description: We present the Interactive Task Encoding System (ITES) for teaching robots to perform manipulative tasks. ITES is designed as an input system for the Learning-from-Observation (LfO) framework, which enables household robots to be programmed using few-shot human demonstrations without the need for coding. In contrast to previous LfO systems that rely solely on visual demonstrations, ITES leverages both verbal instructions and interaction to enhance recognition robustness, thus enabling multimodal LfO. ITES identifies tasks from verbal instructions and extracts parameters from visual demonstrations. Meanwhile, the recognition result was reviewed by the user for interactive correction. Evaluations conducted on a real robot demonstrate the successful teaching of multiple operations for several scenarios, suggesting the usefulness of ITES for multimodal LfO.

description:

This short essay presents a number of unpublished 16th to 18th-century documents from the qāḍī-court records of Aleppo related to contracts and arrangements of travel and transport. These documents mirror the importance of Aleppo as a centre of regional and international trade and as a chief halting place on the Anatolian-Syrian pilgrimage route in the classic Ottoman era. The bustling urban and rural world of travelling pilgrims, merchants, high dignitaries, travel agents, camel breeders, camel drivers, and porters returns the image of a society where mobility, despite its hardships, dangers and costs, was a constant and essential feature.

description: Selberg-type integrals that can be turned into constant term identities for Laurent polynomials arise naturally in conjunction with random matrix models in statistical mechanics. Built on a recent idea of Karasev and Petrov we develop a general interpolation based method that is powerful enough to establish many such identities in a simple manner. The main consequence is the proof of a conjecture of Forrester related to the Calogero--Sutherland model. In fact we prove a more general theorem, which includes Aomoto's constant term identity at the same time. We also demonstrate the relevance of the method in additive combinatorics.

Literary Trajectories of Sulaymān al-Ḥalabī, a Hero Who Was Born a Criminal
Creators: name: Potenza, Daniela

description:

On 14 June 1800, Sulaymān al-Ḥalabī, a Syrian student, stabbed to death General Kléber, leader of the French occupation forces in Egypt. A few days later, the first account of the event – the trial documents – was written, translated into the main languages spoken in Cairo and distributed by the French military. Since then, accounts of this fact have multiplied, each presenting Sulaymān al-Ḥalabī in a different manner, ranging from fanatic, to victim, hero, then back to the fanatic and the hero. Comparing the different stories about Sulaymān al-Ḥalabī and relating them to their context of production, this paper explores their possible motives and effects, showing how the character’s literary trajectories depend more on the circumstances in which the stories were written, rather than on a search for truth. Until now, three main tendencies have decided Sulaymān al-Ḥalabī’s destiny: legitimation, mirroring reality and responding to the regime’s propaganda.

description: Large negative oxygen-isotope (16O/18O) effects (OIE's) on the static spin-stripe ordering temperature T_so and the magnetic volume fraction V_m were observed in La_(2-x)Ba_xCuO_4 (x = 1/8) by means of muon spin rotation experiments. The corresponding OIE exponents were found to be alpha_(T_so) = -0.57(6) and alpha_(V_m) = -0.71(9), which are sign reversed to alpha_(T_c) = 0.46(6) measured for the superconducting transition temperature T_c. This indicates that the electron-lattice interaction is involved in the stripe formation and plays an important role in the competition between bulk superconductivity and static stripe order in the cuprates.

description: In this paper, a linear array of 15 MMMS (Micro-Magneto-Mechanical Systems) microvalves is integrated to an open-cavity upstream edge to perform closed-loop flow control experiments. The microvalves can generate both quasi-steady and pulsed jets and have the advantage to be able to follow arbitrary command signals, which is a key for closed-loop flow control. For a freestream velocity of 20 m/s, the open-cavity flow is characterized by a resonant frequency of 128.6 Hz, which sound pressure level is reduced in closed-loop by 9 dB for a total flow rate of 10 L/min.
Raccontarsi con le macerie: voce e autorialità in Fihris di Sinan Antoon

Year: 2020

description:

