Fast load transient response and high light-load efficiency are two key features of the constant on-time (COT) control technique that has been widely used in numerous applications, such as for voltage regulators point-of-load converters. However, when step-down occurs during an interval, COT controller cannot respond until interval expires. This delay causes additional output overshoot, resulti...

Solvation of [(CNT)Ln(η8-COT)] (Ln=La, Ce, Nd, Tb, Er; CNT=cyclononatetraenyl, i.e., C9H9−; COT=cyclooctatetraendiid, C8H82−) complexes with tetrahydrofuran (THF) gives rise to neutral [(η4-CNT)Ln(thf)2(η8-COT)] Ce) and ionic [Ln(thf)x(η8-COT)][CNT] (x=4 (Ce, Tb), 3 (Er)) species in a solid-to-solid transformation. Due the severe distortion ligand sphere upon solvation, these act as switchable ...

Abstract. The representation of aerosol–cloud interaction (ACI) and its impacts in the current climate or weather model remains a challenge, especially for severely polluted regions with high aerosol concentration, which is even more important worthy study. Here, ACI first implemented atmospheric chemistry GRAPES_Meso5.1/CUACE by allowing real-time activation Thompson cloud microphysics scheme....

For simplicity, we adopt the following convention: x, r, s, h denote real numbers, n denotes an element of N, Z denotes an open subset of R, and f , f1, f2 denote partial functions from R to R. The following propositions are true: (1) ]−π2 , π 2 [ ⊆ dom (the function tan). (2) ]0, π[ ⊆ dom (the function cot). (3)(i) The function tan is differentiable on ]−π2 , π 2 [, and (ii) for every x such t...

We consider the problem of securely computing the Greater Than (GT) predicate and its generalization – securely determining membership in a union of intervals. We approach these problems from the point of view of Q-Conditional Oblivious Transfer (Q-COT), introduced by Di Crescenzo, Ostrovsky and Rajagopalan [4]. Q-COT is an oblivious transfer that occurs iff predicate Q evaluates to true on the...

The title compound, [Sm(C(25)H(35)N(2))(C(14)H(24)Si(2))(C(4)H(8)O)]·C(7)H(8), was prepared by treatment of anhydrous samarium trichloride with a 1:1 mixture of in situ-prepared Li(DippForm) [DippFormH = N,N'-bis-(2,6-diisopropyl-phen-yl)methanimidamide] and Li(2)(COT'') [COT'' = 1,4-bis-(trimethyl-sil-yl)cyclo-octa-tetra-enyl] in tetra-hydro-furan (THF). Despite the presence of two very bulky ...

BACKGROUND Acute respiratory failure (ARF) is a common and life-threatening medical emergency in patients admitted to the hospital. Currently, there is a lack of large-scale evidence on the use of high-flow nasal cannulas (HFNC) in patients with ARF. In this systematic review and meta-analysis, we evaluated whether there were differences between HFNC therapy and conventional oxygen therapy (COT...

This paper presents an investigation of the expected uncertainties of a single channel cloud optical thickness (COT) retrieval technique, as well as a simple cloud temperature threshold based thermodynamic phase approach, in support of the Deep Space Climate Observatory (DSCOVR) mission. DSCOVR cloud products will be derived from Earth Polychromatic Imaging Camera (EPIC) observations in the ult...

BACKGROUND High-flow nasal cannula oxygen (HFNC) is a relatively new therapy used in adults with respiratory failure. Whether it is superior to conventional oxygen therapy (COT) or to noninvasive mechanical ventilation (NIV) remains unclear. The aim of the present study was to investigate whether HFNC was superior to either COT or NIV in adult acute respiratory failure patients. METHODS A rev...

This paper presents the design of two separate continually online trained (COT) neurocontrollers for excitation and turbine control of a turbogenerator connected to the infinite bus through a transmission line. These neurocontrollers augment/replace the conventional automatic voltage regulator and the turbine governor of a generator. A third COT artificial neural network is used to identify the...
