The formation of the lunar farside highlands has long been an open problem in lunar science. We show that much of the topography and crustal thickness in this terrain can be described by a degree-2 harmonic. No other portion of the Moon exhibits comparable degree-2 structure. The quantified structure of ...

Structured observation is often used to evaluate handwashing behavior. We assessed reactivity to structured observation in rural Bangladesh by distributing soap containing acceleration sensors and performing structured observation 4 days later. Sensors recorded the number of times soap was moved. In 45 participating households, the median number of sensor soap ...

In open ecological systems, community structure can be determined by physically modulated processes such as the arrival of individuals from a regional pool and by local biological interactions. There is debate centering on whether niche differentiation and local interactions among species are necessary to explain macroscopic community patterns or whether ...

Mechanisms involved in post-fire morel fructification remain unclear. A new undescribed belowground vegetative structure of Morchella tomentosa in a burned boreal forest was investigated north of Fairbanks, Alaska. The name "radiscisclerotium" is proposed to define this peculiar and elaborate below-ground vegetative structure of M. tomentosa. Bayesian and maximum parsimony analyses ...

We show that inducing structural softness in regular magnetoelectric (ME) multiferroics-i.e., tuning the materials to make their structure strongly reactive to applied fields-makes it possible to obtain very large ME effects. We present illustrative first-principles results for BiFeO(3) thin films.

New protocols and instrumentation significantly boost the outcome of structural biology, which has resulted in significant growth in the number of deposited Protein Data Bank structures. However, even an enormous increase of the productivity of a single step of the structure determination process may not significantly shorten the time between ...

The Scottish Structural Proteomics Facility was funded to develop a laboratory scale approach to high throughput structure determination. The effort was successful in that over 40 structures were determined. These structures and the methods harnessed to obtain them are reported here. This report reflects on the value of automation but ...

The alar cartilages provide the contour and structural support of the nasal tip. Current rhinoplasty concepts support preservation of alar structure with suture techniques or judicious cephalic trim indicated for tip deformities. In many primary cases and some revisions, adequate alar structure exists to achieve the desired aesthetic and functional ...

In horses with chronic laminitis, an abnormal horn structure called the lamellar wedge develops within the lamellar region of the foot. This pathologic structure adversely affects normal foot function, and influences return to previous performance levels. Understanding the pathologic process that leads to the development of this structure is essential ...

Both structural and non-structural components can contribute to shoulder instability. Classification and therefore management must recognise these factors to achieve functional stability. This paper discusses a classification system proposing three types of shoulder instability recognising the structural and non-structural components and that a continuum exists between pathologies. Structural causes can ...

Polyglucosan bodies (Lafora bodies) were identified in a juvenile gray-headed flying fox (Pteropus poliocephalus) with neurological signs. The structures were only noted in the brain stem, and no associated degenerative changes were present. These structures have not been previously identified in any species in the order Chiroptera.

This is a combination of review and original data on floral structure and diversity in the two earliest diverging lineages of the Ericales, i.e. the balsaminoids, comprising Balsaminaceae, Marcgraviaceae and Tetrameristaceae, and the polemonioids, comprising Fouquieriaceae and Polemoniaceae. Each clade is strongly supported in molecular studies, while structural synapomorphies have ...

Cuts were performed with especially constructed device what enabled ideal cross-section without disturbing of structures of arachnoid of dura ...

Intraventricular tendons are structures that was identified more than a hundred years ago. It has been suggested that they represent intracavitary radiations of the bundle of His and that they may be an isolated finding or be associated with structural cardiac abnormalities.Loukas et al divided these structures into five categories ...

The structural, electronic, and mechanical properties of TaN were investigated by use of the density functional theory (DFT). Eight structures were considered, i.e., hexagonal WC, TaN, NiAs, wurtzite, and CoSn structures, cubic NaCl, zinc-blende and CsCl structures. The results indicate that TaN in TaN-type structure is the most stable at ...

