description: AlphaFind is a web-based search engine that allows for structure-based search of the entire AFDB. Uniprot ID, PDB ID, or Gene Symbol is accepted as input – AlphaFind will return the most similar proteins found within AlphaFold DB, with an option to perform additional search to extend and refine the results. The search results are grouped by their source organism and displayed along with their TM-Score and RMSD measures (relative to the query protein). If the result proteins are experimentally found, we provide all associated PDB IDs. The 3D visualizations of the structural overlap of the proteins are provided using NGL Viewer, and the additional filters at the top of the results table can be used to find specific organisms or Uniprot IDs.

description: We present a combined study of the thermal expansion and the thermal conductivity of the perovskite series RCoO_3 with R = La, Nd, Pr and Eu. The well-known spin-state transition in LaCoO_3 is strongly affected by the exchange of the R ions due to their different ionic radii, i.e. chemical pressure. This can be monitored in detail by measurements of the thermal expansion, which is a highly sensitive probe for detecting spin-state transitions. The Co ions in the higher spin state act as additional scattering centers for phonons, therefore suppressing the phonon thermal conductivity. Based on the analysis of the interplay between spin-state transition and heat transport, we present a quantitative model of the thermal conductivity for the entire series. In PrCoO_3, an additional scattering effect is active at low temperatures. This effect arises from the crystal field splitting of the 4f multiplet, which allows for resonant scattering of phonons between the various 4f levels.

Identifying sample swaps in clinical and omics data pairs - A literature overview

Year: 2024

description: When data is collected, containing repeated measurements, multiple omics types and additional clinical data belonging to the same individual, accidental sample mix-ups can lead to reduced power and false positive results in downstream analyses.



A systematic literature research on PubMed followed by manual screening resulted in 19 relevant articles presenting methods to detect sample swaps. We analyzed these methods considering two main categories: 1) supported data types, 2) ability to correct mismatched samples. We further investigated constraints of these methods, such as the need for an especially small or large cohort.



We found that most methods (11/19) are able to detect possible mismatched samples in-between different data types, often based on comparing (inferred) genotypes. However, only two approaches aim to correct the identified mismatches within the given cohort. Furthermore, evaluation of clinical data is commonly not supported. Only two algorithms, Idéfix and Peddy, make use of clinical traits predicted from genetic information (e.g. sex, height, BMI, ancestry and relatedness), to estimate whether the clinical and genetic data is paired correctly. However, Idéfix’s automatic detection relies on sufficiently large cohorts (e.g. biobanks) and does not aim to correct sample swaps, while Peddy requires the user to manually examine the visualized comparisons.



The current lack of tools supporting clinical and multi-omics data, also correcting identified mismatches, points out the need for novel methods. An algorithm detecting and correcting sample mix-ups based on similarity scores between clinical traits and their predictions by machine learning models could be a viable option.
On the inconsistency between the black hole mass function inferred from M_bh-sigma and M_bh-L correlation

description: Black hole masses are tightly correlated with the stellar velocity dispersions of the bulges which surround them, and slightly less-well correlated with the bulge luminosity. It is common to use these correlations to estimate the expected abundance of massive black holes. This is usually done by starting from an observed distribution of velocity dispersions or luminosities and then changing variables. This procedure neglects the fact that there is intrinsic scatter in these black hole mass--observable correlations. Accounting for this scatter results in estimates of black hole abundances which are larger by almost an order of magnitude at masses >10^9 M_sun. Including this scatter is particularly important for models which seek to infer quasar lifetimes and duty cycles from the local black hole mass function. However, even when scatter has been accounted for, the M_bh-sigma relation predicts fewer massive black holes than does the M_bh-L relation. This is because the sigma-L relation in the black hole samples currently available is inconsistent with that in the SDSS sample from which the distributions of L or sigma are based: the black hole samples have smaller L for a given sigma, or larger sigma for a given L. The sigma-L relation in the black hole samples is similarly discrepant with that in other samples of nearby early-type galaxies. This suggests that current black hole samples are biased: if this is a selection rather than physical effect, then the M_bh-sigma and M_bh-L relations currently in the literature are also biased from their true values.

