ACRL Remains Largest Division

16-899C ACRL Tetris Reinforcement Learner

Our approach to this problem was to use reinforcement learning with a function approximator to approximate the state value function [RSS98]. In our case, a +1 reward was given for every completed line, so that the value function would encode the long-term number of lines that is going to be completed by the algorithm. In order to achieve this, we extract features from the game state, and use gr...

Endoplasmic reticulum remains continuous and undergoes sheet-to-tubule transformation during cell division in mammalian cells

The endoplasmic reticulum (ER) is a multifaceted cellular organelle both structurally and functionally, and its cell cycle-dependent morphological changes are poorly understood. Our quantitative confocal and EM analyses show that the ER undergoes dramatic reorganization during cell division in cultured mammalian cells as mitotic ER profiles become shorter and more branched. 3D modeling by elect...

The Krapina dental remains.

An analysis of age, specimen associations, demographic characteristics, and metric features is presented for the Krapina dental sample. A critical analysis of emergence criteria applicable to skeletal samples leads to an occlusal eruption schedule which can be used to determine wear rates. These are used to provide dental ages for the Krapina jaws and isolated teeth. A number of individual asso...

Identification of Skeletal Remains

Phosphorus remains exciting!

Today, the search for new element modifications is basically characterized by work under extreme conditions, in particular, high pressures and very often high temperatures. This situation is not surprising since the discovery of new elements and their characterization under normal conditions is more a topic of chemical-historical literature. Despite this, surprises are still found in the area o...
