Measuring the supporting slats of laser cutting machines using laser triangulation
Authors: Struckmeier Frederick , Zhao Jim , León Fernando Puente 
Published: June 2020

AbstractWhen automatically generating programs for flatbed laser cutting machines, it is advantageous to know the position of the supporting tips of the raw material. This allows the nesting layout and tool path to be adapted in an intelligent way. The problem of measuring the supporting tips of a laser cutting machine has not been considered in published literature before. We introduce possible methods first and choose a laser triangulation system. A novel setup, where none of the components is at a right angle to the measured surface, is proposed to account for the circumstances in a laser cutting machine. Its performance is investigated thoroughly with special regard to robustness and accuracy. In order to achieve very high accuracies, the setup is extrinsically calibrated on the measured object and different line extraction algorithms are tested for their effect on the measurement result. It is shown that the measurement setup is robust for different changes in the environment, such as different slat materials, bent supporting tips, and slagging. The measurement accuracy of the setup is calculated to be within ± 0.8 mm.

AbstractMarine microbial communities undergo drastic changes during the seasonal cycle in high latitude seas. Despite the dominance of microbial biomass in the oceans, comprehensive studies on the seasonal changes of microbial plankton during the complete winter period are lacking. To study the seasonal variation in abundance of the microbial community, water samples were collected weekly in the Northern Baltic Sea from October to May. During ice cover from mid-January to April, samples from the sea ice and the underlying water were taken in addition to the water column samples. Abundances of bacteria, virus-like particles, nanoflagellates, and chlorophyllaconcentrations were measured from sea ice, under-ice water, and the water column, and examined in relation to environmental conditions. All studied organisms had clear seasonal changes in abundance, and the sea-ice microbial community had an independent wintertime development compared to the water column. Bacteria were observed to have a key role in the biotic interactions in both ice and the water column, and the dormant period during the cold-water months (October–May) was limited to before ice formation. Our results provide the first insights into the temporal dynamics of bacteria and viruses during the whole cold-water season (October–May) in coastal high latitude seas, and demonstrate that changes in the environmental conditions are likely to affect bacterial dynamics and have implications on trophic interactions.

) can provide a pathway to highly efficient lead-free solar cells. Although this class of materials is known to be severely susceptible to degradation, induced among others by enhanced temperatures, humidity and illumination, an improved layer quality in view of crystal size and homogeneity is the key to diminish or even to block certain degradation channels. In this work, we present the fabrication of fully tin-based perovskites via pulsed laser deposition. The morphology is analyzed for different deposition energies and temperatures to find the optimum process window. The thin films already reveal crystalline structure at room temperature, while they are smooth and homogeneous above a critical thickness for carefully adapted deposition parameters. In contrast to the assumption that at elevated temperatures, the crystallinity is improved, and we find that the films reveal a strong organic depletion and simultaneously tin enrichment. As a measure for their suitability to be employed as photovoltaic absorbers, the band gap of the differently doped perovskites is estimated by spectroscopic ellipsometry in the range of 1.3 to 1.4 eV.

AbstractPurposeTo describe the vacuum-assisted mini-percutaneous nephrolithotomy (vmPCNL) technique performed via the 16Ch ClearPetra sheath, to evaluate its outcomes and to analyze intrarenal pressure (IRP) fluctuations during surgery.MethodsData from all consecutive vmPCNL procedures from September 2017 to October 2019 were prospectively collected. Data included patients’ and stones characteristics, intra and peri-operative items, post-operative complications and stone clearance. Patients undergoing vmPCNL from March to October 2019 were submitted to IRP measurement during surgery.ResultsA total of 122 vmPCNL procedures were performed. Median stone volume was 1.92 cm3. Median operative time was 90 min and median lithotripsy and lapaxy time was 28 min. Stone clearance rate was 71.3%. Thirty-one (25.2%) patients experienced post-operative complications, seven of which were Clavien 3. Postoperative fever occurred in nine (7.4%) patients and one (0.8%) needed a transfusion. No sepsis were observed. IRPs were measured in 22 procedures. Mean IRP was 15.3 cmH2O and median accumulative time with IRP > 40.78 cmH2O (pyelovenous backflow threshold) was 28.52 sec. Maximum IRP peaks were reached during the surgical steps when aspiration is closed (mainly pyelograms), whereas during lithotripsy and suction-mediated lapaxy, the threshold of 40.78 cmH2O was overcome in three procedures.ConclusionsvmPCNL is a safe procedure with satisfactory stone clearance rates. Mean IRP was always lower than the threshold of pyelo-venous backflow and the accumulative time with IRP over this limit was short in most of the procedures. During lithotripsy and vacuum-mediated lapaxy, IRP rarely raised over the threshold.