description: The Rindler spacetime describing a series of accelerating observers is Ricci flat, but it still has novel optical effects. In the case of WKB approximation, we derive the light geodesics in the Rindler frame based on the covariant wave equation and geodesic equations. Then, we use ABCD matrix optics method to explore the propagation characteristics of Rindler frame, thus link three different optical transformation scenes (geometry, gravity and vacuum refractive index) together. Moreover, the propagation characteristics of hollow beam in Rindler spacetime are described analytically. Those characteristics are quite different from the ones in the flat spacetime. Based on these calculations, we simply demonstrate the position uncertain relationship between the transverse beam size and the momentum, which surprisingly coincides with the derivation of quantization. We hope that we can provide one simple method to analyze the beam propagation in the accelerated frame.

Αρχικά έγινε ιστορική αναδρομή της πορείας της χρήσης των βασανιστηρίων και διατυπώθηκε ένας πρώιμος ορισμός των βασανιστηρίων. Στη συνέχεια αναλύθηκε ο κανόνας jus cogens περί απαγόρευσης των βασανιστηρίων στην έννομη τάξη της ΕΣΔΑ, του ΔΣΑΠΔ και της ΣΚΒ. Επιπλέον έγινε εκτενής ανάλυση του γεγονότος της τρομοκρατικής επίθεσης της 11ης Σεπτεμβρίου, οι ιστορικές συγκυρίες που οδήγησαν σε αυτό και οι πολιτικές του συνέπειες στις ΗΠΑ και δευτερευόντως σε παγκόσμιο επίπεδο. Δόθηκε δε ιδιαίτερη σημασία στο νομικό αντίκτυπο της επίθεσης στο πεδίο των ανθρωπίνων δικαιωμάτων. Έπειτα, αναλύθηκε η περίπτωση των ΗΠΑ, η προσέγγισή τους στα βασανιστήρια, ο ορισμός τους στην έννομη τάξη τους και πόσα επιτρέπει το Σύνταγμά τους να πράξουν. Αναλύθηκε ο τρόπος με τον οποίο χρησιμοποιήθηκε το γεγονός της 11ης Σεπτεμβρίου ως γενικότερη ρήτρα παρέκκλισης από τη νομιμότητα. Τέλος, επιχειρήθηκε η κλασική στάθμιση της αναλογικότητας και το αν και κατά πόσο χωρεί η εφαρμογή της στο πλαίσιο της απαγόρευσης των βασανιστηρίων και της απάνθρωπης και εξευτελιστικής μεταχείρισης.
description: The aim of the present thesis was the study of prohibition of torture in the framework of United Nations, especially after the September 11th attacks. Firstly, a retrospection of the usage of torture is attempted, with the addition of a premature definition of torture. Then, we analyzed the jus cogens rule of the prohibition of torture in the framework of ECHR, ICCPR and OHCHR. Furthermore, we analyzed extensively the September 11th attack, the historical circumstances that led to it and its political consequences in the USA and at global level. Particular attention was drawn towards the attacks’ legal impact in the field of human rights. We also examined USA’s approach towards torture, torture definition in USA’s domestic legal order and the American Constitution rules in regard to torture. We also examined the ways the September 11th attack was used as a general derogation clause. Finally, we attempted to apply the classic proportionality weighting and whether it can be applied in the framework of the prohibition of torture and cruel, inhuman and degrading treatment.

description: The Bardeen-Cooper-Schrieffer (BCS) functional has recently received renewed attention as a description of fermionic gases interacting with local pairwise interactions. We present here a rigorous analysis of the BCS functional for general pair interaction potentials. For both zero and positive temperature, we show that the existence of a non-trivial solution of the nonlinear BCS gap equation is equivalent to the existence of a negative eigenvalue of a certain linear operator. From this we conclude the existence of a critical temperature below which the BCS pairing wave function does not vanish identically. For attractive potentials, we prove that the critical temperature is non-zero and exponentially small in the strength of the potential.

