description: Recreational clam digging is a traditional activity on the large intertidal zone of the western coasts of the Cotentin (western English Channel). A variety of fishing gears are used to harvest the target species the warty venus Venus verrucosa (Linnaeus, 1758). In this note, the immediate effect (i.e., four days) of fork harvesting was studied during the March 2012 spring tide, following a control-impact design with a control station and three impacted stations using pebble forks. An immediate significant decreases of coarse sand and gravel benthic macrofauna is observed in fishing area. In the future, it is recommended that pebble fork fishing should be prohibited to harvest this target species.

Racial inequalities

description: Western studies have established that men from African descent are disproportionally affected by prostate cancer (PCa). Annual incidence rates in this population vary from 1.5 to 2 times when compared to their counterparts from other racial groups. They also record the worse outcomes in terms of prognosis. Additionally, with the rise of PCa in Subsaharan Africa, new cancer control policies and programs are increasingly demanded. Understanding therefore, factors that underpin racial inequality in distribution and especially why the disease preferentially niches in African males can help better address PCa in both Western and Subsaharan countries. There is also the potential to develop new therapeutic options. A genetic susceptibility was first hypothesized, however available data suggest that they only account for less than 20% of the cases. Current findings from epidemiological and molecular investigations suggest an important role of complex and dynamic environmental interactions involving the different levels of calcium regulation. Using a multi-method design, this research aims at developing an integrative mechanistic model of PCa. We argue that given the versatile and ubiquitous role calcium plays in nutrition, physical environment, and in key cellular processes, that mineral cation is central to prostate tumorigenesis and in shaping its populational distribution. Thus a tree-level investigation was conducted: (i) a critical analysis and synthesis of empirical evidence on calcium interactions with cancer mechanisms (ii) a population-wide prospective cohort study of calcium intake patterns in a group of Subsaharan males in Côte d’Ivoire, namely the African Prostate Cancer Study (APCS) (iii) a proteomics research investigating the responses of prostate cancer cell lines when exposed to a high affinity synthetic calcium binding peptide. This monograph describes the research methods, instruments design and validation and the preliminary findings of the ongoing research, portions of which have already been published, presented at two international cancer seminars or under review. Findings at this stage include: mechanistic models of prostate cancer differential distribution and outcomes, a novel calcium questionnaire specific to African diet, synthesis of a high affinity calcium-binding peptide (Peptide#1). New concepts and constructs related to prostatic carcinogenesis have been developed as well.

description: We have measured the absorption of terahertz radiation in a BCS superconductor over a broad range of frequencies from 200 GHz to 1.1 THz, using a broadband antenna-lens system and a tantalum microwave resonator. From low frequencies, the response of the resonator rises rapidly to a maximum at the gap edge of the superconductor. From there on the response drops to half the maximum response at twice the pair-breaking energy. At higher frequencies, the response rises again due to trapping of pair-breaking phonons in the superconductor. In practice this is the first measurement of the frequency dependence of the quasiparticle creation efficiency due to pair-breaking in a superconductor. The efficiency, calculated from the different non-equilibrium quasiparticle distribution functions at each frequency, is in agreement with the measurements.

description: The use of recycled concrete aggregates (RCA) has gained increased attention in the past few decades as an alternative to decrease the carbon footprint of concrete construction. Yet, most of the research performed so far demonstrates that RCA concrete displays inferior performance in the fresh and hardened states when compared to conventional concrete (CC). The latter is believed due to the fact that very often the different microstructure of RCA is not accounted for while the mix-proportioning of RCA concrete. Recently, a number of mix-design procedures accounting for RCA microstructure have been proposed. Amongst them, the Equivalent Volume (EV) method seems to be quite promising. The EV method may proportion RCA concrete made of coarse (CRCA) or fine (FRCA) RCA and is based on a companion CC. Previous research has demonstrated that the fresh and hardened properties of EV mix-designed CRCA are suitable for structural applications. Yet, very few research, analysis and quantification have been conducted on the fresh behaviour of EV mix- proportioned FRCA concrete. This work presents a comprehensive study on the rheological behaviour of EV mix-designed CRCA and FRCA concrete presenting distinct features (i.e. inner qualities, mineralogy, fabrication process, etc.) through the use of a planetary rheometer (IBB). Results show that the EV is capable of proportioning low embodied energy CRCA and FRCA concrete with shear thinning profiles. The latter suggests that these mixtures are suitable for applications under high torque regimes such as vibrated or pumped concrete.
Laser based material processing for medical and biotechnology applications

