description: The use of machine learning techniques in classical and quantum systems has led to novel techniques to classify ordered and disordered phases, as well as uncover transition points in critical phenomena. Efforts to extend these methods to dynamical processes in complex networks is a field of active research. Network-percolation, a measure of resilience and robustness to structural failures, as well as a proxy for spreading processes, has numerous applications in social, technological, and infrastructural systems. A particular challenge is to identify the existence of a percolation cluster in a network in the face of noisy data. Here, we consider bond-percolation, and introduce a sampling approach that leverages the core-periphery structure of such networks at a microscopic scale, using onion decomposition, a refined version of the $k-$core. By selecting subsets of nodes in a particular layer of the onion spectrum that follow similar trajectories in the percolation process, percolating phases can be distinguished from non-percolating ones through an unsupervised clustering method. Accuracy in the initial step is essential for extracting samples with information-rich content, that are subsequently used to predict the critical transition point through the confusion scheme, a recently introduced learning method. The method circumvents the difficulty of missing data or noisy measurements, as it allows for sampling nodes from both the core and periphery, as well as intermediate layers. We validate the effectiveness of our sampling strategy on a spectrum of synthetic network topologies, as well as on two real-word case studies: the integration time of the US domestic airport network, and the identification of the epidemic cluster of COVID-19 outbreaks in three major US states. The method proposed here allows for identifying phase transitions in empirical time-varying networks.

description: Actinotaenium mooreanum (W.Archer) Teiling (1954: 408) (Figs 68–72)
Cells solitary, approximately 2 times longer than wide, widely elliptic, apices widely rounded; chloroplast stellate, two pyrenoids; zygospore subrectangular, dark brown, with rounded-acuminate papillae. Cells 16–20 μm long, 8–9 μm wide; zygospore 17–22 μm long, 11–14 μm wide.
 Material examined: BRAZIL, Bahia, Santa Teresinha, Serra da Jiboia. 14-I-2015, G. J. P. Ramos et al. s/n (HUEFS 224661), 18-VII-2015, G. J. P. Ramos et al. s/n (HUEFS 224679), 11-IX-2015, G. J. P. Ramos et al. s/n (HUEFS 224705), 20-XI-2015, G. J. P. Ramos et al. s/n (HUEFS 224721).
 Habitat: bromeliad tanks (Alcantarea nahoumii); T 26.1 (± 3.9 ºC). pH 5.9 (± 0.6). C 0.24 (± 0.18 mS. cm-1). TDS 0.11 (± 0.09 ppt). DO 6.4 (± 0.8 mg.L- 1).
 Notes: Actinotaenium mooreanum is reported here for the first time for South America; with previous records only from Europe and Oceania (Guiry & Guiry 2017). During our analysis, we commonly found zygospores of this species—usually in groups associated with the mucilaginous sheaths of cyanobacteria. According to Růžička (1981), this species prefers slightly acidic to neutral environments (pH 4.9–7.5), similar to conditions found in bromeliad tanks.

description: Coherent neural spiking and local field potentials are believed to be signatures of the binding and transfer of information in the brain. Coherent activity has now been measured experimentally in many regions of mammalian cortex. Synfire chains are one of the main theoretical constructs that have been appealed to to describe coherent spiking phenomena. However, for some time, it has been known that synchronous activity in feedforward networks asymptotically either approaches an attractor with fixed waveform and amplitude, or fails to propagate. This has limited their ability to explain graded neuronal responses. Recently, we have shown that pulse-gated synfire chains are capable of propagating graded information coded in mean population current or firing rate amplitudes. In particular, we showed that it is possible to use one synfire chain to provide gating pulses and a second, pulse-gated synfire chain to propagate graded information. We called these circuits synfire-gated synfire chains (SGSCs). Here, we present SGSCs in which graded information can rapidly cascade through a neural circuit, and show a correspondence between this type of transfer and a mean-field model in which gating pulses overlap in time. We show that SGSCs are robust in the presence of variability in population size, pulse timing and synaptic strength. Finally, we demonstrate the computational capabilities of SGSC-based information coding by implementing a self-contained, spike-based, modular neural circuit that is triggered by, then reads in streaming input, processes the input, then makes a decision based on the processed information and shuts itself down.

