THE NÉRON–SEVERI LIE ALGEBRA OF A SOERGEL MODULE

We introduce the Néron–Severi Lie algebra of a Soergel module and we determine it for a large class of Schubert varieties. This is achieved by investigating which Soergel modules admit a tensor decomposition. We also use the Néron–Severi Lie algebra to provide an easy proof of the well-known fact that a Schubert variety is rationally smooth if and only if its Betti numbers satisfy ...

Stochastic integer programming for multi-disciplinary outpatient clinic planning

Scheduling appointments in a multi-disciplinary clinic is complex, since coordination between disciplines is required. The design of a blueprint schedule for a multi-disciplinary clinic with open access requirements requires an integrated optimization approach, in which all appointment schedules are jointly optimized. As this currently is an open question in the literature, our ...

Using a Teaching Intervention and Calibrated Peer Review™ Diagnostics to Improve Visual Communication Skills

Rice University’s bioengineering department incorporates written, oral, and visual communication instruction into its undergraduate curriculum to aid student learning and to prepare students to communicate their knowledge and discoveries precisely and persuasively. In a tissue culture lab course, we used a self- and peer-review tool called Calibrated Peer Review™ (CPR) to diagnose ...

Video retrieval in laparoscopic video recordings with dynamic content descriptors

In the domain of gynecologic surgery an increasing number of surgeries are performed in a minimally invasive manner. These laparoscopic surgeries require specific psychomotor skills of the operating surgeon, which are difficult to learn and teach. This is the reason why an increasing number of surgeons promote checking video recordings of laparoscopic surgeries for the occurrence ...

A real time metabolomic profiling approach to detecting fish fraud using rapid evaporative ionisation mass spectrometry

Introduction Fish fraud detection is mainly carried out using a genomic profiling approach requiring long and complex sample preparations and assay running times. Rapid evaporative ionisation mass spectrometry (REIMS) can circumvent these issues without sacrificing a loss in the quality of results. Objectives To demonstrate that REIMS can be used as a fast profiling technique ...

Conventional and New Ways of Governing Forest Threats: A Study of Stakeholder Coherence in Sweden

Based on a framework for analyzing stakeholder coherence horizontally and vertically, the present study examined the governance of forest threats in Sweden. Opinions of forest risk governance in stakeholder groups with and without a connection to private forestry were compared (n = 2496) and the opinions were analyzed in relation to current governance practices. More specifically, ...

Parallelization of large vector similarity computations in a hybrid CPU+GPU environment

The paper presents design, implementation and tuning of a hybrid parallel OpenMP+CUDA code for computation of similarity between pairs of a large number of multidimensional vectors. The problem has a wide range of applications, and consequently its optimization is of high importance, especially on currently widespread hybrid CPU+GPU systems targeted in the paper. The following are ...

Preliminary Investigation of the Corrosion Behavior of Proprietary Micro-alloyed Steels in Aerated and Deaerated Brine Solutions

The corrosion performance of fairly new generation of micro-alloyed steels was compared in different concentrations of aerated and deaerated brines. Electrochemical polarization, weight loss and surface analyses techniques were employed. The results showed a threshold of corrosion rate at 3.5 wt.% NaCl in both aerated and deaerated solutions. The average corrosion current density ...

Magnetic, microwave absorption and structural properties of Mg–Ti added Ca–M hexaferrite nanoparticles

The Mg2+ and Ti4+ ions substituted M-type Ca(MgTi) x Fe12−2x O19 (x = 0, 0.3, 0.6, 0.9) hexagonal ferrites (x = 0, 0.3, 0.6, 0.9) were synthesized by the citrate sol–gel method. The microwave absorption, crystal structure, magnetic and morphology of the nanopowders were investigated with vector network analyzer, X-ray diffraction (XRD), vibrating sample magnetometer and ...

Rapid adaptation to near extinction in microbial experimental evolution

Theory indicates that responses to natural selection maximize immediate fitness benefits, leading to adaptations to current environmental conditions and those of the immediate past. Over a century of advances in theory, experiment, and observation have documented innumerable adaptations demonstrating the efficacy of natural selection to finely tune species to their respective ...

The Needs of Foster Children and How to Satisfy Them: A Systematic Review of the Literature

Family foster care deeply influences the needs of children and how these are satisfied. To increase our knowledge of foster children’s needs and how these are conceptualized, this paper presents a systematic literature review. Sixty-four empirical articles from six databases were reviewed and categorized (inter-rater agreement K = .78) into four categories: medical, belongingness, ...

Correction to: The U.S. Homeless Student Population: Homeless Youth Education, Review of Research Classifications and Typologies, and the U.S. Federal Legislative Response

The author regrets that typographical error occurred in values on page 702, second paragraph, lines 3 and 4. The correct values are $69.61 and $55.78. These values are corrected by this erratum. The lines should now read as, “EHCY’s federal appropriations in 2009 totaled $65,427,000 for 939,903 homeless students.”

Current and emerging treatment strategies for children with progressive chiasmatic-hypothalamic glioma diagnosed as infants: a web-based survey

Treatment of infant hypothalamic chiasmatic glioma (iCHG) is challenging, about 30% of the children progress during chemotherapy. Despite subsequent treatments the 5 year overall-survival rate is only 70%. This study investigates treatment strategies currently applied for progressive iCHG. A web-based questionnaire was sent out to the members of the SIOPE Brain Tumour Group asking ...
