First observation of Bs → J/ψf0(980) decays
No full textUsing data collected with the LHCb detector in proton–proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the system. Using a fit to the π+π− mass spectrum with interfering resonances gives . In the interval ±90 MeV around 980 MeV, corresponding to approximately two full f0 widths we also find , where in both cases the uncertainties are statistical and systematic, respectively
DETERMINANTS OF WHOLESALE BEEF-CUT PRICES
No full textKey determinants of monthly wholesale prices for 12 beef cuts include the quantity of the specific cut, stickiness in prices, marketing costs, quantities of pork and chicken, and seasonality. Seasonal patterns across the respective cuts are very different. Relative to the price in December, prices at the wholesale level in other months can be as much as 6 percent lower to as much as 21 percent higher.Wholesale prices, Beef cuts, Seasonality, Demand and Price Analysis, Livestock Production/Industries,
Effect of maternal restraint stress during gestation on temporal lipopolysaccharide-induced neuroendocrine and immune responses of progeny
No full textThe impact of gestational dam restraint stress on progeny immune and neuroendocrine temporal hormone responses to lipopolysaccharide (LPS) challenge was assessed. Maternal stress (5-min snout snare restraint stress during days 84 to 112 of gestation) increased (P \u3c 0.05) the magnitude of tumor necrosis factor (TNF)-α, interleukin-6, epinephrine (E), norepinephrine, and serum amyloid A (SAA) production following LPS infusion in the offspring. Moreover, these effects appear to be dependent on gender for TNF-α, E, and cortisol production. However, maternal stress did not affect (P \u3c 0.05) the normalization of proinflammatory cytokines or neuroendocrine hormones produced following LPS. Collectively, these results indicate that maternal stress impacts aspects of the proinflammatory cytokine and stress hormone response in their progeny following LPS dosing of the offspring. This response is potentially responsible in part for the resultant changes to SAA production. Because several of the changes observed here are dependent on pig gender, these results are also the first evidence that inherent epigenetic factors coupled with maternal stress impact the cumulative response to stress and LPS in young pigs
Anchoring effects in the development of false childhood memories
No full textWhen people receive descriptions or doctored photos of events that never happened, they often come to remember those events. But if people receive both a description and a doctored photo, does the order in which they receive the information matter? We asked people to consider a description and a doctored photograph of a childhood hot air balloon ride, and we varied which medium they saw first. People who saw a description first reported more false images and memories than people who saw a photo first, a result that fits with an anchoring account of false childhood memories
A computer based plant/soil aeration bibliography
No full textNumerous reviews of the general topic of plant and soil aeration
have appeared in the past generation. Two comprehensive recent
examples are Kozlowski(1984) and Glinski and Stepniewski (1985).
Each is excellently documented and thoroughly covers its subject
matter, though perhaps from somewhat divergent perspectives. As
might be expected the source of citations contained in each volume's bibliography largely reflects the geographical orientation and
principal area of expertise of the contributors. In each case,
undoubtedly, the authors compiled large collections of reprints and
second-source citations which were summarised and synthesised
into reviews. In the process, the authors characterised the citations of which they were aware, eliminated some of these from
final use in the reviews, and probably missed some citations in the
literature.
The nature of review writing, until only recently, has demanded that these efforts be largely individual, uncoordinated, tedious, and transitory (the work of collecting and compiling the
information is usually lost with the author's shift of interest,
retirement, or other activity-influencing career changes). Occasionally such a bibliography may be handed down from major
professor to student. Even in these cases, however, the bibliographies are not widely available.
The advent of computer-based information storage and retrieval has created new opportunities. Commercial literature retrieval services exist that scan organised data bases (e.g. SCI SEARCH* and DIALOG). Even with the continued expansion of the
data bases of these systems they have certain shortcomings. For
the unfamiliar users of these systems there is usually difficulty in
limiting the searches sufficiently to retrieve only desired citations
without excluding elusive citations that may be unconventionally
titled or that may not contain certain specific keywords needed to
retrieve the desired citations. Commercial literature retrieval can
also prove to be expensive for some users, particularly if a comprehensive retrospective search is desired.
If a subject matter area were sufficiently limited in scope it
could be possible for a few interested researchers cooperatively to
compile a highly comprehensive listing of the relevant literature. A
familiar example of such effort was the compilation of a bibliography on the topic of 15N by Hauck and Bystrom (1970). Their
bibliography, published as a book, provided an excellent fixed
resource, but one which lacked the capacity to grow or be manipulated. The advent of powerful microcomputers and inexpensive
data—base software now enables the compilation of highly specific
manipulable bibliographies. These bibliographies offer the advantages of being indexed by author, date, keywords, etc., of being
sorted by subcategories, and of being copied and shared in a
compact format (e.g. on floppy disk, tape, EPROM), and easily
updated and expanded
Identification of immunological biomarkers which may differentiate latent tuberculosis from exposure to environmental nontuberculous mycobacteria in children.
