Structural and functional features of treatment‐resistant depression: A systematic review and exploratory coordinate‐based meta‐analysis of neuroimaging studies
Authors: Miola Alessandro , Meda Nicola , Perini Giulia , Sambataro Fabio 
Published: January 2023

ObjectivesA third of people suffering from major depressive disorder do not experience a significant improvement in their symptoms even after adequate treatment with two different antidepressant medications. This common condition, termed treatment‐resistant depression (TRD), severely affects the quality of life of millions of people worldwide, causing long‐lasting interpersonal problems and social costs. Given its epidemiological and clinical relevance and the little consensus on whether the neurobiological underpinnings of TRD differ from treatment‐sensitive depression (TSD), we sought to highlight the convergent morphometric and functional neuroimaging correlates of TRD.MethodsWe systematically reviewed the published literature on structural and resting‐state functional neuroimaging of TRD compared to TSD and healthy controls (HC) and performed exploratory coordinate‐based meta‐analyses (CBMA) of significant results separately for each modality and multimodally (“all‐effects”). CBMAs were also performed for each direction and combining both directions of group contrasts.ResultsOut of the initial 1929 studies, only eight involving 555 participants (189 patients with TRD, 156 with TSD, and 210 HC) were included. In all‐effects CBMA, precentral/superior frontal gyrus showed a significant difference between TRD and HC. Functional and structural imaging meta‐analyses did not yield statistically significant results. A marginally significant cluster of altered intrinsic activity was found between TRD and HC in the cerebellum/pons.ConclusionsFrontal, cerebellar, and brainstem functions can be involved in the pathophysiology of TRD. However, the design and heterogeneity of the (scarce) published literature hinder the generalizability of the findings.

AbstractIntroductionPolymorphous light eruption (PMLE) and chronic actinic dermatitis (CAD) have been classically described in White individuals, although recent studies have reported higher prevalence in patients with dark skin types, particularly African Americans.ObjectiveTo evaluate for differences in demographic, and clinical features between persons with light and dark skin types who have PMLE and CAD.MethodsRetrospective review of patients with PMLE and CAD who were diagnosed from January 1, 1998, through November 31, 2021, at a single academic dermatology center.Results/DiscussionA total of 844 patients (725 [85.9%] female; mean [SD] age of onset: 41.7 [16.9] years) were diagnosed with PMLE, and 60 patients (22 [36.6%] female; mean age, [SD]: 60.6 [10.6] years) of age at presentation, disease duration of 8.2 [7.3] years were diagnosed with CAD. Although just over 50% of the general clinic population was White, the prevalence of PMLE and CAD was significantly higher in dark‐skinned individuals compared to light‐skinned individuals (PMLE: 625 [74.0%] vs. 219 [25.9%], p value < .001; CAD: 43 [71.6%] vs. 17 [28.3%], p value = .003) respectively. The pinpoint papular variant of PMLE (PP‐PMLE) was predominantly seen in dark‐skinned individuals.ConclusionA substantial proportion of PMLE and CAD cases are present in dark‐skinned individuals. PP‐PMLE can be mistaken for lichen nitidus. As such, recognition of this entity is important for adequate evaluation and management of patients with PMLE.
Social pricing of luxury products in a distribution channel

Published: January 2023

AbstractThe proliferation of social networking platforms like Facebook, Twitter, Instagram, and TikTok has greatly facilitated social interactions among individuals, and thus their product consumption has become more visible to their peers. This enhanced visibility influences consumers' purchase decisions of luxury products because it affects social value derived from conspicuous consumption of these products. In this paper, we develop an analytical model to study the impact of such social technologies on social pricing of a manufacturer and a retailer offering luxury products along a distribution channel. Consumers exhibit conspicuous consumption preferences and are grouped into snobs and conformists: Snobs value product exclusivity, while conformists desire product popularity. We derive the following interesting results. First, a better social technology that leads to higher visibility for conspicuous consumption can either raise or lower the wholesale price and retail price. Second, the manufacturer may gain (lose) while the retailer may lose (gain) under a better social technology; that is, the manufacturer's and retailer's preferences regarding the level of a social technology may not be aligned. Third, the advancement of a social technology may harm consumer surplus. Lastly, we consider several model extensions to validate our findings in broader contexts.
Birational properties of tangent to the identity germs without non‐degenerate singular directions
Authors: Mongodi Samuele , Ruggiero Matteo 
Published: January 2023

