Abstract
Background and Aims External pancreatic fistula occurring in the setting of disconnected pancreatic duct syndrome leads to significant morbidity, often requiring surgery. The aim of this study is to report a new technique of endoscopic ultrasound (EUS)-guided rendezvous and tractogastrostomy in patients with disconnected pancreatic duct syndrome and external pancreatic fistula.
Methods This study is retrospective analysis of the data of the patients with external pancreatic fistula who had undergone EUS-guided rendezvous and tractogastrostomy. Internalization of pancreatic secretions was performed by placing a stent between tract and the stomach. Technical success was defined as placement of stent between the tract and the stomach. Clinical success was defined as removal of external catheter and absence of peripancreatic fluid collection, ascites or external fistula at 3 months after the tractogastrostomy.
Results Four patients, all male, with median age of 33.5 years (range: 29–45), underwent EUS-guided tractogastrostomy. Technical and clinical success was 100%, without any procedure related complication. External catheter could be removed in all the patients. During the median follow-up of 10.5 months (range: 8–12), two patients had stent migration and peripancreatic fluid collection, which were managed by EUS-guided internal drainage.
Conclusions EUS-guided rendezvous and tractogastrostomy are a safe and effective technique for the treatment of external pancreatic fistula.
Negative emotions and consumer behavioural intention to adopt emerging e-banking technology
Authors: Abikari Masoome , Öhman Peter , Yazdanfar Darush 
Published: August 2022

AbstractSuccessful implementation of e-banking technology depends on how consumers perceive the technology and how likely they are to adopt it. Although several studies have analysed the impact of some specific negative emotions, few studies examine a broad range of consumers’ negative emotions (i.e. both deterrence and loss emotions) arising from appraisals of e-banking technology. This study investigates the possible relationships between deterrence and loss emotions, and consumers’ behavioural intention to adopt emerging e-banking technology. Based on the unified theory of acceptance and use of technology, partial least squares structural equation modelling was used to analyse a conceptual model and related hypotheses. The empirical evidence draws attention to the relationship between loss emotions and consumers’ behavioural intention to adopt emerging e-banking technology through effort expectancy and performance expectancy, respectively.
Torturing environments and multiple injuries in Mexican migration detention
Authors: Manek Julia , Galán-Santamarina Andrea , Pérez-Sales Pau 
Published: August 2022

AbstractMexico’s role in the US-Central American migration regime is threefold: not only is it a country of origin, and a transit country, but also increasingly becoming a receiving country for migrants who flee from violence, insecurity and poverty. The Mexican state responds with detention enforcement. Clinical research usually puts emphasise on the negative impact of detention enforcement on the detainees‘ mental health. Yet, it often disregards the spatial configurations of detention centres and their socio-political context. This study aims to fill this gap by analysing how such factors create harmful environments that affect both the detainees‘ mental health and their social life in Mexico’s migration detention centres. The study’s mixed method approach builds on semi-structured interviews with a sample ofN = 56 migrants of diverse nationalities and varying socioeconomic status of whom 22 were still detained while 34 had been released. The interviews include the Torturing Environment Scale (TES), a novel instrument for the analysis of detention environments, as well as clinical psychological measures of emotional distress. Additionaln = 10 in-depth interviews with human rights advocates to explore the interconnections between the detention environments, their impact on mental health, and Mexican migration politics. Facultative counter-mappings of the detention centres complement the interviews. Without exception, all interviews of detainees underline that the manipulation of detention conditions creates torturing environments that cause harm to basic physiological and psychological needs. A comparison between detained vs. released interviewees revealed lasting feelings of fear and shame. The study emphasises that immigration detention immobilises migrants in a necropolitical limbo, which destroys hope as much as human integrity. It indicates that detention is part of deterrence politics, which perpetuates harm and inequality through detention and deportation. Highlighting structural human rights violations, the findings stress the need to review current migration policies.
Constructivism in Kant’s theoretical philosphy
Authors: Pereira Roberto Horácio de Sá 
Published: August 2022

