anatomical details than clinical images and keeps the original shape and position. We can define each valve plane on the CVH5 model and show its corresponding plane in patient-specific CTA images, which can be observed on each valve plane at the same time based on the consistent reference.
O sodobnem pomenu grške παιδεία za pojem uravnotežene vzgoje: Aristotel, Nietzsche, Camus, Hannah Arendt
Authors: Kalan Valentin 
Published: May 2016

Sodobni izobraževalni sistemi so v nenehnem procesu preurejanja, kar zahteva pozoren premislek osnov in zgradbe vzgoje in izobraževanja. Kaj je vzgoja in izobrazba ni mogoče pojasniti z definicijami, temveč samo v zgodovinski osmislitvi. Ta članek je prispevek k osvetlitvi sedanjega stanja izobraževanja ob navezavi na antično grško tradicijo. Izmed antičnih avtorjev je dana prednost Aristotelu, ker je njegova teorija vzgoje manj poznana, izmed sodobnih filozofov pa so predstavljeni Nietzsche, Camus in Hannah Arendt. Članek ima zato naslednjo členitev: 1. Fenomenološki pristop k Aristotelovi pedagogiki, 2. Nietzschejeve ideje o izobraževanju, 3. Albert Camus in njegova kritika evropskega nihilizma ob navezavi na grško antiko in 4. Hannah Arendt – izobraževanje kot priprava za nalogo obnavljanja našega skupnega sveta.
Med Avguštinovimi dialoškimi Samogovori in monološkimi Izpovedmi
Authors: Špelič Miran 
Published: May 2016

Članek pokaže na formalno in tematsko sorodnost med Avguštinovimi Samogovori in Izpovedmi. Prvo od teh del, ki je je ostalo nedokončano, je nastalo neposredno po spreobrnjenju (386), drugo pa okrog 15 let kasneje (400). Obe deli sta v obliki dialoga, vendar obakrat zelo svojskega. V prvem se dialog dogaja znotraj ene osebe, v drugem sogovornik navidez molči, vendar v resnici govori na zelo nenavaden način. Obe deli obravnavata osrednjo temo Avguštinove teologije, to je spoznavanje Boga in sebe, kar se tudi razvije v dvojnem razumevanju pojma confessio, »izpoved« (namreč izpoved grehov in hvale). Slednjič ponudimo hipotezo, da bi bil lahko eden od možnih namenov Izpovedi nadaljevanje odgovorov na vprašanja iz Samogovorov, ki so ostala še neodgovorjena.

O prisotnosti Mikencev na področju zahodne Anatolije, njenih obalah in otokih med začetkom 15. in koncem 12. stol. pr. n. št. pričajo arheološki viri. O naravi stikov med Hetiti in Mikenci na »periferiji« obeh kultur je (ob predpostavki, da v hetitskih besedilih izpričano ime Ahhiyawa označuje Mikence) mogoče sklepati na osnovi pisnih virov. Prispevek prinaša pregled in interpretacijo hetitskih besedil z omembami Ahhiyawe, arheoloških virov o Mikencih na področju Anatolije in Hetitih na področju Egejskega morja, nato shematično prikaže naravo stikov med Mikenci in Hetiti in opozori na vprašanja, ki jih identifikacija Ahhiyawe z mikenskim svetom prinaša.
Beda Častitljivi: Cerkvena zgodovina ljudstva Anglov. Prevod Bogdan Kolar in Miran Sajovic.

Published: May 2016

Z velikim projektom Celjske Mohorjeve družbe smo slovenski bralci leta 2015 dobili zapolnitev še ene bele lise v kulturi: prevod monumentalnega dela Historia ecclesiastica gentis Anglorum (v petih knjigah), ki ga je leta 731 v latinščini dokončal sveti Beda Častitljivi, menih iz Severne Humbrije na Angleškem. Delo se sicer začne z geografijo in zgodovino Britanije v rimskih časih, vendar postavlja v ospredje zgodovino razvoja krščanske Cerkve na Angleškem, zlasti v Severni Humbriji. Kljub poudarku na cerkveni zgodovini pa nam po uvodnih besedah enega od prevajalcev, dr. Bogdana Kolarja, delo ponuja tudi »največ informacij, ki nam pomagajo sestaviti zgodovino zgodnjih anglosaških kraljestev« (str. 47), torej največ splošnozgodovinskih podatkov o obravnavanem obdobju. To seveda ni bilo Bedovo edino delo; nasprotno, kot nam pove drugi prevajalec dr. Miran Sajovic v svojem uvodu, tvorijo večji del Bedovih spisov razlage svetopisemskih besedil, pridružujejo pa se jim Bedi zelo ljubi življenjepisi svetnikov, dve Kroniki človeške zgodovine, v katerih je uvedel štetje let »od Gospodovega učlovečenja«, torej po Kristusovem rojstvu, kot tudi homilije, priročniki (o metriki, retoričnih figurah, izračunavanju časa ...), pesmi (himne, epigrami) in peščica ohranjenih pisem. Najznamenitejša pa je vendarle Cerkvena zgodovina ljudstva Anglov.

