description: The text presented here is a fictional dialogue between giants of mathematics aimed at provoking reflection.It is not a new conjecture, hypothesis, or theory, but rather the acknowledgment of a mathematical fact that becomes obvious and self-evident once pointed out.

Only the prime numbers up to x/2 are necessary and sufficient to compose or structure all composite numbers up to x, with x>3.This is undeniable. It is pure arithmetic that reveals the duality of primes.

The dramatized text plays with the possibility that Gauss, who proposed π(x) as a teenager, already knew this but considered it too trivial to warrant any comment.

However, the duality of primes naturally provokes oscillations around x/2, and, as if by magic—no, by logic—immediately collapses the RH when this duality is understood.By Riemann’s own explicit formula, it becomes evident that any zero out of place would violate this primal duality, which is absurd.

But simple truths like this are not easy to accept. They are ignored, rejected, and ridiculed. Look at what happened with the discovery of the square root of 2.

I am neither a mathematician nor a physicist, just an economist with some expertise in data science who has seen too much.The dramatized text seemed to me the best way to communicate this observation to a broader audience.The play is accompanied by a more formal and didactic text with all the computational evidence presented (https://doi.org/10.5281/zenodo.15086121), as well as a link to an open GitHub repository (https://github.com/costaalv/spectral-structure-of-the-primes) for those who wish to replicate the observations.

Finally, an open request:If you listen to the primes and what they have to say, help me spread this truth throughout the academic community.Truth, once revealed, cannot be ignored.I kindly ask for your collaboration and endorsement to help publish the didactic text on arXiv.

The primes thank you!

description: A radar and communication integration (RCI) system has great flexibility in allocating antenna resources to guarantee both radar and communication performance. This paper considers the array allocation problems for multiple target localization and multiple platforms communication in an RCI network. The objective of array allocation is to maximize the communication capacity for each channel and to minimize the localization error for each target. In this paper, we firstly build a localization and communication model for array allocation in an RCI network. Minorization maximization (MM) is then applied to create surrogate functions for multiple objective optimization problems. The projected gradient descent (PGD) method is further employed to solve two array allocation problems with and without a certain communication capacity constraint. Computer simulations are conducted to evaluate the performance of the proposed algorithms. The results show that the proposed algorithms have improved localization and communication performance after efficiently allocating the array resource in the RCI network.

description: Electronic states in a crystal can localize due to strong electron-phonon (e-ph) interactions, forming so-called small polarons. Methods to predict the formation and energetics of small polarons are either computationally costly or not geared toward quantitative predictions. Here we show a formalism based on canonical transformations to compute the polaron formation energy and wavefunction using ab initio e-ph interactions. Comparison of the calculated polaron and band edge energies allows us to determine whether charge carriers in a material favor a localized small polaron over a delocalized Bloch state. Due to its low computational cost, our approach enables efficient studies of the formation and energetics of small polarons, as we demonstrate by investigating electron and hole polaron formation in alkali halides and metal oxides and peroxides. We outline refinements of our scheme and extensions to compute transport in the polaron hopping regime.

description: Prehospital post-resuscitation hypotension and hypoxia have been associated with adverse outcomes in the context of out-of-hospital cardiac arrest (OHCA). We aimed to investigate the association between clinical outcomes and post-resuscitation hypoxia alone, hypotension alone, and combined hypoxia and hypotension. We used the 2018-2021 ESO annual datasets to conduct this study. All EMS-treated non-traumatic OHCA patients who had a documented prehospital return of spontaneous circulation (ROSC) and two or more SpO2 readings and systolic blood pressures recorded were evaluated for inclusion. Patients who were less than 18 years of age, pregnant, had a do-not-resuscitate order or similar, achieved ROSC after bystander CPR only, or had an EMS-witnessed cardiac arrest were excluded. Multivariable logistic regression adjusted for standard Utstein factors and highest prehospital Glasgow Coma Scale (GCS) score was used to investigate the association between hypoxia, hypotension, and outcomes. We analyzed data for 17,943 patients, of whom 3,979 had hospital disposition data. Hypotension and hypoxia were not documented in 1,343 (33.8%) patients, 1,144 (28.8%) had only hypoxia documented, 507 (12.7%) had only hypotension documented, and 985 (24.8%) had both hypoxia and hypotension documented. In comparison to patients who did not have documented hypotension or hypoxia, patients who had documented hypoxia (aOR: 1.76 [1.38, 2.24]), documented hypotension (aOR: 3.00 [2.15, 4.18]), and documented hypoxia and hypotension combined (aOR: 4.87 [3.63, 6.53]) had significantly increased mortality. The relationship between mortality and vital sign abnormalities (hypoxia and hypotension > hypotension > hypoxia) was observed in every evaluated subgroup. In this large dataset, hypotension and hypoxia were independently associated with mortality both alone and in combination. Compared to patients without documented hypotension and hypoxia, patients with documented hypotension and hypoxia had nearly five-fold greater odds of mortality.

