WB Yeats: No Country for Old Men

I originated, developed and wrote this one-hour documentary for RTE Television on newly discovered aspects of the life of WB Yeats. I am credited as producer and co-writer.

JR WB ba

Brown sediment with clasts ranging from small to large in size. Clast shape ranges from angular to sub-rounded. Rotation structures are common in this sample, especially around larger clasts. Lineations and grain crushing is also present within this sample. A few comet structures can also be seen.

J.R WB-3a

Brown sediment with two main domains; a coarse grained domain and a fine grained domain. Clast size in the fine grained domain is mainly small. The coarser domain contains clasts ranging from small to large in size. The clast shape ranges from angular to rounded. Necking structures are commonly seen in the coarser domain. This domain also contains many rotation structures and lineations. The fine grained domain exhibits multiple water escape pathways, along with lineations. There are also minor amounts of grain crushing present within this sample.

J.R WB-6c

Brown sediment with clasts ranging from small to large in size. Grain shape ranges from angular to rounded. Lineations are abundant within this sample. Rotation structures can also be seen. Necking structures, comet structures, and grain crushing can also be seen in minor amounts.

J.R WB-7a

Brown sediment with clasts ranging from small to large. Grain shape ranges from angular to rounded. Rotation structures and necking structures are common throughout this sample. Lineations can also be seen throughout the sample, along with minor amounts of grain crushing and comet structures.

J.R. WB-2

Dark brown sediment with clasts ranging from small to large. Clast shape ranges from angular to rounded. Comet structures and lineations can be commonly seen throughout the sample. There are minor amounts of rotation structures also present. The sample contains clasts that are generally well dispersed.

WB-3b

Dark brown sediment with well dispersed clasts. The clasts range from small to large in size and sub-angular to sub-rounded in shape. The sample is abundant in rotation structures and lineations. It also contains comet structures and minor amounts of grain stacking.

WB-4

Brown sediment with clasts ranging from small to large in size. Clast shape ranges from sub-angular to sub-rounded. Rotation structures are abundant in this sample. They are seen around small and large clasts. A few necking structures can also be seen. These typically occur between larger aggregates. Lineations, comet structures, and grain crushing can also be seen in minor amounts.

WB-6a

Brown sediment with clasts ranging from small to large in size. Clast shape ranges from angular to sub-rounded. Necking structures are abundant within this sample, mainly between larger aggregates. Some rotation structures and lineations can also be seen. Comet structure and grain stacking can be seen in minor amounts.

WB-6b

Dark brown sediment with clasts ranging from small to large in size. Grain shape ranges from sub-angular to rounded. Rotation structures are common throughout the sample. Some necking structures are also present between large and medium sized aggregates. Lineations and grain stacks are also present in minor amounts.

WB-7b

Dark brown sediment with clasts ranging from small to large in size. The grains range from sub-angular to sub-rounded in shape. Rotation structures and necking structures can commonly be seen throughout. Lineations and comet structures can also be seen throughout the sample. Grain crushing can be seen in minor amounts in several areas.

WB-I

Dark brown sediment with two domains. One domain is fine grained, while the other is coarser grained. Clasts range from small to large, and sub-angular to sub-rounded in shape. The coarser domain contains lineations, comet structures and minor amounts of rotation structures. The fine grained domain is abundant with water escape structures. This sample also contains a few different areas of clay rich sediment.

Measurement of beta (t -> Wb)/beta(t -> Wq) at root s=1.96 TeV

We present the measurement of R = B(t -> Wb)/B(t -> Wq) in pp collisions at root s = 1.96 TeV, using 230 pb(-1) of data collected by the DO experiment at the Fermilab Tevatron Collider. We fit simultaneously R and the number (N-tt) of selected top quark pairs (tt), to the number of identified b-quark jets in events with one electron or one muon, three or more jets, and high transverse energy imbalance. To improve sensitivity, kinematical properties of events with no identified b-quark jets are included in the fit. We measure R = 1.03(-0.17)(0.19) (stat + syst), in good agreement with the standard model. We set lower limits of R > 0.61 and vertical bar V-tb vertical bar > 0.78 at 95% confidence level.

Simultaneous measurement of the ratio R = B(t -> Wb)/B(t -> Wq) and the top-quark pair production cross section with the D0 detector at root s=1.96 TeV

We present the first simultaneous measurement of the ratio of branching fractions, R = B(t --> Wb)/B(t --> Wq), with q being a d, s, or b quark, and the top-quark pair production cross section sigma(t (t) over bar) in the lepton plus jets channel using 0.9 fb(-1) of p (p) over bar collision data at root s = 1.96 TeV collected with the D0 detector. We extract R and sigma(t (t) over bar) by analyzing samples of events with 0, 1, and >= 2 identified b jets. We measure R = 0.97(-0.08)(+0.09) (stat + syst) and sigma(t (t) over bar) = 8.18(-0.84)(+0.90) (stat + syst) +/- 0.50(lumi) pb, in agreement with the standard model prediction.
