description: We address the determination of the time resolution for the $\rm 100~μm$ 4H-SiC PIN detectors fabricated by Nanjing University (NJU). The time response to $\rm β$ particles from a $\rm ^{90}$Sr source is investigated for the detection of the minimum ionizing particles (MIPs). We study the influence of different reverse voltages, which correspond to different carrier velocities and device sizes, and how this correlates with the detector capacitance. We determine a time resolution $\rm (94\pm1)~ps$ for $\rm 100~μm$ 4H-SiC PIN detector. A fast simulation software, termed RASER (RAdiation SEmiconductoR), is developed, and validated by comparing the waveform obtained from simulated and measured data. The simulated time resolution is $\rm (73\pm 1)~ps$ after considering the intrinsic leading contributions of the detector to time resolution.

description: The search of an unstructured database amounts to finding one element having a certain property out of $N$ elements. The classical search with an oracle checking one element at a time requires on average $N/2$ steps. The Grover algorithm for the quantum search, and its unitary Hamiltonian evolution analogue, accomplish the search asymptotically optimally in $\mathcal{O} (\sqrt{N})$ time steps. We reformulate the search problem as a dissipative Markov process acting on an $N$-level system weakly coupled to a thermal bath. Assuming that the energy levels of the system represent the database elements, we show that, with a proper choice of the spectrum and physically admissible, long-range transition rates between the energy levels, the system relaxes to the ground state, corresponding to the sought element, in time $\mathcal{O} (\ln N)$.

description: This study reports a biogenic approach to the synthesis of Au@CeO2 nanocomposite using electrochemically active biofilms (EABs) in water under normal pressure and 30°C. This work presents the results of extensive morphological, structural, optical, visible light photoelectrochemical and photocatalytic studies of Au@CeO2 nanocomposite. The presence of a large number of interfaces between Au nanoparticles and CeO2 for charge transfer is believed to play a key role in enhancing the optical and visible light photoelectrochemical and photocatalytic performance of Au@CeO2 nanocomposite. The enhanced visible light degradation of methyl orange and methylene blue by Au@CeO2 nanocomposite was much higher than that by pure CeO2. The reusability, stability, and other results suggests that the Au@CeO2 nanocomposite could be exploited as potential candidates for visible light photocatalysis, photovoltaic, and photoelectrochemical devices.

description: The Batalin-Vilkovisky data for Polyakov string theory on a manifold with (non-null) boundary is shown to induce compatible Batalin--Fradkin--Vilkovisky data, thus allowing BV-quantisation on manifolds with boundary. On the other hand, the analogous formulation of Nambu--Goto string theory fails to satisfy the needed regularity requirements. As a byproduct, a concise description is given of the reduced phase spaces of both models and their relation, for any target $d$-dimensional Lorentzian manifold.

Hypothesis Testing for Hierarchical Structures in Cognitive Diagnosis Models

Subjects: subject: Methodology (stat.ME)

description: Cognitive Diagnosis Models (CDMs) are a special family of discrete latent variable models widely used in educational, psychological and social sciences. In many applications of CDMs, certain hierarchical structures among the latent attributes are assumed by researchers to characterize their dependence structure. Specifically, a directed acyclic graph is used to specify hierarchical constraints on the allowable configurations of the discrete latent attributes. In this paper, we consider the important yet unaddressed problem of testing the existence of latent hierarchical structures in CDMs. We first introduce the concept of testability of hierarchical structures in CDMs and present sufficient conditions. Then we study the asymptotic behaviors of the likelihood ratio test (LRT) statistic, which is widely used for testing nested models. Due to the irregularity of the problem, the asymptotic distribution of LRT becomes nonstandard and tends to provide unsatisfactory finite sample performance under practical conditions. We provide statistical insights on such failures, and propose to use parametric bootstrap to perform the testing. We also demonstrate the effectiveness and superiority of parametric bootstrap for testing the latent hierarchies over non-parametric bootstrap and the naïve Chi-squared test through comprehensive simulations and an educational assessment dataset.

