description: From a geometric point of view, we show that the unitary symmetries $U(1)$ and $SU(2)$ stem fundamentally from Schwarzschild and Reissner-Nordström wormhole geometry through spacetime complexification. Then, we develop quantum tunneling which makes these wormholes traversable for particles. Finally, this leads to wormhole thermodynamics.

A revised thermonuclear rate of $^{7}$Be($n$,$α$)$^{4}$He relevant to Big-Bang nucleosynthesis

description: In the standard Big-Bang nucleosynthesis (BBN) model, the primordial $^7$Li abundance is overestimated by about a factor of 2--3 comparing to the astronomical observations, so called the pending cosmological lithium problem. The $^7$Be($n$,$α$)$^4$He reaction, which may affect the $^7$Li abundance, was regarded as the secondary important reaction in destructing the $^7$Be nucleus in BBN. However, the thermonuclear rate of $^7$Be($n$,$α$)$^4$He has not been well studied so far. This reaction rate was firstly estimated by Wagoner in 1969, which has been generally adopted in the current BBN simulations and the reaction rate library. This simple estimation involved only a direct-capture reaction mechanism, but the resonant contribution should be also considered according to the later experimental results. In this work, we have revised this rate based on the indirect cross-section data available for the $^4$He($α$,$n$)$^7$Be and $^4$He($α$,$p$)$^7$Li reactions, with the charge symmetry and detailed-balance principle. Our new result shows that the previous rate (acting as an upper limit) is overestimated by about a factor of ten. The BBN simulation shows that the present rate leads to a 1.2\% increase in the final $^7$Li abundance compared to the result using the Wagoner rate, and hence the present rate even worsens the $^7$Li problem. By the present estimation, the role of $^7$Be($n$,$α$)$^4$He in destroying $^7$Be is weakened from the secondary importance to the third, and the $^7$Be($d$,$p$)2$^4$He reaction becomes of secondary importance in destructing $^7$Be.

subject: Cyberphysical systems and internet of things

description: This research investigated the impact of the Internet of Things (IoT) on the embodied experience of architecture. A new concept, Disseminating Embodiment, was mooted for expanding and contracting embodied engagements across local and global digitalised built environments. This shared body is a cinematic experience through the interactive IoT involving cameras, sensors, actuators, and processors, as well as digital memory and playback.The writings of philosophers Henri Bergson and Gilles Deleuze served as primary texts on body, cinema, technology, and time for this research. Their ontological arguments for the actualisation of new conditions informed this new concept of human embodiment for 21st century digital experiences.Through the professional practice, academic experimentations, and case studies of this research, subjective identities were conceptualised to differentiate throughout Disseminating Embodiment. Some of these emerge as already human, termed Anthropomorphic Durée. The manifesto genre was researched in order to proclaim the new Anthropomorphic Durée Manifesto that fosters open protocols for human agency. This Manifesto, offering ten tenets or Architectural Expressions, provides a theoretical and practical tool to address 21st century hopes and concerns regarding life with and through the IoT.

Additive manufacturing

description: Metal additive manufacturing (or 3D printing) is a technology for printing complex parts for the biomedical and aerospace industry. Currently, it is employed only in niche applications, and wider adoption of this technology is challenged by both high cost and quality assurance issues. However, with the rise of digital technologies and artificial intelligence, new solutions are emerging. This thesis explores how digital twin technology can improve the complex 3D printing process and manufacture parts that are cheaper to make, more reliable, and stronger.

description: In this paper, we investigate the effect of atomic collisions on the phase transition form the normal to the superradiant phase in a one-dimensional Bose-Einstein condensate (BEC) trapped inside an optical cavity. Specifically, we show that driving the atoms from the side of the cavity leads to the excitation of modes in the edges of the first Brillouin zone of every energy band, which results in the two-mode approximation of the BEC matter field in the limit of weak coupling regime. The nonlinear effect of atom-atom interaction shifts the threshold of the quantum phase transition of the BEC and also affect the power low behavior of quantum fluctuations in the total particle number. Besides, we show the possibility of controlling the quantum phase transition of the system through the s-wave scattering frequency when the the strength of the transverse pumping has been fixed.

description: Despite increased awareness and efforts to reduce buffer overflows, they continue to be the cause of most software vulnerabilities. In large part, these problems are due to the widespread use of unsafe library routines among programmers. For reasons like efficiency, such routines will continue to be used, even during the development of mission-critical and safety-critical software systems. Effective certification techniques are needed to ascertain whether unsafe routines are used in a safe manner.