Geology of the Snip Mine, and its relationship to the magmatic and deformational history of the Johnny Mountain area, northwestern British Columbia
Creators: name: Rhys, David A.
Publisher: name: University of British Columbia
Year: 2016

description: The Snip mine consists of an auriferous southwest-dipping shear vein system in a north-dipping Triassic greywacke-siltstone sequence altered with abundant vein let and pervasive biotite. The deposit, termed the Twin zone, is the largest of numerous shear veins in the mine workings. It contains just under 30 tonnes of gold. The Twin zone is composed of four ore types that are mineralogical end members of two distinctive styles of mineralisation. They are: (i) carbonate and (ii) chlorite-biotite ore consisting of laminated schistose veins of calcite, chlorite, biotite and pyrite, which display textures indicative of an origin, at least partially by, wall rock replacement; and (iii) dilatant quartz veins and (iv) dilatant pyrite-pyrrhotite sulphide veins. Alteration comprises pale calcite-K-feldspar-silica envelopes surrounding black biotite envelopes adjacent to the veins. A post-ore biotite-altered mafic dyke intrudes the zone. Geologic relations in the Snip mine indicate that the mineralised veins were emplaced progressively in a dynamic tectonic environment characterised by semi-brittle deformation. Numerous kinematic features in the zone record normally-directed simple shear parallel to a westerly plunging elongation lineation. Deformation was heterogeneous and confined mainly to the shear veins. Galena Pb-Pb isotopic signatures suggest an Early Jurassic age for the veins. Abundant shallow easterly-dipping quartz-calcite extension veins formed during a later, probably Tertiary, event. The Red Bluff porphyry, an elongate K-feldspar megacrystic plagioclase porphyritic quartz diorite to tonalite stock, intrudes the greywacke sequence 300-800 metres northeast of the Twin zone. Two successive, intense hydrothermal events are centred on the porphyry and are associated with subeconomic Au and Cu concentrations. These are: (i) early quartz-magnetite-sericite-K-feldspar-biotite (potassic)alteration associated with abundant quartz-magnetite-hematite veins, overprinted by (ii) sericite-pyrite-quartz (phyllic) alteration characterised by pyrite veining. Intrusion, semi-brittle deformation, and alteration and mineralisation within the large hydrothermal system of the Red Bluff porphyry were closely related spatially and temporally. A genetic relationship is supported by: similarities in structural fabrics and alteration histories in the Twin zone and the porphyry, alteration and metal zoning of vein systems distributed concentrically around the porphyry, and apparently concordant Early Jurassic zircon U-Pb age from the porphyry with galena Pb-Pb signatures from the Twin zone and surrounding vein systems. Two significant structurally-controlled Au deposits in the area, Inel and Stonehouse, have similar age, mineralogy, structure, alteration and spatial relationships to Early Jurassic intrusions. They represent contemporaneous, possibly genetically related, hydrothermal systems.

description: Spin-dependent coherent quantum transport through carbon nanotubes (CNT) is studied theoretically within a tight-binding model and the Green's function partitioning technique. End-contacted metal/nanotube/metal systems are modelled and next studied in the magnetic context, i.e. either with ferromagnetic electrodes or at external magnetic fields. The former case shows that quite a substantial giant magnetoresistance (GMR) effect occurs ($\pm 20%$) for disorder-free CNTs. Anderson-disorder averaged GMR, in turn, is positive and reduced down to several percent in the vicinity of the charge neutrality point. At parallel magnetic fields, characteristic Aharonov-Bohm-type oscillations are revealed with pronounced features due to a combined effect of: length-to-perimeter ratio, unintentional electrode-induced doping, Zeeman splitting, and energy-level broadening. In particular, a CNT is predicted to lose its ability to serve as a magneto-electrical switch when its length and perimeter become comparable. In case of perpendicular geometry, there are conductance oscillations approaching asymptotically the upper theoretical limit to the conductance, $4 e^2/h$. Moreover in the ballistic transport regime, initially the conductance increases only slightly with the magnetic field or remains nearly constant because spin up- and spin down-contributions to the total magnetoresistance partially compensate each other.