The great expansion of post-occupation Iraqi fiction, with its overall departure from social realism and its exploration of new genres, has brought along a new conceptualization of the Author. This paper aims to study how a peculiar figure of authoriality is both invoked and projected through narrative voices in Sinan Antoon’s Fihris (2016). A complex and multi-layered text, Antoon’s novel is narrated by human and non-human voices. Yet, despite the scattered and fragmented surface of narration, a hierarchical, almost concentric organizational principle is provided by the relations between the main narrators in a context of metalepsis. The analysis will focus on the strategies of authentication employed by narrators of different diegetic levels in the novel, from the short stories embedded, to the further level of authority provided by the autobiographical elements in the narrative frame.

description: This paper investigates the dynamic behaviour of an aircraft incorporating a semi-aeroelastic hinge (SAH), a hinge device that enables wingtips to be released during gusts and manoeuvres to alleviate the aerodynamic loads, whilst remaining locked in cruise to obtain the optimum aerodynamic shape. A six degree of freedom flight mechanics model incorporating flexible wings and SAH devices is formulated to evaluate dynamic responses of the aircraft to gusts and control surface inputs. The results are compared between models with various hinge conditions and wingtip sizes, where approximately 50% and 20% reduction in the gust and manoeuvre loads are observed once the hinge are released. Furthermore, aircraft dynamic modes are computed and compared between the models with various wing flexibility and hinge positions. It is shown that a SAH device is able to reduce both roll damping and pitch stiffness leading to approximately 50% and 15% improvement in the roll and pitch rates.

description: We investigate how different cosmological parameters, such as those delivered by the WMAP and Planck missions, affect the nature and evolution of dark matter halo substructure. We use a series of flat $Λ$ cold dark matter ($Λ$CDM) cosmological $N$-body simulations of structure formation, each with a different power spectrum but the same initial white noise field. Our fiducial simulation is based on parameters from the WMAP 7th year cosmology. We then systematically vary the spectral index, $n_s$, matter density, $Ω_M$, and normalization of the power spectrum, $σ_8$, for 7 unique simulations. Across these, we study variations in the subhalo mass function, mass fraction, maximum circular velocity function, spatial distribution, concentration, formation times, accretion times, and peak mass. We eliminate dependence of subhalo properties on host halo mass and average over many hosts to reduce variance. While the "same" subhalos from identical initial overdensity peaks in higher $σ_8, n_s$, and $Ω_m$ simulations accrete earlier and end up less massive and closer to the halo center at $z=0$, the process of continuous subhalo accretion and destruction leads to a steady state distribution of these properties across all subhalos in a given host. This steady state mechanism eliminates cosmological dependence on all properties listed above except subhalo concentration and $V_{max}$, which remain greater for higher $σ_8, n_s$ and $Ω_m$ simulations, and subhalo formation time, which remains earlier. We also find that the numerical technique for computing scale radius and the halo finder used can significantly affect the concentration-mass relationship computed for a simulation.

Al-mihna wa’l-huwiyya. Motivational Dimensions of Arabic Heritage Learners in a Professionally-Oriented Education Setting
Creators: name: Golfetto, Marco Aurelio

Year: 2020

description:

This study investigates motivational and professional orientations and identity issues of students of Arab descent majoring in Arabic in a teaching setting oriented to develop vocational and professional language skills. Their motivations for learning the target language were investigated and compared with those of their colleagues of non-Arab descent through a questionnaire that explored motivational factors, job expectations and education history. Apparently, students were prompted to take Arabic classes because of employment concerns and they proved keen on undertaking most of the proposed professions, providing that they were connected with the Arab world. It is also possible to highlight how the study of the language of origin was determined by thoroughly intrinsic motives. Cultural interests and especially identity needs provided the strongest push for the respondents, even in the surveyed education setting, where instrumental motivation was clearly expected to play a major role. Implications can be drawn as regards curriculum design and classroom practice.

Year: 2020

description:

The neurological bimodality theory, espousing the principles of directionality and cerebral hemisphericity, has led to a series of expedients in the field of foreign language teaching, like the use of inductive strategies. Accordingly, this contribution focuses on a methodological proposal stemming from the aforementioned theoretical perspectives and tackles the question of reading in the early phase of Arabic as Foreign Language learning. In doing so it questions how to teach Modern Standard Arabic at beginner level and proposes solutions to it through the use of new technological tools in the service of languages. Specifically, the focus is set on Pre-A1 and A1 levels of the recently issued Companion Volume to the Common European Framework of Reference for Languages. As a result of theoretical reasoning, the ‘Whole-Part-Whole’ method teaching philosophy is presented, theorized and verified in relation to the study of Arabic by non-Arab beginner learners.