This report presents a technique for certifying the safety of buffer manipulations in C programs. The approach is based on two key ideas: (1) using a certifying model checker to automatically verify that a buffer manipulation is safe and (2) validating the resulting invariant and proving it with a decision procedure based on Boolean satisfiability. This report also discusses the advantages and limitations of the approach with respect to today's existing solutions for buffer-overflow detection. Experimental results are presented that position the technique favorably against other static overflow-detection tools and indicate that the procedure can complement and augment these tools from a purely verification perspective.

description: Efficient similarity retrieval from large-scale multimodal database is pervasive in modern search engines and social networks. To support queries across content modalities, the system should enable cross-modal correlation and computation-efficient indexing. While hashing methods have shown great potential in achieving this goal, current attempts generally fail to learn isomorphic hash codes in a seamless scheme, that is, they embed multiple modalities in a continuous isomorphic space and separately threshold embeddings into binary codes, which incurs substantial loss of retrieval accuracy. In this paper, we approach seamless multimodal hashing by proposing a novel Composite Correlation Quantization (CCQ) model. Specifically, CCQ jointly finds correlation-maximal mappings that transform different modalities into isomorphic latent space, and learns composite quantizers that convert the isomorphic latent features into compact binary codes. An optimization framework is devised to preserve both intra-modal similarity and inter-modal correlation through minimizing both reconstruction and quantization errors, which can be trained from both paired and partially paired data in linear time. A comprehensive set of experiments clearly show the superior effectiveness and efficiency of CCQ against the state of the art hashing methods for both unimodal and cross-modal retrieval.

description: We present a study of the variation of total energies and excitationenergies along a range-separated adiabatic connection. This connectionlinks the non-interacting Kohn-Sham electronic system to the physicalinteracting system by progressively switching on theelectron-electron interactions whilst simultaneously adjusting aone-electron effective potential so as to keep the ground-statedensity constant. The interactions are introduced in arange-dependent manner, first introducing predominantly long-range,and then all-range, interactions as the physical system is approached,as opposed to the conventional adiabatic connection where theinteractions are introduced by globally scaling the standard Coulomb interaction.Reference data are reported for the He and Be atoms and the H2molecule, obtained by calculating the short-range effective potentialat the full configuration-interaction level using Lieb'sLegendre-transform approach. As the strength of the electron-electroninteractions increases, the excitation energies, calculated for thepartially interacting systems along the adiabatic connection, offerincreasingly accurate approximations to the exact excitation energies.Importantly, the excitation energies calculated at an intermediatepoint of the adiabatic connection are much better approximations tothe exact excitation energies than are the corresponding Kohn-Shamexcitation energies. This is particularly evident in situationsinvolving strong static correlation effects and states with multipleexcitation character, such as the dissociating H2 molecule. Theseresults highlight the utility of long-range interacting referencesystems as a starting point for the calculation of excitation energiesand are of interest for developing and analyzing practical approximaterange-separated density-functional methodologies.

title:  Let’s Go for New or Emerging Security Technologies! … What About Their Impact on Individuals and the Society?
Creators: name: Bonfanti, Matteo
Publisher: name: Roma TrE-Press
Year: 2017

description: Technological innovation is embraced as an unquestionable component of the EU’s security policies which promote the development and employment of “new”, “advanced”, “next generation” or “emerging” technologies for countering security threats. The same policies call also for the assessment of the impact emerging technological tools may have on individuals’ values, their fundamental rights, and the society as a whole.