AbstractWe provide a family of isolated tangent to the identity germs which possess only degenerate characteristic directions, and for which the lift of to any modification (with suitable properties) has only degenerate characteristic directions. This is in sharp contrast with the situation in dimension 2, where any isolated tangent to the identity germ admits a modification where the lift of has a non‐degenerate characteristic direction. We compare this situation with the resolution of singularities of the infinitesimal generator of , showing that this phenomenon is not related to the non‐existence of complex separatrices for vector fields of Gomez‐Mont and Luengo. Finally, we describe the set of formal ‐invariant curves, and the associated parabolic manifolds, using the techniques recently developed by López‐Hernanz et al.

AbstractThe fractional Laplacian , , and its generalizations to variable‐coefficient ‐order pseudodifferential operators , are studied in ‐Sobolev spaces of Bessel‐potential type . For a bounded open set , consider the homogeneous Dirichlet problem: in , in . We find the regularity of solutions and determine the exact Dirichlet domain (the space of solutions with ) in cases where has limited smoothness , for , . Earlier, the regularity and Dirichlet domains were determined for smooth by the second author, and the regularity was found in low‐order Hölder spaces for by Ros‐Oton and Serra. The ‐results obtained now when are new, even for . In detail, the spaces are identified as ‐transmission spaces , exhibiting estimates in terms of near the boundary.The result has required a new development of methods to handle nonsmooth coordinate changes for pseudodifferential operators, which have not been available before; this constitutes another main contribution of the paper.
Noise sensitivity of percolation via differential inequalities
Authors: Tassion Vincent , Vanneuville Hugo 
Published: January 2023

AbstractConsider critical Bernoulli percolation in the plane. We give a new proof of the sharp noise sensitivity theorem shown by Garban, Pete, and Schramm (Acta Math. 205 (2010), 19–104). Contrary to the previous approaches, we do not use any spectral tool. We rather study differential inequalities satisfied by a dynamical four‐arm event, in the spirit of Kesten's proof of scaling relations in Kesten (Comm. Math. Phys. 109 (1987), 109–156). We also obtain new results in dynamical percolation. In particular, we prove that the Hausdorff dimension of the set of times with both primal and dual percolation equals almost surely.
Dynamic asymptotic dimension and Matui's HK conjecture
Authors: Bönicke Christian , Dell'Aiera Clément , Gabe James , Willett Rufus 
Published: January 2023

AbstractWe prove that the homology groups of a principal ample groupoid vanish in dimensions greater than the dynamic asymptotic dimension of the groupoid (as a side‐effect of our methods, we also give a new model of groupoid homology in terms of the Tor groups of homological algebra, which might be of independent interest). As a consequence, the K‐theory of the ‐algebras associated with groupoids of finite dynamic asymptotic dimension can be computed from the homology of the underlying groupoid. In particular, principal ample groupoids with dynamic asymptotic dimension at most two and finitely generated second homology satisfy Matui's HK‐conjecture.We also construct explicit maps from the groupoid homology groups to the K‐theory groups of their ‐algebras in degrees zero and one, and investigate their properties.
Multiplicative chaos of the Brownian loop soup
Authors: Aïdékon Élie , Berestycki Nathanaël , Jego Antoine , Lupu Titus 
Published: January 2023

