description: The aim was to evaluate the effect of locally administered insulin-like growth factor (IGF I) on functional recovery of peripheral nerve in diabetic rats. Sixty male healthy white Wistar rats were divided into four experimental groups (n = 15), randomly: In transected group (TC), left sciatic nerve was transected and stumps were fixed in the adjacent muscle. In treatment group defect was bridged using a silicone conduit (SIL/IGF) and filled with 10 µL IGF I (100 ng/kg). In silicone graft group (SIL), the graft was filled with phosphate-buffered saline alone. In sham-operated group (SHAM), sciatic nerve was exposed and manipulated. Each group was subdivided into three subgroups of five animals each and regenerated nerve fibers were studied 4, 8 and 12 weeks after surgery. Behavioral testing, sciatic nerve functional study, gastrocnemius muscle mass and morphometric indices confirmed faster recovery of regenerated axons in SIL/IGF than in SIL group (p < 0.05). In immunohistochemistry, location of reactions to S-100 in SIL/IGF was clearly more positive than that in SIL group. When loaded in a silicone graft, IGF I accelerated and improved functional recovery and morphometric indices of sciatic nerve in diabetic rats.

description: Eosinophilic enteritis is a rare disorder presenting mostly with diarrhea, malabsorption, abdominal pain, weight loss and hypersensitivity. Surgical manifestation of eosinophilic gastrointestinal disorders depends on the site and extent of involvement. In our case series of four patients two of them had ileocaecal masses with recurrent subacute intestinal obstruction with past history of intake of anti-tubercular drugs for 9 months. On histopathological examination both of them proved to have eosinophilic enterocolitis. Thus it is a clinical dilemma to differentiate between these two conditions. The other two patients presented as acute abdomen with perforation and intusseption. All four patients were treated surgically. Post operatively they recovered well with no symptoms on one year follow up. In Indian set up tuberculosis being rampant there may be under reporting or wrongly diagnosed cases of eosinophilic enteritis. Thus a strong clinical suspicion and awareness of this clinical entity is essential among surgical community.

description: Artemisinin resistance constitutes a major threat to the continued success of control programs for malaria. With alternative antimalarial drugs not yet available, improving our understanding of how artemisinin-based drugs act and how resistance manifests is essential to enable optimisation of dosing regimens in order to prolong the lifespan of current first-line treatment options. Here, through introduction of a novel model of the dynamics of the parasites' response to drug, we explore how artemisinin-based therapies may be adjusted to maintain efficacy and how artemisinin resistance may manifest and be overcome. We introduce a dynamic mathematical model, extending on the traditional pharmacokinetic-pharmacodynamic framework, to capture the time-dependent development of a stress response in parasites. We fit the model to in vitro data and establish that the parasites' stress response explains the recently identified complex interplay between drug concentration, exposure time and parasite viability. Our model demonstrates that the previously reported hypersensitivity of early ring stage parasites of the 3D7 strain to dihydroartemisinin (DHA) is primarily due to the rapid development of stress, rather than any change in the maximum achievable killing rate. Of direct clinical relevance, we demonstrate that the complex temporal features of artemisinin action observed in vitro have a significant impact on predictions of in vivo parasite clearance using PK-PD models. Given the important role that such models play in the design and evaluation of clinical trials for alternative drug dosing regimens, our model contributes an enhanced predictive platform for the continued efforts to minimise the burden of malaria.

description: ABSTRACT: Nanowire (NW)-based anodes for Li-ion batteries (LIBs) have been under investigation for more than a decade, with their unique one-dimensional (1D) morphologies and ability to transform into interconnected active material networks offering potential for enhanced cycling stability with high capacity. This is particularly true for silicon (Si)-based anodes, where issues related to large volumetric expansion can be partially mitigated and the cycle life can be enhanced. In this Perspective, we highlight the trajectory of Si NWs from a model system to practical Li-ion battery anode material and future prospects for extension to beyond Li-ion batteries. The study examines key research areas related to Si NW-based anodes, including state-of-the-art (SoA) characterization approaches followed by practical anode design considerations, including NW composite anode formation and upscaling/full-cell considerations. An outlook on the practical prospects of NW-based anodes and some future directions for study are detailed.

