Experiments on the Interaction of a Modulated Electron Beam with a Plasma
Creators: name: Boyd, Gary D.
Publisher: name: California Institute of Technology
Year: 1959

description: New experiments are performed concerning the high frequency interactions of electron beams and plasmas. A modulated (500 Mc and 3000 Mc) electron beam is passed through a uniform plasma region of a mercury arc discharge, after which it is demodulated. Exponentially growing wave amplification along the electron beam is observed for the first time at a modulation frequency equal to the plasma frequency. No constant magnetic fields are used in these experiments. Calculations based on the one dimensional analysis of Bohm and Gross of an electron beam passing through a plasma are made to predict the effects of the random energy of the plasma electrons and collisions. By studying the interaction of a finite diameter beam and a plasma with no thermals or collisions, it is shown that the effect of the finite geometry is to reduce the growth constant.

Recent work by Trivelpiece and Gould has pointed out that a plasma column in free space may propagate forward and backward waves at a velocity small compared to the velocity of light. The experimental techniques of passing a modulated electron beam through the plasma, as described above, are applied to observe traveling wave type of interaction with the slow wave mode of propagation in the absence of any magnetic fields. Theory predicting experimental rates of growth is presented. Experimental results in good agreement with theory are presented.

In the course of verifying plasma density measurements, the excitation of the dipole resonance of a plasma column is considered. Multiple resonances are observed and discussed.
description: I sincerely wish to extend my appreciation to Professor Roy W. Gould and Professor Lester M. Field for their continued interest and participation in this research. Their contributions have been most valuable.

A great deal of credit for the success of these experiments is attributable to Mr. A. F. Carpenter whose skill and patience in the fabrication of the glass tubes is gratefully acknowledged. Thanks are also extended to Mr. Eric Gelin and Mr. Bob Stratton who constructed the experimental equipment. Mrs. Ruth Stratton is thanked for her patience in the preparation of the manuscript.

Many fruitful discussions were enjoyed with Dr. A. W. Trivelpiece and Professor D. G. Dow with regard to both experiment and theory. Mr. John F. Asmus is thanked for his assistance with experiments and computations.

The contributions of other members of the California Institute of Technology in the education of the author over the past years are too numerous to mention, but are sincerely appreciated.

The author was privileged and fortunate to enjoy fellowships from the Francis Cole, General Electric, Schlumberger and Westinghouse Foundations. Their financial assistance is most appreciated.

Power Flow and Gap Coupling to Slow Wave Plasma Modes
Creators: name: Boyd, Gary D.
Publisher: name: California Institute of Technology
Year: 1959

description: The interaction impedance for the slow wave plasma modes of Trivelpiece and Gould is obtained for a coaxial system of plasma column, surrounding dielectric and conducting surface. The theory presented includes a finite axial magnetic field. Calculations are presented for the special case of no static magnetic field for the so-called surface wave interaction impedance versus βa.

Coupling to the slow wave plasma modes by a known electric field across a gap in the conducting surface at the dielectric surface is analyzed for the coaxial plasma system including a static axial magnetic field. Such an analysis follows that of Sensiper. This results in an impedance as seen by the cavity gap. Calculations are presented for the special case of no static magnetic field.
description: The author wishes to express his sincere appreciation to Professors Roy W. Gould and Daniel G. Dow for several illuminating discussions of the theory presented.

description: Jose Panganiban is a coastal municipality in the province of Camarines Norte. The Municipality was formerly named Mambulao taken from the word “Mambulawan” meaning abundant of gold, The Municipality of Jose Panganiban is a 2nd class municipality of Camarines Norte, Philippines. The route from Jose Panganiban to Daet faces significant challenges due to a disorganized scheduling system for public utility vehicles (PUVs), particularly vans. This research aims to develop a strategic, simulation-based solution to optimize the scheduling of PUVs on this route. By modeling various van departure schedules and frequencies, the study will explore how scheduling adjustments can alleviate overcrowding, reduce waiting times, and improve overall travel efficiency, particularly during peak hours. Stress, anxiety, and frustration experienced by people during their commute can decrease their productivity at work, increase levels of counterproductive work behavior, and lower their engagement with organizational citizenship behavior. The researchers found out through using Discrete Event Simulation Algorithm that departure time of vans are greatly affected by factors such as arrival time, waiting/loading time, peak/non-peak hours rate. The findings of this study lowered the current waiting time of 25 minutes down to 21.60 minutes.

