Decomposable approximations of nuclear <i>C</i>^*-algebras

We show that nuclear &lt;i&gt;C&lt;/i&gt;&lt;sup&gt;*&lt;/sup&gt;-algebras have a refined version of the completely positive approximation property, in which the maps that approximately factorize through finite dimensional algebras are convex combinations of order zero maps. We use this to show that a separable nuclear &lt;i&gt;C&lt;/i&gt;&lt;sup&gt;*&lt;/sup&gt;-algebra A which is closely contained in a &lt;i&gt;C&lt;/i&gt;&lt;sup&gt;*&lt;/sup&gt;-algebra B embeds into B

Solar energy in buildings: Implications for California energy policy

An assessment of the potential of active solar energy systems for buildings in California is summarized. The technology used for solar heating, cooling, and water heating in buildings is discussed. The major California weather zones and the solar energy designs are described, as well as the sizing of solar energy systems and their performance. The cost of solar energy systems is given both at current prices and at prices consistent with optimistic estimates for the cost of collectors. The main institutional barriers to the wide spread use of solar energy are summarized

Building application of solar energy. Study no. 4: Scenarios for the utilization of solar energy in southern California buildings, change 1

Plausible future market scenarios for solar heating and cooling systems into buildings in the area served by the Southern California Edison Company. A range of plausible estimates for the number of solar systems which might be installed and the electrical energy which might be displaced by energy from these systems are provided. The effect on peak electrical load was not explicitly calculated but preliminary conclusions concerning peak load can be inferred from the estimates presented. Two markets are investigated: the single family market and the large power commercial market

Decomposable approximations of nuclear C*-algebras

We show that nuclear C*-algebras have a re ned version of the completely positive approximation property, in which the maps that approximately factorize through finite dimensional algebras are convex combinations of order zero maps. We use this to show that a separable nuclear C*-algebra A which is closely contained in a C*-algebra B embeds into B

Association of left ventricular longitudinal strain with central venous oxygen saturation and serum lactate in patients with early severe sepsis and septic shock

Syftet med denna studie är att synliggöra pedagogers syn på föräldrasamverkan i förskolan. Vi har även intresserat oss på samverkan mellan pedagogerna och föräldrar med annat modersmål än svenska. Vår studie grundar sig på observationer kring bemötande av föräldrar på förskolan. Vi undersökte hur pedagogerna såg på föräldrasamverkan och hur de arbetar kring samverkan med föräldrar, för att kunna få en bredare syn i vår studie om hur samverkan fungerar på de aktuella förskolorna. Som metod använde vi kvalitativ intervju då detta lämpade sig väl för oss för att vi skulle kunna få en bredare syn om hur samverkan fungerar på de aktuella förskolorna. Intervjuer ger mer exakta svar och det underlättar för oss som intervjuar att ställa följdfrågor. Resultatet visar att samverkan med föräldrar har ökat i förskolan och blivit en stor del av verksamheten. Pedagogerna försöker engagera sig mycket i arbetet med föräldrasamverkan och letar efter möjligheter för att skapa en bra kommunikation med föräldrar som har annat modersmål än svenska. Resultaten visar även att pedagogerna menar att oavsett om föräldrarna behärskar det svenska språket eller inte så anstränger de sig för att visa föräldrarna att de är viktiga i verksamheten

Lung adenocarcinoma presenting as a solitary gingival metastasis: a case report

<p>Abstract</p> <p>Introduction</p> <p>Gingival metastases are very rare and generally occur in disseminated tumors. We report a case of solitary gingival metastasis of lung cancer.</p> <p>Case presentation</p> <p>We report the case of a 74-year-old asymptomatic Caucasian woman affected by a rapidly growing, painless gingival swelling. Histopathologic examination of the excisional biopsy showed metastasis of poorly differentiated thyroid transcription factor 1-positive adenocarcinoma. A total-body computed tomographic scan revealed a tumor of the right lung lower lobe with ipsilateral, mediastinal lymph node swelling. Moreover, bone scintigraphy revealed no bone metastases. No other metastases were found, so we planned a multi-modal therapeutic approach with a curative intent. However, the tumor proved to be intrinsically resistant and highly aggressive.</p> <p>Conclusion</p> <p>The presentation of solitary gingival metastasis is exceptional. In view of its rapid clinical evolution, our case confirms that gingival metastasis is an important prognostic factor. This behavior raises the question whether the poor prognosis for patients with tumors with oral metastases depends on its diffuse spread or on its highly malignant nature.</p

A Simple Separable Exact C*-Algebra not Anti-isomorphic to Itself

We give an example of an exact, stably finite, simple. separable C*-algebra D which is not isomorphic to its opposite algebra. Moreover, D has the following additional properties. It is stably finite, approximately divisible, has real rank zero and stable rank one, has a unique tracial state, and the order on projections over D is determined by traces. It also absorbs the Jiang-Su algebra Z, and in fact absorbs the 3^{\infty} UHF algebra. We can also explicitly compute the K-theory of D, namely K_0 (D) = Z[1/3] with the standard order, and K_1 (D) = 0, as well as the Cuntz semigroup of D.Comment: 16 pages; AMSLaTeX. The material on other possible K-groups for such an algebra has been moved to a separate paper (1309.4142 [math.OA]

The Index of (White) Noises and their Product Systems

(See detailed abstract in the article.) We single out the correct class of spatial product systems (and the spatial endomorphism semigroups with which the product systems are associated) that allows the most far reaching analogy in their classifiaction when compared with Arveson systems. The main differences are that mere existence of a unit is not it sufficient: The unit must be CENTRAL. And the tensor product under which the index is additive is not available for product systems of Hilbert modules. It must be replaced by a new product that even for Arveson systems need not coincide with the tensor product

Appealing avatars from 3D body scans: Perceptual effects of stylization

Advances in 3D scanning technology allow us to create realistic virtual avatars from full body 3D scan data. However, negative reactions to some realistic computer generated humans suggest that this approach might not always provide the most appealing results. Using styles derived from existing popular character designs, we present a novel automatic stylization technique for body shape and colour information based on a statistical 3D model of human bodies. We investigate whether such stylized body shapes result in increased perceived appeal with two different experiments: One focuses on body shape alone, the other investigates the additional role of surface colour and lighting. Our results consistently show that the most appealing avatar is a partially stylized one. Importantly, avatars with high stylization or no stylization at all were rated to have the least appeal. The inclusion of colour information and improvements to render quality had no significant effect on the overall perceived appeal of the avatars, and we observe that the body shape primarily drives the change in appeal ratings. For body scans with colour information, we found that a partially stylized avatar was most effective, increasing average appeal ratings by approximately 34%