description: Here, we investigate spin Hall angle of Pt in Ni80Fe20/Pt bilayer system by using a broadband spin pumping and inverse spin Hall effect measurement. An out-of-plane excitation geometry with application of external magnetic field perpendicular to the charge current direction is utilized in order to suppress unwanted galvanomagnetic effects. Magnetization precession angle on ferromagnetic resonance for wide excitation frequency range (4-14 GHz) is estimated from the rectification voltage of anisotropic magnetoresistance (AMR) and a conventional method of using microwave power in a coplanar waveguide. A marked difference in the precession angle profiles for the different methods is observed, resulting in the large variation in estimated values of spin current density at Ni80Fe20/Pt interface. The frequency dependence of the spin current density estimated using AMR effect is found to be similar to that of the inverse spin Hall voltage. We obtain the frequency-invariant spin Hall angle of 0.067.

description: The three-sphere swimmer by Najafi and Golestanian is composed of three spheres connected by two arms. The case in which the swimmer can control the lengths of the two arms has been studied in detail. Here we study a variation of the model in which the swimmer's arms are constructed according to Hill's model of muscular contraction. The swimmer is able to control the tension developed in the active components of the arms. The two shape parameters and the tensions acting on the two arms are then obtained by solving a system of ordinary differential equations. We study the qualitative properties of the solutions, compute analytically their leading order approximation and compare them with numerical simulations. We also formulate and solve some optimisation problems, aimed at finding the actuation strategies maximising performance, for various performance measures. Finally, we discuss the structure of the governing equations of our microswimmers from the point of view of control theory. We show that our systems are control affine systems with drift.

description: We consider the parallaxes of sixteen cataclysmic variables and related objects that are included in the TGAS catalogue, which is part of the Gaia first data release, and compare these with previous parallax measurements. The parallax of the dwarf nova SS Cyg is consistent with the parallax determination made using the VLBI, but with only one of the analyses of the HST Fine Guidance Sensor (FGS) observations of this system. In contrast, the Gaia parallaxes of V603 Aql and RR Pic are broadly consistent, but less precise than the HST/FGS measurements. The Gaia parallaxes of IX Vel, V3885 Sgr, and AE Aqr are consistent with, but much more accurate than the Hipparcos measurements. We take the derived Gaia distances and find that absolute magnitudes of outbursting systems show a weak correlation with orbital period. For systems with measured X-ray fluxes we find that the X-ray luminosity is a clear indicator of whether the accretion disc is in the hot and ionised or cool and neutral state. We also find evidence for the X-ray emission of both low and high state discs correlating with orbital period, and hence the long-term average accretion rate. The inferred mass accretion rates for the nova-like variables and dwarf novae are compared with the critical mass accretion rate predicted by the Disk Instability Model. While we find agreement to be good for most systems there appears to be some uncertainty in the system parameters of SS Cyg. Our results illustrate how future Gaia data releases will be an extremely valuable resource in mapping the evolution of cataclysmic variables.

description: Mesoporous silica particles of MCM-41 type were synthesized by sol-gel method from tetraethyl orthosilicate (TEOS) in 2-methoxyethanol and deionized water mixture in base conditions at room temperature. Ammonia or sodium hydroxides were used as catalysts and cetyl-trimethylammonium bromide (CTAB) and n-dodecyl-trimethylammonium bromide (DTAB) as structure directing agents. The porosities and the ordered structure have been analyzed using transmission and scanning electron microscopy, small angle neutron and X-ray diffraction, nitrogen adsorption, thermal analysis and FTIR spectroscopy. The samples consist of spherical particles of sub-micrometer size, with radially arranged pores. The comparison of the effect of the different surfactants and catalysts shows that by varying the surfactant type and their proportion, the pore sizes can be controlled. As compared to the commonly used ammonia catalyst, the use of NaOH as catalyst results in a much smaller porosity of the as-prepared materials. These materials are not resisting to the heat treatment at 700 C used for the template removal, and the ordered porous structure is completely lost.