Description and discussion
Specimens are about 1 mm long (Fig. 10E) and can be placed within ‘Protoplanellinae’ due to the ventral position of the testes relative to the vitellaria and the separate protonephridiopores (see Reisinger 1924). Additionally, sectioned specimens clearly show ciliated pits (Fig. 10B: cp) at the anterior body end. Within ʻProtoplanellinae’, the only genus containing species with such pits is Prorhynchella (Van Steenkiste et al. 2010). Moreover, the studied specimens also possess the typical proboscis-like organ (Fig. 10B: plo) associated with a glandular complex (Fig. 10B: gl) that is unique for this monospecific genus (described as ‘rüssel-like organ’ by Ruebush 1939).
The only difference between our specimens and the original description of P. minuta is the position of the protonephridiopores (Fig. 10A: pp), which are situated somewhat more posteriorly compared to the original description (Ruebush 1939).
The studied specimens show some intraspecific variation in the structure of the bursa (Fig. 10A, C–F: bu). In one specimen, this is merely an evagination of the genital atrium while in another it is an oval, thin-walled structure, filled with sperm (compare Fig. 10C–D, F). It is connected to the genital atrium (Fig. 10A, D: ga) by a long bursal stalk (Fig. 10C, F: bs), which is surrounded by very strong sphincters (Fig. 10C, F: sph). Only two sphincters were visible on live specimens (Fig. 10F), but at least six were counted in one sectioned specimen (Fig. 10C). In the original description of P. minuta, Ruebush (1939) describes a bursa with a stalk, similar to the situation in most of our specimens (Fig. 10C, F). Whether or not the specimen drawn in Fig. 10D is an aberration is not clear: The specimen appears fully adult, hence the poorly developed bursal structure is unlikely a result of a different degree of development. With the data available to us, it is difficult to speculate on the biological significance of this reduced organ and we hence refrain from drawing conclusions on the matter.

French: Mélanomys a longue queue / German: Harris-Reiswasserratte / Spanish: Rata de agua de Harris
Other common names: Long-tailed Montane Rat, Long-tailed Sigmodontomys
Taxonomy. Oryzomys aphrastus Harris, 1932, San Joaquin de Dota, 1219 m, San José Province, Costa Rica.
Tanyuromys aphrastus is the type species of the genus. Monotypic.
Distribution. SE Costa Rica, W Panama, W Ecuador; and probably Colombia.
Descriptive notes. Head-body 116-152 mm, tail 176-235 mm, ear 17 mm, hindfoot 35-40 mm; weight 63 g. Harris’s Rice Water Rat is a medium-sized, very long-tailed oryzomyine, with long and robust hindfeet. Pelage is long and soft, upperparts are grizzled dark brown with orange highlights, and underparts are paler gray, with pronounced ocherous highlight. Dorso-ventral countershading is subtle. Ears are small and sparsely to moderately covered with blackish, dark brown, or reddish brown hair. Mystacial and superciliary vibrissae are very long. Manus and pes have sparse to moderate cover of pale brown to dark brown hairs dorsally. Hindfeet lack well-developed natatory fringes and interdigital webs and have sparse ungual tufts covering tips of claws. Tail is unicolored brown and sparsely haired, terminating in short tuft. Four pairs of mammae are present.
Habitat. Mature primary or secondary forests at elevations of 1200-2500 m. Habitat of Harris’s Rice Water Rat is characterized by lush evergreen forests where canopy height and continuity decrease with elevation and epiphyte and moss cover increase with elevation. Where an adult was caught in Monteverde Cloud Forest Reserve, Costa Rica, forest had a tall, somewhat broken canopy (15-30 m), with heavy epiphyte and moss growth and multilayered understory of ferns, shrubs, herbs, young trees, and monocots.
Food and Feeding. Molars of Harris’s Rice Water Rat have unique occlusal pattern, with tendency to lophodonty and probably associated with some degree of herbivory.
Breeding. No information.
Activity patterns. Harris’s Rice Water Rat is terrestrial; all collected specimens were trapped on ground.

