description: Choosing the right mating partner is one of the most critical decisions in the life of a sexually reproducing organism and is the basis of sexual selection. This choice is usually assumed to be made by one or both of the sexual partners. Here, we describe a system in which a third party – the siblings – promote outbreeding by their sisters: workers of the tiny ant Cardiocondyla elegans carry female sexuals from their natal nest over several meters and drop them in the nest of another, unrelated colony to promote outbreeding with wingless, stationary males. Workers appear to choose particular recipient colonies into which they transfer numerous female sexuals. Assisted outbreeding and indirect female choice in the ant C. elegans are comparable to human matchmaking and suggest a hitherto unknown aspect of natural history – third party sexual selection. Our study highlights that research at the intersection between social evolution and reproductive biology might reveal surprising facets of animal behavior.

description: We derive a Jacobi-Trudi type formula for Jack functions of rectangular shapes. In this formula, we make use of a hyperdeterminant, which is Cayley's simple generalization of the determinant. In addition, after developing the general theory of hyperdeterminants, we give summation formulae for Schur functions involving hyperdeterminants, and evaluate Toeplitz-type hyperdeterminants by using Jack function theory.

description: [Context] Open Source Software (OSS) is nowadays used and integrated in most of the commercial products. However, the selection of OSS projects for integration is not a simple process, mainly due to a of lack of clear selection models and lack of information from the OSS portals. [Objective] We investigate the factors and metrics that practitioners currently consider when selecting OSS. We also investigate the source of information and portals that can be used to assess the factors, as well as the possibility to automatically extract such information with APIs. [Method] We elicited the factors and the metrics adopted to assess and compare OSS performing a survey among 23 experienced developers who often integrate OSS in the software they develop. Moreover, we investigated the APIs of the portals adopted to assess OSS extracting information for the most starred 100K projects in GitHub. [Result] We identified a set consisting of 8 main factors and 74 sub-factors, together with 170 related metrics that companies can use to select OSS to be integrated in their software projects. Unexpectedly, only a small part of the factors can be evaluated automatically, and out of 170 metrics, only 40 are available, of which only 22 returned information for all the 100K projects. Therefore, we recommend project maintainers and project repositories to pay attention to provide information for the project they are hosting, so as to increase the likelihood of being adopted [Conclusion] OSS selection can be partially automated, by extracting the information needed for the selection from portal APIs. OSS producers can benefit from our results by checking if they are providing all the information commonly required by potential adopters...
Il De divinatione ciceroniano e la polemica di Carneade contro la divinazione
Creators: name: Ciafardone, Giuseppe
Publisher: name: ACME
Year: 2019

description: Nei dialoghi de divinatione (1.7) e de natura deorum (2.162), Cicerone presenta la polemica di Carneade contro la divinazione come una polemica antistoica. In questo articolo, che si ispira ad un studio di D.N. Sedley sugli argomenti teologici carneadei (Cic. nat. deor. 3.29-52; Sext. Emp. adv. math. 9.138-90), mi propongo di dimostrare che tale presentazione non corrisponde pienamente alle reali intenzioni di Carneade. Gli stoici furono senza dubbio i più grandi teorici della divinazione, ragion per cui è legittimo supporre che essi fossero tra i bersagli preferiti da Carneade. Tuttavia, la loro concezione della divinazione è molto vicina a quella comunemente accolta nell’antichità e testimoniata da poeti e filosofi: propongo dunque che gli argomenti di Carneade siano considerati come un attacco alla divinazione per se, e non solo al modo in cui gli stoici la giustificarono filosoficamente.

