Polaron cross-overs and d-wave superconductivity in Hubbard-Holstein model
We present a theoretical study of superconductivity of polarons in the
Hubbard-Holstein model. A residual kinematic interaction proportional to the
square of the polaron hopping energy between polarons and phonons provides a
pairing field for the polarons. We find that superconducting instability in the
d-wave channel is possible with small transition temperatures which is maximum
in the large to small polaron cross-over region. An s-wave instability is found
to be not possible when the effective on-site interaction between polarons is
repulsive
A short note on the joint entropy of n/2-wise independence
In this note, we prove a tight lower bound on the joint entropy of
unbiased Bernoulli random variables which are -wise independent. For
general -wise independence, we give new lower bounds by adapting Navon and
Samorodnitsky's Fourier proof of the `LP bound' on error correcting codes. This
counts as partial progress on a problem asked by Gavinsky and Pudl\'ak.Comment: 6 pages, some errors fixe
Leader humility and knowledge sharing intentions: A serial mediation model
Purpose: This paper examines the influence of leader humility on knowledge sharing intention. Drawing on social exchange theory (SET), we test the direct and indirect mechanisms to explain the influence leader humility has on knowledge sharing intention.
Design/Methodology/Approach: A two-wave, time-lagged field study was conducted. We surveyed 252 professional employees from Australia.
Findings: Results show a significant direct, positive association between leader humility and knowledge sharing intention. While leader humility had a direct, positive association with affective trust in supervisor and work engagement, it did not directly impact on organizational citizenship behaviors directed toward the individual (OCB-I). There were three SET-related, serial mediators in the relationship between leader humility and knowledge sharing intention. These were affective trust, work engagement, and OCB-I.
Research Limitations/Implications: Future studies should collect multi-source data such as peers’ or supervisors’ ratings of the focal respondents’ work engagement, OCB-I, and knowledge sharing behaviors to augment single-source data. Future studies could adopt an affect theory of social exchange to further explore the relationships tested in this study.
Originality/Value: This study contributes to the affect SET and knowledge management literature on how leadership behaviors impact the intention to share knowledge. Our study highlights the preference of the willingness to share knowledge with their co-workers is mediated by affective trust in their immediate supervisors, work engagement, and OCB-I that are equally important as treating their subordinates with humility
Population dynamics of cobia Rachycentron canadum (Linnaeus, 1766) off Cochin coast, south-eastern Arabian Sea
Estimated landings of cobia from the Indian EEZ by the commercial fishing vessels are mostly as bycatch in hooks and line
cum gillnet and trawl nets. However, the catches are substantial compared to that reported in several other countries of Asia.
The species is also gaining considerable importance as a favoured candidate species for sea farming using cages. Very little
is known about the fishery and biological characters such as maturation, fecundity and feeding preferences of cobia in Indian
seas. Study indicated a fast growth rate with estimates of L∞ = 184 cm (FL) and K = 2.6 (yr-1) in cobia. The total mortality rate
(Z) was estimated as 5.18, natural mortality (M) was 2.01 and fishing mortality (F) was 3.17 with an exploitation rate (E) of
0.61. The length at first capture (Lc50) estimated from the catch curve was 72 cm. Fecundity was found to be high and
variable, with mean fecundity estimated as 12,37,545 eggs with a coefficient of variation (CV) of 16.7. As inferred from the
oocyte development pattern, spawning activity is brief and fish is classified as synchronous ovulatory type. The growth
parameters and condition factor estimated in this study indicate that relatively high growth rates are also possible in wild
stocks considering that food is abundant and the environmental temperature is in the optimum range. Feeding
preferences indicated balistid fish and shrimps with a wide variety of food items including finfishes, crustaceans and molluscs

Spin-Peierls instability in a quantum spin chain with Dzyaloshinskii-Moriya interaction
We analysed the ground state energy of some dimerized spin-1/2 transverse XX
and Heisenberg chains with Dzyaloshinskii-Moriya (DM) interaction to study the
influence of the latter interaction on the spin-Peierls instability. We found
that DM interaction may act either in favour of the dimerization or against it.
The actual result depends on the dependence of DM interaction on the distortion
amplitude in comparison with such dependence for the isotropic exchange
interaction.Comment: 12 pages, latex, 3 figure
New records of Champsodon nudivittis and Champsodon snyderi (Fam: Champsodontidae) from the Indian EEZ
Champsodon genus belonging to the family
Champsodontidae are constituted by bottom
dwelling fishes at great depths (400 – 1000 m) in
the oceans and are commonly referred to as gapers.
These are characterized by a large head and mouth,
an elongate compressed body densely covered with
small denticulate scales, pre-opercle with a
prominent postero-ventral spine bearing small
serrations on the ventral side, a short spinous dorsal
fin, small pectoral fins, unusually large pelvic fins
and a complex acoustic-lateralis system that
consists of two horizontal lateral lines
interconnected by vertical rows of sensory papillae
New record of the gaper Champsodon nudivittis (Ogilby, 1895) from the deep waters of north-east Arabian Sea with notes on its biology
The gaper Champsodon nudivittis is reported as the first record of the species in the northern Arabian Sea where it was
caught at 280 -390 m depths between 19 and 210 N latitudes. Study confirmed the presence of a sizeable self-regenerating
population of C. nudivittis in the northern Arabian Sea comprising of reproductively active, mature fish, which was believed
to be absent so far. The size range of the specimens caught was 55-105 mm with modal size 75-85 mm. Females were
significantly dominant (p 60 mm size groups, with a sex ratio of 1:4.3. Catch was dominated by mature females,
with an estimated Lm of 74 mm. Mean absolute fecundity was 740±156 eggs and mean relative fecundity 205±97 eggs per
gram body weight. It is a carnivorous predator, feeding on young of several commercially important fishery resources such
as the pandalid shrimps, sergestid shrimps (Acetes) and the Indian codlet Bregmaceros spp. found in the northern Arabian
Sea
Frustration induced Raman scattering in CuGeO_3
We present experimental data for the Raman intensity in the spin-Peierls
compound CuGeO_3 and theoretical calculations from a one-dimensional frustrated
spin model. The theory is based on (a) exact diagonalization and (b) a recently
developed solitonic mean field theory. We find good agreement between the
1D-theory in the homogeneous phase and evidence for a novel dimerization of the
Raman operator in the spin-Peierls state. Finally we present evidence for a
coupling between the interchain exchange, the spin-Peierls order parameter and
the magnetic excitations along the chains.Comment: Phys. Rev. B, Rapid Comm, in Pres
