In this paper, we explore a new problem of "temporal dense region query" to discover the dense regions in the constrainted time intervals which can be separated or not. A Querying tEmporal Dense Region framework (abbreviated as QED) proposed to deal with this problem consists of two phases: (1) an offline maintaining phase, to maintain the statistics of data by constructing a number of summariz...

At extreme pressures and temperatures, such as those inside planets and stars, common materials form new dense phases with compacted atomic arrangements and unusual physical properties. The synthesis and study of new phases of matter at pressures above 100 GPa and temperatures above 10(4) K--warm dense matter--may reveal the functional details of planet and star interiors, and may lead to mater...

The QCD axial anomaly, by coupling the chiral condensate and BCS pairing fields of quarks in dense matter, leads to a new critical point in the QCD phase diagram [1, 2], which at sufficiently low temperature should terminate the line of phase transitions between chirally broken hadronic matter and color superconducting quark matter. The critical point indicates that matter at low temperature sh...

We report on detections of the high-excitation CO J=6–5, J=4–3 lines in Mrk 231, a prototypical Ultra Luminous Infrared Galaxy (ULIRG) and Seyfert 1 QSO. These observations are combined with CO J=3–2, HCN J=4–3 (this work), and CO J=2–1, J=1–0, CO J=2–1, HCN J=1–0 measurements taken from the literature to provide better constraints on the properties of the molecular gas in an extreme starburst/...

This study focuses on the preparation and modification of a thin-film composite (TFC) hollow fiber polyamide membrane fabricated by the interfacial polymerization of Piperazine (PIP) and trimesoyl chloride (TMC) on a porous polysulfone substrate. The effects of triethylenetetramine (TETA) and silica nanoparticles (SiO2) contents in the aqueous phase (as the additives) on the morphology and perf...

The structural and dynamical properties of suspensions of self-propelled Brownian particles of spherical shape are investigated in three spatial dimensions. Our simulations reveal a phase separation into a dilute and a dense phase, above a certain density and strength of selfpropulsion. The packing fraction of the dense phase approaches random close packing at high activity, yet the system rema...

Abstract We investigated the chemical evolutions of gas-phase and grain-surface species across Taurus molecular cloud-1 (TMC-1) filament from translucent phase to dense phase. By comparing observations with modeling results an up-to-date network, we examined conversion processes for carbon-, oxygen-, nitrogen-, sulfur-bearing species, i.e., their initial atomic form main reservoir both in gas o...

The ground state of dense up and down quark matter under local and global charge neutrality conditions with β-equilibrium has at least four possibilities: normal, regular 2SC, gapless 2SC phases, and mixed phase composed of 2SC phase and normal components. The discussion is focused on the unusual properties of gapless 2SC phase at zero as well as at finite temperature.