We present a simple method for fast and precise replication of microfluidic master structures for moulding or soft embossing by double casting of microstructured masters with polydimethylsiloxane (PDMS). The significant achievement is a simple approach to inverse a given microstructure multiple times by means of PDMS-based soft lithography utilising hydroxypropylmethylcellulose ...

The ground states of Lennard-Jones clusters (LJ(n)) for sizes up to n = 147 are estimated as a function of the de Boer quantum delocalization length, Lambda, using the variational Gaussian wavepacket method. Consequently, the n-Lambda phase diagram is constructed showing the ranges of stability of various structural motifs, including ...

Mycoplasmas that are known to exhibit gliding motility possess a differentiated tip structure. This polar organelle mediates cytadherence and gliding motor activity and contains a cytoskeleton-like component that provides structural support. Here, we describe gliding motility and a unique cytoskeleton in Mycoplasma insons, which lacks any obviously differentiated tip structure.

Growing evidence suggests that structural feather colours honestly reflect individual quality or body condition but, contrary to pigment-based colours, it is not clear what mechanism links condition to reflectance in structural feather colours. We experimentally accelerated the moult speed of a group of blue tits (Cyanistes caeruleus) by exposing them ...

INTRODUCTION: Large-volume soft-tissue defects often leave exposed neurovascular and vital structures not amenable to immediate flap coverage. We describe the use of AlloDerm, an acellular dermis allograft, in providing temporary coverage of these structures in multistage reconstruction of the extremity. METHODS: A prospective study of 25 patients was performed using ...

As the largest predators of the Cambrian seas, the anomalocaridids had an important impact in structuring the first complex marine animal communities, but many aspects of anomalocaridid morphology, diversity, ecology, and affinity remain unclear owing to a paucity of specimens. Here we describe the anomalocaridid Hurdia, based on several hundred ...

In the first paper in this series of studies of the Helminthocladiaceae (Dory and Abbott, 1961 ), we have shown that, in two species of Helminthocladia from Hawaii, the female reproductive structures are generally similar to those described by other workers for other species in the genus, and that vegetative ...

Spatial structure has been identified as a major contributor to the maintenance of diversity. Here, we show that the impact of spatial structure on diversity is strongly affected by the ecological mechanisms maintaining diversity. In well-mixed, unstructured environments, microbial populations can diversify by production of metabolites during growth, providing additional ...

This paper is devoted to probabilistic models for concurrent systems under their true-concurrency seman- tics. Here we address probabilistic event structures. We consider a new class of event structures, called locally finite, that extend confusion-free event structure. In locally finite event structures, maximal configurations can be tiled with branching cells: ...

Trophic structure, or the distribution of biomass among producers and consumers, determines key ecosystem values, such as the abundance of infectious, harvestable or conservation target species, and the storage and cycling of carbon and nutrients. There has been much debate on what controls ecosystem trophic structure, yet the answer is ...

Because of the highly unique structures of marine natural products, there are many examples of structures that were originally proposed based on spectral analyses but later proven incorrect. In many cases, the total syntheses of the originally proposed structures of marine natural products has confirmed their incorrectness and the subsequent ...

From Structure to Urban Frames In the context of this thesis, the notion of frame is recognized as enclosing borders, or the outline of views, rather than as a load-bearing structural element. This thesis investigates how frames can build urban connections and, at the same time, structure sequences of movement ...

The larvae of Canthon cyanellus LeConte show well-defined sexual dimorphism. This dimorphism is seen in the presence of a terminal ampulla in the ventral region of the ninth abdominal segment in males. The terminal ampulla is a cuticular structure apparently present only in the male larvae beginning at the first ...

A new molecular oxide, [(IMo(7)O(26))(2)](6)(-), that has a self-contained structure has been synthesized. Its structural relevance both to the rutile structure and several molecular oxides that had been classified as "strange ones with odd structures" has given some insights as to why those species assume such structures. The novel yet ...