description: We combine star formation along the `main sequence', quiescence, and clustering and merging to produce an empirical model for the evolution of individual galaxies. Main sequence star formation alone would significantly steepen the stellar mass function towards low redshift, in sharp conflict with observation. However, a combination of star formation and merging produces a consistent result for correct choice of the merger rate function. As a result, we are motivated to propose a model in which hierarchical merging is disconnected from environmentally-independent star formation. This model can be tested via correlation functions and would produce new constraints on clustering and merging.

description: Combined duodenal atresia and pure esophageal atresia is a rare combination which has been reported only 13 times previously in the literature. Although this pair of congenital anomalies is amenable to current treatment strategies, it is often associated with additional defects which lead to the baby’s demise. We present a newborn prenatally diagnosed with trisomy 21, duodenal atresia and an AV canal defect. Postnatally, these diagnoses were confirmed, and the baby was also found to have pure esophageal atresia. Following a successful, staged repair of his duodenal atresia and pure esophageal atresia, the baby developed severe tracheobronchomalacia. At that point, the parents decided to withdraw care rather than embark on airway stent placement followed by cardiac surgery. This report highlights two of the most challenging aspects of pediatric surgery: 1) severe newborn anomalies requiring sound planning strategies and technical expertise and 2) an intimate relationship with the parents, so that the care can be individualized for the wishes of the family.

description: Omphalomesenteric duct remnants are a rare cause of abdominal pain, especially in the adult. Their diagnosis is not straightforward. We report the case of a healthy 25-year-old male presenting with chronic, intermittent abdominal pain over 1 month with no previous abdominal surgeries. Extensive investigations including computed tomography (CT) scan and colonoscopy were non-contributory. Thus a diagnostic laparoscopy was performed, which revealed a fibrous band originating from the anterior abdominal wall at the umbilicus and terminating behind the mid-transverse colon, with cecum and small bowel tethered to it, as well as signs of chronic inflammation in this area. Excision of the band as well as an appendectomy were performed. Histopathology confirmed the specimen to be an omphalomesenteric (vitelline) duct remnant, and also revealed an incidental small carcinoid tumour in the appendix. This case report highlights that undiagnosed abdominal pain with negative investigations needs to be treated with caution to not miss a broader range of diagnoses and that diagnostic laparoscopy is a useful tool. Omphalomesenteric duct remnant is a rare cause of chronic abdominal pain and intermittent obstruction in an adult.

description: The Einstein equations describing the black-brane dynamics both in Minkowski and AdS background were recently recast in the form of coupled diffusion equations in the large-$D$(imension) limit. Using such results in the literature, we formulate a higher-order perturbation theory of black branes in time domain and present the general form of solutions for arbitrary initial conditions. For illustrative purposes, the solutions up to the first or second order are explicitly written down for several kind of initial conditions, such as a Gaussian wave packet, shock wave, and rather general superposed sinusoidal waves. These could be the first examples describing the non-trivial evolution of black-brane horizons in time domain. In particular, we learn some interesting aspects of black-brane dynamics such as the Gregory-Laflamme (GL) instability and non-equilibrium steady state (NESS). The formalism presented here would be applicable to the analysis of various black branes and their holographically dual field theories.