No full textA positive gamma interferon (IFN-γ) response to Mycobacterium tuberculosis early secretory antigenic target-6 (ESAT-6)/culture filtrate protein-10 (CFP-10) has been taken to indicate latent tuberculosis (TB) infection, but it may also be due to exposure to environmental nontuberculous mycobacteria in which ESAT-6 homologues are present. We assessed the immune responses to M. tuberculosis ESAT-6 and cross-reactive responses to ESAT-6 homologues of Mycobacterium avium and Mycobacterium kansasii. Archived culture supernatant samples from children at 3 years post-BCG vaccination were tested for cytokine/chemokine responses to M. tuberculosis antigens. Furthermore, the IFN-γ responses to M. tuberculosis antigens were followed up for 40 children at 8 years post-BCG vaccination, and 15 TB patients were recruited as a control group for the M. tuberculosis ESAT-6 response in Malawi. IFN-γ enzyme-linked immunosorbent assays (ELISAs) on supernatants from diluted whole-blood assays, IFN-γ enzyme-linked immunosorbent spot (ELISpot) assays, QuantiFERON TB Gold-In Tube tests, and multiplex bead assays were performed. More than 45% of the responders to M. tuberculosis ESAT-6 showed IFN-γ responses to M. avium and M. kansasii ESAT-6. In response to M. tuberculosis ESAT-6/CFP-10, interleukin 5 (IL-5), IL-9, IL-13, and IL-17 differentiated the stronger IFN-γ responders to M. tuberculosis ESAT-6 from those who preferentially responded to M. kansasii and M. avium ESAT-6. A cytokine/chemokine signature of IL-5, IL-9, IL-13, and IL-17 was identified as a putative immunological biosignature to differentiate latent TB infection from exposure to M. avium and M. kansasii in Malawian children, indicating that this signature might be particularly informative in areas where both TB and exposure to environmental nontuberculous mycobacteria are endemic
Fabrication of one-dimensional organic nanostructures using anodic aluminum oxide templates
No full textOrganic nanostructures are new comers to the fields of nanoscience and nanotechnology. In recent years novel methods for controlling the growth and uniformity of one-dimensional (1D) organic nanostructures (nanowires and nanotubes) have been developing. The use of hard templates as molds for the formation of organic nanowires or nanotubes seems to be a reliable and convenient method. In this review we will discuss the use of anodic aluminum oxide (AAO) templates as the inorganic hard template of choice. We will briefly survey advances in the fabrication of 1D polymer nanostructures using AAO templates, while the bulk of the review will focus on the synthesis of small molecule nanowires, nanotubes, and nanorods. We will also discuss unique properties of some highly crystalline small molecule nanorods fabricated using AAO templates.Al-Kaysi RO, 2006, CHEM COMMUN, P1224, DOI 10.1039-b516732a; ALKAYSI RO, 2009, J CRYSTAL GROWTH DES, V9, P1780; Al-Kaysi RO, 2008, J COLLOID INTERF SCI, V327, P102, DOI 10.1016-j.jcis.2008.07.040; Al-Kaysi RO, 2005, LANGMUIR, V21, P7990, DOI 10.1021-la051183b; Al-Kaysi RO, 2006, J AM CHEM SOC, V128, P15938, DOI 10.1021-ja064535p; Al-Kaysi RO, 2007, ADV MATER, V19, P1276, DOI 10.1002-adma.200602741; Al-Kaysi RO, 2007, MACROMOLECULES, V40, P9040, DOI 10.1021-ma0717082; Asoh H, 2001, J ELECTROCHEM SOC, V148, pB152, DOI 10.1149-1.1355686; Bai R, 2008, NANOTECHNOLOGY, V19, DOI 10.1088-0957-4484-19-05-055604; Barrett C, 2007, CHEM MATER, V19, P338, DOI 10.1021-cm0622654; Berdichevsky Y, 2006, ADV MATER, V18, P122, DOI 10.1002-adma.200501621; Briseno AL, 2008, MATER TODAY, V11, P38, DOI 10.1016-S1369-7021(08)70055-5; Cao G., 2004, NANOSTRUCTURES NANOM; Cepak VM, 1999, CHEM MATER, V11, P1363, DOI 10.1021-cm9811500; Cho SI, 2008, ACCOUNTS CHEM RES, V41, P699, DOI 10.1021-ar7002094; Freitas Jr R.

