For the first time we search for $\eta_{c2}(1D)$ in $e^+e^-\to\gamma\eta_{c2}(1D)$ at $\sqrt{s}$ = 10.52, 10.58, and 10.867 GeV with data samples of 89.5 fb$^{-1}$, 711 121.4 respectively, accumulated Belle detector KEKB asymmetric energy electron-positron collider. No significant signal is observed mass range between 3.8 3.88 GeV/$c^2$. The upper limit 90\% confidence level on product Born cro...

Information age organizations must effectively utilize new communications capabilities to gain an advantage over their competition. Command and Control (C2) research has demonstrated the potential for decentralization of C2 to improve mission performance in networked battlefields. However, it is unlikely that all future missions will be best executed with a decentralized C2 architecture. Theref...

OBJECTIVE The optimal treatment modality for traumatic spondylolisthesis of the axis is still a controversial issue. Many conservative, posterior and anterior fixation techniques have been used to treat these injuries. The C2 pars (isthmus) was used as a novel screw anchor point in upper cervical spine injuries. The direct C2 pars screws are also used to fixate the posterior and anterior parts ...

LetX be an algebraicK3 surface. Fix an ample divisorH onX ,L ∈ Pic(X) and c2 ∈ Z. Let MH(r;L, c2) be the moduli space of rank r, H-stable vector bundles E over X with det(E) = L and c2(E) = c2. The goal of this paper is to determine invariants (r; c1, c2) for which MH(r;L, c2) is birational to some Hilbert scheme Hilb(X).

Microtext can be considered one form of micro-messaging which can include non-digital communications which have been digitized. We present our experiences and some results analyzing micro-messages in both military command and control (C2) and more general “C2-Lite” domains in order to predict other information such as the performance of a team, the topics of discussion, or the spread of ideas. ...

An approach to the generation of future adaptive mission-oriented command and control architectures is presented that uses “command and control capabilities” concept both for missions and C2 systems. The concept is modeled and formulated so that both missions and C2 systems can be normatively described by it: on the one hand, missions require the military has specific C2 capabilities and on the...

Let C1, C2 be Cantor sets embedded in the real line, and let τ1, τ2 be their respective thicknesses. If τ1τ2 > 1, then it is well known that the difference set C1 − C2 is a disjoint union of closed intervals. B. Williams showed that for some t ∈ int(C1−C2), it may be that C1∩ (C2 + t) is as small as a single point. However, the author previously showed that generically, the other extreme is tru...