Year: 2022

description: At the Medical Laser Center Lübeck, various laser systems with wavelength ranging from deep UV to infrared are available for micro material processing. Excimer Lasers are a versatile tool in many material processing applications. Due to their short attenuation length in many materials, the applied energy is absorbed near the surface. This leads to a process called ‘cold ablation’ which allows material processing on a sub-micrometer scale in axial direction, with minimal unwanted thermal effects. This could be interesting for post processing of surfaces of objects made in 3D printing. Polymers, ceramics and biological tissue are examples of materials processed with excimer lasers. We mainly use processes like drilling, milling or selective ablation in the fabrication of microfluidic devices and modification of polymer membranes. Ultra-short pulse lasers operate in a range of pico- to femtoseconds pulse duration. This type of laser allows high resolution structuring of nearly every material at high speed rates. Currently we are using USP Laser for generating so called Laser-induced periodic surface structures (LIPSS). Upon irradiation with ultra-short pulses, nano-structures with adaptable characteristics begin to form on the surface. With the right parameter set these structures can act as ‘light traps’, letting the surface appear blackened with high contrast or modify the material for better cell adhesion. Among others, applications are blackmarking on surgical instruments or generation of functional surfaces for e.g. cell- and biological applications. Nanosecond Microchip Laser can be an effective, low cost alternative to ultra-short pulse lasers for processes like cutting or marking. Using ns-Lasers, we developed processes for visible markings inside transparent materials, achieved through optical breakdown and label microscopic slides with alpha numeric symbols and 2D codes.

Social Media Portrayals of Three Extractives Companies’ Funding of Sport for Development in Indigenous Communities in Canada and Australia

description: The extractives industry (mining, oil, and gas) engages in corporate social responsibility (CSR) activities to reinforce its organizational legitimacy and enhance its public image. One such approach to CSR that is popular in the industry is through funding sport initiatives aimed at Indigenous peoples (often termed Sport for Development; SFD). On the surface, such funding may seem commendable and innocuous; however, questions have been raised about the ways in which such funding may obfuscate the harmful impacts that the extractives industry has had and continues to have on Indigenous peoples and their traditional territories. Through the adoption of a postcolonial theoretical perspective and in conjunction with netnographic methods and discourse analysis, this project involved a consideration of how extractives companies portray their funding of sport programs in Indigenous communities on social media. Given the research focus on Indigenous communities in the countries known as Canada and Australia, between country differences were also examined. Three discourses related to the extractives industry’s funding of SFD in Indigenous communities in Canada and Australia were developed. These discourses included the following: 1) Extractives companies are proud “partners” of Indigenous communities; 2) Extractives companies are committed to helping Indigenous communities in Canada and Australia; and 3) Canadian extractives companies are future focused and past-blind, while Australian extractives companies are advocates for reconciliation. Overall, extractives companies in Canada and Australia were found to use social media to portray themselves as responsible and committed partners of Indigenous communities, while obscuring the ongoing histories of colonialism through discourses of empowerment and development through sport. Suggestions are made regarding ongoing interrogation of the ways in which the extractives industry perpetuates colonialism.
Insulation of the conduction pathway of muscle transverse tubule calcium channels from the surface charge of bilayer phospholipid
Creators: name: Coronado, Roberto