description: In this study, pure ZnO, CeO2 and ZnO/CeO2 nanocomposites were synthesized using a thermaldecomposition method and subsequently characterized using different standard techniques. High resolution X-ray photoelectron spectroscopy measurements confirmed the oxidation states and presence of Zn2+, Ce4+, Ce3+ and different bonded oxygen species in the nanocomposites. The prepared pure ZnO and CeO2 as well as the ZnO/CeO2 nanocomposites with various proportions of ZnO andCeO2 were tested for photocatalytic degradation of methyl orange, methylene blue and phenol under visible-light irradiation. The optimized and highly efficient ZnO/CeO2 (90:10) nanocomposite exhibited enhanced photocatalytic degradation performance for the degradation of methyl orange, methylene blue, and phenol as well as industrial textile effluent compared to ZnO, CeO2 and the otherinvestigated nanocomposites. Moreover, the recycling results demonstrate that the ZnO/CeO2 (90:10)nanocomposite exhibited good stability and long-term durability. Furthermore, the prepared ZnO/CeO2nanocomposites were used for the electrochemical detection of uric acid and ascorbic acid. The ZnO/CeO2 (90:10) nanocomposite also demonstrated the best detection, sensitivity and performance among the investigated materials in this application. These findings suggest that the synthesized ZnO/CeO2 (90:10) nanocomposite could be effectively used in various applications.

description: Short-term memory can be disrupted by task-irrelevant sound. Auditory distraction has been globally studied under the lens of two main phenomena: the deviation effect and the changing-state effect. Yet, it remains unclear whether they rely on common cerebral mechanisms and, concomitantly, what psychophysiological responses they can trigger. This scoping review provides a state of knowledge regarding psychophysiological indices of auditory distraction. Records published between 2001 and 2021 on the deviation effect and the changing-state effect with psychophysiological measures were extracted from PubMed, ERIC, PsycNet, Web of Science, and ScienceDirect. Records investigating task-relevant sounds, as well as those that failed to observe performance disruption, or to include a control condition or a concurrent cognitive task, were excluded from the review. The Revised Cochrane risk-of-bias tool for randomized trials was used for bias evaluation. Fifteen records were reviewed, mainly characterized by randomization, measurement and selection of results biases. Some markers were specific to the distraction type, but nonspecific responses were also found. Overall, we outline the main markers used to index auditory distraction, present their meaning for understanding underpinning mechanisms, and discuss implications and knowledge gaps that need to be filled to fully exploit psychophysiology for auditory distraction research.

description: Given an undirected, anonymous, port-labeled graph of $n$ memory-less nodes, $m$ edges, and degree $Δ$, we consider the problem of dispersing $k\leq n$ robots (or tokens) positioned initially arbitrarily on one or more nodes of the graph to exactly $k$ different nodes of the graph, one on each node. The objective is to simultaneously minimize time to achieve dispersion and memory requirement at each robot. If all $k$ robots are positioned initially on a single node, depth first search (DFS) traversal solves this problem in $O(\min\{m,kΔ\})$ time with $Θ(\log(k+Δ))$ bits at each robot. However, if robots are positioned initially on multiple nodes, the best previously known algorithm solves this problem in $O(\min\{m,kΔ\}\cdot \log \ell)$ time storing $Θ(\log(k+Δ))$ bits at each robot, where $\ell\leq k/2$ is the number of multiplicity nodes in the initial configuration. In this paper, we present a novel multi-source DFS traversal algorithm solving this problem in $O(\min\{m,kΔ\})$ time with $Θ(\log(k+Δ))$ bits at each robot, improving the time bound of the best previously known algorithm by $O(\log \ell)$ and matching asymptotically the single-source DFS traversal bounds. This is the first algorithm for dispersion that is optimal in both time and memory in arbitrary anonymous graphs of constant degree, $Δ=O(1)$. Furthermore, the result holds in both synchronous and asynchronous settings.

Three-dimensional Yang-Mills Chern-Simons theory from D3-brane background with D-instantons

description: By constructing the configuration of D3-branes with D(-1)-branes as D-instantons, we study the three-dimensional Yang-Mills Chern-Simons theory in holography. Due to the presence of the D-instantons, the D7-branes with discrepant embedding functions are able to be introduced in order to include the fundamental fermions (as flavors) and the Chern-Simons term (at very low energy) in the dual theory. The vacuum structure at zero temperature is studied in the soliton background and it illustrates the topological phase transition in the presence of instantons. Moreover, since the confinement/deconfinement phase transition could be holographically identified as the Hawking-Page transition in the bulk, we accordingly calculate the critical temperature of the deconfinement phase transition by collecting the bulk onshell action as the thermodynamical free energy. On the other hand, we evaluate the difference of the entanglement entropy in slab configuration by using the RT formula since the confinement may also be characterized by the entanglement entropy. Altogether we find the behavior of the critical temperature is in qualitative agreement with the behavior of the critical length determined by the entanglement entropy which implies the entanglement entropy could indeed be a character of the confinement in our setup and the D3-D(-1) system would be a remarkable approach to study the three-dimensional gauge theory.

