The Pauli Exclusion Principle (PEP) is one of the basic principles of modern physics and, even if there are no compelling reasons to doubt its validity, it is still debated today because an intuitive, elementary explanation is still missing, and because of its unique stand among the basic symmetries of physics. The present paper reports a new limit on the probability that PEP is violated by ele...
Salcedo Village has become more susceptible to urban heat effects because of its continuous development. This study investigates urban retrofit strategies that effectively mitigates the heat through modelling and simulation in ENVI-met. It is identified to have a maximum of 1-1.4K heat increase over 100% of its area, recorded during December 23:00 at 2m from the ground. The temperature increase...
We learn rich natural sound representations by capitalizing on large amounts of unlabeled sound data collected in the wild. We leverage the natural synchronization between vision and sound to learn an acoustic representation using two-million unlabeled videos. Unlabeled video has the advantage that it can be economically acquired at massive scales, yet contains useful signals about natural soun...
Several Herbrand proof procedures proposed during the 1960 decade are shown to be related in varying degrees. Most of the paper deals with a relationship between s-linear resolution and model elimination. Refinements of each are proposed and the spaces of ground deductions are shown to be isomorphic in a suitable sense. The two refined procedures are then studied at the general level where they...
The (v′ = 34, J′ = 14) level of the A∑u electronic state of Na2 has been selectively populated by excitation with the 578.1 nm line of a ring dye-laser with rhodamine 6G. Through collisions with (S1/2) Na atoms, energy is transferred to neighbouring rotational levels in Na2, and the density of these levels is determined by observing the fluorescence to the electronic ground state. From previous...
Thermokarst is the process of ground subsidence caused by either the thawing of ice-rich permafrost or the melting of massive ground ice. The consequences of permafrost degradation associated with thermokarst for surface ecology, landscape evolution, and hydrological processes have been of great scientific interest and social concern. Part of a tundra patch affected by wildfire in northern Alas...
The emitted radiation is usually in the visible region and at right angles to the incident radiation; only visible rarely when absorbed radiation is of visible high energy (short wavelength) in U.V region is the emitted radiation in U.V region. Molecules at room temperature are in ground electronic state. It absorbs energy and goes to excited electronic state. The groups of lines represent vibr...
A 915-MHz boundary layer wind profiler with radio acoustic sounding system (RASS) was sited 8 km from a very tall (450 m) television transmitting tower in north-central Wisconsin during the spring, summer, and autumn of 1995. The profiler measured wind means and variances, and the RASS attachment measured virtual temperature. These quantities are compared to measurements from cup and sonic anem...
The Pierre Auger Observatory is a detector for ultra-high energy cosmic rays. It consists of a surface array to measure secondary particles at ground level and a fluorescence detector to measure the development of air showers in the atmosphere above the array. The “hybrid” detection mode combines the information from the two subsystems. We describe the determination of the hybrid exposure for e...
We propose a set of “atomic cognitive operational representations” on which higher level cognitive representations and processes can be built, thus providing fundamental building blocks for cognitive mechanisms necessary for intelligent actions. The fundamental concepts involved are elemental temporal changes of some quantities and in this representational scheme the temporal dimension is expli...