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: Functional calcium channels present in purified skeletal muscle transverse tubules were inserted into planar phospholipid bilayers composed of the neutral lipid phosphatidylethanolamine (PE), the negatively charged lipid phosphatidylserine (PS), and mixtures of both. The lengthening of the mean open time and stabilization of single channel fluctuations under constant holding potentials was accomplished by the use of the agonist Bay K8644. It was found that the barium current carried through the channel saturates as a function of the BaCl2 concentration at a maximum current of 0.6 pA (at a holding potential of 0 mV) and a half-saturation value of 40 mM. Under saturation, the slope conductance of the channel is 20 pS at voltages more negative than -50 mV and 13 pS at a holding potential of 0 mV. At barium concentrations above and below the half-saturation point, the open channel currents were independent of the bilayer mole fraction of PS from XPS = 0 (pure PE) to XPS = 1.0 (pure PS). It is shown that in the absence of barium, the calcium channel transports sodium or potassium ions (P Na/PK = 1.4) at saturating rates higher than those for barium alone. The sodium conductance in pure PE bilayers saturates as a function of NaCl concentration, following a curve that can be described as a rectangular hyperbola with a half-saturation value of 200 mM and a maximum conductance of 68 pS (slope conductance at a holding potential of 0 mV). In pure PS bilayers, the sodium conductance is about twice that measured in PE at concentrations below 100 mM NaCl. The maximum channel conductance at high ionic strength is unaffected by the lipid charge. This effect at low ionic strength was analyzed according to J. Bell and C. Miller (1984. Biophysical Journal. 45:279- 287) and interpreted as if the conduction pathway of the calcium channel were separated from the bilayer lipid by approximately 20 A. This distance thereby effectively insulates the ion entry to the channel from the bulk of the bilayer lipid surface charge. Current vs. voltage curves measured in NaCl in pure PE and pure PS show that similarly small surface charge effects are present in both inward and outward currents. This suggests that the same conduction insulation is present at both ends of the calcium channel.
Interactions of lithium and protons with the sodium-proton exchanger of dog red blood cells
Creators: name: Parker, John C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: Passive movements of Li in dog red blood cells (RBC) ar like those of Na and protons in being stimulated by osmotic cell shrinkage and inhibited by amiloride. Li and protons have similar asymmetrical effects on Na-H exchange. When the intracellular fluid is made rich in Li or protons, Na-H exchange is stimulated. When the extracellular fluid is enriched in Li or protons, Na-H exchange is inhibited. In the case of protons, these effects can override alterations in driving force that are created by the experimental conditions. For example, acidification of the cytoplasm stimulates outward Na movements, while acidification of the medium inhibits Na efflux. Thus, protons (and, by analogy, Li) can interact with the Na-H exchanger not only as substrates but also as modulators. In previous experiments, the only way to activate the Na-H exchanger in dog RBC was to shrink the cells in hypertonic media. The influences of Li or protons, however, are so strong as to preempt the volume effects, so that the pathway can be activated even in swollen cells and deactivated in shrunken ones.

Single channel measurements of the calcium release channel from skeletal muscle sarcoplasmic reticulum. Activation by Ca2+ and ATP and modulation by Mg2+

description: A high-conductance (100 pS in 53 mM trans Ca2+) Ca2+ channel was incorporated from heavy-density skeletal muscle sarcoplasmic reticulum (SR) fractions into planar lipid bilayers of the Mueller-Rudin type. cis Ca2+ in the range of 2-950 microM increased open probability (Po) in single channel records without affecting open event lifetimes. Millimolar ATP was found to be as good as or better than Ca2+ in activation; however, both Ca2+ and ATP were required to fully activate the channel, i.e., to bring Po = 1. Exponential fits to open and closed single channel lifetimes suggested that the channel may exist in many distinct states. Two open and two closed states were identified when the channel was activated by either Ca2+ or ATP alone or by Ca2+ plus nucleotide. Mg2+ was found to permeate the SR Ca channel in a trans-to- cis direction such that iMg2+/iCa2+ = 0.40. cis Mg2+ was inhibitory and in single channel recordings produced an unresolvable flickering of Ca- and nucleotide-activated channels. At nanomolar cis Ca2+, 4 microM Mg2+ completely inhibited nucleotide-activated channels. In the presence of 2 microM cis Ca2+, the nucleotide-activated macroscopic Ba conductance was inhibited by cis Mg2+ with an IC50 equal to 1.5 mM.