AbstractWe construct a measure on the thick points of a Brownian loop soup in a bounded domain of the plane with given intensity , which is formally obtained by exponentiating the square root of its occupation field. The measure is constructed via a regularisation procedure, in which loops are killed at a fix rate, allowing us to make use of the Brownian multiplicative chaos measures previously considered in Aïdékon et al. (Ann. Probab. 48 (2020), no. 4, 1785–1825), Bass et al. (Ann. Probab. 22 (1994), no. 2, 566–625) and Jego (Ann. Probab. 48 (2020), no. 4, 1597–1643), or via a discrete loop soup approximation. At the critical intensity , it is shown that this measure coincides with the hyperbolic cosine of the Gaussian free field, which is closely related to Liouville measure. This allows us to draw several conclusions which elucidate connections between Brownian multiplicative chaos, Gaussian free field and Liouville measure. For instance, it is shown that Liouville‐typical points are of infinite loop multiplicity, with the relative contribution of each loop to the overall thickness of the point being described by the Poisson–Dirichlet distribution with parameter . Conversely, the Brownian chaos associated to each loop describes its microscopic contribution to Liouville measure. Along the way, our proof reveals a surprising exact integrability of the multiplicative chaos associated to a killed Brownian loop soup. We also obtain some estimates on the discrete and continuous loop soups which may be of independent interest.

The process of [Formula: see text] is studied using [Formula: see text] [Formula: see text] Monte Carlo (MC) events at [Formula: see text] GeV with a fast simulation software at future Super Tau Charm Facility (STCF). The statistical sensitivity for CP violation is determined to be the order of [Formula: see text] by measuring the asymmetric parameters of the [Formula: see text] decay. Furthermore, the decay of [Formula: see text] also serves as a benchmark process to optimize the detector responses using the interface provided by the fast simulation software.
Combined magnetic field system for atom chips
Authors: Jia Xuemei , Xu Bowen , Zhou Shuyu , Wang Ying 
Published: January 2023

In this paper, we have developed a combined magnetic field system to explore an alternative technical route for the generation of Bose–Einstein condensates containing numerous atoms on an atom chip. The system is characterized by the fact that the quadrupole magnetic field required by the magneto-optic trap is generated by U-shaped current-carrying wires combined with bias magnetic fields, whereas the quadrupole magnetic field adopted for the magnetic trap is generated by anti-Helmholtz coils. By fine-tuning the bias magnetic fields, the collection of atoms in the mirror MOT and the loading of the quadrupole magnetic trap can be optimized. The initial number of [Formula: see text]Rb atoms in the magnetic trap is approximately [Formula: see text], and the lifetime of the atoms is over 30 s. This scheme can facilitate the chip-surface design and is suitable for the precise manipulation of Bose–Einstein condensates near the chip surface.
Inhomogeneous equation of state and its consequences in a coupled fluid scenario and realization of Little Rip, Pseudo Rip and Bounce cosmology
Authors: Chakraborty Gargee , Chattopadhyay Surajit 
Published: January 2023

Motivated by the work of P. H. Frampton et al. [Phys. Lett. B 708 (2012) 204; I. Brevik et al., Phys. Rev. D 84 (2011) 103508, arXiv:1107.4642 [hep-th]; I. Brevik et al., Phys. Rev. D 86 (2012) 063007, arXiv:1208.4770 [gr-qc]] this study reports on the reconstruction schemes for the inhomogeneous equation of state (EoS) first introduced by S. Nojiri et al., [Phys. Rev. D 72 (2005) 023003, arXiv:hep-th/0505215 [hep-th]] and the cosmology in the scenario of coupled fluid. We have considered the viscosity through the Eckart approach in an interacting system. The EoS parameter for the Little Rip, the [Formula: see text] in terms of cosmic time for Pseudo Rip, is reconstructed for the EoS for Bounce cosmology inhomogeneous viscous fluid. The EoS parameter is rebuilt for the coupled dark fluid in the nonviscous system for the Little Rip, Pseudo Rip and Bounce cosmology. The reconstructed EoS parameter for inhomogeneous viscous fluid was phantom for the Little Rip cosmology. The reconstructed EoS parameters of holographic Ricci dark energy (HRDE) of the coupled fluid in nonviscous systems are phantom for both the Little Rip and Pseudo Rip cosmology. The model HRDE of the coupled fluid in the nonviscous scenario for Pseudo-Rip cosmology indicates the possibility of singularity. The same model for the bounce cosmology violates the null energy condition and has the EoS parameter almost symmetric around the bouncing point.
WEAK ERROR RATES FOR OPTION PRICING UNDER LINEAR ROUGH VOLATILITY
Authors: BAYER CHRISTIAN , HALL ERIC JOSEPH , TEMPONE RAÚL 
Published: January 2023

