Authors: Siregar Muhammad Sapril , Kusturi Nanda Afra , Hartati Diah Vitaloka 
Published: December 2024

This study aimed to figure out cadets responses toward the implementation of Cadets Innovation Creation Corner in increasing cadets speaking ability. The cadet corner is a place and activities for cadets to practice their speaking English based on their respective majors. The place includes nautical, engineering and electrical class. The activities that they do they will try to make a creation based on their major and try to explain it in English. The goal is that they get used to explaining the tools they use on the ship according to their field. this makes them accustomed to speaking in English and remembering vocabulary, working methods and tools they often use. The qualitative method was used to collect the data. The sample was the second-grade cadets of Merchant Marine Polytechnic of Malahayati, which consisted of 22 cadets. The open-ended questionnaire was distributed as the instrument for collecting the data. It consists of three questions that relate to cadets opinions on this strategy. The data was analyzed by using an interactive model. The result of this study indicated that there were positive responses of the cadets toward English Cadets Corner activity implementation in increasing their speaking ability. Most cadets consider this strategy was beneficial in supporting their speaking in English. The cadets opinions were categorized into agree and disagree group participants. The implementation of English cadets corner activities was very useful in increasing cadets speaking ability in English, especially about their major. Therefore, the other university could also use this strategy to support the cadets’ speaking ability in other genres of English.

More Evidence of Microscopic Ball Lightning (Plasmoids) in CF
Authors: Lewis Edward 
Published: December 2024

The traces and marks of micrometer-sized plasmoids have been found in many transmutation and cold fusion experiments. This author has counted about 12 groups that have published photographs that show such microscopic markings on their electrodes, experimental apparatus, X-ray films, or particle track-detecting nuclear emulsions. Twenty years ago, this author proposed a theory that these objects will be commonly produced in these kinds of devices. A survey article of such markings and traces exhibited in various experiments from the year 2000 to 2007 was published in this journal in 2009. In it, the author compared the markings to those previously detected by T. Matsumoto and K. Shoulders. In this letter, markings and features that were published more recently by Mosier-Boss et al. and Adamenko et al. are described. The author believes that this kind of highly anomalous microscopic plasmoid is similar to macroscopic natural ball lightning and so calls these objects “microscopic ball lightning.” The author proposes that more focus on investigating these objects will greatly enhance the researchers’ understanding of the processes involved in atomic transmutations.
Impact of Electrical Avalanche through a ZrO2–NiD Nanostructured CF/LANR Component on its Incremental Excess Power Gain
Authors: Swartz Mitchell R. , Verner Gayle , Hagelstein Peter L. 
Published: December 2024

Cold fusion nanomaterials, in general, and NANOR⃝R -type LANR components (derived from them), in particular, have two distinct regions of performance on each side of the electrical avalanche. This had lead to the identification of three (3) distinct regions of their electrical operation. We now report that the optimal power gain of NANOR⃝R -type cold fusion components is found far below the breakdown voltage and that the power gain decreases continuously as the electrical avalanche threshold is approached. Beyond the region of electrical avalanche, the previously active preloaded LANR quantum electronic components then give a thermal output similar to a standard ohmic control (a carbon composition resistor). Therefore, use of this technique of driving an active CF/LANR nanomaterial component into, and beyond, their avalanche threshold, provides verification of the excess heat an additional way, which confirms that the calorimetry was calibrated. Also, this investigation indicates where, on the input power axis, to drive them for a maximum effective use. We also report that deuterium can fuel nanomaterial ZrO2–Ni systems, consistent with the previously report involving aqueous CF/LANR systems by Swartz et al. (ICCF-9).
Cooperative Internal Conversion Process
Authors: Kálmán Péter , Keszthelyi Tamás 
Published: December 2024