description: Critical-sized bone defects can result from trauma, inflammation, and tumor resection. Such bone defects, often have irregular shapes, resulting in the need for new technologies to produce suitable implants. 3D printing is an additive manufacturing method to create complex and individualized bone constructs, which can be seeded with autologous cells from the patients. In this study, we established an extrusion-based printing technology to produce osteoinductive scaffolds based on biocompatible polycaprolactone (PCL) combined with calcium phosphate (CA) [1], [2]. The internal structure of the scaffolds resembles a bone-like spongiosa with irregular interconnected pores (diameter: 2mm +/- 0.2 mm SD), whereas the outer shape is a ring with a diameter of 20 mm and a height of 10 mm. The scaffold was printed using the thermoplastic PCL or PCL-CA and a BIO X6 printer. To produce the printing material, PCL was combined with calcium phosphate nano powder (> 150 nm particle size) under heating. After printing, 5 x 106 MG63 (osteosarcoma cell line) were seeded on the constructs using a rotating incubator for 24 hours. This extrusion-based printing process has the ability to create a construct with a bone-like mechanical stability. Mechanical properties are under investigation. In first studies the integrated calcium phosphate shows an influence on the gene expression of the osteogenic differentiation markers (collagen-1, osteocalcin) and the adhesion marker integrin-ß1 in MG63 cells. The MG63 cells attach to the PCL and the PCL CA and proliferate over the investigated time frame (14 days) as indicated by DNA quantification. An increase of the cell density is also visible by confocal laser scanning microscopy, after the cytoskeleton of the cells was stained with Phalloidin TRITC and Hoechst as nuclear counter stain. The actin cytoskeleton visualizes the elongated morphology of the cell, also shown by electron microscopy pictures, which also depicts the material surfaces. The porous PCL ring could serve as an outer matrix for the implant, providing construct stability similar to natural bone.

description: While bare diagrammatic series are merely Taylor expansions in powers of interaction strength, dressed diagrammatic series, built on fully or partially dressed lines and vertices, are usually constructed by reordering the bare diagrams, which is an a priori unjustified manipulation, and can even lead to convergence to an unphysical result [Kozik, Ferrero and Georges, PRL 114, 156402 (2015)]. Here we show that for a broad class of partially dressed diagrammatic schemes, there exists an action $S^{(ξ)}$ depending analytically on an auxiliary complex parameter $ξ$, such that the Taylor expansion in $ξ$ of correlation functions reproduces the original diagrammatic series. The resulting applicability conditions are similar to the bare case. For fully dressed skeleton diagrammatics, analyticity of $S^{(ξ)}$ is not granted, and we formulate a sufficient condition for converging to the correct result.

A review of predators and predation at deep-sea hydrothermal vents
Creators: name: VOIGHT, Janet R.
Publisher: name: Station Biologique de Roscoff (SBR)
Year: 2000

description: The very few predators at deep-sea hydrothermal vents have been hypothesized to allow extremely vulnerable,
 relic taxa to survive in these habitats. If vents are viewed as ephemeral habitats in which disturbance is so frequent that few
 endemic predators can survive, their scarcity, rather than being an anomaly, is seen as a logical consequence of habitat
transience. Toxins, however, may minimize exploitation of the habitat by most opportunistic predators.
 Rates of lethal predation remain undetermined, but vent limpets and vestimentiferans, including those from areas with
 high sulphide levels, show frequent evidence of non-lethal predation.
 Characterizing vent habitats as unchanged over geological time and as home to "relic" taxa of ancient groups ignores
historic anoxic episodes and the increasing fossil history of vent assemblages. Although trophic relations of vent predators
 remain poorly known, deep-sea predators are more diverse both taxonomically and in their foraging habits than had been
 expected; the reportedly vulnerable vent fauna may show unsuspected defenses.
 Variation in Carbon and Nitrogen isotopes among chemosynthetic taxa and bacteria complicates isotope analyses which
 are most powerful when supplemented by direct observations and specimen-based documentation of prey. Technological
 advances offer new promise for these analyses.

