This thesis reports the latest measurements on one of the leading dark matter searches conducted by the Compact Muon Solenoid (CMS) experiment at CERN, leading to some of the most stringent constraints on hypothesized interactions between the Higgs boson and dark matter. The thesis also includes further research about the future outlook of the experiment, including exploratory research on the adaptation of deep learning models in future dark matter analyses to improve analysis sensitivity, and the design of a new type of data processing hardware to be used in the next phase of the CMS experiment.

?Hörmander's operators are an important class of linear elliptic-parabolic degenerate partial differential operators with smooth coefficients, which have been intensively studied since the late 1960s and are still an active field of research. This text provides the reader with a general overview of the field, with its motivations and problems, some of its fundamental results, and some recent lines of development.

The Open Mapping and Closed Graph Theorems in Topological Vector Spaces

The Open Mapping and Closed Graph Theorems in Topological Vector Spaces

THE main purpose of writing this monograph is to give a picture of the progress made in recent years in understanding three of the deepest results of Functional Analysis-namely, the open-mapping and closed­ graph theorems, and the so-called Krein-~mulian theorem. In order to facilitate the reading of this book, some of the important notions and well-known results about topological and vector spaces have been collected in Chapter 1. The proofs of these results are omitted for the reason that they are easily available in any standard book on topology and vector spaces e.g. Bourbaki [2], Keiley [18], or Köthe [22]. The results of Chapter 2 are supposed to be weil known for a study of topological vector spaces as weil. Most of the definitions and notations of Chapter 2 are taken from Bourbaki's books [3] and [4] with some trimming and pruning here and there. Keeping the purpose of this book in mind, the presentation of the material is effected to give a quick resume of the results and the ideas very commonly used in this field, sacrificing the generality of some theorems for which one may consult other books, e.g. [3], [4], and [22]. From Chapter 3 onward, a detailed study of the open-mapping and closed-graph theorems as weil as the Krein-~mulian theorem has been carried out. For the arrangement of the contents of Chapters 3 to 7, see the Historical Notes (Chapter 8).

Seminal studies on the network traffic, revealed the certain statistical property (self-similar nature) of network traffic, and how they degrades the network performance. Markovian models are well recognized as the appropriate self-similar traffic models. Markovian arrival process (MAP) has been proposed to emulate self similarity over the desired time-scales. Markov modulated Poisson process (MMPP) a particular case of MMPP emulating self-similar traffc over different time scale is fitted by several authors using second order statistics. The two state Circulant Markov modulated Poisson process which is restricted version of two state MMPP. The CMMPP emulating self-similar traffic is fitted by equating the variance. The mean waiting time and packet loss behavior are calculated by using the models of CMMPP/M/1 CMMPP/M/1/K queuing systems wherein service time is taken to be deterministic exponential distributions. It is clear from the numerical results the time scale do have collision on delay packet loss probability. Loss probability of packets increases if H and Traffic intensity is increase. This type of analysis is useful in dimensioning the router.

La abeja occidental (Apis mellifera) es un insecto 'eusociale', que pertenece a la familia de las Hymen pteras. Las poblaciones se diferencian en reinas que producen cr as y trabajadores no reproductivos, los cuales recogen y procesan los alimentos y producen la apitoxina. El veneno de abeja est compuesto por varios p ptidos, uno de los cuales es la melitina, siendo este una prote na que posee un efecto bactericida y ayuda a mejorar el sistema inmunol gico.