description: In search for the possible astrophysical sources behind origination of the diverse gamma-ray bursts, cluster analyses are performed to find homogeneous groups, which discover an intermediate group other than the conventional short and long bursts. However, very recently, few studies indicate a possibility of the existence of more than three (namely five) groups. Therefore, in this paper, fuzzy clustering is conducted on the gamma-ray bursts from the final 'Burst and Transient Source Experiment' catalog to cross-check the significance of these new groups. Meticulous study on individual bursts based on their memberships in the fuzzy clusters confirms the previously well-known three groups against the newly found five.

description: Boolean networks with canalizing functions are used to model gene regulatory networks. In order to learn how such networks may behave under evolutionary forces, we simulate the evolution of a single Boolean network by means of an adaptive walk, which allows us to explore the fitness landscape. Mutations change the connections and the functions of the nodes. Our fitness criterion is the robustness of the dynamical attractors against small perturbations. We find that with this fitness criterion the global maximum is always reached and that there is a huge neutral space of 100% fitness. Furthermore, in spite of having such a high degree of robustness, the evolved networks still share many features with "chaotic" networks.

description: No abstracts are to be cited without prior reference to the author. Catch data collation in InterCatch is the culmination of the catch sampling process rather than the start of the stock assessment process, and as such, the guiding principles should have a basis in statistics rather than fisheries science. Here we compare the InterCatch data collation algorithms to statistical methods, then, using North Sea haddock as a case study, we demonstrate exploratory data analysis which can be used to inform decisions on grouping both sampled and unsampled data. We suggest a consistent approach to data submission and collation and the pertinent information to include in stock assessment working group reports and we comment on the role of InterCatch within a regional sampling design and the implications of this for the regional database.
Compositional model checking of partially ordered state spaces
Creators: name: Hazelhurst, Scott
Publisher: name: University of British Columbia
Year: 2009

description: Symbolic trajectory evaluation (STE) — a model checking technique based on partial order representations of state spaces — has been shown to be an effective model checking technique for large circuit models. However, the temporal logic that it supports is restricted, and as with all verification techniques has significant performance limitations. The demand for verifying larger circuits, and the need for greater expressiveness requires that both these problems be examined. The thesis develops a suitable logical framework for model checking partially ordered state spaces: the temporal logic TL and its associated satisfaction relations, based on the quaternary logic Q. TL is appropriate for expressing the truth of propositions about partially ordered state spaces, and has suitable technical properties that allow STE to support a richer temporal logic. Using this framework, verification conditions called assertions are defined, a generalised version of STE is developed, and three STE-based algorithms are proposed for investigation. Advantages of this style of proof include: models of time are incorporated; circuits can be described at a low level; and correctness properties are expressed at a relatively high level. A primary contribution of the thesis is the development of a compositional theory for TL assertions. This compositional theory is supported by the partial order representation of state space. To show the practical use of the compositional theory, two prototype verification systems were constructed, integrating theorem proving and STE. Data is manipulated efficiently by using binary decision diagrams as well as symbolic data representation methods. Simple heuristics and a flexible interface reduce the human cost of verification. Experiments were undertaken using these prototypes, including verifying two circuits from the IFIP WG 10.5 Benchmark suite. These experiments showed that the generalised STE algorithms were effective, and that through the use of the compositional theory it is possible to verify very large circuits completely, including detailed timing properties.

