Year: 2016
Subjects: subject: Networking and Internet Architecture (cs.NI)

description: Software-Defined Networking enables the centralized orchestration of data traffic within a network. However, proposed solutions require a high degree of architectural penetration. The present study targets the orchestration of network elements that do not wish to yield much of their internal operations to an external controller. Backpressure routing principles are used for deriving flow routing rules that optimally stabilize a network, while maximizing its throughput. The elements can then accept in full, partially or reject the proposed routing rule-set. The proposed scheme requires minimal, relatively infrequent interaction with a controller, limiting its imposed workload, promoting scalability. The proposed scheme exhibits attracting network performance gains, as demonstrated by extensive simulations and proven via mathematical analysis.

description: GN-z11 is an unusually luminous high redshift galaxy which was recently observed to have strong nitrogen lines while at the same time lacking traditional signatures of AGN activity. These observations have been interpreted as a super-solar nitrogen abundance which is challenging to explain with standard stellar evolution and supernovae enrichment. We present simulations of four models of metal enriched supermassive stars after the zero age main sequence which produce super-solar nitrogen consistent with the observations of GN-z11. We then show that the most massive model ends its life in a violent explosion which results in even greater nitrogen pollution.

description: Рассмотрен процессный подход к анализу функционирования технического объекта с целью его модернизации на примере кулера для получения газированной воды. Кардинальное отличие данного подхода от классического заключается в обратной последовательности выполнения функционального анализа. Сначала определяется процесс, затем исполняемые функции, и только потом выявляются компоненты технического объекта, реализующие функции. Моделирование бизнес-процесса выполнялось с использованием нотации на основе IDEF0. Дополнительно предложено использовать матричное описание бизнес-процесса, для выявления недостатков и формулирования задач по их устранению. Цель работы: познакомить читателей с методом модернизации бизнес-процессов и технических объектов на реальном кейсе. В работе показано, как предложенный метод позволил выявить недостатки кулера, и обосновано предложить несколько направлений его совершенствования.

description: We report the discovery of a dwarf protoplanetary disk around the star XZ Tau B that shows all the features of a classical transitional disk but on a much smaller scale. The disk has been imaged with the Atacama Large Millimeter/Submillimeter Array (ALMA), revealing that its dust emission has a quite small radius of ~ 3.4 au and presents a central cavity of ~ 1.3 au in radius that we attribute to clearing by a compact system of orbiting (proto)planets. Given the very small radii involved, evolution is expected to be much faster in this disk (observable changes in a few months) than in classical disks (observable changes requiring decades) and easy to monitor with observations in the near future. From our modeling we estimate that the mass of the disk is large enough to form a compact planetary system.

description: We present the detection of an absorpton feature at $E=8.77^{+0.05}_{-0.06}$ keV in the combined X-ray spectrum of the ultraluminous X-ray source NGC 1313 X-1 observed with XMM-Newton and NuSTAR, significant at the 3$σ$ level. If associated with blueshifted ionized iron, the implied outflow velocity is ~0.2$c$ for Fe XXVI, or ~0.25$c$ for Fe XXV. These velocities are similar to the ultrafast outflow seen in absorption recently discovered in this source at lower energies by XMM-Newton, and we therefore conclude that this is an iron component to the same outflow. Photoionization modeling marginally prefers the Fe XXV solution, but in either case the outflow properties appear to be extreme, potentially supporting a super-Eddington hypothesis for NGC 1313 X-1.

description: Понятие «стратегия» является ключевым в теории управления. Стратегия это образ действий, обуславливающий вполне определенную и относительно устойчивую линию поведения объекта стратегирования на достаточно продолжительном историческом интервале. Именно поэтому практически применимые подходы и методики разработки стратегий так необходимы и востребованы для предприятий любой отрасли и сферы деятельности. Известны методы стратегического планирования, основанные на системном анализе и моделировании взаимодействия рассматриваемого объекта с внешней средой во времени. Основной недостаток этих методов состоит в том, что они не приспособлены к учету качественных изменений в рассматриваемой системе. Для учета принципиальных изменений системы при стратегическом планировании предлагается использовать инструменты ТРИЗ, в частности, прямое и обратное применение Модели ТРИЗ. Разработанный авторами метод стратегического планирования предусматривает двойственный подход: один путь планирования от решения существующих в системе проблем и противоречий, а второй обратный от путей реализации сформированного будущего образа рассматриваемой системы. Оба подхода взаимно дополняют друг друга в итерационном процессе стратегического планирования. В работе приведен обзор существующих методов планирования с выделением их сильных и слабых сторон, сравнение этих методов с помощью девяти экранной модели (системного оператора). Авторами в работе раскрывается метод и алгоритм формирования стратегических планов и приводятся практические примеры использования разработанного метода и алгоритма.