Theory of Parametrically-Pumped Longitudinal-Field Electron Beams
Creators: name: Forster, Donald C.
Publisher: name: California Institute of Technology
Year: 1960

description: The general equations describing electron beams which have been excited by both a moderately strong pump source (or local oscillator) and a weak signal source are formulated in terms of coupled modes, including coupling to slow-wave circuits, and solved numerically for four problems of interest:

a) space-charge pumped longitudinal parametric amplifiers

b) circuit-pumped longitudinal parametric amplifiers

c) parametric cooling of slow space-charge waves, and

d) traveling-wave tubes with pump space-charge waves excited on the electron stream.

Emphasis is placed on the parametric amplifier solutions, and realization of noise temperatures as low as 55°K are indicated.  A discussion of the form of the general equations leads to new concepts about the coupling of positive and negative energy carriers through the action of parametric pumping.

Experimental results are presented which tend to verify qualitatively some of the theoretical predictions for the behavior of the parametric amplifiers.

Myrmeleon wangi

description: Myrmeleon wangi group
Diagnosis
The M. wangi group can be characterized by the hindwing shorter than the forewing; hindwing RP at origin runs closer to MA; male genitalia with gonarcus arched, membrane with short black setae, mediuncus well sclerotized, inverted V-shaped in caudal view, parameres well sclerotized, triangular in caudal view, the larvae with brown markings on coxae.
Included species
Myrmeleon wangi Miller & Stange, 1999 stat. rev.
Possible candidates: Myrmeleon formicarius Linnaeus, 1767, M. punicanus Pantaleoni & Badano, 2012, M. trivialis Gerstaecker, 1885
Remarks
Several other Old World species have a similar structure in the male genitalia comparing with M. wangi, including M. formicarius, M. punicanus and M. trivialis. The male genitalia of these species are similar to those of M. wangi in the overall shape of the gonarcus and with short, black setae on the membrane. However, the mediuncus of M. wangi is an inverted V-shape in caudal view (Fig. 16C), as the mediuncus of the other three species appears to be three-pronged. The male genitalia of these species can be distinguished from those of Baliga by the presence of short, black setae on the membrane, as well as the lack of an additional dorsal process on the mediuncus, which is present in species of Baliga in lateral view (Figs 4A, 7A) (Pantaleoni & Badano 2012; Sekimoto 2014; Hassan et al. 2022). The above-mentioned species likely belong to a closely related or the same species group as M. wangi, but additional research is required. If these species are proven to be in the same species group, this group should be redesignated as Myrmeleon formicarius group.

Black-and-Yellow Rice Rat
Melanomys chrysomelas
French: Mélanomys noir et jaune / German: Schwarzgelbe Dunkelreisratte / Spanish: Rata arrocera negra y dorada
Taxonomy. Oryzomys chrysomelas J. A. Allen, 1897, Suerre, Limon, Costa Rica.
M. chrysomelas is traditionally subsumed under M. caliginosus; here it is resurrected following molecular results of|. D. Hanson and R. D. Bradley in 2008. A complete revision of the genus is pending. Monotypic.
Distribution. SW Honduras, Nicaragua, and Costa Rica; occurrence in Panama uncertain.
Descriptive notes. Head-body 110-130 mm, tail 80-100 mm, hindfoot 24— 28 mm. No specific data are available for body weight. Melanomys includes mediumsized vole-like oryzomyines, with tails shorter than head-body length. Dorsum is dark brown; venteris grayish or yellowish brown. Ears are small and slightly hairy. Mystacial vibrissae are short and sparse. Manus and pes are covered dorsally with short and dark hair, and manual claws are long and keeled. Tail is unicolored and dark, sparsely haired, without apical tuft. There are four pairs of mammae. Upperparts of the Black-and-Yellow Rice Rat are very dark brown; hairs are conspicuously tipped with yellowish rufous; sides are brighter and more rufous than back; underparts have yellowish brown tips on long hairs, concealing plumbeous basal part of pelage; ears are black; feet and tail are dark brownish black, and tail is not appreciably lighter below. Chromosomal complement is 2n = 56, FN = 58.
Habitat. Evergreen humid forests from near sea level to elevations of ¢.1000 m (more commonly below 500 m). The Black-and-Yellow Rice Rat also occurs in abandoned plantations, and individuals have been trapped around leaves and other debris associated with logs and buttress of large trees.
Food and Feeding. Stomach contents of Black-and-Yellow Rice Rats contained plant material; captive individuals preyed on insects.
Breeding. Pregnant or lactating Black-and-Yellow Rice Rats were recorded in February—March and August; eleven pregnant females has an average of 3-5 embryos (range 1-6); and one female had postpartum estrus.
Activity patterns. The Black-and-Yellow Rice Rat is terrestrial and apparently nocturnal and diurnal.
Movements, Home range and Social organization. No information.
Status and Conservation. Not assessed on The IUCN Red List as a separate species from the Dusky Rice Rat (M. caliginosus), which is classified as Least Concern.