With regard to technologies that are “emerging”, this assessment should occour at R&D stage, and aim at establishing the likely effects the technologies may have on the above values, rights, and the society. It should estimate to what extent their potential employment comply with the principles of a democratic society and the rule of law. As such, it is a very wide‐ranging and complex form of investigation. The proposed paper examines the benefits stemming from an ex‐ante impact assessment of emerging technologies for security. It argues that anticipatory thinking on ethical, fundamental rights and societal implications of emerging technologies is paramount to identify and mitigate possible negative effects as well as fully exploit all the benefits the concerned technologies may generate. It then discusses a methodology for investigating the ethical, fundamental rights and societal implications generated by the adoption of emerging technological solutions.

description: People responsible for computer security incident response and digital forensic examination need to continually update their skills, tools, and knowledge to keep pace with changing technology. No longer able to simply unplug a computer and evaluate it later, examiners must know how to capture an image of the running memory and perform volatile memory analysis using various tools, such as PsList, ListDLLs, Handle, Netstat, FPort, Userdump, Strings, and PSLoggedOn. This paper presents a live response scenario and compares various approaches and tools used to capture and analyze evidence from computer memory.

description: We present recent evolutions of the detailed opacity code SCO-RCG which combines statistical modelings of levels and lines with fine-structure calculations. The code now includes the Partially-Resolved-Transition-Array model, which allows one to replace a complex transition array by a small-scale detailed calculation preserving energy and variance of the genuine transition array and yielding improved high-order moments. An approximate method for studying the impact of strong magnetic field on opacity and emissivity was also recently implemented. The Zeeman line profile is modeled by fourth-order Gram-Charlier expansion series, which is a Gaussian multiplied by a linear combination of Hermite polynomials. Electron collisional line broadening is often modeled by a Lorentzian function and one has to calculate the convolution of a Lorentzian with Gram-Charlier distribution for a huge number of spectral lines. Since the numerical cost of the direct convolution would be prohibitive, we propose, in order to obtain the resulting profile, a fast and precise algorithm, relying on a representation of the Gaussian by cubic splines.

description: The most important parameters in the study of low-energy scattering are the s-wave and p-wave scattering lengths and the s-wave effective range. We solve the scattering problem and find two useful formulas for the scattering length and the effective range for any angular momentum, as long as the Wigner threshold law holds. Using that formalism, we obtain a set of useful formulas for the angular-momentum scattering parameters of four different model potentials: hard-sphere, soft-sphere, spherical well, and well-barrier potentials. The behavior of the scattering parameters close to Feshbach resonances is also analyzed. Our derivations can be useful as hands-on activities for learning scattering theory.

description: We present an observational and dynamical study of newly discovered main-belt comet 313P/Gibbs. We find that the object is clearly active both in observations obtained in 2014 and in precovery observations obtained in 2003 by the Sloan Digital Sky Survey, strongly suggesting that its activity is sublimation-driven. This conclusion is supported by a photometric analysis showing an increase in the total brightness of the comet over the 2014 observing period, and dust modeling results showing that the dust emission persists over at least three months during both active periods, where we find start dates for emission no later than 2003 July 24+/-10 for the 2003 active period and 2014 July 28+/-10 for the 2014 active period. From serendipitous observations by the Subaru Telescope in 2004 when the object was apparently inactive, we estimate that the nucleus has an absolute R-band magnitude of H_R=17.1+/-0.3, corresponding to an effective nucleus radius of r_e~1.00+/-0.15 km. The object's faintness at that time means we cannot rule out the presence of activity, and so this computed radius should be considered an upper limit. We find that 313P's orbit is intrinsically chaotic, having a Lyapunov time of T_l=12000 yr and being located near two 3-body mean-motion resonances with Jupiter and Saturn, 11J-1S-5A and 10J+12S-7A, yet appears stable over >50 Myr in an apparent example of stable chaos. We furthermore find that 313P is the second main-belt comet, after P/2012 T1 (PANSTARRS), to belong to the ~155 Myr old Lixiaohua asteroid family.

description: The fundamental agreement between the Holy See and Israel, signed on December 30, 1993, is part of a historical, political, social, cultural, religious and international diplomatic context that mainly concerns the question of the Holy Places, difficult to resolve, and remained unresolved from the Crusades, and the relations between Jews and Christians.
But the Agreement also demonstrates that the Middle Eastern Holy Seeʹs policy overrides the regional boundaries of this geographical area, assuming a global dimension not so much, and not only geographically, but in terms of relations with Islamic politics and the Jewish policy of the Catholic Church through interreligious dialogue, which implies «un delicato lavoro teologico di interpretazione dei testi sacri in modo che consenta di trascendere la violenza che essi frequentemente contengono; richiede un’attenta riconsiderazione della dignità che deve essere riconosciuta all’‘altro’, l’infedele o il fedele di un’altra religione; esige una teologia politica che sappia guardare con simpatia alla laicità dello Stato e della società civile» (Ferrari, 2005, 184).

description: This report describes efforts by the Software Engineering Institute (SEI) to increase the capacity of institutions of higher education to offer information assurance (IA) and information security (IS) courses, to expand existing IA and IS offerings, and to include IA and IS topics and perspectives, as appropriate, in other courses.