description: While the advances in synchrotron light sources, together with the development of focusing optics and detectors, allow nanoscale ptychographic imaging of materials and biological specimens, the corresponding experiments can yield terabyte-scale large volumes of data that can impose a heavy burden on the computing platform. While Graphical Processing Units (GPUs) provide high performance for such large-scale ptychography datasets, a single GPU is typically insufficient for analysis and reconstruction. Several existing works have considered leveraging multiple GPUs to accelerate the ptychographic reconstruction. However, they utilize only Message Passing Interface (MPI) to handle the communications between GPUs. It poses inefficiency for the configuration that has multiple GPUs in a single node, especially while processing a single large projection, since it provides no optimizations to handle the heterogeneous GPU interconnections containing both low-speed links, e.g., PCIe, and high-speed links, e.g., NVLink. In this paper, we provide a multi-GPU implementation that can effectively solve large-scale ptychographic reconstruction problem with optimized performance on intra-node multi-GPU. We focus on the conventional maximum-likelihood reconstruction problem using conjugate-gradient (CG) for the solution and propose a novel hybrid parallelization model to address the performance bottlenecks in CG solver. Accordingly, we develop a tool called PtyGer (Ptychographic GPU(multiple)-based reconstruction), implementing our hybrid parallelization model design. The comprehensive evaluation verifies that PtyGer can fully preserve the original algorithm's accuracy while achieving outstanding intra-node GPU scalability.
Interval Timing: Modeling the break-run-break pattern using start/stop threshold-less drift-diffusion model

Publisher: name: arXiv

Subjects: subject: Neurons and Cognition (q-bio.NC)

description: Animal interval timing is often studied through the peak interval (PI) procedure. In this procedure, the animal is rewarded for the first response after a fixed delay from the stimulus onset, but on some trials, the stimulus remains and no reward is given. The common methods and models to analyse the response pattern describe it as break-run-break, a period of low rate response followed by rapid responding, followed by a low rate of response. The study of the pattern has found correlations between start, stop, and duration of the run period that hold across species and experiment. It is commonly assumed that in order to achieve the statistics with a pacemaker accumulator model it is necessary to have start and stop thresholds. In this paper we will develop a new model that varies response rate in relation to the likelihood of event occurrence, as opposed to a threshold, for changing the response rate. The new model reproduced the start and stop statistics that have been observed in 14 different PI experiments from 3 different papers. The developed model is also compared to the Time-adaptive Drift-diffusion Model (TDDM), the latest accumulator model subsuming the scalar expectancy theory (SET), on all 14 data-sets. The results show that it is unnecessary to have explicit start and stop thresholds or an internal equivalent to break-run-break states to reproduce the individual trials statistics and population behaviour and get the same break-run-break analysis results. The new model also produces more realistic individual trials compared to TDDM.

description: The FitzHugh-Rinzel system is able to describe some biophysical phenomena, such as bursting oscillations, and the study of its solutions can help to better understand several behaviours of the complex dynamics of biological systems. We express the solutions by means of an integral equation involving the fundamental solution $ H(x,t) $ related to a non linear integro-differential equation. Properties of $ H(x,t) $ allow us to obtain a priori estimates for solutions determined in the whole space, showing both the influence of the initial data and the source term.
A-type antiferromagnetic order and magnetic phase diagram of the trigonal Eu spin-7/2 triangular-lattice compound EuSn2As2

description: The trigonal compound EuSn2As2 was recently discovered to host Dirac surface states within the bulk band gap and orders antiferromagnetically below the Neel temperature TN = 24 K. Here the magnetic ground state of single-crystal EuSn2As2 and the evolution of its properties versus temperature T and applied magnetic field H are reported. Included are zero-field single-crystal neutron-diffraction measurements versus T, magnetization M(H,T), magnetic susceptibility chi(H,T) = M(T)/H, heat capacity Cp(H,T), and electrical resistivity rho(H,T) measurements. The neutron-diffraction and chi(T) measurements both indicate a collinear A-type antiferromagnetic (AFM) structure below TN =23.5(2) K, where the Eu{2+} spins S = 7/2 in a triangular ab-plane layer (hexagonal unit cell) are aligned ferromagnetically in the ab plane whereas the spins in adjacent Eu planes along the c axis are aligned antiferromagnetically. The chi(H{ab},T) and chi(H{c},T) data together indicate a smooth crossover between the collinear AFM alignment and an unknown magnetic structure at H ~ 0.15 T. Dynamic spin fluctuations up to 60 K are evident in the chi(T), Cp(T) and rho(H,T) measurements, a temperature that is more than twice TN. The rho(H,T) of the compound does not reflect a contribution of the topological state, but rather is consistent with a low-carrier-density metal with strong magnetic scattering. The magnetic phase diagrams for both H||c and H||ab in the H-T plane are constructed from the TN(H), chi(H,T), Cp(H,T), and rho(H,T) data.

