Miura-Ori Inspired Smooth Sheet Attachments for Zipper-Coupled Tubes (2022)

Zipper-coupled tubes are a broadly applicable, deployable mechanism with an angular surface that can be smoothed by attaching an additional smooth sheet pattern. The existing design for the smooth sheet attachment, however, leaves small gaps that can only be covered by adding flaps that unfold separately, limiting applicability in situations requiring a seamless surface and simultaneous deployment. We provide a novel construction of the smooth sheet attachment that unfolds simultaneously with zipper-coupled tubes to cover the entire surface without requiring additional actuation and without inhibiting the tubes’ motion up to an ideal, unfolded state of stability. Furthermore, we highlight the mathematics underlying the design and motion of the new smooth sheet pattern, thereby demonstrating its rigid-foldability and compatibility with asymmetric zipper-coupled tubes.
Prediction of retweet cascade size over time (2012)

Retweet cascades play an essential role in information diffusion in Twitter. Popular tweets reflect the current trends in Twitter, while Twitter itself is one of the most important online media. Thus, understanding the reasons why a tweet becomes popular is of great interest for sociologists, marketers and social media researches. What is even more important is the possibility to make a prognosis of a tweet's future popularity. Besides the scientific significance of such possibility, this sort of prediction has lots of practical applications such as breaking news detection, viral marketing etc. In this paper we try to forecast how many retweets a given tweet will gain during a fixed time period. We train an algorithm that predicts the number of retweets during time T since the initial moment. In addition to a standard set of features we utilize several new ones. One of the most important features is the flow of the cascade. Another one is PageRank on the retweet graph, which can be considered as the measure of influence of users.

Magnesium salts exert direct vasodilator effects on rat cremaster muscle microcirculation. (1989)

In vivo microscopic observations were made on arterioles and venules (10-20 microns i.d.) of the rat cremaster muscle circulation, using an image-splitting eyepiece and high-resolution TV image-intensification, in order to determine the microvascular effects of inorganic and organic magnesium (Mg) salts. MgSO4, MgCl2, Mg aspartate HCl, and Mg acetate were administered perivascularly and intravenously. Topical application (10(-2) to 10(1) mumol) and intravenous (i.v.) administration (5-400 mumol/kg/min) of all Mg salts, [which resulted in elevated plasma Mg levels (1.1-4.7 mg/dl over controls)], brought about rapid, almost instantaneous vasodilation of both arterioles and venules in low doses. Intravenous administration of Mg salts resulted in elevation of plasma calcium (0.5-1.5 mg/dl over controls) and decreases in plasma phosphate (0.5-1.2 mg/dl below controls); plasma Na and K were not affected. High doses (i.e. 400 mumol/kg/min) of some Mg salts, administered i.v., tended to constrict these microvessels. Diastolic and systolic arterial blood pressure as well as heart rate decreased in a dose-dependent manner upon systemic administration of all 4 Mg salts. Intravenous administration of high doses of the Mg salts (i.e., greater than 200 mumol/kg/min) often resulted in marked falls in mean arterial blood pressure (e.g. 110 to 40 mmHg) and heart rate (e.g. 460 to 130 bpm), followed by death. Administration of a variety of pharmacological antagonists and a cyclo-oxygenase inhibitor did not interfere with vasodilatation of arterioles or venules induced by Mg salts. Use of hyperosmolar sucrose partially mimicked some of the vasodilator, but not the cardiac or blood pressure lowering actions of Mg salts. These data indicate that magnesium ions: 1) bring about vasodilatation without releasing adrenergic amines, histamine, serotonin, acetylcholine, prostaglandins, or endogenous opioids; 2) are direct, potent vasodilators of intact rat cremaster muscle microvessels; 3) may have a depressive action on heart; 4) exert these microvascular and cardiac actions in low doses and 5) can produce severe hypotension and bradycardia only after i.v. administration of high doses. In addition, acute administration of various Mg salts can rapidly alter certain plasma electrolytes (e.g., Ca, PO4), at least in rats, which may be related to the microvascular actions of Mg2+.
Zeolite synthesis in hydrated silicate ionic liquids (2014)

