Two photon annihilation operators and squeezed vacuum
Inverses of the harmonic oscillator creation and annihilation operators by their actions on the number states are introduced. Three of the two photon annihilation operators, viz., a(sup +/-1)a, aa(sup +/-1), and a(sup 2), have normalizable right eigenstates with nonvanishing eigenvalues. The eigenvalue equation of these operators are discussed and their normalized eigenstates are obtained. The Fock state representation in each case separates into two sets of states, one involving only the even number states while the other involving only the odd number states. It is shown that the even set of eigenstates of the operator a(sup +/-1)a is the customary squeezed vacuum S(sigma) O greater than
Iskorištavanje hrane, metaboliti u krvi i ponašanje pri unosu hrane u teladi sahival pasmina odabrane s obzirom na visoki ili niski ostatni unos hrane
This study aimed to evaluate differences in feed utilization between low and high residual feed intake (RFI) in Sahiwal calves by comparing performance, ingestive behavior and blood metabolites. Eighteen, growing, female Sahiwal calves (aged 10-14 months; body weight (BW) 100-125 kg) were fed ad libitum on a total mixed ration for 90 d. RFI varied from -0.53 to 0.40 kg dry matter (DM)/d with a mean RFI of -0.27 to 0.17 kg DM/d in low and high RFI Sahiwal calves, respectively. Calves with low RFI consumed 26% less DM and required 35% less metabolizable energy for body maintenance (MEm) compared to high RFI, yet gained at a similar rate. Low RFI calves digest feed more efficiently than less efficient calves. Conventional efficiency measures also showed better efficiency in low RFI than high RFI calves. Low RFI calves spent less time in feeding, rumination, and chewing. Higher plasma concentrations of insulin-like growth factor-1 (IGF-1), growth hormone (GH), and creatinine, and lower concentrations of albumin, plasma urea nitrogen (PUN), and triglycerides were observed in the low RFI group than the high RFI group. However, plasma total protein, glucose, cholesterol, non esterified fatty acid (NEFA), beta-hydroxy butyric acid (BHBA), calcium (Ca), and phosphorus (P) concentrations were similar in both groups. In summary, low RFI calves utilized feed more efficiently by spending less time and energy in feeding, and the variability in blood metabolites might be due to differences in body metabolism.Ovo istraživanje imalo je za cilj, na temelju proizvodnje, ponašanja kod unosa hrane i metabolita u krvi, procijeniti razlike u iskorištavanju hrane između sahival teladi s niskim ostatnim unosom hrane i visokim ostatnim unosom hrane (Residual Feed Intake - RFI). Osamnaest sahival teladi ženskog spola (u dobi od 10 do -14 mjeseci i tjelesnoj masi od 100 do 125 kg) hranjeno je 90 dana, ad libitum, kompletnim mješovitim obrokom. Ostatni unos hrane kretao se od -0,53 do 0,40 kg suhe tvari/d, sa srednjom vrijednošću od -0,27 kod sahival teladi s niskim ostatnim unosom i srednjom vrijednošću od 0,17 kg kod sahival teladi visokim ostatnim unosom hrane. Iako je telad s niskim ostatnim unosom hrane u odnosu na onu s visokim ostatnim unosom hrane konzumirala 26% manje suhe tvari i zahtijevala 35 % manje uzdržne energije za metabolizam tijela, prirast obje skupne teladi kretao se po sličnoj stopi. Telad s niskim ostatnim unosom hrane imala je učinkovitiju hranidbu što su pokazali i standarni pokazatelji prema kojima je ta telad provela hranidbu u kraćem vremenu, uz kraće žvakanje i preživanje. U usporedbi s teladi koja ima viši ostatni unos hrane, telad s niskim ostatnim unosom hrane imala je u plazmi veće koncentracije inzulinu-sličnog faktora rasta-1 (IGF-1), hormona rasta (GH) i kreatinina, te niže koncentracije albumina, dušika iz ureje i triglicerida. Koncentracije ukupnih proteina, glukoze, kolesterola, neesterificirane masne kiseline (NEFA), betahidroksi maslačne kiseline (BHBA), kalcija (Ca) i fosfora (P) bile su slične u obje skupine teladi. Sažeto, telad s niskim ostatnim unosom hrane iskorištavala je hranu učinkovitije, provodeći kraće vrijeme i trošeći manje energije prilikom hranjenja, a varijacije metabolita u krvi mogle bi biti posljedica razlika u metabolizmu

Genome wide association study of uric acid in Indian population and interaction of identified variants with type 2 diabetes
