- We consider the following third-order differential equation with unbounded coefficients:Some new existence and uniqueness results are proved, and precise estimates of the norms of the solutions are given. The obtained results may be regarded as a unification and extension of all other results of this type

Prospective analysis of intrinsic and extrinsic risk factors on the development of Achilles tendon pain in runners

- There are currently no generally accepted, consistent results that clearly characterize factors causing Achilles tendon pain (AT) in runners. Therefore, we carried out a prospective study to evaluate the multifactorial influence of clinical, biomechanical (isometric strength measurements and three-dimensional kinematics) and training-related risk factors on the development of AT. Two hundred sixty-nine uninjured runners were recruited and underwent an initial examination. One hundred forty-two subjects completed their participation by submitting training information on a weekly basis over a maximal period of 1 year. Forty-five subjects developed an overuse injury, with 10 runners suffering from AT. In an uninjured state, AT runners already demonstrated decreased knee flexor strength and abnormal lower leg kinematics (sagittal knee and ankle joint) compared with a matched control group. A relationship between years of running experience or previous overuse injuries and the development of new symptoms could not be established. The interrelationship of biomechanical and training-specific variables on the generation of AT is evident. A combination of alterations in lower leg kinematics and higher impacts caused by fast training sessions might lead to excessive stress on the Achilles tendon during weight bearing and thus to AT in recreational runners.

Crossing the dripline to N-11 using elastic resonance scattering
- 2000

Ingår i: Physical Review C - Nuclear Physics. - 2469-9985 .- 2469-9993. ; 6203:3

Tidskriftsartikel (refereegranskat)abstract
- The level structure of the unbound nucleus N-11 has been studied by C-10+p elastic resonance scattering in inverse geometry with the LISE3 spectrometer at GANIL, using a C-10 beam with an energy of 9.0 MeV/ nucleon. An additional measurement was done at the A1200 spectrometer at MSU. The excitation function above the C-10+p threshold has been determined up to 5 MeV. A potential-model analysis revealed three resonance states at energies 1.27(-0.05)(+0.18) MeV (Gamma = 1.44 +/- 0.2 MeV), 2.01(-0.05)(+0.15) MeV (Gamma = 0.84 +/- 0.2 MeV), and 3.75 +/- 0.05 MeV (Gamma = 0.60 +/- 0.05 MeV) with the spin-parity assignments I-pi=1/2+,1/2,-,5/2+, respectively. Hence, N-11 is shown to have a ground state parity inversion completely analogous to its mirror partner Be-11. A narrow resonance in the excitation function at 4.33 +/- 0.05 MeV was also observed and assigned spin parity 3/2-.

Restitution of ability and difficulty from decision-making : The metrology of human-based perceptions
- 2018

Konferensbidrag (refereegranskat)abstract
- Fundamental reappraisal of metrology, beyond superficial analogies with traditional measurement instruments, is needed if ordinal properties – such as ‘counted fractions’ (bounded by zero and one), performance metrics for ability tests, customer satisfaction, etc - are to be included in an extended quantity calculus for a new SI. Regarding a human being (or other ‘probe’) as a Measurement Instrument with Rasch measurement theory (i.e., postulating a Generalised Linear Model link function z = θ – δ, of a ‘probe’ attribute θ and a ‘target’ attribute δ) not only handles ordinal properties of the measurement system response, Psuccess, but also attribute separability in restitution; essential to underpinning measurement traceability and uncertainty. Examples from person-centred care (e.g., of Alzheimer ’s disease patients) will demonstrate causal Rasch models relating task difficulty and patient ability to explanatory variables such as test sequence entropy and brain atrophy, thereby enabling novel certified reference materials for traceability.

Antibiotics and Carbohydrate-Containing Drugs Targeting Bacterial Cell Envelopes : An Overview
- 2022
-
Ingår i: Pharmaceuticals. - : MDPI AG. - 1424-8247. ; 15:8

Forskningsöversikt (refereegranskat)abstract
- Certain bacteria constitute a threat to humans due to their ability to escape host defenses as they easily develop drug resistance. Bacteria are classified into gram-positive and gram-negative according to the composition of the cell membrane structure. Gram-negative bacteria have an additional outer membrane (OM) that is not present in their gram-positive counterpart; the latter instead hold a thicker peptidoglycan (PG) layer. This review covers the main structural and functional properties of cell wall polysaccharides (CWPs) and PG. Drugs targeting CWPs are discussed, both noncarbohydrate-related (β-lactams, fosfomycin, and lipopeptides) and carbohydrate-related (glycopeptides and lipoglycopeptides). Bacterial resistance to these drugs continues to evolve, which calls for novel antibacterial approaches to be developed. The use of carbohydrate-based vaccines as a valid strategy to prevent bacterial infections is also addressed.
