The third generation spectroscopic study of Λ hypernuclei using (e,e'K+) reaction (JLab E05-115) was performed at JLab Hall-C in 2009. The experiment introduced the newly developed high-resolution ...electron spectrometer (HES) with the existing high-resolution kaon spectrometer (HKS). Experimental configuration, conditions, spectrometer designs and current status of analysis are presented.
A 24-year-old white man had a knife chest wound, and four months after this event, manifested progressive dyspnea. A false aneurysm of the left ventricle was diagnosed by 2D echocardiogram. Surgical ...resection of the aneurysmal sac with closure of the orifice of the lateral wall of the left ventricle was performed successfully.
Phys. Rev. C 103, 041301 (2021) Missing mass spectroscopy with the $(e,e^{\prime}K^{+})$ reaction was
performed at Jefferson Laboratory's Hall C for the neutron rich $\Lambda$
hypernucleus ...$^{9}_{\Lambda}{\rm Li}$. The ground state energy was obtained to
be $B_{\Lambda}^{\rm g.s.}=8.84\pm0.17^{\rm stat.}\pm0.15^{\rm sys.}~{\rm MeV}$
by using shell model calculations of a cross section ratio and an energy
separation of the spin doublet states ($3/2^{+}_1$ and $5/2^{+}_1$). In
addition, peaks that are considered to be states of $^{8}{\rm
Li}(3^{+})\otimes s_{\Lambda}=3/2^{+}_{2}, 1/2^{+}$ and $^{8}{\rm
Li}(1^{+})\otimes s_{\Lambda}=5/2^{+}_{2}, 7/2^{+}$ were observed at
$E_{\Lambda}({\rm no.~2})=1.74\pm0.27^{\rm stat.}\pm0.11^{\rm sys.}~{\rm MeV}$
and $E_{\Lambda}({\rm no.~3})=3.30\pm0.24^{\rm stat.}\pm0.11^{\rm sys.}~{\rm
MeV}$, respectively. The $E_{\Lambda}({\rm no.~3})$ is larger than shell model
predictions by a few hundred keV, and the difference would indicate that a
${\rm ^{5}He}+t$ structure is more developed for the $3^{+}$ state than those
for the $2^{+}$ and $1^{+}$ states in a core nucleus $^{8}{\rm Li}$ as a
cluster model calculation suggests.
Myocardial infarction secondary to nonpenetrating chest trauma is rare. We present the case of a sportsman who developed an acute transmural posteroinferior wall myocardial infarction due to chest ...trauma by a football. The angiographic study revealed total obstruction of the proximal right coronary artery.
We present a case of an anomalous origin of the left coronary artery arising from the pulmonary artery in a 60 year old woman with ventricular arrhythmias and ischemic electrocardiographic changes ...but who had tolerated eleven normal pregnancies and deliveries without complications. No cardiac surgical repair has been performed and she is asymptomatic and has been well controlled with diisopyramide during a ten year follow up.
A sixty-two-year-old white woman with a 14.5 cm (145 mm) silent giant left atrial enlargement secondary probably to rheumatic heart disease is presented. Aside from mild progressive shortness of ...breath during the past year, the patient had been asymptomatic all her life. Her clinical picture was manifested for the first time by syncope secondary to slow atrial fibrillation, for which a permanent pacemaker was required. The correct diagnosis of the enlarged chamber was not possible through the routine chest roentgenogram. In this case, the echocardiogram, nuclear angiogram, and computed tomography were the pertinent studies needed to reach the diagnosis.