AbstractWe set forth what one may call a “constitutional reading” in opposition to the traditional widespread “constructivist reading” of the object of cognition. In the light of the so-called one-object view reading of Transcendental idealism, the object of cognition is nothing but the object that exists in itself insofar as it appears to our cognitive apparatus. The objectexists mind-independently, while our cognitionof the same object must be mind-independent. The constructivist reading mistakes the epistemological problemof how we come to cognize mind-dependently that what we represent(“the constitutional view”) are mind-independent objects with the Berkelian ontological problem ofhow we construct objects out of an undifferentiated, unstructured manifold(the constructivist view) My diagnosis is as follows. The first reason is the traditional “two-worlds view” reading of Kant’s idealism: if we take whatexists in itselfandthe objectof cognition as distinct things, then we must conclude that the object of cognition is a mind-dependent construction. Constructivist readers mistakethe mind-dependent nature of our human cognitionof objects for theputative mind-dependent nature of the known object. The second reason is overintellectualization. Constructivist readers mistake the objectifying syntheses of the imagination, below the threshold of self-consciousness, for cognitive conceptual operations by means of which we cognize (erkennen) the objects of cognition, or so I shall argue.
The effect of leave policies on increasing fertility: a systematic review
Authors: Thomas Jac , Rowe Francisco , Williamson Paul , Lin Eric S. 
Published: August 2022

AbstractLow fertility is set to worsen economic problems in many developed countries, and maternity, paternity, and parental leave have emerged as key pro-natal policies. Gender inequity in the balance of domestic and formal work has been identified as a key driver of low fertility, and leave can potentially equalise this balance and thereby promote fertility. However, the literature contends that evidence for the effect of leave on fertility is mixed. We conduct the first systematic review on this topic. By applying a rigorous search protocol, we identify and review empirical studies that quantify the impact of leave policies on fertility. We focus on experimental or quasi-experimental studies that can identify causal effects. We identify 11 papers published between 2009 and 2019, evaluating 23 policy changes across Europe and North America from 1977 to 2009. Results are a mixture of positive, negative, and null impacts on fertility. To explain these apparent inconsistencies, we extend the conceptual framework of Lalive and Zweimüller (2009), which decomposes the total effect of leave on fertility into the “current-child” and “future-child” effects. We decompose these into effects on women at different birth orders, and specify types of study design to identify each effect. We classify the 23 studies in terms of the type of effect identified, revealing that all the negative or null studies identify the current-child effect, and all the positive studies identify the future-child or total effect. Since the future-child and total effects are more important for promoting aggregate fertility, our findings show that leave does in fact increase fertility when benefit increases are generous. Furthermore, our extensions to Lalive and Zweimüller’s conceptual framework provide a more sophisticated way of understanding and classifying the effects of pro-natal policies on fertility. Additionally, we propose ways to adapt the ROBINS-I tool for evaluating risk of bias in pro-natal policy studies.
Reconciling spectroscopy with dynamics in global potential energy surfaces: The case of the astrophysically relevant SiC2
Authors: Rocha C. M. R. , Linnartz H. , Varandas A. J. C. 
Published: August 2022

SiC2 is a fascinating molecule due to its unusual bonding and astrophysical importance. In this work, we report the first global potential energy surface (PES) for ground-state SiC2 using the combined-hyperbolic-inverse-power-representation method and accurate ab initio energies. The calibration grid data are obtained via a general dual-level protocol developed afresh herein that entails both coupled-cluster and multi-reference configuration interaction energies jointly extrapolated to the complete basis set limit. Such an approach is specially devised to recover much of the spectroscopy from the PES, while still permitting a proper fragmentation of the system to allow for reaction dynamics studies. Besides describing accurately the valence strongly bound region that includes both the cyclic global minimum and isomerization barriers, the final analytic PES form is shown to properly reproduce dissociation energies, diatomic potentials, and long-range interactions at all asymptotic channels, in addition to naturally reflect the correct permutational symmetry of the potential. Bound vibrational state calculations have been carried out, unveiling an excellent match of the available experimental data on c-SiC2(A11). To further exploit the global nature of the PES, exploratory quasi-classical trajectory calculations for the endothermic C2 + Si → SiC + C reaction are also performed, yielding thermalized rate coefficients for temperatures up to 5000 K. The results hint for the prominence of this reaction in the innermost layers of the circumstellar envelopes around carbon-rich stars, hence conceivably playing therein a key contribution to the gas-phase formation of SiC, and eventually, solid SiC dust.

Published: August 2022

Using bilayer graphene structures (L-type and disk-type structures), we numerically demonstrate a tunable single-band terahertz metamaterial absorber with nearly perfect (100%) absorption by continuously adjusting the graphene Fermi energy parameters to determine the maximum absorption rate, the corresponding center frequency, and bandwidth. Graphene distinct dielectric–metal transition properties make it possible to achieve tunable terahertz absorption. The maximum absorption rate increases from 18% to 100% when the Fermi energy is increased from 0.1 to 1 eV. At 1 eV, the absorption rate exceeds 90% in the range of 0.57–1.03 THz. The incident angle is also tested. When the angle is in the range of 60°, excellent adsorption performance is maintained.