description: Das 21. Jahrhundert ist geprägt von multiplen Krisen wie beispielsweise der Coronapandemie oder den immer spürbareren Auswirkungen der Klimakatastrophe. Um den sich hieraus ergebenden Herausforderungen erfolgreich zu begegnen, sind (natur-)wissenschaftliche Erkenntnisse entscheidend, wie zum Beispiel die Entwicklung der Impfstoffe gegen das Coronavirus gezeigt hat. Um Maßnahmen auf Basis wissenschaftlicher Erkenntnisse umzusetzen, bedarf es jedoch eines gewissen Vertrauens der Bevölkerung in die Wissenschaft und Forschung (z. B. Algan et al., 2021; van der Bles et al., 2020). Nach Daten des Wissenschaftsbarometers 2022 (Wissenschaft im Dialog, 2022) vertrauen 62 % der Befragten der Wissenschaft voll und ganz. Dieser Wert ist seit ca. 2020 stabil. Allerdings zeigen die Daten des Wissenschaftsbarometers auch, dass dieser Wert stark vom formalen Bildungsniveau abhängt: Je niedriger das formale Bildungsniveau, desto niedriger das Vertrauen in die Wissenschaft. Darüber hinaus zeigen die Daten, dass ca. 10 % der Befragten angeben, der Wissenschaft zu misstrauen. Diese Zahlen spiegeln sich in gesellschaftlichen Phänomenen wie der Querdenkerbewegung oder den Klimaleugnenden wider. Zusammenfassen lassen sich diese und weitere Fälle von Wissenschaftsleugnung und der Verbreitung von Verschwörungstheorien unter dem Begriff Science Denial. Science Denial beschreibt dabei Denkmuster von Personen, die sich auch in wissenschaftlichen Fragen von Überzeugungen anstatt von Evidenz leiten lassen und wissenschaftliche Erkenntnisse, die ihren Interessen entgegenstehen oder mit denen sie sich unwohl fühlen (z. B. die Abstammung des Menschen vom Affen oder drohende Wohlstandsverluste durch die Klimakatastrophe), ignorieren (vgl. Sinatra & Hofer, 2021). Vor diesem Hintergrund leitet sich aus dem Bildungsauftrag des naturwissenschaftlichen Unterrichts die Herausforderung ab, dem Phänomen Science Denial entgegen zu wirken. Um angehende Lehrkräfte in den naturwissenschaftlichen Fächern hierzu zu befähigen, wurde ein Seminarkonzept entwickelt und erprobt, welches im Folgenden vorgestellt wird.

description: This is the second paper in our series about the search for multiple populations in Magellanic Cloud star clusters using the Hubble Space Telescope. Here we report the detection of multiple stellar populations in the colour-magnitude diagrams of the intermediate-age clusters Lindsay 1, NGC 416 and NGC 339. With ages between 6.0 and 7.5 Gyr, these clusters are the youngest ones in which chemical abundance spreads have been detected so far. This confirms that the appearance of multiple populations is not restricted to only ancient globular clusters, but may also be a common feature in clusters as young as 6 Gyr. Our results are in agreement with a recent spectroscopic study of Lindsay 1. We found that the fraction of enriched stars in NGC 416 is ~45% whereas it is ~25% in NGC 339 and ~36% in Lindsay 1. Similar to NGC 121, these fractions are lower than the average value for globular clusters in the Milky Way.

description: In this letter we study the mean sizes of Halpha clumps in turbulent disk galaxies relative to kinematics, gas fractions, and Toomre Q. We use 100~pc resolution HST images, IFU kinematics, and gas fractions of a sample of rare, nearby turbulent disks with properties closely matched to z~1.5-2 main-sequence galaxies (the DYNAMO sample). We find linear correlations of normalized mean clump sizes with both the gas fraction and the velocity dispersion-to-rotation velocity ratio of the host galaxy. We show that these correlations are consistent with predictions derived from a model of instabilities in a self-gravitating disk (the so-called "violent disk instability model"). We also observe, using a two-fluid model for Q, a correlation between the size of clumps and self-gravity driven unstable regions. These results are most consistent with the hypothesis that massive star forming clumps in turbulent disks are the result of instabilities in self-gravitating gas-rich disks, and therefore provide a direct connection between resolved clump sizes and this in situ mechanism.