This paper presents a theoretical discussion of a new phenomenon, called the ‘cooperative internal conversion process’, in which the coupling of bound-free electron and neutron (or proton) transitions due to the dipole term of their Coulomb interaction, which permits cooperation of two nuclei leading to neutron (or proton) exchange if that is allowed by energy conservation. General expressions of the cross section of the processes are reported in the case of one particle nuclear and spherical shell models as well as in the case of free atoms (e.g. noble gases). A half-life characteristic of the process is also determined. As numerical examples, the cooperative internal conversion process by neutron exchange in Ne and by proton exchange in Al are dealt with. The processes may have significance in fields of nuclear waste disposal and nuclear energy production. As a generalization, cooperative internal conversion process by heavy charged particle exchange is discussed, and as an example of it, the cooperative internal conversion process by triton exchange is also discussed.
Mass and Heat Flow Calorimetry in Brillouin’s Reactor
Authors: Tanzella Francis , Godes Robert , Liu Jin , George Robert 
Published: December 2024

Brillouin Energy (BEC) has continued performing calorimetry measurements on the metal (e.g. Ni)/ceramic/Cu coated ceramic tube (catalyst) in a H2 atmosphere with nanosecond pulses applied across the coatings. The Energy Research Center (ERC) has been examining and verifying BEC’s calorimetry for over 18 months since 2 of the calorimeters have been moved from SRI International to BEC’s laboratory. We have continued our testing of new materials, material fabrication techniques, and electrical stimulation methods to produce excess power and energy output. By applying fast pulses of several hundred volts and tens of nanoseconds long, the current follows the “skin-effect” principle and is concentrated at the outer metal–ceramic interface but returns through the bulk of the Cu. Two stimulation methods were used – steady-state and dynamic. In the steady-state method, the pulse power is measured directly using fast oscilloscopes that record the voltage across the catalyst and a shunt resistor in series with the catalyst. The resistance of the shunt resistor is measured accurately under DC and pulse conditions. The input pulse power is determined by multiplying the calculated root-mean-square voltage and current and recorded every 10 s. Using a version of the system identification (SI) heat-flow model designed specifically for the BEC calorimeter, the power reaching the five temperature sensors is determined during simultaneous continuous ramps of both heater and pulse powers. The power emanating from the catalyst is determined during sequences of less frequent, longer duration, low voltage pulses (LVP) and compared to that found using more frequent, shorter duration, high voltage pulses (HVP). The power determined during the less frequent LVP is set as the input power during that sequence. The power of the stimulation pulses during the more frequent HVP sequences is maintained equal to that during the less frequent LVP. Then the calculated power output from the tube is divided by that calculated during the reference sequences, giving a so-called coefficient of performance (COP). We have also used mass flow calorimetry to determine COP. Low voltage, long pulses are chosen to match the input power from high voltage, short pulses. The low voltage pulses are not thought to stimulate LENR, while the high voltage pulses are. This provides a method to compare matching input power under conditions that stimulate LENR with conditions that do not. Any excess heat detected from the high voltage pulse condition is considered to be generated by LENR rather than resistive heating.

Published: July 2019

AbstractRespiratory‐gated volumetric modulated arc therapy (gated VMAT) involves further complexities to the dose delivery process because the gantry rotation must repeatedly stop and restart according to the gating signals. In previous studies, the gantry rotation performances were evaluated by the difference between the plan and the machine log. However, several reports pointed out that log analysis does not sufficiently replicate the machine performance. In this report, a measurement‐based quality assurance of the relation between the gantry angle and gate‐on or gate‐off using triggered kilovoltage imaging and a cylinder phantom with 16 ball bearings is proposed. For the analysis, an in‐house program that estimates and corrects the phantom offset was developed. The gantry angle in static and gated arc delivery was compared between the machine log and the proposed method. The gantry was set every 5 deg through its full motion range in static delivery, and rotated at three speeds (2, 4 and 6 deg s‐1) with different gating intervals (1.5 or 3.0 s) in gated arc delivery. The mean and standard deviation of the angular differences between the log and the proposed method was −0.05 deg ± 0.12 deg in static delivery. The mean of the angular difference was within ±0.10 deg and the largest difference was 0.41 deg in gated arc delivery. The log records the output of the encoder so that miscalibration and mechanical sagging will be disregarded. However, the proposed method will help the users to detect the mechanical issues due to the repeated gantry stops and restarts in gated VMAT.