description: The present study draws on the literary production of the greek actress Speranza Vrana, who served the light musical theatre from the beginning of the second half of the twentieth century until almost the end of it. Firstly, we will deal with some biographical details and also with the presentation of each one of her thirteen books written at the last twenty years of her life. They are divided into three main categories: a) biographical, b) novels and c) soul-searching. Secondly, we will attempt to discern the similarities and differences which are detected in her passages, related to her own literary style, the content and the form of each category mentioned above. All our observations are based on textual examples. A last step will consist of identifying all the information arising from Vrana’s literary production referring to the life, the profession and the working conditions of actors in the aftermath of World War II in Greece. The paper concludes with a gallery consisting of the thirteen covers of Speranza Vrana’s books.

description: We report on multi-frequency radio observations of the new magnetar Swift J1818.0-1607, following it for more than one month with high cadence. The observations commenced less than 35 hours after its registered first outburst. We obtained timing, polarisation and spectral information. Swift J1818.0-1607 has an unusually steep spectrum for a radio emitting magnetar and also has a relatively narrow and simple pulse profile. The position angle swing of the polarisation is flat over the pulse profile, possibly suggesting that our line-of-sight grazes the edge of the emission beam. This may also explain the steep spectrum. The spin evolution shows large variation in the spin-down rate, associated with four distinct timing events over the course of our observations. Those events may be related to the appearance and disappearance of a second pulse component. The first timing event coincides with our actual observations, while we did not detect significant changes in the emission properties which could reveal further magnetospheric changes. Characteristic ages inferred from the timing measurements over the course of months vary by nearly an order of magnitude. A longer-term spin-down measurement over approximately 100 days suggests an characteristic age of about 500 years, larger than previously reported. Though Swift J1818.0-1607 could still be one of the youngest neutron stars (and magnetars) detected so far, we caution using the characteristic age as a true-age indicator given the caveats behind its calculation.

description: Variations in the reflective properties of the bulk material that comprises the surface of land-dominated planets will affect the planetary energy balance by interacting differently with incident radiation from the host star. Furthermore, low-mass cool stars, such as nearby M8V dwarf TRAPPIST-1, emit a significant fraction of their flux in longer wavelengths relative to the Sun in regions where terrestrial materials may exhibit additional variability in albedo. Using the Community Earth System Model (CESM) we investigate the effect of the composition of the land surface and its albedo on planetary climate in the context of spatially homogeneous, entirely land-covered planets with dry atmospheres at the orbital separation of TRAPPIST-1d, TRAPPIST-1e, and TRAPPIST-1f. We use empirically derived spectra of four terrestrial compositional endmembers (granite, calcite, aridisol, and dune sand) and a composite spectrum of TRAPPIST-1 for these simulations and compare these model output to an aquaplanet and several Sol-spectrum control cases. We report a difference of approximately 50 K in global mean surface temperature, variations in atmospheric rotational features, and a reduction in cross-equatorial heat transport between scenarios in which materials with higher albedo in the infrared (calcite and dune sand) were used and those with more absorptive crustal material, such as granite or dry soils. An aquaplanet TRAPPIST-1d scenario results in an unstable runaway greenhouse regime. Therefore, we demonstrate that determining the composition and albedo of continental landmasses is crucial for making accurate determinations of the climate of terrestrial exoplanets.

description: A significant anisotropy of the magnetic-field driven superconductor-insulator transition is observed in thin films of amorphous indium-oxide. The anisotropy is largest for more disordered films which have a lower transition field. At higher magnetic field the anisotropy reduces and even changes sign beyond a sample specific and temperature independent magnetic field value. The data are consistent with the existence of more that one mechanism affecting transport at high magnetic fields.

