Minimum Bias Triggers at ATLAS, LHC
In the first phase of LHC data-taking ATLAS will measure the charged-particle
density at the initial center-of-mass energy of 10 TeV and then at 14 TeV. This
will allow us improve our knowledge of soft QCD models and pin-down
cross-sections of different classes of inelastic collisions at LHC energies. In
particular, the dominant non-diffractive interaction is a key process to
understanding QCD backgrounds when we reach higher luminosities. We highlight
two minimum-bias triggers, sensitive to particles in complementary ranges in
pseudo-rapidity, one based on signals from the Inner Detector, the other
explicitly designed to trigger on inelastic processes. Studies of their trigger
efficiencies as well as possible trigger biases are presented.Comment: 3 pages, 4 figures, poster proceedings for ICHEP 200
pi N to Multi-pi N Scattering in the 1/N_c Expansion
We extend the 1/N_c meson-baryon scattering formalism to pi N to multi-pi N
case. We first show that the leading-order large N_c processes proceed through
resonant intermediate states (e.g., rho N or pi Delta). We find that the pole
structure of baryon resonances can be uniquely identified by their
(non)appearance in eta N or mixed partial-wave pi Delta final states.Comment: Invited talk at Exclusive Reactions at High Momentum Transfer

Effect of Quality of Wheat and Maize Flour in Tempura Batter
**This is a metadata-only record**
Due to a technical issue the file(s) associated with this record are no longer available. We apologise for the inconvenience.
Record updated on 26.04.2016 by EMA (TIS).Tempura batters are stand-alone systems that are not further breaded. They provide a protective
coating which can range in texture from crispy/crunchy to cake-like. Recipes for batter systems are
adjusted empirically, and the choice of ingredients, especially flour, will determine the quality and
acceptability of coating. This study aims to characterise wheat and maize flours that would optimise
fried tempura quality, and to study their effect on behaviour of batters, and quality of fried products.
In aqueous ethanol, results showed RVA to be useful to characterise wheat flours for batter
applications. There is a close relationship between flour attributes and flour starch pasting behaviour.
Positive correlation was found between 1st peak viscosity (starch) and 2nd peak viscosity (protein) (r
= 0.768). Farinograph and Extensograph data were correlated to RVA, but of minimum use for flour
batter functionality due to the absence of a gluten network. Maize plays a strong role in batter
viscosity control, and various viscosity measuring methods were applied. Empirical methods were
easy and rapid, but arbitrary, subjective and not precise. Imitative tests were an improvement, but
less precise than rheometry. The BS cup method was more accurate at 50ml than at 70ml, and they
were positively correlated (r2 = 0.99). Back extrusion (BE) data showed a strong correlation with
CFS and BS cups measurement. Using Pearson correlation analyses, positive correlations were
found between viscosity from BS Cup and firmness (r = 0.851), BS cup and consistency (r =
0.891), CFS cup and firmness (r = 0.74), and CFS cup and consistency (r = 0.768). Therefore,
BE is recommended as an alternative to the above. Maize flour pasting properties varied with the
flour particle size. Peak viscosity correlates negatively with particle size (r = -0.959), and positively
with starch damage (r = 0.83). Rheology of different flour combinations in tempura batter was
studied, and links between texture parameters in relation of flour type and concentration were
established, and can be used to guide development/selection of wheat and maize flour for batters.
An electron microscopy low vacuum low temperature SEM method was used successfully to
visualise the microstructure of a range of deep-fried battered chicken samples linked to specific
formulations which established links between structure and function, and eating qualities.