The Cheapest Ticket Problem in Public Transport

Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: Route choice models in public transport have been discussed for a long time. The main factor why a passenger chooses a specific path is usually based on its length or travel time. However, also the ticket price that passengers have to pay may influence their decision since passengers prefer cheaper paths over more expensive ones. In this paper, we deal with the cheapest ticket problem which asks for a cheapest ticket to travel between a pair of stations. The complexity and the algorithmic approach to solve this problem depend crucially on the underlying fare structure, e.g., it is easy if the ticket prices are proportional to the distance traveled (as in distance tariff fare structures), but may become NP-complete in zone tariff fare structures. We hence discuss the cheapest ticket problem for different variations of distance- and zone-based fare structures. We start by modeling the respective fare structure mathematically, identify its main properties, and finally provide a polynomial algorithm, or prove NP-completeness of the cheapest ticket problem. We also provide general results on the combination of two fare structures, which is often observed in practice.

description: In this paper, we introduce a novel visual representation learning which relies on a handful of adaptively learned tokens, and which is applicable to both image and video understanding tasks. Instead of relying on hand-designed splitting strategies to obtain visual tokens and processing a large number of densely sampled patches for attention, our approach learns to mine important tokens in visual data. This results in efficiently and effectively finding a few important visual tokens and enables modeling of pairwise attention between such tokens, over a longer temporal horizon for videos, or the spatial content in images. Our experiments demonstrate strong performance on several challenging benchmarks for both image and video recognition tasks. Importantly, due to our tokens being adaptive, we accomplish competitive results at significantly reduced compute amount. We obtain comparable results to the state-of-the-arts on ImageNet while being computationally more efficient. We also confirm the effectiveness of the approach on multiple video datasets, including Kinetics-400, Kinetics-600, Charades, and AViD.

description: High-resolution satellite imagery has proven useful for a broad range of tasks, including measurement of global human population, local economic livelihoods, and biodiversity, among many others. Unfortunately, high-resolution imagery is both infrequently collected and expensive to purchase, making it hard to efficiently and effectively scale these downstream tasks over both time and space. We propose a new conditional pixel synthesis model that uses abundant, low-cost, low-resolution imagery to generate accurate high-resolution imagery at locations and times in which it is unavailable. We show that our model attains photo-realistic sample quality and outperforms competing baselines on a key downstream task -- object counting -- particularly in geographic locations where conditions on the ground are changing rapidly.

description: Physalis peruviana L. (Solanaceae) has been used in tropical and subtropical countries of the world as medicinal and fruit trees. In this study, a new withanolide named withaperuvin O (1) and seven known ones, including physalolactone B-3-O-β-D-glucopyranoside (2), withanolide J (3), physapruin A (4), physaperuvin G (5), withaperuvin (6), withaperuvin C (7) and 28-hydroxywithaperuvin C (8), were isolated from the whole plants of P. peruviana. Their structures were elucidated based on extensive spectroscopic analyses including NMR and HR-ESI-MS. The bioactivities of these compounds against lipopolysaccharide (LPS)-induced NO production in RAW264.7 cells and cytotoxicity against HepG2 were tested. Compound 3 showed strong anti-inflammatory activities with IC50 3.55 ± 0.12 µM (compared to positive control L-NMMA 7.72 ± 0.46 µM). Compounds 3 and 4 inhibited HepG2 cell line with the IC50 values of 2.01 ± 0.12 µM, 0.96 ± 0.05 µM, respectively (Ellipticine, 0.32 ± 0.02 µM). Our study indicated that compounds 3 and 4 could be new potential natural products for the development of anti-inflammatory and anti-cancer agents.
Non$-$zero $ θ_{13} $ and $ δ_{CP} $ phase with $ A_{4} $ Flavor Symmetry and Deviations to Tri$-$Bi$-$Maximal mixing via $ Z_{2} \times Z_{2}$ invariant perturbations in the Neutrino sector