description: Leveraging one-sided RDMA for applications that replicate small data objects can be surprisingly difficult: such uses amplify any protocol overheads. Spindle is a set of optimization techniques for systematically tackling this class of challenges for atomic multicast over RDMA. These include memory polling optimizations using novel sender and receiver batching techniques, null-message send logic, and improved multi-thread synchronization. We applied Spindle to Derecho, an open-source C++ library for atomic multicast, and obtained significant performance improvements both for the library itself and for an OMG-compliant avionics DDS built over Derecho. Derecho's multicast bandwidth utilization for 10KB messages rose from 1GB/s to 9.7GB/s on a 12.5GB/s network, and it became more robust to delays. Interestingly, although some of our techniques employ batching, latency dropped by nearly two orders of magnitude. Spindle optimizations should also be of value in other RDMA applications limited by the speed of coordination.

description: Background: One key approach for anticancer therapy is drug combination. Drug combinations can help reduce doses and thereby decrease side effects. Furthermore, the likelihood of drug resistance is reduced. Distinct alterations in tumor metabolism have been described in past decades, but metabolism has yet to be targeted in clinical cancer therapy. Recently, we found evidence for synergism between dichloroacetate (DCA), a pyruvate dehydrogenase kinase inhibitor, and the HIF-1 alpha inhibitor PX-478. In this study, we aimed to analyse this synergism in cell lines of different cancer types and to identify the underlying biochemical mechanisms. Methods: The dose-dependent antiproliferative effects of the single drugs and their combination were assessed using SRB assays. FACS, Western blot and HPLC analyses were performed to investigate changes in reactive oxygen species levels, apoptosis and the cell cycle. Additionally, real-time metabolic analyses (Seahorse) were performed with DCA-treated MCF-7 cells. Results: The combination of DCA and PX-478 produced synergistic effects in all eight cancer cell lines tested, including colorectal, lung, breast, cervical, liver and brain cancer. Reactive oxygen species generation and apoptosis played important roles in this synergism. Furthermore, cell proliferation was inhibited by the combination treatment. Conclusions: Here, we found that these tumor metabolism-targeting compounds exhibited a potent synergism across all tested cancer cell lines. Thus, we highly recommend the combination of these two compounds for progression to in vivo translational and clinical trials.

description: Gene and genome duplications have an important role in evolution as a mechanism that creates novel genetic material. Paralogues created by duplication can diversify in function and contribute to the complexity of genetic networks, especially in the context of the gene regulation and signalling pathways that control animal development. Clusters of related genes that have arisen by tandem duplication illustrate the role of regulatory elements in preserving synteny by constraining gene neighbourhoods. Whole genome duplications have occurred on the stems of lineages characterised by the evolution of novel structures, adaptations to different environments, and species diversity. Here, I aim to understand how gene and genome duplications have impacted specific developmental gene families and processes throughout animal evolution with a comparative genomics approach. I make use of genomic resources from phylogenetically informative lineages, including new genomes of early-branching chordates, spiralians, and ecdysozoans. I have examined the impact of the vertebrate two rounds of whole genome duplication on chordate muscle development including the highly conserved family of myogenic regulatory factors and muscle gene expression. I have also investigated the evolution of homeobox gene families, with a focus on clusters of genes found across bilaterians, and specifically focus on the Hox cluster. With phylogenetic and synteny analyses, I found that a tandem duplication underpins the origin of two vertebrate muscle gene types. I examined the impact of whole genome duplication on a diversity of genes encoding proteins in a highly conserved signalling pathway in muscle, and I surveyed and revised the hypotheses for the evolution of homeobox genes across the bilaterians. In doing so, I have also generated a large resource of genomic annotations and protein sequences to facilitate functional studies in the future. These findings not only have identified certain duplications that have underpinned certain known instances of subfunctionalisation among paralogues, but also indicate gene families to target for future study.

description: The distribution of effect sizes may offer insights about the research done and reported in a scientific field. We have evaluated 12 412 manually collected correlation effect sizes (Sample 1) and 31 157 computer-extracted correlation effect sizes (Sample 2) published in journals focused on social or developmental psychology. Sample 1 consisted of 243 studies from six journals published in 2010 and 2019. Sample 2 consisted of 5012 papers published in 10 journals between 2010 and 2019. The 25th, 50th and 75th effect size percentiles were 0.08, 0.17 and 0.33, and 0.17, 0.31 and 0.52 in Samples 1 and 2, respectively. Sample 2 percentiles were probably larger because Sample 2 only included effect sizes from the text but not from tables. In text authors may have emphasized larger correlations. Large sample sizes were associated with smaller reported correlations. In Sample 1 about 70% of studies specified a directional hypothesis. In 2010 no papers had power calculations, while in 2019 14% of papers had power calculations. These data offer empirical insights into the distribution of reported correlations and may inform the interpretation of effect sizes. They also demonstrate the importance of computation of statistical power and highlight potential reporting bias.