description: Il progetto « RecRoad – From Aquileia to Singidunum, reconstructing the paths of the Roman travelers » si pone come obiettivo la ricostruzione e mappatura dell’itinerario romano da Aquileia a Singidunum (Belgrado, Serbia) e lo studio del rapporto che univa la viabilità antica al paesaggio naturale e culturale. In questo contesto, un ruolo fondamentale è giocato dall’acqua e dai fiumi, che rendono prospere le città, ma mettono a rischio la sicurezza delle vie di terra. Questo contributo vuole esplorare, attraverso l’analisi del complesso rapporto fra viabilità terrestre e idrografia, tre casi esemplari di questa problematica : il territorio di Aquileia, nella Regio x, e i casi di Neviodunum e di Marsonia in Pannonia Superior. Integrando le fonti disponibili, sarà possibile meglio comprendere i problemi posti dalle diverse situazioni territoriali e ricostruire le scelte attuate dagli ingegneri romani nella costruzione delle strade.

Gain-dependent Purcell enhancement, breakdown of Einstein's relations and superradiance in nanolasers

Year: 2021

description: Light emitters in a single-mode nanolaser interact with the same cavity field, that gives rise to polarization correlations which transform the cavity mode. Usually these correlations are ignored, however, collective phenomena can lead to the distinct sub- and superradiance, whose fully quantum description is challenging. Here, we develop a simple yet rigorous picture of radiative transitions in single-mode nanolasers that accounts for polarization correlations. We show that the collective behavior of emitters modifies the photonic density of states leading to gain-dependent Purcell enhancement of spontaneous emission. Moreover, the stimulated emission rate is dependent on both the photon number and the laser lineshape. As the laser line narrows, stimulated emission becomes stronger than predicted by Einstein's relations and the nanolaser reaches the threshold earlier. Finally, we provide concise, ready-to-use expressions for spontaneous and stimulated emission rates seamlessly describing both conventional and superradiant nanolasers.

description: Costs of producing cotton vary considerably among and within regions. The major factors affecting costs are yields and size of operation, measured by acreage or sales. Most of the differences in total economic costs, ranging in 1987 from $0.58 per pound in the Southwest to $0.85 in the Southern Plains, were due to variations in yield. Large operations were able to keep production costs down by taking advantage of technical efficiencies or economies of size.

description: Avere a che fare con Giulio Sambon significa toccare molti ambiti del contesto artistico dell’Italia ottocentesca. Proprio per questo motivo è difficile delineare la sua figura in una sola occasione e affrontando tutte le prospettive: in lui si fondono contemporaneamente l’anima dello studioso, del collezionista e del mercante per tutte le discipline artistiche, dalla pittura all’archeologia. Il presente contributo propone una ricostruzione basilare di questa figura, ripercorrendo le tappe salienti della vita e dell’attività commerciale, attraverso i rapporti con collezionisti e musei milanesi e stranieri. Gli strumenti utilizzati per il lavoro sono i cataloghi d’asta della sua «impresa di vendite in Italia», i documenti conservati negli archivi di Napoli, Roma e Firenze, ma soprattutto il fondo privato della famiglia Sambon custodito a Parigi presso le Archives Nationales de France.

description: The purpose of the present study is to show that in a particular cosmological model, with an affine equation of state, one can obtain, besides the background given by the scale factor, Hubble and deceleration parameters, a representation in terms of scalar fields and, more important, explicit mathematical expressions for the density contrast and the power spectrum. Although the model so obtained is not realistic, it reproduces features observed in some previous numerical studies and, therefore, it may be useful in the testing of numerical codes and as a pedagogical tool.

