We test a pentaquark model of the negative parity hyperon Λ(1405). We use the model where valence four quarks and one antiquark move in a potential relativisticaly and interact with themselves and each other through gluon and NG boson. We calculate mass shift of the system and find that there are two Λ(1405) with almost degenerate mass: one flavor singlet and one flavor octet. We calclate also ...
UNLABELLED Prostate-specific membrane antigen (PSMA) is a well-established target for developing radiopharmaceuticals for imaging and therapy of prostate cancer (PCa). We have recently reported that novel (99m)Tc-labeled small-molecule PSMA inhibitors bind with high affinity to PSMA-positive tumor cells in vitro and localize in PCa xenografts. This study reports the first, to our knowledge, hum...
The first general Zagreb index is defined as $M_1^lambda(G)=sum_{vin V(G)}d_{G}(v)^lambda$. The case $lambda=3$, is called F-index. Similarly, reformulated first general Zagreb index is defined in terms of edge-drees as $EM_1^lambda(G)=sum_{ein E(G)}d_{G}(e)^lambda$ and the reformulated F-index is $RF(G)=sum_{ein E(G)}d_{G}(e)^3$. In this paper, we compute the reformulated F-index for some grap...
Let $P(lambda)$ be an $n$-square complex matrix polynomial, and $1 leq k leq n$ be a positive integer. In this paper, some algebraic and geometrical properties of the $k$-numerical range of $P(lambda)$ are investigated. In particular, the relationship between the $k$-numerical range of $P(lambda)$ and the $k$-numerical range of its companion linearization is stated. Moreover, the $k$-numerical...