description: We study the problem of measuring errors in non-trace-preserving quantum operations, with a focus on their impact on quantum computing. We propose an error metric that efficiently provides an upper bound on the trace distance between the normalized output states from imperfect and ideal operations, while remaining compatible with the diamond distance. As a demonstration of its application, we apply our metric in the analysis of a lossy beam splitter and a nondeterministic conditional sign-flip gate, two primary non-trace-preserving operations in the Knill-Laflamme-Milburn protocol. We then turn to the leakage errors of neutral-atom quantum computers, finding that these errors scale worse than previously anticipated, implying a more stringent fault-tolerant threshold. We also assess the quantum Zeno gate's error using our metric. In a broader context, we discuss the potential of our metric to analyze general postselected protocols, where it can be employed to study error propagation and estimate thresholds in fault-tolerant quantum computing. The results highlight the critical role of our proposed error metric in understanding and addressing challenges in practical quantum information processing.

description: We present CCD $UBVRI$ photometry of the field of the open cluster NGC 6866. Structural parameters of the cluster are determined utilizing the stellar density profile of the stars in the field. We calculate the probabilities of the stars being a physical member of the cluster using their astrometric data and perform further analyses using only the most probable members. The reddening and metallicity of the cluster were determined by independent methods. The LAMOST spectra and the ultraviolet excess of the F and G type main-sequence stars in the cluster indicate that the metallicity of the cluster is about the solar value. We estimated the reddening $E(B-V)=0.074 \pm 0.050$ mag using the $U-B$ vs $B-V$ two-colour diagram. The distance modula, the distance and the age of NGC 6866 were derived as $μ= 10.60 \pm 0.10$ mag, $d=1189 \pm 75$ pc and $t = 813 \pm 50$ Myr, respectively, by fitting colour-magnitude diagrams of the cluster with the PARSEC isochrones. The Galactic orbit of NGC 6866 indicates that the cluster is orbiting in a slightly eccentric orbit with $e=0.12$. The mass function slope $x=1.35 \pm 0.08$ was derived by using the most probable members of the cluster.

description: Due to its enhanced accessibility and visibility, pXRF has recently permeated the field of biological anthropology. The emerging applications have ranged from the detection of heavy metals like Mercury, Lead, and Iron, to the analysis of paleodiets, to the comparisons of trace elements for the purpose of resolving commingling. The purpose of this thesis is to outline the theory, advantages, and realistic limitations of current pXRF equipment and methodologies in the resolution of commingled skeletal remains. The discussion will: (1) introduce the underlying theory of pXRF in the context of the commingling of human remains, (2) summarize and evaluate the past applications of spectrometry to the study of human remains, and (3) outline a collection of successful approaches for future projects as well as research frontiers which are yet unexplored.

description: The Midwest Archeological Center conducted field investigations at Lincoln Home National Historic Site in Springfield, Illinois in 2005 and 2006 in conjunction with the preparation of Historic Structure Reports on two of the houses that originally stood in the Abraham Lincoln neighborhood in close proximity to the Lincoln Home itself, the Carrigan house immediately next door to the north and the Burch house directly across Eighth Street to the west. An archeological inventory and evaluation of each of those two properties was undertaken for two purposes: 1) to collect archeological data that would be considered in combination with historic archival documentation to determine if sufficient information exists to enable the accurate reconstruction of the two houses, and 2) to assess the potential impact of reconstruction on any significant historic archeological resources present on the two properties. Multiple episodes of building construction, modification, adaptive reuse, repair, and demolition have taken place at the two properties over the past 150 years, resulting in an archeological record that is complicated, particularly at Carrigan. Substantial remains of the Carrigan house and associated features were identified during the project, including foundation walls, several cellars, an intact cistern, and the possible remains of corner supports or shallow foundations for two outbuildings. When the Carrigan house was replaced by a second house in 1879, elements of the original structure were incorporated into the new one in areas where the footprints of the two houses overlapped, serving to preserve many of the Carrigan features that probably otherwise would not have survived. Much of the Burch property was found to have been heavily disturbed by the construction and later demolition of two early twentieth century commercial buildings and an apartment house. Nevertheless, two remnant sections of the north Burch house foundation were identified together with two chimney-related features and a small interior well. The truncated lower portion of a mortar-lined cistern was also identified immediately outside the projected location of the southwest corner of the house. Recommendations for management of the archeological resources on the Carrigan and Burch properties are provided. Several possible directions for future archeological research are suggested.

