The hydroboration of phosphaalkynes with Piers' borane (HB(C6 F5 )2 ) generated unusual phosphaalkenylboranes [RCH=PB(C6 F5 )2 ]2 that persisted as dimers in both solution and the solid state. These P2 B2 heterocycles underwent ring opening when subjected to nucleophiles, such as pyridine and tert-butylisocyanide, to yield monomeric phosphaalkenylborane adducts RCH=PB(C6 F5 )2 (L). DFT calculat...
Front Cover In article number 2201409, Daqing Sun, Dan Ding, and co-workers propose a fluorinated supramolecular strategy for developing cancer vaccine adjuvant, of which 4RDP(F5) containing tetra-arginine (4R) dipentafluorophenylalanine (DP(F5)) balances the self-assembly, antigen affinity, transmembrane abilities. The performance 4RDP(F5)-OVA in prevention treatment tumors makes it an attract...
Many steganographic systems are weak against visual and statistical attacks. Systems without these weaknesses offer only a relatively small capacity for steganographic messages. The newly developed algorithm F5 withstands visual and statistical attacks, yet it still offers a large steganographic capacity. F5 implements matrix encoding to improve the efficiency of embedding. Thus it reduces the ...
Area F5, in the ventral premotor cortex of the macaque monkey, plays a critical role in determining the hand shape appropriate for grasp of a visible object. F5 neurones show increased firing for particular types of grasp, and inactivation of F5 produces deficits in visually guided grasp. But how is F5 activity transformed into the appropriate pattern of hand muscle activity for efficient grasp...
30 The responses of individual primate corticospinal neurons to localized electrical stimulation 31 of primary motor (M1) and of ventral premotor cortex (area F5) are poorly documented. To 32 rectify this and to study interactions between responses from these areas, we recorded 33 corticospinal axons, identified by pyramidal tract stimulation, in the cervical spinal cord of 34 three chloralose-...
حل دستگاه های چندجمله ای چندمتغیره توسط پایه گروبنر، از قسمت های اساسی جبر محاسباتی است که توسط بوخ برگر در سال 1965 با ارائه در تز دکترایش وارد عرصه علمی شد. طی چند سال اخیر الگوریتم های مختلفی برای محاسبه ی پایه گروبنر ارائه شد که یکی از قویترین و کاراترین الگوریتم های موجود، الگوریتم f5 است. این الگوریتم با داشتن محک های قوی، از محاسبات غیر ضروری (با حذف زوج های غیر مفید) جلوگیری می ک...
Herein, we extend our "combined electrochemical-frustrated Lewis pair" approach to include Pt electrode surfaces for the first time. We found that the voltammetric response of an electrochemical-frustrated Lewis pair (FLP) system involving the B(C6 F5 )3 /[HB(C6 F5 )3 ]- redox couple exhibits a strong surface electrocatalytic effect at Pt electrodes. Using a combination of kinetic competition s...
This paper develops a model for research and practice of strategic management of information technology. The model, termed the Strategic Alignment Model, is defined in terms of four domains of strategic choice: business strategy; information technology strategy; organization infrastructure and processes; and information technology infrastructure and processes -each with its constituent dimensio...
Adoptive cell transfer (ACT) of ex vivo engineered autologous lymphocytes encoding high-affinity MART-1/HLA-A 0201–specific T-cell receptor (TCR)a/b chains (F5 CTL), densely infiltrate into sites of metastatic disease, mediating dramatic but partial clinical responses in patients with melanoma. We hypothesized that MART-1 downmodulation in addition to aberrant apoptotic/survival signaling could...
