description: Ab initio calculations and a direct method have been applied to derive the phonon dispersion curves and phonon density of states for the TiC crystal. The results are compared and found to be in a good agreement with the experimental neutron scattering data. The force constants have been determined from the Hellmann-Feynman forces induced by atomic displacements in the 2x2x2 supercell. The calculated phonon density of states suggests that vibrations of Ti atoms form acoustic branches, whereas the motion of C atoms is confined to optic branches. The elastic constants have been found using the deformation method and compared with the results obtained from acoustic phonon slopes.

description: Lipopolyplexes, the multicomponent formulation, were successfully developed and delivered using modern physical force i.e., ultrasound and light. The obtained results were promising for improved in-vitro gene transfer in cancer cells. Both formulations exhibited encapsulation of the nucleic acid and displayed physicochemical characteristics ideal for cellular internalization via passive targeting. The ultrasound improves the transfection efficiency while remaining non-toxic to cancer cells. On other hand, photosensitizer loaded lipopolyplexes, promises an efficient gene transfer by photochemical internalization while also exhibiting photosensitizer induced cytotoxicity by photodynamic activity of photosensitizer. In summary, both gene delivery systems are excellent for effective in vitro gene transfer for tumor therapy.

description: Статья посвящена отдельным вопросам деятельности ростовщиков Новгородской губернии в конце ХIХ века. Главным образом, рассматривается полемика по поводу открытия ссудных касс под залог вещей, развернувшаяся между городскими властями и содержателями этих касс. Власти считали, что таким способом ростовщики стремятся легализовать свой промысел и всячески противились этому. Проблему обостряло отсутствие на тот момент действенной законодательной базы, позволявшей жестко контролировать ростовщичество. В статье затрагивается и проблема борьбы с ростовщичеством, например, попытки внедрения земством специальных складов для залога зерна, учреждение городских общественных ломбардов, кредитных товариществ и потребительских обществ.

description: The purpose of this technical document is to assess the effect of a gain reduction on low- and high-level analysis results and to investigate the option of using a common lowered gain for both, dark and moonlight observations. Using a sequence of six Crab Nebula runs taken at alternating gain settings, it was shown that decreasing the gain factor from 80 to 60 Analog-to-digital counts per photo-electron (ADC/pe) has no significant effect on the telescope system sensitivity under dark-sky conditions. This result confirms expectations that such a change in gain has a comparatively small effect on the signal readout. In particular, the following results were obtained: 1. The trigger rates and event statistics are comparable for both gains. 2. The distributions of Hillas parameters are consistent for both gains. 3. The spectral analysis results are consistent within about 10%. The efficiency of detecting gamma rays is energy-independent and consistent for both gains, indicating no loss of performance at any energy.

description: Die chronisch entzündlichen Immundermatosen (Psoriasis mit und ohne Arthritis, Atopische Dermatitis, Urtikaria) stellen einen wichtigen und prozentual großen Anteil an den Krankheitsbildern in einer dermatologischen Praxis dar. Zur Optimierung der Versorgung der Patienten mit immun-dermatologischen Erkrankungen führen wir seit 2019 eine Spezialimmunsprechstunde durch. Hier stellen sich Patienten mit den oben genannten Erkrankungen, aber auch mit Akne inversa, bullösen Dermatosen, mit Hauterscheinungen im Rahmen oder wegen Nebenwirkungen von Therapien bei Autoimmunkrankheiten anderer Organsysteme (zum Beispiel Myasthenia Gravis, SLE, Morbus Sjögren, Multiple Sklerose), mit Immunmangelerkrankungen oder Hyposensibilisierung-Initiierung vor. Immunmodulierende Therapien mit Biologika (monoklonale Antikörper) sowie mit klein-molekularen Arzneimitteln, wie zum Beispiel JAK-Inhibitoren, zeigen ein günstiges Wirkungs-Sicherheits-Verhältnis und werden in unserer Praxis als therapeutisches Prinzip breit eingesetzt. Neben der immunologischen Diagnostik und den Immuntherapien gehört auch der Einsatz von relevanten Impfstoffen zum Gebiet der Immundermatologie. Gerade im Zusammenhang mit der SARS-CoV-2-Infektion und der Covid-19 Erkrankung ergaben sich bei unseren Patienten zahlreiche, häufig immunologische Fragen. Das Management der Therapie entzündlicher Immundermatosen mit immunmodulierenden Biologika ist komplex und umfasst die saubere Indikationsstellung, das Befolgen eines Therapiealgorithmus, das Erkennen und Diagnostizieren von potenziellen Nebenwirkungen sowie die Foto- und schriftliche Dokumentation. Dies in den Alltag einer dermatologischen Praxis organisatorisch und vor allem auch wirtschaftlich einzubetten stellt eine große Herausforderung dar. Die Zusammenarbeit der Praxis mit der Klinik ist, besonders auf dem Gebiet der Immuntherapie und in Zeiten der Corona-Pandemie, von essenzieller Bedeutung. Ein Teil unserer Patienten wurde aus Studien rekrutiert, die an Kliniken durchgeführt wurden. Durch die immunmodulierende Behandlung von mehr als 200 Patienten unter Praxisbedingungen innerhalb von zwei Jahren, haben wir reichlich Erfahrungen gesammelt. Diese werden in dieser Arbeit zusammengefasst unter Nutzung von 8 eigenen Publikationen (2 Erstautorin, 6 Mitautorin). Die klinischen Daten wurden retrospektiv analysiert. Es werden Therapieverläufe vorgestellt und Schlussfolgerungen gezogen. Mit der vorgelegten Arbeit soll ein Beitrag geleistet werden zur Anwendung von modernen Immuntherapien in der dermatologischen Praxis.