Hydrated alkali silicate ionic liquids (HSIL) were prepared by hydrolysis of tetraethoxysilane (TEOS) in alkali hydroxide-water mixtures, inducing coacervation and phase separation. The resulting optically clear, homogenous silicate ionic liquid offers exceptional potential for monitoring zeolite crystallisation. This enhanced synthesis route provides access to analysis of speciation, mechanistic details of zeolite formation, and brings organic-template-free zeolite synthesis by design within reach.
Airports and Environmental Problems (1971)

&lt;div class="htmlview paragraph"&gt;Various factors are changing the nature of the arena in which decisions affecting the air transportation industry are made. Public concern about the deterioration of the environment is among the chief factors. The responses to, and outcomes of this public pressure are becoming visible. The ability of the existing governmental-industrial relationship to cope with the necessity of reordering both their own and the public's priorities to place the environment on a higher level is being tested and assessed. It will be several years before the capability and willingness of the current system to make the necessary adjustments can be judged. However, enough time has now passed that some preliminary judgments can be made and possibilities foreseen.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;The air transportation industry has, in the last twenty-five years, undergone a period of unparalleled expansion. The fact that it is now possible to get from almost anywhere to almost anywhere in a matter of hours has had a great impact on business, governmental, and even social interactions. The technological advances which have made this explosive growth possible are indeed impressive. To many people, however, it is now becoming apparent that the constant deferring to future generations of the social costs of this economic activity and technological advance must stop; and that the subsidization of the air transportation industry, as well as many others, in the currency of social cost must be greatly reduced if not ended.&lt;/div&gt;
A Ruler for Determining the Position of Proteins in Membranes (2005)

Both the oxygen diffusion rate and the oxygen solubility vary with depth into the interior of biological membranes. The product of these two gradients generates a single gradient, a permeability gradient, which is a smooth continuous function of the distance from the center of the membrane. Using electron paramagnetic resonance and the spin-probe method, the relaxation gradient of oxygen, which is directly proportional to the permeability gradient, is the quantity that can be directly measured in membranes under physiological conditions. The gradient obtained provides a calibrated ruler for determining the membrane depth of residues either from loop regions of membrane-binding proteins or from the membrane-exposed residues of transmembrane proteins. We have determined the relaxation gradient of oxygen in zwitterionic and anionic phospholipid membranes by attaching a single nitroxide probe to a transmembrane alpha-helical polypeptide at specific residues. The peptide ruler was used to determine the depth of penetration of the calcium-binding loops of the C2 domain of cytosolic phospholipase A(2). The positions of selected residues of this membrane-binding protein that penetrate into the membrane, determined using this ruler, compared favorably with previous determinations using more complex methods. The relaxation gradient constrains the possible values of the membrane-dependent oxygen concentration and the oxygen diffusion gradients. The average oxygen diffusion coefficient is estimated to be at least 2-fold smaller in the membrane than that in water.
Effect of Turbulence on Orifice Meter Performance (1994)

Mean and turbulent velocity profiles downstream of a 19-tube bundle are presented. Experiments have been carried out in 101.6-mm-dia piping configuration at prevalent atmospheric conditions with air as the fluid. The two cases considered are: one with the tube bundle placed in good flow conditions and the other with the tube bundle used as a sliding vane downstream of a single 90-deg elbow. In both cases, for various positions of the tube bundle with respect to an orifice plate, the discharge coefficient for the orifice plate has been compared to a baseline value. The results indicate that it is possible to correlate the deviations in the discharge coefficient to the mean and turbulent velocity field upstream of the orifice.

