Identity in Residential Architecture from the Viewpoint of Semiology (Qajar Period Houses and Contemporary Residential Complexes in Shiraz)

The deficiency of Iranian contemporary housing architecture has made this method of Architecture unable to meet the needs of Iranian families in recent years. Architecture is part of the identity of a society and has concepts and features derived from the community of its time. Therefore, in order to provide a correct solution for the modification of the Iranian contemporary housing architecture and to create its identity, it is necessary to recognize and analyze the signs existing in Iranian architecture throughout history. In this study, the architecture of the traditional Qajar era houses and contemporary residential complexes in Shiraz, with a semiotic approach, were analyzed in two layers of architecture and meta-architecture. The results of semiotics mechanism, questionnaires and interviews showed that the lack of attention to different layers of the signifieds and conformity of the signifier and the signified is the missing link of identity in the contemporary architecture of residential complexes. Also, it seems that the application of Qajar architectural signs to contemporary housing architecture can create identity in modern housing

Regeneration of Historical Fabrics with the Approach of Mental Image and Memory of the Places (Case study: Shiraz Historic Pathway “Khaneghah Ahmadi”)

The historic urban fabric has formed in a time process and todays it has been sorrunded by the current technologies and urban development. Although in their past these fabrics had been hierarchical and logical functions but today, in terms of structural and functional cases  it has deficiencies and can not meet the needs of their residents. One of the most important components of urban image maker that promotes a sense of place is historic urban spaces with physical and cultural values and the memories of a group in it and its rich background which leads to forming mental image and understanding map of the cities. On the other hand the mental image or the face of the city is all perceptions, knowledge, beliefs, conjectures and expectations that people have of their surroundings and creates the values, qualities, performances and different priorities in their minds, is a perfect tool for restoring the a historical fabric. Therefore restoring these  fabrics image maker elements in them such as valuable historic, cultural and religious elements can help to solve many problems resulted in lack of the sense of belonging to a place and finally lack of a place. In this study it was tried to use the potentials available in historic passage of Khanghah Ahmadi in Shiraz to make urban images through creating memorable mental images in line with promoting the sense of belonging to a place and strenghening the memories of a place and by rebuilding the passage and valuable historic, cultural and religious elements in it that each of them can be used as an image maker components, it can bring back the spirit of development and vivification. The main goal of this study is functional and the method used to collect the data was documentary and descriptive. Field studies and visual impressions in the study area were also conducted. The results were collected in the form of tables and by using SWOT techniques the sense of belonging to a place with promoting the mental image making in rebuilding the old fabrics were analyzed . the results indicated that the proposed solutions in line with refining or rebuilding the study area should be along with the least interferance and change and the most protection with emphasis on native endogenous and sustainable techniques based on mass participation. As a result strenghening the role of historic passage of Khanghah Ahmadi as a historic – cultural tourist attraction leads to increase in joining tourists and citizens and finally it leads to promoting and developing the sense of belonging to a place with urban memorable mental image

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

MUSiC : a model-unspecific search for new physics in proton-proton collisions at root s=13TeV

Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton collision data recorded at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), are presented. The MUSiC analysis searches for anomalies that could be signatures of physics beyond the standard model. The analysis is based on the comparison of observed data with the standard model prediction, as determined from simulation, in several hundred final states and multiple kinematic distributions. Events containing at least one electron or muon are classified based on their final state topology, and an automated search algorithm surveys the observed data for deviations from the prediction. The sensitivity of the search is validated using multiple methods. No significant deviations from the predictions have been observed. For a wide range of final state topologies, agreement is found between the data and the standard model simulation. This analysis complements dedicated search analyses by significantly expanding the range of final states covered using a model independent approach with the largest data set to date to probe phase space regions beyond the reach of previous general searches.Peer reviewe

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

Measurement of b jet shapes in proton-proton collisions at root s=5.02 TeV

We present the first study of charged-hadron production associated with jets originating from b quarks in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The data sample used in this study was collected with the CMS detector at the CERN LHC and corresponds to an integrated luminosity of 27.4 pb(-1). To characterize the jet substructure, the differential jet shapes, defined as the normalized transverse momentum distribution of charged hadrons as a function of angular distance from the jet axis, are measured for b jets. In addition to the jet shapes, the per-jet yields of charged particles associated with b jets are also quantified, again as a function of the angular distance with respect to the jet axis. Extracted jet shape and particle yield distributions for b jets are compared with results for inclusive jets, as well as with the predictions from the pythia and herwig++ event generators.Peer reviewe