By using an integral representation of the heat semi-group we find a formal solution for the heat kernel diagonal that gives a generating function for the whole sequence of heat invariants. We show explicitly that the obtained result correctly reproduces the first non-trivial heat kernel coefficient as well as the exact heat kernel diagonals on two-dimensional sphere $S^2$ and the hyperbolic plane $H^2$. We argue that the obtained formal solution correctly reproduces the exact heat kernel diagonal after a suitable regularization and analytical continuation.

description: Optical spectroscopic observations of white dwarf stars selected from catalogs based on the Gaia DR2 database reveal nine new gaseous debris disks that orbit single white dwarf stars, about a factor of two increase over the previously known sample. For each source we present gas emission lines identified and basic stellar parameters, including abundances for lines seen with low-resolution spectroscopy. Principle discoveries include: (1) the coolest white dwarf (Teff~12,720 K) with a gas disk; this star, WD0145+234, has been reported to have undergone a recent infrared outburst; (2) co-location in velocity space of gaseous emission from multiple elements, suggesting that different elements are well-mixed; (3) highly asymmetric emission structures toward SDSSJ0006+2858, and possibly asymmetric structures for two other systems; (4) an overall sample composed of approximately 25% DB and 75% DA white dwarfs, consistent with the overall distribution of primary atmospheric types found in the field population; and (5) never-before-seen emission lines from Na in the spectra of GaiaJ0611-6931, semi-forbidden Mg, Ca, and Fe lines toward WD0842+572, and Si in both stars. The currently known sample of gaseous debris disk systems is significantly skewed towards northern hemisphere stars, suggesting a dozen or so emission line stars are waiting to be found in the southern hemisphere.

In the performed calculations four fixed energies of neutrons with the corresponding wavelengths of 1, 1.8, 3 and 4 $A^0$ are taken into account. We calculate the efficiencies of the converter for electron escapes to frontward and backward hemispheres and their sum, depending on thickness of converting foils. Results of comparison of our calculations with the experimental data are presented.

description: Classical environmental contours are used in structural design in order to obtain upper bounds on the failure probabilities of a large class of designs. Buffered environmental contours serve the same purpose, but with respect to the so-called buffered failure probability. In contrast to classical environmental contours, buffered environmental contours do not just take into account failure vs. functioning, but also to which extent the system is failing. This is important to take into account whenever the consequences of failure are relevant. For instance, if we consider a power network, it is important to know not just that the power supply is failed, but how many consumers are affected by the failure. In this paper, we study the connections between environmental contours, both classical and buffered, and optimal structural design. We connect the classical environmental contours to the risk measure value-at-risk. Similarly, the buffered environmental contours are naturally connected to the convex risk measure conditional value-at-risk. We study the problem of minimizing the risk of the cost of building a particular design. This problem is studied both for value-at-risk and conditional-value-at-risk. By using the connection between value-at-risk and the classical environmental contours, we derive a representation of the design optimization problem expressed via the environmental contour. A similar representation is derived by using the connection between conditional value-at-risk and the buffered environmental contour. From these representations, we derive a sufficient condition which must hold for an optimal design. This is done both in the classical and the buffered case. Finally, we apply these results to solve a design optimization problem from structural reliability.

Ειδικότερα διερευνήθηκε η φύση του αθλήματος ως εγκλιτικός παράγοντας για την εμφάνιση του συνδρόμου. Διακόσιοι έντεκα υγιείς άντρες από όλη την Ελληνική επικράτεια, επιλέγηκαν και χωρίστηκαν σε τρείς ομάδες, με κριτήριο το άθλημα που συμμετείχαν και την αγωνιστική τους εμπειρία.