Terminološka analiza korpusa starogrških medicinskih tekstov
Authors: Čengić Nina 
Published: May 2016

Lingvistična raziskava hipokratskih tekstov, utemeljena na modelnem pristopu analize diskurza, je razkrila vrsto specifičnih značilnosti, ki se udejanjajo formalni ravni in ki se jih da interpretirati kot karakteristike strokovnega diskurza hipokratske medicine. Formalne specifičnosti hipokratskega diskurza nastajajo deloma pod vplivom predsokratske filozofije (eksplanatorni modeli) in sofistov (retorične strategije), deloma pa se formirajo pod vplivom pravil javne komunikacije (prepričljivost, učinkovitost komunikacije, vloga publike), saj se strokovni medicinski diskurz udejanja kot eden izmed diskurzov javne domene v antični Grčiji.

Sinusitis Treatment Guideline Adherence in the e-visit Setting
Authors: Tran Dang , Westra Bonnie , Smith Kevin 
Published: May 2016

SummaryStudies demonstrate poor guideline adherence by health care providers for the treatment of upper respiratory infections, particularly acute bacterial rhinosinusitis (ABRS), in the appropriate prescribing of antibiotic medications.The purpose of this quality improvement project was to evaluate the effect of implementing interventions for improving adherence to a clinical practice guideline for the management of ABRS for patients treated in the e-visit setting. Interventions included: providing a report to providers of their adherence to the ABRS clinical guideline prior to the intervention, providing updated education on the ABRS guideline, and implementing a clinical decision support system reminder.A pre and post intervention evaluation design was used. Data were obtained from a retrospective electronic health record (EHR) data extract of all 316 diagnoses for ABRS in the preintervention 2-month time period and all 368 diagnoses of ABRS in the post-intervention 2-month time period. A review of the structured clinical data elements was performed to determine whether the provider adhered to the clinical guideline, meaning that only patients meeting the criteria for ABRS were to receive an antibiotic prescription.The interventions resulted in a 3.3% improvement in adherence to the ABRS clinical guideline from 95.25% adherence pre-intervention to 98.4% post-intervention. These results demonstrated that the use of an educational intervention and clinical decision support resulted in improved adherence to the ABRS clinical guideline in the e-visit setting. The implications for practice could be significant in that these quality improvement interventions improve guideline adherence and reduce unnecessary prescribing of antibiotics.
Investigation of metal contamination induced by a through silicon via reveal process using direct Si/Cu grinding and residual metal removal

Published: May 2016

Abstract
We investigated metal contamination induced by a through silicon via (TSV) reveal process using direct Si/Cu grinding and residual metal removal. A complementary metal oxide semiconductor (CMOS) wafer including TSVs was bonded to a glass support substrate, and a TSV reveal process was performed by direct Si/Cu grinding and residual metal removal. Then, metal contamination near the SiO2/Si interface on the front side of the wafer was investigated by using a pulsed-MOS capacitor technique and measuring the effective generation lifetime and effective surface generation velocity before and after this TSV reveal process. The results of Zerbst analysis showed that the changes in average effective generation lifetime and average effective surface generation velocity were −5.4 and +4.2%, respectively. These results demonstrate that the effect of metal contamination induced by our TSV reveal process on circuit components is small.
Radiative transfer in CO2‐rich atmospheres: 1. Collisional line mixing implies a colder early Mars
Authors: Ozak N. , Aharonson O. , Halevy I. 
Published: May 2016

AbstractFast and accurate radiative transfer methods are essential for modeling CO2‐rich atmospheres, relevant to the climate of early Earth and Mars, present‐day Venus, and some exoplanets. Although such models already exist, their accuracy may be improved as better theoretical and experimental constraints become available. Here we develop a unidimensional radiative transfer code for CO2‐rich atmospheres, using the correlated k approach and with a focus on modeling early Mars. Our model differs from existing models in that it includes the effects of CO2 collisional line mixing in the calculation of the line‐by‐line absorption coefficients. Inclusion of these effects results in model atmospheres that are more transparent to infrared radiation and, therefore, in colder surface temperatures at radiative‐convective equilibrium, compared with results of previous studies. Inclusion of water vapor in the model atmosphere results in negligible warming due to the low atmospheric temperatures under a weaker early Sun, which translate into climatically unimportant concentrations of water vapor. Overall, the results imply that sustained warmth on early Mars would not have been possible with an atmosphere containing only CO2 and water vapor, suggesting that other components of the early Martian climate system are missing from current models or that warm conditions were not long lived.
Streaming potential modeling in fractured rock: Insights into the identification of hydraulically active fractures
Authors: Roubinet D. , Linde N. , Jougnot D. , Irving J. 
Published: May 2016