description: In the past years quasi-conformal mapping has been typically used to design broadband electromagnetic cloaks. However, this technique has some inherit practical limitations such as the lateral beam shift, rendering the device visible or difficult to hide a large object. In this work we circumvent these issues by using strict conformal mapping to build the first isotropic cloak. Microwave near-field measurement shows that our device (with dielectric constant larger than unity everywhere) has a very good cloaking performance and a broad frequency response. The present dielectric approach could be technically extended to the fabrication of other conformal devices at higher frequencies.

description: Ransomware, a type of malware that prevents targets from accessing their own data unless a ransom is paid, has become an irresistibly lucrative tool for cyber criminals. In recent years, high-profile ransomware attacks have successfully demanded hefty ransoms from organizations worldwide, with some attacks even targeting nationally critical infrastructure. Ransomware is highly effective for extracting money, but could this technology be used by other actors, such as states, to demand things other than money? This thesis seeks to answer whether and how ransomware can be used between states to directly coerce behavioral change. To answer this question, this thesis first presents a game-theoretical model of ransomware that offers a means of logically theorizing how ransomware against states might play out. The thesis then turns to case studies of two notable criminal ransomware incidents, examining them through the lens of theories of interstate coercion. This study finds that ransomware offers some upsides as a coercive weapon between states, including the ability to improve the attack's credibility. However, ransomware is still limited by the need to assure the target that compliance will allow them to recover their data. Although it is difficult to conclusively predict the future of ransomware based on available evidence, these limitations suggest that ransomware will be bounded to narrow use cases. Nonetheless, by examining this hypothetical cyber tactic, this thesis offers some precautionary insights and reinforces the importance of strengthening the cybersecurity of critical infrastructure.

description: Here I am proposing a translation and discussion of the De Colore, one of the short scientific treatises written by Robert Grosseteste. In this very short treatise of the mid-1220s, Grosseteste continued the discussion on light and colours he started in the De Iride. He describes two manners of counting colours: one gives an infinity of tones, the other counts seven colours. In both cases, colours are created by the purity or impurity of the transparent medium when light is passing through it. This medieval framework survived until Newton's experiments with prisms.

description: The scattering of electromagnetic waves by an obstacle is analyzed through a set of partial differential equations combining the Maxwell's model with the mechanics of fluids. Solitary type EM waves, having compact support, may easily be modeled in this context since they turn out to be explicit solutions. From the numerical viewpoint, the interaction of these waves with a material body is examined. Computations are carried out via a parallel high-order finite-differences code. Due to the presence of a gradient of pressure in the model equations, waves hitting the obstacle may impart acceleration to it. Some explicative 2D dynamical configurations are then studied, enabling the study of photon-particle iterations through classical arguments.

