A Sterile Neutrino Search with Kaon Decay-at-rest

Monoenergetic muon neutrinos (235.5 MeV) from positive kaon decay-at-rest are considered as a source for an electron neutrino appearance search. In combination with a liquid argon time projection chamber based detector, such a source could provide discovery-level sensitivity to the neutrino oscillation parameter space indicative of a sterile neutrino. Current and future intense >3 GeV kinetic energy proton facilities around the world can be employed for this experimental concept.Comment: 6 pages, 6 figure

Final State Interactions Effects in Neutrino-Nucleus Interactions

Final State Interactions effects are discussed in the context of Monte Carlo simulations of neutrino-nucleus interactions. A role of Formation Time is explained and several models describing this effect are compared. Various observables which are sensitive to FSI effects are reviewed including pion-nucleus interaction and hadron yields in backward hemisphere. NuWro Monte Carlo neutrino event generator is described and its ability to understand neutral current $\pi^0$ production data in $\sim 1$ GeV neutrino flux experiments is demonstrated.Comment: 13 pages, 16 figure

Classification of Low Dimensional Lie Super-Bialgebras

A thorough analysis of Lie super-bialgebra structures on Lie super-algebras osp(1|2) and super-e(2) is presented. Combined technique of computer algebraic computations and a subsequent identification of equivalent structures is applied. In all the cases Poisson-Lie brackets on supergroups are found. Possibility of quantizing them in order to obtain quantum groups is discussed. It turns out to be straightforward for all but one structures for super-E(2) group.Comment: 15 pages, LaTe

Coeliac trunk and its anatomic variations: a cadaveric study

Background: Coeliac trunk (CT) is the first major visceral branch of the abdominal aorta. The aim of this work was to present the CT division pattern and its anatomical variants in a sample of Polish population. Materials and methods: Coeliac trunk dissection was performed in 50 adult cadavers in the Department of Anatomy, Jagiellonian University Medical College. Cadavers of Polish subjects were included. Cadavers with previous upper abdominal surgery, abdominal trauma, disease process that distorted arterial anatomy or signs of putrefaction were excluded. CT variations, accessory vessels, and vertebral level of origin were described. CT patterns were reported according to the Adachi classification. This study was reviewed and approved by the local Ethics Committee. Results: Coeliac trunk consisting of the left gastric, common hepatic and splenic artery (type 1 according to the Adachi classification) was found in 82% of cadavers. The true tripod was found in 20% and the false one in 80%. Additional vessels were also found: greater pancreatic from the splenic artery and left inferior phrenic from the left gastric artery, which accounted for 2% sections. Type 2 according to the Adachi classification (i.e. the hepatosplenic trunk) was found in 16% of the sections. Other types of CT were not observed. The level of origin was found to be at the inter-vertebral disc between T12 and L1 in all of the cases. Conclusions: Based on the analysis of the sectional material of the Department of Anatomy, it was found that the typical visceral segmental division is approximate to that observed by Adachi in its classification, whereas the second type of CT was twice as frequent and no other, less frequent types were found

Rare combined variations of the coeliac trunk, accessory hepatic and gastric arteries with co-occurrence of double cystic arteries

Many variations of the coeliac trunk and hepatic or gallbladder arterial supply have been reported before in many cadaveric and radiologic studies. In this case we present combined anomalies observed in dissected cadaver of a 73-year-old female. The left gastric artery arises directly from the abdominal aorta and gives two branches: the right inferior phrenic artery in the proximal part and the accessory left hepatic artery in the distal part. The coeliac trunk is bifurcated into the common hepatic artery and the splenic artery. The right gastric artery emerges from the left hepatic artery. The right hepatic artery gives two cystic arteries and the accessory right hepatic artery is noticed arising from the posterior superior pancreaticoduodenal artery. The deep cystic artery and the right inferior phrenic artery give hepatic branches. Also, we noticed small accessory biliary duct going to the cystic duct. This complexity of the arterial supply with anomaly of the biliary ducts has many surgical implications which will be herein discussed

Unusual variations in the branching pattern of the coeliac trunk and their clinical significance

Background: The anatomical variations of the coeliac trunk are due to developmental changes in the ventral segmental arteries. Multidetector computed tomography (MDCT) has been used to investigate vascular anatomy for scientific and diagnostic purposes. These studies allow for much larger sample sizes than traditional cadaveric studies. The aim of this research was to isolate rare anatomical variants of the coeliac trunk and emphasize their clinical significance. Materials and methods: A descriptive, retrospective study was carried out on MDCT angiographies performed from January 2020 till March 2020 in Polish patients. Coeliac trunk was studied and normal and anatomical variations were identified. Results: Out of total 350 patients, hepatogastrosplenic trunk was predominant. However, we observed: coeliaco-mesenteric and hepatogastric trunk type, hepatic artery variations and coeliac axis stenosis with collateral mesenteric circulation. Conclusions: Rare variations of the coeliac trunk should always be anticipated before radiological and surgical interventions. Knowledge of unusual coeliac trunk anatomy is important in hepatopancreatobiliary surgery, transplantology, and interventional radiology

Transverse Enhancement Model and MiniBooNE Charge Current Quasi-Elastic Neutrino Scattering Data

Recently proposed Transverse Enhancement Model of nuclear effects in Charge Current Quasi-Elastic neutrino scattering [A. Bodek, H. S. Budd, and M. E. Christy, Eur. Phys. J. C{\bf 71} (2011) 1726] is confronted with the MiniBooNE high statistics experimental data. It is shown that the {\it effective} large axial mass model leads to better agreement with the data.Comment: 4 pages, 6 figure

Anatomical variants of coeliac trunk in Polish population using multidetector computed tomography angiography

Background: Multidetector computed tomography angiography (MDCTA) has become a major part in evaluation of normal anatomy and its variants in patients undergoing operative or interventional procedures. The purpose of this study was to assess the frequency of anatomical variation of coeliac trunk in patients undergoing MDCTA of the abdominal aorta. Materials and methods: A descriptive, retrospective study was carried out on MDCTAs performed from January 2014 till January 2020 in Polish patients. Coeliac trunk was studied and normal and anatomical variations were noted according to Adachi’s classification. All patients with abnormalities affecting the vessels or a history of any vascular abnormality were excluded from the study. Results: Out of total 1000 patients, hepatogastrosplenic trunk was found in 93.0%. True and false types of trifurcation were observed. Hepatosplenic trunk was found in 2.8%, coeliacomesenteric trunk in 1.1%, hepatomesenteric trunk in 1.7% gastrosplenic trunk was found in 1.4%. We have not observed hepatosplenomesenteric trunk. Conclusions: The type and knowledge of anatomy is of prime importance for an optimum preoperative planning in surgical or radiological procedure. MDCTA allows minimally invasive assessment of arterial anatomy with high quality three-dimensional reconstruction images

Wroclaw neutrino event generator

A neutrino event generator developed by the Wroclaw Neutrino Group is described. The physical models included in the generator are discussed and illustrated with the results of simulations. The considered processes are quasi-elastic scattering and pion production modelled by combining the $\Delta$ resonance excitation and deep inelastic scattering.Comment: Talk given at 2nd Scandanavian Neutrino Workshop (SNOW 2006), Stockholm, Sweden, 2-6 May 2006. 3 pages, 6 figure