description: The past two decades have seen increasingly rapid advances in the field of multi-view representation learning due to it extracting useful information from diverse domains to facilitate the development of multi-view applications. However, the community faces two challenges: i) how to learn robust representations from a large amount of unlabeled data to against noise or incomplete views setting, and ii) how to balance view consistency and complementary for various downstream tasks. To this end, we utilize a deep fusion network to fuse view-specific representations into the view-common representation, extracting high-level semantics for obtaining robust representation. In addition, we employ a clustering task to guide the fusion network to prevent it from leading to trivial solutions. For balancing consistency and complementary, then, we design an asymmetrical contrastive strategy that aligns the view-common representation and each view-specific representation. These modules are incorporated into a unified method known as CLustering-guided cOntrastiVE fusioN (CLOVEN). We quantitatively and qualitatively evaluate the proposed method on five datasets, demonstrating that CLOVEN outperforms 11 competitive multi-view learning methods in clustering and classification. In the incomplete view scenario, our proposed method resists noise interference better than those of our competitors. Furthermore, the visualization analysis shows that CLOVEN can preserve the intrinsic structure of view-specific representation while also improving the compactness of view-commom representation. Our source code will be available soon at https://github.com/guanzhou-ke/cloven.

description: We investigate the dynamics of a single chiral active particle subject to an external torque due to the presence of a gravitational field. Our computer simulations reveal an arbitrarily strong increase of the long-time diffusivity of the gravitactic agent when the external torque approaches the intrinsic angular drift. We provide analytic expressions for the mean-square displacement in terms of eigenfunctions and eigenvalues of the noisy-driven-pendulum problem. The pronounced maximum in the diffusivity is then rationalized by the vanishing of the lowest eigenvalues of the Fokker-Planck equation for the angular motion as the rotational diffusion decreases and the underlying classical bifurcation is approached. A simple harmonic-oscillator picture for the barrier-dominated motion provides a quantitative description for the onset of the resonance while its range of validity is determined by the crossover to a critical-fluctuation-dominated regime.

The paper deals with two countries – Pakistan and Ukraine – that are located at the center of the following two interest triangles: India-Pakistan-Afghanistan (South Asia) and Russia-Ukraine-Moldova (post-Soviet regional security complex). Despite their considerable differences, they have similar problems with their geopolitical neighbours in the context of territorial conflicts. Existing issues with neighbouring countries give Pakistan and Ukraine the status of a ‘middle state’, which is characterized by threatening its territorial integrity and becoming an object of ‘penetrating’ into its RSC (regional security complex) for the states from neighbouring regions.

Recent studies have reported that the mausoleum of Aḥmad Shāh I Bahmanī (r. 1422-1436), in Ashtur (Karnataka), is frequented by both Muslims and Vīraśaivas. Now, setting out from the pilgrimage performed on the occasion of the sovereign’s ʿurs, the aim of the present contribution is to analyze some of the architectural sites that are touched by the pilgrimage, and to examine how their spaces are understood and perceived by the devotees. The paper aims to shed light on the coexistence of these two religious groups and on the way in which certain forms of competition and negotiation have come to be transposed onto the cultural and historical landscape.

Atypical Compound Verb Constructions in Hindi/Urdu

Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2020

description:

While a lot of research has already been done on defining compound verb constructions and understanding their semantic and pragmatic usages, there is still a gap when it comes to our understanding of atypical compound verb constructions where transitive polar verbs are paired with intransitive vector verbs and vice versa. In this paper we focus on atypical constructions with two intransitive vector verbs: jānā and baiṭhnā. We collate and review the different meanings that scholars have ascribed to these constructions and present our own analysis. We conclude that the main reason behind using an intransitive vector verb with a transitive polar verb is to reduce the transitivity of the action by implying reduced agency on the part of the Agent-like argument of the sentence. In addition to that, the use of an intransitive vector verb with a transitive polar verb also tells us which argument in the sentence is affected by the action from the point of view of the speaker. However, sometimes atypical constructions are also used by the speaker to express his/her shock or astonishment over a particular event, thus imposing his/her own ideas about agency, volitionality, and affectedness on the action being observed.

