Aggregation induced emission (AIE) active and acid/base controllable amphiphilic [2]rotaxanes R1 and R2 were successfully constructed with tetraphenylethene (TPE) as a stopper and t-butylcalix[4]arene or calix[4]arene macrocycle as a wheel over the axle component. The AIE effect of [2]rotaxanes R1 and R2 was greatly affected by the molecular shuttling of t-butylcalix[4]arene or calix[4]arene macrocycle, which was triggered by the acid/base strategy. In the case of [2]rotaxane R1, aggregation was achieved in the presence of less amount of water compared with those of [2]rotaxane R2, and the deprotonated [2]rotaxanes R1-b and R2-b, owing to the stronger interaction between the TPE and t-butylcalix[4]arene macrocycle and restricted intramolecular rotation (RIR), thus making it responses in less quantity of water along with highly fluorescent emission. [2]Rotaxane R1-b started to aggregate at 70% water fraction (f(w)), while [2]rotaxane R2-b started to aggregate at 75% f(w) which allowed them to morph into hollow nanospheres, whereas they formed only nanospheres at 99% f(w) in CH3CN/water cosolvent system due to the higher degree of aggregation in aqueous media. To our delight, controllable morphology of self-assembled structures was indeed formed from these [2]rotaxanes. Interestingly, by the interplay of a wide range of multi-self-assembly driving forces, the slack stacking of rotaxane unit forms a hollow on the surface of nanospheres to become hollow nanospheres. Among the four [2]rotaxanes studied here, R1 possessed a narrower HOMO-LUMO band gap compared to those others, as confirmed by computational study. Furthermore, only [2]rotaxane R1 formed organogel in methanol solvent and its reversible gel-sol transition could be achieved by the addition of acid and base. This implies that the formation of dumbbell shape cross-linked 3D network structures were mainly governed by pi-pi stacking, van der Waals force, and intermolecular H-bonding interactions during the gelation processes.

The follicle-stimulating hormone (FSH) is a hormone that belongs to a family of glycoprotein hormones. Determination of FSH can help in interpreting various factors that include physiology of the reproductive system, fertility maintenance, and identification or treatment of reproductive disorders. Sialic acids are derivatives of neuraminic acids with negative charges, present at the end of the sugar chains and further linked to the cell surfaces and glycoproteins. The direct measurement of FSH in a human body can be recorded by developing a sensor probe that responds particularly to sialic acids over the other hormones. However, existing diagnostic methods still suffer from many difficulties in terms of complicated handling techniques, expensive instrumentation, etc. Development of accurate, rapid, and low-cost FSH detection chemosensors is important to meet these demands. Herein, we utilized a novel sensing method for accurate and fast FSH detection using a metal-oxide semiconductor silicon nanowire field effect transistor (SiNW-FET) device. This is the first report to demonstrate the boronic acid-functionalized SiNW-FET device in FSH detection. FSH detection has been successfully determined using an assay buffer solution with 0.72 fM detection limit as well as using 20% serum with 1.1. fM detection limit. We also investigated the specificity with other gonadotropins/glycosylated serum proteins. The current measurements on FSH concentrations at different time intervals were also studied. The sensitive, cheap, and miniaturized SiNW-FET device can serve as an effective sensing approach for rapid screening of FSH and menopause diagnosis.

A method and a system are disclosed for simulating a network topology using a physical machine. A physical switch with multiple ports is divided into multiple slice switches according to a network topology. Each slice switch simulates a node in a network. Every virtual port of the slice switch corresponds to a physical port. In simulation operation, a port-mapping table is applied to allow the virtual port to be one-to-one mapped to one physical port; a VLAN conversion table is used to manage the VLAN IDs for the virtual ports and to configure a VLAN tag applied to a simulated packet so that the packet can operate in the slice switch; an output port table is used to determine the output port of the simulated packet; and a pop-off VLAN tag table is used to allow the packet to restore to its original VLAN ID or non-VLAN tag state.

MHC class I chain-related gene A (MICA) variants have been associated with hepatocellular carcinoma (HCC). Their association with MICA expression in cancer cells and cancer recurrence is unknown. SNP rs2596542 of MICA was tested in 193 HCC patients with surgical resection. The corresponding MICA expression in the cancer tissue was measured by immunochemistry microarray. Patients with the SNP rs2596542 A allele had significantly lower MICA expression in tumor tissue than did those with the GG genotype (24.7 +/- 15.1% vs. 41.5 +/- 23.4%, P < 0.001). Patients who had HCC recurrence had significantly lower MICA expression in tumor tissue (34.2 +/- 21.8% vs. 24.0 +/- 19.8%, P = 0.03). Cox regression analysis revealed that the factors independently predictive of HCC recurrence included low MICA expression (hazard ratio [HR]/95% confidence intervals [CI]: 2.77/1.07-7.14, P = 0.035) and tumor size (HR/CI: 5.22/2.11-12.96, P < 0.001). Compared to patients with tumors <5 cm and MICA expression >30%, patients with either one and both two risk factors had HCC HRs of 9.76 (C.I. 1.27-75.03, P = 0.03) and 27.30 (C.I. 3.46-215.6, P = 0.002), respectively. We concluded that low cellular MICA expressions were at a greater risk of HCC recurrence after curative treatment.
On the Electrical Characteristics of Ferroelectric FinFET Using Hafnium Zirconium Oxide with Optimized Gate Stack

We investigated a short-channel ferroelectric FinFET using a ferroelectric HfZrO thin film as gate dielectrics, and scaled down the channel length to 60 nm to study the short-channel effect and the ferroelectricity. The HfZrO FinFETs exhibited improved short-channel performance including subthreshold swing improvement and reduced drain-induced barrier lowering effect. By using pulsed I-V measurement method, we confirmed that the thickness tradeoff between HfZrO ferroelectric layer and buffered layer are critical to alleviate the influence of interface traps and simultaneously obtain the ferroelectricity in HfZrO FinFET devices with the consideration of sidewall traps. Interface traps may cause unwanted off-state leakage current and mismatching negative capacitance. Here, we demonstrated that the ferroelectric behavior can be achieved by simultaneously increasing HfZrO thickness to obtain the optimized polarization and adopt appropriate buffered layer to screen the traps effect under ferroelectric domain switching.

We report the observation of a rotationally resolved (6) band associated with the OO-stretching mode of the simplest Criegee intermediate, CH2OO, in the range of 879.5-932.0 cm(-1) (11.37-10.73 m) at an optical resolution of 0.0015 cm(-1). The spectra were recorded with a tunable cw external-cavity quantum-cascade laser (EC-QCL) system coupled with a Herriott multipass absorption cell. Over one thousand lines were assigned to determine the rovibrational parameters of the (6) band. Rotational parameters A, B, and C and higher-order parameters (J), (JK), (K), (J), and (K) were determined precisely. Rotational perturbations for K-a = 3, K-a = 6, and K-a 11 on high-J levels were observed. In particular, for K-a = 6, frequency shifts as a function of J showed an avoided crossing; the shifts were analyzed in terms of a Coriolis interaction between modes (6) and (8) of CH2OO. According to the distinct temporal profiles, lines of a hot band near 899.5 cm(-1) were also identified.