The Dark Matter Quantum Field Rebirth Model
Creators: name: Hubbuck, Robert Michael
Publisher: name: Zenodo
Year: 2025

description: This paper proposes a novel model of cosmic evolution, wherein Dark Matter operates as an active agent of cosmic recycling through quantum field interactions. In this model, supermassive black holes at galactic centers digest decayed matter at a quantum scale, transferring processed energy and information into the surrounding Dark Matter field. This enriched quantum substrate subsequently seeds the formation of new cosmic structures. We argue that galaxies themselves, through their birth, evolution, death, and rebirth, represent the true multiverse — an internal multiverse embedded within a single, eternal universe. This model unites cosmological processes with quantum field theory, offering a coherent vision of a living, self-renewing cosmos and addresses key challenges posed by the heat death scenario and external multiverse theories.

description: We consider resonances for fourth order differential operators on the half-line with compactly supported coefficients. We determine asymptotics of a counting function of resonances in complex discs at large radius, describe the forbidden domain for resonances and obtain trace formulas in terms of resonances. We apply these results to the Euler-Bernoulli operator on the half-line. The coefficients of this operator are positive and constants outside a finite interval. We show that this operator does not have any eigenvalues and resonances iff its coefficients are constants on the whole half-line.

description: Der Klimawandel, das Artensterben oder die Umweltverschmutzung – es gibt zahlreiche großen Themen, die unsere Gesellschaft vor Herausforderungen stellen. Die Begegnung mit globalen Herausforderungen führt zu komplexen Fragestellungen, für deren Erarbeitung neben umfassenden naturwissenschaftlichen Kenntnissen auch der Einbezug von gesellschaftlich geprägten Werten und Normen erforderlich sind (Sadler, 2004). Diese zumeist kontrovers diskutierten Fragestellungen werden in der Literatur als Socio-Scientific issues (SSI) bezeichnet, die sowohl naturwissenschaftliche Bezüge als auch gesellschaftliche Relevanz aufweisen sollten (Sadler, 2011). Die Bearbeitung von SSI im Schulkontext ermöglicht es, naturwissenschaftliche Inhalte für Lernende greifbar zu machen und einen hohen Realitätsbezug herzustellen. Doch die Integration von SSI in den naturwissenschaftlichen Unterricht kann Lehrkräfte vor Herausforderungen stellen (z. B. Dunlop & Veneu, 2019; Levinson, 2004). Eine zentrale Herausforderung besteht dabei darin, dass es an ausreichender Unterstützung beispielsweise durch die Kollaboration mit Kolleginnen und Kollegen aus anderen Fachbereichen mangelt (Garrecht et al., 2022; Pedersen & Totten, 2001). Gerade diese Zusammenarbeit zwischen unterschiedlichen Fachbereichen kann es aber möglich machen, Lernenden eine umfassende und realistische Bearbeitung von SSI zu ermöglichen. Die Zusammenarbeit zwischen Lehrkräften sollte dabei bereits im Laufe des Lehramtsstudiums angebahnt werden (siehe z. B. Seremet et al., 2021). Eine zweite zentrale Herausforderung für die Implementation von SSI im Unterricht besteht darin, dass es geeigneter Materialien bedarf, die der Komplexität des Themas gerecht werden. Hierzu bietet sich der Einsatz von digitalen Lernprodukten wie Erklärvideos und Podcasts an, die die Komplexität der Inhalte auf einer für die Lernenden ansprechenden Weise darstellen können (z. B. Cébrian-Robles et al., 2021). Im Rahmen des Beitrags wird daher ein Seminarkonzept vorgestellt, das angehende Lehrkräfte der Naturwissenschaften auf eine interdisziplinäre Vernetzung verschiedener Fachbereiche zur Entwicklung von digitalen Lernprodukten im Kontext von SSI vorbereiten soll. Die Struktur und der Ablauf des Kurses, die ersten entstandenen Lernprodukte sowie die gesammelten Ergebnisse aus der Pilotierung im Sommersemester 2022 werden im Beitrag vorgestellt.

description: We study the Dirac equation in a spacetime that represents the nonlinear superposition of the Schwarzchild solution to an external, stationary electromagnetic Berttoti-Robinson solution. We separate the Dirac equation into radial and angular equations using Newman--Penrose formalism. We obtain exact analytical solutions of the angular equations. We manage to obtain the radial wave equations with effective potentials. Finally, we study the potentials by plotting them as a function of radial distance and examine the effect of the twisting parameter and the frequencies on the potentials.