description: Background: Radiographs of the sacroiliac joints are commonly used for the diagnosis and classification of axial spondyloarthritis. The aim of this study was to develop and validate an artificial neural network for the detection of definite radiographic sacroiliitis as a manifestation of axial spondyloarthritis (axSpA). Methods: Conventional radiographs of the sacroiliac joints obtained in two independent studies of patients with axSpA were used. The first cohort comprised 1553 radiographs and was split into training (n = 1324) and validation (n = 229) sets. The second cohort comprised 458 radiographs and was used as an independent test dataset. All radiographs were assessed in a central reading session, and the final decision on the presence or absence of definite radiographic sacroiliitis was used as a reference. The performance of the neural network was evaluated by calculating areas under the receiver operating characteristic curves (AUCs) as well as sensitivity and specificity. Cohen's kappa and the absolute agreement were used to assess the agreement between the neural network and the human readers. Results: The neural network achieved an excellent performance in the detection of definite radiographic sacroiliitis with an AUC of 0.97 and 0.94 for the validation and test datasets, respectively. Sensitivity and specificity for the cut-off weighting both measurements equally were 88% and 95% for the validation and 92% and 81% for the test set. The Cohen's kappa between the neural network and the reference judgements were 0.79 and 0.72 for the validation and test sets with an absolute agreement of 90% and 88%, respectively. Conclusion: Deep artificial neural networks enable the accurate detection of definite radiographic sacroiliitis relevant for the diagnosis and classification of axSpA.

description: We examine an unexpected but significant source of positive public health messaging during the COVID-19 pandemic -- K-pop fandoms. Leveraging more than 7 million tweets related to mask-wearing and K-pop between March 2020 and December 2021, we analyzed the online spread of the hashtag \#WearAMask and vaccine-related tweets amid anti-mask sentiments and public health misinformation. Analyses reveal the South Korean boyband BTS as one of the most significant driver of health discourse. Tweets from health agencies and prominent figures that mentioned K-pop generate 111 times more online responses compared to tweets that did not. These tweets also elicited strong responses from South America, Southeast Asia, and rural States -- areas often neglected in Twitter-based messaging by mainstream social media campaigns. Network and temporal analysis show increased use from right-leaning elites over time. Mechanistically, strong-levels of parasocial engagement and connectedness allow sustained activism in the community. Our results suggest that public health institutions may leverage pre-existing audience markets to synergistically diffuse and target under-served communities both domestically and globally, especially during health crises such as COVID-19.

description: The problem of a cold gas flowing past a stationary object is considered. It is shown that at large distances from the obstacle the shock front forms a parabolic solid of revolution. The interior of the shock front is obtained by solution of the hydrodynamic equations in parabolic coordinates. The results are verified with a hydrodynamic simulation. The drag force and expected spectra are calculated for such shock, both in case of an optically thin and thick media. Finally, relations to astrophysical bow shocks and other analytic works on oblique shocks are discussed.

description: Over time, travel between continents has become easier, allowing many diseases and pests to leave their native habitats, sometimes with disastrous results. Famous examples include the chestnut blight and woolly adelgids, which have greatly harmed ecosystems in the United States. I investigated the factors that allow these invasive species to flourish in non-native environments by examining how a plant’s susceptibility to pathogens depends on its phylogeny, traits, and native geographic range. To do so, I used grasses that varied widely across these three factors in an observational field study and in vitro inoculation experiment. Collected susceptibility data was compared to traits like leaf mass per area (LMA), growth rate, and photosynthetic rate. Initial results indicate significant susceptibility differences among different grass species. The results will help illuminate what allows pathogens to infect new hosts, allowing planning for the prevention and mitigation of species invasion.

