A Single-Layer Compact HF-UHF Dual-Band RFID Tag Antenna (2012)

This letter presents a novel dual-band (HF and UHF) radio frequency identification (RFID) tag antenna. Two key challenges are faced: the compact dimension and the impaired bandwidth due to the couplings between two band structures. To enable the implementation of whole design on a credit-card-size single-layer support, a spiral coil along the edges of the card is designed to handle the HF (13.56 MHz) near-field coupling, and the UHF antenna is placed inside the coil instead of outside. Meanwhile, a diagonal symmetric design consisting of two meander lines inside the spiral coil is adopted for UHF band. This structure supports multiple resonance modes around 915 MHz to broaden the working bandwidth under the large inductive circumstance from the HF coil. The proposed antenna is easy for adjustment with ways of handling both coarse tuning and fine-tuning. Its overall dimension is of a credit card size on a single-layer thin substrate. The design methodology and antenna measurement results are both presented and discussed in the letter.
Investigation of the Protective Effects of Phlorizin on Diabetic Cardiomyopathy indb/dbMice by Quantitative Proteomics (2013)

Patients with diabetes often develop hypertension and atherosclerosis leading to cardiovascular disease. However, some diabetic patients develop heart failure without hypertension and coronary artery disease, a process termed diabetic cardiomyopathy. Phlorizin has been reported to be effective as an antioxidant in treating diabetes mellitus, but little is known about its cardioprotective effects on diabetic cardiomyopathy. In this study, we investigated the role of phlorizin in preventing diabetic cardiomyopathy in db/db mice. We found that phlorizin significantly decreased body weight gain and the levels of serum fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), and advanced glycation end products (AGEs). Morphologic observations showed that normal myocardial structure was better preserved after phlorizin treatment. Using isobaric tag for relative and absolute quantitation (iTRAQ) proteomics, we identified differentially expressed proteins involved in cardiac lipid metabolism, mitochondrial function, and cardiomyopathy, suggesting that phlorizin may prevent the development of diabetic cardiomyopathy by regulating the expression of key proteins in these processes. We used ingenuity pathway analysis (IPA) to generate an interaction network to map the pathways containing these proteins. Our findings provide important information about the mechanism of diabetic cardiomyopathy and also suggest that phlorizin may be a novel therapeutic approach for the treatment of diabetic cardiomyopathy.

Characterization of rockfalls from seismic signal: Insights from laboratory experiments (2015)

Abstract The seismic signals generated by rockfalls can provide information on their dynamics and location. However, the lack of field observations makes it difficult to establish clear relationships between the characteristics of the signal and the source. In this study, scaling laws are derived from analytical impact models to relate the mass and the speed of an individual impactor to the radiated elastic energy and the frequency content of the emitted seismic signal. It appears that the radiated elastic energy and frequencies decrease when the impact is viscoelastic or elastoplastic compared to the case of an elastic impact. The scaling laws are validated with laboratory experiments of impacts of beads and gravels on smooth thin plates and rough thick blocks. Regardless of the involved materials, the masses and speeds of the impactors are retrieved from seismic measurements within a factor of 3. A quantitative energy budget of the impacts is established. On smooth thin plates, the lost energy is either radiated in elastic waves or dissipated in viscoelasticity when the impactor is large or small with respect to the plate thickness, respectively. In contrast, on rough thick blocks, the elastic energy radiation represents less than 5% of the lost energy. Most of the energy is lost in plastic deformation or rotation modes of the bead owing to surface roughness. Finally, we estimate the elastic energy radiated during field scale rockfalls experiments. This energy is shown to be proportional to the boulder mass, in agreement with the theoretical scaling laws.
Distribution of Methicillin-Resistant Staphylococcus aureus Clones Among Health Care Facilities in Connecticut, New Jersey, and Pennsylvania (2000)