AbstractNumerous field experiments suggest that the self‐potential (SP) geophysical method may allow for the detection of hydraulically active fractures and provide information about fracture properties. However, a lack of suitable numerical tools for modeling streaming potentials in fractured media prevents quantitative interpretation and limits our understanding of how the SP method can be used in this regard. To address this issue, we present a highly efficient two‐dimensional discrete‐dual‐porosity approach for solving the fluid flow and associated self‐potential problems in fractured rock. Our approach is specifically designed for complex fracture networks that cannot be investigated using standard numerical methods. We then simulate SP signals associated with pumping conditions for a number of examples to show that (i) accounting for matrix fluid flow is essential for accurate SP modeling and (ii) the sensitivity of SP to hydraulically active fractures is intimately linked with fracture‐matrix fluid interactions. This implies that fractures associated with strong SP amplitudes are likely to be hydraulically conductive, attracting fluid flow from the surrounding matrix.
Cone angle control of the interaction of magnetic clouds with the Earth's bow shock

Published: May 2016

AbstractWe study the interaction of magnetic clouds (MCs) with the near‐Earth environment. Recent works suggest that the bow shock crossing may modify significantly the magnetic structure of an MC, and thus its ability to drive geomagnetic storms. This change is largely controlled by the bow shock configuration, which depends on the upstream interplanetary magnetic field (IMF) orientation. From the distribution of the magnetic field orientation in 152 Earth‐impacting MCs, we determine for the first time the typical shock configuration during MC events. We find that 56% (6.3%) of the time, the subsolar bow shock configuration is exclusively quasi‐perpendicular (quasi‐parallel). The rest of the time, both configurations coexist. Furthermore, using a subset of 63 MCs observed simultaneously in the solar wind and in the dayside magnetosheath, we determine the magnitude of the magnetic field alteration, how it depends on the shock configuration, and how it relates to the IMF cone angle.
Stroke multiplicity and horizontal scale of negative charge regions in thunderclouds
Authors: Williams Earle R. , Mattos Enrique V. , Machado Luiz A. T. 
Published: May 2016

AbstractAn X‐band polarimetric radar and multiple lightning detection systems are used to document the initial cloud‐to‐ground lightning flash in a large number (46 cases) of incipient thunderstorms, as part of the CHUVA‐Vale field campaign during the 2011/2012 spring‐summer in southeast Brazil. The results show an exceptionally low stroke multiplicity (87% of flashes with single stroke) in the initial ground flashes, a finding consistent with the limited space available for the positive leader extension into new regions of negative space charge in compact cells. The results here are contrasted with the behavior of ground flashes in mesoscale thunderstorms in previous studies. Additionally, we found evidence for a minimum scale (radar echo >20 dBZ) for lightning initiation (>3 km in radius) and that the peak currents of initial cloud‐to‐ground flashes in these compact thunderstorms are only half as large as return stroke peak currents in general.
Dense bottom gravity currents and their impact on pelagic methanotrophy at oxic/anoxic transition zones
Authors: Schmale Oliver , Krause Stefan , Holtermann Peter , Power Guerra Nicole C. , Umlauf Lars 
Published: May 2016

AbstractWe show that inflows of oxygenated waters into sulfidic layers have a strong impact on biogeochemical transformation at oxic/anoxic transition zones. Taking the pelagic methane dynamics in the Gotland Basin as an example, we performed our studies when one of the largest inflows ever recorded entered the Baltic Sea in March 2015. An inflowing gravity current transported oxic waters into the sulfidic deep layers and freshly generated a near‐bottom secondary redox interface. At the upper slope, where the inflowing water masses were vigorously turbulent and the main and secondary redox interfaces in close contact to each other, methane oxidation rates inside the transition zone were found to be higher compared to the weakly turbulent basin interior. At the main redox interface in the basin center, lateral intrusions of oxygenated waters into intermediate water depth may have stimulated the growth of the methanotrophic community and their activity.
Hillslope‐derived blocks retard river incision
Authors: Shobe Charles M. , Tucker Gregory E. , Anderson Robert S. 
Published: May 2016

AbstractThe most common detachment‐limited river incision models ignore the effects of sediment on fluvial erosion, yet steep reaches of mountain rivers often host clusters of large (>1 m) blocks. We argue that this distribution of blocks is a manifestation of an autogenic negative feedback in which fast vertical river incision steepens adjacent hillslopes, which deliver blocks to the channel. Blocks inhibit incision by shielding the bed and enhancing form drag. We explore this feedback with a 1‐D channel‐reach model in which block delivery by hillslopes depends on the river incision rate. Results indicate that incision‐dependent block delivery can explain the block distribution in Boulder Creek, Colorado. The proposed negative feedback may significantly slow knickpoint retreat, channel adjustment, and landscape response compared to rates predicted by current theory. The influence of hillslope‐derived blocks may complicate efforts to extract base level histories from river profiles.