description: About 25-50% of white dwarfs (WDs) show metal lines in their spectra. Among the widely accepted explanations for this effect is that the these WDs are accreting asteroids that are perhaps flung onto the WDs by a planet via resonance, for instance. A number of theoretical works have looked into the accretion of asteroids onto WDs and obtained a fair agreement with the observed accretion rate. However, it is solely a very recent study (referenced in this work) that has taken asteroid binarity into consideration, examining the scattering between an asteroid binary and planets and showing that a dissociation and ejection of the former might result and the effect on WD metal accretion is likely to be weak. Here, we investigate the close encounter between an asteroid binary and the central WD and consider how the binary's dissociation may affect the WD's accretion. We find that depending on the orbital and physical properties, the components may acquire orbits that are significantly different (even on the order of unity) from that of the parent binary. We assumed all the inner main belt asteroids are binaries and we studied their accretion onto the solar WD under the perturbation of the giant planets. We find that compared to the case without binaries, the components' accretion may be postponed (or put forward) by millions of years or more, as the objects may be taken out of (or driven deeper into) the resonance due to the sudden orbital change upon dissociation. However, the overall influence of binary dissociation on the accretion rate is not very significant.

A Resource Efficient Implementation of the RESTCONF Protocol for OpenWrt Systems

description: In recent years, the open source operating system OpenWrt has become a popular option for replacing proprietary firmware on networking devices such as home routers or access points. In order to configure an OpenWrt system, like setting up firewall rules, the user has to either sign in to the web interface or use SSH to manually change configuration files on the device. While the current approach is sufficient for small home networks, it only allows for limited automation of management tasks and configuration management becomes time-consuming, for example, on larger campus networks where access control lists on OpenWrt access points need updates regularly. This paper describes our efforts to implement the RESTCONF configuration management protocol standardized by the IETF on OpenWrt systems that have limited CPU and memory resources. We detail our design choices that make our implementation resource efficient for the use cases we target and we compare our implementation against other similar solutions. Our implementation is available on GitHub under an open source license.

description: Non-diagonal couplings to a bosonic bath completely change polaronic dynamics, from the usual diagonally-coupled paradigm of smoothly-varying properties. We study, using analytic and numerical methods, a model having both diagonal Holstein and non-diagonal Su-Schrieffer-Heeger (SSH) couplings. The critical coupling found previously in the pure SSH model, at which the $k=0$ effective mass diverges, now becomes a transition line in the coupling constant plane - the form of the line depends on the adiabaticity parameter. Detailed results are given for the quasiparticle and ground state properties, over a wide range of couplings and adiabaticity ratios. The new paradigm involves a destabilization, at the transition line, of the simple Holstein polaron to one with a finite ground-state momentum, but with everywhere a continuously evolving band shape. No 'self-trapping transition' exists in any of these models. The physics may be understood entirely in terms of competition between different hopping terms in a simple renormalized effective band theory. The possibility of further transitions is suggested by the results.

description: The performance of full-duplex (FD) relay systems can be greatly impacted by the self-interference (SI) at relays. By exploiting multi-antenna in FD relay systems, the spectral efficiency of FD relay systems can be enhanced through spatial SI mitigation. This paper studies joint source transmit beamforming and relay processing to achieve rate maximization for FD MIMO amplify-and-forward (AF) relay systems with consideration of relay processing delay. The problem is difficult to solve due mainly to the SI constraint induced by the relay processing delay. In this paper, we first present a sufficient condition under which the relay amplification matrix has rank one structure. Then, for the case of rank one amplification matrix, the rate maximization problem is equivalently simplified into an unconstrained problem which can be locally solved using gradient ascent method. Next, we propose a penalty-based algorithmic framework, called P-BSUM, for a class of constrained optimization problems which have difficult equality constraints in addition to some convex constraints. By rewriting the rate maximization problem with a set of auxiliary variables, we apply the P-BSUM algorithm to the rate maximization problem in the general case. Finally, numerical results validate the efficiency of the proposed algorithms and show that the joint source-relay design approach under the rank one assumption could be strictly suboptimal as compared to the P-BSUM-based joint source-relay design approach.