description: With safety being one of the primary motivations for developing automated vehicles (AVs), extensive field and simulation tests are being carried out to ensure AVs can operate safely on roadways. Since 2014, the California DMV has been collecting AV collision and disengagement reports, which are valuable data sources for studying AV crash patterns. In this study, crash sequence data extracted from California AV collision reports were used to investigate patterns and how they may be used to develop AV test scenarios. Employing sequence analysis, this study evaluated 168 AV crashes (with AV in automatic driving mode before disengagement or collision) from 2015 to 2019. Analysis of subsequences showed that the most representative pattern in AV crashes was (collision following AV stop) type. Analysis of event transition showed that disengagement, as an event in 24 percent of all studied AV crash sequences, had a transition probability of 68 percent to an immediate collision. Cluster analysis characterized AV crash sequences into seven groups with distinctive crash dynamic features. Cross-tabulation analysis showed that sequence groups were significantly associated with variables measuring crash outcomes and describing environmental conditions. Crash sequences are useful for developing AV test scenarios. Based on the findings, a scenario-based AV safety testing framework was proposed with sequence of events embedded as a core component.
The Maxwell field on the Schwarzschild spacetime: behaviour near spatial infinity

Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The behaviour of the Maxwell field near one of the spatial infinities of the Schwarzschild solution is analysed by means of the transport equations implied by the Maxwell equations on the cylinder at spatial infinity. Initial data for the Maxwell equations will be assumed to be expandable in terms of powers of a coordinate $ρ$ measuring the geodesic distance to spatial infinity (in the conformal picture) and such that the highest possible spherical harmonics at order $p$ are $2^p$-polar ones. It is shown that if the $2^p$-polar harmonics at order $p$ in the initial data satisfy a certain regularity condition then the solutions to the transport equations at orders $p$ and $p+1$ are completely regular at the critical sets where null infinity touches spatial infinity. On the other hand, the solutions to the transport equations of order $p+2$ contain, in general, logarithmic singularities at the critical sets. It is expected that the ideas and techniques developed in the analysis of this problem can be employed to discuss the more challenging case of the transport equations implied by the conformal Einstein equations, and thus provide a way of constructing a proof of a certain rigidity conjecture concerning the developments of conformally flat initial data sets.

description: Background and purpose — It is unclear what degree of malalignment of a fracture of the distal radius benefits from reduction. This study addressed the following questions: (1) What is the interobserver reliability of surgeons concerning the recommendation for a reduction for dorsally displaced distal radius fractures? (2) Do expert-based criteria for reduction improve reliability or not? Methods — We sent out 2 surveys to a group of international hand and fracture surgeons. On the first survey, 80 surgeons viewed radiographs of 95 dorsally displaced (0° to 25°) fractures of the distal radius. The second survey randomized 68 participants to either receive or not receive expert-based criteria for when to reduce a fracture and then viewed 20 radiographs of fractures with dorsal angulation between 5° and 15°. All participants needed to indicate whether they would advise a reduction or not. Results — In the 1st study, the interrater reliability of advising a reduction was fair (kappa 0.31). Multivariable linear regression analyses indicated that each additional degree of dorsal angulation increased the chance of recommending a reduction by 3%. In the 2nd study, reading criteria for reduction did not increase interobserver reliability for recommending a reduction. Interpretation — There is notable variation in recommendations for reduction that is not accounted for by surgeon or patient factors and is not diminished by exposure to expert criteria. Surgeons should be aware of their biases and develop strategies to inform patients and share the decision regarding whether to reduce a fracture of the distal radius.

description: Let $M$ be a closed manifold of Sasaki type. A polarization of $M$ is defined by a Reeb vector field, and for one such, we consider the set of all Sasakian metrics compatible with it. On this space, we study the functional given by the squared $L^2$-norm of the scalar curvature. We prove that its critical points, or canonical representatives of the polarization, are Sasakian metrics that are transversally extremal. We define a Sasaki-Futaki invariant of the polarization, and show that it obstructs the existence of constant scalar curvature representatives. For a fixed CR structure of Sasaki type, we define the Sasaki cone of structures compatible with this underlying CR structure, and prove that the set of polarizations in it that admit a canonical representative is open.