In quantitative finance, modeling the volatility structure of underlying assets is vital to pricing options. Rough stochastic volatility models, such as the rough Bergomi model [C. Bayer, P. K. Friz & J. Gatheral (2016) Pricing under rough volatility, Quantitative Finance 16 (6), 887–904, doi:10.1080/14697688.2015.1099717], seek to fit observed market data based on the observation that the log-realized variance behaves like a fractional Brownian motion with small Hurst parameter, [Formula: see text], over reasonable timescales. Both time series of asset prices and option-derived price data indicate that [Formula: see text] often takes values close to [Formula: see text] or less, i.e. rougher than Brownian motion. This change improves the fit to both option prices and time series of underlying asset prices while maintaining parsimoniousness. However, the non-Markovian nature of the driving fractional Brownian motion in rough volatility models poses severe challenges for theoretical and numerical analyses and for computational practice. While the explicit Euler method is known to converge to the solution of the rough Bergomi and similar models, its strong rate of convergence is only [Formula: see text]. We prove rate [Formula: see text] for the weak convergence of the Euler method for the rough Stein–Stein model, which treats the volatility as a linear function of the driving fractional Brownian motion, and, surprisingly, we prove rate one for the case of quadratic payoff functions. Indeed, the problem of weak convergence for rough volatility models is very subtle; we provide examples demonstrating the rate of convergence for payoff functions that are well approximated by second-order polynomials, as weighted by the law of the fractional Brownian motion, may be hard to distinguish from rate one empirically. Our proof uses Talay–Tubaro expansions and an affine Markovian representation of the underlying and is further supported by numerical experiments. These convergence results provide a first step toward deriving weak rates for the rough Bergomi model, which treats the volatility as a nonlinear function of the driving fractional Brownian motion.
Lebanon’s Parliament System as a Form of Institutionalized Hybridity
Authors: Paterson James , MacQueen Ben 
Published: January 2023

Abstract
This article presents the Lebanese parliament as a form of institutionalized hybridity that offers a modicum of popular participation through highly regulated and moderated channels. It argues that the procedural nature of Lebanon’s electoral system is one that is largely, if not entirely, underscored by a closed elite bargaining process and is driven by elite preferences. This dynamic is a by-product of a power-sharing arrangement that ostensibly balances sectarian concerns, but in reality creates a disparity between political elites and the individuals within those sects which the consociational arrangement purports to include. However, this system has also created and reinforced challenges to its rule, particularly from below. With that in mind, this article highlights the evolving interactions between the entrenched, elite dominated, political system and popular protest movement and outlines how recent patterns of popular unrest present more fundamental critiques of the parliament and its central role in Lebanese politics.
Healthcare professionals’ perception of barriers and facilitators for care coordination of older adults with complex care needs being discharged from hospital: A qualitative comparative study of two Nordic capitals
Authors: Agerholm Janne , Jensen Natasja Koitzsch , Liljas Ann 
Published: January 2023

Abstract
Background
The handover of older adults with complex health and social care from hospital admissions to homebased healthcare requires coordination between multiple care providers. Providing insight to the care coordination from healthcare professionals’ views is crucial to show what efforts are needed to manage patient handovers from hospitals to home care, and to identify strengths and weaknesses of the care systems in which they operate.

