Force, quantum mechanics and approximate energy eigenstates (2008)

Das, C., Bhattacharyya, K.

The prevalent role of force in traditional quantum mechanics is outlined, with special reference to approximate calculations for stationary states. It will be explored how far this force concept can...

Structural arrest in an ideal gas (2005)

Ketel, W. Van, Das, C., Frenkel, D.

We report a molecular dynamics study of a simple model system that has the static properties of an ideal gas, yet exhibits nontrivial "glassy" dynamics behavior at high densities. The constituent...

Das, C, Kulkarni, P V, Constantinescu, A, Antich, P, Blattner, F R, Tucker, P W

We have produced a chimeric antibody (Ab) in which metallothionein, a well-characterized biological chelator of metals, was genetically fused to the F(ab') domain of the S107 Ab heavy chain....

Isoimmunization against human chorionic gonadotropin with conjugates of processed beta-subunit of the hormone and tetanus toxoid.

Talwar, G P, Sharma, N C, Dubey, S K, Salahuddin, M, Das, C, Ramakrishnan, S, ...

The immunogenicity of the conjugate prepared from "processed" beta-subunit of human chorionic gonadotropin (choriogonadotropin, HCG) and tetanus toxoid has been studied in animals and a human...

Novel protein-DNA interactions associated with increased immunoglobulin transcription in response to antigen plus interleukin-5.

Webb, C F, Das, C, Eaton, S, Calame, K, Tucker, P W

Identification of a matrix-associated region 5' of an immunoglobulin heavy chain variable region gene.

Webb, C F, Das, C, Eneff, K L, Tucker, P W

In the accompanying report (C. F. Webb, C. Das, S. Eaton, K. Calame, and P. Tucker, Mol. Cell. Biol. 11:5197-5205, 1991), we characterize B-cell-specific protein-DNA interactions at -500 and -200 bp...

A practicable immunological approach to block spermatogenesis without loss of androgens.

Talwar, G P, Naz, R K, Das, C, Das, R P

The intrinsic capacity of the immune system to elicit immune response selectively against late developing sperm proteins has been mobilized to intercept spermatogenesis. Bacillus Calmette-Guérin...

Recognition of the beta-subunit of human chorionic gonadotropin and sub-determinants by target tissue receptors.

Ramakrishnan, S, Das, C, Talwar, G P

The beta-subunit of human chorionic gonadotropin, purified immunochemically to eliminate undissociated human chorionic gonadotropin, induced testosterone production by mouse Leydig cells at...
