SIP: Berufsdermatologische Präventions-Seminare
Authors: Weisshaar E. , Weseloh C. 
Published: July 2019

ZusammenfassungBerufliche Hautkrankheiten zählen zu den häufigsten Berufskrankheiten, insbesondere in den Industrieländern. Das Gesundheitswesen, die Metallbearbeitung, das Friseurhandwerk, das Baugewerbe und die Lebensmittelindustrie sind dabei besonders betroffen. In diesen Berufen ist die Haut der Beschäftigten oft Wasser, arbeitsspezifischen Reizstoffen und Allergenen ausgesetzt und es besteht ein hohes Risiko, ein Kontaktekzem, am häufigsten an den Händen, zu entwickeln. Die Folgen auf individueller und gesellschaftlicher Ebene sind enorm. Berufliche Hauterkrankungen verursachen hohe Kosten. Fehlzeiten und mangelnde Produktivität belasten insbesondere kleine und mittlere Betriebe. Der Prävention berufsbedingter Hauterkrankungen kommt daher seit Jahren eine wichtige Bedeutung zu. Auf ambulanter Versorgungsebene spielt die sekundäre Individualprävention (SIP) eine wesentliche Rolle. Sie beinhaltet ein ambulantes dermatologisches Heilverfahren sowie das Angebot von interdisziplinären Hautschutzseminaren. Frühzeitig eingeleitete Präventions- und Therapiemaßnahmen können der Manifestation einer Berufserkrankung nach BK 5101 entgegenwirken und Kosten sparen.
Correlation between Vitalism and Genetics According to the Paradigm of Complexity
Authors: Teixeira Marcus Zulian 
Published: July 2019

Background In homeopathic philosophy, vital force is a non-material substrate that is responsible for maintaining the body's sensations and functions and where homeopathic medicines act. In genetics, the body's vital functions are controlled by biochemical information, which is contained in the cell genome and consists of a protein encoding portion (exome) and another that regulates this encoding scheme (epigenome). Both the philosophical vital force and the genome present properties of complex and dynamic self-organisation systems.
Aims This study aimed to explore and develop a philosophical-scientific correlation between vitalism and genetics according to the complexity paradigm.
Results Vital principle and genome present inseparable composition among distinct existing components that influence one another and form a network of connections that create complex and dynamic self-organisation behaviour. Described in both models, ‘vortex’ indicates the existence of a force coming from within the system that is externalised as an emergent, information-transmitting phenomenon. Supporting this correlation, some experimental studies show that homeopathic medicines act on the genome by modulating gene expression.
Conclusions In line with the similarity of existing characteristics and properties, the genome may be considered as hypothetical biological substrate of organic vital force.

Published: July 2019

AbstractMetachromatic leukodystrophy (MLD) is a rare sphingolipid storage disorder caused by arylsulfatase A (ARSA) deficiency, resulting in central and peripheral demyelination. However, an uncommon form of MLD caused by saposin B deficiency is also described (around 10 mutations reported till date). MLD is a systemic disorder affecting the central and peripheral nervous system, gall bladder, and kidneys. Acute flaccid paralysis as the initial clinical presentation is previously known in ARSA-deficient MLD. Hereby, we report a child with acute flaccid paralysis with brain magnetic resonance imaging showing nonspecific periventricular leukodystrophy. He had progressive cognitive decline with gall bladder polyposis. ARSA levels were within normal limits. Leukodystrophy gene panel revealed a homozygous pathogenic deletion (Lys227del variant) in prosaposin (PSAP) gene. Hence, a final diagnosis of saposin B–deficient MLD was established. The index case highlights the importance of clinical and electrophysiological clues in the diagnosis of such atypical presentations of MLD.