Ordered Nanoporous Nitrogen- and Oxygen-Codoped Carbon Nanospheres as Electrocatalysts for Oxygen-Reduction Reaction in Direct Methanol Fuel Cells (2020)

Metal-free carbon materials are currently of considerable interest to researchers because they have a proven ability to catalyze many electrochemical processes. Making such materials with an abundant amount of nanopores and large specific surface area, and thereby a large density of accessible electrochemically active sites, can enhance their catalytic activities. To this end, herein we report three-dimensional (3D) nanoporous metal-free carbon nanospheres (<200 nm in diameter) with oxygen and nitrogen dopant atoms and high surface area that show superior catalytic activity to reduce oxygen. Compared with 40 wt % Pt/C that is obtained from a commercial supplier, these nanospheres electrocatalyze this reaction in 0.1 M KOH electrolyte with a better onset potential and a similar half-potential. We also show that the nanospheres can be successfully applied as electrocatalysts on the cathode electrode of a direct methanol fuel cell, together with PtRu/C electrocatalyst obtained from a commercial source at the anode. With this cell, a high amount of energy at a power density of 20 mW cm–2 at 15 °C is received. Furthermore, the nanospheres can tolerate a possible methanol crossover reaction reasonably well during their operation in the fuel cell.
Proteomic Identification of Interleukin-2 Therapy Response in Metastatic Renal Cell Cancer (2007)

We identified and validated a proteomic pattern that is an independent predictor of the interleukin-2 response. The ability to predict the probability of the interleukin-2 response could permit targeted selection of the patients most likely to respond to interleukin-2, while avoiding unwanted toxicity in patients less likely to respond. This proteomic predictor has the potential to significantly aid clinicians in the decision making of appropriate therapy for patients with metastatic renal cell carcinoma.
Familial isolated pituitary adenomas and AIP gene mutations (2013)

Inherited genetic conditions associated with pituitary tumours are rare and include multiple endocrine neoplasia type 1 (MEN1) and Carney complex. Such hereditary pituitary adenomas are of great interest genetically and clinically as they can permit precocious diagnosis of tumors in carriers of genetic mutations, and as clinical evidence suggests that these tumors may be more aggressive than general sporadic equivalents. In 2000 the first series of 27 patients with a new hereditary tumor condition, familial isolated pituitary adenomas (FIPA) that is unrelated to other syndromes has been described in Liège. In 2006, Vierimaa and coworkers described AIP as a gene assosiated with predisposition to pituitary adenomas in familial setting. AIP mutations were found in 20.4% of FIPA families (36.1% in families homogeneous for GH secretion). In FIPA families, adenomas usually occur earlier and are more aggressive than in sporadic cases. We have also showed that patients with AIP mutations in the FIPA setting are predominantly male and have larger and more aggressive tumors that occur more than 10 years before those without AIP mutations. Responses to treatment may not be as favourable in AIP mutated patients. All types of pituitary adenomas can occur in FIPA cases regardless their AIP status. However in AIP mutated patients, GH or GH + PRL secreting adenomas are predominant. In a study of 76 young patients with Cushings disease, only one had an AIP mutation. In another study of more than 150 supposedly sporadic adenomas in young patients (less than 30 years) with macro-adenomas more than 15 % had AIP mutations (all of which were GH or PRL secreting). FIPA is not uncommon (approximately 2% of all pituitary adenomas). AIP mutation screening should be considered in all patients with FIPA and in young patients suffering from aggressive GH or PRL secreting adenomas.
American Society for Enhanced Recovery and Perioperative Quality Initiative Joint Consensus Statement on Patient-Reported Outcomes in an Enhanced Recovery Pathway (2017)