description: Abstract: The migration from proprietary GPU drivers of Nvidia towards open-source for the R555-R560 series involves significant security, performance, and feature implications. In this paper, we present a new methodology to improve the security posture of open-source GPU drivers while ensuring optimal performance as well as full-feature support. We are particularly concerned with side-channel vulnerabilities that can be exposed during GPU operation. Our approach is based on (I) identification and mitigation of targeted vulnerabilities using multi-layered security architectures, (II) integration of advanced cryptographic modules with minimal overheads, and (III) runtime monitoring of potential side channels through hardware-like preprocessors. The results show that our proposed implementation tolerates minimum performance degradation under several benchmarks and real-world applications against a variety of attack vectors. Likewise, we also perform a comparative analysis between proprietary driver implementations versus their corresponding open-source drivers concerning features and computational performance to gauge possible challenges influencing the process without compromising functionality or impaired performance for R555-R560 series Nvidia GPUs.The insights in our research shall be beneficial to end-users interested in adopting GPUs extended with secure software stacks using FOSS components as well as developers who intend to transform future iterations of current loyalist vendor-locked GPUs equipped with high-performance hardware features stable/secure firmware into humanitarian promise designs fostering privacy by design principles.
«Le mieux est l’ennemi du bien». Roy Rosenzweig e il dibattito americano sulla public history agli albori del World Wide Web

description: Lo studio prende in esame il contributo fornito da Roy Rosenzweig al dibattito sulla public history tra gli anni Ottanta e i primi anni Duemila, una fase in cui il mondo accademico e quello scolastico iniziavano a scoprire le opportunità e i rischi del digitale. Storico americano di formazione democratica e radicale, Rosenzweig fu tra i primi a riconoscere i vantaggi che il digitale può portare nell’ambito della conservazione documentaria e dell’apprendimento, ma anche nell’educazione alla ricerca storica grazie all’accesso diretto alle fonti. Il saggio mette tuttavia in luce anche i limiti del digitale precocemente individuati da Rosenzweig, quali l’assenza di contestualizzazione delle fonti online e di controlli qualitativi su di esse, nonché le restrizioni del copyright. Rosenzweig suggeriva, infatti, di valutare costi e benefici della nuova tecnologia e ciò che essa comporta dal punto di vista educativo e della ricerca storica, proponendo ai colleghi di impegnarsi per garantire una più ampia democratizzazione della conoscenza e una piena accessibilità delle fonti primarie e secondarie.

description: Οι σχολικές δυσκολίες αφορούν προβλήματα μάθησης, επίδοσης και συμπεριφοράς, τα οποία συνήθως εντοπίζονται στο πλαίσιο της γενικής εκπαίδευσης (Rutter, Taylor, & Hersov, 1994). Μαθητές με τέτοιου είδους προβλήματα δυσκολεύονται ή αδυνατούν να παρακολουθήσουν το πρόγραμμα της τάξης τους και εμφανίζουν σχολική υποεπίδοση. Η ομάδα των μαθητών με χαμηλή σχολική επίδοση είναι ετερογενής και οι παράγοντες που την καθορίζουν ποικίλοι (μαθησιακές δυσκολίες, νοητική καθυστέρηση, διγλωσσία). Το πρώτο βήμα στη διαδικασία αξιολόγησης είναι η ανίχνευση των προβλημάτων και οι δάσκαλοι αναγνωρίζουν τους μαθητές που παρουσιάζουν υποεπίδοση. Στην παρούσα έρευνα ζητήθηκαν οι εκτιμήσεις των εκπαιδευτικών αναφορικά με το ποιοι από τους μαθητές παρουσιάζουν χαμηλή σχολική επίδοση. Στη συνέχεια, σε κάθε παιδί δόθηκε ένα κριτήριο επίδοσης για το μάθημα της γλώσσας καθώς και το Detroit test Μαθησιακής Επάρκειας (DTLA-4), προκειμένου να αναδειχτούν τα διάφορα προφίλ μαθησιακής επάρκειας των μαθητών με χαμηλή επίδοση. Στόχος της έρευνας ήταν η διερεύνηση του βαθμού σύγκλισης των δύο κριτηρίων. Η σύγκλιση θα σήμαινε μειωμένη νοητική ικανότητα και επίδοση, ενώ η απόκλιση θα σηματοδοτούσε πιθανή μαθησιακή δυσκολία με βάση τη θεωρία περί διακύμανσης ικανότητας- επίδοσης (Kavale, 2001. Kavale & Forness, 1995). Η έρευνα πραγματοποιήθηκε σε δείγμα 55 μαθητών Ε’ και Στ’ τάξης με χαμηλή σχολική επίδοση. Τα δεδομένα της αξιολόγησης έγιναν αντικείμενο ποιοτικής και ποσοτικής επεξεργασίας για κάθε μαθητή. Από τα ευρήματα προέκυψε πως επιβεβαιώνεται η αρχική υπόθεση, με τη διαφορά ότι το κριτήριο διακύμανσης δεν είναι από μόνο του αρκετό για να ορίσει το πεδίο των μαθησιακών δυσκολιών (Kavale & Forness, 2000). Τα αποτελέσματα συζητούνται με βάση την τρέχουσα βιβλιογραφία.
description: School difficulties are a heterogeneous group of problems of multi aetiology. Pupils with these problems have difficulties or fail to attend the course of their class having as a result a low school performance. To find out of what kind and how serious this problem may be, overall assessment and differential diagnosis of the student are necessary based on the transdisciplinary approach. The first step in assessment process is to detect such difficulties. Teachers are in position to detect students with low school performance in their classes. In this research low school performance students –detected by their teachers- were assessed by using a curriculum based assessment for language course and DTLA-4 ( Detroit Tests of Learning Aptitude). Results revealed learning profiles for students with low school performance. Additionally, ability – achievement discrepancy is an important but not the only kritirion to define learning difficulties (Kavale & Forness, 2000). Results are discussed according to the current bibliography.