description: We use deep high resolution \textit{HST/ACS} imaging of two fields in the core of the Coma cluster to investigate the occurrence of nuclear star clusters (NSCs) in quiescent dwarf galaxies as faint as $M_{I} = -10$ mag. We employ a hierarchical Bayesian logistic regression framework to model the faint end of the nucleation fraction ($f_{n}$) as a function of both galaxy luminosity and environment. We find that $f_n$ is remarkably high in Coma: at $M_{I} \approx -13$ mag half of the cluster dwarfs still host prominent NSCs. Comparison with dwarf systems in nearby clusters and groups shows that, within the uncertainties, the rate at which the probability of nucleation varies with galaxy luminosity is nearly universal. On the other hand, the fraction of nucleated galaxies at fixed luminosity does exhibit an environmental dependence. More massive environments feature higher nucleation fractions and fainter values of the half-nucleation luminosity, which roughly scales with host halo virial mass as $L_{I,f_{n50}} \propto \mathcal{M}_{200}^{-0.2}$. Our results reinforce the role of galaxy luminosity/mass as a major driver of the efficiency of NSC formation and also indicate a clear secondary dependence on the environment, hence paving the way to more refined theoretical models.

description: Background and purpose — Uncemented stems are gradually replacing cemented stems in hip revision surgery. We compared the risk of re-revision between uncemented and cemented revision stems and assessed whether the different fixation methods are used in similar femoral bone defects. Patients and methods — 867 patients operated on with uncemented or cemented stems in first-time hip revision surgery due to aseptic loosening performed 2006–2016 were identified in the Swedish Hip Arthroplasty Register. Preoperative femoral bone defect size was assessed on radiographs of all patients. Cox regression models were fitted to estimate the adjusted risk of re-revision during different postoperative time periods. Re-revision of any component for any reason, and stem re-revision, as well as risk of cause-specific re-revision was estimated. Results — Most patients in both fixation groups had Paprosky class IIIA femoral bone defects prior to surgery, but there were more severe bone defects in the cemented group. The adjusted risk of re-revision of any component for any reason was higher in patients with uncemented compared with those with cemented revision stems during the first 3 years after index surgery (hazard ratio [HR] 4, 95% confidence interval [CI] 2–9). From the 4th year onward, the risk of re-revision of any component for any reason was similar (HR 0.5, CI 0.2–1.4). Uncemented revision stems conferred a higher risk of dislocation compared with cemented stems (HR 5, CI 1.2–23) during the first 3 years. Interpretation — Although not predominantly used in more complex femoral defects, uncemented revision stem fixation confers a slightly higher risk of re-revision during the first years, but this risk is attenuated after longer follow-up.

description: We study the problem of aligning two sets of 3D geometric primitives given known correspondences. Our first contribution is to show that this primitive alignment framework unifies five perception problems including point cloud registration, primitive (mesh) registration, category-level 3D registration, absolution pose estimation (APE), and category-level APE. Our second contribution is to propose DynAMical Pose estimation (DAMP), the first general and practical algorithm to solve primitive alignment problem by simulating rigid body dynamics arising from virtual springs and damping, where the springs span the shortest distances between corresponding primitives. We evaluate DAMP in simulated and real datasets across all five problems, and demonstrate (i) DAMP always converges to the globally optimal solution in the first three problems with 3D-3D correspondences; (ii) although DAMP sometimes converges to suboptimal solutions in the last two problems with 2D-3D correspondences, using a scheme for escaping local minima, DAMP always succeeds. Our third contribution is to demystify the surprising empirical performance of DAMP and formally prove a global convergence result in the case of point cloud registration by charactering local stability of the equilibrium points of the underlying dynamical system.