MF Husain’s Hindi Autobiography Em. Ef. Husain kī kahānī apnī zubānī

Year: 2020

description:

Drawing from Elizabeth Grosz’s notion of the body as a socio-cultural artefact and the exterior of the subject bodies as psychically constructed, and Rosi Braidotti’s concept of nomadic identities, in this article I introduce world-renowned Indian painter MF Husain’s verbal and visual autobiography Em. Ef. Husen kī kahānī apnī zubānī as a series of sketches of a performative self, surfing the world in space and time. Bodies and spaces are envisioned as “assemblages or collections of parts” in constant movement, crossing borders and creating relationships with other selves and other spaces. People and places become a catalyst for manifestations of the self in art – MF Husain being foremost a painter – and eventually also in literature. I look for strategies that MF Husain uses in order to construct or deconstruct the self through crossings and linkages. I try to investigate how the self is performed inside and outside private and public spaces, how the complex (sometimes even contradictory) relationship between self and community is portrayed, and how this autobiography does articulate notions of (imagined) community/ies, nationalism, transnational subjectivity, nostalgia.

description: In this paper, we theoretically propose a method to simulate the longitudinal relaxation of a single qubit by coupling it to an auxiliary qubit. In order to mimic the finite-temperature relaxation, we utilize the Hamiltonian-ensemble approach [Kropf, Gneiting, and Buchleitner, Phys. Rev. X 6, 031023 (2016)] and in each realization the auxiliary qubit possesses a random level spacing. The longitudinal relaxation arises as a consequence of the ensemble average and the interaction between the working qubit and the auxiliary qubit. Furthermore, we apply this approach to investigate the influence of the longitudinal relaxation and the transverse relaxation on the entanglement dynamics of two qubits. It is discovered that the sudden death of the entanglement will occur as long as the longitudinal relaxation is present. The transverse relaxation assists the longitudinal relaxation and thus accelerates the finite-time disentanglement.

Sexuality as Translation. Locating the “Queer” in Vietnamese Debates on Sexuality
Creators: name: Tran, Richard Quang-Anh
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2020

description:

Transnational debates on LGBTQ identities have centred on the conflict between universalism and particularism. Do LGBTQ identities, which are presumptively ‘Western’ come to colonize other local cultures? Does the use of the idea of ‘queer’ constitute an infelicitous Western imposition onto other cultures? In this study, I challenge some of the nativist responses to these questions by problematizing territorial claims of ‘Asian values’ and so-called ‘Western’ queer sexualities by showing the cultural infelicities and hybriding moorings in both. The article does so by examining a public debate that exploded in the Vietnamese print media in the late 1920s over the phenomenon of amorous relations between primarily male youth in the then newly emerging French-Vietnamese secondary schools. Based on this archive, the study maintains that same-sex sexuality foregrounds the dynamic practices of cross-cultural translation from East Asia and France, reflecting both the anxieties and aspirations of the interlocutors. Belonging neither solely to Eastern nor Western cultures, the phenomenon reveals its fundamental cultural impurity. In so doing, the archive brings into high relief the constructed artifice of Vietnamese nationalist ‘tradition’ and the ‘foreigness’ of queer sexuality.

description: Motivated by the experimental transport of a trap with a quantum mechanical system modeled as a harmonic oscillator (h.o.) the corresponding classical problem is investigated. Protocols for the fastest possible transport of a classical h.o. in a wagon over a distance d are derived where both initially and finally the wagon is at rest and the h.o. is in its equilibrium position and also at rest. The acceleration of the wagon is assumed to be bounded. For fixed oscillator frequency Ωit is shown that there are in general three switches in the acceleration and for special values of Ωonly one switch. In the latter case the optimal transport time is T_abs , that of a wagon without oscillator. The optimal transport time and the switch times are determined. It is shown that in some cases it is advantageous to go backwards for a while. In addition a time-dependent Ω(t), bounded by Ω_ and Ω+ , is allowed. In this case the behavior depends sensitively on Ω_+ and is spelled out in detail. In particular, depending on Ω_+ , T_abs may be obtained in continuously many ways.