description: The reduced field equations and BPS conditions are derived in Type IIB supergravity for configurations of the Janus type, characterized by an $AdS_4$-slicing of $AdS_5$, and various degrees of internal symmetry and supersymmetry. A generalization of the Janus solution, which includes a varying axion along with a varying dilaton, and has SO(6) internal symmetry, but completely broken supersymmetry, is obtained analytically in terms of elliptic functions. A supersymmetric solution with 4 conformal supersymmetries, SU(3) internal symmetry, a varying axion along with a varying dilaton, and non-trivial $B_{(2)}$ field, is derived analytically in terms of genus 3 hyper-elliptic integrals. This supersymmetric solution is the 10-dimensional Type IIB dual to the $\N=1$ interface super-Yang-Mills theory with SU(3) internal symmetry previously found in the literature.

description: The spherical Fourier-Bessel (SFB) decomposition is a natural choice for the radial/angular separation that allows extraction of cosmological information from large volume galaxy surveys, taking into account all wide-angle effects. In this paper we develop a SFB power spectrum estimator that allows the measurement of the largest angular and radial modes with the next generation of galaxy surveys. The code measures the pseudo-SFB power spectrum, and takes into account mask, selection function, pixel window, and shot noise. We show that the local average effect (or integral constraint) is significant only in the largest-scale mode, and we provide an analytical covariance matrix. By imposing boundary conditions at the minimum and maximum radius encompassing the survey volume, the estimator does not suffer from the numerical instabilities that have proven challenging for SFB analyses in the past. The estimator is demonstrated on simplified but realistic Roman-like, SPHEREx-like, and Euclid-like mask and selection functions. For intuition and validation, we also explore the SFB power spectrum in the Limber approximation. We release the associated public code written in Julia.

description: La storia dell’organizzazione teatrale è costellata di convegni ed eventi volti a discutere sui principali argomenti legati a questo mondo: testi, finanziamenti, rapporti tra pubblico e privato. Il convegno milanese del 15 luglio 1974 promosso dal Partito Socialista Italiano, parte da questi presupposti ma, al contrario di altri eventi simili, vanta una partecipazione cospicua di protagonisti della scena teatrale, sia milanese sia nazionale: Paolo Grassi, Roberto Valentini, Leo Wächter sono solo alcuni dei nomi presenti. Un crogiuolo di idee innovative che hanno modificato radicalmente la visione del settore cultura e che troveranno attuazione nei decenni successivi, fino ad essere visibili nella nostra quotidianità. Contestualizzando gli interventi alla luce degli anni in cui hanno mosso i primi passi, risulta chiaro quanto questo convegno, poco ricordato anche dalla critica più attenta, sia invece una delle pietre miliari nell’ambito dell’organizzazione teatrale e nella creazione della figura professionale dell’operatore culturale.