description: Akute myeloische Leukämie (AML) ist eine maligne Neoplasie des blutbildenden Systems und stellt sich als eine höchst heterogene Krankheit dar und, mit besonderem Augenmerk auf die molekularen Eigenschaften und einer breiten Vielfalt an Oberflächenmarkern. Experimente im Mausmodell zeigen eine hierarchische Organisation von AML, wobei die Fähigkeit, Leukämie zu initiieren, aufrecht zu erhalten und Rückfälle zu provozieren einer seltenen Subgruppe vorbehalten ist, den sogenannten Leukämie-initiierenden Zellen (LICs) oder auch Leukämische Stammzellen (LSCs). In unserer Analyse nutzten wir patient-derived xenotransplantation (PDX) in immunosupprimierten NSG Modellen, um eine tiefergreifende Charakterisierung primärer humaner AML-Zellen zu erreichen. Dadurch wollen wir ein besseres Verständnis der Krankheit und der molekularen Risikogruppen etablieren. Zusätzlich analysierten wir eine Kohorte an Primärproben von AML Patienten um den Phänotyp in Patientenzellen mit dem nach Propagierung dieser Zellen in den NSG Mäusen zu vergleichen. Wir beobachteten, dass die höchste Anzahl an leukämischen Stammzellen (LSCs), welche entweder durch CD34 Positivität oder die Abwesenheit von NKG2D Liganden (es wurde gezeigt, dass sie die Immunevasion von LSCs identifizieren können) definiert wurden, in der “ungünstigen” molekularen Risikogruppe aufzufinden war und dass LSC-Marker wie CD117, CLL-1 niedrig, CD200 und GPR56 die phänotypischen Merkmale von LSCs teilen, wohingegen Immun Checkpoint-Marker wie CD80, CD86 und CD276 mit einem Nicht-LSC Phänotyp assoziiert sind. Die Adhäsions-Marker sind überraschenderweise ebenfalls auf Nicht-LSC erhöht. Interessanterweise wurden diese phänotypischen Merkmale über den Transplantationsprozess zumeist konserviert, sodass kaum phänotypische Unterschiede resultierten. Zusammenfassend zeigt unsere Studie, dass das NSG-abgeleitete PDX Modell ein verlässliches Instrument ist. Die Expansion der AML-Zellen im Mausmodell erlaubt es uns, ihren Phänotyp über einen weiterreichenden Zeitraum zu erforschen und machte es darüber hinaus möglich, ein tieferes Verständnis der zugrundeliegenden Mechanismen zu erlangen.