To accomplish these goals, the SEI transitions courseware, materials, and a survivability and information assurance curriculum to various departments at institutions of higher education, participates in NSF-funded faculty capacity-building programs, creates partnerships with key regional educational institutions, and offers IA symposia, among other efforts. While the SEI works with all institutions of higher education, there is a particular focus on minority-serving institutions.

Rather than build a new infrastructure to accomplish this, the SEI utilizes partnerships that leverage the strengths of the SEI and the strengths of the partner educational institutions and builds upon existing trusted relationships and infrastructure, and sustains the incorporation of new and evolving materials. Leveraging other complementary programs, events, and organizations broadens the offering and makes it more cost effective to all parties concerned.

description: In this paper we are concerned with multiscale modeling, control, and simulation of self-organizing agents leaving an unknown area under limited visibility, with special emphasis on crowds. We first introduce a new microscopic model characterized by an exploration phase and an evacuation phase. The main ingredients of the model are an alignment term, accounting for the herding effect typical of uncertain behavior, and a random walk, accounting for the need to explore the environment under limited visibility. We consider both metrical and topological interactions. Moreover, a few special agents, the leaders, not recognized as such by the crowd, are "hidden" in the crowd with a special controlled dynamics. Next, relying on a Boltzmann approach, we derive a mesoscopic model for a continuum density of followers, coupled with a microscopic description for the leaders' dynamics. Finally, optimal control of the crowd is studied. It is assumed that leaders exploit the herding effect in order to steer the crowd towards the exits and reduce clogging. Locally-optimal behavior of leaders is computed. Numerical simulations show the efficiency of the optimization methods in both microscopic and mesoscopic settings. We also perform a real experiment with people to study the feasibility of the proposed bottom-up crowd control technique.

description: Numerical modeling of the intensity and evolution of flood events are affected by multiple sources of uncertainty such as precipitation and land surface conditions. To quantify and curb these uncertainties, an ensemble-based simulation and data assimilation model for pluvial flood inundation is constructed. The shallow water equation is decoupled in the x and y directions, and the inertial form of the Saint-Venant equation is chosen to realize fast computation. The probability distribution of the input and output factors is described using Monte Carlo samples. Subsequently, a particle filter is incorporated to enable the assimilation of hydrological observations and improve prediction accuracy. To achieve high-resolution, real-time ensemble simulation, heterogeneous computing technologies based on CUDA (compute unified device architecture) and a distributed storage multi-GPU (graphics processing unit) system are used. Multiple optimization skills are employed to ensure the parallel efficiency and scalability of the simulation program. Taking an urban area of Fuzhou, China as an example, a model with a 3-m spatial resolution and 4.0 million units is constructed, and 8 Tesla P100 GPUs are used for the parallel calculation of 96 model instances. Under these settings, the ensemble simulation of a 1-hour hydraulic process takes 2.0 minutes, which achieves a 2680 estimated speedup compared with a single-thread run on CPU. The calculation results indicate that the particle filter method effectively constrains simulation uncertainty while providing the confidence intervals of key hydrological elements such as streamflow, submerged area, and submerged water depth. The presented approaches show promising capabilities in handling the uncertainties in flood modeling as well as enhancing prediction efficiency.

description: We report on experimental observation of BEC-like behaviour of quantized electron spin waves (magnons) in a dense gas of spin polarized atomic hydrogen. The magnons are trapped and controlled with inhomogeneous magnetic fields, and described by a Schrödinger-like wave equation, in analogy to the BEC experiments with neutral atoms. We have observed the appearance of a sharp feature in the ESR spectrum displaced from the normal spin wave spectrum. We believe that this observation corresponds to a sudden growth of the ground state population of the magnons and emergence of their spontaneous coherence for hydrogen gas densities exceeding a critical value, dependent on the trapping potential. We interpret the results as a BEC of non-equilibrium magnons which were formed by applying the rf power.