description: The overtone and multi-mode RR Lyrae stars in the globular cluster M3 are studied using a 200-d long, $B,V$ and $I_{\mathrm C}$ time-series photometry obtained in 2012. 70\% of the 52 overtone variables observed show some kind of multi-periodicity (additional frequency at ${f_{0.61}}={f_{\mathrm {1O}}}/0.61$ frequency ratio, Blazhko effect, double/multi-mode pulsation, period doubling). A signal at 0.587 frequency ratio to the fundamental-mode frequency is detected in the double-mode star, V13, which may be identified as the second radial overtone mode. If this mode-identification is correct, than V13 is the first RR Lyrae star showing triple-mode pulsation of the first three radial modes. Either the Blazhko effect or the ${f_{0.61}}$ frequency (or both of these phenomena) appear in 7 double-mode stars. The $P_{\mathrm{1O}}/P_{\mathrm{F}}$ period ratio of RRd stars showing the Blazhko effect are anomalous. A displacement of the main frequency component at the fundamental-mode with the value of modulation frequency (or its half) is detected in three Blazhko RRd stars parallel with the appearance of the overtone-mode pulsation. The ${f_{0.61}}$ frequency appears in RRc stars that lie at the blue side of the double-mode region and in RRd stars, raising the suspicion that its occurrence may be connected to double-mode pulsation. The changes of the Blazhko and double-mode properties of the stars are also reviewed using the recent and archive photometric data.

description: The reproductive biology of the Mediterranean green crab, Carcinus aestuarii, from the Gulf of Gabes, was investigated monthly between September 2008 and August 2009. This study was motivated by the lack of information on its reproductive parameters in Tunisian waters. Thus, the sex ratio, the reproductive cycle and the size at first sexual maturity were studied in total 1399 individuals (881 females and 518 males) caught monthly from the intertidal zone and the upper sublittoral fringe. The overall samples presented a carapace width (CW) ranged between 22 and 64 mm, giving 37% of males and 63% of females. The proportions of both sexes varied depending on the size and season; the females were predominant in summer and autumn presenting 72.8 and 64.9% of samples. The size at which 50% of the population reached maturity was 34.56 and 43.93 mm CW for females and males, respectively. Seasonal changes in micro- and macroscopic properties of the gonads of both sexes showed that the reproductive activity for both sexes was greatest in autumn and winter with a major peak in October and a minor peak in January. C. aestuarii exhibited a short resting phase that occurred simultaneously in females and males from June to August.

description: We study the formation of bound states and three-component bright vector solitons in a quasi-one-dimensional spin-orbit-coupled hyperfine spin $f=1$ Bose-Einstein condensate using numerical solution and variational approximation of a mean-field model. In the antiferromagnetic domain, the solutions are time-reversal symmetric, and the component densities have multi-peak structure. In the ferromagnetic domain, the solutions violate time-reversal symmetry, and the component densities have single-peak structure. The dynamics of the system is not Galelian invariant. From an analysis of Galelian invariance, we establish that the single-peak ferromagnetic vector solitons are true solitons and can move maintaining constant component densities, whereas the antiferromagnetic solitons cannot move with constant component densities.