Small robust leafhoppers. Macropterous. Head and thorax with granulate surface. Head slightly wider than pronotum, hind margin sinuately curved behind eyes; crown of head not much shortened medially. Face including eyes wider than long. Ocelli closer to each other than to adjacent eyes. Transclypeal suture absent, lateral margins of gena slightly concave beneath eyes. Pronotum with hind margin almost straight, anterior margin convex. Scutellum distinctly shorter than median length of pronotum. Forewings with inner and median subapical cells subdivided with cross veins. Fore femur with intercalary row of setae as thick as anteromedian row and arranged in arcuate row; anteroventral row of setae with AV1 located ventrad of intercalary row (Fig. 20 E). Hind femoral macrosetae 2+1. Hind tibial spinulation PD 5, AD 6, AV 5; metabasitarsomere with one platella and three setae on apical transverse row.
Male genitalia. Pygofer lobe constricted in posterior 0.33 and narrowed. Subgenital plates elongate oval with hair-like marginal setae. Styles with anterior lobe much shorter than posterior, inner fork about as longer as outer fork. Connective broader than long, anterior margin roundly produced, posterior margin medially concavely excavated. Aedeagus with long preatrium and pair of ventral processes sparsely covered with minute setae; shaft cylindrical, devoid of processes, strongly hooked with apical gonopore. Anal collar without process.
Female. Unknown.
Distribution. China (Yunnan).
Etymology. The generic name is derived from combination of two words Purvi + agallia, the prefix is a Sanskrit word meaning early. The gender of the genus is feminine.
Remarks. Purvigallia belongs to the group of genera with the hind margin of the head sinuate. It closely resembles Japanagallia in having a cross vein between the claval veins but is more robust and the ocelli are closer to each other than to adjacent eyes. It also resembles Igerna and Ianagallia in external appearance but differs from Igerna in having a pair of ventral processes on the aedeagus and from Ianagallia in lacking a stout dorsal apodeme and having the aedeagal shaft stouter.

Bandwidth Limitations and Synthesis Procedures for Negative Resistance and Variable Reactance Amplifiers
Creators: name: Aron, Richard M.
Publisher: name: California Institute of Technology
Year: 1960

description: The bandwidth limitation on the reflection coefficient of circuits containing a reactance limited negative conductance such as a tunnel diode is derived, and the insertion loss method of modern network theory is adapted to the synthesis of low pass ladder equivalents of amplifiers containing these elements. Amplifiers which have a considerable bandwidth advantage over simple single tuned circuits, and which approach the ultimate bandwidth limit as rapidly as possible as the number of passive components is increased, are demonstrated.

Fundamental bandwidth limitations of three-frequency nonlinear reactance amplifiers, parametric amplifiers, and non-inverting upconverters are also found. A low pass ladder equivalent circuit and the insertion loss method are shown to be useful tools for synthesis of these amplifiers. Considerable bandwidth advantage over single-tuned circuits is again demonstrated. Syntheses which yield the ultimate bandwidth as the number of circuit elements is increased are found.

These synthesis methods and the reverse predistortion technique are used to synthesize stable amplifiers whose bandwidth capability increases almost linearly with the number of active elements employed.

Relationships between physically achievable amplifier circuits and the low pass equivalents are shown, and the general compatibility of presently available active elements with these circuits is considered.

Theory of the Valence Band Energy Level Structures of Germanium and Silicon in an External Magnetic Field
Creators: name: Evtuhov, Viktor
Publisher: name: California Institute of Technology
Year: 1960

description: The problem of the valence band structure of Ge and Si in the presence of an external magnetic field is considered from a quantum mechanical point of view. The analysis is carried out using first and second order perturbation theory. The approach is, in principle, similar to that of W. Shockley and E. O. Kane, but is modified in some important essentials to include the effects of the magnetic field. The analytical results obtained are somewhat more general than those of J. M. Luttinger but reduce to the latter if certain approximations are introduced. Numerical calculations of the Landau energy levels are carried out for certain special cases, of which the most important are the following:

1. Magnetic field ϰ in the [001] direction, k_H = 0; nonspherical symmetry character of energy bands and the coupling of V_1 and V_2 bands to the V_3 band included.

2. Magnetic field ϰ in the [001] direction, k_H ≠ 0; nonspherical symmetry character of energy bands included, decoupling of V_1 and V_2 bands from the V_3 band assumed.

In addition, a set of algebraic equations is derived whose solution should yield the valence band Landau levels for the cases of the magnetic field in the [101] and the [111] directions. However, no numerical calculations are performed for these cases.

The results of the calculations indicate the presence of some interesting transitions between the Landau levels of Ge and Si, as well as the possible presence of other interesting effects which may be observable. Certain of these seem to offer potential millimeter-wave applications possibilities, some of which are discussed.