Objective
This is a comparative study aiming to examine healthcare professionals’ perceptions on barriers and facilitators for care coordination for older patients with complex health and social care needs being discharged from hospital in two capital cities Copenhagen (DK) and Stockholm (SE).

Method
Semi-structured interviews were conducted with 25 nurses and 2 assistant nurses involved in the coordination of the discharge process at hospitals or in the home healthcare services (Copenhagen n = 11, Stockholm n = 16). The interview guide included questions on the participants’ contributions, responsibilities, and influence on decisions during the discharge process. They were also asked about collaboration and interaction with other professionals involved in the process. The data was analysed using thematic analysis.

Results
Main themes were communication ways, organisational structures, and supplementary work by staff. We found that there were differences in the organisational structure of the two care systems in relation to integration between different actors and differences in accessibility to patient information, which influenced the coordination. Municipal discharge coordinators visiting patients at the hospital before discharge and the follow-home nurse were seen as facilitators in Copenhagen. In Stockholm the shared information system with access to patient records were lifted as a facilitator for coordination. Difficulties accessing collaborators were experienced in both settings. We also found that participants in both settings to a high degree engage in work tasks outside of their responsibilities to ensure patient safety.

Conclusions
There are lessons to be learned from both care systems. The written e-communication between hospitals and home health care runs more smoothly in Stockholm, whereas it is perceived as a one-way communication in Copenhagen. In Copenhagen there are more sector-overlapping work which might secure a safer transition from hospital to home. Participants in both settings initiated own actions to weigh out imperfections of the system.

Published: January 2023

Abstract
Objective
Compared with other regions in the world, the transmission characteristics of the COVID-19 epidemic in Africa are more obvious, has a unique transmission mode in this region; At the same time, the data related to the COVID-19 epidemic in Africa is characterized by low data quality and incomplete data coverage, which makes the prediction method of COVID-19 epidemic suitable for other regions unable to achieve good results in Africa. In order to solve the above problems, this paper proposes a prediction method that nests the in-depth learning method in the mechanism model. From the experimental results, it can better solve the above problems and better adapt to the transmission characteristics of the COVID-19 epidemic in African countries.

Methods
Based on the SIRV model, the COVID-19 transmission rate and trend from September 2021 to January 2022 of the top 15 African countries (South Africa, Morocco, Tunisia, Libya, Egypt, Ethiopia, Kenya, Zambia, Algeria, Botswana, Nigeria, Zimbabwe, Mozambique, Uganda, and Ghana) in the accumulative number of COVID-19 confirmed cases was fitted by using the data from Worldometer. Non-autoregressive (NAR), Long-short term memory (LSTM), Autoregressive integrated moving average (ARIMA) models, Gaussian and polynomial functions were used to predict the transmission rate β in the next 7, 14, and 21 days. Then, the predicted transmission rate βs were substituted into the SIRV model to predict the number of the COVID-19 active cases. The error analysis was conducted using root-mean-square error (RMSE) and mean absolute percentage error (MAPE).

Results
The fitting curves of the 7, 14, and 21 days were consistent with and higher than the original curves of daily active cases (DAC). The MAPE between the fitted and original 7-day DAC was only 1.15% and increased with the longer of predict days. Both the predicted β and DAC of the next 7, 14, and 21 days by NAR and LSTM nested models were closer to the real ones than other three ones. The minimum RMSEs for the predicted number of COVID-19 active cases in the next 7, 14, and 21 days were 12,974, 14,152, and 12,211 people, respectively when the order of magnitude for was 106, with the minimum MAPE being 1.79%, 1.97%, and 1.64%, respectively.

Conclusion
Nesting the SIRV model with NAR, LSTM, ARIMA methods etc. through functionalizing β respectively could obtain more accurate fitting and predicting results than these models/methods alone for the number of confirmed COVID-19 cases in Africa in which nesting with NAR had the highest accuracy for the 14-day and 21-day predictions. The nested model was of high significance for early understanding of the COVID-19 disease burden and preparedness for the response.