Learning to recognize objects in images : acquiring and using probabilistic models of appearance
Creators: name: Pope, Arthur R.
Publisher: name: University of British Columbia
Year: 2009

description: We present a method of recognizing three-dimensional objects in intensity images of cluttered scenes, using models learned from training images. By modeling each object with a series of views, representing each view with a large variety of features, and describing each feature probabilistically, our method can learn to recognize objects of unusual complexity. An object is modeled by a probability distribution describing the range of possible variation in the object's appearance. This distribution is organized on two levels. Large variations are handled by partitioning training images into clusters corresponding to distinctly different views of the object. Within each cluster, smaller variations are represented by distributions characterizing uncertainty in the presence, position, and measurements of various discrete features of appearance. Many types of features may be used, ranging in abstraction from segments of intensity edges to perceptual groupings and regions. Our learning method combines two activities: (a) an incremental conceptual clustering algorithm identifies groups of training images corresponding to distinct views of the object; (b) a generalization algorithm consolidates each cluster to produce a summary description characterizing its most prominent features. The method produces models that are both economical and representative, balancing these competing goals through an application of the minimum description length principle. Recognition requires matching features of a model with those of an image. Our matching method is a form of alignment: from hypothesized feature pairings it estimates a viewpoint transformation; from that it finds additional pairings, and so on. The method uses constraints based on features' positions, numeric measurements, and relations, assigning to each an importance commensurate with its uncertainty as recorded by the model. Decisions are ordered so that more certain features are paired sooner, while ambiguous choices are postponed for later resolution, when additional constraints may be known. We also describe a system implemented to test our recognition learning method. Experiments demonstrate the system's performance at tasks including learning to recognize complex objects in cluttered scenes, and learning to discriminate two quite similar objects.

Publ. {\bf 31} (2005), 131-176.It was also posted as {arXiv:math/0702587v1} [math.HO] 20 Feb 2007. This paper was meant for a series of talks at the Bratislava Workshop on the density concept, May 2004. A number of the very many facets of ultrafilters are reviewed (some of them, a bit cursorily, as is to be expected in a short space, and time) including Condorcet's Paradox, ultraproducts and the theory of infinitesimals (non-standard analysis), Banach generalized limits in sequence spaces, Choquet's limits for families of closed sets in general topology and intrinsic geometry, representations of topologies as binary relations among ultrafilters, additive bases in number theory.

description: Next generation neutrino oscillation experiments like DUNE and T2HK are multi-purpose observatories, with a rich physics program beyond oscillation measurements. A special role is played by their near detector facilities, which are particularly well-suited to search for weakly coupled dark sector particles produced in the primary target. In this paper, we demonstrate this by estimating the sensitivity of the DUNE near detectors to the scattering of sub-GeV DM particles and to the decay of sub-GeV sterile neutrinos ("heavy neutral leptons"). We discuss in particular the importance of the DUNE-PRISM design, which allows some of the near detectors to be moved away from the beam axis. At such off-axis locations, the signal-to-background ratio improves for many new physics searches. We find that this leads to a dramatic boost in the sensitivity to boosted DM particles interacting mainly with hadrons, while for boosted DM interacting with leptons, data taken on-axis leads to marginally stronger exclusion limits. Searches for heavy neutral leptons perform equally well in both configurations.