AbstractThe ability to generate complex hierarchical structures is a crucial component of human cognition which can be expressed in the musical domain in the form of hierarchical melodic relations. The neural underpinnings of this ability have been investigated by comparing the perception of well-formed melodies with unexpected sequences of tones. However, these contrasts do not target specifically the representation of rules generating hierarchical structure. Here, we present a novel paradigm in which identical melodic sequences are generated in four steps, according to three different rules: The Recursive rule, generating new hierarchical levels at each step; The Iterative rule, adding tones within a fixed hierarchical level without generating new levels; and a control rule that simply repeats the third step. Using fMRI, we compared brain activity across these rules when participants are imagining the fourth step after listening to the third (generation phase), and when participants listened to a fourth step (test sound phase), either well-formed or a violation. We found that, in comparison with Repetition and Iteration, imagining the fourth step using the Recursive rule activated the superior temporal gyrus (STG). During the test sound phase, we found fronto-temporo-parietal activity and hippocampal de-activation when processing violations, but no differences between rules. STG activation during the generation phase suggests that generating new hierarchical levels from previous steps might rely on retrieving appropriate melodic hierarchy schemas. Previous findings highlighting the role of hippocampus and inferior frontal gyrus may reflect processing of unexpected melodic sequences, rather than hierarchy generation per se.

Published: June 2020

AbstractAggression and psychopathy are multifaceted conditions determined interpersonal and antisocial factors. Only a few studies analyze the link between these separate factors and specific brain morphology distinctively. A voxel-based morphometry (VBM) analysis was performed on 27 violent offenders and 27 controls aiming to associate sub-features of aggressive and psychopathic behavior with specific gray matter volumes. Trait aggression was assessed using two self-report tests (Aggression Questionnaire, AQ, and Reactive–Proactive–Aggression Questionnaire, RPQ) and psychopathy with the Psychopathy Checklist-Revised (PCL-R). Total and sub-scale scores of these tests were correlated to the brain morphometry of the offenders group in separate analyses. It was found that psychopathic behavior was negatively correlated with prefrontal gray matter volume and that this result was primarily driven by the antisocial behavior sub-scale of the PCL-R. Furthermore, less gray matter in right superior frontal and left inferior parietal regions with increasing antisocial behavior could be observed. One cluster comprising the right middle and superior temporal gyrus was negatively correlated with both, reactive aggression and antisocial behavior. These results outline (1) the importance of distinctively analyzing sub-features that contribute to aggressive and psychopathic behavior, given that the negative correlation of psychopathy global scores with prefrontal volume was driven by one single facet of the PCL-R scale (antisocial behavior). Moreover, these results indicate (2) fronto-temporo-parietal network deficits in antisocial, criminal offenders, with a particular strong effect in the temporal lobe.

Summary
Purpose
The purpose of the study was to investigate whether additional reminders could enhance adherence to a 12-week program consisting of regular physical activity.

Methods
The study collective consisted of pensioners insured with the Austrian Insurance Fund for Civil or Public Servants. They were made aware of our program through the public service union. The subjects were randomized to an intervention group (group A) that received reminders and to a control group (group B) that did not receive such notifications. Adherence to physical activity was assessed by the use of diaries.

Results
Group A performed 96 min more moderate intensity regular physical activity per week than group B (group A median 269 min, r = 0–1560 min; group B median 173 min, r = 0–2700 min). The Mann–Whitney U-test showed no significant differences (p = 0.080) between the study groups.
There was no difference in muscle strengthening activity (group A: median: 2, r = 0–13 sessions; group B: median: 2, r = 0–20 sessions).

Conclusion
The major positive observation was that both the experimental and control group participants exceeded the recommended level of physical activity. Nevertheless, there were some differences concerning the minutes of physical activity performed in favor of the intervention group.
Heteromorphism of stamens in monoclinous flowers of Tinantia erecta (Jacq.) Fenzl as an example of high variability of the androecium in the Commelinaceae family
Authors: Tchórzewska D. , Marciniec R. , Deryło K. , Winiarczyk K. 
Published: June 2020