Patient-reported outcomes (PROs) are measures of health status that come directly from the patient. PROs are an underutilized tool in the perioperative setting. Enhanced recovery pathways (ERPs) have primarily focused on traditional measures of health care quality such as complications and hospital length of stay. These measures do not capture postdischarge outcomes that are meaningful to patients such as function or freedom from disability. PROs can be used to facilitate shared decisions between patients and providers before surgery and establish benchmark recovery goals after surgery. PROs can also be utilized in quality improvement initiatives and clinical research studies. An expert panel, the Perioperative Quality Initiative (POQI) workgroup, conducted an extensive literature review to determine best practices for the incorporation of PROs in an ERP. This international group of experienced clinicians from North America and Europe met at Stony Brook, NY, on December 2-3, 2016, to review the evidence supporting the use of PROs in the context of surgical recovery. A modified Delphi method was used to capture the collective expertise of a diverse group to answer clinical questions. During 3 plenary sessions, the POQI PRO subgroup presented clinical questions based on a literature review, presented evidenced-based answers to those questions, and developed recommendations which represented a consensus opinion regarding the use of PROs in the context of an ERP. The POQI workgroup identified key criteria to evaluate patient-reported outcome measures (PROMs) for their incorporation in an ERP. The POQI workgroup agreed on the following recommendations: (1) PROMs in the perioperative setting should be collected in the framework of physical, mental, and social domains. (2) These data should be collected preoperatively at baseline, during the immediate postoperative time period, and after hospital discharge. (3) In the immediate postoperative setting, we recommend using the Quality of Recovery-15 score. After discharge at 30 and 90 days, we recommend the use of the World Health Organization Disability Assessment Scale 2.0, or a tailored use of the Patient-Reported Outcomes Measurement Information System. (4) Future study that consistently applies PROMs in an ERP will define the role these measures will have evaluating quality and guiding clinical care. Consensus guidelines regarding the incorporation of PRO measures in an ERP were created by the POQI workgroup. The inclusion of PROMs with traditional measures of health care quality after surgery provides an opportunity to improve clinical care.
P‐231L: Late‐News Poster : A Wide Viewing Angle Transflective IPS LCD Applying New Optical Design (2006)

Abstract Viewing angle performance of transflective LCDs, affected by many optical parameters such as Nz of retardation films and azimuth of slow axis, is improved when the optical parameters obey a simple rule. A new optical design is deduced from the rule, and applied for transflective IPS‐LCD with a single gap structure and a twisted liquid crystal layer. A viewing angle performance comparable to transmissive IPS LCDs is realized in transflective IPS‐LCD.
Application of the Doylestown algorithm for the early detection of hepatocellular carcinoma (2018)

We previously developed a logistic regression algorithm that uses AFP, age, gender, ALK and ALT levels to improve the detection of hepatocellular carcinoma (HCC). In 3,158 patients from 5 independent sites, this algorithm, referred to as the "Doylestown" algorithm, increased the AUROC of AFP 4% to 12% and had equal benefit regardless of tumor size or the etiology of liver disease.
Integrated Circuit Implantable Telemetry Systems (1983)

A series of totally implantable telemetry systems have been developed to chronically determine such parameters as blood flow, pressure, biopotentials and temperature. This instrumentation is currently used in medical research involving laboratory animals. Custom integrated circuits are used to realize the signal processing complexity needed for accurate and stable measurements within the size and power constraints of an implantable electronics system.
Combining metrics for mesh simplification and parameterization (2005)

We present a mesh simplification strategy for generating polygonal meshes with well-shaped faces in the presence of constraints. We introduce a novel combination of metrics to drive the simplification process while generating high-quality meshes. Our method handles the creation of coarse triangle or triangle/quad meshes with tagged features. The metrics favor "ideal" vertex valences (six or four) and element shapes (equilateral triangles or rectangles). We illustrate this method in the context of remeshing and texture-mapping scenarios.
Novel CDTA-based, Bifunctional Chelators for Stable and Inert MnII Complexation: Synthesis and Physicochemical Characterization (2017)

