Rarely, myelodysplastic syndrome (MDS) is complicated by an acquired form of α thalassemia (ATMDS) characterized by hypochromic, microcytic, anisopoikilocytic red cells with hemoglobin H (HbH) inclusions. Acquired mutations in ATRX, a chromatin remodelling gene, have recently been found in 12 patients with typical features of ATMDS, but have not been detected in MDS cases with similar red cell ...

This edition of the Journal starts with the big questions in psychiatry: what is a diagnosis? And how does one justify treatment against the will of the individual? The next version of the World Health Organization’s bible, the ICD–11, is being prepared at the same time as the American Psychiatric Association’s fifth edition of the DSM. The push for harmonising these two different systems is di...

Let G be an additive finite abelian group with exponent exp(G). Let S = g1 · . . . · gl be a sequence over G and k(S) = ord(g1)+· · ·+ord(gl) be its cross number. Let η(G) (resp. t(G)) be the smallest integer t such that every sequence of t elements (repetition allowed) from G contains a non-empty zero-sum subsequence T of length |T | ≤ exp(G) (resp. k(T ) ≤ 1). It is easy to see that t(G) ≥ η(...

Classification of blocks of subband samples according to their energy and variable bit allocation within the subsequent classes has demonstrated considerable gains in coding efficiency. The gains due to classification increase as smaller blocks are used; however, this increases the overheads for transmitting the classification information. In this paper, a quadtree based method is proposed. Thi...

The use of subband coding on image data is discussed. An overviev~ of siibbai~d coding is given. Advantages of subbanding for browsing and progressive resol~itiori ar-e presented. Implementations for lossless and lossy coding are discussed. Algorithn~ considerations and simple implementations of subband systems are given.

The present work aims to investigate the effect of individual rotational energy levels on fusion cross-sections for $^{16}$O-based reaction systems, namely, $^{16}$O + $^{182,184,186}$W, $^{176,180}${Hf}, $^{174,176}${Yb}, $^{166}${Er}, $^{148,152,154}$Sm, $^{150}$Nd at energies below barrier. Using CCFULL code, low-lying cross-section induced reactions has been investigated and around Coulomb ...

The Cover Feature shows that the N2 can be converted to NH3 on various defective MoS2 nanosheets. combined experimental data and DFT results demonstrate feasibility of sulfur-vacancy (VS-MoS2) for electrocatalytic ammonia synthesis. More information found in Aricle by B. Liu et al.