description: Food expenditures in the United States have risen almost every year since the end of the Great Depression. However, income has risen faster (chiefly because of the increasing number of families with more than one wage earner), so food spending as a percentage of income has declined. Higher income households spend more money on food, but use a smaller share of income, than lower income households. Measures of food expenditures and income vary according to how income is measured, what expenses are counted, and who is paying for the food.

description: Aims: To calculate transition rates from ground and excited states in neutral oxygen atoms due to electron collisions for non-LTE modelling of oxygen in late-type stellar atmospheres, thus enabling reliable interpretation of oxygen lines in stellar spectra. Methods: A 38-state R-matrix calculation in LS-coupling has been performed. Basis orbitals from the literature (Thomas et al.) are adopted, and a large set of configurations are included to obtain good representations of the target wavefunctions. Rate coefficients are calculated by averaging over a Maxwellian velocity distribution. Results: Estimates for the cross sections and rate coefficients are presented for transitions between the seven lowest LS states of neutral oxygen. The cross sections for excitation from the ground state compare well with existing experimental and recent theoretical results.

description: During the past few years, mostly as a result of the GDPR and the CCPA, websites have started to present users with cookie consent banners. These banners are web forms where the users can state their preference and declare which cookies they would like to accept, if such option exists. Although requesting consent before storing any identifiable information is a good start towards respecting the user privacy, yet previous research has shown that websites do not always respect user choices. Furthermore, considering the ever decreasing reliance of trackers on cookies and actions browser vendors take by blocking or restricting third-party cookies, we anticipate a world where stateless tracking emerges, either because trackers or websites do not use cookies, or because users simply refuse to accept any. In this paper, we explore whether websites use more persistent and sophisticated forms of tracking in order to track users who said they do not want cookies. Such forms of tracking include first-party ID leaking, ID synchronization, and browser fingerprinting. Our results suggest that websites do use such modern forms of tracking even before users had the opportunity to register their choice with respect to cookies. To add insult to injury, when users choose to raise their voice and reject all cookies, user tracking only intensifies. As a result, users' choices play very little role with respect to tracking: we measured that more than 75% of tracking activities happened before users had the opportunity to make a selection in the cookie consent banner, or when users chose to reject all cookies.

description: Aublysodon, Leidy, 1868.
 In the same publications above cited, Dr. Leidy also described and figured, under the name Deinodon, a number of teeth which he regarded as pertaining to carnivorous Dinosaurs, but later, in 1868, he made a new genus, Aublysodon, for some of these teeth which differed materially in form from those known to belong to such Dinosaurs. * The teeth regarded by Leidy as characteristic of Aublysodon are represented in figures 35—45, Plate IX, of the Transactions above quoted, and the best preserved tooth of this series, which Leidy suspected to be an incisor, is shown in figures 41-45. The latter figures are carefully reproduced on Plate III, figure 4, of the present article, and two other similar teeth are represented on the same plate. They all have the same characteristic chiselshaped crowns, covered with a thin coat of enamel, and show indications of wear.
 The teeth referred by Leidy to the genus Aublysodon and many others of the same general character since discovered may be divided into the four following groups, all the specimens of which appear to be somewhat curved either to the right or left: '
(1) Large teeth (Leidy’s figures 37-40) having both edges crenulated, and the posterior ridge between them broad. The wear of the apex is apparently posterior.

description: Gravitational lensing of gravitational waves (GWs) is a powerful probe of the matter distribution in the universe. Here we revisit the wave-optics effects induced by dark matter (DM) halos on the GW signals of merging massive black hole binaries (MBHBs), and we study the possibility of discerning these effects using the Laser Interferometer Space Antenna (LISA). In particular, we include the halos in the low-mass range of $\rm 10^5-10^8\, M_\odot$ since they are the most numerous according to the cold DM model. We simulate the lensed signals corresponding to a wide range of impact parameters, and we find distinguishable deviation from the standard best-fit GW templates even when the impact parameter is as large $y\simeq50$. Consequently, we estimate that over $(0.1-1.6)\%$ of the MBHBs in the mass range of $\rm 10^{5.0}-10^{6.5}\, M_\odot$ and the redshift range of $4-10$ should show detectable wave-optics effects. This probability is one order of magnitude higher than that derived in previous works. The uncertainty comes mainly from the mass function of the DM halos. Not detecting any signal during the LISA mission would imply that DM halos with $\rm 10^5-10^8\, M_\odot$ are less numerous than what the cold DM model predicts.