description: Cross-linked poly-1-(4-vinylbenzyl)imidazole and cross-linked poly-4-vinylpyridine have been prepared from respective vinyl monomers using different quantities of divinylbenzene as a cross-linker by radical polymerization. The polymeric bases were characterized by FT-IR, TGA, field emission-scanning electron microscopy (FE-SEM), and Brunauer-Emmett-Teller (BET) surface area analysis. Their swelling behavior was also studied. They were used as base catalysts for 1,3-dipolar cycloaddition reaction of aryl nitrile oxides, generated in situ from N-hydroxyimidoyl chloride, with N-phenylmaleimide and ethyl acrylate, to obtain 3-arylisoxazolines. Both the bases gave excellent results. These polymers were reusable, safe to use, and provided good alternative for organic nonreusable bases like pyridine and triethylamine which are hazardous.

description: We solve the Dirac radial equation for a nucleon in a scalar Woods-Saxon potential well of depth $V_0$ and radius $r_0$. A sequence of values for the depth and radius are considered. For shallow potentials with $-1000 MeV\lesssim V_0 < 0$ the wave functions for the positive-energy states $Ψ_+(r)$ are dominated by their nucleon component $g(r)$. But for deeper potentials with $V_0 \lesssim -1500 MeV $ the $Ψ_+(r)$s begin to have dominant anti-nucleon component $f(r)$. In particular, a special intruder state enters with wave function $Ψ_{1/2}(r)$ and energy $E_{1/2}$. We have considered several $r_0$ values between 2 and 8 fm. For $V_0 \lesssim -2000 MeV$ and the above $r_0$ values, $Ψ_{1/2}$ is the only bound positive-energy state and has its $g(r)$ closely equal to $-f(r)$, both having a narrow wave-packet shape centered around $r_0$. The $E_{1/2}$ of this state is practically independent of $V_0$ for the above $V_0$ range and obeys closely the relation $E_{1/2}=\frac{\hbar c}{r_0}$.

Visual binary stars: data to investigate formation of binaries

description: Statistics of orbital parameters of binary stars as well as statistics of their physical characteristics bear traces of star formation history. However, statistical investigations of binaries are complicated by lacking or incomplete observational data and by a number of observational selection effects. Visual binaries are the most numerous observed binaries, the number of pairs exceeds 130000. The most complete list of presently known visual binary stars was compiled by cross-matching objects and combining data of the three largest catalogues of visual binaries. It was supplemented by the data on parallaxes, multicolor photometry, spectral characteristics of the stars of this list taken from other catalogues. This allowed us to compensate partly for the lack of observational data for these objects. Combined data allowed us to check validity of observational values and to investigate statistics of the orbital and physical parameters of visual binaries. Corrections for incompleteness of observational data are discussed. Obtained datasets and modern distributions of binary parameters will be used to reconstruct the initial distributions and parameters of the function of star formation for binary systems.

Dualities in CHL-Models

description: We define a very general class of CHL-models associated with any string theory (bosonic or supersymmetric) compactified on an internal CFT C x T^d. We take the orbifold by a pair (g,δ), where g is a (possibly non-geometric) symmetry of C and δis a translation along T^d. We analyze the T-dualities of these models and show that in general they contain Atkin-Lehner type symmetries. This generalizes our previous work on N=4 CHL-models based on heterotic string theory on T^6 or type II on K3 x T^2, as well as the `monstrous' CHL-models based on a compactification of heterotic string theory on the Frenkel-Lepowsky-Meurman CFT V^{\natural}.