description: While it is intuitive that conflict and poor social cohesion have great economic and social costs, it has been difficult to quantify such costs until recently. This paper estimates the economic benefits of greater social cohesion as well as the correlation between social cohesion and other aspects of development, using a set of social institutional measures covering over 200 indicators from 25 different data sources. The paper also uses these measures to identify case studies in building social cohesion, to which political and social leaders might refer when considering how to tackle social tensions.
Observational Constraints on Trojans of Transiting Extrasolar Planets

description: Theoretical studies predict that Trojans are likely a frequent byproduct of planet formation and evolution. We present a novel method of detecting Trojan companions to transiting extrasolar planets which involves comparing the time of central eclipse with the time of the stellar reflex velocity null. We demonstrate that this method offers the potential to detect terrestrial-mass Trojans using existing ground-based observatories. This method rules out Trojan companions to HD 209458b and HD 149026b more massive than ~13 Earth masses and \~25 Earth masses at a 99.9% confidence level. Such a Trojan would be dynamically stable, would not yet have been detected by photometric or spectroscopic monitoring, and would be unrecognizable from radial velocity observations alone. We outline the future prospects for this method, and show that the detection of a "Hot Trojan" of any mass would place a significant constraint on theories of orbital migration.

description: Background and purpose — The increasing prevalence of total hip arthroplasty (THA) and total knee arthroplasty (TKA) within the growing elderly population is translating into a larger number of patients with neuromuscular conditions such as myasthenia gravis (MG) receiving arthroplasty. We compared systemic and joint complications following a THA or TKA between patients with MG and patients without MG. Patients and methods — Patient records were queried from PearlDiver (Pearl Diver Inc, Fort Wayne, IN, USA), an administrative claims database, using ICD-9/ICD-10 and Current Procedural Terminology codes. In-hospital and 90-day post-discharge rates of systemic and joint complications were compared between the 2 cohorts. Results — 372 patients with MG and 249,428 patients without MG who received a THA or TKA were included in the study. At 90 days post-discharge, MG patients exhibited exhibited between 1.6 and 15% higher rates of systemic complications, including cerebrovascular event, pneumonia, respiratory failure, sepsis, myocardial infarction, acute renal failure, anemia, and deep vein thrombosis (all p < 0.001). The same results were also found during the in-hospital time period. 90-day incidence of aseptic loosening was the only joint complication with significantly increased odds risk for the MG cohort (OR 5; 95% CI 2–12). Interpretation — Patients with MG exhibited significantly higher risk for multiple systemic complications during the index hospital stay and in the acute post-discharge setting.

description: BGGSe is a newly developed nonlinear material that is attractive for ultrabroad frequency mixing and ultrashort pulse generation due to its comparably low dispersion and high damage threshold.In a first experiment, we show that a long crystal length of 2.6 mm yields a pulse energy of 21 pJ at 100 MHz with a spectral bandwidth covering 5.8 to 8.5 microns. The electric field of the carrier-envelope-phase stable pulse is directly measured with electro-optical sampling and reveals a pulse duration of 91 fs, which corresponds to sub-four optical cycles, thus confirming some of the prospects of the material for ultrashort pulse generation and mid-infrared spectroscopy.
Axion-Dilaton Domain Walls and Fake Supergravity

description: Dynamical systems methods are used to investigate domain-wall solutions of a two-parameter family of models in which gravity is coupled to an axion, and to a dilaton with an exponential potential of either sign. A complete global analysis is presented for (i) constant axion and (ii) flat walls, including a study of bifurcations and a new exact domain-wall solution with non-constant axion. We reconsider `fake supergravity' issues in light of these results. We show, by example, how domain walls determine multi-valued superpotentials that branch at stationary points that are not stationary points of the potential, and we apply this result to potentials with anti-de Sitter vacua. We also show by example that `adapted' truncation to a single-scalar model is sometimes inconsistent, and we propose a `generalized' fake supergravity formalism that applies in some such cases.