Photometric Observation and Numerical Simulation of Early Superhumps in BC UMa during the 2003 Superoutburst

description: We carried out time-resolved photometric observations of an SU UMa type dwarf nova, BC UMa, during its superoutburst in February 2003. We detect early superhumps (or outburst orbital humps) during the first two days of the outburst. The period of early superhumps is 0.06258(13) d and the amplitude is 0.04 mag. After the early superhump phase, common superhumps with an amplitude of 0.3 mag and a period of 0.064466(16) d developed. The change rate of superhump periods was positive through the superoutburst. The superhump period excess is 3% and we derive a mass ratio of 0.13. This is twice as large as that of WZ Sge, suggesting that the mechanism of early superhumps in BC UMa is not the 2:1 resonance which was proposed in WZ Sge. We have modelled early superhump light curves including irradiation effects of the accretion disk and secondary star by the white dwarf and accretion disk. The observed early superhumps can be reproduced when two-armed spirals appear on the accretion disk. We have found the long term data taken from AAVSO, VSOLJ and VSNET shows BC UMa has normal outbursts with a maximum magnitude of V~13 and two types of superoutbursts: one has a short duration (around 10 days) and faint maximum magnitude (V~12.5), the other has a long duration (around 20 days) and bright maximum (V~11-11.5). BC UMa is the first example of dwarf novae showing the two types of superoutbursts. The supercycle of BC UMa is between 600 days and 1000 days. This is shorter than WZ Sge type dwarf novae and longer than normal SU UMa type stars. This phenomenon suggests that BC UMa is an intermediate dwarf nova between WZ Sge and SU UMa.

description: Deep convolutional neural network (DCNN) models have been widely explored for skin disease diagnosis and some of them have achieved the diagnostic outcomes comparable or even superior to those of dermatologists. However, broad implementation of DCNN in skin disease detection is hindered by small size and data imbalance of the publically accessible skin lesion datasets. This paper proposes a novel single-model based strategy for classification of skin lesions on small and imbalanced datasets. First, various DCNNs are trained on different small and imbalanced datasets to verify that the models with moderate complexity outperform the larger models. Second, regularization DropOut and DropBlock are added to reduce overfitting and a Modified RandAugment augmentation strategy is proposed to deal with the defects of sample underrepresentation in the small dataset. Finally, a novel Multi-Weighted New Loss (MWNL) function and an end-to-end cumulative learning strategy (CLS) are introduced to overcome the challenge of uneven sample size and classification difficulty and to reduce the impact of abnormal samples on training. By combining Modified RandAugment, MWNL and CLS, our single DCNN model method achieved the classification accuracy comparable or superior to those of multiple ensembling models on different dermoscopic image datasets. Our study shows that this method is able to achieve a high classification performance at a low cost of computational resources and inference time, potentially suitable to implement in mobile devices for automated screening of skin lesions and many other malignancies in low resource settings.

description: Free-ranging populations of wild pigs (also called feral swine) are present in at least 18 States in this country. Some experts estimate their numbers at over 1 million. Additionally, private landowners in several States have set up enclosed hunting preserves stocked with wild pigs. These wild animals have become popular for sport hunting, but unfortunately, wild pigs can cause a great deal of damage. Hunters, farmers, and landowners should be aware that wild pigs can harbor infectious diseases and can destroy crops, livestock pastures, native plants, and wildlife habitat. Moving wild pigs to new areas or allowing them onto farms that have domestic pigs can have disastrous consequences.