Published: July 2019

Abstract
Background Chronic venous insufficiency (CVI) manifests as unilateral or bilateral lower-limb venous hypertension causing pain, swelling, edema, and skin changes, among other symptoms. CVI affects patients’ socioeconomic status, is particularly seen in the young, and, in its severe manifestation, may have a debilitating effect on patients’ quality of life (QoL). The authors wanted to evaluate change in pain and QoL among rural patients after endovenous laser ablation (EVLA) treatment in a pilot study.
Methods Twenty patients having CVI who opted for 1,470-nm EVLA treatment were enrolled at the Interventional Radiology department between July 2018 and September 2018. The authors evaluated pain using the visual analog scale (VAS) before and after EVLA procedure (standard protocol) of the affected vein. They also assessed QoL using the Aberdeen Varicose Vein Questionnaire before and 6 weeks after EVLA.
Results The authors observed significant reduction in pain postprocedure versus preprocedure. Majority of the patients had improvement in itching and stasis dermatitis after the procedure. Rash and skin ulcers remained uncommon before and after EVLA. Also, after EVLA, fewer patients than before reported that the appearance of their diseased veins caused them concern (35 vs. 65% before EVLA), influenced their choice of clothing (45 vs. 80%), interfered with their work (40 vs. 90%), and interfered with their leisure activities (30 vs. 80%).
Conclusion EVLA 1470nm procedure may help patients with CVI attain improved QoL and significant pain reduction.
Use of the Magellan Robotic System for Conventional Transarterial Chemoembolization (cTACE): A 6-Patient Case Series Showing Safety and Technical Success
Authors: Clements Warren , Scicchitano Madeleine , Koukounaras Jim , Joseph Tim , Goh Gerard S. 
Published: July 2019

AbstractRobotic endovascular technology is an emerging concept, and is being developed to allow more precise navigation of anatomy in challenging endovascular cases. The Magellan Endovascular System allows either direct or remote steerability of a 2-point articulating robotic platform with the ability to place a conventional microcatheter through the catheter tip. Such flexibility may help to reach an otherwise difficult anatomic location, especially in variant anatomy. To date, this platform has been shown to be technically successful in a small number of different settings. This case series shows another potential platform for such technology and explores the technical use and overall safety in conventional transarterial chemoembolization (cTACE). The study retrospectively assessed 6 patients undergoing selective cTACE. Treatments were performed in a single center by two experienced interventional radiologists. Fluoroscopy time, radiation dose, anatomic target, and adverse events were logged. In spite of a longer than expected average fluoroscopy time, which can be expected for a first-generation technology, the average radiation dose was comparable to literature and technical success was able to be shown in all 6 patients with no adverse events. This technology has wide scope for future use and once overcoming a learning curve, may allow us to avoid repeat procedure attempts thus reducing fluoroscopy time and leading to earlier successful treatment. Providing a platform of interest and usability in the interventional radiology world may also lead to further development of smaller, cheaper, and more widely-accessible devices.
Conformational switching of chiral colloidal rafts regulates raft–raft attractions and repulsions

Published: July 2019

Significance
We describe hierarchical assemblages of colloidal rods that mimic some of the complexity and reconfigurability of biological structures. We show that chiral rod-like inclusions dissolved in an achiral colloidal membrane assemble into rafts, which are adaptable finite-sized liquid droplets that exhibit 2 distinct chiral states of opposite handedness. Interconverting between these 2 states switches the membrane-mediated raft interactions between long-ranged repulsions and attractions. Rafts with switchable interactions assemble into analogs of electrostatic complexation observed in charged particulate matter. Our results demonstrate a robust pathway for self-assembly of reconfigurable colloidal superstructures that does not depend on tuning the shape and interactions of the elemental units, but rather on the complexity of the emergent membrane-mediated interactions.
Random coefficient autoregressive processes describe Brownian yet non-Gaussian diffusion in heterogeneous systems
Authors: Ślęzak Jakub , Burnecki Krzysztof , Metzler Ralf 
Published: July 2019

Abstract
Many studies on biological and soft matter systems report the joint presence of a linear mean-squared displacement and a non-Gaussian probability density exhibiting, for instance, exponential or stretched-Gaussian tails. This phenomenon is ascribed to the heterogeneity of the medium and is captured by random parameter models such as ‘superstatistics’ or ‘diffusing diffusivity’. Independently, scientists working in the area of time series analysis and statistics have studied a class of discrete-time processes with similar properties, namely, random coefficient autoregressive models. In this work we try to reconcile these two approaches and thus provide a bridge between physical stochastic processes and autoregressive models. We start from the basic Langevin equation of motion with time-varying damping or diffusion coefficients and establish the link to random coefficient autoregressive processes. By exploring that link we gain access to efficient statistical methods which can help to identify data exhibiting Brownian yet non-Gaussian diffusion.
Handling leakage with subsystem codes
Authors: Brown Natalie C , Newman Michael , Brown Kenneth R 
Published: July 2019

