description: Attention in the literature has increasingly turned to the issue of the dependence on ensemble and boundary conditions of fluctuation-induced forces.
 We have recently investigated this problem in the one-dimensional Ising model with periodic and antiperiodic boundary conditions (Annals of Physics {\bf 459}, 169533 (2023)). Significant variations of the behavior of Casimir and Helmholtz forces was observed, depending on both ensemble and boundary conditions. Here we extend our study by considering the problem in the important case of Dirichlet (also termed free, or missing neighbors) boundary conditions. The advantage of the mathematical formulation of the problem in terms of Chebyshev polynomials is demonstrated and, in this approach, expressions for the partition functions in the canonical and the grand canonical ensembles are presented. We prove analytically that the Casimir force is attractive for all values of temperature and external ordering field, while the Helmholtz force can be both attractive and repulsive.

description: Objectives The aim of the study was to analyze the impact of concomitant coronary artery disease (CAD) assessed by the SYNTAX score (SS) and periprocedural percutaneous coronary intervention (PCI) on outcomes after transcatheter aortic valve replacement (TAVR). Background Due to controversial data regarding the effect of CAD on outcomes after TAVR, proper revascularization strategies remain a matter of debate. Methods 553 patients with severe aortic stenosis undergoing TAVR were included in this study. SS was calculated for each patient at baseline and after PCI. Primary outcome was one-year all-cause mortality. Results 60.2% of patients (N = 333) exhibited CAD with a mean SS of 10.8 ± 8.8. Of those, 120 patients (36.0%) received periprocedural PCI. In the treatment group, mean SS was decreased from 14.9 ± 9.1 to 6.3 ± 6.7. Patients with concomitant CAD suffered more frequently from myocardial infarction (MI) post TAVR compared to those without CAD (2.1% vs. 0.0%; P < 0.01). In the CAD cohort, MI rates were comparable between patients with and without PCI (2.2% vs. 2.5%; P = 0.71). Regarding SS, patients with a residual SS < 8 showed significant lower rates of one-year mortality (9.0% vs. 18.2%; P = 0.016) and MACCE (16.5% vs. 32.2%; P = 0.001). Besides left bundle brunch, predictors for an increased one-year mortality were a residual SS ≥ 8 in the CAD group (OR = 3.17; P = 0.011) and a EuroSCORE ≥ 4% in the entire study population (OR = 2.18; P = 0.017). Conclusion Our results suggest that a residual SS-guided revascularization strategy may improve prognosis after TAVR in patients with concomitant CAD. PCI aiming for a residual SS < 8 was associated with improved one-year clinical outcomes.

description: Abstract The polymorphic drug-metabolizing enzyme CYP2D6, which is responsible for the metabolism of most psychoactive compounds, is expressed not only in the liver, but also in the brain. The effects of its marked genetic polymorphism on the individual capacity to metabolize drugs are well known, but its role in metabolism of neural substrates affecting behavior personality or cognition, suggested by its CNS expression, is a long-standing unresolved issue. To verify earlier findings suggesting a potential effect on attentional processes, we collected functional imaging data, while N = 415 participants performed a simple task in which the reward for correct responses varied. CYP2D6 allelic variants predicting higher levels of enzymatic activity level were positively associated with cortical activity in occipito-parietal areas as well as in a right lateralized network known to be activated by spatial attentional tasks. Reward-related modulation of activity in cortical areas was more pronounced in poor metabolizers. In conjunction with effects on reaction times, our findings provide evidence for reduced cognitive efficiency in rapid metabolizers compared to poor metabolizers in on-task attentional processes manifested through differential recruitment of a specific neural substrate.

description: Abstract Background Retinol binding protein 1 (Rbp1) acts as an intracellular regulator of vitamin A metabolism and retinoid transport. In mice, Rbp1 deficiency decreases the capacity of hepatic stellate cells to take up all‐trans retinol and sustain retinyl ester stores. Furthermore, Rbp1 is crucial for visual capacity. Although the function of Rbp1 has been studied in the mature eye, its role during early anterior neural development has not yet been investigated in detail. Results We showed that rbp1 is expressed in the eye, anterior neural crest cells (NCCs) and prosencephalon of the South African clawed frog Xenopus laevis. Rbp1 knockdown led to defects in eye formation, including microphthalmia and disorganized retinal lamination, and to disturbed induction and differentiation of the eye field, as shown by decreased rax and pax6 expression. Furthermore, it resulted in reduced rax expression in the prosencephalon and affected cranial cartilage. Rbp1 inhibition also interfered with neural crest induction and migration, as shown by twist and slug. Moreover, it led to a significant reduction of the all‐trans retinoic acid target gene pitx2 in NCC‐derived periocular mesenchyme. The Rbp1 knockdown phenotypes were rescued by pitx2 RNA co‐injection. Conclusion Rbp1 is crucial for the development of the anterior neural tissue.

