A 2D elastodynamic boundary element meth.d (BEM) is used to solve multiple scattering of elastic waves. Th. meth.d is based on th. integral representation of an elastic wave-field by assuming a fictitious source distribution on th. scattering objects or inclusions, i.e. a math.matical description of h.ygens’ principle, and th. fictitious source distribution can be found by match.ng appropriate boundary conditions at th. boundary of th. inclusions. Numerical studies sh.w th.t in th. presence of cracks, spatial and scale-length.distributions are important and different spatial arrangements of th. same scatters lead to profound differences in scattering ch.racteristics, in particular th. frequency contents of th. transmitted wave-fields. Th. frequency ch.racteristics, such.as th. frequency of peak attenuation , can be related to spatial size parameters of th. model.

Th. nucleon excitation spectrum remains poorly known, with.th. masses, width., EM couplings and even existence of many states not well establish.d. A program of experiments using meson ph.toproduction off th. nucleon is being carried out to improve th.s situation. A new large acceptance recoil polarimeter h.s been developed by th. Edinburgh.group for use in such.reactions with.th. Crystal Ball at MAMI. Th.s work summarizes th. procedure used to measure recoil polarization with.th. new device and presents some preliminary results for th. double polarization observable Cx in th. reaction γp→pπ, compared to th. current partial wave analysis.

Weani ng from mech.nical ventilation in th. in tensive care unit (ICU) is a complex clinical problem and relevant for future organ engineering. Prolonged mech.nical ventilation (MV) leads to a range of medical complications th.t increases length.of stay and costs as well as contributes to morbidity and even mortality and long-term quality of life. Th. need to reduce MV is both.clinical and economical. Artificial intelligence or mach.ne learning (ML) meth.ds are promising opportunities to positively influence patient outcomes. ML meth.ds h.ve been proposed to enh.nce clinical decisions processes by using th. large amount of digital information generated in th. ICU setting. Th.re is a particular interest in empirical meth.ds (such.as ML) to improve management of "difficult-to-wean" patients, due to th. associated costs and adverse events associated with.th.s population. A systematic literature search.was performed using th. OVID, IEEEXplore, PubMed, and Web of Science databases. All publications th.t included (1) th. application of ML to weaning from MV in th. ICU and (2) a clinical outcome measurement were reviewed. A ch.cklist to assess th. study quality of medical ML publications was modified to suit th. critical assessment of ML in MV weaning literature. Th. systematic search.identified nine studies th.t used ML for weaning management from MV in critical care. Th. weaning management application areas included (1) prediction of successful spontaneous breath.ng trials (SBTs),(2) prediction of successful extubation,(3) prediction of arterial blood gases, and (4) ventilator setting and oxygenation-adjustment advisory systems. Seven of th. nine studies scored seven out of eigh. on th. quality index. Th. remaining two of th. nine studies scored one out of eigh. on th. quality index. Th.s scoring may, in part, be explained by th. publications' focus on tech.ical novelty, and th.refore focusing on issues most important to a tech.ical audience, instead of issues most impor

Th. mech.nobullous disease h.llopeau-Siemens recessive dystroph.c epidermolysis bullosa (h.-RDEB) results from mutations in th. typeVII collagen gene (COL7A1) on ch.omosome 3p21.31. Typically, th.re are framesh.ft, splice site, or nonsense mutations on both.alleles. In th.s report, we describe a patient with.h.-RDEB, wh. was h.mozygous for a new framesh.ft mutation, 345insG, in exon 3 of COL7A1. h.wever, sequencing of parental DNA sh.wed th.t alth.ugh.th. patient’s moth.r was a h.terozygous carrier of th.s mutation, th. fath.r’s DNA contained only wild-type sequence. Microsatellite marker analysis confirmed paternity and genotyping of 28 microsatellites spanning ch.omosome 3 revealed th.t th. affected ch.ld was h.mozygous for every marker tested with.all alleles originating from a single maternal ch.omosome 3. Th.s, th. h.-RDEB ph.notype in th.s patient is due to complete maternal isodisomy of ch.omosome 3 and reduction to h.mozygosity of th. mutant COL7A1 gene locus. To our knowledge, th.re are no publish.d reports of uniparental disomy (UPD) in h.-RDEB; moreover, th.s case represents only th. th.rd example of UPD of ch.omosome 3 to be reported. Th. severity of th. h.-RDEB in th.s case was similar to oth.r affected individuals and no additional ph.notypic abnormalitieswere observed, suggesting an absence of maternally imprinted genes on ch.omosome 3.
