We consider the notion of a (<i>q,m)</i>-polymatroid, due to Shiromoto, and the more general notion of (<i>q,m</i>)-demi-polymatroids, and show how generalized weights can be defined for them. Further, we establish a duality for these weights analogous to Wei duality for generalized Hamming weights of linear codes. The corresponding results of Ravagnani for Delsarte rank metric codes, and Martínez-Peñas ...

We explicitly determine all the relative generalized Hamming weights of affine Cartesian codes using the notion of footprints and results from extremal combinatorics. This generalizes the previous works on the determination of relative generalized Hamming weights of Reed–Muller codes by Geil and Martin, as well as the determination of all the generalized Hamming weights of the affine Cartesian codes ...

Non-radiologist point-of-care ultrasonography (US) is increasingly implemented in paediatric care because it is believed to facilitate a timely diagnosis, such as in ascites or dilated renal pelvicalyceal systems, and can be used to guide interventional procedures. To date, all policy statements have been published by non-radiologic societies. The European Society of Paediatric Radiology hereby ...

<i>Background</i> - Chronic nonbacterial osteomyelitis (CNO) is a rare autoinflammatory bone disorder. Little information exists on the use of imaging techniques in CNO.<p> <p><i>Materials and methods</i> - We retrospectively reviewed clinical and MRI findings in children diagnosed with CNO between 2012 and 2018. Criteria for CNO included unifocal or multifocal inflammatory bone lesions, symptom ...

We classify all (locally) homogeneous Levi non-degenerate real hypersurfaces in C³ with symmetry algebra of dimension ≥6.

The complex and networked nature of sustainable procurement is evoked through confronting two conceptual models, the triple bottom line-inspired parallel-type “interlocking circles model” with the more systems-oriented series-type “concentric circles model”. This endeavor is integrated with a developed application of contingency theory rooted in network thinking. Two subcase narratives from Ghana, ...

I dette kapitlet presenterer og diskuterer vi hvordan kulturhistorisk aktivitetsteori kan fungere som tenkeredskap i aksjonsforskningsprosjekter. Nærmere bestemt så undersøker vi hvordan introduksjon av sentrale prinsipper i aktivitetsteori blir oppfattet og anvendt av deltagere på et doktorgradskurs om aksjonsforskning ved OsloMet – storbyuniversitetet. Det empiriske materialet er hentet fra ...

<i>Background and Aims</i> - Intestinal epithelial cells [IECs] secrete cytokines that recruit immune cells to the mucosa and regulate immune responses that drive inflammation in inflammatory bowel disease [IBD]. However, experiments in patient-derived IEC models are still scarce. Here, we aimed to investigate how innate immunity and IEC-specific pattern recognition receptor [PRR] signalling can be ...

The randomized “Testicular cancer and Aerobic and Strength Training trial” (TAST‐trial) aimed to evaluate the effect of high‐intensity interval training (HIIT) on cardiorespiratory fitness during cisplatin‐based chemotherapy (CBCT) for testicular cancer (TC). Here, we report on an unexpected high number of thromboembolic (TE) events among patients randomized to the intervention arm, and on a review ...

Early‐adulthood body size is strongly inversely associated with risk of premenopausal breast cancer. It is unclear whether subsequent changes in weight affect risk. We pooled individual‐level data from 17 prospective studies to investigate the association of weight change with premenopausal breast cancer risk, considering strata of initial weight, timing of weight change, other breast cancer risk ...
