research interests have been focused on the concept of penalizing jobs both for being early and for being tardy because not only of modern competitive industrial challenges of providing a variety of products at a very low cost by smoothing productions but also of its increasing and exciting computer applications. here, sequencing approaches of the mixed- model just-in-time production systems is...

an improved mixed order model is presented to describe the thermolumunescence (tl) glow peaks. in this model a fraction of charge carriers, which undergo nonradiative recombination following thermal excitation is taken into account. therefore, it is expected that the proposed model will produce more realistic kinetic parameters than that of mixed order model. the tl glow curves generated by the...

Chordoma is a rare, radiation-resistant, skull-base and spinal tumor with high local recurrence containing mixed cell-adhesion phenotypes. We characterized DNA damage response (DDR) signaling (γH2AX, pKAP1, pATM) and survival response to ionizing radiation (IR) in human chordoma samples (42 resections, 23 patients) to test if blocking cell adhesion sensitizes U-CH1 tumor cells to IR. U-CH1 cell...

We revisit 't Hooft anomalies in (1+1)$d$ non-spin quantum field theory, starting from the consistency and locality conditions, find that consistent U(1) gravitational cannot always be canceled by properly quantized (2+1)$d$ classical Chern-Simons actions. On one hand, we prove certain exotic can only realized non-reflection-positive or non-compact theories; on other without insisting reflectio...

We present a new construction of non-classical unitals from a classical unital U in PG(2, q2). The resulting non-classical unitals are B-M unitals. The idea is to find a non-standard model Π of PG(2, q2) with the following three properties: (i) points of Π are those of PG(2, q2); (ii) lines of Π are certain lines and conics of PG(2, q2); (iii) the points in U form a non-classical B-M unital in ...

To understand the control of glial tumor cell proliferation, we have examined the effects of neurons on a number of human and rodent glioma lines. These included C6, G26-24, U-251, HTB-16, and A-172 cells of astroglial lineage and G26-20 of bipotential astrocytic and oligodendrocytic lineage. Rapid, specific binding of granule neurons to the human A-172, HTB-16, and U-251 and mouse G26-24 cell ...

Interval graphs, intersection graphs of segments on a real line (intervals), play key role in the study algorithms and special structural properties. Unit interval their proper subclass, where each has unit length, also been extensively studied. We mixed graphs---a generalization still but intervals more than one type (open, closed, semi-closed) are allowed. This small modification captures muc...