A previous surveillance study conducted in 12 hospitals in New York City in 1996 identified a unique multidrug-resistant genetic lineage of methicillin-resistant Staphylococcus aureus (MRSA) that was widespread and accounted for as much as 42% of all the MRSA isolates. The purpose of the study described here was to determine possible geographic spread of this New York clone of MRSA to neighboring states. Single-patient MRSA isolates (258) from 29 health care facilities in Connecticut (CT), New Jersey (NJ), and Pennsylvania (PA) were collected during the calendar year 1998. DNA typing, consisting of fingerprinting of chromosomal macrorestriction patterns generated by SmaI digestion followed by pulsed-field gel electrophoresis (PFGE), identified 22 patterns. PFGE type A, closely related to the PFGE type of the previously identified New York clone, accounted for 154 (60%) of 258 isolates. The clone was detected in all facilities, was predominant in 19 of the 29 health care centers, and accounted for 92% of the MRSA isolates collected in PA. The overwhelming majority of MRSA with PFGE type A was also resistant to erythromycin, ciprofloxacin, and clindamycin. One of the two most common PFGE subtypes detected in the three states sampled (PFGE subtype A1) had an identical PFGE pattern to that of the previously described vancomycin-resistant strain of S. aureus (VISA) recently detected in a hospital in Westchester, NY. The second most frequent MRSA clone with PFGE type E and accounting for 26% (68/258 isolates), also described earlier in the 12 New York City hospitals, was resistant not only to erythromycin, ciprofloxacin, and clindamycin, but also to gentamicin and sulfamethoxazole-trimethoprim as well. The unique multidrug resistance pattern of this second clone and its geographic distribution accounted for the differences observed in the frequency of multidrug resistance among MRSA isolates recovered in the three states. The pandemic Iberian clone recently detected in New York City was not detected among the 258 MRSA isolates recovered in CT, NJ, and PA.
Using constraint sets to achieve delay bounds in CIOQ switches (2003)

We previously proposed constraint sets as a simple technique to analyze routers with a single stage of buffering. We extend the technique to analyze combined input and output (CIOQ) routers with two stages of buffering.
Mindlin's friction term and implications for shear modulus and anisotropy in granular media (2011)

Effective elastic moduli expressions as a function of Mindlin's contact friction term for a random packing (porosity ∼36%) of identical isotropic spheres under either hydrostatic or uniaxial compression are derived. The motivation behind our approach is to incorporate the effect of intergrain contact friction in the prediction of velocities and stress‐induced velocity anisotropy in unconsolidated sands. The Mindlin friction term, allowing partial slip across the contact area between pairs of spheres, can be viewed as a parameter accounting for the growing macroscopic intergrain friction in sands as burial progresses. Hence, both moduli and velocities will gradually increase as the compressional to shear wave velocity ratio or Poisson's ratio decreases. Estimate of effective elastic constants can be obtained for a spherical grain pack with an arbitrary frictional behavior between two special contact boundary conditions representing infinite and near zero grain‐to‐grain friction. Our model predicts a non‐linear transition between the two special grain contact conditions when compared to published linear relationships. Comparison of elastic moduli, anisotropy, velocity predictions with experimental data on loose sand samples undergoing both hydrostatic and uniaxial compression, match reasonably well.
Estrogen Receptor α, but Not β, Is Required for Optimal Dendritic Cell Differentiation and CD40-Induced Cytokine Production (2008)

Dendritic cells (DC) are critical actors in the initiation of primary immune responses and regulation of self-tolerance. The steroid sex hormone 17beta-estradiol (E(2)) has been shown to promote the differentiation of DCs from bone marrow (BM) precursors in vitro. However, the estrogen receptor (ER) involved in this effect has not yet been characterized. Using recently generated ERalpha- or ERbeta-deficient mice, we investigated the role of ER isotypes in DC differentiation and acquisition of effector functions. We report that estrogen-dependent activation of ERalpha, but not ERbeta, is required for normal DC development from BM precursors cultured with GM-CSF. We show that reduced numbers of DCs were generated in the absence of ERalpha activation and provide evidence for a cell-autonomous function of ERalpha signaling in DC differentiation. ERalpha-deficient DCs were phenotypically and functionally distinct from wild-type DCs generated in the presence of estrogens. In response to microbial components, ERalpha-deficient DCs failed to up-regulate MHC class II and CD86 molecules, which could account for their reduced capacity to prime naive CD4(+) T lymphocytes. Although they retained the ability to express CD40 and to produce proinflammatory cytokines (e.g., IL-12, IL-6) upon TLR engagement, ERalpha-deficient DCs were defective in their ability to secrete such cytokines in response to CD40-CD40L interactions. Taken together, these results provide the first genetic evidence that ERalpha is the main receptor regulating estrogen-dependent DC differentiation in vitro and acquisition of their effector functions.
Use cases for CoRE security (2013)