AbstractRepresentatives of the family Commelinaceae are characterised by morphologically, anatomically, or functionally diverse stamens (common presence of staminodia), which produce diverse pollen grains. The heteromorphism of stamens noted in all Commelinaceae species is a particular example of the evolutionary modification of the androecium in entomophilous plants. The morphological, anatomical, and cytological analyses of the androecium as well as the analysis of the microsporogenesis process and the formation of the male gametophyte in Tinantia erecta (a species belonging to the family Commelinaceae) have demonstrated that the morphologically diverse stamens in this species do not differ anatomically. Furthermore, the process of microsporogenesis followed by gametogenesis occurring in the stamens yields pollen grains with the same morphology, cytology, and function. Therefore, despite the large morphological diversity of the androecium, all anthers in T. erecta produce male gametophytes that are identical in every respect, which is a unique feature in species from the Commelinaceae family. Additionally, T. erecta is capable of self-pollination; hence, it can be claimed that the species uses its entire reproductive potential to produce seeds and a next generation.
Extracting safe thread schedules from incomplete model checking results
Authors: Metzler Patrick , Suri Neeraj , Weissenbacher Georg 
Published: June 2020

AbstractModel checkers frequently fail to completely verify a concurrent program, even if partial-order reduction is applied. The verification engineer is left in doubt whether the program is safe and the effort toward verifying the program is wasted. We present a technique that uses the results of such incomplete verification attempts to construct a (fair) scheduler that allows the safe execution of the partially verified concurrent program. This scheduler restricts the execution to schedules that have been proven safe (and prevents executions that were found to be erroneous). We evaluate the performance of our technique and show how it can be improved using partial-order reduction. While constraining the scheduler results in a considerable performance penalty in general, we show that in some cases our approach—somewhat surprisingly—even leads to faster executions.

Published: June 2020

ZusammenfassungEs wird ein konsistentes analytisches Berechnungsverfahren vorgestellt zur näherungsweisen Berücksichtigung von Wärmeleitungswiderständen in der Speichermasse von Regeneratoren. Die nach dem Verfahren berechneten zusätzlichen effektiven Wärmewiderstände stimmen exakt mit den nach Hausen berechneten und im VDI-Wärmeatlas angegebenen Werten überein. Das Berechnungsmodell ergibt ferner, dass für die Berechnung des Regeneratorprozesses entgegen der üblichen Praxis bei endlicher Wärmeleitfähigkeit der Speichermasse deren Wärmekapazität auf einen verkleinerten, effektiven Wert reduziert werden muss. Zur Berechnung der effektiven Speicherkapazität werden einfache Näherungsgleichungen angegeben.

AbstractAstaxanthin (Ax), the main carotenoid responsible for the distinct red flesh color in salmonids (Oncorhynchus, Salvelinus, Salmo, and Parahucho), is added to the diet of farmed fish at a substantial cost. Despite the great economical value for the salmon industry, the key molecular mechanisms involved in the regulation of muscle coloration are poorly understood. Chinook salmon (Oncorhynchus tshawytscha) represent an ideal model to study flesh coloration because they exhibit a distinct color polymorphism responsible for two color morphs, white and red flesh pigmented fish. This study was designed to identify the molecular basis for the development of red and white coloration of fish reared under the same experimental conditions and to better understand the absorption mechanism of Ax in salmonids. Pyloric caeca, liver, and muscle of both groups (n = 6 each) were selected as the most likely critical target organs to be involved respectively in the intestinal uptake, metabolism, and retention of Ax. Difference in the transcriptome profile of each tissue using next-generation sequencing technology was conducted. Ten KEGG pathways were significantly enriched for differentially expressed genes between red and white salmon pylorus tissue, while none for the transcriptome profile in the other two tissues. Differential expressed gene (DE) analyses showed that there were relatively few differences in muscle (31 DE genes,p < 0.05) and liver (43 DE genes,p < 0.05) of white and red Chinook salmon compared approximately 1125 DE genes characterized in the pylorus tissue, with several linked to Ax binding ability, absorption, and metabolism.
With all this Pseudoscience, Why so Little Pseudotechnology?
Authors: Hansson Sven Ove 
Published: June 2020

AbstractAfter a review of previous uses of the term “pseudotechnology”, a definition is proposed: “A pseudotechnology is an alleged technology that is irreparably dysfunctional for its intended purpose since it is based on construction principles that cannot be made to work”. The relationship between pseudotechnology and pseudoscience is discussed, and so is the relationship between pseudotechnology and the much weaker concept of technological malfunction. An explanation is offered of why pseudotechnology is much more seldom referred to than pseudoscience: dysfunctional technology usually reveals itself when put to use, whereas dysfunctional science tends to be more difficult to disclose.