description: Pancreatic cancer is one of the deadliest cancer types and is characterized by a highly immunosuppressive tumor microenvironment. The abundance of T cells in the tumor microenvironment has been shown to improve the prognosis for pancreatic cancer patients. Nevertheless, T cell exhaustion can cause a lack T cell effector function and therefore contribute to cancer immune evasion. Cytokines, like the NLRP3-dependent cytokines IL-18 and IL-1β, are highly involved in the regulation of the function and exhaustion of T cells. Additionally, elevated levels of IL-18 and IL-1β have been found in various cancer types, inter alia pancreatic cancer. Therefore, this study aimed to characterize the role of IL-18 and IL-1β in T cell exhaustion and dysfunction in a pancreatic cancer model. It is highly important to understand the function and plasticity of T cells in pancreatic cancer in order to find new therapy approaches. Therefore, the goal of this study was to determine i) the effect of IL-18 on T cell exhaustion in vitro, ii) the molecular mechanisms of IL-18-mediated exhaustion of CTLs, iii) the effects of IL-1β and IL-18 on Th1 and Treg differentiation in vitro, iv) the effect of IL-1R and IL-18R signaling in adoptively transferred CD4+ T cells on endogenous T cell populations in a murine pancreatic cancer model and v) the effect of IL-1R and IL-18R signaling in adoptively transferred CD4+ T cells on tumor rejection and on the function of adoptively transferred tumor specific CTLs in a murine pancreatic cancer model. During this study, an in vitro exhaustion model was used which showed that IL-18 induces a more severe exhausted phenotype of antigen-specific CD8+ T cells in vitro. Additionally, it was used to determine that the IL-2/STAT5/Akt/mTOR pathway plays a key role in the IL-18 mediated induction of exhaustion. Therefore, this study identified IL-18 and the IL-2/STAT5/Akt/mTOR pathway as potential targets for immunotherapy in cancer. This study also revealed a Th1 inducing and iTreg inhibiting function of IL-18 receptor signaling in vitro and therefore provides valuable information on IL-18 receptor signaling in CD4+ T cell subsets that are important for future in vitro and in vivo studies. IL-18R and IL-1R signaling in adoptively transferred CD4+ T cells in a murine pancreatic cancer model neither had an impact on endogenous CD4+ or CD8+ T cells nor did they influence tumor growth or tumor rejection by antigen-specific CTLs. Nevertheless, the mice strains generated during this study are a helpful tool for future studies focusing on the role of IL-18 and IL-1 receptor signaling in antigen-specific CD4+ T cells and Tregs.

This paper extols and illustrates the virtues of the ellipse and her higher-dimensional cousins for both these purposes in a variety of contexts, including linear models, multivariate linear models and mixed-effect models. We emphasize the strong relationships among statistical methods, matrix-algebraic solutions and geometry that can often be easily understood in terms of ellipses.

The Community Impact of Post-Earthquake Safety Decisions Based on Damage to Tall Buildings and Elevated Hazard Due to Aftershocks

description: A key component of community resilience is the ability to recover community functions after an earthquake. Resilience planning focuses on identifying critical functions, setting recovery time targets for various hazard levels, and assessing the gap between the desired and the anticipated performance. These performance assessments should consider all potential disruptions to community functions, such as damage that makes buildings unsafe, damage to equipment and architectural ﬁnishes that makes buildings non-functional, and loss of utility services or transportation access. A recovery-based assessment includes both the initial loss of functionality and the process for restoring it, including stabilizing unsafe buildings and securing the necessary resources to initiate building repairs. A heavily damaged building has an elevated risk of collapse during an aftershock, endangering the occupants in nearby buildings. Post-earthquake safety inspectors evaluate which damaged buildings to red tag and where to set up safety cordons, restricting access to potential fall zones. This dissertation focuses on these access restrictions associated with unsafe buildings.
Post-earthquake decisions regarding which buildings are safe to re-enter are an important part of a community’s recovery process. Unsafe buildings and neighborhoods should be marked as such, alleviating the public’s uncertainty as they take stock of their surroundings. However, these decisions should be made carefully, recognizing their impact on the community. Displacing too many residents through overly conservative red tagging would increase the potential for permanent outmitgration. Businesses in an inaccessible downtown may fail or need to relocate–to the outlying areas or to another city. Therefore, while safety cordons are imperative, their presence should be minimized where feasible, either by building retroﬁts to proactively reduce the likelihood of earthquake damage or by facilitating building inspection and stabilization eﬀorts to remove the cordons as soon as possible. This dissertation proposes tools for quantifying three aspects of access restrictions: the additional community downtime due to safety cordons, the reduced safety of a damaged building, and the elevated risk of building collapse in the presence of aftershocks.
Ballots & Bullets: Understanding the Conditions that Facilitated Hybrid Actor Participation in Elections in Iraq and Lebanon

description: Hezbollah’s transition to parliamentary politics spurned the term “Hezbollah model,” but it is far from the only hybrid actor to hold seats in a national government. What are the conditions that facilitate hybrid actor participation in national elections? This thesis takes a qualitative approach to understand the interplay of these conditions for Hezbollah in Lebanon and the Sadrist movement in Iraq. The thesis makes a probabilistic argument about the presence and significance of four conditions: government tolerance, a supportive constituency, power vacuum, and foreign involvement. 