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this work, a flavour theory of a neutrino mass model based on $ A_{4} $ symmetry is considered to explain the phenomenology of neutrino mixing. The spontaneous symmetry breaking of $ A_{4} $ symmetry in this model leads to tribimaximal mixing in the neutrino sector at a leading order. We consider the effect of $ Z_{2} \times Z_{2}$ invariant perturbations in neutrino sector and find the allowed region of correction terms in the perturbation matrix that is consistent with 3$ σ$ ranges of the experimental values of the mixing angles. We study the entanglement of this formalism on the other phenomenological observables, such as $ δ_{CP} $ phase, the neutrino oscillation probability $ P(ν_μ\rightarrow ν_{e} )$, the effective Majorana mass $ |m_{ee} |$ and $ |m^{eff}_{νe} |$. A $ Z_{2} \times Z_{2}$ invariant perturbations in this model is introduced in the neutrino sector which leads to testable predictions of $ θ_{13} $ and CP violation. By changing the magnitudes of perturbations in neutrino sector, one can generate viable values of $ δ_{CP} $ and neutrino oscillation parameters. Next we investigate the feasibility of charged lepton flavour violation in type-I seesaw models with leptonic flavour symmetries at high energy that leads to tribimaximal neutrino mixing. We consider an effective theory with an $A_{4} \times Z_{2} \times Z_{2} $ symmetry, which after spontaneous symmetry breaking at high scale which is much higher than the electroweak scale leads to charged lepton flavour violation processes once the heavy Majorana neutrino mass degeneracy is lifted either by renormalization group effects or by a soft breaking of the $ A_{4} $ symmetry. In this context the implications for charged lepton flavour violation processes like $ μ\rightarrow e γ$, $ τ\rightarrow e γ$, $ τ\rightarrow μγ$ are discussed.

description: Stratification of fluids can occur through either temperature or salinity variations. When temperature is varied, a stably stratified fluid is one in which cooler, denser fluid is lower than warmer fluid. If such a fluid is incident on an insulating, inclined surface, the cooler fluid will flow up that surface. This phenomenon is termed 'diffusion-driven flow'. This thesis extends the current understanding of diffusion-driven flow by considering a variety of problems that vary in three spatial dimensions. These problems are addressed with a combination of numerical solutions, and analytical solutions found using asymptotic techniques.

description: Measurement of angular distributions and energy spectra of $α$ and deuterons through breakup, transfer and incomplete fusion processes to dis-entangle their relative contributions and to investigate relative importance of breakup-fusion compared to transfer. Inclusive $α$ production cross-sections have been measured for $^6$Li + $^{51}$V system near Coulomb barrier energies. Theoretical calculations for estimation of various reaction channels contributing to $α$ production have been performed with finite range coupled reaction method using \textsc{FRESCO} code. The cross-sections from non-capture breakup (NCBU) ($α$ + \textit{d}) and 1\textit{n}, 1\textit{p}, and 1\textit{d} transfer channels, compound nuclear decay channel and incomplete fusion (ICF) leading to $α$ production were estimated to get the cumulative production cross-sections. Contributions from breakup, transfer and incomplete fusion channels could reproduce the integral direct $α$ production cross-sections and their angular distributions quite well. The direct $α$ production cross-sections are in agreement with other targets. The $α$ production cross-sections are higher compared to the deuteron production. Kinematic analysis of the energy spectra of $α$ particles and deuterons suggest that $α$ particle spectra is dominated by breakp-fusion and deuteron spectra have contribution of breakup and transfer reactions. A systematic study of direct $α$ production with various targets follow a universal behavior on average but noticeable differences are observed for different targets. A ratio of $α$ and deuteron yields for a wide mass range of targets shows a saturation above barrier and an increasing production of $α$ particles relative to deuteron around Coulomb barrier.