description: Zusammenfassung Frailty beschreibt einen Zustand reduzierter Belastbarkeit gegenüber Stressfaktoren, welcher u. a. Folge altersbedingter Abbauprozesse verschiedener Organsysteme ist und mit einem erhöhten Risiko für Stürze, Hospitalisationen, funktionelle Einschränkung und Mortalität assoziiert ist. Frailty tritt bei Patienten mit CKD früher und häufiger auf als in der Allgemeinbevölkerung und ist ein wichtiger und potenziell modifizierbarer Risikofaktor für eine erhöhte Sterblichkeit und Hospitalisationsrate sowie eine reduzierte Lebensqualität. Die Erkennung von Frailty bei Patienten mit CKD ermöglicht eine Identifikation von wichtigen und potenziell modifizierbaren Risikofaktoren. Eine frühzeitige nephrologische Beurteilung sowie eine interdisziplinäre Zusammenarbeit mit Geriatern, Allgemeinmedizinern, Physiotherapeuten, Ergotherapeuten und Ernährungsberatung sind essenzielle Bausteine in der Prävention und Therapie von Frailty. Zur Messung von Frailty existieren verschiedene Instrumente, wobei keines in der Erkennung von Frailty bei CKD-Patienten als überlegen identifiziert wurde. Die Auswahl des Screeninginstruments sollte daher unter Berücksichtigung der klinischen Rahmenbedingungen und der verfügbaren Ressourcen erfolgen. In diesem Artikel wird eine Strategie zur frühen Identifikation von gebrechlichen Patienten mit CKD vorgeschlagen, welche auf einer multidiemensionalen und interdisziplinären Einschätzung beruht. Wichtiger als die Methode ist jedoch die Notwendigkeit, Patienten mit Frailty zu identifizieren.

description: Background/Aims: Agitation is a burdening phenomenon that occurs in a variety of psychiatric disorders. The aim of this study was to give a first direction for agitation occurrence in depression, anxiety disorder, and borderline personality disorder (BPD) as well as in healthy controls with and without psychiatric record. Methods: Using the Hamburg-Hannover Agitation Scale (H2A), an instrument that allows for the measurement of agitation independently of the presence of a specific disorder, a patient sample (n = 158) and a healthy control group (n = 685) with (n = 94) and without (n = 591) psychiatric record were examined. The data were mainly analysed using ANOVAs and post hoc tests. Results: Patients showed significantly higher H2A agitation levels than healthy controls. Within the clinical sample, BPD patients exhibited the strongest manifestation of agitation, scoring significantly higher than the depression and the anxiety disorder sample, while these two subgroups did not significantly differ from each other. Moreover, healthy subjects with a psychiatric record experienced a significantly stronger agitation than subjects without a psychiatric record. Conclusion: Further studies are needed with larger, more balanced, and differentiated sample sizes including a wider range of clinical pictures. The results demonstrate that agitation occurs and differs in psychiatric patients as well as in healthy controls.

description: A missed cis isomeric form of a well-known trans-[CuCl2(DMSO)2]n complex has been prepared via the tetranuclear [Cu4Cl8(DMSO)8(hmta)] complex. Structurally, both complexes were found to be molecular i.e. [Cu4Cl8(DMSO)8(hmta)] consists of isolated tetracoordinated hexamethylenetetramine molecules, whereas the cis-complex consists of isolated [(DMSO)2ClCuII(μ-Cl)2CuIICl(DMSO)2] clusters. It should also be noted that the cis-configuration of DMSO molecules in [(DMSO)2ClCuII(μ-Cl)2CuIICl(DMSO)2] was directly transferred from that of [Cu4Cl8(DMSO)8(hmta)], while the trans-[CuCl2(DMSO)2]n isomer was always formed as a final stable product.

