N,N,N-Trimethyl-N-(methyl 5-deoxy-2,3-O-isopropylidene-β-d-ribofuranosid-5-yl)ammonium 4-methylbenzenesulfonate sesquihydrate

open access: yesActa Crystallographica Section E, 2013
The structure of the title compound, [C12H24NO4][C7H7O3S]·1.5H2O, contains alternating layers parallel to (001) of hydrophobic and polar character, stabilized by C—H...O hydrogen bonding. The furan ring adopts an envelope conformation with the

N $$ \mathcal{N} $$ -extended D = 4 supergravity, unconventional SUSY and graphene

open access: yesJournal of High Energy Physics, 2020
We derive a 2+1 dimensional model with unconventional supersymmetry at the boundary of an AdS4 N $$ \mathcal{N} $$ -extended supergravity, generalizing previous results. The (unconventional) extended supersymmetry of the boundary model is instrumental in

(n,p), (n,2n), (n,d), and (n,α) cross-section calculations of 16O with 0-40 MeV energy neutrons

open access: yesEPJ Web of Conferences, 2015
Oxygen is one of the elements which interacts with emitted neutrons after fission reactions. Oxygen exists abundantly both in nuclear fuel (UO2) and moderators (H2O).

On α′-effects from D-branes in 4d N $$ \mathcal{N} $$ = 1

open access: yesJournal of High Energy Physics, 2020
In this work we study type IIB Calabi-Yau orientifold compactifications in the presence of space-time filling D7-branes and O7-planes. In particular, we conclude that α′2 g s -corrections to their DBI actions lead to a modification of the four ...

SÍNTESE DE N-GLICOSILSULFONAMIDAS DERIVADAS DE D-GLICOSE E N-ACETILGLICOSAMINA

open access: yesQuímica Nova, 2015
Herein, we report the synthesis of β-N-glycosylsulfonamides derivatives of D-glucose and N-acetylglucosamine using conventional methods. We also describe a procedure that allows the preparation of these compounds in good yields without the anomerization ...

$$\theta $$ θ -diagram technique for $${\mathcal {N}}=1$$ N = 1 , $$d=4$$ d = 4 superfields

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We describe a diagrammatic procedure to carry out the Grassmann integration in super-Feynman diagrams of 4d theories expressed in terms of $${\mathcal {N}}=1$$ N = 1 superfields. This method is alternative to the well known D-algebra approach. We develop

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

Survival Outcomes and Complications Among Canadian Children With Retinoblastoma: A Population‐Based Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.

Deformation of d = 4, N $$ \mathcal{N} $$ ≥ 5 supergravities breaks nonlinear local supersymmetry

open access: yesJournal of High Energy Physics, 2023
We study d = 4, N $$ \mathcal{N} $$ ≥ 5 supergravities and their deformation via candidate counterterms, with the purpose to absorb UV divergences. We generalize the earlier studies of deformation and twisted self-duality constraint to the case with ...