description: Memes have gained popularity as a means to share visual ideas through the Internet and social media by mixing text, images and videos, often for humorous purposes. Research enabling automated analysis of memes has gained attention in recent years, including among others the task of classifying the emotion expressed in memes. In this paper, we propose a novel model, cluster-based deep ensemble learning (CDEL), for emotion classification in memes. CDEL is a hybrid model that leverages the benefits of a deep learning model in combination with a clustering algorithm, which enhances the model with additional information after clustering memes with similar facial features. We evaluate the performance of CDEL on a benchmark dataset for emotion classification, proving its effectiveness by outperforming a wide range of baseline models and achieving state-of-the-art performance. Further evaluation through ablated models demonstrates the effectiveness of the different components of CDEL.

This implies the need to identify a priori appropriate bodies to approve the state of siege and involves the logical corollary to define the official and substantial limits, within which the (temporary) suspension of fundamental human rights can possibly be arranged, in order to find the right balance including the need to preserve the immanence of free institutions, without, at the same time disclaiming and / or mortifying the axiological foundations on which they themselves are ruled, in view of the affirmation of a political/constitutional settlement directed to the sense of protection and promotion (even towards enemies) of the individual’s inviolable rights.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: In this paper a toy model of quantum topology is reviewed to study effects of matter and gauge fields on the topology fluctuations. In the model a collection of N one dimensional manifolds are considered where a set of boundary conditions on states of Hilbert space specifies a set of all topologies perceived by quantum particle and probability of having a specific topology is determined by a partition function over all the topologies in the context of noncommutative spectral geometry. In general the topologies will be fuzzy with the exception of a particular case which is localized by imposing a specific boundary condition. Here fermions and bosons are added to the model. It is shown that in the presence of matter, the fuzziness of topology will be dependent on N, however for large N the dependence is removed similar to the case without matter. Also turning on a particular background gauge field, can overcome the fuzziness of topology to reach a localized topology with classical interpretation. It can be seen that for large N more opportunities can be provided for choosing the background gauge field to localize the fuzzy topology.
title:  In the Fight Against Terrorism, Does Article 15 of the ECHR Constitute an Effective Limitation to States’ Power to Derogate From Their Human Rights Obligations?

description: This paper will focus on Article 15 of the European Convention on Human Rights (ECHR), which allows national authorities to declare a state of emergency and, consequently, to derogate from certain human rights obligations. It is worth observing that it is in time of emergency that there is a greater risk for human rights violation, due to the possible abuse of powers by states. For this reason, it will be illustrated which rights can be derogated from and when a derogation is deemed to be valid in the light of Article 15 ECHR. The case‐law of the European Court will show that only on very few occasions states have relied on this provision. However, when the derogation power has been invoked, the Court has given a wide margin of appreciation to contracting states when assessing the compliance with the requirements under Article 15.
This approach has been criticised for being too deferential and for weakening the Court’s authoritative position vis‐à‐vis national governments. Although Article 15 ECHR should limit states’ right to derogate, in practice the wide discretion left to them nullifies the effectiveness of this provision.

description: Machine learning is changing how researchers interact with scholarly literature. While it has the potential to reveal exciting new connections between areas of study, popular commercial tools that provide recommendations to users based on personalized profiles developed with machine learning can negatively impact the breadth of sources they will discover. Over time, they may even limit the questions researchers are willing to explore. Find out what machine learning is and how it is being deployed to make the literature more manageable, then learn strategies to warn users about its pitfalls and advocate for the responsible use of this technology.