Hybrid actor electoral participation has important implications for policymakers who are interested in preventing these actors from integrating with state governments, and in slowing the spread of Iranian influence in the Middle East, as Iran has had the most success in cultivating mutually beneficial relationships with hybrid actors in the region. Specifically, understanding the conditions that precipitate participation in elections opens the door to preventive measures in other countries in which hybrid actors flourish but have yet to enter into politics.

description: Ground-plane cloaks, which transform a curved mirror into a flat one, and recently reported at wavelengths ranging from the optical to the visible spectrum, bring the realm of optical illusion a step closer to reality. However, all carpet-cloaking experiments have thus far been carried out in the far-field. Here, we demonstrate numerically and experimentally that a dielectric photonic crystal (PC) of a complex shape made of a honeycomb array of air holes can scatter waves in the near field like a PC with a at boundary at stop band frequencies. This mirage effect relies upon a specific arrangement of dielectric pillars placed at the nodes of a quasi-conformal grid dressing the PC. Our carpet is shown to work throughout the range of wavelengths 1500nm to 1650nm within the stop band extending from 1280 to 1940 nm. The device has been fabricated using a single- mask advanced nanoelectronics technique on III-V semiconductors and the near field measurements have been carried out in order to image the wave fronts's curvatures around the telecommunication wavelength 1550 nm.

Assessing Red Lines in the US-China-Taiwan Trilateral Relationship

description: The idea of “red lines” has become a favorite catch-all term to discuss coercion, grey area tactics, and escalation. Particularly in the case of the US-China relationship over Taiwan, policymakers and scholars use red lines as a shorthand to conceptualize crisis thresholds, a point where ambiguity ends, and the stakes are highest. But there is limited consensus on the definition of red lines, and even less consensus on where red lines are between the US and China. This thesis creates a theoretical framework for understanding red lines and applies to it to the US-China-Taiwan case to explore how the US and China treat red lines in practice, and why some red lines fail where others succeed. Drawing on a set of case studies of Taiwan-centered red lines, I analyze how their integrity has evolved, contextualizing violations and enforcement through a typology. I assess red lines based on four main components: a situational threshold, demand, threat, and justification, and suggest that the strength of a red line is highly dependent on having all four components. Particularly in an era of grey area conflict between the US and China, understanding how to draw red lines most effectively, and which red lines are de jure versus de facto, is essential for preventing miscommunication and unwanted escalation.

description: This presentation reviews an approach to nuclear many-body systems based on the spontaneously broken chiral symmetry of low-energy QCD. In the low-energy limit, for energies and momenta small compared to a characteristic symmetry breaking scale of order 1 GeV, QCD is realized as an effective field theory of Goldstone bosons (pions) coupled to heavy fermionic sources (nucleons). Nuclear forces at long and intermediate distance scales result from a systematic hierarchy of one- and two-pion exchange processes in combination with Pauli blocking effects in the nuclear medium. Short distance dynamics, not resolved at the wavelengths corresponding to typical nuclear Fermi momenta, are introduced as contact interactions between nucleons. Apart from a set of low-energy constants associated with these contact terms, the parameters of this theory are entirely determined by pion properties and low-energy pion-nucleon scattering observables. This framework (in-medium chiral perturbation theory) can provide a realistic description of both isospin-symmetric nuclear matter and neutron matter. The importance of three-body forces is emphasized, and the role of explicit Delta(1232)-isobar degrees of freedom is investigated in detail. Nuclear chiral thermodynamics is developed and a calculation of the nuclear phase diagram is performed. This includes a successful description of the first-order phase transition from a nuclear Fermi liquid to an interacting Fermi gas and the coexistence of these phases below a critical temperature T_c. Density functional methods for finite nuclei based on this approach are also discussed. Effective interactions, their density dependence and connections to Landau Fermi liquid theory are outlined. Finally, the density and temperature dependence of the chiral (quark) condensate is investigated.