Abstract
Leakage is a particularly damaging error that occurs when a qubit state falls out of its two-level computational subspace. Compared to independent depolarizing noise, leaked qubits may produce many more configurations of harmful correlated errors during error-correction. In this work, we investigate different local codes in the low-error regime of a leakage gate error model. When restricting to bare-ancilla extraction, we observe that subsystem codes are good candidates for handling leakage, as their locality can limit damaging correlated errors. As a case study, we compare subspace surface codes to the subsystem surface codes introduced by Bravyi et al. In contrast to depolarizing noise, subsystem surface codes outperform same-distance subspace surface codes below error rates as high as ⪅ 7.5 × 10−4 while offering better per-qubit distance protection. Furthermore, we show that at low to intermediate distances, Bacon–Shor codes offer better per-qubit error protection against leakage in an ion-trap motivated error model below error rates as high as ⪅ 1.2 × 10−3. For restricted leakage models, this advantage can be extended to higher distances by relaxing to unverified two-qubit cat state extraction in the surface code. These results highlight an intrinsic benefit of subsystem code locality to error-corrective performance.

output of 3.1 W, and low intensity noise in audio frequency region. To suppress the intensity noise of the high power 532 nm laser, a laser frequency locking system and a feedback loop based on a Mach–Zehnder interferometer were designed and used. The influences of the frequency stabilization and the crucial parameters of the MZI, such as the power splitting ratio of the beam splitters and the locking state of the MZI, on the intensity noise of the 532 nm laser were investigated in detail. After the experimental optimizations, the laser intensity noise in the frequency region from 0.4 kHz to 10 kHz was significantly suppressed.
Shades of dark uncertainty and consensus value for the Newtonian constant of gravitation
Authors: Merkatas Christos , Toman Blaza , Possolo Antonio , Schlamminger Stephan 
Published: July 2019

Abstract
The Newtonian constant of gravitation, G, stands out in the landscape of the most common fundamental constants owing to its surprisingly large relative uncertainty, which is attributable mostly to the dispersion of the values measured for it by different methods and in different experiments, each of which may have rather small relative uncertainty.
This study focuses on a set of measurements of G comprising results published very recently as well as older results, some of which have been corrected since the original publication. This set is inconsistent, in the sense that the dispersion of the measured values is significantly larger than what their reported uncertainties suggest that it should be. Furthermore, there is a loosely defined group of measured values that lie fairly close to a consensus value that may reasonably be derived from all the measurement results, and then there are one or more groups with measured values farther away from the consensus value, some appreciably higher, others lower.
This same general pattern is often observed in many other interlaboratory studies and meta-analyses. In the conventional treatments of such data, the mutual inconsistency is addressed by inflating the reported uncertainties, either multiplicatively, or by the addition of ‘random effects’, both reflecting the presence of dark uncertainty. The former approach is often used by CODATA and by the Particle Data Group, and the latter is common in medical meta-analysis and in metrology. However, both achieve consistency ignoring how the measured values are arranged relative to the consensus value, and measured values close to the consensus value often tend to be penalized excessively, by such ‘extra’ uncertainty.
We propose a new procedure for consensus building that models the results using latent clusters with different shades of dark uncertainty, which assigns a customized amount of dark uncertainty to each measured value, as a mixture of those shades, and does so taking into account both the placement of the measured values relative to the consensus value, and the reported uncertainties. We demonstrate this procedure by deriving a new estimate for G, as a consensus value