Acquisition of Double-Nominative Constructions by Italian L1 Learners of Chinese
Creators: name: Morbiato, Anna
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2020

description:

This paper presents new results of an ongoing cross-sectional corpus study investigating the acquisition of Chinese word order by Italian L1 learners. Specifically, it focuses on the acquisition of ‘double-nominative constructions’, as well as the correct sequential organisation of topical and focal information in the Chinese sentence. The analysis is conducted on three learner corpora, created by the Author on the basis of a test submitted to three groups of university (BA and MA)-level Italian L1 learners of Chinese, for a total of 132 learners. Quantitative and qualitative analysis conducted on the collected data show that, while the double-subject construction may appear as a simple and straightforward pattern, it is in fact a rather difficult construction to acquire and spontaneously produce for Italian L1 learners. Rather, students tend to use patterns they are used to in their L1 (or other L2s, such as English). These include the [NP1 have NP2], [NP1 的 NP2], or [NP1 adjectival predicate] patterns, among other types, thus confirming the inhibitive L1 transfer hypotheses of this study.

description: Detailed investigations of structural, magnetic and electronic transport properties of hole-doped high-entropy rare-earth manganites are presented. The high-entropy samples (LaNdPrSmEu)$_{1-x}$Sr$_x$MnO$_3$ (0$\leq$\textit{x}$\leq$0.5), synthesized using the solid-state technique, show a change in the crystal structure from \textit{Pbnm} to \textit{R-3c} with increasing Sr substitution, attributed to the change in the tolerance factor. Prominent ferromagnetic ordering is observed in the sample with a rhombohedral structure (\textit{x}$\geq$0.3), originating from the dominant double exchange mechanism mediated by itinerant electrons. Further, the Curie temperature is smaller for the high-entropy sample with \textit{x}=0.3, as compared to La$_{0.7}$Sr$_{0.3}$MnO$_3$, suggesting a strong relation between the Curie temperature and the Mn-O-Mn bond angle associated with the reduced ionic radii at the rare-earth site. The electrical resistivity of the high-entropy samples is larger than those of La$_{1-x}$Sr$_x$MnO$_3$, which can be ascribed to the reduced bandwidth due to the enhanced structural distortion. A concomitant rise in magnetoresistance is observed for high-entropy samples with the increase in Sr concentration. These findings considering the configurational complexity of different rare-earths advance the understanding of high-entropy rare earth manganites.

description: To date, more than 750 planets have been discovered orbiting stars other than the Sun. Two sub-classes of these exoplanets, "hot Jupiters" and their less massive counterparts "hot Neptunes," provide a unique opportunity to study the extended atmospheres of planets outside of our solar system. We describe here the first far-ultraviolet transit study of a hot Neptune, specifically GJ436b, for which we use HST/STIS Lyman-$α$ spectra to measure stellar flux as a function of time, observing variations due to absorption from the planetary atmosphere during transit. This analysis permits us to derive information about atmospheric extent, mass-loss rate from the planet, and interactions between the star and planet. We observe an evolution of the Lyman-$α$ lightcurve with a transit depth of GJ436b from $8.8\pm4.5\%$ near mid-transit, to $22.9\pm3.9\%$ $\sim2$ hours after the nominal geometric egress of the planet. Using data from the time-tag mode and considering astrophysical noise from stellar variability, we calculate a post-egress occultation of $23.7\pm4.5\%$, demonstrating that the signature is statistically significant and of greater amplitude than can be attributed to stellar fluctuations alone. The extended egress absorption indicates the probable existence of a comet-like tail trailing the exoplanet. We calculate a mass-loss rate for GJ436b in the range of $3.7\times10^6 -1.1\times10^{9}$ g s$^{-1}$, corresponding to an atmospheric lifetime of $4\times10^{11}-2\times10^{14}$ years.

description:

As a sub-type of Chinese idioms, chengyu 成语 play an important role in Chinese teaching. This study tested the effectiveness of etymological elaboration in relation to the type of instruction (direct or indirect), the degree of transparency of the chengyu, and the participants’ proficiency level. 48 post-elementary and 53 pre-intermediate learners were divided into three groups, one control and two experimental groups. The experimental groups attended to a 30-minute treatment, then a post-test was submitted to all the participants. Statistical and qualitative analysis revealed that indirect instruction was significantly more effective than direct instruction, independently from the participants’ competence level, and that opaque chengyu were more easily retained than transparent chengyu.