Published: August 2022

Using classical molecular dynamics simulations, we investigate the dielectric properties at interfaces of water with graphene, graphite, hexane, and water vapor. For graphite, we compare metallic and nonmetallic versions. At the vapor–liquid water and hexane–water interfaces, the laterally averaged dielectric profiles are significantly broadened due to interfacial roughness and only slightly anisotropic. In contrast, at the rigid graphene surface, the dielectric profiles are strongly anisotropic and the perpendicular dielectric profile exhibits pronounced oscillations and sign changes. The interfacial dielectric excess, characterized by the shift of the dielectric dividing surface with respect to the Gibbs dividing surface, is positive for all surfaces, showing that water has an enhanced dielectric response at hydrophobic surfaces. The dielectric dividing surface positions vary significantly among the different surfaces, which points to pronounced surface-specific dielectric behavior. The interfacial repulsion of a chloride ion is shown to be dominated by electrostatic interactions for the soft fluid–fluid interfaces and by non-electrostatic Lennard-Jones interactions for the rigid graphene–water interface. A linear tensorial dielectric model for the ion–interface interaction with sharp dielectric interfaces located on the dielectric dividing surface positions works well for graphene but fails for vapor and hexane, because these interfaces are smeared out. The repulsion of chloride from the metallic and nonmetallic graphite versions differs very little, which reflects the almost identical interfacial water structure and can be understood based on linear continuum dielectric theory. Interface flexibility shows up mostly in the nonlinear Coulomb part of the ion–interface interaction, which changes significantly close to the interfaces and signals the breakdown of linear dielectric continuum theory.
Review on optical nonlinearity of group-IV semiconducting materials for all-optical processing

Published: August 2022

Group-IV semiconductor compounds with intense optical nonlinearity have emerged as a new branch of all-optical processing materials benefiting from the manufacturing compatibility with silicon electronic and photonic integrated circuits. Due to the chemical reforming on the bonding or precipitating feature of the compositional atoms in the membrane matrix, either the orbital hybridization or the quantum self-assembly of interstitial composites can be employed to reform the electronic and optical characteristics. The recent development on enhancing the nonlinear refractive indices of the group-IV semiconductor materials has revealed significant progress to accelerate the all-optical switching logic, which greatly reduces the energy consumption to enable the constitution of the advanced multi-logic gating and the entry-level photonic computing circuits. This work not only overviews the group-IV semiconductor photonic data processing elements but also prospects for the future direction of optical quantum computation and communication. To date, the nonlinear refractive indices of the group-IV semiconductor materials can be obtained as 10−8 to 10−16 cm2/W in the range between 300 and 10 000 nm in 2022. The wavelength conversion and data switching with bit rate beyond 25 Gbps have been achieved via nonlinear photonic waveguide components. By taking the non-stoichiometric SiC-made micro-ring waveguide as an example, the n2 as high as 3.05 × 10−14 cm2/W of the resonant SiC micro-ring gate is retrieved from the pump–probe analysis. The eye-diagram of the wavelength converted data in the micro-ring achieves its signal-to-noise and on/off-extinction ratios (SNR and ER) of 5.6 and 11.8 dB, while up to 25-Gbps all-optical data-format inversion with 4.8-dB SNR and 10.2-dB ER is also performed during an ultrafast switching within rising and falling time of less than 22 ps. Such all-optical data processing including both wavelength switching and format conversion in the highly nonlinear optical SiC waveguide resonator can achieve error-free operation with corresponding bit-error-ratios of lower than 1 × 10−5 at 25 Gbps after forward error correction.