description: Social media systems are as varied as they are pervasive. They have been almost universally adopted for a broad range of purposes including work, entertainment, activism, and decision making. As a result, they have also diversified, with many distinct designs differing in content type, organization, delivery mechanism, access control, and many other dimensions. In this work, we aim to characterize and then distill a concise design space of social media systems that can help us understand similarities and differences, recognize potential consequences of design choices, and identify spaces for innovation. Our model, which we call Form-From, characterizes social media based on (1) the form of the content, either threaded or flat, and (2) from where or from whom one might receive content, ranging from spaces to networks to the commons. We derive Form-From inductively from a larger set of 62 dimensions organized into 10 categories. To demonstrate the utility of our model, we trace the history of social media systems as they traverse the Form-From space over time, and we identify common design patterns within cells of the model.

Civil occupation continued through 2nd century, but the fort may have been abandoned for part of the Hadrianic period. It was rebuilt in stone in late Hadrianic/early Antonine times and its rampart was strengthened. Another gap was followed by a short occupation in late 3rd/early 4th century, but the general lack of 4th-century material must cast doubt on the identification of this as the Alione of the Notitia.

description: Abstract Introduction Total pancreatectomy (TP) is most commonly performed to avoid postoperative pancreatic fistula (POPF) in patients with high-risk pancreas or to achieve tumor-free resection margins. As part of TP, a simultaneous splenectomy is usually performed primarily for the reason of oncologic radicality. However, the benefit of a simultaneous splenectomy remains unclear. Likewise, the technical feasibility as well as the safety of spleen and vessel preserving total pancreatectomy in pancreatic malignancies has hardly been evaluated. Thus, the aims of the study were to evaluate the feasibility as well as the results of spleen and vessel preserving total pancreatectomy (SVPTP). Material and methods Patient characteristics, technical feasibility, perioperative data, morbidity, and mortality as well as histopathological results after SVPTP, mainly for pancreatic malignancies, from patient cohorts of two European high-volume-centers for pancreatic surgery were retrospectively analyzed. Mortality was set as the primary outcome and morbidity (complications according to Clavien-Dindo) as the secondary outcome. Results A SVPTP was performed in 92 patients, predominantly with pancreatic adenocarcinoma (78.3%). In all cases, the splenic vessels could be preserved. In 59 patients, the decision to total pancreatectomy was made intraoperatively. Among these, the most common reason for total pancreatectomy was risk of POPF (78%). The 30-day mortality was 2.2%. Major complications (≥ IIIb according to Clavien-Dindo) occurred in 18.5% within 30 postoperative days. There were no complications directly related to the spleen and vascular preservation procedure. A tumor-negative resection margin was achieved in 71.8%. Conclusion We could demonstrate the technical feasibility and safety of SVPTP even in patients mainly with pancreatic malignancies. In addition to potential immunologic and oncologic advantages, we believe a major benefit of this procedure is preservation of gastric venous outflow. We consider SVPTP to be indicated in patients at high risk for POPF, in patients with multilocular IPMN, and in cases for extended intrapancreatic cancers. © In Copyright http://rightsstatements.org/vocab/InC/1.0/

description: The aim of this study is to present a new morphodynamic map (1:10,000 scale) of a wave-dominated sector of a Mediterranean ria-type coast (NE Sardinia, Italy). The area has been studied since 1995 with respect to its geomorphological and sedimentological processes. Our map is produced using topographic-bathymetric, textural and compositional data collected during different surveys conducted from 1995 to 2014. The Main Map shows forms, processes and deposits of the coastal belt, as well as the main geological outcrops, structural elements and the areal distribution of seagrass, mainly Posidonia oceanica (L.) Delile and Caulerpa prolifera (Forsskaal) Lamouroux. The map is useful for beach management purposes. It is noteworthy that the role of P. oceanica in the littoral area is twofold: (1) acts as a barrier to siliciclastic material from the backshore; and (2) a producer of biogenic/bioclastic sediment. Based on side-scan sonar images, the P. oceanica meadow appears to be threatened by direct mechanical damage caused by boat anchoring and mooring activities. The human impact on dune habitats has also been recognized and is related to pedestrian and vehicular transit, boat storage and infrastructure for bathing.