description: Agriculture is one of the most important sources for human food throughout the history of humankind. In many countries, agriculture is the foundation of its economy, and more than 90% of its population deriving their livelihoods from it. Insect pests are one of the main factors affecting agricultural crop production. With the advances of computer algorithms and artificial intelligence, accurate and speedy recognition of insect pests in early stages may help in avoiding economic losses in short and long term. In this paper, an insect pest recognition based on deep transfer learning models will be presented. The IP102 insect pest dataset was selected in this research. The IP102 dataset consists of 27500 images and contains 102 classes of insect pests, it is considered one the biggest dataset for insect pest and was launched in 2019. Through the paper, AlexNet, GoogleNet, and SqueezNet were the selected deep transfer learning models. Those models were selected based on their small number of layers on their architectures, which will reflect in reducing the complexity of the models and the consumed memory and time. Data augmentation techniques were used to render the models more robust and to overcome the overfitting problem by increasing the dataset images up to 4 times than original images. The testing accuracy and performance metrics, such as the precision, recall, and F1 score, were calculated to prove the robustness of the selected models. The AlexNet model achieved the highest testing accuracy at 89.33%. In addition, it has a minimum number of layers, which decreases the training time and computational complexity. Moreover, the choice of data augmentation techniques played an important role in achieving better results. Finally, A comparison results were carried out at the end of the research with related work which used the same dataset IP102. The presented work achieved a superior result than the related work in terms of testing accuracy, precision, recall, and F1 score.
New physics in $B \to K^* τ^+ τ^-$: A model independent analysis

description: In this work we consider the implications of current $b \to s \ell^+ \ell^-$ ($\ell=e,\,μ$) measurements on several $B \to K^* τ^+ τ^-$ observables under the assumption that the possible new physics can have both universal as well as nonuniversal couplings to leptons. For new physics solutions which provide a good fit to all $b \to s \ell^+ \ell^-$ data, we intend to identify observables with large deviations from the Standard Model (SM) predictions as well as to discriminate between various new physics solutions. For this we consider the $B \to K^* τ^+ τ^-$ branching fraction, the $K^*$ longitudinal fraction $f_L$, the tau forward-backward asymmetry $A_{FB}$ and the optimized observables in the $P_i^{(')}$ basis. Further, we construct the $τ- μ$ lepton-flavor differences ($Q^{τμ}$) between these tau observables and their muonic counterparts in $B \to K^* μ^+ μ^-$ decay. Moreover, we also consider lepton-flavor ratios ($R^{τμ}$) of all of these observables. We find that the current data allows for deviations ranging from 25% up to an order of magnitude from the SM value in a number of observables. For e.g., the magnitudes of $Q^{τμ}_{P_3}$ and $Q^{τμ}_{P'_8}$ observables can be enhanced up to an order of magnitude, a twofold enhancement in $Q^{τμ}_{A_{FB}}$ is possible along with $\sim$50% enhancement in $R^{τμ}_{K^*}$ and $\sim$25% in $R^{τμ}_{A_{FB}}$. Moreover, the branching ratio of $B \to K^* τ^+ τ^-$ can be suppressed up to 25%. A precise measurement of these observables can also discriminate between a number of new physics solutions.

Wreckage, War, Woman. Fragments of a Female Self in Zhang Ailing’s Love In a Fallen City (倾城之恋)
Creators: name: Di Muzio, Alessandra
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2020

description:

This article examines wreckage and war as key elements in Zhang Ailing’s novella Qing cheng zhi lian 倾城之恋 (Love in a Fallen City) exploring the strategies used by the female protagonist to engage on a nüxing 女性 ‘feminist’-oriented spatial quest for independence in a male-centered world. Analysed from a feminist perspective, these strategies emerge as potentially empowering and based on the idea of conflict/conquest while dealing with man and romance, but they are also constantly threatened by the instability of history and by the lack of any true agency and gender-specific space for women in the 1940s Chinese society and culture. By analysing the floating/stability dichotomy and the spatial configurations of Shanghai and Hong Kong as described in the novella, the author argues Zhang Ailing’s depiction of Chinese women while dealing with history, society and the quest for self-affirmation is left in-between wreckage and survival, oppression and feminism, revealing her eccentric otherness as a woman and as a writer with respect to socially committed literature.