Инвариант определяется по передаточной матрице пропорциональности между входной и выходной матрицами эффекта. Эффекты с одинаковым инвариантом образуют тренды развития пространственных, временных и вещественно-полевых ресурсов. Одним из примеров является известный тренд «точка-линия-поверхность-объем». По закону свертывания-развертывания тренды эффектов свернуты и развернуты в тренды инвариантов. Для трендов инвариантов предложены эквивалентные электрические аналоги, позволяющие численно сравнивать эффекты по степени сложности. Методику предполагается использовать для классификации эффектов по инвариантным свойствам, для синтеза физического принципа действия технических систем, а также в процессе изучения изобретательской физики в ТРИЗ.
Nonlinear evolution of electron shear flow instabilities in the presence of an external guide magnetic field

description: The dissipation mechanism by which the magnetic field reconnects in the presence of an external (guide) magnetic field in the direction of the main current is not well understood. In thin electron current sheets (ECS) (thickness ~ an electron inertial length) formed in collisionless magnetic reconnection, electron shear flow instabilities (ESFI) are potential candidates for providing an anomalous dissipation mechanism which can break the frozen-in condition of the magnetic field affecting the structure and rate of reconnection. We investigate the evolution of ESFI in guide field magnetic reconnection. The properties of the resulting plasma turbulence and their dependence on the strength of the guide field are studied. Utilizing 3-D electron-magnetohydrodynamic simulations of ECS we show that, unlike the case of ECS self-consistently embedded in anti-parallel magnetic fields, the evolution of thin ECS in the presence of a guide field (equal to the asymptotic value of the reconnecting magnetic field or larger) is dominated by high wave number non-tearing mode instabilities. The latter cause the development of, first, a wavy structure of the ECS. The turbulence, developed later, consists of current filaments and electron flow vortices. As a result of the nonlinear evolution of the instability, the ECS broadens simultaneously with its flattening in the central region mimicking a viscous-like turbulent dissipation. Later, the flattened ECS bifurcates. During the time of the bifurcation, the rate of the change of the mean electron flow velocity is proportional to the magnitude of the flow velocity, suggesting a resistive-like dissipation. The turbulence energy cascades to shorter wavelengths preferentially in the direction perpendicular to the guide magnetic field. The degree of anisotropy of the turbulence was found to increase with the increasing strength of the guide field.

Это различие обусловлено разностью классов и характера прорабатываемых проблем. Опыт внедрения ТРИЗ на предприятиях, в которых уже накоплен достаточно большой опыт внедрения Производственной системы показывает как преимущества, так и недостатки взаимодействия этих двух концепций в едином пространстве ресурсов и ограничений. Имеется множество видений того, как инструменты этих двух методологий должны или могут быть интегрированы. Их обзор представлен в публикациях многих авторов. В данной статье предлагается обновленный подход к такой интеграции, основанный на опыте существования двух методически направленных инфраструктур (ТРИЗ и Производственная система) на отечественных предприятиях.

description: Many real world networks have groups of similar nodes which are vulnerable to the same failure or adversary. Nodes can be colored in such a way that colors encode the shared vulnerabilities. Using multiple paths to avoid these vulnerabilities can greatly improve network robustness. Color-avoiding percolation provides a theoretical framework for analyzing this scenario, focusing on the maximal set of nodes which can be connected via multiple color-avoiding paths. In this paper we extend the basic theory of color-avoiding percolation that was published in [Krause et. al., Phys. Rev. X 6 (2016) 041022]. We explicitly account for the fact that the same particular link can be part of different paths avoiding different colors. This fact was previously accounted for with a heuristic approximation. We compare this approximation with a new, more exact theory and show that the new theory is substantially more accurate for many avoided colors. Further, we formulate our new theory with differentiated node functions, as senders/receivers or as transmitters. In both functions, nodes can be explicitly trusted or avoided. With only one avoided color we obtain standard percolation. With one by one avoiding additional colors, we can understand the critical behavior of color avoiding percolation. For heterogeneous color frequencies, we find that the colors with the largest frequencies control the critical threshold and exponent. Colors of small frequencies have only a minor influence on color avoiding connectivity, thus allowing for approximations.