description: Urban areas are Earth’s fastest growing land use that impact hydrological and ecological systems and the surface energy balance. The identification and extraction of accurate spatial information relating to urban areas is essential for future sustainable city planning owing to its importance within global environmental change and human–environment interactions. However, monitoring urban expansion using medium resolution (30–250 m) imagery remains challenging due to the variety of surface materials that contribute to measured reflectance resulting in spectrally mixed pixels. This research integrates high spatial resolution orthophotos and Landsat imagery to identify differences across a range of diverse urban subsets within the rapidly expanding Perth Metropolitan Region (PMR), Western Australia. Results indicate that calibrating Landsat-derived subpixel land-cover estimates with correction values (calculated from spatially explicit comparisons of subpixel Landsat values to classified high-resolution data which accounts for over [under] estimations of Landsat) reduces moderate resolution urban area over (under) estimates by on an average 55.08% for the PMR. This approach can be applied to other urban areas globally through use of frequently available and/or low-cost high spatial resolution imagery (e.g. using Google Earth). This will improve urban growth estimations to help monitor and measure change whilst providing metrics to facilitate sustainable urban development targets within cities around the world.

description: Layer transfer offers enormous potential for the industrial implementation of 2D material technology platforms. However, the transfer method used must retain as-grown uniformity and cleanliness in the transferred films for the fabrication of 2D material-based. Additionally, the method used must be capable of large-area transfer to maintain wafer-scale fabrication standards. Here, a facile route to transfer centimeter-scale synthesized 2D TMDCs (3L MoS2, 1L WS2) onto various substrates such as sapphire, SiO2/Si, and flexible substrates (mica, polyimide) has been developed using a water-soluble layer (Na2S/Na2SO4) underneath the as-grown film. The developed transfer process represents a fast, clean, generic, and scalable technique to transfer 2D atomic layers. The key strategy used in this process includes the dissolution of Na2S/Na2SO4 layer due to the penetration of NaOH solution between the growth substrate and hydrophobic 2D TMDC film. As a proof-of-concept device, a broadband photodetector has been fabricated onto transferred 3L MoS2, which shows photoresponse behavior for a wide range of wavelength ranging from NIR to UV. The enhancement in photocurrent was found to be 100 times and 10 times to dark current in the UV and visible region, respectively. This work opens up the pathway towards flexible electronics and optoelectronics.
On the Performance Analysis of the Adversarial System Variant Approximation Method to Quantify Process Model Generalization

description: Process mining algorithms discover a process model from an event log. The resulting process model is supposed to describe all possible event sequences of the underlying system. Generalization is a process model quality dimension of interest. A generalization metric should quantify the extent to which a process model represents the observed event sequences contained in the event log and the unobserved event sequences of the system. Most of the available metrics in the literature cannot properly quantify the generalization of a process model. A recently published method [1] called Adversarial System Variant Approximation leverages Generative Adversarial Networks to approximate the underlying event sequence distribution of a system from an event log. While this method demonstrated performance gains over existing methods in measuring the generalization of process models, its experimental evaluations have been performed under ideal conditions. This paper experimentally investigates the performance of Adversarial System Variant Approximation under non-ideal conditions such as biased and limited event logs. Moreover, experiments are performed to investigate the originally proposed sampling hyperparameter value of the method on its performance to measure the generalization. The results confirm the need to raise awareness about the working conditions of the Adversarial System Variant Approximation method. The outcomes of this paper also serve to initiate future research directions. [1] Theis, Julian, and Houshang Darabi.

description: This article explores the need for Treaty-based local governance, raised to national prominence by the 2014 outrage against New Plymouth Mayor Andrew Judd, who advocated a Māori ward for 2016. The Treaty of Waitangi influenced the creation of Māori seats in Parliament in the nineteenth century, and a provision for Māori seats in local councils in 2001. There has been limited uptake of the latter and Māori remain significantly under-represented. Innovations in governing arrangements have allowed non-elected Māori to take up advisory roles and, in some cases, decision-making roles. We argue that these do not ensure fair and effective Māori representation. Ad hoc and unpredictable structures have failed to deliver fair and effective representation to all New Zealanders. There is a pressing need for a New Zealand constitutional debate – a conversation among Māori and non-Māori – to devise a governance model that addresses the Treaty of Waitangi as New Zealand’s founding document.

description: Seizure-related autonomic dysregulation occurs in epilepsy patients and may contribute to Sudden Unexpected Death in Epilepsy (SUDEP). We tested how different types of seizures affect baroreflex sensitivity (BRS). We hypothesized that BRS would be reduced after generalized tonic-clonic seizures (GTCS). Our results showed significant post-ictal autonomic dysregulation in patients with epilepsy following GTCS. Further, the loss of BRS following GTCS may indicate a generalized post-ictal brainstem dysfunction following seizures, and BRS measurements in GTCS may provide one quantifiable risk marker of SUDEP.