This document presents use cases for security measures in scenarios
involving constrained RESTful devices. Special focus is placed on
access control and authentication. Where specific details are
relevant, it is assumed that the devices use CoAP as communication
protocol, however most conclusions apply generally. A number of
security requirements are derived from the use cases, which are
intended as a guideline for developing a comprehensive authentication
and authorization approach for this class of scenarios.
How Do Roots Control Xylem Sap ABA Concentration in Response to Soil Drying? (1997)

Maize (Zea mays L.) and Leucaena leucocephala (a tropical tree) were subjected to different degrees of soil drying and changes in their root and xylem ABA concentrations were measured simultaneously. Additional treatments such as defoliation, light sheltering and stem girdling were applied so that phloem transport into roots was manipulated. When soil was dried, ABA concentration in xylem sap increased almost linearly with that of roots in both species. Such an increase was relatively plateaued at high root ABA concentrations, suggesting that severe soil drying might have hindered some parts of roots from delivering ABA into xylem flow. When 3 H-ABA was load
Temperature-Dependent Induction of Salicylic Acid and Its Conjugates during the Resistance Response to Tobacco Mosaic Virus Infection (1992)

Temperature-induced neutral-ionic transition in dimethyltetrathiafulvalene-p-chloranil (1993)

A new 1:1 mixed-stack organic charge-transfer crystal of 2,6-dimethyltetrathiafulvalene-p-chloranil (DMTTF-CA), which undergoes a temperature-induced neutral-ionic transition (TINIT), was reported. At a critical temperature of 65\ifmmode\pm\else\textpm\fi{}5 K the molecular ionicity and the stack dimerization were found to change discontinuously. A most striking feature in the phase transition of DMTTF-CA was that a neutral-ionic coexisting phase did appear at lower temperatures, unlike the homogeneous ionic phase observed for the TINIT of tetrathiafulvalene-p-chloranil (TTF-CA). These transition characteristics were discussed by taking into account the structural differences between these two complexes composed of similar constituents.
Dual-Functional Energy-Harvesting and Vibration Control: Electromagnetic Resonant Shunt Series Tuned Mass Dampers (2013)

This paper proposes a novel retrofittable approach for dual-functional energy-harvesting and robust vibration control by integrating the tuned mass damper (TMD) and electromagnetic shunted resonant damping. The viscous dissipative element between the TMD and primary system is replaced by an electromagnetic transducer shunted with a resonant RLC circuit. An efficient gradient based numeric method is presented for the parameter optimization in the control framework for vibration suppression and energy harvesting. A case study is performed based on the Taipei 101 TMD. It is found that by tuning the TMD resonance and circuit resonance close to that of the primary structure, the electromagnetic resonant-shunt TMD achieves the enhanced effectiveness and robustness of double-mass series TMDs, without suffering from the significantly amplified motion stroke. It is also observed that the parameters and performances optimized for vibration suppression are close to those optimized for energy harvesting, and the performance is not sensitive to the resistance of the charging circuit or electrical load.
Predicting cloud resource utilization (2016)

A major challenge in Cloud computing is resource provisioning for computational tasks. Not surprisingly, previous work has established a number of solutions to provide Cloud resources in an efficient manner. However, in order to realize a holistic resource provisioning model, a prediction of the future resource consumption of upcoming computational tasks is necessary. Nevertheless, the topic of prediction of Cloud resource utilization is still in its infancy stage.
Evaluation of different cryoprotective agents in maintenance of viability of Helicobacter pylori in stock culture media. (2010)