description: Abstract Purpose To clarify the relative influence of age, sex, disc height loss and T1 slope on upper (Occiput-C2) and lower cervical lordosis (C2–C7). Methods Standing lateral cervical radiographs of 865 adult subjects were evaluated. The presence and severity of disc height loss from C2/C3 to C6/C7 (a total of 4325 discs) were assessed using a validated grading system. The total disc height loss score for each subject was calculated as the sum of the score of each disc space. Sagittal radiographic parameters included: occipital slope, occiput-C2 (Oc-C2) lordosis, C2–C7 lordosis and T1 slope. Multivariable regression analyses were performed to examine the relative influence of the multiple factors on upper and lower cervical lordosis. Results This study included 360 males and 505 females, with a mean age of 40.2 ± 16.0 years (range, 20–95 years). Linear multivariate regression analyses showed that greater age, male sex, greater T1 slope were each found to be significantly and independently associated with greater C2–C7 lordosis, whereas total disc height loss score was negatively associated with C2–C7 lordosis. T1 slope had the most independent influence on C2–C7 lordosis among these factors. Age, sex and disc height loss were not independently associated with Oc-C2 lordosis. Conclusions Results from our large-scale radiologic analysis may enhance the understanding of the factors that affect cervical lordosis, indicating that age, sex, disc height loss and T1 slope were each independently associated with C2–C7 lordosis. However, age, sex and disc height loss were not independently associated with upper cervical lordosis.

description: Subwavelength gratings play a fundamental and pivotal role in numerous science and applications for wave manipulation, exhibiting distinctive features such as filtering, phase manipulation, and anti-reflection. However, conventional fabrication methods for ultrasmall periodic structures are constrained by the fundamental optical diffraction limit, making it challenging to produce subwavelength gratings for optics. Here, we demonstrate a novel technique to build a reconfigurable subwavelength photorefractive grating (SPG) in a thin-film lithium niobate on the platform of an optical microcavity. Such SPGs are optically induced through the photorefractive effect and the subwavelength features originate from the spatial phase modulations of the pump's standing wave. The resulting SPGs lead to the mode splitting of two counter-propagating modes inside the microcavity, exhibiting an Electromagnetically Induced Transparency (EIT)-like transmission spectrum. Moreover, the unique subwavelength characteristic of SPGs enables first-order quasi-phase-matching for backward second-harmonic generation, a long-standing problem in nonlinear optics. Also, free-space-to-chip vertical nonlinear frequency conversion can be achieved in a similar manner. These results provide a flexible approach towards fabricating subwavelength gratings, which holds significant potential in various applications such as nonlinear frequency conversion, optical communication, sensing, and quantum technologies.

description: Purpose Perioperative cognitive dysfunction can be observed in all age groups of patients. Sometimes, this is more stressful to the patient than the actual surgical wound. Enhanced recovery after surgery pathways screen for patients at risk and lead to early post-surgical intervention. To prevent cognitive dysfunction, a prehabilitation approach might be useful. Methods This systematic literature review provides an overview on the current knowledge on prehabilitation for cognitive dysfunction for gynaecological patients by searching the National Library of Medicine (PubMed) in February 2020 to identify publications regarding presurgical cognitive training with three different search terms. Results 501 articles were identified and after screening for eligibility five were left for further analysis. Generally, cognitive function is split into several cognitive aspects like anxiety or memory, speed, attention, flexibility or problem-solving functions. Each of these aspects can/need to be trained to show an improvement after general anaesthesia. Training possibilities range from relaxation methods via music, one-on-one personal training sessions to electronically supported training units. Conclusion Prehabilitation of the cognitive function can be split in different cognitive domains. Each of these domains seem to be influenced by training. The training itself can be based on applications or known relaxation methods or even old-fashioned board games. The evidence is, however, still low and there is a need for further studies.

description: The development of polymeric coatings for brittle substrates such as ceramics or glass is an important technological goal, the aim of which is to provide protection or enhance the mechanical properties of the substrate. In this work we propose a novel one-step approach, evaporation-driven self-assembly of polymers, to coat Al2O3 substrates with a thin nanocomposite coating. The films consist of polyvinyl butyrate polymer and either multi-walled carbon or tungsten disulfide nanotubes, which are found to improve both the strength and toughness of the brittle alumina substrates via crack bridging and crack propagation inhibition mechanisms.

