Abstract Background There is controversy regarding the efficacy of different treatment strategies for acute left malignant colonic obstruction. This study investigated 5-year overall survival (OS) and disease-free (DFS) several Methods We searched articles published in PubMed, Embase (Ovid), MEDLINE Web Science, Cochrane Library between January 1, 2000, July 2020. screened out literature compar...

BACKGROUND Systemic corticosteroids and inhaled beta(2) agonists are accepted first line treatments for acute severe asthma, but there is no consensus on their optimum dosage and frequency of administration. American regimens include higher initial dosages of beta(2) agonists and corticosteroids than UK regimens. METHODS In a prospective, pragmatic, randomised, parallel group study, 170 patie...

CICS Transaction Server 1.3 includes a significant set of new APIs under the umbrella title of CICS Business Transaction Services (CICS BTS). The aim of this set of APIs is to ease the development and deployment of complex, multi-transaction applications in the mainframe CICS environment. The APIs enable the explicit management of the collection of individual CICS transactions that implement an...

It is shown that explicit Bäcklund transformations (BTs) for the high-order constrained flows of soliton hierarchy can be constructed via their Darboux transformations and Lax representation, and these BTs are canonical transformations including Bäcklund parameter η and possess a spectrality property with respect to η and the ’conjugated’ variable μ for which the pair (η, μ) lies on the spectra...

The British Thoracic Society (BTS) guideline for the management of adults with community acquired pneumonia (CAP) published in 2009 was compared with the 2014 National Institute for Health and Care Excellence (NICE) Pneumonia Guideline. Of the 36 BTS recommendations that overlapped with NICE recommendations, no major differences were found in 31, including those covering key aspects of CAP mana...

Bäcklund transformations (BTs) for ordinary differential equations (ODEs), and in particular for hierarchies of ODEs, are a topic of great current interest. Here we give an improved method of constructing BTs for hierarchies of ODEs. This approach is then applied to fourth Painlevé (PIV ) hierarchies recently found by the same authors [Publ. Res. Inst. Math. Sci. (Kyoto) 37 327–347 (2001)]. We ...

In this paper, we study the hand-off performance of a wireless system with heterogeneous technologies called iCAR (Integrated Cellular and Ad hoc Relaying). In iCAR, hand-offs can occur not only from a Base Transceiver Station (BTS) to another BTS, but also from a BTS to a so-called Ad hoc Relaying Station (ARS) in the form of relaying, as well as from an ARS back to a BTS. The latter two types...

The base transceiver station (BTS)'s continuous power supply has been the subject of a lot research. majority research focuses on increasing usage effectiveness or adding solar battery systems for BTS stations. Due to geographical conditions in North Vietnam, cell efficiency is rather poor and investment cost quite high, therefore stations are still relying mostly generator backup systems. This...