Four different cryoprotective supplemented stock media were evaluated for maintaining better survival and recovery of H. pylori type strain NCTC 11637 at two different maintenance temperatures of -20°C and -80°C after one month preservation as frozen stocks. The spread plate colony count method was used to investigate the recovery rate of H. pylori from equally inoculated bacterial suspensions in differently prepared stock cultures. After the preservation of H. pylori for one month in different cryoprotectant-supplemented stock media, the recovery rates for -20°C obtained for stock cultures supplemented with dimethyl sulfoxide (DMSO), polyethylene glycol (PEG), glycerol and glycerol+sucrose, as well as controls with and without human serum alone were 7.13, 6.97, 7.93, 7.99, 6.95 and 0.0 log CFU/ml, respectively. Maintenance of bacteria at -80°C gave statistically higher recovery rates compared to preservation at -20°C with the values of 8.55, 8.24, 8.59, 8.66, 8.01 and 0.0 log CFU/ml for these above mentioned stock cultures. The stock cultures supplemented with glycerol+sucrose and glycerol showed the highest recovery rates, 7.99 and 7.93 for -20°C vs. 8.66 and 8.59 for -80°C respectively, which were statistically different from the others. Our study revealed that H. pylori type strain NCTC 11637 could be better preserved at -80°C than -20°C. The best stock media which supported viability or culturability of bacteria were brain heart infusion broth (BHI)+glycerol+human serum and BHI+glycerol+sucrose+human serum, where the latter yielded the higher recovery rate.
Tri-state current source inverter with improved dynamic performance (2006)

Traditional dc-ac current source inverter (CSI) has a right-half-plane (RHP) zero in its control-to-output transfer function. This RHP zero causes the inverter output to fall before rising when a step increase in command reference is required (commonly known as non-minimum-phase effect). To achieve a better dynamic response, this paper proposes the design of a tri-state CSI using only an additional semiconductor switch for introducing unique free-wheeling states to the traditional six active and three null states of a CSI. With the free-wheeling states inserted appropriately within the inverter state sequence, the inductive boosting and discharging intervals can be decoupled, allowing the RHP zero to be eliminated with only minor circuit modifications (high level control schemes like predictive and multi-loop voltage/current control remain unchanged). The designed inverter can be controlled using an appropriately formulated digital pulse-width modulation algorithm, which can conveniently be implemented using a digital signal processor with an on-chip carrier-based modulator and an external digital programmable logic device. The resulting inverter is tested by simulation and experimentally using a laboratory prototype for demonstrating its improved dynamic performance with no commutation difficulties introduced.
Thyroglobulin in Washout Fluid From Lymph Node Fine-needle Aspiration Biopsy in Papillary Thyroid Cancer: Large-scale Validation of the Cutoff Value to Determine Malignancy and Evaluation of Discrepant Results (2013)

Our results validated 1.0 ng/mL of FNA-Tg as a cutoff value for diagnosing LN metastasis of PTC and suggested that serum TSH suppression and serum Tg presence should be considered in diagnosing LN malignancy with FNA-Tg in PTC patients.
Plaque rupture with severe pre-existing stenosis precipitating coronary thrombosis. Characteristics of coronary atherosclerotic plaques underlying fatal occlusive thrombi. (1983)

Ruptured atheromatous plaques were identified by step-sectioning technique as responsible for 40 of 51 recent coronary artery thrombi and 63 larger intimal haemorrhages. The degree of pre-existing luminal narrowing at the site of rupture was decisive for whether plaque rupture caused occlusive thrombosis or just intimal haemorrhage. If the pre-existing stenosis was greater than 90% (histologically determined) then plaque rupture nearly always caused occlusive thrombosis. Clearly indicating the primary role of plaque rupture in thrombus formation were the frequent finding of plaque fragments deeply buried in the centre of the thrombus and the nature of the thrombus at the site of rupture where it consisted predominantly of platelets. Thus, a severe chronic stenosis seems to be a prerequisite for occlusive thrombus formation, but the thrombotic process itself is triggered by an acute intimal lesion.
[A case of primary osteosarcoma of the liver]. (1990)