description: Ultra-wideband positioning systems intended for indoor applications often work in non-line of sight conditions, which result in insufficient precision and accuracy of derived localizations. One of the possible solutions is the implementation of cooperative positioning techniques. The following paper describes a cooperative ultra-wideband positioning system which calculates tag position from TDOA and distance between tags measurements. In the paper positioning system architecture is described and an exemplary transmission scheme for cooperative systems is presented. Considered localization system utilizes an Extended Kalman Filter based algorithm. The algorithm was investigated with simulations and experiments. Conducted experiment consisted in fusing results gathered from typical TDOA positioning system infrastructure and ranging results obtained with ultra-wideband radio modules. The research has shown that the use presented cooperative algorithm increases positioning precision.

description: The first Quantum Key Distribution (QKD) networks are currently being deployed, but the implementation cost is still prohibitive for most researchers. As such, there is a need for realistic QKD network simulators. The \textit{QKDNetSim} module for the network simulator NS-3 focuses on the representation of packets and the management of key material in a QKD network at the application layer. Although QKDNetSim's representation of a QKD network is insightful, some its components lack the depth that would allow the simulator to faithfully represent the behaviour of a real quantum network. In this work, we analyse QKDNetSim's architecture to identify its limitations, and we present an enhanced version of QKDNetSim in which some of its components have been modified to provide a more realistic simulation environment.

description: Abstract Background Interprofessional education has emerged as a key concept in education of health professionals over the last 20 years. Positive effects of interprofessional education have been shown, but it has proved to be more time-consuming than traditional teaching methods. We therefore developed a 30-minute interprofessional learning activity, using peer-teaching methods. We were interested in effects on and ways of interprofessional learning, including conditions and resources that make it successful despite limited time. Methods Speed InterprofESsional Peer Teaching PaediAtric (SIESTA) was developed in the context of an interprofessional training ward. 20 paediatric nursing trainees and 20 medical students were enrolled in the study. Two students from each profession participated in a total of four SIESTA sessions each, supervised by registered paediatric nurses and paediatricians. We used a mixed-methods approach of quantitative and qualitative data (questionnaires, semi-guided focus group interviews) to evaluate self-perceived interprofessional competencies, interprofessional learning gains and ways of interprofessional learning. Results Questionnaires were obtained from all participants (n = 40) and n = 26 took part in the group interviews. Participants from both professions reported an increase in self-perceived understanding of interprofessional roles and tasks. Communication and cooperation emerged as important aspects. The workplace-based nature of SIESTA promoted interprofessional learning, while peer teaching fostered a safe learning environment. Regarding time constraints participants suggested thorough preparation and structuring by facilitators as a solution. Conclusions Our short interprofessional peer teaching activity showed promising results. Participants reported enhanced interprofessional competencies and provided suggestions for successful learning in limited time. Further studies should include an objective assessment of the interprofessional learning progress. The SIESTA concept can be easily adapted to other medical fields, providing interprofessional learning opportunities for many more health care professionals to come.

description: Behavioural courtship display and size of males are two attributes often used by females to select a mating partner. According to sexual selection, such traits are of importance, because a bigger size male or males displaying a better courtship could enhance the possibility of females to transmit her genes to the following generations via her offspring. In Hymenoptera such as in solitary bees, it is known that females can assess male quality and add this information in the process of mating choice. In the current study, I describe aspects of pre-copulatory mating behaviour of males, male quality assessment and female choice in the large-headed resin bee Heriades truncorum (Hymenoptera: Megachilidae: Osminii). Males of Heriades truncorum perform thoracic vibration, fan their wings and lift upwards female’s abdomen to copulate. Couples engage in sideways rocking motion movement like a dance. Female selection of a partner was also found to be density dependent. In a pair situation (one female for one male), female copulate equally with males of all sizes and male mating effort enhanced the chance of successful copulation. In an environment with mating choices (one female for two males of different sizes), successful copulation was significantly more frequent for bigger size males. Female response to male mounting took place independently of the number of mating partners in the arena and did not impair mating. Additionally, size had no effect on male-male competition. Both results suggest mating success in Heriades truncorum rely on a female choice mechanism.

