Constitutional monarchy offers Iran a politically stable and culturally resonant alternative to partisan republicanism. Grounded in both empirical research and philosophical tradition, it combines symbolic authority with institutional continuity, enabling national unity without authoritarianism. Monarchs function as neutral anchors above political conflict, often at lower public cost and with grea

We are interested in studying sets of the form U ( α ) := { x ∈ X : ∃ M = M ( x ) ⩾ 1 such that ∀ N ⩾ M , ∃ 1 ⩽ n ⩽ N such that d ( T n x , x ) ⩽ | λ | − α N } , where ( X , T , d ) is our metric dynamical system and | λ | > 1 . Although many results exist for the one dimensional case, not as many are known for systems in higher dimensions and especially in the hyperbolic case. We consider X = T 2

Mätning av relativ fuktighet, RF, i betong har tagit ett stort steg framåt med hjälp av trådlösa RF-prober som kan gjutas in direkt från start. I ett nyligen avslutat projekt vid avdelning Byggnadsmaterial vid Lunds tekniska högskola har ett mätsystem för RF i betong utvärderats. En av de största utmaningarna var att säkerställa att proberna klarar ingjutning och att de ger tillförlitliga mätninga

There is a strong societal demand for the development of effective and eco-friendly UV blocking substances for sunscreen applications. In this work, three AB2-type monomers with 0-2 methoxy groups are synthesized using three corresponding lignin-based monomeric aromatics and a potentially biobased hydandoin. The obtained AB2-type monomers are conveniently polymerized via conventional bulk polycond

Hardware distortion in large intelligent surfaces (LISs) may limit their performance when scaling up such systems. It is of great importance to model the non-ideal effects in their transceivers to study the hardware distortions that can affect their performance. Therefore, we have focused on modeling and studying the effects of nonlinear RX-chains in LISs. We first derive expressions for SNDR of a

Based on previous work, we extend a primal-dual semi-smooth Newton method for minimizing a general L^1-L^2-TV functional over the space of functions of bounded variations by adaptivity in a finite element setting. For automatically generating an adaptive grid, we introduce indicators based on a-posteriori error estimates. Further, we discuss data interpolation methods on unstructured grids in the

Losses and damages from climate change are not just a future risk but already a present reality, and “Loss and Damage” (L&D) as a policy domain has been formalised under the United Nations Framework Convention on Climate Change (UNFCCC), alongside mitigation and adaptation. While climate services currently provide strong support for adaptation and disaster recovery, here we propose that an exp

Many algorithms in computer graphics make use of acceleration structures such as Bounding Volume Hierarchies (BVHs) to speed up performance critical tasks, such as collision detection or ray-tracing. However, while the typical algorithms for constructing BVHs are relatively simple, actually implementing them for performance critical systems is still challenging. Further, to construct them as quick

In this work we find a unifying scheme for the known explicit complex-valued eigenfunctions on the classical compact Riemannian symmetric spaces. For this we employ the well-known Cartan embedding for those spaces. This also leads to the construction of new eigenfunctions on the quaternionic Grassmannians

The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is considered the primary instrument for assessing the presence and severity of obsessive-compulsive disorder (OCD). Conceptual and empirical critiques inspired the development of an updated version of the instrument, the Yale-Brown Obsessive Compulsive Scale-Second Edition (Y-BOCS-II), with a higher ceiling of OCD severity to better differentiate

The revised Payment Services Directive (PSD2) is reshaping traditional banking by requiring banks to grant licensed third-party providers (TPPs) access to customer data. This paper explores PSD2’s impact on Fintech market entry, assessing both opportunities and ongoing structural barriers. Through a qualitative investigation, it identifies key barriers such as API standardization gaps, data access

Time-frequency (TF) postprocessing methods are often used to form concentrated TF representations (TFRs) for nonstationary signals. Regrettably, most such techniques are sensitive to noise and tend to underestimate weak components when dealing with transient signals, resulting in sidelobes and low-resolution TFRs. In this work, we introduce a generalized group delay (GD) weighted sparse TF (GWSTF)

Biogas production from a mix of easily fermentable and fibrous energy crops was evaluated and compared for two different process types. The processes were a batch two-stage leach bed combined with an upflow anaerobic sludge blanket (UASB) process and a semi-continuous one-stage continuously stirred tank reactor (CSTR) process The specific methane yields after a processing time of 29-30 days were 2

Perceiving and understanding human motion is a fundamental problem in computer vision, with diverse applications encompassing sports analytics, healthcare monitoring, entertainment, and intelligent interactive systems. Multi-camera systems, by capturing multiple viewpoints simultaneously, enable robust tracking and reconstruction of human poses in 3D, overcoming limitations of single-view approach

Orbit separation dimension , previously introduced as amorphic complexity, is a powerful complexity measure for topological dynamical systems with pure-point spectrum. Here, we develop methods and tools for it that allow a systematic application to translation dynamical systems of tiling spaces that are generated by primitive inflation rules. These systems share many nice properties that permit th

The report presents an analysis of how sustainable business models can contribute to the transition to a more resource-efficient and circular economy. It highlights how economic, political, social and market factors influence the development and scaling of business models that reduce resource use, waste and climate impact. The results show that sustainable business models can be strengthened throu

The present invention relates to a method of removing an endotoxin from solution containing basic proteins. More specifically, the method of the present invention comprises the steps of adding the surfactant to solution containing the basic protein obtained from the recombinant microorganism and mixing the resultant, of loading the resultant solution on the cation exchange column, washing the cati
