This study describes the successful upgrade of a mechanically pumped CO$_2$ two-phase cooling system in space by designing a new pump module for the Alpha Magnetic Spectrometer-02 on the International Space Station. Key factors for mission success are emphasized, including achieving high coolant filling accuracy within 10% of the target and maintaining system stability within ±1 C. [...]

First Result from the Alpha Magnetic Spectrometer on the International Space Station: Precision Measurement of the Positron Fraction in Primary Cosmic Rays of 0.5–350 GeV / AMS Collaboration
A precision measurement by the Alpha Magnetic Spectrometer on the International Space Station of the positron fraction in primary cosmic rays in the energy range from 0.5 to 350 GeV based on 6.8×106 positron and electron events is presented. The very accurate data show that the positron fraction is steadily increasing from 10 to ∼250 GeV, but, from 20 to 250 GeV, the slope decreases by an order of magnitude. [...]

The Alpha Magnetic Spectrometer (AMS) on the International Space Station. I: Results from the test flight on the space shuttle / AMS Collaboration
The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttle Discovery during flight STS-91 (June 1998) in a 51.7° orbit at altitudes between 320 and 390 km . A search for antihelium nuclei in the rigidity range 1– 140 GV was performed. [...]

A New Boson with a Mass of 125 GeV Observed with the CMS Experiment at the Large Hadron Collider / CMS Collaboration
The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would verify the existence of a complex scalar field thought to give mass to three of the carriers of the electroweak force—the W+, W–, and Z0 bosons—as well as to the fundamental quarks and leptons. [...]

Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC / CMS Collaboration
Results are presented from searches for the standard model Higgs boson in proton-proton collisions at $\sqrt{s}$=7 and 8 TeV in the CMS experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at 7 TeV and 5.3 inverse femtobarns at 8 TeV. The search is performed in five decay modes: $\gamma\gamma$, ZZ, WW, $\tau^+ \tau^-$, and $b\bar{b}$. [...]

Isotopic Composition of Light Nuclei in Cosmic Rays: Results from AMS-01 / AMS-01 Collaboration
The variety of isotopes in cosmic rays allows us to study different aspects of the processes that cosmic rays undergo between the time they are produced and the time of their arrival in the heliosphere. In this paper, we present measurements of the isotopic ratios $^2$H/$^4$He, $^3$He/$^4$He, $^6$Li/$7$Li, $7$Be/($^9$Be+$^{10}$Be), and $^{10}$B/$^{11}$B in the range 0.2-1.4 GeV of kinetic energy per nucleon.

Relative Composition and Energy Spectra of Light Nuclei in Cosmic Rays. Results from AMS-01 / AMS-01 Collaboration
Measurement of the chemical and isotopic composition of cosmic rays is essential for the precise understanding of their propagation in the galaxy. While the model parameters are mainly determined using the B/C ratio, the study of extended sets of ratios can provide stronger constraints on the propagation models. [...]

Integration of the End Cap TEC+ of the CMS Silicon Strip Tracker / Tracker End Cap Collaboration
The silicon strip tracker of the CMS experiment has been completed and inserted into the CMS detector in late 2007. The largest sub-system of the tracker is its end cap system, comprising two large end caps (TEC) each containing 3200 silicon strip modules. [...]

Petal Integration for the CMS Tracker End Caps / Bergauer, Thomas ; Dragicevic, Marko ; Friedl, Markus ; Hansel, S ; Hrubec, Josef ; Krammer, Manfred ; Pernicka, Manfred ; Beaumont, Willem ; De Wolf, Eddi A ; Bouhali, Othmane et al.
This note describes the assembly and testing of the 292 petals built for the CMS Tracker End Caps from the beginning of 2005 until the summer of 2006. Due to the large number of petals to be assembled and the need to reach a throughput of 10 to 15 petals per week, a distributed integration approach was chosen. [...]
