Review of Particle Physics

Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

The Pythia program can be used to generate high-energy-physics ''events'', i.e. sets of outgoing particles produced in the interactions between two incoming particles. The objective is to provide as accurate as possible a representation of event properties in a wide range of reactions, within and beyond the Standard Model, with emphasis on those where strong interactions play a role, directly or indirectly, and therefore multihadronic final states are produced. The physics is then not understood well enough to give an exact description; instead the program has to be based on a combination of analytical results and various QCD-based models. This physics input is summarized here, for areas such as hard subprocesses, initial- and final-state parton showers, underlying events and beam remnants, fragmentation and decays, and much more. Furthermore, extensive information is provided on all program elements: subroutines and functions, switches and parameters, and particle and process data. This should allow the user to tailor the generation task to the topics of interest.

Purpose: Chronic kidney disease (CKD) is a major health problem and is closely linked with cardiovascular disease. Pulmonary hypertension (PH) is considered a common comorbidity in CKD patients. This study aimed at assessing the correlation between CKD and pulmonary hypertension. 
Methodology: This is a retrospective study that recruited 100 Egyptian patients with stage 3 and above Chronic Kidney Disease (CKD) (KDOQI    guidelines). The study sample was composed of 100 patients with 60% overall prevalence of PH. Transthoracic echo Doppler study was performed to measure pulmonary artery systolic pressure based on tricuspid jet in the sample. 
Findings: There was significant association between PH and severity of renal disease. The hemodialysed group showed a higher prevalence of PH with a more severe PH compared to groups not on regular dialysis. The study had provided evidence that PH is a common comorbidity in CKD patients and is directly proportional with the stage and duration of CKD. 
Recommendations: Pulmonary hypertension should be regularly assessed using echocardiography in CKD patients specially those on regular dialysis.

We introduce the largest transcribed Arabic speech corpus, QASR, collected from the broadcast domain. This multi-dialect speech dataset contains 2,000 hours of speech sampled at 16kHz crawled from Aljazeera news channel. The dataset is released with lightly supervised transcriptions, aligned with the audio segments. Unlike previous datasets, QASR contains linguistically motivated segmentation, punctuation, speaker information among others. QASR is suitable for training and evaluating speech recognition systems, acoustics- and/or linguistics- based Arabic dialect identification, punctuation restoration, speaker identification, speaker linking, and potentially other NLP modules for spoken data. In addition to QASR transcription, we release a dataset of 130M words to aid in designing and training a better language model. We show that end-to-end automatic speech recognition trained on QASR reports a competitive word error rate compared to the previous MGB-2 corpus. We report baseline results for downstream natural language processing tasks such as named entity recognition using speech transcript. We also report the first baseline for Arabic punctuation restoration. We make the corpus available for the research community.

We compute the decay rates for the exclusive decays B ± → ( η ′ , η )( K ± , K ∗± ) and B 0 → ( η ′ , η )( K 0 , K ∗ 0 ) in a QCD-improved factorization framework by including the contribution from the process b → sgg → s ( η ′ , η ) through the QCD anomaly. This method provides an alter-native estimate of the contribution b → sc ¯ c → s ( η, η ′ ) to these decays as compared to the one using the intrinsic charm content of the η ′ and η mesons determined through the decays J/ψ → ( η, η ′ , η c ) γ . The advantage of computing the relevant matrix elements via the QCD anomaly governing the transition gg → ( η ′ , η ) is that there is no sign ambiguity in these contributions relative to the matrix elements from the rest of the operators in the weak eﬀective Hamiltonian. Numerically, the QCD anomaly method and the one using the radiative decays J/ψ → ( η, η ′ , η c ) γ give similar branching ratios for the decays of interest here. The resulting branching ratios are compared with the CLEO data on B ± → η ′ K ± and B 0 → η ′ K 0 and predictions are