Abnormal level of Serum Uric Acid (SUA) is an important marker and risk factor for complex diseases including Type 2 diabetes. Since genetic determinant of uric acid in Indians is totally unexplored, we tried to identify common variants associated with SUA in Indians using Genome Wide Association Study (GWAS). Association of five known variants in SLC2A9 and SLC22A11 genes with SUA level in 4,834 normoglycemics (1,109 in discovery and 3,725 in validation phase) was revealed with different effect size in Indians compared to other major ethnic population of the world. Combined analysis of 1,077 T2DM subjects (772 in discovery and 305 in validation phase) and normoglycemics revealed additional GWAS signal in ABCG2 gene. Differences in effect sizes of ABCG2 and SLC2A9 gene variants were observed between normoglycemics and T2DM patients. We identified two novel variants near long non-coding RNA genes AL356739.1 and AC064865.1 with nearly genome wide significance level. Meta-analysis and in silico replication in 11,745 individuals from AUSTWIN consortium improved association for rs12206002 in AL356739.1 gene to sub-genome wide association level. Our results extends association of SLC2A9, SLC22A11 and ABCG2 genes with SUA level in Indians and enrich the assemblages of evidence for SUA level and T2DM interrelationship
An advanced draft genome assembly of a desi type chickpea (Cicer arietinum L.)
Chickpea (Cicer arietinum L.) is an important pulse legume crop. We previously reported a draft genome assembly of the desi chickpea cultivar ICC 4958. Here we report an advanced version of the ICC 4958 genome assembly (version 2.0) generated using additional sequence data and an improved genetic map. This resulted in 2.7-fold increase in the length of the pseudomolecules and substantial reduction of sequence gaps. The genome assembly covered more than 94% of the estimated gene space and predicted the presence of 30,257 protein-coding genes including 2230 and 133 genes encoding potential transcription factors (TF) and resistance gene homologs, respectively. Gene expression analysis identified several TF and chickpea-specific genes with tissue-specific expression and displayed functional diversification of the paralogous genes. Pairwise comparison of pseudomolecules in the desi (ICC 4958) and the earlier reported kabuli (CDC Frontier) chickpea assemblies showed an extensive local collinearity with incongruity in the placement of large sequence blocks along the linkage groups, apparently due to use of different genetic maps. Single nucleotide polymorphism (SNP)-based mining of intra-specific polymorphism identified more than four thousand SNPs differentiating a desi group and a kabuli group of chickpea genotypes

Indian explosions of 11 May 1998: analysis of regional Lg and Rayleigh waves
This paper presents the analysis of regional Lg and Rayleigh wave data pertaining to the Indian explosions of 11 May 1998 (POK2). Strong Lg and Rayleigh waves have been recorded at several in-country stations. A comparison of Lg waves at Gauribidanur array (GBA), India corresponding to POK2 and that of the Indian explosion of May 1974 (POK1) shows an amplitude ratio of 3.7 between these events. This leads to a yield ratio of 4.83 between the two events. Analysis of Rayleigh waves revealed that Nuttli’s relation for estimation of surface wave magnitude (Ms) in the period range 3.0–12.0 s based on eastern North American data is also applicable for the Indian region. The average Ms value of POK2 from regional data is obtained as 3.56. The yield estimate of POK2 as obtained from the regional data analysis is found consistent with our earlier findings and the post shot radiochemical measurements
‘It Takes Two Hands to Clap’: How Gaddi Shepherds in the Indian Himalayas Negotiate Access to Grazing
This article examines the effects of state intervention on the workings of informal institutions that coordinate the communal use and management of natural resources. Specifically it focuses on the case of the nomadic Gaddi
shepherds and official attempts to regulate their access to grazing pastures in the Indian Himalayas. It is often predicted that the increased presence of the modern state critically undermines locally appropriate and community-based resource management arrangements. Drawing on the work of Pauline Peters and Francis Cleaver, I identify key instances of socially embedded ‘common’ management institutions and explain the evolution of these arrangements
through dynamic interactions between individuals, communities and the agents of the state. Through describing the ‘living space’ of Gaddi shepherds across the annual cycle of nomadic migration with their flocks I explore the
ways in which they have been able to creatively reinterpret external interventions, and suggest how contemporary arrangements for accessing pasture at different moments of the annual cycle involve complex combinations of the
formal and the informal, the ‘traditional’ and the ‘modern’