Όλοι οι συμμετέχοντες συμπλήρωσαν ένα ερωτηματολόγιο δημογραφικών χαρακτηριστικών καθώς και το ερωτηματολόγιο της μυϊκής δυσμορφίας (MDI). Η ανάλυση one-way MANOVA έδειξε στατιστικά σημαντικές διαφορές των μέσων όρων μεταξύ των ομάδων. Το Post Hoc – Scheffe έδειξε ότι η ομάδα Α, εμφάνισε σημαντικές διαφορές σε όλους τους παράγοντες που ελέγχει το MDI σε σύγκριση με τις άλλες δύο ομάδες. Αντίστοιχα η ομάδα Β, εμφάνισε σημαντικές διαφορές σε τέσσερις από τους έξι παράγοντες του MDI σε σύγκριση με την ομάδα Γ. Συμπερασματικά μπορούμε να πούμε ότι η συμμετοχή στον αθλητισμό αλλά και ιδιαίτερα η φύση του αθλήματος πιθανός δρα εγκλιτικά στην εμφάνιση συμπτωμάτων της μυϊκής δυσμορφίας.
description: The purpose of this study was to investigate the appearance of muscle dysmorphia in elite body building athletes. In particular, the nature of the sport as a conducive factor to the syndrome’s appearance was examined. Two hundred and eleven healthy men from all over the Greek area were selected and divided into three groups on the basis of the sport they participated and their athletic experience. Group A: body building athletes (n=55), group B: team athletes (n=87), group C: control (n=69). All the participants filled in a demographic questionnaire as well as the muscle dysmorphia inventory (MDI). The one-way MANOVA analysis revealed statistically significant differences in mean scores between groups. In addition, the Post-Hoc (Scheffe) indicated that group (A) showed significant differences in all six factors controlled by the MDI, in comparison to the other two groups. Respectively, group (B) revealed significant differences in four of six MDI factors in comparison to group (C). In conclusion, we could argue that sport participation and even more the nature of the sport is probably a conducive factor to the appearance of muscle dysmorphia’s symptoms.

description: No abstracts are to be cited without prior reference to the author. Prior to 2013, observer coverage in the Federal Fisheries of Alaska, USA was paid for by fishers at coverage rates set in regulation. Operators “self-selected” which fishing events would carry observers, providing a mechanism for biased observer data. A change to how observers are deployed and funded was initiated in 2008, involved 53 persons, and took five years to complete. Observers are now deployed onto vessels and into processing facilities according to an Annual Deployment Plan (ADP) that is developed by the Government with public review. Although various concessions to the design were made to improve the salability of the new program, the 2013 ADP still incorporates sampling (deployment) frames with randomization to control bias. However it remains a challenge to explain the benefits of the new program to the public since lower coverage rates have resulted from the large differences in the coverage requirements between former and new programs.
Design and implementation of a simple multimedia specification language for the internet

Publisher: name: University of British Columbia
Year: 2009

description: The format of a multimedia document raises more and more concerns as distributed multimedia documents become attractive. This leads to the research in standardizing a multimedia interchange format, such as HyTime and MHEG. However, these standards are not widely accepted in the applications due to their complications. On the other hand, there are lots of commercial multimedia authoring systems in the market. Most of them are designed for the desktop rather than the distributed network. This thesis presents a Simple Multimedia Specification Language (SMSL). The language is simple, text-based and designed to allow the information of a multimedia document to be stored distributely. Also, the authors can define user interactions in a document. Furthermore, the language is extensible, since it allows user-defined actions to be included in a document, and dynamically executed during the presentation. In order to allow the users to read and publish the SMSL documents on the World Wide Web, the SMSL document browser is implemented as a Java Applet and embedded in a web page. Thus, the users can read an SMSL document by visiting the web page through any Java-compatible web browsers, such as Netscape. The SMSL is suitable for practical use, as is demonstrated by distance learning and TOEFL exam examples. Further work is needed in a variety of areas, such as hypermedia and transmission specifications.