Hospital variation in the risk of infection after hip fracture surgery: a population-based cohort study including 29,598 patients from 2012–2017

description: Background and purpose — Understanding the key drivers of hospital variation in postoperative infections after hip fracture surgery is important for directing quality improvements. Therefore, we investigated variation in the risk of any infection, and subgroups of infections including pneumonia and sepsis after hip fracture surgery. Methods — In this nationwide population-based cohort study, all Danish patients aged ≥ 65 undergoing surgery for an incident hip fracture from 2012 to 2017 were included. Risk of postoperative infections, based on data from hospital registration (hospital-treated infections) and antibiotic dispensing (community-treated infections), were calculated using multilevel Poisson regression analysis. Hospital variation was evaluated by intra-class coefficient (ICC) and median risk ratio (MRR). Results — The risk of hospital-treated infection was 15%. The risk of community-treated infection was 24%. The adjusted risk varied between hospitals from 7.8–25% for hospital-treated infection and 16–34% for community-treated infection. The ICC indicated that 19% of the adjusted variance was due to hospital level for hospital-treated infection. The ICC for community-treated infections was 13%. The MRR showed a 2-fold increased risk for the average patient acquiring a hospital-treated infection at the highest risk hospital compared with the lowest risk hospital. For community-treated infection, the MRR was 1.4. Interpretation — Our results suggest that 20% of infections could be reduced by applying the top performing hospitals’ approach. Nearly a 5th of the variation was at the hospital level. This suggests a more standardized approach to avoid postoperative infection after hip fracture surgery. Hip fracture is a leading cause of hospital admission among the elderly. The 30-day mortality following hip fracture surgery has been approximately 10% during the last few years in Denmark (Pedersen et al. 2017). Higher mortality after hip fracture has been associated with a range of hospital factors (Kristensen et al. 2016, Sheehan et al. 2016) and patient factors in observational studies (Roche et al. 2005). Furthermore, variation in 30-day mortality after hip fracture surgery has been observed between Danish hospitals, but not fully explained (Kristensen et al. 2019).

description: Abstract

Culture and traditions have always remained relevant aspects of human existence and world heritage. They distinguish a group of people from other human societies. Unfortunately, colonisation led to the erosion of several valuable aspects of African cultures and traditions. But in post genocide Rwanda, the need to ensure justice, as a precursor to reconciliation and sustainable peace in the country and the lacuna created by the dearth of western oriented judicial officers encouraged the resuscitation of traditional judicial system called Gacaca. This research   discovered that even though Gacaca Court system had its drawbacks, it still succeeded in realizing the objectives of fostering reconciliation and the country which was once an albatross of ethnic cleansing later became a beacon of peace, unity and development in Africa. The research recommended that African leaders should exhume, polish and preserve the valuable aspects of their culture which can facilitate their development.

description: In this paper, we present in-depth transfer matrix analyses of the Anderson transition in three non-Hermitian (NH) systems, NH Anderson, U(1) and Peierls models, that belong to NH class AI$^{\dagger}$ or NH class A. We first argue a general validity of the transfer matrix analysis, and clarify the symmetry properties of the Lyapunov exponents, scattering ($S$) matrix and two-terminal conductance in these NH models. The unitarity of the $S$ matrix is violated in NH systems, where the two-terminal conductance can take arbitrarily large values. Nonetheless, we show that the transposition symmetry of a Hamiltonian leads to the symmetric nature of the $S$ matrix as well as the reciprocal symmetries of the Lyapunov exponents and conductance in certain ways in these NH models. Finite size scaling data are fitted by polynomial functions, from which we determine the critical exponent $ν$ at different single-particle energies and system parameters of the NH models. We conclude that the critical exponents of the NH class AI$^{\dagger}$ and the NH class A are $ν=1.19 \pm 0.01$ and $ν=1.00 \pm 0.04$, respectively. In the NH models, a distribution of the two-terminal conductance is not Gaussian. Instead, it contains small fractions of huge conductance values, which come from rare-event states with huge transmissions amplified by on-site NH disorders. Nonetheless, a geometric mean of the conductance enables the finite-size scaling analysis. We show that the critical exponents obtained from the conductance analysis are consistent with those from the localization length in these three NH models.