Abstract
Purpose
Anti-human epidermal growth factor receptor 2 (HER2) therapies are associated with interstitial lung disease (ILD), also referred to as pneumonitis. In this literature review, we describe the incidence of ILD among patients with HER2-positive metastatic breast cancer (MBC) receiving anti-HER2 therapies, and we describe existing recommendations for monitoring and managing drug-induced ILD among these patients.

Methods
We searched PubMed and Embase to identify clinical trials and postmarket observational studies that investigated anti-HER2 therapies for HER2-positive MBC, reported on ILD, and were published during January 1, 2009 to July 15, 2019. Articles were screened by two researchers; data were extracted from the full-text articles.

Results
The 18 articles selected for this review assessed 9,886 patients who received trastuzumab (8 articles), lapatinib (4 articles), trastuzumab emtansine (3 articles), trastuzumab deruxtecan (2 articles), or trastuzumab duocarmazine (1 article). The overall incidence of all-grade ILD was 2.4% (n = 234), with 66.7% (n = 156) occurring as grade 1–2 events, 0.5% grade 3–4 (n = 54; incidence), and 0.2% grade 5 (n = 16; incidence). The highest ILD incidence (21.4%) was among patients receiving trastuzumab combined with everolimus and paclitaxel. Ten studies indicated that ILD events were managed via dose interruption, dose reduction, or treatment discontinuation; two studies included detailed guidelines on managing drug-induced ILD.

Conclusions
ILD is a well-described adverse drug reaction associated with several anti-HER2 drugs. Published ILD management guidelines are available for few anti-HER2 treatment regimens; however, guidance for monitoring for anti-HER2 drug-induced ILD is lacking.
Goniowash: a new surgical approach combined with cataract surgery to lower intraocular pressure in pseudoexfoliation syndrome
Authors: V. Tran Tao , Mansouri Kaweh , Mermoud Andre 
Published: June 2020

Abstract
Purpose
Pseudoexfoliation syndrome is common in elderly patients and is associated with intraocular pressure elevation. Goniowash is a novel surgical technique to remove pseudoexfoliation material from the irido-corneal angle to decrease intraocular pressure. We assessed the long-term efficacy of Goniowash on relevant parameters in patients with pseudoexfoliation syndrome, after cataract surgery.

Methods
The study enrolled 122 patients with pseudoexfoliation syndrome, who underwent routine cataract surgery combined with Goniowash. Best-corrected visual acuity, intraocular pressure and medication status were recorded in study participants during 5 years of follow-up.

Results
Data from 190 eyes (122 patients of average age 73.8 ± 7.7 years) were assessed. Mean best-corrected visual acuity increased from 0.60 to 1.0 (p < 0.001) one year after surgery and remained stable throughout the follow-up. Average intraocular pressure decreased from 26.4 ± 7.3 mmHg pre-operatively to 15.9 ± 3.0 mmHg post operatively at one year (p < 0.001), 16.1 ± 3.3 mmHg (p < 0.001) at 3 years and 16.8 ± 2.9 (p < 0.001) at 5 years. Mean number of ocular hypotensive medications decreased from 1.5 ± 0.8 pre-operatively to 0.4 ± 0.7 post-operatively (75% reduction) (p < 0.001). No unexpected and severe adverse events related to the surgical procedure were reported.

Conclusions
Goniowash combined with cataract surgery provides stable and long-lasting reduction of intraocular pressure and hypotensive medications. It is a safe procedure and may be an alternative for patients with pseudoexfoliation syndrome and elevated intraocular pressure.
Laissez-Faire Leadership and Affective Commitment: the Roles of Leader-Member Exchange and Subordinate Relational Self-concept
Authors: Robert Véronique , Vandenberghe Christian 
Published: June 2020

AbstractAlthough the detrimental effects of laissez-faire leadership are well documented, research on the underlying mechanisms and the boundary conditions associated with these effects remains scarce. Using the identity orientation framework and social exchange theory, we propose that employees with stronger relational self-concepts are more likely to be affected by laissez-faire leadership. As these employees define themselves through dyadic relationships, they may react more negatively to laissez-faire leadership by diminishing their contributions to mutual goals and reducing their affective organizational commitment. These predictions were tested within a three-wave longitudinal study through structural equations modeling analyses with full information maximum likelihood estimation on a sample of employees from multiple organizations (N = 449). As predicted, the relational self-concept was associated with a stronger negative effect of laissez-faire leadership on the contribution dimension of leader-member exchange and a stronger negative indirect effect on affective organizational commitment. The implications of these findings for our understanding of the mechanisms related to laissez-faire leadership are discussed.