AbstractPurposeIn this study we calculate composite dose delivered to the prostate by using the Calypso tracking ‐data‐ stream acquired during patient treatment in our clinic. We evaluate the composite distributions under multiple simulated Calypso tolerance level schemes and then recommend a tolerance level.Materials and methodsSeven Calypso‐localized prostate cancer patients treated in our clinic were selected for retrospective analysis. Two different IMRT treatment plans, with prostate PTV margins of 5 and 3 mm respectively, were computed for each patient. A delivered composite dose distribution was computed from Calypso tracking data for each plan. Additionally, we explored the dosimetric implications for “worst case” scenarios by assuming that the prostate position was located at one of the eight extreme corners of a 3 or 5 mm “box.” To characterize plan quality under each of the studied scenarios, we recorded the maximum, mean, and minimum doses and volumetric coverage for prostate, PTV, bladder, and rectum.Results and discussionsCalculated composite dose distributions were very similar to the original plan for all patients. The difference in maximum, mean, and minimum doses as well as volumetric coverage for the prostate, PTV, bladder, and rectum were all < 4.0% of prescription dose. Even for worst scenario cases, the results show acceptable isodose distribution, with the exception for the combination of a 3 mm PTV margin with a 5 mm position tolerance scheme.ConclusionsCalculated composite dose distributions show that the vast majority of dosimetric metrics agreed well with the planned dose (within 2%). With significant/detrimental deviations from the planned dose only occurring with the combination of a 3 mm PTV margin and 5 mm position tolerance, the 3 mm position tolerance strategy appears reasonable, confirming that further reducing prostate PTV margins to 3 mm is possible when using Calypso with a position tolerance of 3 mm.

Published: July 2019

ObjectiveReduced physical function and frailty are common in rheumatoid arthritis (RA). However, relationships between frailty and changes in physical function and disease activity over time in RA are unknown. We tested whether frailty is a risk factor for worsening patient‐reported physical function and disease activity in RA.MethodsAdults from a longitudinal RA cohort (N = 124) participated. By using an established frailty definition, individuals with three or more of the following deficits were considered frail: 1) body mass index less than or equal to 18.5, 2) low grip strength, 3) severe fatigue, 4) slow 4‐m walking speed, and 5) low physical activity. Individuals with one to two or zero deficits were considered “pre‐frail” or “robust,” respectively. Physical function and RA disease activity were assessed by the Health Assessment Questionnaire (HAQ) and Rheumatoid Arthritis Disease Activity Index (RADAI), respectively, at baseline and follow‐up 2 years later. Regression analyses modeled associations of frailty status with change in HAQ and RADAI scores between baseline and follow‐up with and without controlling for covariates. Associations of individual frailty components with change in HAQ and RADAI scores were also examined.ResultsAmong adults with RA, baseline frailty status predicted significant increases, or worsening, in HAQ (β: 0.4; 95% confidence interval: 0.1‐0.8; P < 0.01) but not RADAI scores (β: 0.5; 95% confidence interval: −0.4 to 1.5; P > 0.05) between baseline and follow‐up in fully adjusted models. Fatigue was an important contributor to this effect.ConclusionFrailty may be an important risk factor for reduced physical function over time in RA. Future studies should address whether interventions to reduce frailty improve physical function in RA.

AbstractTin‐based materials are an emerging class of Li‐ion anodes with considerable potential for use in high‐energy‐density Li‐ion batteries. However, the long‐lasting electrochemical performance of Sn remains a formidable challenge due to the large volume changes occurring upon its lithiation. The prevailing approaches toward stabilization of such electrodes involve embedding Sn in the form of nanoparticles (NPs) in an active/inactive matrix. The matrix helps to buffer the volume changes of Sn, impart better electronic connectivity and prevent particle aggregation upon lithiation/delithiation. Herein, facile synthesis of Sn NPs embedded in a SiOC matrix via the pyrolysis of a preceramic polymer as a single‐source precursor is reported. This polymer contains Sn 2‐ethyl‐hexanoate (Sn(Oct)2) and poly(methylhydrosiloxane) as sources of Sn and Si, respectively. Upon functionalization with apolar divinyl benzene sidechains, the polymer is rendered compatible with Sn(Oct)2. This approach yields a homogeneous dispersion of Sn NPs in a SiOC matrix with sizes on the order of 5–30 nm. Anodes of the SiOC/Sn nanocomposite demonstrate high capacities of 644 and 553 mAh g−1 at current densities of 74.4 and 2232 mA g−1 (C/5 and 6C rates for graphite), respectively, and show superior rate capability with only 14% capacity decay at high currents.