description: Aerial photography and fieldwork undertaken in 1997 suggests that during the early medieval period, natural pools within the Moss were used for hemp retting. It appears that the water levels within the pools were controlled by the construction of narrow ditches and possibly simple sluice systems. One of the pools appears to have been used for retting in the seventh century AD, it dried out during the late-twelfth to mid-thirteenth centuries. Disruption to the pool hydrology resulted in the colonisation of the edges of both pool and ditch by Calluna vulgaris (heather). (see also 2002/362)

description: Tropical ecosystems are currently degrading at unprecedented speed, mostly due to rapid human population growth. This affects the associated biodiversity, which frequently results in damage to or loss of ecosystem functions. Due to high species richness and ecological diversity, bats are essential ecosystem elements. Our objective was to determine effects of land-use categories on species abundance, richness and diversity of the guild of fruit bats (Chiroptera: Pteropodidae) on Mt. Kilimanjaro, a biodiversity hotspot in Tanzania. We surveyed five habitat types, including two natural habitats lower montane forest and savanna, and three disturbed habitats, coffee plantations, Chagga homegardens, and maize fields. We captured 629 frugivorous bats and (1) compared diversity and species abundance among the habitat types and (2) assessed factors driving the differences in guild structure along an elevational gradient. Species accumulation curves were asymptotic for all habitats, suggesting an adequate sampling effort. Non-metric multidimensional scaling analysis indicated strong differentiation of fruit bat guilds among habitats. Highest species richness was recorded in lower montane forest and Chagga homegardens, which therefore represent habitats of high value for these bats. Nevertheless, even in the intensively used coffee plantations and maize fields we found a high abundance of bats from most species despite a low abundance of food resources. Our results suggest that bats do not perceive moderately sized plantations as a hostile matrix, but rather use them as flyways between fragments and patches of secondary vegetation. Further, we suggest that within plantations, trees like Ficus spp. increase bat activity.

description: Reports that a number of features, probably associated with the urban expansion of the thirteenth century, were sealed by a fourteenth to fifteenth century horizon. The posts of medieval timber buildings were identified and there is evidence for refurbishment and perhaps rebuilding of some timber structures on the site. Building in stone was obviously a post-medieval development in Penrith, perhaps reflecting the enhanced prosperity of the town from the later seventeenth century onwards. Finds dating from the earlier post-medieval period were limited, but included glass, a small sample of clay tobacco pipes and 454 sherds of pottery. A further 342 sherds of medieval pottery were found.

description: Luminescent complexes with general formula [(C^N)2Ir(N^N)]OCOCH3, where C^N = 2-phenylpyridine (ppy) and N^N = 2,2ʹ-bipyridine (bpy), self-assemble into ordered ‘soft’ viscous mesophases of chromonic type. By changing the ancillary ligand with 1,10-phenanthroline (phen), a new mesomorphic complex was obtained. The self-assembly into ordered liquid crystalline phases of chromonic type in water was investigated by comprehensive rheological and photophysical studies. By changing the ancillary ligand bpy with phen, assembly into smaller, more symetric aggregates is favoured, resulting in lower viscosity and more dynamic mesophase.

description: Objective: To evaluate the efficacies of different chemotherapy regimens in different risk sub-groups for the prevention of bladder recurrence after radical nephroureterectomy (RNU). Materials and Methods: Between 2004 and 2012, we recruited 685 patients who underwent RNU for upper tract urothelial carcinoma at 4 Chinese institutions. We assessed whether the type of intravesical chemotherapy regimen affected the bladder recurrence rate in patients with different risk levels after RNU. Results: For all patients, the bladder recurrence rate was lower with intravesical chemotherapy than without, but no significant differences were found between the 2 intravesical chemotherapy regimens (single dose or relatively long-term therapy). We used multivariate analysis to define the risk factors for bladder recurrence and stratified patients into low-, intermediate-, and high-risk sub-groups accordingly. The bladder recurrence rate in the low-risk patients was not significantly different between patients with or without intravesical chemotherapy. However, in the intermediate-risk and high-risk patients, the rate was greater in patients without intravesical chemotherapy than in patients with. Furthermore, the rate was not significantly different between the 2 intravesical chemotherapy regimens in the intermediate-risk patients, while the efficacy of the relatively long-term regimen in high-risk patients remains unclear. Conclusions: Our study showed that an individualized strategy based on patient risk stratification is needed.