description: Developing and implementing measurable methodologies for improving the security and resilience of a national postal sector directly contribute to protecting public and postal personnel, assets, and revenues. Such methodologies also contribute to the security and resilience of the mode of transport used to carry mail and the protection of the global mail supply chain. Since 2011, the U.S. Postal Inspection Service (USPIS) has collaborated with the CERT Division at Carnegie Mellon University’s Software Engineering Institute to improve the resilience of selected U.S. Postal Service (USPS) products and services. The CERT Resilience Management Model (CERT-RMM) and its companion diagnostic methods served as the foundational tool for this collaboration.
This report includes one result of the USPIS/CERT collaboration. It is an extension of CERT-RMM to include a new mail-specific process area for the transportation of international mail. The purpose is to ensure that all international mail is transported in accordance with the standards established by the Universal Postal Union (UPU), which is the governing body that regulates the transportation of international mail.
title: Nanovibrational stimulation for 3D osteogenesis in biphasic 3D scaffold; a new option for bone tissue engineering

description: In our centre, we had developed nanovibrational bioreactor generating nanoscale vibration by piezo actuator for bone tissue engineering. Recently, nanovibrational stimulation (NS; 30 nm at 1000 Hz) showed the success of osteogenic induction in mesenchymal stem cells (MSCs) seeded collagen hydrogel without chemical supplement. However, culturing MSCs in the collagen hydrogel for long term NS stimulation in NS bioreactor is challenging due to its mechanical properties. The principle aim of this thesis is to develop the scaffold for nanovibrational bioreactor which is suitable for surgical application. Three strategies including ingel scaffolds, collagen concentration optimization and genipin crosslinking were trialled which aimed to improve hydrogel stiffness and handleability, possess biocompatibility and allow NS force transmission. The role of high amplitude stimulation (90 nm at 1000 Hz) on 3D osteogenesis was also studied. Interestingly, increasing NS amplitude successfully enhanced 3D osteogenesis through multiple pathways and it was biologically safe. Metabolomics during NS revealed the evidence of low level of reactive oxygen species production and inflammation which was controlled in physiological level through multiple intracellular signals such as redox balancing, NFkB and MAPK pathways. To propose the technique how to use NS induced MSCs for clinics, MSCs seeded biphasic scaffolds compositing collagen hydrogels and freeze dried collagen sponges were developed. Cell-hydrogel-sponge composite (CHSC) was reproducible, handleable and biologically safe. CHSC allowed a good fidelity of NS. NS with high amplitude stimulation successfully induced 3D osteogenesis. NS protocol in CHSC was optimized in order to identify a stimulating duration which can induce osteogenesis without phenotypic reversibility. Interestingly, two-week stimulation possibly committed MSCs in the preosteoblast stage.
title:  L’esperienza spagnola: dal terrorismo interno alla minaccia globale. Strumenti di difesa di una democrazia “banco di prova”

description: The Spanish System represents a minor reality in a context in which Western European Democracies have opted to exclude from their Constitutions the preventive provision of the so‐called state of emergency and the specific case of terrorism. After all, the events that affected Spain are well‐known. Since many years, Spain has been active in the conflict against the Basque Terrorism and the democratic dilemmas, because of the presence in the Parliament of parties linked to the terrorist group Eta. And exactly the well‐known Ley organic sobre los partidos políticos 6/2002, which outlawed the Batasuna Party and other political organizations connected to the Eta group.
Therefore, in the Spanish System the article 55, II clause, as well as the legislation related to the political parties tagged as anti‐system, represent the fundamental profiles of peculiarity in the field of anti‐terrorism legislation. Nevertheless, through this article we will try to demonstrate that the distinctive characteristic in the Spanish discipline does not lie on the provision of extraordinary measures in the Constitution. Instead, the main point is that this phenomenon has been disciplined by a legislation deliberately “fabricated” for a specific subject: Eta.

description: How we perceptually organize a visual stimulus depends not only on the stimulus itself, but also on the temporal and spatial context in which the stimulus is presented as well as on the individual processing the stimulus and context. Earlier research found both attractive and repulsive context effects in perception (Snyder, Schwiedrzik, Vitela, & Melloni, 2015): tendencies to organize visual input in a similar way as preceding or simultaneous context stimuli (i.e., hysteresis, attraction) co-exist with tendencies that repel or move away the current percept from the organization that is most dominant in these contextual stimuli (i.e., adaptation, repulsion). These processes have been studied mostly on a group level (e.g., Schwiedrzik et al., 2014). The present study will investigate whether consistent individual differences exist in these attractive and repulsive temporal context effects, using multistable dot lattices as stimuli. In addition, the relation of the strength of these effects with the strength of individual biases for absolute orientations will be investigated. In this way, the study will provide insight in how different individuals combine previous input and experience with current input in their perception, and more generally, whether different individuals can perceive identical stimuli differently even within a similar context.