description: Single channel currents from Ca-activated K channels were recorded from cell-attached patches, which were then excised from 1321N1 human astrocytoma cells. Cells were depolarized with K (110 mM) so that the membrane potential was known in both patch configurations, and the Ca ionophore A23187 or ionomycin (20-100 microM) was used to equilibrate intracellular and extracellular [Ca] (0.3 or 1 microM). Measurements of intracellular [Ca] with the fluorescent Ca indicator quin2 verified that [Ca] equilibration apparently occurred in our experiments. Under these conditions, where both membrane potential and intracellular [Ca] were known, we found that the dependence of the channel percent open time on membrane potential and [Ca] was similar in both the cell- attached and excised patch configuration for several minutes after excision. Current-voltage relations were also similar, and autocorrelation functions constructed from the single channel currents revealed no obvious change in channel gating upon patch excision. These findings suggest that the results of studies that use excised membrane patches can be extrapolated to the K-depolarized cell-attached configuration, and that the relation between [Ca] and channel activity can be used to obtain a quantitative measure of [Ca] near the membrane intracellular surface.

description: In today’s trauma surgery the treatment of critical sized bone defects can cause different problems, such as stability issues and impaired healing processes. The defects often have an irregular shape and result from inflammation, tumor resection or trauma. Additive manufacturing technologies can support the filling and healing process of such critical sized bone defects. With that in mind the aim of our project is, to build a biocompatible scaffold with a spongiosa like structure using Digital-Light-Processing (DLP) technology. This printing approach has a lot of advantages compared to other printing technologies. DLP with the printer used (Lumen X, Cellink) enables to print up to a resolution of 50 micrometer allowing to build scaffolds with high and biomimetic details. Further, this technology is useful to integrate cells directly into the printing process, because of the low cytotoxicity of the applied wavelength (405nm) in combination with biocompatible BioInk´s. In our study we established a biocompatible BioInk composed of Gelatine-Methacryloyl (GelMa) a photoinitiator and a photoabsorber. We were able to show the increased biocompatibility compared to commercially available alternatives by analyzing the cellular proliferation and differentiation of mesenchymal stem cells (MSC´s) and MG63 (osteosarcoma cell line) encapsulated into the BioInk. The scaffolds printed by the established BioInk had more than four times higher DNA content after 7 days compared to the commercial GelMa BioInk alternative, indicating cellular proliferation. Confocal laser scanning imaging of the different scaffolds underlined these results. Cells in the commercial alternative BioInk stayed round in their shape while cells in self-made BioInk showed an elongated morphology after staining with Hoechst and Phalloidin TRITC and survived up to over 2 weeks. In further studies we will analyze how bioactive substances integrated into the BioInk support cell proliferation and differentiation towards an osteogenic phenotype.

description: Necturus urinary bladders stripped of serosal muscle and connective tissue were impaled through their basolateral membranes with microelectrodes in experiments that permitted rapid changes in the ion composition of the serosal solution. The transepithelial electrical properties exhibited a marked seasonal variation that could be attributed to variations in the conductance of the shunt pathway, apical membrane selectivity, and basolateral Na+ transport. In contrast, the passive electrical properties of the basolateral membrane remained constant throughout the year. The apparent transference numbers (Ti) of the basolateral membrane for K+ and Cl- were determined from the effect on the basolateral membrane equivalent electromotive force of a sudden increase in the serosal K+ concentration from 2.5 to 50 mM/liter or a decrease in the Cl- concentration from 101 to 10 mM/liter. TK and TCl were 0.71 +/- 0.05 and 0.04 +/- 0.01, respectively. The basolateral K+ conductance could be blocked by Ba2+ (0.5 mM), Cs+ (10 mM), or Rb+ (10 mM), but was unaffected by 3,4- diaminopyridine (100 microM), decamethonium (100 microM), or tetraethylammonium (10 mM). We conclude that a highly selective K+ conductance dominates the electrical properties of the basolateral membrane and that this conductance is different from those found in nerve and muscle membranes.

