A Case of Haemorrhages caused by Multiple Myeloma Induced Factor Deficiencies: A Bleeding Enigma [PDF]
Journal of Clinical and Diagnostic ResearchA 74-year-old male patient presented with anaemia, thrombocytopenia, and extensive haemorrhages over both thighs and back. A coagulation work-up revealed markedly elevated Prothrombin Time (PT) and activated Partial Thromboplastin Time (aPTT).

Real Polynomial Gram Matrices Without Real Spectral Factors [PDF]
arXiv, 2019 It is well known that a non-negative definite polynomial matrix (a polynomial Gramian) $G(t)$ can be written as a product of its polynomial spectral factors, $G(t) = X(t)^H X(t)$. In this paper, we give a new algebraic characterization of spectral factors when $G(t)$ is real-valued. The key idea is to construct a representation set that is in bijection

The Journal of Haemophilia Practice, 2023 Haemophilia A and B are X-linked inherited bleeding disorders, resulting in the deficiency of clotting factor VIII and IX, respectively. Since the introduction of recombinant clotting factor concentrates in the early 1990s, the major safety concern for ...

Hereditary Factor X (Stuart-Prower Factor) Deficiency [PDF]
Medical Journal Armed Forces India, 2008 Inherited deficiency of Factor X was first reported way back in mid 1950s by workers who were studying patients with a haemorrhagic disease resembling factor VII deficiency. It is also known by the surnames of the patients who were first found to manifest the defect (Stuart and Prower).

An Alternative Proof of the $H$-Factor Theorem [PDF]
arXiv, 2011 Let $H: V(G) \rightarrow 2^{\mathbb{N}}$ be a set mapping for a graph $G$. Given a spanning subgraph $F$ of $G$, $F$ is called a {\it general factor} or an $H$-{\it factor} of $G$ if $d_{F}(x)\in H(x)$ for every vertex $x\in V(G)$. $H$-factor problems are, in general, $NP$-complete problems and imply many well-known factor problems (e.g., perfect ...

Concerning Order and Disorder in the Ensemble of Cu-O Chain Fragments in Oxygen Deficient Planes of Y-Ba-Cu-O [PDF]
, 1994 In connection with numerous X-ray and neutron investigations of some high temperature superconductors (YBa$_2$Cu$_3$O$_{6+x}$ and related compounds) a non-trivial part of the structure factor, coming from partly disordered Cu-O-$\dots$-O-Cu chain fragments, situated within basal planes, CuO$_x$, can be a subject of theoretical interest.

Perinatal Gene Transfer to the Liver [PDF]
, 2011 The liver acts as a host to many functions hence raising the possibility that any one may be compromised by a single gene defect. Inherited or de novo mutations in these genes may result in relatively mild diseases or be so devastating that death within

On Deficient Perfect Numbers with Four Distinct Prime Factors [PDF]
, 2019 For a positive integer $n$, if $\sigma(n)$ denotes the sum of the positive divisors of $n$, then $n$ is called a deficient perfect number if $\sigma(n)=2n-d$ for some positive divisor $d$ of $n$. In this paper, we prove some results about odd deficient perfect numbers with four distinct prime factors.