Clonal evolution of ovarian high grade serous carcinoma
Creators: name: Cheng, Zhao
Publisher: name: Imperial College London
Year: 2022

description: Ovarian high-grade serous carcinoma (HGSC) is usually diagnosed at late stage. I investigated whether late-stage HGSC has unique genomic characteristics consistent with acquisition of evolutionary advantage compared with early-stage tumours and the genomic dynamic changes in the evolution process of HGSC. Targeted next-generation sequencing and shallow whole-genome sequencing (sWGS) were performed on samples from 43 chemotherapy-naive patients with FIGO stage I-IIA HGSC to investigate somatic mutations and copy-number (CN) alterations (SCNA). I compared results to pretreatment samples from 52 patients with late stage IIIC/IV HGSC from the BriTROC-1 study. In addition, I also collected p53 signatures, serous tubal intraepithelial carcinomas (STIC), primary and metastatic tumours from five patients as a separate cohort. Age of diagnosis did not differ between early-stage and late-stage patients (median 61.3 years vs. 62.3 years, respectively). TP53 mutations were near-universal in both cohorts (89% early- stage, 100% late-stage), and there were no significant differences in the rates of other somatic mutations, including BRCA1 and BRCA2. I also did not observe cohort-specific focal SCNA that could explain biological behavior. However, ploidy was higher in late-stage (median, 3.0) than early-stage (median, 1.9) samples. Seven copy number signatures, recurrent patterns of copy number change that reflect the imprint of underlying mutational process, had previously been derived from late stage high grade serous carcinomas [1]. CN signature exposures were significantly different between cohorts, with greater relative signature 3 exposure in early-stage and greater signature 4 in late-stage. Signature 3 is associated with BRCA1/2 homologous recombination deficiency pathway and good overall survival. Signature 4 is associated with abnormalities in the PI3K/AKT signalling pathway as well as and whole genome duplication. Unsupervised clustering based on CN signatures identified three clusters that were prognostic. In the STIC cohort, all p53 signatures were diploid. Two patients showed no significant difference in ploidies across samples. However, in three patients, ploidy increase was apparent in STIC lesions as well as primary and metastatic lesions. Early-stage and late-stage HGSCs have highly similar patterns of mutation and focal SCNA. However, CN signature analysis showed that late-stage disease has distinct signature exposures consistent with whole-genome duplication. The STIC cohort provides some evidence that complex genomic alterations can occur very early in the development of HGSC development.

description: Flavor-twisted boundary conditions can be used for exponential reduction of finite volume artifacts in flavor-averaged observables in lattice QCD calculations with $SU(N_f)$ light quark flavor symmetry. Finite volume artifact reduction arises from destructive interference effects in a manner closely related to the phase averaging which leads to large $N_c$ volume independence. With a particular choice of flavor-twisted boundary conditions, finite volume artifacts for flavor-singlet observables in a hypercubic spacetime volume are reduced to the size of finite volume artifacts in a spacetime volume with periodic boundary conditions that is four times larger.

description: Focusing on the history of prehistoric archaeology in the 20th century, this papers shows (1) that statistical multidimensional analyses were carried out by a new kind of actors who challenged the previous common language shared by prehistorians. This fundamental change was important, considering that (2) language is a fundamental point for the epistemology of archaeology. However, a comparison of multidimensional analyses applications over time shall make clear that (3) the differences are mostly a generational matter: the transmission processes between them will be addressed.

description: The present panorama of HPC architectures is extremely heterogeneous, ranging from traditional multi-core CPU processors, supporting a wide class of applications but delivering moderate computing performance, to many-core GPUs, exploiting aggressive data-parallelism and delivering higher performances for streaming computing applications. In this scenario, code portability (and performance portability) become necessary for easy maintainability of applications; this is very relevant in scientific computing where code changes are very frequent, making it tedious and prone to error to keep different code versions aligned. In this work we present the design and optimization of a state-of-the-art production-level LQCD Monte Carlo application, using the directive-based OpenACC programming model. OpenACC abstracts parallel programming to a descriptive level, relieving programmers from specifying how codes should be mapped onto the target architecture. We describe the implementation of a code fully written in OpenACC, and show that we are able to target several different architectures, including state-of-the-art traditional CPUs and GPUs, with the same code. We also measure performance, evaluating the computing efficiency of our OpenACC code on several architectures, comparing with GPU-specific implementations and showing that a good level of performance-portability can be reached.