description: Показано, что в середине ХХ века в научно-фантастической литературе стала набирать силу и к концу века утвердилась новая парадигма. В прежней научной фантастике, представителями которой были классики жанра Жюль Верн, Герберт Уэллс, Александр Беляев и др., в основу научно-фантастических идей ложились предположения о будущих технических изобретениях. Общим мнением авторов и читателей научной фантастики было: фантасты умеют (не все, конечно, но некоторые) предвидеть будущие изобретения. Такими были, например, изобретение подводной лодки с двойным корпусом (Ж. Верн, «20000 лье под водой», изобретение «лучей смерти» (Г. Уэллс, «Война миров»), постройка обитаемого искусственного спутника Земли (А. Беляев, «Звезда КЭЦ»). Однако к середине ХХ века начала формироваться новая парадигма: предвидение не изобретений, а открытий, и научно-фантастическое объяснение уже известных или еще пока не известных явлений природы. Парадигма эта оформилась окончательно в произведениях Г. Альтова (Альтшуллера) и В. Журавлевой. В предлагаемой статье я рассматриваю собственные научно-фантастические идеи в рамках описанной новой парадигмы и показываю соответствие этих идей парадигме научных открытий и объяснений в научной фантастике. Рассмотрены 74 научно-фантастические идеи из 35 рассказов, написанных ранее середины девяностых годов прошлого столетия. Проанализировано, с помощью каких приемов развития творческого воображения (РТВ) эти идеи были получены.

description: Context. Massive stars are generally believed to form in supersonic turbulent environment. However, recent observations have challenged this traditional view. High spatial and spectral resolution observations of the Orion Molecular Cloud and an infrared dark cloud G35.39 show a resolution-dependent turbulence, and that high-mass stars are forming exclusively in subsonic to transonic cores in those clouds. These studies demand a re-evaluation of the role of the turbulence in massive star formation. Aims. We aim to study the turbulence in a typical massive star-forming region G35.20-0.74 N with a sufficient spatial resolution to resolve the thermal Jeans length, and a spectral resolution to resolve the thermal linewidth. Methods. We use the ALMA dust continuum emission to resolve fragmentation, JVLA 1.2 cm continuum to trace ionized gas, and JVLA NH3 (1,1) to (7,7) inversion transition lines to trace linewidth, temperature, and dynamics. We fit those lines and remove line broadening due to channel width, thermal pressure, and velocity gradient to obtain a clean map of intrinsic turbulence. Results. We find that (1) the turbulence in G35.20 is overall supersonic, with mean and median Mach numbers 3.7 and 2.8, respectively. (2) Mach number decreases from 6-7 at 0.1 pc scale to <3 towards the central cores at 0.01 pc scale. (3) The central ALMA cores appear to be decoupled form the host filament, evident by an opposite velocity gradient and significantly reduced turbulence. Because of intense star formation activities in G35.20 (as compared to the relatively young and quiescent IRDC G35.39), the supersonic turbulence is likely replenished by protostellar outflows. G35.20 is, thus, representative of an evolved form of IRDC G35.39. More observations of a sample of IRDCs are highly demanded to further investigate the role of turbulence in initial conditions for the massive star formation.

description: Inertial modes have been observed on the Sun at low longitudinal wavenumbers. These modes probe the dynamics and structure of the solar convection zone down to the tachocline. While linear analysis allows the complex eigenfrequencies and eigenfunctions of these modes to be computed, it gives no information about their excitation nor about their amplitudes. We tested the hypothesis that solar inertial modes are stochastically excited by the turbulent motions entailed by convection. We have developed a theoretical formalism where the turbulent velocity fluctuations provide the mechanical work necessary to excite the modes. The modes are described by means of a 2D linear wave equation, relevant for the quasi-toroidal modes observed on the Sun, with a source term, under the beta plane approximation. Latitudinal differential rotation is included in the form of a parabolic profile that approximates the solar differential rotation at low and mid latitudes. We obtain synthetic power spectra for the wave's latitudinal velocity, longitudinal velocity, and radial vorticity, with azimuthal orders between 1 and 20. The synthetic power spectra contain the classical equatorial Rossby modes, as well as a rich spectrum of additional modes. The mode amplitudes are found to be of the same order of magnitude as observed on the Sun (~ 1 m/s). There is a qualitative transition between low and high azimuthal orders: the power spectra for m < 5 show modes that are clearly resolved in frequency space, while the power spectra for m > 5 display regions of excess power that consist of many overlapping modes. The general agreement between the predicted and observed inertial mode amplitudes supports the assumption of stochastic excitation by turbulent convection. Our work shows that the power spectra are not easily separable into individual modes, thus complicated the interpretation of the observations.

