New 4-D Imaging for Real-Time Intraoperative MRI: Adaptive 4-D Scan [PDF]
, 2006 Aiming at real-time 3-D visualization of organ motion to navigate surgical procedures in MRI-guided surgery, a new 4-D MR imaging technique called "Adaptive 4-D Scan" has been proposed. The technique is designed to acquire a time series of volumetric 3-D images (4-D image) of cyclically moving organ, even in a low-field open-configuration MR scanner. A

3-D Shadows of 4-D Algebraic Hypersurfaces in a 4-D Perspective
, 2023 The paper is focused on the four-dimensional visualization of hypersurfaces represented by implicit equations without their parametrization. We describe a general method to find shadow boundaries in an arbitrary dimension and apply it in a three- and four-dimensional space.

Blowup for Biharmonic NLS [PDF]
, 2015 We consider the Cauchy problem for the biharmonic (i.\,e.~fourth-order) NLS with focusing nonlinearity given by $i \partial_t u = \Delta^2 u - \mu \Delta u -|u|^{2 \sigma} u$ for $(t,x) \in [0,T) \times \mathbb{R}^d$, where $0 < \sigma 4/d$, we prove a ...

TIME-SYMMETRIC INITIAL DATA SETS IN 4--D DILATON GRAVITY [PDF]
, 1995 I study the time--symmetric initial--data problem in theories with a massless scalar field (dilaton), free or coupled to a Maxwell field in the stringy way, finding different initial--data sets describing an arbitrary number of black holes with arbitrary

A Brane World Perspective on the Cosmological Constant and the Hierarchy Problems [PDF]
, 2001 We elaborate on the recently proposed static brane world scenario, where the effective 4-D cosmological constant is exponentially small when parallel 3-branes are far apart.

Risk Factors for Rehospitalizations after Allogeneic Hematopoietic Stem Cell Transplantation
Клиническая онкогематология, 2020 Aim. To assess the rehospitalization data of patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT), to determine possible risk factors for rehospitalization, and to work out a strategy of post-transplantation follow-up for this ...

P-term Potentials from 4-D Supergravity
, 2007 P-term inflation arises in some models of brane inflation. Within N=2 supersymmetry the scalar potential contains a vector of Fayet-Iliopoulos (FI) terms $\xi_i$. Depending on the direction of this vector it is possible to get D-term and F-term inflation

Finite-Size analysis of the 4-d abelian surface gauge model [PDF]
, 1994 We present the results of a finite-size analysis of the four dimensional abelian surface gauge model. This model is defined assigning abelian variables to the plaquettes of an hypercubical lattice, and is dual to the four dimensional Ising model.

4-d semistrict higher Chern-Simons theory I
, 2014 We formulate a 4-dimensional higher gauge theoretic Chern-Simons theory. Its symmetry is encoded in a semistrict Lie 2-algebra equipped with an invariant non singular bilinear form.