Sensory evaluation of texture discriminated between coatings on chicken pieces, and was consistent
to instrumental analysis, i.e. extended Kraft knife on crust and core while simultaneously measuring
the sound pressure level of the emitted sound. Acoustic parameters extracted from the compression
curves were useful. Positive correlations were found between breading crispness with No. force
peaks and No. sound peaks, i.e. r = 0.749 and r = 0.693 respectively. Moisture and fat contents of
the core and crust were related to the texture, but exceptions were linked to very dissimilar crispness;
which would depend on water distribution within the crust. Ease of breakdown on the mouth
contributes to preferences of texture. More work on the interaction between wheat and maize flours,
and batter rheological, thermal, and textural properties, will further this project’s significant
contribution to the knowledge of the effects of flours selection and formulation on batter technology
and coated product quality.Kerry Ingredient
The House of Kwee Sik Poo an Indonesian-Chinese Merchant From Pasuruan
The Kwee family is an old Indonesian-Chinese family from Pasuruan, in East Java, and one of a few merchant families of either Chinese or Arab ethnic origin which led successful lives in this small town in the nineteenth century. From their Chinese ancestral village, Liu Chuan in Fujian province, China, a Kwee ancestor travelled to Southeast Asia and settled in Pasuruan, probably in the eighteen century. As with many families who held important positions in the ethnic Chinese community, it also owned large homes, mostly in a mixed architectural style, called “eclecticism” and later in what was known as “the Indies-empire style”. The early family history is still clouded in mystery, as not much concrete information has survived. Its descendants worked hard and prospered and dealt among economic undertakings such as sugar production, opium sales, buying and selling of property and land as well as running pawnshops
Regulation of NF-κB activity through lysine monomethylation of p65
NF-κB is a key activator of inflammatory and immune responses with important pathological roles in cancer, heart disease, and autoimmune diseases. Transcriptional activity of NF-κB is regulated by different posttranslational modifications. Here, we report a novel mechanism of NF-κB regulation through lysine monomethylation by SET9 methyltransferase. Set9 specifically methylates p65 at lysine 37. Both TNFα and IL-1β treatments induced methylation of p65. Methylated p65 is restricted to the nucleus and this modification regulates the promoter binding of p65. Moreover, Set9 mediated methylation of p65 is required for the expression of a subset of NF-κB target genes in response to TNFα stimulation
Gradient-based Reinforcement Planning in Policy-Search Methods
We introduce a learning method called ``gradient-based reinforcement
planning'' (GREP). Unlike traditional DP methods that improve their policy
backwards in time, GREP is a gradient-based method that plans ahead and
improves its policy before it actually acts in the environment. We derive
formulas for the exact policy gradient that maximizes the expected future
reward and confirm our ideas with numerical experiments.Comment: This is an extended version of the paper presented at the EWRL 2001

1/N_c Corrections in Meson-Baryon Scattering
Corrections to meson/ground-state baryon scattering amplitudes in the 1/N_c
expansion of QCD have previously been shown to be controlled by the t-channel
difference |I_t - J_t| of isospin and angular momentum and by the change of
hypercharge Y_t. Here we derive the corresponding expressions in the original
scattering s channel, allowing for nonzero meson spin and nontrivial SU(3)
flavor quantum numbers, and provide explicit examples of the crossing relevant
for pi N --> rho N and K N scattering.Comment: Addition of a physical example, minor changes to clarify certain
issues and add one reference. 18 pages, no figure
Mapping the cancer imaging research landscape:which cancers are more and which cancers are less frequently investigated?
Objective: To investigate the proportion of published imaging studies relative to incidence and mortality rate per cancer type. Methods: From a random sample of 2500 articles published in 2019 by the top 25 imaging-related journals, we included cancer imaging studies. The publication-to-incidence and publication-to-mortality ratios (defined as the publication rate divided by the proportional incidence and mortality rate, respectively) were calculated per cancer type. Ratios >1 indicate a higher publication rate compared to the relative incidence or mortality rate of a specific cancer. Ratios 2, whereas nonmelanoma of the skin, leukemia, stomach cancer, and laryngeal cancer had publication-to-incidence ratios 2, whereas esophageal cancer, stomach cancer, laryngeal cancer, and leukemia had publication-to-mortality ratio