The authors report a case of primary osteosarcoma of the liver in a 75 year-old man with post hepatitic B cirrhosis. The hepatic tumor was discovered on ultrasound and computed tomography. Angiography showed a hypervascularized tumor. The patient died rapidly. Diagnosis of primary osteosarcoma of the liver was established through histopathological examination of post mortem specimens and was confirmed by immunohistochemical study. From this and two other previously reported cases the authors describe the different primary hepatic tumors mimicking osteosarcoma.
Mechanisms of ageing in chronic allograft nephropathy (2006)

Background. Chronic allograft nephropathy (CAN) is the single most important cause of late graft loss. Histologic signs of CAN overlap with the histology of normally ageing kidneys. Clinical observations show an inverse relationship between either donor age or ischemia time and long-term graft survival. The mechanisms by which donor age or ischemia lead to reduced functional lifespan are currently unknown. Material and methods. A review of the current literature on renal transplantation, ageing mechanisms and advances in the molecular pathogenesis of CAN was performed. Results and conclusions. Ischemia time and donor age have been identified as major allo-antigen-independent risk factors. Following transplantation, reactive oxygen species cause oxidative DNA and telomeric damage. Evidence for a molecular connection between oxidative DNA damage and ageing has increased, and suggests that the mechanisms causing normal ageing and long-term organ dysfunction may be fundamentally the same. The accelerated appearance of ageing phenotypes in transplanted organs has been shown in several studies. Together with the deleterious ongoing allogeneic immune response of the recipient, this leads to accelerated exhaustion of the regenerative capacity of the kidney, and eventually to dysfunction of the renal allograft.
CHARACTERIZATION OF AAC(6')-APH(2"), A BIFUNCTIONAL AMINOGLYCOSIDE MODIFYING ENZYME (2003)

AAC(6')-APH(2") is a bifunctional enzyme which catalyzes the inactivation of aminoglycoside antibiotics by ATP-dependant O-phosphorylation and acetyl coenzyme A-dependant N- and O-acetylation. it is the most prominent aminoglycoside-modifying enzyme found in gentamicin-resistant clinical isolates of Enterococci and Staphylococci. Although capable of inactivating all 2-deoxystreptamine aminoglycosides, gentamicin is the most clinically important substrate commonly administered in combination therapies to treat nosocomial Enterococcal infections. Gentamicin-resistant clinical isolates carrying aac(6')-aph(2") are characterized by high level resistance to gentamicins and other aminoglycosides. In an attempt to obtain a more thorough understanding of it's functionalities and develop strategies to inhibit its' function in vivo, studies were initiated to characterize the substrate specificities, the regiospecificities of inactivation, and the potential for generation of lead compounds with inhibitory action towards AAC(6')-APH(2"). The studies reported herein, identify: i) two novel activities exhibited by AAC(6')-APH(2") (a Serine protein kinase activity exhibited by the phosphoransferase APH(2")-Ia and an O-acetyltransfer activity exhibited by the acetyltransferase AAC(6')-Ie, ii) the substrate structural requirements for enzyme/substrate interactions, iii) an unanticipated regiospecificity of inactivation of the 4, 5-disubstituted aminoglycosides and iv) inhibition of the APH(2")-Ia by isoquinolinesulfonamide protein kinase inhibitors.
Ultrafast signatures of spin and orbital order in antiferromagnetic $\alpha$-Sr$_2$CrO$_4$. (2021)

We used femtosecond optical spectroscopy to study ultrafast spin and orbital ordering dynamics in the antiferromagnetic Mott insulator $\alpha$-Sr$_2$CrO$_4$. This chromate system possesses multiple spin and orbital ordered phases, and therefore could enable us to study the unique interplay between these collective phases through their non-equilibrium response to photoexcitation. Here, by varying the pump photon energy, we selectively drove inter-site spin hopping between neighboring Cr $t_{2g}$ orbitals and charge transfer-type transitions between oxygen 2$p$ and Cr $e_{g}$ orbitals. The resulting transient reflectivity dynamics revealed temperature-dependent anomalies across the N${\textrm{\'e}}$el temperature for spin ordering as well as the transition temperatures linked to different types of orbital order. Our results reveal distinct relaxation timescales for spin and orbital orders in $\alpha$-Sr$_2$CrO$_4$ and provide experimental evidence for the phase transition at $T_\textrm{O}$, possibly related to antiferro-type orbital ordering.