description: We present a combined analysis of the kinematics of the Large Magellanic Cloud through its HI gas, carbon stars, and red supergiant stars. After correcting the line-of-sight velocities for the recent accurate measurement of the LMC's space motion, we find that each kinematic tracer clearly defines a flat rotation curve with similar shape but different amplitude for each tracer: 61 km/s for the carbon stars, 80 km/s for the HI, and 107 km/s for the red supergiants. Previously identified tidal HI features are seen to harbor numerous carbon stars, with the tidally disturbed stars comprising 7-15% of the total sample. This discovery implies that we cannot depend on the carbon star sample alone to construct a reliable model of the LMC's gravitational potential. We also find red supergiants with peculiar kinematics, but their association with tidal features is unclear, and may instead be interacting with supergiant HI shell SGS4. In addition, although the local velocity dispersion of the red supergiants is small, ~8 km/s, their velocity dispersion about the carbon star rotation solution is 17 km/s, equal to the velocity dispersion of the carbon stars themselves. We thus appear to be witnessing the tidal heating of the LMC's stellar disk.

description: In this paper, we present a detailed asteroseismological analysis of six GW Vir stars including the observations collected by the TESS mission. We processed and analyzed TESS observations of RX J2117+3412, HS 2324+3944, NGC 6905, NGC 1501, NGC 2371, and K 1-16. We carried out a detailed asteroseismological analysis of these stars on the basis of PG 1159 evolutionary models that take into account the complete evolution of the progenitor stars. In total, we extracted 58 periodicities from the TESS light curves using a standard pre-whitening procedure to derive the potential pulsation frequencies. All the oscillation frequencies that we found are associated with g-mode pulsations with periods spanning from $\sim 817$ s to $\sim 2682$ s. We find constant period spacings for all but one star, which allowed us to infer their stellar masses and constrain the harmonic degree $\ell$ of the modes. We performed period-to-period fit analyses on five of the six analyzed stars. For four stars, we were able to find an asteroseismological model with masses in agreement with the stellar-mass values inferred from the period spacings, and generally compatible with the spectroscopic masses. We estimated the seismological distance and compared it with the precise astrometric distance measured with GAIA. Finally, we find that the period spectrum of K 1-16 exhibits dramatic changes in frequency and amplitude. The high-quality data collected by the TESS space mission, considered simultaneously with ground-based observations, are able to provide a very valuable input to the asteroseismology of GW Vir stars, similar to the case of other classes of pulsating white-dwarf stars. The TESS mission, in conjunction with future space missions and upcoming surveys, will make impressive progress in white-dwarf asteroseismology.

description: A functional ansatz is developed which gives certain elliptic solutions of the Witten-Dijkgraaf-Verlinde-Verlinde (or WDVV) equation. This is based on the elliptic trilogarithm function introduced by Beilinson and Levin. For this to be a solution results in a number of purely algebraic conditions on the set of vectors that appear in the ansatz, this providing an elliptic version of the idea, introduced by Veselov, of a V-system. Rational and trigonometric limits are studied together with examples of elliptic V-systems based on various Weyl groups. Jacobi group orbit spaces are studied: these carry the structure of a Frobenius manifold. The corresponding almost dual structure is shown, in the A_N and B_N and conjecturally for an arbitrary Weyl group, to correspond to the elliptic solutions of the WDVV equations. Transformation properties, under the Jacobi group, of the elliptic trilogarithm are derived together with various functional identities which generalize the classical Frobenius-Stickelburger relations.

description: Among the properties of homogeneity of incidence structures flag-transitivity obviously is a particularly important and natural one. Consequently, in the last decades also flag-transitive Steiner tdesigns (i.e. flag-transitive t-(v,k,1) designs) have been investigated, whereas only by the use of the classification of the finite simple groups has it been possible in recent years to essentially characterize all flag-transitive Steiner 2-designs. However, despite the finite simple group classification, for Steiner t-designs with parameters t > 2 such characterizations have remained challenging open problems for about 40 years (cf. [11, p. 147] and [12, p. 273], but presumably dating back to around 1965). The object of the present paper is to give a complete classification of all flag-transitive Steiner 4-designs. Our result relies on the classification of the finite doubly transitive permutation groups and is a continuation of the author's work [20, 21] on the classification of all flag-transitive Steiner 3-designs.