Published: July 2019

Abstract
Spent fuel pool uses water to temporarily cool spent nuclear fuels before final disposal. The Malaysian Nuclear Agency is recently working on its spent fuel pool facility to store irradiated TRIGA fuel rods. These irradiated fuels still contain significant amount of fissile material which are capable to induce criticality in the fuel storage facility. This study is therefore performed to investigate the safety criticality analysis for the proposed fuel storage rack design of 5x5 arrays. MCNP5 code was used to model the 5x5 array of fuel storage rack in order to determine the optimal fuel pitch distance. The analysis was based on the standard UZrH1.6 TRIGA fuel cladded with stainless steel used in PUSPATI TRIGA Reactor, which is 19.9% enriched 235U and 20% weight of Uranium. By varying the pitch distance between 4 cm to 14 cm with no neutron absorber included, the optimum fuel rack design was determined where sub-criticality condition can be maintained.
An overview of the development of a multigroup Monte Carlo code for TRIGA reactors
Authors: Omar M R , Karim J A , Yoon T L 
Published: July 2019

Abstract
This paper discusses the overview of the development of TRIMON, a next-generation core management code for TRIGA reactors. The newly developed code employs Monte Carlo method which uses diffusion theory type homogenized neutron cross section data, thus, speeding up the stochastic simulation via simplification of a complex core geometry. It has the capability of running three-dimensional core simulation up to 16 neutron energy groups. In general, the group neutron cross sections are pre-processed and homogenized via the Effective Diffusion Homogenization (EDH) method. The important features of TRIMON include core eigenvalue calculation, fuel burnup management, three-dimensional power and neutron flux distribution prediction. In this paper, the numerical results obtained using TRIMON were compared with the actual measured operational data. The performance comparison was also made between TRIMON and MCNP.
A review on multilayer radiation shielding
Authors: Arif Sazali Muhammad , Alang Md Rashid Nahrul Khair , Hamzah Khaidzir 
Published: July 2019

Abstract
Radiation shielding is a body of material that is placed between a radiation source and an object to be protected with the aim of reducing the intensity of radiation at the object’s location. It can be made from various materials. These materials can be stacked into a multilayer shield or they can be mixed into a composite shield. The main objective of the present study is to review the list of multilayer shield combinations that have been studied and to highlight the findings on material arrangement and consequent buildup factor. The scope of the study is limited to the results of the performed studies. It was observed that there was no clear method on arranging the layer. Buildup factor was also found to be complicated in multilayer shields. Future studies may focus on new multilayer shielding design with unlisted materials, complementary buildup calculations, and applications of metaheuristics in shielding optimization.

Abstract
Gamma and neutron irradiation effect on sand and activated carbon were studied in this paper intensively and, were found from various studies to have strong correlation between neutron fluence or gamma energy on physical and mechanical damage of materials. Sand and activated carbon were irradiated with neutron at Reactor TRIGA PUSPATI (RTP) and gamma at Sinagamma Malaysia Nuclear Agency (Nuklear Malaysia). Morphological analysis was carried out on the irradiated elements using the SEM, XRD and SAXS which showed changes on the microstructure of irradiated samples. Irradiation of activated carbon showed increase in the numbers of pores while change of textural profile of the surface take place at gamma irradiated sand. XRD pattern graph did not indicate any changes, however the specific surface area for both irradiation materials decreased.

Abstract
The aim of this study was to evaluate the performance of corn starch-bonded Rhizophora spp. particleboards as phantom for SPECT/CT including the image contrast, source dimension ratio and recovery coefficient values. Phantom set made of the Rhizophora spp. particleboards was constructed according to the Jaszczak phantom commonly used in SPECT/CT with external dimension of 22 and 18 cm diameter and length respectively. Cylindrical vials with different diameter sizes filled with 99mTc unsealed source were inserted in drilled holes of the constructed particleboards phantom. The particleboards phantom was scanned by using SPECT/CT scanning mode and the SPECT images were reconstructed using clinical protocol. The results showed that the contrast value, source dimension ratio and recovery coefficient of Rhizophora spp. particleboards in good agreement with Jaszczak phantom. The overall results showed an excellent agreement of performance between corn starch-bonded Rhizophora spp. particleboards to the Jaszczak (water) as standard phantom material. The overall results indicated that the corn starch-bonded Rhizophora spp. can be highly recommended to be used as tissue-equivalent phantom material for Quality Assurance and dosimetry works in SPECT/CT imaging.