description: FORTESIE Deliverable 2.2 constitutes a cardinal step in the FORTESIE value chain. Building on deliverable D2.1 “End-user and pilot requirements and use cases description”, and following an SSH-oriented co-creation approach, D2.2 results feed: i) the FORTESIE technical activities (e.g., D2.3 “Reference architecture and components functionality M9”, D3.1 “Components’ functional design”); ii) the FORTESIE piloting activities (e.g., D4.1 “Pilots preparation, baseline analysis and planning”); and iii) the FORTESIE exploitation activities (e.g., D2.4 “Business models analysis for each service M9”). Towards effectively and efficiently realising the necessary work, a 5-steps methodology was developed and followed: Step 1. Collaborative Pilot Information Gathering; Step 2. Deriving Usage Scenarios; Step 3. Digital Components and Services Definition and Workflow; Step 4. Sessions with Pilot Teams – Validation and Fine-tuning; Step 5. FORTESIE Digital Components and Services. Following the aforementioned methodology, the specific needs/ expectations/ requirements of each pilot were reported and studied, 8 detailed end-to-end usage scenarios were derived and validated by the respective pilot teams. By reverse engineering the validated usage scenarios, the ecosystem of FORTESIE digital services, as well as their underlying components was designed. Specifically, 6 digital services were identified (namely “Data Sovereignty Service”, “Data Analysis Service”, “Behaviour & Recommendation Service”, “User Engagement Service”, “User Profile Service”, “Improvements Achieved Calculation and €G Rewarding Service”), plus the “One-Stop-Shop Marketplace Service” which includes 4 (sub-) services (namely “Renovation Recommendation Service”, “Info & Funding Service”, “Match-making Service”, “Knowledge Base”). More than 15 individual components have been prescribed. The last step towards completing the FORTESIE digital services’ ecosystem was the integration of individual digital services into pilot-specific service workflows; as not all pilots will use every FORTESIE digital service, it is only reasonable and meaningful to create service workflows that best fit each FORTESIE pilot’s needs. Thus, 7 pilot-specific service workflows were designed, communicated to, and validated by the FORTESIE pilot teams. It must be mentioned that task T2.2 “Value-added services design and specification based on SSH-approach (co-creation)” will deliver on M25 an updated version of the document at hand (i.e., deliverable D2.5 “FORTESIE services co-creation M25”), as it follows the dynamic and iterative approach of FORTESIE.
title: Suicides and ambient temperature in Switzerland: a nationwide time-series analysis

description: AIM OF THE STUDY: Previous literature suggests that ambient temperature may play a role in increasing the risk of suicide. Although in Switzerland suicides are an important cause of death, limited research exists on risk factors for suicidal behaviour, including ambient temperature. We aimed to assess the short-term association between ambient temperature and suicide risk in Switzerland between 1995 and 2016, and the differences by region, individual characteristics and method of suicide.
METHODS: We collected daily data on suicides and mean temperatures in each canton of Switzerland. We used a two-stage approach, consisting of a case time series analysis using conditional quasi-Poisson and distributed lag non-linear models followed by a multivariate meta-regression analysis. We conducted subgroup analyses by sex, age (<35, 35–65 and >65 years) and method of suicide (violent or nonviolent).
RESULTS: Between 1995 and 2016, there were a total of 24,067 suicides in Switzerland. Overall, we found a positive and non-linear temperature–suicide association in all regions. On average, the risk of suicide increased by 34% (1.34 relative risk [95% confidence interval: 1.19–1.52]) from the 10th to the 99th temperature percentile in Switzerland (lag period of 0–2 days). Indications of larger risks were mostly found in females, younger individuals (<35 years) and with nonviolent methods. Regional risks ranged from 24% (East region) to 55% (North-West region).
CONCLUSIONS: Our findings suggest that increasing temperatures could be considered a risk factor for suicidal behaviour in Switzerland. Knowledge of the profile of people committing suicide could help us to understand the mechanisms behind this association and thus support policymakers in suicide prevention.
Mutation enhances cooperation in direct reciprocity

