Box spline prewavelets of small support

The purpose of this paper is the construction of bi- and trivariate prewavelets from box-spline spaces, \ie\ piecewise polynomials of fixed degree on a uniform mesh. They have especially small support and form Riesz bases of the wavelet spaces, so they are stable. In particular, the supports achieved are smaller than those of the prewavelets due to Riemenschneider and Shen in a recent, similar constructio

Reconstruction Algebras of Type D (I)

This is the second in a series of papers which give an explicit description of the reconstruction algebra as a quiver with relations; these algebras arise naturally as geometric generalizations of preprojective algebras of extended Dynkin diagrams. This paper deals with dihedral groups G=D_{n,q} for which all special CM modules have rank one, and we show that all but four of the relations on such a reconstruction algebra are given simply as the relations arising from a reconstruction algebra of type A. As a corollary, the reconstruction algebra reduces the problem of explicitly understanding the minimal resolution (=G-Hilb) to the same level of difficulty as the toric case.Comment: 31 pages, final versio

Richer but Resented: What do Cash Transfers do to Social Relations?

Cash transfers are an increasingly important component of social protection systems in most countries. Usually, cash transfers are evaluated against their effects on poverty or human capital, with their impact on social relations within and between households relegated to discrete comments on ‘stigma’, ‘resentment’ and sharing, including reduction of remittances and other support. Using evidence from Oxford Policy Management's evaluations of cash transfer programmes in Malawi and Zimbabwe, we suggest reconceptualising cash transfers as ongoing processes of intervention in a complex system of social relations. Cash transfer interventions operate through and affect this system at each stage: awareness?raising, targeting, payment, case management and monitoring and evaluation. We conclude that the impact of cash transfers on social relations is large and often negative. We argue that this is intrinsically important for wellbeing, but can also have negative consequences for material aspects of wellbeing, such as livelihoods

Qualitative characterization of a transesterification product of coconut oil by FIA-APCI-MS.

Synopsis Objectives The purpose of this work was the qualitative characterization of a recently transesterification product obtained from the coconut oil in the presence of polyglycerol-6 to produce a new PEG-free secondary surfactant. The purpose of a secondary surfactant is to reduce the harshness of a skin cleanser. Methods The transesterification product was qualitatively characterized in our laboratory by flow injection analysis-atmospheric pressure chemical ionization-mass spectrometry (FIA-APCI-MS). The mass spectrum of the transesterification product was compared to those of the starting materials (polyglycerol and coconut oil). Results The analyses highlighted the disappearance of the starting oil peaks and the appearance of new peaks assignable to the reaction products, mainly corresponding to diesters of polyglycerol. Additionally, peaks of unreacted polyglycerol are present as well as peaks of cyclization products derived from the polyglycerol starting material. Conclusions The development of this fast and easy analytical method, requesting only few minutes to be performed, represents a very useful tool for the characterization of transesterification products during the quality control of batches under production.Resume ObjectifsLe but de ce travail etait la caracterisation qualitative d'un produit de transesterification recemment obtenu a partir de l'huile de noix de coco en presence de polyglycerol-6 pour produire un nouveau tensioactif secondaire sans PEG, ce dernier generalement ajoute pour reduire l'agressivite d'un nettoyant pour la peau. MethodesLe produit de transesterification a ete qualitativement caracterise dans notre laboratoire par Analyse du Debit d'injection - par Ionisation chimique a Pression atmospherique - par Spectrometrie de masse (FIA-APCI-MS). Le spectre de masse du produit de transesterification a ete compare a ceux des materiaux de depart (de polyglycerol et d'huile de noix de coco). ResultatsLes analyses ont mis en evidence la disparition des pics d'huile de depart et l'apparition de nouveaux pics attribuables a des produits de reaction, correspondant principalement a des diesters de polyglycerol. De plus, les pics de polyglycerol non reagi sont presents ainsi que des pics de produits de cyclisation provenant de la matiere de depart de polyglycerol. ConclusionsLe developpement de cette methode d'analyse rapide et facile represente un outil tres utile pour la caracterisation des produits de transesterification pendant le controle de la qualite des lots en production

Approximation orders of shift-invariant subspaces of W2s(Rd)W^s_2({\Bbb R}^d)

We extend the existing theory of approximation orders provided by shift-invariant subspaces of $L_2$ to the setting of Sobolev spaces, provide treatment of $L_2$ cases that have not been covered before, and apply our results to determine approximation order of solutions to a refinement equation with a higher-dimensional solution space.Comment: 49 page

An Infrarenal Aortic Hypoplasia Presented with Claudication

We describe a case of infrarenal aortic hypoplasia in a 52-yr-old woman who presented with claudication. Computed tomographic angiography revealed an abrupt absence of the infrarenal aorta, with collateral flow reconstituting the iliofemoral systems. After a polytetrafluoroethylene graft was interposed between the aortic stump and the iliac bifurcation, the patient's claudication resolved

Cerebral cavernous malformations associated to meningioma: High penetrance in a novel family mutated in the PDCD10 gene

Multiple familial meningiomas occur in rare genetic syndromes, particularly neurofibromatosis type 2. The association of meningiomas and cerebral cavernous malformations (CCMs) has been reported in few patients in the medical literature. The purpose of our study is to corroborate a preferential association of CCMs and multiple meningiomas in subjects harbouring mutations in the PDCD10 gene (also known as CCM3). Three members of an Italian family affected by seizures underwent conventional brain Magnetic Resonance Imaging (MRI) with gadolinium contrast agent including gradient echo (GRE) imaging. The three CCM-causative genes were sequenced by Sanger method. Literature data reporting patients with coexistence of CCMs and meningiomas were reviewed. MRI demonstrated dural-based meningioma-like lesions associated to multiple parenchymal CCMs in all affected individuals. A disease-causative mutation in the PDCD10 gene (p.Gln112PhefsX13) was identified. Based on neuroradiological and molecular data as well as on literature review, we outline a consistent association between PDCD10 mutations and a syndrome of CCMs with multiple meningiomas. This condition should be considered in the differential diagnosis of multiple/familial meningioma syndromes. In case of multiple/familial meningioma the use of appropriate MRI technique may include GRE and/or susceptibility-weighted imaging (SWI) to rule out CCM. By contrast, proper post-gadolinium scans may aid defining dural lesions in CCM patients and are indicated in PDCD10-mutated individuals

Long-term recurrence and complication rates after incisional hernia repair with the open onlay technique

<p>Abstract</p> <p>Background</p> <p>Incisional hernia after abdominal surgery is a well-known complication. Controversy still exists with respect to the choice of hernia repair technique. The objective of this study was to evaluate the long-term recurrence rate as well as surgical complications in a consecutive group of patients undergoing open repair using an onlay mesh technique.</p> <p>Methods</p> <p>Consecutive patients undergoing open incisional hernia repair with onlay-technique between 01/05/1995 and 01/09/2007 at a single institution were included in the study. For follow-up patients were contacted by telephone, and answered a questionnaire containing questions related to the primary operation, the hernia and general risk factors. Patients were examined by a consultant surgeon in the outpatient clinic or in the patient's home if there was suspicion of an incisional hernia recurrence.</p> <p>Results</p> <p>The study included 56 patients with 100% follow-up. The median follow-up was 35 months (range 4–151). Recurrent incisional hernia was found in 8 of 56 patients (15%, 95% CI: 6–24). The overall complication rate was 13% (95% CI, 4–22). All complications were minor and needed no hospital admission.</p> <p>Conclusion</p> <p>This study with a long follow-up showed low recurrence and complication rates in patients undergoing incisional hernia repair with the open onlay technique.</p