Published: August 2022

Plasmon-mediated electrocatalysis based on plasmonic gold nanoparticles (Au NPs) has emerged as a promising approach to facilitate electrochemical reactions with the introduction of light to excite the plasmonic electrodes. We have investigated the electrochemical oxidation of 4-(hydroxymethyl)benzoic acid (4-HMBA) on gold (Au), nickel (Ni), and platinum (Pt) metal working electrodes in alkaline electrolytes. Au has the lowest onset potential for catalyzing the electrooxidation of 4-HMBA among the three metals in base, whereas Pt does not catalyze the electrooxidation of 4-HMBA under alkaline conditions, although it is conventionally a good electrocatalyst for alcohol oxidation. Both 4-carboxybenzaldehyde and terephthalic acid are detected as the products of electrochemical oxidation of 4-HMBA on the Au working electrode by high-performance liquid chromatography . The electrodeposited Au NPs on indium tin oxide (ITO)-coated glass is further utilized as the working electrode for the 4-HMBA electrooxidation. With its broad absorption in the visible and near-infrared range, we show that the Au NPs on the ITO electrode could enhance the electrochemical oxidation of 4-HMBA under green and red LED light illuminations (505 and 625 nm). A possible reaction mechanism is proposed for the electrochemical oxidation of 4-HMBA on Au working electrodes in an alkaline electrolyte.
Efficient computation of

We present efficient algorithms for computing the

-dimensional homogeneous and isotropic spaces. Such statistics appear throughout the physical sciences and provide a natural tool to describe stochastic processes. Typically, algorithms for computing the NPCF components have

N
is small. By projecting the statistic onto a suitably defined angular basis, we show that the estimators can be written in a separable form, with complexity

or

such harmonics gives states of definite combined angular momentum, forming a natural separable basis for the NPCF. As
N
and
D
grow, the number of basis components quickly becomes large, providing a practical limitation to this (and all other) approaches: However, the dimensionality is greatly reduced in the presence of symmetries; for example, isotropic correlation functions require only states of zero combined angular momentum. We provide a Julia package implementing our estimators and show how they can be applied to a variety of scenarios within cosmology and fluid dynamics. The efficiency of such estimators will allow higher-order correlators to become a standard tool in the analysis of random fields.
Reconstitution of the
S. aureus agr
quorum sensing pathway reveals a direct role for the integral membrane protease MroQ in pheromone biosynthesis

Published: August 2022

In
Staphylococcus aureus,
virulence is under the control of a quorum sensing (QS) circuit encoded in the accessory gene regulator (
agr
) genomic locus. Key to this pathogenic behavior is the production and signaling activity of a secreted pheromone, the autoinducing peptide (AIP), generated following the ribosomal synthesis and posttranslational modification of a precursor polypeptide, AgrD, through two discrete cleavage steps. The integral membrane protease AgrB is known to catalyze the first processing event, generating the AIP biosynthetic intermediate, AgrD (1–32) thiolactone. However, the identity of the second protease in this biosynthetic pathway, which removes an N-terminal leader sequence, has remained ambiguous. Here, we show that membrane protease regulator of
agr
QS (MroQ), an integral membrane protease recently implicated in the
agr
response, is directly involved in AIP production. Genetic complementation and biochemical experiments reveal that MroQ proteolytic activity is required for AIP biosynthesis in
agr
specificity group I and group II, but not group III. Notably, as part of this effort, the biosynthesis and AIP-sensing arms of the QS circuit were reconstituted together in vitro. Our experiments also reveal the molecular features guiding MroQ cleavage activity, a critical factor in defining
agr
specificity group identity. Collectively, our study adds to the molecular understanding of the
agr
response and
Staphylococcus aureus
virulence.
Discourse approaches to the study of dialogue and culture(s)
Authors: Okulska Urszula 
Published: August 2022

AbstractAs an Introduction to the present issue, this article explores the workings of discourse and dialogue in communicatingunityanddiversitythrough language in vast social and cultural contexts. In what follows, discourse analysis is presented as a dialogue-oriented field that arose at the crossroads of linguistics and social sciences to overcome the limitations of traditional, autonomous linguistics. The dialogic profile of discourse analysis is demonstrated along three exploratory vectors that recognise dialogism as an inseparable criterion in the study of discourse. Accordingly, it will be shown that dialogicity is what lies at the core of discourse organization, discourse practice and discourse worlds. The discussion of the dialogic provenance and orientation of discourse (analysis) is closed by the volume presentation.
Political dialogues in Argentina

Published: August 2022

AbstractThis study addresses positioning in dissention fragments in political interviews in the Argentine media. The aim is to disclose how participants position themselves and others, and the consequences this has on meaning making in the interaction. From a dialogic perspective and a discourse pragmatic approach, we use the tenets of Positioning Theory and the Appraisal framework in the analysis of the data. We base our research on an exploratory-interpretive paradigm that provides qualitative results. To examine the position of the interactants, our attention focuses on the interrelated components of positioning, and on the linguistic resources used by the participants. The results reveal the implications of positioning for the communication of diversity, the relationship between participants, and the building of tense or relaxed atmospheres.
