1 Proper contexts Frege (1918-1919) famously makes a caveat concerning his doctrine of sense and reference: there are some special expressions like 'here', 'today' and 'that', that cannot by themselves express senses (and, therefore, cannot have references). Something else is necessary, namely, the extra-linguistic context in which the particular tokens of words of this kind occur. Therefore, i...

BSP trees and KD trees are fundamental data structures for collision detection in walkthrough environments. A basic issue in the construction of these hierarchical data structures is the choice of cutting planes. Rather than base these choices solely on the properties of the scene, we propose using information about how the tree is used in order to determine its structure. We demonstrate how th...

Kojima and Manea (2010) present two characterizations of when an allocation rule corresponds to the agent-proposing deferred acceptance algorithm for some substitutable priority rule of the objects being assigned. Building on their results we characterize when an allocation rule is outcome equivalent to the deferred acceptance algorithm for every substitutable priority rule. In particular, an a...

This paper presents Forward+, a method of rendering many lights by culling and storing only lights that contribute to the pixel. Forward+ is an extension to traditional forward rendering. Light culling, implemented using the compute capability of the GPU, is added to the pipeline to create lists of lights; that list is passed to the final rendering shader, which can access all information about...

rice is one of the most important staple cereals‏ ‏in iran and has a main role in providing ‎the food ‎security. harvesting by hand postpone the rice harvesting stage, and facing late season ‎rainfall, and increase of yield losses during harvesting. to determine the most suitable ‎harvesting method in gilan, three different harvesting methods (by hand, harvester and ‎combine) were considered as...

BACKGROUND As Japan's aging society needs more blood, young students comprise a progressively smaller portion of the donor pool. To ensure a safe and sustainable blood supply, it is crucial to select suitable donors. This study aims to evaluate donor deferral rates, causes of deferral, and characteristics of deferred Japanese students. METHODS Computerized records of blood centers in northern...

The study analyses the effect of tax avoidance, deferred expenses and liabilities on real earnings management. samples consist 152 manufacturing companies listed Indonesian Stock Exchange (IDX). examines financial statements from 2011 to 2019, ending up with 1,368 observations. empirical results this are as follows. First, avoidance affects positively abnormal discretionary operating cash flows...

The ears of young adult rabbits were painted with methylcholanthrene (MC) long enough to call forth a few benign tumors (papillomas, frill horns), and the animals were followed throughout their later lives. Soon after the paintings were stopped the tumors began to dwindle and vanished, yet even while they were disappearing other growths of the same kinds arose, only to vanish later in their tur...

the main purpose of this study is measuring and comparing of peanut harvesting loss in manual and mechanical methods in addition to economic analysis of them. hence, a field was selected in astaneh-ashrafiyeh and divided to three different plots. two plots were applied to measure mechanical harvesting loss and third one was applied for manual harvesting loss. according to test results, the lowe...