description: Direct reciprocity is a powerful mechanism for evolution of cooperation based on repeated interactions between the same individuals. But high levels of cooperation evolve only if the benefit-to-cost ratio exceeds a certain threshold that depends on memory length. For the best-explored case of one-round memory, that threshold is two. Here we report that intermediate mutation rates lead to high levels of cooperation, even if the benefit-to-cost ratio is only marginally above one, and even if individuals only use a minimum of past information. This surprising observation is caused by two effects. First, mutation generates diversity which undermines the evolutionary stability of defectors. Second, mutation leads to diverse communities of cooperators that are more resilient than homogeneous ones. This finding is relevant because many real world opportunities for cooperation have small benefit-to-cost ratios, which are between one and two, and we describe how direct reciprocity can attain cooperation in such settings. Our result can be interpreted as showing that diversity, rather than uniformity, promotes evolution of cooperation.

description: Recently, the Delhi High Court delineates and circumscribes the scope of liability of Credit Ratings Agencies in the case of Jindal Power Limited v. ICRA Limited. The HC remarkably enumerated the grounds on which companies can challenge ratings issued by CRAs. The Court reasoned that CRAs provide expert opinions, with which the Court cannot interfere unless they are proved to be ‘perverse, arbitrary and mala fide’. Additionally, the case clarifies that CRAs are bound to observe the obligations as mentioned in the regulations and the same cannot be done away with by agreements concluded between the client and the CRA. This means that the court enumerates other grounds for suing a Credit Rating Agency before the court in India. Hence, the parameter for the court to interfere and entertain the disputes arising out of rating are based on those three grounds. Henceforth, the purpose of this Article analyzes the significance and potential implications of providing ‘perverse, arbitrary and mala fide’ as explicit grounds for challenging the ratings before the Court and its effects in India.
Hyperspherical cluster model for bosons: application to sub-threshold halo states in helium drops

description: To describe long-range behaviour of one particle removed from a few- or a many-body system, a hyperspherical cluster model has been developed. It has been applied to the ground and first excited states of helium drops with five, six, eight and ten atoms interacting via a two-body soft gaussian potential. Convergence of the hyperspherical cluster harmonics expansion is studied for binding energies, root-mean-squared radii and overlaps of the wave functions of two helium drops differing by one atom. It was shown that with increasing model space the functional form of such overlaps at large distances converges to the correct asymptotic behaviour. The asymptotic normalization coefficients that quantify the overlaps' amplitudes in this region are calculated. It was also shown that in the first excited state one helium atom stays far apart from the rest forming a two-body molecule, or a halo. The probability of finding the halo atom in the classically-forbidden region of space depends on the definition of the latter and on the number of atoms in the drop. The total norm of the overlap integrals, the spectroscopic factor, represents the number of partitions of a many-body state into a chosen state of the system with one particle removed. The spectroscopic factors have been calculated and their sum rules are discussed giving a further insight into the structure of helium drops.

description: For a subpopulation of energetic gamma-ray bursts (GRBs), a moderate baryonic loading may suffice to power ultra-high-energy cosmic rays (UHECRs). Motivated by this, we study the radiative signatures of cosmic-ray protons in the prompt phase of energetic GRBs. Our framework is the internal shock model with multicollision descriptions of the relativistic ejecta (with different emission regions along the jet), plus time-dependent calculations of photon and neutrino spectra. Our GRB prototypes are motivated by Fermi-Large Area Telescope-detected GRBs (including GRB 221009A) for which further, owing to the large energy flux, neutrino nonobservation of single events may pose a strong limit on the baryonic loading. We study the feedback of protons on electromagnetic spectra in synchrotron- and inverse Compton-dominated scenarios to identify the multiwavelength signatures, to constrain the maximally allowed baryonic loading, and to point out the differences between hadronic and inverse Compton signatures. We find that hadronic signatures appear as correlated flux increases in the optical-UV to soft X-ray and GeV–TeV gamma-ray ranges in the synchrotron scenarios, whereas they are difficult to identify in inverse Compton-dominated scenarios. We demonstrate that baryonic loadings around 10, which satisfy the UHECR energetic requirements, do not distort the predicted photon spectra in the Fermi Gamma-Ray Burst Monitor range and are consistent with constraints from neutrino data if the collision radii are large enough (i.e., the time variability is not too short). It therefore seems plausible that under the condition of large dissipation radii a population of energetic GRBs can be the origin of the UHECRs.