description: Background: Homelessness is often described as both a driver and a consequence of poor health, social exclusion and economic marginalisation. The present protocol provides a detailed description of the study Examining the health situation of homeless people in Berlin: a retrospective analysis of data from the health centre for the homeless of the Jenny De la Torre Foundation from 2006 to 2020 (GIG study). The primary objective of the GIG study is to describe and analyse the social and health situation of homeless people in Berlin. Methods: A retrospective secondary data analysis of an anonymous full census of medical records for the years 2006 until 2020 from a health centre for homeless people will be carried out. The main outcome is the description and analysis of the social and health situation of homeless people in Berlin. Total and cross-sectional sample characteristics will be presented in a descriptive analysis using Chi-Square Test, Mann-Whitney-U-Test or independent t-Test as appropriate to test (sub) group differences. Further, outcomes will be analysed using finite mixture modelling in order to distinguish different types of social and health conditions. Latent variable regressions will be applied in order to identify sociodemographic and disease-related factors associated with decreasing health conditions. Discussion: Given the high number of homeless individuals in Germany, it is of great importance to examine their social and health situation in order to gain a better understanding of challenges and needs of homeless people and work on new approaches and solutions to effectively address these. Trail registration: The study was prospectively registered with the German Clinical Trials Register (trial registration number: DRKS00021172). Registered 26 June 2020.

description: A memetic framework for optimal inverse design is proposed by combining a local gradient-based procedure and a robust global scheme. The procedure is based on method-of-moments matrices and does not demand full inversion of a system matrix. Fundamental bounds are evaluated for all optimized metrics in the same manner, providing natural stopping criteria and quality measures for realized devices. Compared to density-based topology optimization, the proposed routine does not require filtering or thresholding. Compared to commonly used heuristics, the technique is significantly faster, still preserving a high level of versatility and robustness. This is a two-part paper in which the first part is devoted to the theoretical background and properties, and the second part applies the method to examples of varying complexity.

description: Optimal inverse design, including topology optimization and evaluation of fundamental bounds on performance, which was introduced in Part~1, is applied to various antenna design problems. A memetic scheme for topology optimization combines local and global techniques to accelerate convergence and maintain robustness. Method-of-moments matrices are used to evaluate objective functions and allow to determine fundamental bounds on performance. By applying the Shermann-Morrison-Woodbury identity, the repetitively performed structural update is inversion-free yet full-wave. The technique can easily be combined with additional features often required in practice, \eg{}, only a part of the structure is controllable, or evaluation of an objective function is required in a subdomain only. The memetic framework supports multi-frequency and multi-port optimization and offers many other advantages, such as an actual shape being known at every moment of the optimization. The performance of the method is assessed, including its convergence and computational cost.

description: Direct evidence of excitation of the 5p3/2 -> 6p3/2 electric dipole forbidden transition in atomic rubidium is presented. The experiments were performed in a room temperature rubidium cell with continuous wave extended cavity diode lasers. Optical-optical double resonance spectroscopy with counterpropagating beams allows the detection of the non-dipole transition free of Doppler broadening. The 5p3/2 state is prepared by excitation with a laser locked to the maximum F cyclic transition of the D2 line, and the forbidden transition is produced by excitation with a 911 nm laser. Production of the forbidden transition is monitored by detection of the 420 nm fluorescence that results from decay of the 6p3/2 state. Spectra with three narrow lines (~ 13 MHz FWHM) with the characteristic F - 1, F and F + 1 splitting of the 6p3/2 hyperfine structure in both rubidium isotopes were obtained. The results are in very good agreement with a direct calculation that takes into account the 5s -> 5p3/2 preparation dynamics, the 5p3/2 -> 6p3/2 non-dipole excitation geometry and the 6p3/2 -> 5s1/2 decay. The comparison also shows that the electric dipole forbidden transition is a very sensitive probe of the preparation dynamics.

description: In this paper, we develop a dynamical system counterpart to the term sparsity sum-of-squares (TSSOS) algorithm proposed for static polynomial optimization. This allows for computational savings and improved scalability while preserving convergence guarantees when sum-of-squares methods are applied to problems from dynamical systems, including the problems of approximating region of attraction, the maximum positively invariant set, and the global attractor. At its core, the method exploits the algebraic structure of the data, thereby complementing existing methods that exploit causality relations among the states of the dynamical system. The procedure encompasses sign symmetries of the dynamical system as was already revealed for polynomial optimization. Numerical examples demonstrate the efficiency of the approach in the presence of this type of sparsity.