AbstractRecent studies of leukemic tumors in individual extramedullary sites showed they adopt the clinical and metastatic behavior of solid cancers originating in those sites. To elucidate features of leukemic tumors that render them resistant to agents effective against marrow leukemia, we analyzed a series of AML breast tumors by histology, immunohistochemistry, and RNA sequencing. Striking histologic similarities to solid cancers were found: a single‐filing architectural pattern virtually identical to that of invasive lobular breast carcinoma and dense desmoplastic keloid‐like fibrosis similar to colon, gallbladder, and pancreas carcinomas. Sequencing found 2157 genes significantly downregulated in AML breast tumors compared to normal breast. Comparison to triple‐negative breast cancer found 859 genes similarly downregulated. At least 30 of these genes have been associated with poor prognosis in breast cancers. Five were reported in AML marrow studies to correlate with poor prognosis. The findings of this pilot study suggest the seed‐and‐soil interaction recognized in solid cancer growth may help explain how leukemic cells, in some patients, adopt solid tumor behavior in non‐marrow sites. Transformed cells that metastasize from tumor to marrow can impart chemoresistance and be an unrecognized cause of treatment failure and death. Further studies comparing leukemic tumor to simultaneous marrow could potentially identify biomarkers that predict extramedullary resistance and lead to new therapeutic targets. Recognizing the potential for leukemia to adopt solid tumor phenotype, and implementation of body scanning and ablative tumor treatment, could decrease the persistently high rates of marrow resistance and treatment failure.

AbstractThe strong electrostatic interactions at the oil–water interface between a small molecule, 5,10,15,20‐tetrakis(4‐sulfonatophenyl)porphyrin, H6TPPS, dissolved in water, and an amine terminated hydrophobic polymer dissolved in oil are shown to produce a supramolecular polymer surfactant (SPS) of H6TPPS at the interface with a binding energy that is sufficiently strong to allow an intermolecular aggregation of the supramolecular polymers. SPSs at the oil–water interface are confirmed by in situ real‐space atomic force microcopy imaging. The assemblies of these aggregates can jam at the interface, opening a novel route to kinetically trap the liquids in non‐equilibrium shapes. The elastic film, comprised of SPSs, wrinkles upon compression, providing a strategy to stabilize liquids in non‐equilibrium shapes.

AbstractBy introduction of four hydroxy (HO) groups into the two perylene bisimide (PBI) bay areas, new HO‐PBI ligands were obtained which upon deprotonation can complex ZnII ions and photosensitize semiconductive zinc oxide thin films. Such coordination is beneficial for dispersing PBI photosensitizer molecules evenly into metal oxide films to fabricate organic–inorganic hybrid interlayers for organic solar cells. Supported by the photoconductive effect of the ZnO:HO‐PBI hybrid interlayers, improved electron collection and transportation is achieved in fullerene and non‐fullerene polymer solar cell devices, leading to remarkable power conversion efficiencies of up to 15.95 % for a non‐fullerene based organic solar cell.
Catalytic Enantioselective Synthesis of 1,4‐Keto‐Alkenylboronate Esters and 1,4‐Dicarbonyls
Authors: Liang Michael Z. , Meek Simon J. 
Published: July 2019

AbstractA catalytic enantioselective method for the synthesis of 1,4‐keto‐alkenylboronate esters by a rhodium‐catalyzed conjugate addition pathway is disclosed. A variety of novel, bench‐stable alkenyl gem‐diboronate esters are synthesized. These easily accessible reagents react smoothly with a collection of cyclic α,β‐unsaturated ketones, generating a new C−C bond and stereocenter. Products are isolated in up to 99 % yield with greater than 20:1 E/Z and greater than 99:1 e.r. Mechanistic studies show the site‐selectivity of transmetalation and reactivity is ligand dependent. The utility of the approach is highlighted by gram‐scale synthesis of enantioenriched cyclic 1,4‐diketones, and stereoselective transformations of the products by hydrogenation, allylation, and isomerization.