description: No abstracts are to be cited without prior reference to the author. In 2013, a newly restructured observer program was launched to collect information from the Federal groundfish and halibut fisheries of Alaska. Observer coverage rates are now determined according to an Annual Deployment Plan (ADP) that assigns fishing operations to deployment strata. Where sampling is to occur, fishing trips and vessels are randomly selected for coverage. The Observer Declare and Deploy System (ODDS) facilitates the logging of trips by vessel operators in tripselection, determines the protocol and appropriate probability of selection for that trip, and returns the outcome to the user. For selected trips, logged information is passed to an observer provider company to coordinate scheduling and observer data finalizes logistics information. In contrast, vessel-selections are performed based on past activity every two months. Selected vessels may petition the Government for an inspection and a conditional release from coverage may be granted. The Vessel Assessment Logging System (VALS) facilitates the petition, stores information on the site visit, and constitutes a database on conditional releases. These computer applications provide the necessary data to evaluate observer deployment (and sampling) efficiency of the observer program in near real-time.

description: A key component for optical on-chip communication is an efficient light source. However, to enable low energy per bit communication and local integration with Si CMOS, devices need to be further scaled down. In this work, we fabricate micro- and nanolasers of different shapes in InP by direct wafer bonding on Si. Metal-clad cavities have been proposed as means to scale dimensions beyond the diffraction limit of light by exploiting hybrid photonic-plasmonic modes. Here, we explore the size scalability of whispering-gallery mode light sources by cladding the sidewalls of the device with Au. The metal clad cavities demonstrate room temperature lasing upon optical excitation for Au-clad devices with InP diameters down to 300 nm, while the purely photonic counterparts show lasing only down to 500 nm. Numerical thermal simulations support the experimental findings and confirm an improved heat-sinking capability of the Au-clad devices, suggesting a reduction in device temperature of 473 K for the metal-clad InP nanodisk laser, compared to the one without Au. This would provide substantial performance benefits even in the absence of a hybrid photonic-plasmonic mode. These results give us insight into the benefits of metal-clad designs to downscale integrated lasers on Si.

description: No abstracts are to be cited without prior reference to the author. Quantifying catch has been recognized world-wide as a critical component in the management of fisheries. Statistical estimators using robust sampling methods may yield accurate and imprecise estimates given the variability associated with many at-sea discard species and inability for agencies to obtain high sampling fractions. However, biased estimates can occur if an inappropriate estimator is used. Using Alaska trawl fisheries as a case example, we investigated the statistical properties and implementation issues for three commonly used estimators: the ratio estimator, a simple mean estimator, and a deterministic imputation method that is currently used in federal fisheries off Alaska. We evaluated several statistical proprieties of the estimators in context with the underlying data: bias of the estimators, variability of the estimators, the performance of the estimators in relation species proportion (rarity), and the performance of the variance estimators. Results show that the simple mean estimator had the best performance for vessels landing catch at shoreside processors. The choice of estimator was less clear for vessels processing catch at-sea, due to sensitivity associated with species composition and implementation issues for the simple mean and ratio estimators.

description: Two-dimensional unsteady hydraulic models can be attractive tools for characterizing the inundation dynamics relevant to floodplain forest ecosystems because of their ability to make dynamic, spatially continuous predictions. Such models are challenging to evaluate because they require spatially and temporally extensive datasets that are expensive or logistically difficult to collect. As a result, there are few examples of model evaluation methods intended for ecological applications in terrestrial or semi-terrestrial areas. Here, we demonstrated one evaluation approach using 3D arrays of low-cost temperature sensors to characterize wetted extent, depth and duration. Simulations of observed flood events in two geomorphically distinct river reach exhibited strong agreement with indirect measurements of wetted extent (>80%). Errors in depth prediction (average 24–29 cm) were similar to those of other ecological applications. Discrepancies in simulated flood durations were almost exclusively less than 24 h in length, which we interpreted as acceptable for the intended model applications. We found that unsteady 2D hydraulic models can capture a level of reality in wetted extent, depth and duration appropriate for characterizing key environmental gradients thought to drive forest composition. We also demonstrated a spatio-temporal model evaluation method that can be tailored to specific ecological research questions.