description: Skin cancer is the most common type of cancer. One in every three cancers diagnosed is a skin cancer according to skin cancer foundation statistics globally. The early detection of this type of cancer would help in raising the opportunities of curing it. The advances in computer algorithms such as deep learning would help doctors to detect and diagnose skin cancer automatically in early stages. This paper introduces an empirical study and enhancement on deep transfer learning for skin lesions detection. The study selects different pre-trained deep convolutional neural network models such as resnet18, squeezenet, google net, vgg16, and vgg19 to be applied into two different datasets. The datasets are MODE-NODE and ISIC skin lesion datasets. Data augmentation techniques have been adopted in this study to enlarge the total number of images in the datasets to be 5 times larger than the original datasets. The adopted augmentation techniques make the DCNN models more robust and prevent overfitting. Moreover, seven accredited performance matrices in deep learning have been used to conclude an optimal selection of the most appropriate DCNN model that fits the nature of the skin lesions datasets. The study concludes that vgg19 is the most appropriate DCNN according to testing accuracy measurement and achieved 98.8%. The seven performance matrices strengthen this result. Also, a comparative result was introduced with related works. The vgg19 overcomes the related work in terms of testing accuracy and the performance matrices on both datasets. Finally, the vgg19 model was trained on a smaller number of images than the related work by 10 times, which proved that the choice of data augmentation techniques played an important role in achieving better results. That would reflect on reducing the training time, memory consumption and the calculation complexity.

description: We evaluate the model averaged profile likelihood confidence intervals proposed by Fletcher and Turek (2011) in a simple situation in which there are two linear regression models over which we average. We obtain exact expressions for the coverage and the scaled expected length of the intervals and use these to compute these quantities in particular situations. We show that the Fletcher-Turek confidence intervals can have coverage well below the nominal coverage and expected length greater than that of the standard confidence interval with coverage equal to the same minimum coverage. In these situations, the Fletcher-Turek confidence intervals are unfortunately not better than the standard confidence interval used after model selection but ignoring the model selection process.
Ah Q Travels to Europe

Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia

description:

This study focuses on the adaptations of the novella “The True Story of Ah Q” by the Chinese writer Lu Xun (1881-1936), produced by two important European playwrights, Christoph Hein (b. 1944) and Dario Fo (1926-2016), who ‘translated’ Lu Xun’s famous character respectively into a problematic nihilist (Die wahre Geschichte des Ah Q, 1983) and into a revolutionary Chinese Harlequin (La storia di Qu, 1989; 2011). These two plays appropriate the ‘hypotext’ into a new cultural geography, which is neither Chinese nor completely German or Italian, but rather a transcultural space based on the European intellectual tradition of the ‘anarchist’. In this case translation means a thorough transformation and change which allows Lu Xun’s work to ‘live on’ (Fortleben, as in Walter Benjamin’s theory).

description: We report the implementation of a multi-CPU and multi-GPU massively parallel platform dedicated to the explicit inclusion of nuclear quantum effects (NQEs) in the Tinker-HP molecular dynamics (MD) package. The platform, denoted Quantum-HP, exploits two simulation strategies: the Ring-Polymer Molecular Dynamics (RPMD) that provides exact structural properties at the cost of a MD simulation in an extended space of multiple replicas, and the adaptive Quantum Thermal Bath (adQTB) that imposes the quantum distribution of energy on a classical system via a generalized Langevin thermostat and provides computationally affordable and accurate (though approximate) NQEs. We discuss some implementation details, efficient numerical schemes, parallelization strategies and quickly review the GPU acceleration of our code. Our implementation allows an efficient inclusion of NQEs in MD simulations for very large systems, as demonstrated by scaling tests on water boxes with more than 200,000 atoms (simulated using the AMOEBA polarizable force field). We test the compatibility of the approach with Tinker-HP's recently introduced Deep-HP machine learning potentials module by computing water properties using the DeePMD potential with adQTB thermostating. Finally, we show that the platform is also compatible with the alchemical free energy estimation capabilities of Tinker-HP and fast enough to perform simulations. Therefore, we study how the NQEs affect the hydration free energy of small molecules solvated with the recently developed Q-AMOEBA water force field. Overall, the Quantum-HP platform allows users to perform routine quantum MD simulations of large condensed-phase systems and will participate to shed a new light on the quantum nature of important interactions in biological matter.