Re-evaluation of recombination losses in dye-sensitized cells: The failure of dynamic relaxation methods to correctly predict diffusion length in nanoporous photoelectrodes
No full textPhotocurrents generated by thick, strongly absorbing, dye-sensitized cells were reduced when the electrolyte Iodine concentration was increased. Electron diffusion lengths measured using common transient techniques (L n) were at least two times higher than diffusion lengths measured at steady state (L IPCE). Charge collection efficiency calculated using Ln seriously overpredicted photocurrent, while L IPCE correctly predicted photocurrent. This has implications for optimizing cell design. © 2009 American Chemical Society.Ahn KS, 2007, J APPL PHYS, V101, DOI 10.1063-1.2721976; Barnes PRF, 2009, J PHYS CHEM C, V113, P1126, DOI 10.1021-jp809046j; Barnes PRF, 2009, J PHYS CHEM C, V113, P12615, DOI 10.1021-jp904497c; Bisquert J, 2004, J PHYS CHEM B, V108, P2313, DOI 10.1021-jp035395y; Bisquert J, 2004, J PHYS CHEM B, V108, P2323, DOI 10.1021-jp035397i; Cao YM, 2009, J PHYS CHEM C, V113, P6290, DOI 10.1021-jp9006872; Chiba Y, 2006, JPN J APPL PHYS 2, V45, pL638, DOI 10.1143-JJAP.45.L638; de Jongh PE, 1996, PHYS REV LETT, V77, P3427, DOI 10.1103-PhysRevLett.77.3427; Dor S, 2009, J PHYS CHEM C, V113, P2022, DOI 10.1021-jp808175d; Dunn HK, 2009, J PHYS CHEM C, V113, P4726, DOI 10.1021-jp810884q; Fukai Y, 2007, ELECTROCHEM COMMUN, V9, P1439, DOI 10.1016-j.elecom.2007.01.054; Gao F, 2008, J AM CHEM SOC, V130, P10720, DOI 10.1021-ja801942j; Guo L, 2007, ACTA PHYS SIN-CH ED, V56, P4270; Halme J, 2008, J PHYS CHEM C, V112, P20491, DOI 10.1021-jp806512k; Halme J, 2008, J PHYS CHEM C, V112, P5623, DOI 10.1021-jp711245f; Hamann TW, 2008, J PHYS CHEM C, V112, P10303, DOI 10.1021-jp802216p; Heimer TA, 2000, J PHYS CHEM A, V104, P4256, DOI 10.1021-jp993438y; Huang SY, 1997, J PHYS CHEM B, V101, P2576, DOI 10.1021-jp962377q; Ito S, 2008, THIN SOLID FILMS, V516, P4613, DOI 10.1016-j.tsf.2007.05.090; Jennings JR, 2008, J AM CHEM SOC, V130, P13364, DOI 10.1021-ja804852z; Jennings JR, 2007, J PHYS CHEM C, V111, P16100, DOI 10.1021-jp076457d; Kang MS, 2008, J PHOTOCH PHOTOBIO A, V195, P198, DOI 10.1016-j.jphotochem.2007.10.003; Koops SE, 2009, J AM CHEM SOC, V131, P4808, DOI 10.1021-ja8091278; Kopidakis N, 2003, J PHYS CHEM B, V107, P11307, DOI 10.1021-jp0304475; Kopidakis N., 2006, PHYS REV B, V73, P7; Liu Y, 1998, SOL ENERG MAT SOL C, V55, P267, DOI 10.1016-S0927-0248(98)00111-1; Lobato K, 2006, J PHYS CHEM B, V110, P16201, DOI 10.1021-jp063919z; Madhwani S, 2007, ENERG SOURCE PART A, V29, P721, DOI 10.1080-00908310500280926; Nazeeruddin MK, 2004, LANGMUIR, V20, P6514, DOI 10.1021-la0496082; NAZEERUDDIN MK, 1993, J AM CHEM SOC, V115, P6382, DOI 10.1021-ja00067a063; Nelson I.

Intermittent millisecond x-ray pulsations from the neutron star x-ray transient SAX J1748.9-2021 in the globular cluster NGC 6440
No full textWe report on intermittent X-ray pulsations with a frequency of 442.36 Hz from the neutron-star X-ray binary SAX J1748.9-2021 in the globular cluster NGC 6440. The pulsations were seen during both 2001 and 2005 outbursts of the source, but only intermittently, appearing and disappearing on timescales of hundreds of seconds. We find a suggestive relation between the occurrence of type-I X-ray bursts and the appearance of the pulsations but the relation is not strict. This behavior is very similar to that of the intermittent accreting millisecond X-ray pulsar HETE J1900.1-2455. The reason for the intermittence of the pulsations remains unclear. However it is now evident that a strict division between pulsating and non-pulsating does not exist. By studying the Doppler shift of the pulsation frequency we determine an orbit with a period of 8.7 hrs and an projected semi major axis of 0.39 lightsec. The companion star might be a main-sequence or a slightly evolved star with a mass of ~1 Msun. Therefore, SAX J1748.9-2021 has a longer period and may have a more massive companion star than all the other accreting millisecond X-ray pulsars except for Aql X-1