description: Specific oto- and rhinologic disorders such as recurrent outer ear canal infections, middle ear infections, tinnitus, and hearing loss or chronic rhinosinusitis as well as implant based pathologies such as peri-implant fibrosis or implantation related hearing loss can and should be treated by pharmacotherapy. Local pharmacotherapy to the inner ear and frontal sinus is very challenging due to physiological barriers like the blood-labyrinth barrier (BLB) or the close proximity of the frontal sinus to easily vulnerable structures like the orbital cavity and the skull base. Up to now, the results of otologic and rhinologic drug therapy are heterogeneous since the drug delivery devices are not exactly tailored to the patients needs. Individualized implants, exactly fitting to the patient’s anatomy, will help to overcome this lack of therapeutic benefit. To allow an atraumatic implantation of individualized implants into the anatomical niches and sinuses, the implant needs to be mechanically flexible. We are developing a process chain from clinical images (cone beam computed tomography), semi-automated segmentation of the region of interest using a custom-made software, 3D-printing of drug-containing material to clinical application. Implants for the outer ear canal, round window niche and frontal sinus are printed containing dexamethasone. Implants are 3D printed by a 3D-Bioplotter® Manufacturers Series (EnvisionTEC GmbH, Gladbeck, Germany) using medical-grade silicone (60A MG, BIO-83-6001, EnvisionTEC, silicone elastomer curing at 365 nm, USP Class VI). The printed specimens are tested for drug release, biocompatibility and –efficacy in vitro and in vivo. The additive manufacturing method allows the development of implants in a large volume range. The precision is acceptable for the intended applications; drug is released out of the samples and causes biological effects in vitro. Biocompatibility is given and first individual healing attempts using this novel generation of implants are performed and suggest safety and compliance.

description: The aim of the work presented here is to establish and test a prototypical, end-to-end digital and physical value chain for patient-specific implants from facial surgery (orbita implants), which are generated based on suitable AI algorithms and produced using additive manufacturing. In the first step, AI-based pre-processing of the medical image data of the orbita defect is performed. The segmentation is implemented with a Convolutional Neural Network. The segmentation process chain including the Dense U-Net was implemented in Python and training runs were conducted. For the virtual reconstruction, an approach based on Variational Autoencoders is presented along with initial trials to verify its applicability. Following imaging, an algorithm for the automated generation of implant designs is being trained. For implant manufacturing, process parameters are being developed that should lead to an optimization in AM manufacturing, especially in view of the filigree structures and component distortion. Test specimens were manufactured to validate density, microstructure and biocompatibility. A CNC blasting machine has been set up for automated post-processing to improve finished part quality. To ensure complete process traceability, a relational database structure that can import various metadata robustly was developed. Corresponding programming interfaces (APIs) were defined. To validate the complete medical workflow, it is essential to break down each process step with regard to a necessary certification. For this purpose, flow diagrams were derived, based on which a conformity assessment will be carried out in a next step.

description: We investigate the local quantum uncertainty (LQU) between a block of L qubits and one single qubit in a composite system of n qubits driven through a quantum phase transition (QPT). A first-order QPT is analytically considered through a Hamiltonian implementation of the quantum search. In the case of second-order QPTs, we consider the transverse-field Ising chain via a numerical analysis through density matrix renormalization group. For both cases, we compute the LQU for finite-sizes as a function of L and of the coupling parameter, analyzing its pronounced behavior at the QPT.

description: Obstructive sleep apnea (OSA) is a common sleeping disorder characterized by the temporal partial or complete obstruction of the upper airway during sleep. Simulating airflow and resulting deformation can help to understand the causes that lead to OSA and help to improve therapy options. In this work, the interaction between airflow and the surrounding soft tissue of an upper airway model including the nasal structures was examined with a fluid-structure interaction (FSI) simulation. The simulation was validated with experimental measurements. Therefore, an anthropomorphic 3D printed upper airway phantom of an obstructive sleep apnea patient was fabricated and used in deformation measurements to reproduce an inhalation process with a maximal flow rate of 15 l/min. The deformation was measured with a CT scanner and compared to the corresponding FSI simulation results. The comparison showed good agreement in the resulting deformation.