In the search for Mn<sup>II</sup> MR and PET/MR imaging agents with optimal balance between thermodynamic stability, kinetic inertness, and relaxivity, two novel bifunctional Mn<sup>II</sup> chelators (BFMnCs) based on CDTA (trans-1,2-diaminocyclohexane-N,N,N',N'-tetraacetic acid) were synthesized. A six-step synthesis, involving the buildup of a functionalized trans-1,2-diaminocyclohexane core, provided CuAAC-reactive 6a and 6b bearing an alkyne or azide substituent on the cyclohexane ring, respectively (CuAAC = Cu<sup>I</sup>-catalyzed azide-alkyne 1,3-dipolar cycloaddition). Thermodynamic, kinetic, and relaxometric studies were performed with 4-HET-CDTA (8a) as a "model chelator," synthesized in two steps from 6a. The protonation constants revealed that 8a is slightly less basic than CDTA and forms a Mn<sup>II</sup> complex of marginally lower thermodynamic stability (log K<sub>MnL</sub> = 13.80 vs 14.32, respectively), while the conditional stability constant is almost identical for both chelates (pMn = 8.62 vs 8.68, respectively). Kinetic assessment of the Cu<sup>II</sup>-mediated transmetalation of [Mn(4-HET-CDTA)]<sup>2-</sup> showed that proton-assisted complex dissociation is slightly slower than for [Mn(CDTA)]<sup>2-</sup> (k<sub>1</sub> = 297 vs 400 M<sup>-1</sup> s<sup>-1</sup>, respectively). Importantly, the dissociation half-life near physiological conditions (pH 7.4, 25 °C) underlined that [Mn(4-HET-CDTA)]<sup>2-</sup> is ∼35% more inert (t<sub>1/2</sub> = 16.2 vs 12.1 h, respectively). Those findings may be accounted for by a combination of reduced basicity and increased rigidity of the ligand. Analysis of the <sup>17</sup>O NMR and <sup>1</sup>H NMRD data attributed the high relaxivity of [Mn(4-HET-CDTA)]<sup>2-</sup> (r<sub>1</sub> = 4.56 mM<sup>-1</sup> s<sup>-1</sup> vs 3.65 mM<sup>-1</sup> s<sup>-1</sup> for [Mn(CDTA)]<sup>2-</sup>; 20 MHz, 25 °C) to slower rotational dynamics (τ<sub>R</sub><sup>298</sup> = 105 ps). Additionally, the fast water exchange of the complex correlates well with the value reported for [Mn(CDTA)]<sup>2-</sup> (k<sub>ex</sub><sup>298</sup> = 17.6 × 10<sup>7</sup> vs 14.0 × 10<sup>7</sup> s<sup>-1</sup>, respectively). Given the exquisite compromise between thermodynamic stability, kinetic inertness, and relaxivity achieved by [Mn(4-HET-CDTA)]<sup>2-</sup>, appropriately designed CuAAC-conjugates of 6a/6b are promising precursors for the preparation of targeted, bioresponsive, or high relaxivity manganese-based PET/MR tracers (<sup>52g/55</sup> Mn<sup>II</sup>) and MR contrast agents (Mn<sup>II</sup>).
Translating Cyber-Physical Control Application Requirements to Network level Parameters (2020)

Cyber-physical control applications impose strict requirements on the reliability and latency of the underlying communication system. Hence, they have been mostly implemented using wired channels where the communication service is highly predictable. Nevertheless, fulfilling such stringent demands is envisioned with the fifth generation of mobile networks (5G). The requirements of such applications are often defined on the application layer. However, cyber-physical control applications can usually tolerate sparse packet loss, and therefore it is not at all obvious what configurations and settings these application level requirements impose on the underlying wireless network. In this paper, we apply the fundamental metrics from reliability literature to wireless communications and derive a mapping function between application level requirements and network level parameters for those metrics under deterministic arrivals. Our mapping function enables network designers to realize the end-to-end performance (as the target application observes it). It provides insights to the network controller to either enable more reliability enhancement features (e.g., repetition), if the metrics are below requirements, or to enable features increasing network utilization, otherwise. We evaluate our theoretical results by realistic and detailed simulations of a factory automation scenario. Our simulation results confirm the viability of the theoretical framework under various burst error tolerance and load conditions.