description: The interaction radius of a resonance is an important physical quantity to describe the structure of a resonance. But, for a long time, physicists do not find a reliable way to measure the magnitude of the interaction radius of a resonance. In this paper, a method is proposed to measure the interaction radius in physics analysis. It is found that the centrifugal barrier effects have great influence to physical results obtained in the PWA fit, and the interaction radius of some resonances can be well measured in the fit.

description: This research is the preliminary flow system design of a hybrid rocket apogee kick motor using liquid nitrous oxide as oxidizer and solid high-density polyethylene as fuel. Empirical formulations of fuel regression rate and nozzle thermochemical erosion are formed based on static firing test data and included in the design process. Results show that structural and propellant mass is minimized in the cases with no nozzle erosion and a regression rate exponent of 0.5

description: A mobile ad hoc network (MANET) is a collection of autonomous nodes that communicate with each other by forming a multi-hop radio network and maintaining connections in a decentralized manner. Security remains a major challenge for these networks due to their features of open medium, dynamically changing topologies, reliance on cooperative algorithms, absence of centralized monitoring points, and lack of clear lines of defense. Protecting the network layer of a MANET from malicious attacks is an important and challenging security issue, since most of the routing protocols for MANETs are vulnerable to various types of attacks. Ad hoc on-demand distance vector routing (AODV) is a very popular routing algorithm. However, it is vulnerable to the well-known black hole attack, where a malicious node falsely advertises good paths to a destination node during the route discovery process but drops all packets in the data forwarding phase. This attack becomes more severe when a group of malicious nodes cooperate each other. The proposed mechanism does not apply any cryptographic primitives on the routing messages. Instead, it protects the network by detecting and reacting to malicious activities of the nodes. Simulation results show that the scheme has a significantly high detection rate with moderate network traffic overhead and computation overhead in the nodes.

description: Resumen:
Veinticinco años después de que se firmaran los Acuerdos de Paz que terminaron con 36 años
de conflicto armado en Guatemala, no se ha llevado a cabo la implementación del Acuerdo de
Identidad y Derechos de los Pueblos Indígenas. Los poderes que controlaban el Estado que
ejecutó el genocidio del Pueblo Maya-Ixil, entre otros crimenes de lesa humanidad, aún
controlan las tres ramas del gobierno. Incluyendo el Ministerio de Educación, dentro de la rama
ejecutiva. Cuando las instituciones educativas son entendidas como espacios que reproducen
las estructuras coloniales capitalistas, se hace necesario (re)imaginar la educación. Semillas de
Atitlán localizado en Sololá y, el Proyecto Luis de Lión en Sacatepéquez, han traído a la
práctica el desafío de (re)imaginar la educación. Estos proyectos liderados por mujeres Mayas
y Mestizas son un nuevo estándar de lo que puede ser la educación y nos muestran que las
relaciones con los estudiantes, las familias y la comunidad pueden ser transformadas cuando la
enseñanza y el aprendizaje se hacen desde las perspectivas comunitarias. A través de esta tesis,
voy a yuxtaponer las condiciones dentro de las cuales el Estado provee la educación y los
proyectos transformadores que Anita Waxqi y Mayarí de León están liderando en sus
comunidades, el impacto que tiene en los estudiantes y las dificultades a las que se enfrentan
al desafiar el poder normativo del Estado.
Abstract:
Twenty-five years after the Peace Accords that ended the 36-year armed conflict in Guatemala,
there has not been an adequate implementation of the Agreement on Identity and Rights of
Indigenous Peoples. The powers that controlled the state during the genocide of the pueblo
Maya-Ixil, amongst other crimes against humanity, still holds power over the three branches of
government. This includes the Ministry of Education in the executive branch. When formal
education institutions are understood as sites that reproduce capitalist and settler-colonial
structures, another way of (re)imagining education is needed. Semillas de Atitlán located in
Sololá, and the Proyecto Luis de Lión in Sacatepéquez, have brought to praxis the challenge of
(re)imagining education. These projects led by Mayan and Mestiza women are setting a new
standard of what education can be. They are also demonstrating that the relationships amongst
students, families and the community at large can be transformed when teaching and learning
are carried out through a community perspective. Through this thesis, I will juxtapose the
conditions under which the state provides education and the transformative projects that Mayarí
de León and Anita Waxqi, respectively, are leading in their communities, the impact that it has
on the children, and the struggles they face by defying the normative rule of the state.