description: Background: The study analyzes changes in lung function, pulmonary pressure and diffusing capacity of the lung in patients with mitral valve regurgitation (MR) treated by MitraClip implantation. Methods: A total of 43 patients (19 women and 24 men with an average age of 78.0 +/- 6.6 years) who were able to perform pulmonary function testing including diffusing capacity of the lung for carbon monoxide (DLCO), vital capacity (VC), total lung capacity (TLC), residual volume (RV) and forced expiratory volume in 1 s (FEV1) before and 6 weeks after MitraClip implantation participated in this study. Furthermore, clinical and echocardiographic parameters including systolic pulmonary artery pressure (sPAP), left ventricular ejection fraction (LVEF) and left atrial diameter (LAD) measurements were recorded in all patients. Results: The procedure was performed successfully in all 43 patients leading to a reduction of MR in 97.7% of cases. One patient died on day 4 after the intervention most likely due to pulmonary artery embolism. Six weeks after the implantation 79.1% of patients showed a MR of at most mild to moderate. Furthermore, we could demonstrate a significant reduction of systolic pulmonary artery pressure during follow-up (from 48.8 +/- 11.4 mmHg to 42.9 +/- 9.0 mmHg (t(41) = - 2.6, p = 0.01). However, no changes in LVEF were detected. Comparing pre and post implant lung function tests, no significant alterations were seen for VC, TLC, DLCO and FEV1. Though, in a subgroup of patients with moderate to severe preexisting deterioration of DLCO at the baseline (max. 50%) the MitraClip procedure resulted in a significant improvement in DLCO (37.8% +/- 9.0 to 41.6% +/- 10.0, p < 0.001). Conclusions: Treatment of MR with the MitraClip system successfully reduces MR severity in the vast majority of patients. Consecutively, a reduction in pulmonary pressure could be observed, however no changes in LVEF were obvious. Lung function tests remained unaltered during follow-up. However, in a subgroup of patients with severe preexisting deterioration of DLCO the MitraClip procedure resulted in a significant improvement in DLCO.

description: We present a general framework for quantum interference (QI) between multiple, fundamentally different processes. Our framework reveals the importance of shaped input wavefunctions in enabling QI, and predicts unprecedented interactions between free electrons, bound electrons, and photons: (i) the vanishing of the zero-loss peak by destructive QI when a shaped electron wavepacket couples to light, under conditions where the electron's zero-loss peak otherwise dominates; (ii) QI between free electron and atomic (bound electron) spontaneous emission processes, which can be significant even when the free electron and atom are far apart, breaking the common notion that electron and atom must be close by to significantly affect each other's processes. Our work shows that emerging quantum waveshaping techniques unlock the door to greater versatility in light-matter interactions and other quantum processes in general.

The Reply of the Evangelical Mind: Responding to Mark Noll's "Scandal"
Creators: name: Tilley, Nathan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Writing in 1994 from Wheaton College, evangelical historian Mark Noll made the
following comment: “The scandal of the evangelical mind is that there is not much of an
evangelical mind.” However one might assess the merits of his claim at the time, evangelical
scholars from diverse fields and institutions rose to the challenge and responded with a number
of books suggesting solutions. Following Noll’s “epistle from a wounded lover” to fellow
evangelicals, a small, but significant movement of evangelical thinkers coalesced around
discussion of the meaning of Christian thinking and set out to challenge fellow believers to
renewed intellectual life.
Determinants of Laplacians for constant curvature metrics with three conical singularities on 2-sphere

description: We deduce an explicit closed formula for the zeta-regularized spectral determinant of the Friedrichs Laplacian on the Riemann sphere equipped with arbitrary constant curvature (flat, spherical, or hyperbolic) metric having three conical singularities of order $β_j\in(-1,0)$ (or, equivalently, of angle $2π(β_j+1)$). We show that among the metrics with a fixed value of the sum $β_1+β_2+β_3$ and a fixed surface area, those with $β_1=β_2=β_3$ correspond to a stationary point of the determinant. If, in addition, the surface area is sufficiently small, then the stationary point is a minimum. As a crucial step towards obtaining these results we find a relation between the determinant of Laplacian and the Liouville action introduced by A. Zamolodchikov and Al. Zamolodchikov in connection with the celebrated DOZZ formula for the three-point structure constants of the Liouville field theory.