description: Carbon-based caged and heterocyclic compounds tend to have strained molecular structures leading to high heats of formation and energetic behavior. In the current paper, molecular modelling calculations for 10 caged compounds of this type along with 2 strained aliphatic compounds and 4 simple cyclic chains are presented in view of their possible use as oxidizers in propulsion applications. Density functional theory (B3LYP) was employed for the geometry optimization of the proposed molecular structure using the 6-311++G(d,p) basis set. Heats of formation of the compounds were calculated using the molecular modeling results and their specific impulses were computed using the NASA CEA software package to evaluate their potentials as propellant oxidizers

description: Mechanosensitive ion channels have long been investigated in the field of neurobiology. However, their roles in other tissues, especially in epithelial tissues, remained elusive. Epithelial cells, being closely packed in tissues, can sense and are able to respond to the mechanical forces generated and transmitted by their neighbours. Such mechanical communication among epithelial cells is classically achieved via the cadherin-catenin complexes at the cell junctions. The mechanical signals received by the mechanomolecules are thereafter either directly transmitted through the cytoskeletal reorganisation or are transduced into biochemical signals inside the cells. We hypothesised that mechanosensitive ion channels can also act as mechanomolecules in epithelial cells. Based on the previous findings, I went on to investigate if NompC, the first to be known mechanosensitive channel in Drosophila, is expressed in the epithelial cells too and, if so, what purpose it serves there. I have found a widespread expression of the NompC channel in multiple tissues, including the amnioserosa, a highly dynamic and short-lived epithelial tissue during dorsal closure, a major morphogenetic transformation event in Drosophila. The absence of NompC led to multiple defects in the dorsal closure process. Amnioserosa cells exhibit a high degree of coordination, manifested through a synchronised oscillatory behaviour between neighbouring cells. My study revealed that NompC is a critical regulator of this synchrony. I also found that NompC is responsive to mechanical forces in the amnioserosa tissue and drives Ca2+ influx into the cells. Depletion of NompC caused a disruption in directional force distribution across the tissue and an anisotropic cellular morphology. I found NompC is important to facilitate active cell oscillation. An absence of NompC disables the cells to relay external mechanical inputs across the tissue efficiently. I found several interesting cytoskeletal changes that directly or indirectly are supposed to be affected by NompC as the molecular basis that translates into the downstream tissue-scale behaviour. In brief, this study provides us with a clear understanding of the roles of a mechanosensitive ion channel, NompC, in epithelial cells. However, more research is needed to elucidate the gating activity and the interacting partners of the NompC channel.

description: Lottia. gigantea is a keystone species in the rocky intertidal zone (Paine, 1994). Better understanding of L.gigantea will provide further insight to the community ecology of the rocky intertidal zone. While in the field at Cabrillo Point, I observed facilitative interactions between L.gigantea, L.scabra, and microalgae. Two field sites were created to investigate temperature differences between limpets with microalgae on their shell and those without. Limpets were studied for three days. At site and on each day, limpets with microalgae were .383 degrees Celsius warmer than limpets without microalgae. In addition, I discovered a significant main effect of site on the difference in temperature between limpet with algae and limpets without (p-value = .00451). My finding provokes further investigation of the interesting relationship between microalgae and limpet shell temperature.
Canalization and control in automata networks: body segmentation in Drosophila melanogaster

description: We present schema redescription as a methodology to characterize canalization in automata networks used to model biochemical regulation and signalling. In our formulation, canalization becomes synonymous with redundancy present in the logic of automata. This results in straightforward measures to quantify canalization in an automaton (micro-level), which is in turn integrated into a highly scalable framework to characterize the collective dynamics of large-scale automata networks (macro-level). This way, our approach provides a method to link micro- to macro-level dynamics -- a crux of complexity. Several new results ensue from this methodology: uncovering of dynamical modularity (modules in the dynamics rather than in the structure of networks), identification of minimal conditions and critical nodes to control the convergence to attractors, simulation of dynamical behaviour from incomplete information about initial conditions, and measures of macro-level canalization and robustness to perturbations. We exemplify our methodology with a well-known model of the intra- and inter cellular genetic regulation of body segmentation in Drosophila melanogaster. We use this model to show that our analysis does not contradict any previous findings. But we also obtain new knowledge about its behaviour: a better understanding of the size of its wild-type attractor basin (larger than previously thought), the identification of novel minimal conditions and critical nodes that control wild-type behaviour, and the resilience of these to stochastic interventions. Our methodology is applicable to any complex network that can be modelled using automata, but we focus on biochemical regulation and signalling, towards a better understanding of the (decentralized) control that orchestrates cellular activity -- with the ultimate goal of explaining how do cells and tissues 'compute'.
